The appropriate management of atypical chest pain requires an integration of medical and behavioural treatments. Unnecessary medicalization can increase morbidity. A sensitivity to the behavioural factors contributing to symptoms and disability may reduce both. The purpose of this paper is to provide physicians with a cognitive-behavioural perspective of the nature of morbidity and disability associated with chronic chest discomfort; some strategies for detecting heretofore unsuspected disability associated with chronic chest pain and related discomfort in patients with organic findings (both cardiac and non-cardiac), as well those with no identifiable disease process or organic cause; and some simple behavioural and cognitive-behavioural therapeutic techniques for treating and preventing such problems.

Patients with non-cardiac chest pain (NCCP) suffer from recurrent chest pain and make substantial use of healthcare resources. To explore the prevalence of depressive symptoms, cardiac anxiety, and fear of body sensations in patients discharged with a NCCP diagnosis; and to describe how depressive symptoms, cardiac anxiety, and fear of body sensations are related to each other and to healthcare-seeking behavior. Cross-sectional design. Data were collected between late October 2013 and early January 2014 in 552 patients with NCCP from four hospitals in southeast Sweden, using the Patient Health Questionnaire-9, Cardiac Anxiety Questionnaire, and Body Sensations Questionnaire. About 26 % (n = 141) of the study participants reported at least moderate depressive symptoms, 42 % (n = 229) reported at least moderate cardiac anxiety, and 62 % (n = 337) reported some degree of fear of body sensations. We found strong positive relationships between depressive symptoms and cardiac anxiety (r s = 0.49; P < 0.01), depressive symptoms and fear of body sensations (r s = 0.50; P < 0.01), and cardiac anxiety and fear of body sensations (r s = 0.56; P < 0.01). About 60 % of the participants sought care because of chest pain once, 26 % two or three times, and the rest more than three times. In a multivariable regression analysis, and after adjustment for multimorbidity, cardiac anxiety was the only variable independently associated with healthcare-seeking behavior. Patients with NCCP and many healthcare consultations had high levels of depressive symptoms and cardiac anxiety, and moderate levels of fear of body sensations. Cardiac anxiety had the strongest relationship with healthcare-seeking behavior and may therefore be an important target for intervention to alleviate suffering and to reduce healthcare use and costs.

The rapid exclusion of acute myocardial infarction in patients with chest pain can reduce the length of hospital admission, prevent unnecessary diagnostic work-up and reduce the burden on our health-care systems. The combined use of biomarkers that are associated with different pathophysiological aspects of acute myocardial infarction could improve the early diagnostic assessment of patients presenting with chest pain. We measured cardiac troponin I, copeptin and heart-type fatty acid-binding protein concentrations in 584 patients who presented to the emergency department with acute chest pain. The diagnostic performances for the diagnosis of acute myocardial infarction and NSTEMI were calculated for the individual markers and their combinations. Separate calculations were made for patients presenting to the emergency department <3 h, 3-6 h and 6-12 h after chest pain onset. For ruling out acute myocardial infarction, the net predictive values (95% CI) of cardiac troponin I, copeptin and heart-type fatty acid-binding protein were 90.4% (87.3-92.9), 84% (79.8-87.6) and 87% (83.5-90), respectively. Combining the three biomarkers resulted in a net predictive value of 95.8% (92.8-97.8). The improvement was most pronounced in the early presenters (<3 h) where the combined net predictive value was 92.9% (87.3-96.5) compared to 84.6% (79.4-88.9) for cardiac troponin I alone. The area under the receiver operating characteristic for the triple biomarker combination increased significantly (P < 0.05) compared to that of cardiac troponin I alone (0.880 [0.833-0.928] vs. 0.840 [0.781-0.898], respectively). Combining copeptin, heart-type fatty acid-binding protein and cardiac troponin I measurements improves the diagnostic performance in patients presenting with chest pain. Importantly, in patients who present early (<3 h) after chest pain onset, the combination improves the diagnostic performance compared to the standard cardiac troponin I measurement alone. © The Author(s) 2015.

Because the frequency of cardiac event rates is low among chest pain patients following either performance of coronary CT angiography (CCTA) or stress testing, there is a need to better assess how these tests influence the central management decisions that follow from cardiac testing. The present study was performed to assess the relative impact of CCTA vs stress testing on medical therapies and downstream resource utilization among patients admitted for the work-up of chest pain. The admitted patients were randomized in a 1:1 ratio to either cardiac imaging stress test or CCTA. Primary outcomes were time to discharge, change in medication usage, and frequency of downstream testing, cardiac interventions, and cardiovascular re-hospitalizations. We randomized 411 patients, 205 to stress testing, and 206 to CCTA. There were no differences in time to discharge or initiation of new cardiac medications at discharge. At 1 year follow-up, there was no difference in the number of patients who underwent cardiovascular downstream tests in the CCTA vs stress test patients (21% vs 15%, P = .1) or cardiovascular hospitalizations (14% vs 16%, P = .5). However, there was a higher frequency of invasive angiography in the CCTA group (11% vs 2%, P = .001) and percutaneous coronary interventions (6% vs 0%, P < .001). Randomization of hospitalized patients admitted for chest pain work-up to either CCTA or to stress testing resulted in similar discharge times, change in medical therapies at discharge, frequency of downstream noninvasive testing, and repeat hospitalizations. However, a higher frequency of invasive coronary angiography and revascularization procedures were performed in the CCTA arm. (ClinicalTrials.gov number, NCT01604655.).

Non-Acute Coronary Syndrome Anginal Chest Pain

2010-01-01

Anginal chest pain is one of the most common complaints in the outpatient setting. While much of the focus has been on identifying obstructive atherosclerotic coronary artery disease (CAD) as the cause of anginal chest pain, it is clear that microvascular coronary dysfunction (MCD) can also cause anginal chest pain as a manifestation of ischemic heart disease (IHD), and carries an increased cardiovascular risk. Epicardial coronary vasospasm, aortic stenosis, left ventricular hypertrophy, congenital coronary anomalies, mitral valve prolapse and abnormal cardiac nociception can also present as angina of cardiac origin. For non-acute coronary syndrome (ACS) stable chest pain, exercise treadmill testing (ETT) remains the primary tool for diagnosis of ischemia and cardiac risk stratification; however, in certain subsets of patients, such as women, ETT has a lower sensitivity and specificity for identifying obstructive CAD. When combined with an imaging modality, such as nuclear perfusion or echocardiography testing, the sensitivity and specificity of stress testing for detection of obstructive CAD improves significantly. Advancements in stress cardiac magnetic resonance imaging (MRI) enables detection of perfusion abnormalities in a specific coronary artery territory, as well as subendocardial ischemia associated with MCD. Coronary computed tomography angiography (CCTA) enables visual assessment of obstructive CAD, albeit with a higher radiation dose. Invasive coronary angiography (CA) remains the gold standard for diagnosis and treatment of obstructive lesions that cause medically refractory stable angina. Furthermore, in patients with normal coronary angiograms, the addition of coronary reactivity testing (CRT) can help diagnose endothelial dependent and independent microvascular dysfunction. Life-style modification and pharmacologic intervention remains the cornerstone of therapy to reduce morbidity and mortality in patients with stable angina. This review focuses on the pathophysiology, diagnosis, and treatment of stable, non-ACS anginal chest pain. PMID:20380951

Atypical clinical presentation in acute myocardial infarction (AMI) patients is not uncommon; most studies suggest that it is associated with unfavorable prognosis. Long-term clinical impact differs according to predominant symptom presentation (typical chest pain, atypical chest pain, syncope, cardiac arrest, or dyspnea) in AMI patients. FAST-MI 2010, a nationwide French registry, included 4169 patients with AMI in 213 centers at the end of 2010 (76% of active centers). Demographics, medical history, hospital management, and outcomes were compared according to predominant symptom presentation. Typical chest pain with no other symptom was reported in 3020 patients (68% in STEMI patients, 76% in NSTEMI patients). Atypical chest pain, dyspnea, syncope, and cardiac arrest were reported in 11%, 11%, 5%, and 1%, respectively. Patients with atypical clinical presentation had a higher cardiovascular risk profile and received fewer medications and a less invasive strategy. Using Cox multivariate analysis, atypical chest pain was not associated with higher death rate at 3 years (HR: 0.96, 95% CI: 0.69-1.33, P = 0.78), whereas cardiac arrest (HR: 2.44, 95% CI: 1.00-5.97, P = 0.05), syncope (HR: 1.70, 95% CI: 1.18-2.46, P = 0.005), and dyspnea (HR: 1.66, 95% CI: 1.31-2.10, P < 0.001) were associated with higher long-term mortality compared with patients with typical isolated chest pain. Similar trends were observed in STEMI and NSTEMI populations. Atypical clinical presentation is observed in about 20% of AMI patients. Cardiac arrest, dyspnea, and syncope represent independent predictors of long-term mortality in STEMI and NSTEMI populations. © 2017 Wiley Periodicals, Inc.

We assessed the occurrence and aetiology of chest pain in primary care practice. These features differ between primary and emergency care settings, where most previous studies have been performed. 59 GPs in western Switzerland recorded all consecutive cases presenting with chest pain. Clinical characteristics, laboratory tests and other investigations as well as the diagnoses remaining after 12 months of follow-up were systematically registered. Among 24,620 patients examined during a total duration of 300 weeks of observation, 672 (2.7%) presented with chest pain (52% female, mean age 55 +/- 19(SD)). Most cases, 442 (1.8%), presented new symptoms and in 356 (1.4%) it was the reason for consulting. Over 40 ailments were diagnosed: musculoskeletal chest pain (including chest wall syndrome) (49%), cardiovascular (16%), psychogenic (11%), respiratory (10%), digestive (8%), miscellaneous (2%) and without diagnosis (3%). The three most prevalent diseases were: chest wall syndrome (43%), coronary artery disease (12%) and anxiety (7%). Unstable angina (6), myocardial infarction (4) and pulmonary embolism (2) were uncommon (1.8%). Potentially serious conditions including cardiac, respiratory and neoplasic diseases accounted for 20% of cases. A large number of laboratory tests (42%), referral to a specialist (16%) or hospitalisation (5%) were performed. Twentyfive patients died during follow-up, of which twelve were for a reason directly associated with thoracic pain [cancer (7) and cardiac causes (5)]. Thoracic pain was present in 2.7% of primary care consultations. Chest wall syndrome pain was the main aetiology. Cardio - vascular emergencies were uncommon. However chest pain deserves full consideration because of the occurrence of potentially serious conditions.

This article is a clinically relevant review of the existing medical literature relating to the assessment and diagnostic evaluation for athletes complaining of nontraumatic chest pain. The literature was searched using the following databases for the years 1975 forward: Cochrane Database of Systematic Reviews; CINAHL; PubMed (MEDLINE); and SportDiscus. The general search used the keywords chest pain and athletes. The search was revised to include subject headings and subheadings, including chest pain and prevalence and athletes. Cross-referencing published articles from the databases searched discovered additional articles. No dissertations, theses, or meeting proceedings were reviewed. The authors discuss the scope of this complex problem and the diagnostic dilemma chest pain in athletes can provide. Next, the authors delve into the vast differential and attempt to simplify this process for the sports medicine physician by dividing potential etiologies into cardiac and noncardiac conditions. Life-threatening causes of chest pain in athletes may be cardiac or noncardiac in origin, which highlights the need for the sports medicine physician to consider pathology in multiple organ systems simultaneously. This article emphasizes the importance of ruling out immediately life threatening diagnoses, while acknowledging the most common causes of noncardiac chest pain in young athletes are benign. The authors propose a practical algorithm the sports medicine physician can use as a guide for the assessment and diagnostic work-up of the athlete with chest pain designed to help the physician arrive at the correct diagnosis in a clinically efficient and cost-effective manner.

Spinal cord processing of cardiac nociception: are there sex differences between male and proestrous female rats?

Sex differences in the characteristics of cardiac pain have been reported from clinical studies. For example, women experience chest pain less frequently than men. Women describe their chest pain as sharp and stabbing, while men have chest pain that is felt as a pressure or heaviness. Pain is also referred to the back more often in women than men. The mechanisms underlying sex differences in cardiac pain are unknown. One possible mechanism for the observed differences could be related to plasma estradiol. This study investigated the actions of estradiol on the activity of T(3) spinal neurons that process cardiosomatic information in male and female rats. Extracellular potentials of T(3) spinal neurons were recorded in response to mechanical somatic stimulation and noxious chemical cardiac stimulation in pentobarbital-anesthetized male and proestrous female rats. Fifty one percent and fifty percent of neurons responded to intrapericardial algogenic chemicals (0.2 ml) in male and female rats, respectively. Somatic fields were located by applying brush, pressure, and pinch to the upper body. Of those neurons receiving cardiac input, 54% in female and 55% in male rats also received somatic input. In both male and female rats, 81% of neurons responding to somatic stimuli had somatic fields located on the side of the upper body, while 19% of neurons had somatic fields located on the chest. These results indicate there are no significant differences in the responses of T(3) spinal neurons to cardiosomatic stimulation between male and proestrous female rats, despite differences in estradiol levels.

Myocardial perfusion imaging (MPI) with technetium-99m sestamibi (Tc-99m MIBI) is considered a diagnostic technique that is widely used for the investigation of suspected coronary artery disease. Incidental inspection of an extracardiac activity is indirect, but important marker, which can identify a potentially treatable non-coronary cause for chest pain that may mimic cardiac symptoms. Here, we present an illustrative case in which significant enterogastroesophageal reflux of Tc-99m MIBI occurred during the cardiac imaging following prompt hepatobiliary clearance. Because, there was normal myocardial perfusion on MPI, presence of gastroesophageal reflux (GER) on GER scintigraphy and detection of mild inflammation with pathologically confirmed hyperplastic polyp by endoscopy, in view of the above findings we concluded that the probable cause of chest pain was reflux.

Ischemia-modified albumin (IMA) has been suggested as a marker of cardiac ischemia. Little, however, is known about its capacity to predict short-term serious cardiac outcomes (death, myocardial infarction, congestive heart failure, serious arrhythmia, or refractory ischemic cardiac pain) in patients arriving at the emergency department with symptoms that may indicate cardiac ischemia. We screened 546 patients over a 4-week period, of whom 189 fulfilled our entry criteria by presenting to an emergency department with potential cardiac-ischemia symptoms within 6 hours after chest pain, seeing an emergency physician who chose to order a troponin I test, and having no serious cardiac outcome before the troponin result became available. We followed the study patients for 72 hours to determine if any experienced a serious cardiac outcome. We calculated the likelihood ratios (LRs) of IMA findings predicting serious cardiac outcomes that could not be diagnosed at presentation with current techniques. Of the 189 patients, 24 had a serious cardiac outcome within 72 hours after their arrival at the emergency department. The likelihood ratios for IMA measurement within 6 hours after chest pain predicting a serious cardiac outcome within the next 72 hours were 1.35 (95% confidence interval [CI] 0.315-5.79) for IMA < or = 80 U/mL and 0.98 (95% CI 0.86- 1.11) for IMA > 80 U/mL. These data suggest that in patients presenting with chest pain who have not yet experienced a serious cardiac event, IMA is a poor predictor of serious cardiac outcomes in the short term.

Chest tube removal is an extremely painful procedure and patients may not respond well to palliative therapies. This study aimed to examine the effect of cold and music therapy individually, as well as a combination of these interventions on reducing pain following chest tube removal. A factorial randomized-controlled clinical trial was performed on 180 patients who underwent cardiac surgery. Patients were randomized into four groups of 45. Group A used ice packs for 20 minutes prior to chest tube removal. Group B was assigned to listen to music for a total length of 30 minutes which started 15 minutes prior to chest tube removal. Group C received a combination of both interventions; and Group D received no interventions. Pain intensity was measured in each group every 15 minutes for a total of 3 readings. Analysis of variance, Tukey and Bonferroni post hoc tests, as well as repeated measures ANOVA were employed for data analysis. Cold therapy and combined method intervention effectively reduced the pain caused by chest tube removal (P < 0.001). Additionally, there were no statistically significant difference in pain intensity scores between groups at 15 minutes following chest tube removal (P = 0.07). Cold and music therapy can be used by nursing staff in clinical practice as a combined approach to provide effective pain control following chest tube removal. Copyright © 2018 Elsevier Ltd.

Patients with potentially ischemic chest pain are commonly admitted to the hospital or observed after a negative evaluation in the emergency department (ED) owing to concern about adverse events. Previous studies have looked at 30-day mortality, but no current large studies have examined the most important information regarding ED disposition: the short-term risk for a clinically relevant adverse cardiac event (including inpatient ST-segment elevation myocardial infarction, life-threatening arrhythmia, cardiac or respiratory arrest, or death). To determine the incidence of clinically relevant adverse cardiac events in patients hospitalized for chest pain with 2 troponin-negative findings, nonconcerning initial ED vital signs, and nonischemic, interpretable electrocardiographic findings. We conducted a blinded data review of 45,416 encounters obtained from a prospectively collected database enrolling adult patients admitted or observed with the following inclusion criteria: (1) primary presenting symptom of chest pain, chest tightness, chest burning, or chest pressure and (2) negative findings for serial biomarkers. Data were collected and analyzed from July 1, 2008, through June 30, 2013, from the EDs of 3 community teaching institutions with an aggregate census of more than 1 million visits. We analyzed data extracted by hypothesis-blinded abstractors. The primary outcome was a composite of life-threatening arrhythmia, inpatient ST-segment elevation myocardial infarction, cardiac or respiratory arrest, or death during hospitalization. Of the 45,416 encounters, 11,230 met criteria for inclusion. Mean patient age was 58.0 years. Of the 11 230 encounters, 44.83% of patients arrived by ambulance and 55.00% of patients were women. Relevant history included hypertension in 46.00%, diabetes mellitus in 19.72%, and myocardial infarction in 13.16%. The primary end point occurred in 20 of the 11 230 patients (0.18% [95% CI, 0.11%-0.27%]). After excluding patients with abnormal vital signs, electrocardiographic ischemia, left bundle branch block, or a pacemaker rhythm, we identified a primary end point event in 4 of 7266 patients (0.06% [95% CI, 0.02%-0.14%]). Of these events, 2 were noncardiac and 2 were possibly iatrogenic. In adult patients with chest pain admitted with 2 negative findings for serial biomarkers, nonconcerning vital signs, and nonischemic electrocardiographic findings, short-term clinically relevant adverse cardiac events were rare and commonly iatrogenic, suggesting that routine inpatient admission may not be a beneficial strategy for this group.

Chest pain: coronary CT in the ER

Maffei, Erica; Seitun, Sara; Guaricci, Andrea I

Cardiac CT has developed into a robust clinical tool during the past 15 years. Of the fields in which the potential of cardiac CT has raised more interest is chest pain in acute settings. In fact, the possibility to exclude with high reliability obstructive coronary artery disease (CAD) in patients at low-to-intermediate risk is of great interest both from the clinical standpoint and from the management standpoint. Several other modalities, with or without imaging, have been used during the past decades in the settings of new onset chest pain or in acute chest pain for both diagnostic and prognostic assessment of CAD. Each one has advantages and disadvantages. Most imaging modalities also focus on inducible ischaemia to guide referral to invasive coronary angiography. The advent of cardiac CT has introduced a new practice diagnostic paradigm, being the most accurate non-invasive method for identification and exclusion of CAD. Furthermore, the detection of subclinical CAD and plaque imaging offer the opportunity to improve risk stratification. Moreover, recent advances of the latest generation CT scanners allow combining both anatomical and functional imaging by stress myocardial perfusion. The role of cardiac CT in acute settings is already important and will become progressively more important in the coming years. PMID:26866681

Chest pain in children and adolescents is rarely associated with cardiac disease. We sought to examine psychological symptoms in youngsters with medically unexplained chest pain. We hypothesized that children and adolescents with medically unexplained chest pain would have high rates of anxiety and depressive symptoms. We assessed 65 youngsters with noncardiac chest pain (NCCP) and 45 comparison youngsters with benign heart murmurs using self-report measures of anxiety and depressive symptoms and anxiety sensitivity. Compared with the asymptomatic benign-murmur group, youngsters with NCCP had higher levels of some anxiety symptoms and anxiety sensitivity. Differences on depressive symptoms were not significant. Though preliminary, results suggest that youngsters with chest pain may experience increased levels of some psychological symptoms. Future studies of noncardiac chest pain in youngsters should include larger samples and comprehensive diagnostic assessments as well as long-term follow-up evaluations.

To assess the cost-effectiveness of cardiac CT compared with exercise stress testing (EST) in improving the health-related quality of life of patients with stable chest pain. A cost-utility analysis alongside a single-centre randomised controlled trial carried out in Northern Ireland. Patients with stable chest pain were randomised to undergo either cardiac CT assessment or EST (standard care). The main outcome measure was cost per quality adjusted life year (QALY) gained at 1 year. Of the 500 patients recruited, 250 were randomised to cardiac CT and 250 were randomised to EST. Cardiac CT was the dominant strategy as it was both less costly (incremental total costs -£50.45; 95% CI -£672.26 to £571.36) and more effective (incremental QALYs 0.02; 95% CI -0.02 to 0.05) than EST. At a willingness-to-pay threshold of £20 000 per QALY the probability of cardiac CT being cost-effective was 83%. Subgroup analyses indicated that cardiac CT appears to be most cost-effective in patients with a likelihood of coronary artery disease (CAD) of <30%, followed by 30%-60% and then >60%. Cardiac CT is cost-effective compared with EST and cost-effectiveness was observed to vary with likelihood of CAD. This finding could have major implications for how patients with chest pain in the UK are assessed, however it would need to be validated in other healthcare systems. (ISRCTN52480460); results.

Among intermediate- to high-risk patients with chest pain, we have shown that a cardiac magnetic resonance (CMR) stress test strategy implemented in an observation unit (OU) reduces 1-year health care costs compared with inpatient care. In this study, we compare 2 OU strategies to determine among lower-risk patients if a mandatory CMR stress test strategy was more effective than a physicians' ability to select a stress test modality. On emergency department arrival and referral to the OU for management of low- to intermediate-risk chest pain, 120 individuals were randomly assigned to receive (1) a CMR stress imaging test (n=60) or (2) a provider-selected stress test (n=60: stress echo [62%], CMR [32%], cardiac catheterization [3%], nuclear [2%], and coronary CT [2%]). No differences were detected in length of stay (median CMR=24.2 hours versus 23.8 hours, P=0.75), catheterization without revascularization (CMR=0% versus 3%), appropriateness of admission decisions (CMR 87% versus 93%, P=0.36), or 30-day acute coronary syndrome (both 3%). Median cost was higher among those randomly assigned to the CMR-mandated group ($2005 versus $1686, P<0.001). In patients with lower-risk chest pain receiving emergency department-directed OU care, the ability of a physician to select a cardiac stress imaging modality (including echocardiography, CMR, or radionuclide testing) was more cost-effective than a pathway that mandates a CMR stress test. Contrary to prior observations in individuals with intermediate- to high-risk chest pain, in those with lower-risk chest pain, these results highlight the importance of physician-related choices during acute coronary syndrome diagnostic protocols.

Risk of acute coronary events in patients with methamphetamine and cocaine intoxication has been described. Little is known about the need for additional evaluation in these patients who do not have evidence of myocardial infarction after the initial emergency department evaluation. We herein describe our experience with these patients in a chest pain unit (CPU) and the rate of cardiac-related chest pain in this group. Retrospective analysis of patients evaluated in our CPU from January 1, 2000 to December 16, 2004 with a history of chest pain. Patients who had a positive urine toxicologic screen for methamphetamine or cocaine were included. No patients had ECG or cardiac injury marker evidence of myocardial infarction or ischemia during the initial emergency department evaluation. A diagnosis of cardiac-related chest pain was based upon positive diagnostic testing (exercise stress testing, nuclear perfusion imaging, stress echocardiography, or coronary artery stenosis >70%). During the study period, 4568 patients were evaluated in the CPU. A total of 1690 (37%) of patients admitted to the CPU underwent urine toxicologic testing. The result of urine toxicologic test was positive for cocaine or methamphetamine in 224 (5%). In the 2871 patients who underwent diagnostic testing for coronary artery disease (CAD), 401 (14%) were found to have positive results. There was no difference in the prevalence of CAD between those with positive result for toxicology screens (26/156, 17%) and those without (375/2715, 13%, RR 1.2, 95% CI 0.8-1.7). These findings suggest a relatively high rate of CAD in patients with methamphetamine and cocaine use evaluated in a CPU.

Although cardiac stress testing may help establish the safety of early discharge in patients with suspected acute coronary syndromes and negative troponins, more cost-effective strategies are necessary. We aimed to develop a clinical prediction rule to safely obviate the need for cardiac stress testing in this setting. A decision rule was derived in a prospective cohort of 3001 patients with acute chest pain and negative troponins, and validated in a set of 1473 subjects. The primary end point was a composite of positive cardiac stress testing (in the absence of a subsequent negative coronary angiogram), positive coronary angiography, or any major coronary events within 3 months. A score chart was built based on 7 variables: male sex (+2), age (+1 per decade from the fifth decade), diabetes mellitus (+2), hypercholesterolemia (+1), prior coronary revascularization (+2), type of chest pain (typical angina, +5; non-specific chest pain, -3), and non-diagnostic repolarization abnormalities (+2). In the validation set, the model showed good discrimination (c statistic = 0.84; 95% confidence interval, 0.82-0.87) and calibration (Hosmer-Lemeshow goodness-of-fit test, P= .34). If stress tests were avoided in patients in the validation sample with a sum score of 0 or lower, the number of referrals would be reduced by 23.4%, yielding a negative predictive value of 98.8% (95% confidence interval, 97.0%-99.7%). This novel prediction rule based on a combination of readily available clinical characteristics may be a valuable tool to decide whether stress testing can be reliably avoided in patients with acute chest pain and negative troponins.

Radiologic evaluation of acute chest pain--suspected myocardial ischemia.

PubMed

Stanford, William

2007-08-15

The American College of Radiology has developed appropriateness criteria for a number of clinical conditions and procedures. Criteria are available on imaging tests used in the evaluation of acute chest pain--suspected myocardial ischemia. Imaging tests for a suspected cardiac etiology include transthoracic echocardiography, transesophageal echocardiography, radionuclide perfusion imaging, radionuclide ventriculography, radionuclide infarct avid imaging, and positron emission tomography. If the cardiac ischemic work-up is negative or indeterminate, applicable tests include chest radiography; conventional, multidetector, and electron beam computed tomography; and magnetic resonance imaging. A summary of the criteria, with the advantages and limitations of each test, is presented in this article.

Using a Standardized Clinical Assessment and Management Plan (SCAMP) for pediatric patients presenting to clinic with chest pain, we evaluated the cost impact associated with implementation of the care algorithm. Prior to introduction of the SCAMP, we analyzed charges for 406 patients with chest pain, seen in 2009, and predicted 21% reduction of overall charges had the SCAMP methodology been used. The SCAMP recommended an echocardiogram for history, examination, or ECG findings suggestive of a cardiac etiology for chest pain. Resource utilization was reviewed for 1517 patients (7-21 years) enrolled in the SCAMP from July 2010 to April 2014. Compared to the 2009 historic cohort, patients evaluated by the SCAMP had higher rates of exertional chest pain (45% vs 37%) and positive family history (5% vs 1%). The SCAMP cohort had fewer abnormal physical examination findings (1% vs 6%) and abnormal electrocardiograms (3% vs 5%). Echocardiogram use increased in the SCAMP cohort compared to the 2009 historic cohort (45% vs 41%), whereas all other ancillary testing was reduced: exercise stress testing (4% SCAMP vs 28% historic), Holter (4% vs 7%), event monitors (3% vs 10%), and MRI (1% vs 2%). Total charges were reduced by 22% ($822 625) by use of the Chest Pain SCAMP, despite a higher percentage of patients for whom echocardiogram was recommended compared to the historic cohort. The Chest Pain SCAMP effectively streamlines cardiac testing and reduces resource utilization. Further reductions can be made by algorithm refinement regarding echocardiograms for exertional symptoms. © 2017 Wiley Periodicals, Inc.

Patients with chest pain contribute substantially to emergency department attendances, lengthy hospital stay, and inpatient admissions. A reliable, reproducible, and fast process to identify patients presenting with chest pain who have a low short-term risk of a major adverse cardiac event is needed to facilitate early discharge. We aimed to prospectively validate the safety of a predefined 2-h accelerated diagnostic protocol (ADP) to assess patients presenting to the emergency department with chest pain symptoms suggestive of acute coronary syndrome. This observational study was undertaken in 14 emergency departments in nine countries in the Asia-Pacific region, in patients aged 18 years and older with at least 5 min of chest pain. The ADP included use of a structured pre-test probability scoring method (Thrombolysis in Myocardial Infarction [TIMI] score), electrocardiograph, and point-of-care biomarker panel of troponin, creatine kinase MB, and myoglobin. The primary endpoint was major adverse cardiac events within 30 days after initial presentation (including initial hospital attendance). This trial is registered with the Australia-New Zealand Clinical Trials Registry, number ACTRN12609000283279. 3582 consecutive patients were recruited and completed 30-day follow-up. 421 (11.8%) patients had a major adverse cardiac event. The ADP classified 352 (9.8%) patients as low risk and potentially suitable for early discharge. A major adverse cardiac event occurred in three (0.9%) of these patients, giving the ADP a sensitivity of 99.3% (95% CI 97.9-99.8), a negative predictive value of 99.1% (97.3-99.8), and a specificity of 11.0% (10.0-12.2). This novel ADP identifies patients at very low risk of a short-term major adverse cardiac event who might be suitable for early discharge. Such an approach could be used to decrease the overall observation periods and admissions for chest pain. The components needed for the implementation of this strategy are widely available. The ADP has the potential to affect health-service delivery worldwide.

we examined the diagnostic performance of high sensitivity cardiac troponin T (cTnThs) measurement and its ability to predict risk in unselected patients presenting to the emergency department with acute chest pain. we conducted a retrospective analysis of 137 consecutive patients with chest pain (age range, 66 ± 16 years; 64% male). A final diagnosis of acute myocardial infarction was made using the "old" (cTnT fourth-generation assay, ≥ 0.04 microg/L) or the "new" cutpoint (cTnThs ≥ 0.014 microg/L). the adjudicated final diagnosis of acute myocardial infarction significantly increased from 20 to 35 patients (a 75% increase) and troponin-positive nonvascular cardiac chest pain from 10 to 30 (a 200% increase) using cTnThs. The number of patients with unstable angina or troponin-negative nonvascular cardiac chest pain significantly decreased (P <.05). Diagnostic performance of cTnThs levels at admission was significantly higher compared to cTnT levels (area under the curve [AUC] 0.85 vs AUC 0.70; P <.05). cTnThs levels below the detection limit (<0.003 microg/L) had a negative predictive value of 100% to exclude acute myocardial infarction. The event rate during 6 months of follow-up was low in patients with cTnThs levels <0.014 microg/L, while patients with cTnT levels ≥ 0.04 μg/L were at increased, and patients with cTnThs ≥ 0.014 μg/L and cTnT <0.04 microg/L at intermediate risk of death or recurrent myocardial infarction (P = .002). Risk was highest in chest pain patients with dynamic changes of cTnThs levels >30%. the introduction of cTnThs assay displays an excellent diagnostic performance for the workup of patients with chest pain at the time of their initial presentation. Even small increases of cTnThs indicate increased risk for death or myocardial infarction during follow-up. © 2010 Elsevier Inc. All rights reserved.

Emergency physicians can feel pressured by opposing forces of clinical reality and the need to publish successful key performance indicators in an environment of increasing demands and cost containment. This is particularly relevant to management of patients with undifferentiated chest pain and possible acute coronary syndrome. Unreliability of clinical assessment and high risk of adverse outcomes for all concerned exist, yet national guidelines are at odds with efforts to reduce ED crowding and access block. We report findings from the Nambour Short Low-Intermediate Chest pain risk trial, which safely introduced an accelerated diagnostic protocol with reduced ED length of stay and high patient acceptability. Over a 7-month period, there were no major adverse cardiac events by 30 days in 19% of undifferentiated chest pain presentations with possible acute coronary syndrome discharged after normal sensitive cardiac troponin taken 2 h after presentation and scheduled to return for outpatient exercise stress test. © 2013 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Low triiodothyronine (T3) levels and subclinical myocardial injury may be associated with adverse cardiac and cerebrovascular (CCV) events in individuals without clinically apparent coronary heart disease (CHD). The aim of this study was to determine the associations of a low T3 level and subclinical myocardial injury with the development of adverse CCV events in individuals without clinically apparent CHD. T3 and high-sensitivity cardiac troponin T (hs-cTnT) levels were analyzed in 250 patients with chest pain free of CHD and heart failure. The primary end point was the composite of sudden cardiac death, ischemic stroke, newly developed atrial fibrillation, pericardial effusion and thrombosis. Throughout a mean follow-up of 15.6 months, the primary end point happened in 17 patients (6.8%). Kaplan-Meier analysis disclosed a notably higher overall occurrence rate in patients with hs-cTnT levels ≥0.014 ng/mL and in patients with T3 <60 ng/dL. An exaggerated hazard was observed in patients with combined high hs-cTnT and low T3 levels. After adjustment, the hazard ratio for overall events in patients with high hs-cTnT/low T3 versus normal hs-cTnT/T3 was 11.72 (95% confidence interval, 2.83-48.57; P = 0.001). In patients with chest pain without clinically obvious CHD, high hs-cTnT combined with low T3 was associated with adverse cardiac/CCV events and was an independent predictor of overall events even after adjustment. These data suggest the importance of systemic factors, such as low T3 syndrome, in the development of adverse cardiac/CCV events beyond advancing clinical atherosclerotic coronary disease in patients with chest pain.

Troponin is considered a primary biomarker for coronary heart disease. We investigated the clinical utility of the Abbott high-sensitivity cardiac troponin I (hs-TnI) assay in patients with various cardiac problems. Precision was investigated by ten levels of pooled sera and three levels of control materials. We determined Abbott hs-TnI levels in a total of 3314 Korean patients with chest pain, including acute myocardial infarction (n=381), unstable angina (n=327), stable angina (n=1361), variant angina (n=189), non-coronary artery diseases (n=236), and nonspecific chest pain (n=820). The 99(th) percentile cutoff was established by the plasma from the cardio-healthy subgroup and validated by 118 healthy individuals. The total coefficient of variation in patient pooled sera and controls ranged from 3.93-6.35% and 4.81-9.73%, respectively. There was a significant difference in hs-TnI among various cardiac problems: subjects with non-cardiac chest pain (median 1.7 pg/mL, 25%/75% quartile 1.1/2.8 pg/mL), variant angina (2.4 pg/mL,1.4/5.6 pg/mL), stable angina (3.7 pg/mL, 2.1/8.9 pg/mL), unstable angina (10.7 pg/mL, 3.7/61.7 pg/mL), and non-coronary artery diseases (9.3 pg/mL, 4.3/37.4 pg/mL). However, the median levels of hs-TnI were not statistically different (p=0.921) between unstable angina and non-coronary artery diseases. The overall 99(th) percentile cutoff was 19.3 pg/mL (range 0.2-30.6 pg/mL). This new hs-TnI assay may be helpful in determining a differential diagnosis in patients with chest pain. © 2015 by the Association of Clinical Scientists, Inc.

Arterial hypertension is often associated with a stiff aorta as a result of collagen accumulation in the aortic wall and may produce chest pain. In the present study, possible interrelationships between aortic function, collagen turnover and exercise-induced chest pain in patients with arterial hypertension and angiographically normal coronary arteries were investigated. Ninety-seven patients with arterial hypertension, angiographically normal coronary arteries and no evidence of myocardial ischemia on nuclear cardiac imaging during exercise test were studied. Of these, 43 developed chest pain during exercise (chest pain group) while 54 did not (no chest pain group). Carotid femoral pulse-wave velocity (PWVc-f) was used to assess the elastic properties of the aorta. Amino-terminal pro-peptides of pro-collagen type I, (PINP, reflecting collagen synthesis), serum telopeptides of collagen type I (CITP, reflecting collagen degradation), pro-metalloproteinase 1 (ProMMP-1), and tissue inhibitor of metalloproteinase 1 (TIMP-1, related to collagen turnover) were measured in plasma by immunoassay. The chest pain group had higher PWVc-f, higher and /CITP ratio, and lower proMMP-1/ TIMP-1 ratio compared to the no chest pain group. PWVc-f (t=2.53, p=0.02) and PINP (t=2.42, p=0.02) were independently associated with the presence of chest pain in multiple regression analysis. Patients with arterial hypertension, exercise-induced chest pain and angiographically normal coronary arteries, without evidence of exercise-induced myocardial ischemia, had a stiffer aorta compared to those without chest pain. Alterations in collagen type I turnover that favor collagen accumulation in the aortic wall may contribute to aortic stiffening and chest pain in these patients.

The aim of this study was to compare the frequency of precordialgia between chagasic and non-chagasic women. A cross-sectional study comprised 647 female aged > or = 40, chagasic (n = 362) and controls (n = 285) was done at a Brazilian university hospital. Chagasic were classified as cardiac (n = 179), megas (n = 58) or indeterminate (n = 125) clinical forms. Chest pain was ascertained by typical or atypical retrosternal pain. Age (57.0 +/- 11.3 vs 57.3 +/- 10.4 years), and percentage of white women (75.8% vs 77.1%) were similar between chagasic and controls, respectively. Chest pain was more prevalent (p < 0.01) among chagasic (14.6%) than controls (5.6%), mainly in the cardiac form (relative risk = 2.41; range: 1.38-4.23), a phenomenon possibly related to cardiac parasympathetic denervation and myocardial microvascular changes.

We present the case of a 63-year-old woman with a remote history of supraventricular tachycardia and hyperlipidemia, who presented with recurrent episodes of acute-onset chest pain. An electrocardiogram showed no evidence of acute coronary syndrome. A chest radiograph revealed a prominent right-sided heart border. A suspected congenital pericardial cyst was identified on a computed tomographic chest scan, and stranding was noted around the cyst. The patient was treated with nonsteroidal anti-inflammatory drugs, and the pain initially abated. Another flare-up was treated similarly. Cardiac magnetic resonance imaging was then performed after symptoms had resolved, and no evidence of the cyst was seen. The suspected cause of the patient's chest pain was acute inflammation of a congenital pericardial cyst with subsequent rupture and resolution of symptoms.

Chest pain and acute dyspnoea are frequent causes of emergency medical services activation. The pre-hospital management of these conditions is heterogeneous across different regions of the world and Europe, as a consequence of the variety of emergency medical services and absence of specific practical guidelines. This position paper focuses on the practical aspects of the pre-hospital treatment on board and transfer of patients taken in charge by emergency medical services for chest pain and dyspnoea of suspected cardiac aetiology after the initial assessment and diagnostic work-up. The objective of the paper is to provide guidance, based on evidence, where available, or on experts' opinions, for all emergency medical services' health providers involved in the pre-hospital management of acute cardiovascular care. © The European Society of Cardiology 2015.

Congenital Complete Absence of Pericardium Masquerading as Pulmonary Embolism

Tariq, Saad; Mahmood, Sultan; Madeira, Samuel; Tarasov, Ethan

2013-01-01

Congenital absence of the pericardium is a rare cardiac condition, which can be either isolated or associated with other cardiac and extracardiac anomalies. There are six different types, depending on the severity of the involvement. Most of the patients with this defect are asymptomatic, especially the ones with complete absence of the pericardium. However, some patients are symptomatic, reporting symptoms that include chest pain, palpitations, dyspnea, and syncope. Diagnosis is established by the characteristic features on chest X-ray, echocardiogram, chest computed tomography (CT), and/or cardiac magnetic resonance imging (MRI). We present here a case of a 23 year-old-male, who presented to our hospital with complaints of pleuritic chest pain and exertional dyspnea, of a two-week duration. He was physically active and his past history was otherwise insignificant. His chest CT with contrast was interpreted as showing evidence of multiple emboli, predominantly in the left lung, and he was started on a heparin and warfarin therapy. A repeat chest CT with contrast three weeks later showed no significant change from the previous CT scan. Both scans showed that the heart was abnormally rotated to the left side of the chest. An echocardiogram raised the suspicion of congenital absence of the pericardium, with a posteriorly displaced heart. In retrospect, motion artifact on the left lung, attributed to cardiac pulsations and the lack of pericardium, resulted in a CT chest appearance, mimicking findings of pulmonary embolism. The misdiagnosis of pulmonary embolism was attributed to the artifact caused by excessive cardiac motion artifact on the chest CT scan. In non-gated CT angiograms, excessive motion causes an artifact that blurs the pulmonary vessels, reminiscent of a ′seagull′ or a ′boomerang′. Physicians need to be aware of this phenomenon, as well as the characteristic radiological features of this congenital anomaly, to enable them to make a correct diagnosis. PMID:23580923

The Role of Echocardiography in Coronary Artery Disease and Acute Myocardial Infarction

2013-01-01

Echocardiography is a non-invasive diagnostic technique which provides information regarding cardiac function and hemodynamics. It is the most frequently used cardiovascular diagnostic test after electrocardiography and chest X-ray. However, in a patient with acute chest pain, Transthoracic Echocardiography is essential both for diagnosing acute coronary syndrome, zeroing on the evaluation of ventricular function and the presence of regional wall motion abnormalities, and for ruling out other etiologies of acute chest pain or dyspnea, including aortic dissection and pericardial effusion. Echocardiography is a versatile imaging modality for the management of patients with chest pain and assessment of left ventricular systolic function, diastolic function, and even myocardial and coronary perfusion and is, therefore, useful in the diagnosis and triage of patients with acute chest pain or dyspnea. This review has focused on the current applications of echocardiography in patients with coronary artery disease and myocardial infarction. PMID:23646042

Specialized chest pain units (CPU) appear to increase the proportion of patients with acute chest pain who are properly evaluated. The aim of this study was to evaluate the survival and occurrence of cardiovascular events in patients without diagnosis at the end of the management of chest pain with high-sensibility troponin elevation. All consecutive patients who came to the cardiac emergency room of Poitiers University Hospital between January 1, 2014 and August 7, 2015 for chest pain and troponin elevation were included. The primary endpoint was the number of undiagnosed patients, and secondary endpoints included survival and major adverse cardiac event (MACE) occurrence in this population. A total of 1001 patients (695 male, mean age 68 ± 16 years) who had chest pain and troponin elevation were included. Median follow-up was 24.5 [14.7; 29.5] months. Forty-seven (4.7%) patients remained without diagnosis. Compared with patients with diagnosis, these patients were younger (53.6 ± 19.7 years, p<0.0001), had less hypertension (29.8%, p<0.0001), less diabetes (4.3%, p=0.0016) and less history of coronary artery disease (CAD) (6.4%, p<0.0001). Their GRACE score was lower (109.3 ± 33.3, p=0.002). None of the followed patients died or had MACE in six months of follow-up. Survival curves showed that the probability of survival was excellent not only at 6 months but also at 36 months (p=0.0025). Fewer than 5% of patients referred for chest pain and with high-sensitivity troponin elevation remained without diagnosis after adapted care in the CPU. Their 6-month prognosis was excellent.

To determine the incidence of clinical, cardiac-related endpoints and mortality among patients presenting to an emergency or cardiology department with non-specific chest pain (NSCP), and who receive testing with a high-sensitivity troponin. A second objective was to identify risk factors for the above-noted endpoints during 12 months of follow-up. A prospective multicentre study. Emergency and cardiology departments in Southern Denmark. The study enrolled 1027 patients who were assessed for acute chest pain in an emergency or cardiology department, and in whom a myocardial infarction or another obvious reason for chest pain had been ruled out. Patients were enrolled from September 2014 to June 2015 and followed for 1 year. Clinical, cardiac-related endpoints (cardiac-related death, acute myocardial infarction, unstable angina and coronary revascularisation) and all-cause mortality. Over a period of 1 year, cardiac-related endpoints were found in 19 patients (1.9%): 0 patients experienced cardiac-related death, 2 (0.2%) had myocardial infarction, 4 (0.4%) had unstable angina pectoris and 17 (1.7%) underwent coronary revascularisation. All-cause mortality was observed in seven patients (0.7%). When compared with the general population, the standardised mortality ratio did not differ. The risk factors associated with the study endpoints included male gender, body mass index >25 kg/m 2 , previous known coronary artery disease, hypertension, hypercholesterolaemia, diabetes mellitus and the use of statins. A total of 73% of the endpoints occurred in males. The prognosis for patients with NSCP is favourable, with a 1-year mortality after discharge that is comparable with the background population. Few clinical endpoints took place during follow-up, and those that did were predominantly in males. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

462 patients presenting with chest pain to a rural district general hospital underwent calcium scoring and pretest clinical risk assessment in order to stratify subsequent investigations and treatment was retrospectively reviewed. The patients were followed up for two years and further investigations and outcomes recorded. Of the 206 patients with zero calcium score, 132 patients were immediately discharged from cardiac follow-up with no further investigation on the basis of their calcium score, low pretest risk of coronary artery disease, and no significant incidental findings. After further tests, 267 patients were discharged with no further cardiac therapy, 88 patients were discharged with additional medical therapy, and 19 patients underwent coronary artery by-pass grafting or percutaneous intervention. 164 patients with incidental findings on the chest CT (computed tomography) accompanying calcium scoring were reviewed, of which 88 patients underwent further tests and follow-up for noncardiac causes of chest pain. The correlations between all major risk factors and calcium scores were weak except for a combination of diabetes and hypertension in the male gender (P = 0.012), The use of calcium scoring and pretest risk appeared to reduce the number of unnecessary cardiac investigations in our patients: however, the calcium scoring test produced a high number of incidental findings on the associated CT scans.

A Review of Esophageal Chest Pain

2015-01-01

Noncardiac chest pain is a term that encompasses all causes of chest pain after a cardiac source has been excluded. This article focuses on esophageal sources for chest pain. Esophageal chest pain (ECP) is common, affects quality of life, and carries a substantial health care burden. The lack of a systematic approach toward the diagnosis and treatment of ECP has led to significant disability and increased health care costs for this condition. Identifying the underlying cause(s) or mechanism(s) for chest pain is key for its successful management. Common etiologies include gastroesophageal reflux disease, esophageal hypersensitivity, dysmotility, and psychological conditions, including panic disorder and anxiety. However, the pathophysiology of this condition is not yet fully understood. Randomized controlled trials have shown that proton pump inhibitor therapy (either omeprazole, lansoprazole, or rabeprazole) can be effective. Evidence for the use of antidepressants and the adenosine receptor antagonist theophylline is fair. Psychological treatments, notably cognitive behavioral therapy, may be useful in select patients. Surgery is not recommended. There remains a large unmet need for identifying the phenotype and prevalence of pathophysiologic mechanisms of ECP as well as for well-designed multicenter clinical trials of current and novel therapies.

A cardiologist's evaluation of psychiatric symptoms in patients with chest pain is rare. This study aimed to determine the psychiatric characteristics of patients with and without coronary artery disease (CAD) and explore their relationship with the intensity of chest pain. Out of 139 consecutive patients referred to the cardiology outpatient department, 31 with atypical chest pain (heartburn, acid regurgitation, dyspnea, and palpitation) were excluded and 108 were enrolled for the present study. The enrolled patients underwent complete numerical rating scale of chest pain and the symptom checklist for minor psychiatric disorders at the time of first outpatient visit. The non-CAD group consisted of patients with a normal stress test, coronary computed tomography angiogram, or coronary angiogram, and the CAD group included those with an abnormal coronary angiogram. Nineteen patients (17.6%) were diagnosed with CAD. No differences in the psychiatric characteristics were observed between the groups. "Feeling tense", "self-reproach", and "trouble falling asleep" were more frequently observed in the non-CAD (p=0.007; p=0.046; p=0.044) group. In a multiple linear regression analysis with a stepwise selection, somatization without chest pain in the non-CAD group and hypochondriasis in the CAD group were linearly associated with the intensity of chest pain (β=0.108, R(2)=0.092, p=0.004; β= -0.525, R(2)=0.290, p=0.010). No differences in psychiatric characteristics were observed between the groups. The intensity of chest pain was linearly associated with somatization without chest pain in the non-CAD group and inversely linearly associated with hypochondriasis in the CAD group.

Patients with panic disorder experience symptoms such as palpitations, chest pain, dizziness, and breathlessness. Consequently, they may attend the Emergency Department (ED) to be assessed for possible emergency medical conditions. Recognition of panic disorder within the ED is low. We sought to establish the prevalence of panic disorder in patients presenting for ED investigation of potential acute coronary syndrome. We also sought to characterise the cohort of patients with panic disorder in terms of presenting symptoms, risk factors, medical history and major adverse cardiac events (MACE). This was an observational study of 338 adult patients presenting to the Emergency Department of a tertiary hospital in Australia. Research nurses collected clinical data using a customised case report form. The outcome was panic disorder, assessed using the Mini International Neuropsychiatric Interview. The average age of participants was 50.2 years and 37.9% were female. Thirty-day MACE occurred in 7.7% of the cohort. The clinical diagnosis of panic disorder was made in 5.6% (95% CI: 3.4-8.6%) of patients. Compared to patients without panic disorder, patients with panic disorder were slightly more likely to report that their pain felt heavy (48.9% and 73.7% respectively, p=0.04). All other reported symptoms were similar in the two groups. The prevalence of panic disorder was low in patients presenting to an Australian ED with chest pain. Clinical signs or symptoms that are routinely collected as part of the chest pain workup cannot be used to distinguish patients with and without panic disorder.

A novel approach to cardiac troponins to improve the diagnostic work-up in chest pain patients.

PubMed

Eggers, Kai M; Jaffe, Allan S; Svennblad, Bodil; Lindahl, Bertil

2012-12-01

In patients with acute chest pain, current guidelines recommend serial measurements of cardiac troponins at predefined and partly late time points. Consequently, diagnostic assessment in these patients tends to be lengthy and often results in unnecessary admissions. We, therefore, evaluated whether an approach integrating troponin results into the clinical context provided by the individual patient's presentation might facilitate the early diagnostic work-up. In 197 chest pain patients, cardiac troponin I (cTnI; Stratus CS) was measured serially within 12 hours after hospital admission. In patient cohorts with different chances of having myocardial infarction (MI) according to clinical data, electrocardiographic findings, and admission biomarker results, pretest probabilities for MI were calculated and compared with posttest probabilities derived from subsequent cTnI results after admission. Elevated cTnI levels at 1 to 2 hours after admission revealed ≥95.0% posttest probabilities for MI in cohorts with intermediate or high chances of having MI. The posttest probabilities for the absence of MI were 94.7% to 98.2% in cohorts with low or intermediate chances of having MI when cTnI was negative at 2 hours. Troponin testing considering the individual patient's pretest probability of MI seems, in conclusion, to provide clinically useful information already 1 to 2 hours after admission. Such an approach has the potential to identify both patient cohorts in whom early discharge or admittance for further evaluation would be appropriate. This could facilitate the early diagnostic work-up of chest pain patients, thereby improving patient flow and reducing overcrowding in healthcare facilities.

Increasing numbers of octogenarians are being referred for investigation of chest pain. While dobutamine stress echocardiography (DSE) has been shown to be useful in younger patients, its role among octogenarians remains unclear. This investigation aimed to investigate the safety and prognostic benefits of DSE on cardiac events and total mortality in octogenarians. 550 consecutive patients aged ≥80 years underwent DSE for suspected cardiac chest pain. All subjects were followed-up prospectively until March 2011, and the study end-points were a major cardiac event and total mortality. One hundred and eighty-three (33%) patients had a positive DSE result, 271 (49%) had a normal study, and 164 (30%) had fixed-wall motion abnormalities. During a mean follow-up of 2.14±1.13 years, there were 217 (39%) cardiac events and 63 (11%) deaths, of which 46 (73%) were cardiac. The absolute risk of cardiac events increased with burden of ischaemia on DSE, from 13%/year (none), to 26%/year (1-3 ischaemic (LV) segments), and 38%/year (>3 ischaemic LV segments), p<0.001. Any ischaemia was associated with an additional 13 cardiac events per 100 person-years. In multivariate analysis, compared with non-ischaemic patients, the relative hazard of cardiac events for 1-3 and >3 ischaemic LV segments were 1.34 (95% CI 1.13 to 1.29) and 1.86 (95% CI 1.16 to 2.98), respectively. Addition of echocardiographic parameters to basic models improved the C statistic from 0.77 to 0.89 (p<0.001). Among octogenarians referred with suspected cardiac chest pain, DSE is safe and, importantly, identifies a subset at high risk of cardiac events. Published by the BMJ Publishing Group Limited.

Patients undergoing minimally invasive cardiac surgery have the potential for significant pain from the thoracotomy site. We report the successful use of pectoral nerve block types I and II (Pecs I and II) as rescue analgesia in a patient undergoing minimally invasive mitral valve repair. In this case, a 78-year-old man, with no history of chronic pain, underwent mitral valve repair via right anterior thoracotomy for severe mitral regurgitation. After extubation, he complained of 10/10 pain at the incision site that was minimally responsive to intravenous opioids. He required supplemental oxygen because of poor pulmonary mechanics, with shallow breathing and splinting due to pain, and subsequent intensive care unit readmission. Ultrasound-guided Pecs I and II blocks were performed on the right side with 30 mL of 0.2% ropivacaine with 1:400,000 epinephrine. The blocks resulted in near-complete chest wall analgesia and improved pulmonary mechanics for approximately 24 hours. After the single-injection blocks regressed, a second set of blocks was performed with 266 mg of liposomal bupivacaine mixed with bupivacaine. This second set of blocks provided extended analgesia for an additional 48 hours. The patient was weaned rapidly from supplemental oxygen after the blocks because of improved analgesia. Pectoral nerve blocks have been described in the setting of breast surgery to provide chest wall analgesia. We report the first successful use of Pecs blocks to provide effective chest wall analgesia for a patient undergoing minimally invasive cardiac surgery with thoracotomy. We believe that these blocks may provide an important nonopioid option for the management of pain during recovery from minimally invasive cardiac surgery.

Cardiac echinococcosis is a very rare disease, especially in girls. We report a case of interventricular septum echinococcosis. A 14-year-old girl was referred for chest pain. Magnetic resonance imaging and two-dimensional echocardiography revealed a cyst in the distal interventricular septum. We concluded that MR imaging is useful in diagnosis and planning of surgery. Cardiac hydatid cyst should be considered in the differential diagnosis of patients with anginalike pain in endemic areas.

The emergency department assessment of chest pain score accelerated diagnostic pathway (EDACS-ADP) facilitates low-risk ED chest pain patients early to outpatient investigation. We aimed to validate this rule in a North American population. We performed a retrospective validation of the EDACS-ADP using 763 chest pain patients who presented to St Paul's Hospital, Vancouver, Canada, between June 2000 and January 2003. Patients were classified as low risk if they had an EDACS <16, no new ischaemia on ECG and non-elevated serial 0-hour and 2-hour cardiac troponin concentrations. The primary outcome was the number of patients who had a predetermined major adverse cardiac event (MACE) at 30 days after presentation. Of the 763 patients, 317 (41.6%) were classified as low risk by the EDACS-ADP. The sensitivity, specificity, negative predictive value and positive predictive value of the EDACS-ADP for 30-day MACE were 100% (95% CI 94.2% to 100%), 46.4% (95% CI 42.6% to 50.2%), 100% (95% CI 98.5% to 100.0%) and 17.5% (95% CI 14.1% to 21.3%), respectively. This study validated the EDACS-ADP in a novel context and supports its safe use in a North American population. It confirms that EDACS-ADP can facilitate progression to early outpatient investigation in up to 40% of ED chest pain patients within 2 hours. Published by the BMJ Publishing Group Limited.

2013-05-01

In 2010, guidelines published by the National Institute for Clinical Excellence (NICE) suggested a change in the way patients with stable chest pain of suspected cardiac origin were investigated. These guidelines removed exercise treadmill testing from routine use and introduced cardiac CT to regular use. To investigate whether these guidelines had improved our service provision by reducing the number of further investigations required to make a diagnosis, and to see if our costs had increased now that the less expensive exercise treadmill tests were not recommended. Clinic letters were used to assess patients pretest likelihood of coronary artery disease for two six-month cohorts of consecutive patients seen in the rapid access chest pain clinic (January-June 2010 and July-December 2011) using NICE published methodology, and to ascertain which investigations patients had. Using NICE modelled costs, we generated comparative hypothetical costs for each cohort and an average cost per patient. In the January-June 2010 cohort, 435 patients with chest pain were seen, and in July-December 2011, 334 patients were seen. In the pre-NICE guidelines cohort, 23% of patients required two investigations as compared with 11.4% in the post-NICE guidelines cohort, with no patient requiring three investigations as compared with 3% in the original cohort. There was no significant increase in costs per patient in the post-NICE guidance group. Implementing NICE guidance reduced the number of investigations needed per patient, and did not prove more expensive for our department in the short term.

A 50-year-old male with a history of hemodialysis dependent chronic kidney disease presented to our emergency department with acute midsternal crushing chest pain. Patient was diagnosed with acute anterolateral wall Myocardial Infraction due to the presence of corresponding ST segment elevations in EKG and underwent emergent cardiac catheterization which revealed normal patent coronaries without any disease. He continued to have chest pain for which CT of the chest was done which revealed pneumomediastinum with mediastinal hematoma, due to the recent attempted thrombectomy for thrombus in his right brachiocephalic vein.

A study to derive a clinical decision rule for triage of emergency department patients with chest pain: design and methodology

PubMed Central

Hess, Erik P; Wells, George A; Jaffe, Allan; Stiell, Ian G

2008-01-01

Background Chest pain is the second most common chief complaint in North American emergency departments. Data from the U.S. suggest that 2.1% of patients with acute myocardial infarction and 2.3% of patients with unstable angina are misdiagnosed, with slightly higher rates reported in a recent Canadian study (4.6% and 6.4%, respectively). Information obtained from the history, 12-lead ECG, and a single set of cardiac enzymes is unable to identify patients who are safe for early discharge with sufficient sensitivity. The 2007 ACC/AHA guidelines for UA/NSTEMI do not identify patients at low risk for adverse cardiac events who can be safely discharged without provocative testing. As a result large numbers of low risk patients are triaged to chest pain observation units and undergo provocative testing, at significant cost to the healthcare system. Clinical decision rules use clinical findings (history, physical exam, test results) to suggest a diagnostic or therapeutic course of action. Currently no methodologically robust clinical decision rule identifies patients safe for early discharge. Methods/design The goal of this study is to derive a clinical decision rule which will allow emergency physicians to accurately identify patients with chest pain who are safe for early discharge. The study will utilize a prospective cohort design. Standardized clinical variables will be collected on all patients at least 25 years of age complaining of chest pain prior to provocative testing. Variables strongly associated with the composite outcome acute myocardial infarction, revascularization, or death will be further analyzed with multivariable analysis to derive the clinical rule. Specific aims are to: i) apply standardized clinical assessments to patients with chest pain, incorporating results of early cardiac testing; ii) determine the inter-observer reliability of the clinical information; iii) determine the statistical association between the clinical findings and the composite outcome; and iv) use multivariable analysis to derive a highly sensitive clinical decision rule to guide triage decisions. Discussion The study will derive a highly sensitive clinical decision rule to identify low risk patients safe for early discharge. This will improve patient care, lower healthcare costs, and enhance flow in our busy and overcrowded emergency departments. PMID:18254973

This investigation was designed to test the hypothesis that continuous cardiac imaging using an ultrasound transducer developed in our laboratory (ContiScan) is superior to electrocardiogram (ECG) monitoring in the diagnosis of coronary artery disease (CAD) in patients with acute non-ST segment elevation chest pain syndromes. Seventy patients with intermediate to high probability of CAD who presented with typical anginal chest pain and no evidence of ST segment elevation on the ECG were studied. The 2.5-MHz transducer is spherical in its distal part mounted in an external housing to permit steering in 360 degrees. The transducer was placed at the left sternal border to image the left ventricular short-axis view and recorded on video tape at baseline, during and after episodes of chest pain. Two ECG leads were continuously monitored. The presence of CAD was confirmed by coronary arteriography or nuclear or echocardiographic stress testing. Twenty-four patients had regional wall motion abnormalities (RWMA) on their initial echo which were unchanged during the period of monitoring. All had evidence of CAD. Twenty-eight patients had transient RWMA. All had evidence of CAD. Eighteen patients had normal wall motion throughout the monitoring period, 14 of these had no evidence of CAD, and four had evidence of CAD. These four patients did not have chest pain during monitoring. The sensitivity, specificity, and accuracy of echocardiographic monitoring for diagnosing non-ST elevation myocardial infarction was 88%, 100%, and 91% respectively. The sensitivity, specificity, and accuracy of the ECG for diagnosis of CAD were 31%, 100%, and 52%, respectively. Echocardiography was superior to ECG (P < 0.001). The data indicate that continuous cardiac imaging is superior to ECG monitoring for the diagnosis of CAD in patients presenting with acute non-ST segment elevation chest pain syndromes. This technique could be a useful adjunct to ECG monitoring for myocardial ischemia in the acute care setting. © 2012, Wiley Periodicals, Inc.

To validate an accelerated biomarker strategy using a high-sensitivity cardiac troponin T (hs-cTnT) assay for diagnosing acute myocardial infarction (AMI) in patients presenting to the emergency department with chest pain; and to validate this strategy in combination with the National Heart Foundation of Australia/Cardiac Society of Australia and New Zealand risk stratification model. Single-centre, prospective, observational cohort study of 764 adults presenting to a tertiary hospital with symptoms of possible acute coronary syndrome between November 2008 and February 2011. AMI or cardiac death within 24 hours of presentation (primary), and major adverse cardiac events within 30 days (secondary). An elevated hs-cTnT assay result above the 99th percentile at either the 0 h or 2 h time points had sensitivity of 96.4% (95% CI, 87.9%-99.0%), specificity of 82.6% (95% CI, 79.7%-85.2%), negative predictive value of 99.7% (95% CI, 98.8%-99.9%) and positive predictive value of 30.5% (95% CI, 24.2%-37.6%) for diagnosing AMI. Compared with a traditional 6 h cardiac troponin testing strategy, the accelerated strategy led to reclassification of risk in only two patients with adverse cardiac outcomes, with no net effect on appropriate management. In patients presenting with chest pain, an accelerated biomarker strategy using the hs-cTnT assay performed well in the initial diagnosis of AMI. The accelerated strategy was also effective when incorporated into a comprehensive strategy of risk stratification that included clinical and demographic factors. The time saved by this approach could have a major impact on health service delivery. Australian New Zealand Clinical Trials Registry ACTRN12610000053022.

The establishment of chest pain units (CPUs) in the USA and UK has led to improvements in the prognosis of patients with chest pain and myocardial infarction, optimizing access to specialized diagnostic and therapeutic facilities and reducing costs. To establish a uniform implementation of this type of service in Germany, the German Cardiac Society (DGK) founded a 'CPU task force' in 2007, which developed a set of standard requirements and a nationwide certification programme. The recommendations for minimum standard requirements were published in 2008. As of November 2011, 132 CPUs were certified and 36 units were in the certification process. The aim of the DGK is to certify as many as 250 centres (units) throughout Germany within the next 2 years, to provide nationwide coverage. Applications from Switzerland are also being filed. Public awareness campaigns in cooperation with national league soccer teams were organized to raise awareness of the importance for early diagnosis and treatment of cardiac diseases and to publicize the existence of these new facilities. The German model of CPU certification allows nationwide and prospectively European-wide standardization of patient care and to improve adherence to international guidelines. Coupled with awareness campaigns and with the launch of a German CPU Registry, this process is aimed at improving the education and treatment of patients with chest pain and to provide scientific information about the quality of patient care.

Most patients presenting to US Emergency Departments (ED) with chest pain are hospitalized for comprehensive testing. These evaluations cost the US health system >$10 billion annually, but have a diagnostic yield for acute coronary syndrome (ACS) of <10%. The history/ECG/age/risk factors/troponin (HEART) Pathway is an accelerated diagnostic protocol (ADP), designed to improve care for patients with acute chest pain by identifying patients for early ED discharge. Prior efficacy studies demonstrate that the HEART Pathway safely reduces cardiac testing, while maintaining an acceptably low adverse event rate. The purpose of this study is to determine the effectiveness of HEART Pathway ADP implementation within a health system. This controlled before-after study will accrue adult patients with acute chest pain, but without ST-segment elevation myocardial infarction on electrocardiogram for two years and is expected to include approximately 10,000 patients. Outcomes measures include hospitalization rate, objective cardiac testing rates (stress testing and angiography), length of stay, and rates of recurrent cardiac care for participants. In pilot data, the HEART Pathway decreased hospitalizations by 21%, decreased hospital length (median of 12 hour reduction), without increasing adverse events or recurrent care. At the writing of this paper, data has been collected on >5000 patient encounters. The HEART Pathway has been fully integrated into health system electronic medical records, providing real-time decision support to our providers. We hypothesize that the HEART Pathway will safely reduce healthcare utilization. This study could provide a model for delivering high-value care to the 8-10 million US ED patients with acute chest pain each year.

Erectile dysfunction (ED) is a frequent complaint of elderly subjects and is closely associated with endothelial dysfunction and cardiovascular disease (CVD). Uric acid is also associated with endothelial dysfunction, oxidative stress, and CVD, raising the hypothesis that an increased serum uric acid might predict ED in patients who are at risk for coronary artery disease (CAD). This study aims to evaluate the association of serum uric acid levels with presence and severity of ED in patients presenting with chest pain of presumed cardiac origin. This is a cross-sectional study of 312 adult male patients with suspected CAD who underwent exercise stress test (EST) for workup of chest pain and completed a sexual health inventory for men survey form to determine the presence and severity of ED. Routine serum biochemistry (and uric acid levels) were measured. Logistic regression analysis was used to assess risk factors for ED. The short version of the International Index of Erectile Function questionnaire diagnosed ED (cutoff score ≤ 21). Serum uric acid levels were determined. Patients with chest pain of suspected cardiac origin underwent an EST. One hundred forty-nine of 312 (47.7%) male subjects had ED by survey criteria. Patients with ED were older and had more frequent CAD, hypertension, diabetes and impaired renal function, and also had significantly higher levels of uric acid, fibrinogen, glucose, C-reactive protein, triglycerides compared with patients without ED. Uric acid levels were associated with ED by univariate analysis (odds ratio = 1.36, P = 0.002); however, this association was not observed in multivariate analysis adjusted for estimated glomerular filtration rate. Subjects presenting with chest pain of presumed cardiac origin are more likely to have ED if they have elevated uric acid levels. © 2013 International Society for Sexual Medicine.

The optimal imaging strategy for patients with stable chest pain is uncertain. To determine the cost-effectiveness of different imaging strategies for patients with stable chest pain. Microsimulation state-transition model. Published literature. 60-year-old patients with a low to intermediate probability of coronary artery disease (CAD). Lifetime. The United States, the United Kingdom, and the Netherlands. Coronary computed tomography (CT) angiography, cardiac stress magnetic resonance imaging, stress single-photon emission CT, and stress echocardiography. Lifetime costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios. The strategy that maximized QALYs and was cost-effective in the United States and the Netherlands began with coronary CT angiography, continued with cardiac stress imaging if angiography found at least 50% stenosis in at least 1 coronary artery, and ended with catheter-based coronary angiography if stress imaging induced ischemia of any severity. For U.K. men, the preferred strategy was optimal medical therapy without catheter-based coronary angiography if coronary CT angiography found only moderate CAD or stress imaging induced only mild ischemia. In these strategies, stress echocardiography was consistently more effective and less expensive than other stress imaging tests. For U.K. women, the optimal strategy was stress echocardiography followed by catheter-based coronary angiography if echocardiography induced mild or moderate ischemia. Results were sensitive to changes in the probability of CAD and assumptions about false-positive results. All cardiac stress imaging tests were assumed to be available. Exercise electrocardiography was included only in a sensitivity analysis. Differences in QALYs among strategies were small. Coronary CT angiography is a cost-effective triage test for 60-year-old patients who have nonacute chest pain and a low to intermediate probability of CAD. Erasmus University Medical Center.

The epidemiology of chest pain differs strongly between outpatient and emergency settings. In general practice, the most frequent cause is the chest wall pain. However, there is a lack of information about the characteristics of this syndrome. The aims of the study are to describe the clinical aspects of chest wall syndrome (CWS). Prospective, observational, cohort study of patients attending 58 private practices over a five-week period from March to May 2001 with undifferentiated chest pain. During a one-year follow-up, questionnaires including detailed history and physical exam, were filled out at initial consultation, 3 and 12 months. The outcomes were: clinical characteristics associated with the CWS diagnosis and clinical evolution of the syndrome. Among 24 620 consultations, we observed 672 cases of chest pain and 300 (44.6%) patients had a diagnosis of chest wall syndrome. It affected all ages with a sex ratio of 1:1. History and sensibility to palpation were the keys for diagnosis. Pain was generally moderate, well localised, continuous or intermittent over a number of hours to days or weeks, and amplified by position or movement. The pain however, may be acute.

Background The epidemiology of chest pain differs strongly between outpatient and emergency settings. In general practice, the most frequent cause is the chest wall pain. However, there is a lack of information about the characteristics of this syndrome. The aims of the study are to describe the clinical aspects of chest wall syndrome (CWS). Methods Prospective, observational, cohort study of patients attending 58 private practices over a five-week period from March to May 2001 with undifferentiated chest pain. During a one-year follow-up, questionnaires including detailed history and physical exam, were filled out at initial consultation, 3 and 12 months. The outcomes were: clinical characteristics associated with the CWS diagnosis and clinical evolution of the syndrome. Results Among 24 620 consultations, we observed 672 cases of chest pain and 300 (44.6%) patients had a diagnosis of chest wall syndrome. It affected all ages with a sex ratio of 1:1. History and sensibility to palpation were the keys for diagnosis. Pain was generally moderate, well localised, continuous or intermittent over a number of hours to days or weeks, and amplified by position or movement. The pain however, may be acute. Eighty-eight patients were affected at several painful sites, and 210 patients at a single site, most frequently in the midline or a left-sided site. Pain was a cause of anxiety and cardiac concern, especially when acute. CWS coexisted with coronary disease in 19 and neoplasm in 6. Outcome at one year was favourable even though CWS recurred in half of patients. Conclusion CWS is common and benign, but leads to anxiety and recurred frequently. Because the majority of chest wall pain is left-sided, the possibility of coexistence with coronary disease needs careful consideration. PMID:17850647

How to Diagnose and Treat Functional Chest Pain.

PubMed

Remes-Troche, Jose M

2016-12-01

Chest pain that is not explained by reflux disease or cardiac, musculoskeletal, mucosal, or motor esophageal abnormalities is classified as functional chest pain (FCP). Although several mechanisms are involved, esophageal hypersensitivity plays a major role and it could be considered a biomarker for FCP. Psychologic comorbidity such as anxiety, neuroticism, depression, and somatization is common. When the diagnosis of FCP is suspected, patients should undergo evaluation with esophageal motility testing, endoscopy, 24-h esophageal pH monitoring, and in some cases, sensory tests. Once the diagnosis of FCP has been established, treatment options rely on controlling patients' symptoms. Medical treatment has focused predominantly on medications that target pain, such as antidepressants and other pain neuromodulators. Non-pharmacologic interventions with complementary behavioral treatments, such as cognitive behavioral therapy, biofeedback, and hypnosis, have recently been recognized as useful in FCP patients. The latest findings on the evaluation and treatment of FCP are outlined herein.

The management of low-risk patients presenting to emergency departments is a common and challenging clinical problem entailing 8 million emergency department visits annually. Although a majority of these patients do not have a life-threatening condition, the clinician must distinguish between those who require urgent treatment of a serious problem and those with more benign entities who do not require admission. Inadvertent discharge of patients with acute coronary syndrome from the emergency department is associated with increased mortality and liability, whereas inappropriate admission of patients without serious disease is neither indicated nor cost-effective. Clinical judgment and basic clinical tools (history, physical examination, and electrocardiogram) remain primary in meeting this challenge and affording early identification of low-risk patients with chest pain. Additionally, established and newer diagnostic methods have extended clinicians' diagnostic capacity in this setting. Low-risk patients presenting with chest pain are increasingly managed in chest pain units in which accelerated diagnostic protocols are performed, comprising serial electrocardiograms and cardiac injury markers to exclude acute coronary syndrome. Patients with negative findings usually complete the accelerated diagnostic protocol with a confirmatory test to exclude ischemia. This is typically an exercise treadmill test or a cardiac imaging study if the exercise treadmill test is not applicable. Rest myocardial perfusion imaging has assumed an important role in this setting. Computed tomography coronary angiography has also shown promise in this setting. A negative accelerated diagnostic protocol evaluation allows discharge, whereas patients with positive findings are admitted. This approach has been found to be safe, accurate, and cost-effective in low-risk patients presenting with chest pain.

To assess the presence of coronary artery disease (CAD) in women with atypical chest pain with low or intermediate risk for significant CAD by means of calcium scoring (CaSc) combined with coronary computed tomography angiography (CCTA) and to estimate the equivalent radiation dose in women. From December 2011 until July 2013, all consecutively performed cardiac CTs in women with atypical chest pain were included prospectively in the present study. Both CaSc and CCTA were obtained by a dual source flying focal spot 2×64 slice Somatom Definition Flash. Absence of CAD was defined as CaSc 0 and absence of noncalcified plaques. Presence of CAD was determined as CaSc>0 and/or presence of noncalcified plaques. The impact on patient management was also scored within our patient cohort. A total of 1033 procedures in 1014 women (mean age 59±10 years; mean BMI 26±8) were analyzed. In 520 (51%) women, CAD was absent. In 494 (49%) women, CAD was diagnosed, and in this subgroup the mean CaSc was 137±229. Thirty-seven (7%) of 494 women with CAD showed only noncalcified plaques. The mean equivalent radiation dose for the cardiac CTs of 1014 women was 2.2±1.6 mSv. Combined CaSc and CCTA excludes CAD in approximately 50% of women with atypical chest pain, and delivers a modest radiation dose of 2.2±1.6 mSv. CCTA has a substantial impact on patient management and can thus be advocated as first diagnostic tool in excluding CAD in women with atypical chest pain in terms of latest generation equipment with emphasize on radiation reduction techniques.

Patient history and physical examination are widely accepted as cornerstones of diagnosis in modern medicine. We aimed to assess the value of individual historical and examination findings for diagnosing acute myocardial infarction (AMI) and predicting adverse cardiac events in undifferentiated Emergency Department (ED) patients with chest pain. We prospectively recruited patients presenting to the ED with suspected cardiac chest pain. Clinical features were recorded using a custom-designed report form. All patients were followed up for the diagnosis of AMI and the occurrence of adverse events (death, AMI or urgent revascularization) within 6 months. AMI was diagnosed in 148 (18.6%) of the 796 patients recruited. Following adjustment for age, sex and ECG changes, the following characteristics made AMI more likely (adjusted odds ratio, 95% confidence intervals): pain radiating to the right arm (2.23, 1.24-4.00), both arms (2.69, 1.36-5.36), vomiting (3.50, 1.81-6.77), central chest pain (3.29, 1.94-5.61) and sweating observed (5.18, 3.02-8.86). Pain in the left anterior chest made AMI significantly less likely (0.25, 0.14-0.46). The presence of rest pain (0.67, 0.41-1.10) or pain radiating to the left arm (1.36, 0.89-2.09) did not significantly alter the probability of AMI. Our results challenge many widely held assertions about the value of individual symptoms and signs in ED patients with suspected acute coronary syndromes. Several 'atypical' symptoms actually render AMI more likely, whereas many 'typical' symptoms that are often considered to identify high-risk populations have no diagnostic value. Copyright 2009.

Objective We aimed to derive and validate a clinical decision rule (CDR) for suspected cardiac chest pain in the emergency department (ED). Incorporating information available at the time of first presentation, this CDR would effectively risk-stratify patients and immediately identify: (A) patients for whom hospitalisation may be safely avoided; and (B) high-risk patients, facilitating judicious use of resources. Methods In two sequential prospective observational cohort studies at heterogeneous centres, we included ED patients with suspected cardiac chest pain. We recorded clinical features and drew blood on arrival. The primary outcome was major adverse cardiac events (MACE) (death, prevalent or incident acute myocardial infarction, coronary revascularisation or new coronary stenosis >50%) within 30 days. The CDR was derived by logistic regression, considering reliable (κ>0.6) univariate predictors (p<0.05) for inclusion. Results In the derivation study (n=698) we derived a CDR including eight variables (high sensitivity troponin T; heart-type fatty acid binding protein; ECG ischaemia; diaphoresis observed; vomiting; pain radiation to right arm/shoulder; worsening angina; hypotension), which had a C-statistic of 0.95 (95% CI 0.93 to 0.97) implying near perfect diagnostic performance. On external validation (n=463) the CDR identified 27.0% of patients as ‘very low risk’ and potentially suitable for discharge from the ED. 0.0% of these patients had prevalent acute myocardial infarction and 1.6% developed MACE (n=2; both coronary stenoses without revascularisation). 9.9% of patients were classified as ‘high-risk’, 95.7% of whom developed MACE. Conclusions The Manchester Acute Coronary Syndromes (MACS) rule has the potential to safely reduce unnecessary hospital admissions and facilitate judicious use of high dependency resources.

Objective  To ascertain long term cardiovascular outcomes in patients whose chest pain remained undiagnosed six months after first presentation. Design  Cohort study. Setting  UK electronic health record database (CALIBER) linking primary care, secondary care, coronary registry, and death registry information. Participants  172 180 adults aged ≥18 from 223 general practices presenting with a first episode of recorded chest pain, classified from medical records as diagnosed (non-coronary condition or angina) or undiagnosed (cause unattributed) at first consultation between 2002 and 2009 and with no previous record of cardiovascular disease. Main outcome measures  Fatal or non-fatal cardiovascular events over 5.5 years' follow-up. Adjustments were made for age, sex, deprivation, body mass index, smoking status, year of index presentation, and previous records of diabetes or hypertension or previous prescriptions for lipid lowering drugs. Results  At the index presentation, 72.4% of patients (124 688) did not have a cause attributed for their chest pain; 118 687 (95.2%) of these did not receive any type of cardiovascular diagnosis over the next six months. Only a minority of patients in all three groups (non-coronary 2.0% (769 of 39 232); unattributed 11.7% (14 582 of 124 688); angina 31.5% (2606 of 8260)) had a recorded cardiac diagnostic investigation in the first six months after presentation. The long term incidence of cardiovascular events was higher in those whose chest pain remained unattributed after six months (5126 of 109 628; 4.7%) compared with patients with an initial diagnosis of non-coronary pain (1073 of 36 097; 3.0%) (adjusted hazard ratios for 0.5-1 year after presentation: 1.95, 95% confidence interval 1.66 to 2.31; for 1-3 years: 1.35, 1.23 to 1.48); for 3-5.5 years: 1.21, 1.08 to 1.37). Owing to the larger number of patients in the unattributed group, there were more excess myocardial infarctions in the long term in this group (214 more than expected based on the rate in the non-coronary group) than in the angina group (132 more than expected). Patients who had cardiac diagnostic investigations in the first six months had a higher long term risk of cardiovascular events, regardless of the initial chest pain label. Incidence of unattributed chest pain and angina decreased between 2002 (124 per 10 000 person years and 13 per 10 000 person years, respectively) and 2009 (107 per 10 000 person years and 5 per 10 000 person years, respectively), but the incidence of chest pain attributed to a non-coronary cause remained stable (37-40 per 10 000 person years). Risk of cardiovascular events did not change over time. Conclusions  Most patients with first onset chest pain do not have a diagnosis recorded at presentation or in the subsequent six months, including those who undergo cardiac investigations. These patients have an increased risk of cardiovascular events for at least five years. Efforts to better assess and reduce the cardiovascular risk of such patients are warranted.

Male, 69 FINAL DIAGNOSIS: Coronary artery to pulmonary artery fistula Symptoms: Chest pain Medication: - Clinical Procedure: Echocardiography • angiography • surgical intervention Specialty: Cardiology • Cardiac Surgery. Rare disease. A coronary artery fistula is an abnormal communication between a coronary artery and one of the cardiac chambers or a great vessel, so bypassing the myocardial capillary network. They are usually discovered incidentally upon coronary angiography. Clinical manifestations are variable depending on the type of fistula, the severity of shunt, site of shunt, and presence of other cardiac condition. We report a 69-year-old man without any previous medical history, who was admitted to our hospital with chest pain. The electrocardiogram (ECG) showed a sinus rhythm with ST depression in V2 to V6 precordial leads. Coronary angiography revealed a coronary artery fistula from left anterior descending coronary artery (LAD) to the main pulmonary artery, right coronary artery blockage and significant stenoses on the LAD and left circumflex artery (LCX). Surgical treatment was chosen because of the total occlusion of the right coronary artery and to relieve of pain to improve quality of life.

Prognostic significance of normal quantitative planar thallium-201 stress scintigraphy in patients with chest pain

Wackers, F.J.; Russo, D.J.; Russo, D.

The prognostic significance of normal quantitative planar thallium-201 stress scintigraphy was evaluated in patients with a chest pain syndrome. The prevalence of cardiac events during follow-up was related to the pretest (that is, before stress scintigraphy) likelihood of coronary artery disease determined on the basis of symptoms, age, sex and stress electrocardiography. In a consecutive series of 344 patients who had adequate thallium-201 stress scintigrams, 95 had unequivocally normal studies by quantitative analysis. The pretest likelihood of coronary artery disease in the 95 patients had a bimodal distribution. During a mean follow-up period of 22 +/- 3 months, no patientmore » died. Three patients (3%) had a cardiac event: two of these patients (pretest likelihood of coronary artery disease 54 and 94%) had a nonfatal myocardial infarction 8 and 22 months, respectively, after stress scintigraphy, and one patient (pretest likelihood 98%) underwent percutaneous transluminal coronary angioplasty 16 months after stress scintigraphy for persisting anginal complaints. Three patients were lost to follow-up; all three had a low pretest likelihood of coronary artery disease. It is concluded that patients with chest pain and normal findings on quantitative thallium-201 scintigraphy have an excellent prognosis. Cardiac events are rare (infarction rate 1% per year) and occur in patients with a moderate to high pretest likelihood of coronary artery disease.« less

We report two cases of acute cervical angina and ECG changes induced by anteflexion of the head. Cervical angina is defined as chest pain that resembles true cardiac angina but originates from cervical discopathy with nerve root compression. In these patients, Prinzmetal's angina, valvular heart disease, congenital heart disease, left ventricular aneurysm, and cardiomyopathy were excluded. After all, the patient's chest pain was reproduced by anteflexion of head, at this time, their ECGs showed nonspecific ST-T changes in the inferior and anterior leads different from the basal ECG. ECG changes returned to normal when the patient's neck moved to the neutral position. To our knowledge, these are the first cases of cervical angina associated with acute ECG changes by neck motion.

Post-surgical chest tube removal (CTR) is associated with a significant pain and discomfort for patients. Current treatment strategies for reducing CTR-associated pain and anxiety are limited and partially efficacious. To determine the effects of cold application, inhalation of lavender essential oil, and their combination on pain and anxiety during CTR was investigated. This randomized controlled open-label trial was conducted with 80 patients in the cardiac surgery intensive care unit who had a chest tube for duration of at least 24 hours after coronary artery bypass grafting (CABG). Patients were randomized (n=20 in each group) to receive cold application, aromatherapy with lavender oil, cold application in combination with lavender oil inhalation, or none of the above interventions (control group). The intensity and quality of pain and anxiety were evaluated using the visual analogue scale, short form and modified-McGill pain questionnaire (SFM-MPQ) and the Spielberger situational anxiety level inventory (STAII) scale, respectively. Patients in all treatment groups had significantly lower pain intensity and anxiety compared with the control group immediately, 5, 10 and 15 min after CTR. There was no statistically significant difference in the SFM-MPQ total scores between the intervention groups. With respect to anxiety score, there was a significantly reduced anxiety level immediately after CTR in the aromatherapy and cold-aromatherapy combination groups versus the cold application group. The present results suggested the efficacy of cold application and aromatherapy with lavender oil in reducing pain and anxiety associated with post-CABG CTR. PMID:27047319

Conventional emergency department (EMD) approach to triaging acute chest pain syndromes may lead to unnecessary admissions, resulting to in-hospital bed occupancy and increased healthcare costs. We explore the diagnostic utility of early (less than a week) outpatient scheduled single photon emission computed tomography (SPECT) in intermediate-risk chest pain subjects who presented to EMD with non-diagnostic electrocardiogram and negative serum troponin level. Additionally, we intend to study the safety and cost-effectiveness of such a strategy. We conduct a prospective, non-randomized study of 108 subjects who fit the inclusion criteria. After SPECT studies, all subjects were evaluated in the cardiac clinic within 2 weeks of EMD visits. Final diagnosis of coronary artery disease and subsequent disposition to standard medical therapy or follow-on angiography were decided by incorporating pre-test clinical data and SPECT results. Adverse events defined as myocardial infarction and cardiac death was tracked between EMD visit and eventual therapy (either medical therapy or coronary revascularization). Finally, cost-effectiveness was determined based on estimated cost and days of hospitalization saved between standard strategies of ward admission for further evaluation versus the present early outpatient SPECT-based workflow. Among 108 subjects (mean age 58 years, 59% male) included for analysis, 82 (76%) had normal perfusion status. There was no statistical difference in baseline characteristics and prior ischemic heart disease history between groups. In the 26 abnormal perfusion subjects, seven had follow-on coronary angiography in which three were found to have significant stenotic coronary lesions, but only one had intervention performed. There was an unscheduled coronary angiography in the normal perfusion group that yielded normal coronary anatomy. There was no adverse clinical event in both groups. Compared with standard strategy, early outpatient SPECT initiated by EMD physicians followed by cardiac clinic evaluation resulted in 2.9 days of hospitalization or $781.23 saved per patient per EMD visit. EMD-initiated early SPECT studies followed by cardiac clinic evaluation in intermediate-risk acute chest pain syndromes with non-diagnostic ECG and negative serum troponin levels carries excellent diagnostic and therapeutic utility, in addition to being safe and cost-effective.

Pragmatic approach to chest pain patients discharged with undetectable high-sensitivity troponin T and normal electrocardiogram: the STABS + CT protocol.

Bishop, Warrick; Girao, Gary

2017-06-01

A strategy that discharges chest pain patients with negative high-sensitivity troponin and non-ischaemic electrocardiography changes may still result in 0.44% of patients experiencing myocardial infarction within 30 days. We observed that a pragmatic approach that systematically discharged 25 patients on cardio-protective medications of aspirin, metoprolol and atorvastatin followed with prompt (<10 days) coronary computed tomography angiography resulted in no major adverse cardiac event and adverse drug reaction 30 days post-presentation. The strategy resulted in three patients (12%) ultimately diagnosed with likely unstable angina, which required planned coronary intervention in two patients and medical management in one patient. No unplanned readmissions for chest pains were noted from initial presentation through to 6-month follow up. © 2017 Royal Australasian College of Physicians.

Mesalamine is a common treatment for Crohn's disease, and can be rarely associated with myocarditis through a mechanism of drug hypersensitivity. We present the case of a 19-year-old male who developed chest pain two weeks after beginning mesalamine therapy. The electrocardiogram showed slight ST-segment elevation with upward concavity in the inferolateral leads; blood tests demonstrated elevated troponin I and the echocardiogram revealed moderately depressed left ventricular systolic function with global hypocontractility. Cardiac magnetic resonance imaging confirmed the diagnosis of myocarditis, revealing multiple areas of subepicardial fibrosis. The onset of symptoms after mesalamine, and improvement of chest pain, cardiac biomarkers and left ventricular systolic function after discontinuing the drug, suggest that our patient suffered from a rare drug-hypersensitivity reaction to mesalamine.

Non-invasive assessment of low- and intermediate-risk patients with chest pain

2016-01-01

Coronary artery disease (CAD) remains a significant global public health burden despite advancements in prevention and therapeutic strategies. Common non-invasive imaging modalities, anatomic and functional, are available for the assessment of patients with stable chest pain. Exercise electrocardiography is a long-standing method for evaluation for CAD and remains the initial test for the majority of patients who can exercise adequately with a baseline interpretable electrocardiogram. The addition of cardiac imaging to exercise testing provides incremental benefit for accurate diagnosis for CAD and is particularly useful in patients who are unable to exercise adequately and/or have uninterpretable electrocardiograms. Radionuclide myocardial perfusion imaging and echocardiography with exercise or pharmacological stress provide high sensitivity and specificity in the detection and further risk stratification of patients with CAD. Recently, coronary computed tomography angiography has demonstrated its growing role to rule out significant CAD given its high negative predictive value. Although less available, stress cardiac magnetic resonance provides a comprehensive assessment of cardiac structure and function and provides a high diagnostic accuracy in the detection of CAD. The utilization of non-invasive testing is complex due to various advantages and limitations, particularly in the assessment of low- and intermediate-risk patients with chest pain, where no single study is suitable for all patients. This review will describe currently available non-invasive modalities, along with current evidence-based guidelines and appropriate use criteria in the assessment of low- and intermediate-risk patients with suspected, stable CAD.

The HEART score is a simple scoring system, ranging from 0 to 10, specifically developed for risk stratification of patients with undifferentiated chest pain. It has been validated for the conventional troponin, but not for high-sensitive troponin. We assess a modified version of the HEART score using a single high-sensitivity troponin T dosage at presentation, regardless of symptom duration, and with different ECG criteria to evaluate if the patients with a low HEART score could be safely discharged early. The secondary aim was to confirm a statistically significant difference in each HEART score group (low 0-3, intermediate 4-6, high 7-10) in the occurrence of major adverse cardiac events at 30 and 180 days. We retrospectively analyzed the HEART score of 1597 consecutive patients admitted to the Emergency Department of our Hospital for chest pain between January 1 and June 30, 2014. Of these, 190 did not meet the inclusion criteria and 29 were lost to follow-up. None of the 512 (37.2 %) patients with a low HEART score had an event within 180 days. The difference between the cumulative incidences of events in the three HEART score groups was statistically significant (P < 0.0001). We demonstrate that it might be possible to safely discharge Emergency Department chest pain patients with a low modified HEART score after an initial determination of high-sensitive troponin T, without a prolonged observation period or an additional cardiac testing.

A 42-year-old man was admitted to coronary care for assessment with severe retrosternal chest pain. Echocardiography showed significant external compression of the left atrium. A subsequent CT scan revealed him to have a large hiatus hernia, with most of his stomach herniating into his thorax causing left atrial compression and gastric volvulus. He subsequently underwent successful emergency decompression of the gastric volvulus and repair of his hiatus hernia. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Aim To evaluate the diagnostic quality of a new multiple detector-row computed tomography angiography (MDCT-A) protocol using low dose radiation and low volume contrast medium techniques for evaluation of non-cardiac chest pain. Methods Forty-five consecutive patients with clinically suspected noncardiac chest pain and requiring contrast-enhanced chest computed tomography (CT) were examined. The patients were assigned to the protocol, with 80 kilovolt (peak) (kV[p]) and 150 effective milliampere-second (eff mA-s). In our study group, 40 mL of low osmolar contrast material was administered at 3.0 mL/s. Results In the study group, four patients with pulmonary embolism, four with pleural effusion, two with ascending aortic aneurysm and eight patients with pneumonic consolidation were detected. The mean attenuation of the pulmonary truncus and ascendant aortic locations was considered 264±44 and 249±51 HU, respectively. The mean effective radiation dose was 0.83 mSv for MDCT-A. Conclusions Pulmonary artery and the aorta scanning simultaneously was significantly reduced radiation exposure with the mentioned dose saving technique. Additionally, injection of low volume (40 cc) contrast material may reduce the risk of contrast induced nephropathy, therefore, facilitate the diagnostic approach. This technique can be applied to all cases and particularly patients at high risk of contrast induced nephropathy due to its similar diagnostic quality with a low dose and high levels of arteriovenous enhancement simultaneously.

In cardiac magnetic resonance imaging, hyperenhancement of the pericardium post gadolinium administration in acute chest pain often signifies pericarditis with an acute inflammatory response and neovascularization. In the context of constrictive pericarditis, case series have indicated that the intensity of hyperenhancement and the thickness of the pericardium imply reversibility of the physiology of the constrictive pericarditis. We present a case of intense hyperenhancement and marked thickening of the pericardium in a patient with constrictive pericarditis with antecedent chest pain. Surgical resection of the pericardium and microscopy revealed a chronic fibrotic state with no evidence of inflammation or neovascularization, thus clarifying the failure of initial medical/anti-inflammatory treatment. Our case highlights the fact that hyperenhancement of the pericardium post gadolinium is non-specific for histology and does not necessarily imply the reversibility of pericardial constriction. © 2016 S.

Evaluation of acute chest pain is highly variable. To evaluate the cost-effectiveness of strategies using cardiac markers and noninvasive tests for myocardial ischemia. Cost-effectiveness analysis. Prospective data from 1066 patients with chest pain and from the published literature. Patients admitted with acute chest pain. Lifetime. Societal. Creatine kinase (CK)-MB mass assay alone; CK-MB mass assay followed by cardiac troponin I assay if the CK-MB value is normal; CK-MB mass assay followed by troponin I assay if the CK-MB value is normal and electrocardiography shows ischemic changes; both CK-MB mass and troponin I assays; and troponin I assay alone. These strategies were evaluated alone or in combination with early exercise testing. Lifetime cost, life expectancy (in years), and incremental cost-effectiveness. For patients 55 to 64 years of age, measurement of CK-MB mass followed by exercise testing in appropriate patients was the most competitive strategy ($43000 per year of life saved). Measurement of CK-MB mass followed by troponin I measurement had an incremental cost-effectiveness ratio of $47400 per year of life saved for patients 65 to 74 years of age; it was also the most cost-effective strategy when early exercise testing could not be performed, CK-MB values were normal, and ischemic changes were seen on electrocardiography. Results were influenced by age, probability of myocardial infarction, and medical costs. Measurement of CK-MB mass plus early exercise testing is a cost-effective initial strategy for younger patients and those with a low to moderate probability of myocardial infarction. Troponin I measurement can be a cost-effective second test in higher-risk subsets of patients if the CK-MB level is normal and early exercise testing is not an option.

Limited information exists regarding the significance of dyspnea in patients who are unable to exercise and the contribution of myocardial ischemia to this symptom. To assess this, we evaluated results of dobutamine stress echocardiography (DSE) and long-term outcome of patients with dyspnea referred for DSE. We studied 6,376 consecutive patients who were unable to perform an exercise test and were referred for DSE. Patients were classified according to presenting symptoms and followed for 5.5 +/- 2.8 years. End points were cardiac ischemic events (myocardial infarction or revascularization), hospitalization for heart failure (HF), and death. Dobutamine stress echocardiogram was positive for ischemia in 19% of patients with dyspnea versus 24% (p = 0.002) of those with typical angina and 17% (p = 0.2) of asymptomatic patients. In multivariate analysis, risk of death was increased in dyspneic patients versus asymptomatic patients (hazard ratio [HR] 1.14, p = 0.02) and patients with chest pain (HR 1.20, p <0.001). Hospitalization for HF occurred more often in patients with dyspnea (HR 1.26, p = 0.05 vs asymptomatic; HR 1.24, p = 0.06 vs chest pain), especially in the subset without previous HF (HR 1.45, p = 0.006 vs chest pain). Risk of cardiac ischemic events in patients with dyspnea was similar versus asymptomatic patients (HR 0.92, p = 0.39) and decreased versus patients with chest pain (HR 0.70, p <0.001). In conclusion, in patients referred for DSE, dyspnea was associated with a poor outcome. This increased hazard seems not to be linked to myocardial ischemia, but instead to HF and death.

The influence of non-medical factors on physicians' decision-making has been documented in many observational studies, but rarely in an experimental setting capable of demonstrating cause and effect. We conducted a controlled factorial experiment to assess the influence of non-medical factors on the diagnostic and treatment decisions made by practitioners of internal medicine in two common medical situations. One hundred and ninety-two white male internists individually viewed professionally produced video scenarios in which the actor-patient, presenting with either chest pain or dyspnea, possessed various balanced combinations of sex, race, age, socioeconomic status, and health insurance coverage. Physician subjects were randomly drawn from lists of internists in private practice, hospital-based practice, and HMO's, at two levels of experience. The most frequent diagnoses for both chest pain and dyspnea were psychogenic origin and cardiac problems. Smoking cessation was the most frequent treatment recommendation for both conditions. Younger patients (all other factors being the same) were significantly more likely to receive the psychogenic diagnosis. Older patients were more likely to receive the cardiac diagnosis for chest pain, particularly if they were insured. HMO-based physicians were more likely to recommend a follow-up visit for chest pain. Several interactions of patient and physician factors were significant in addition to the main effects. The variability in decision-making evidenced by physicians in this experiment was not entirely accounted for by strictly rational Bayesian inference (the common prescriptive model for medical decision-making), in-as-much as non-medical factors significantly affected the decisions that they made. There is a need to supplement idealized medical schemata with considerations of social behavior in any comprehensive theory of medical decision-making.

The present study was to investigate whether the HEART score can be used to evaluate cardiovascular risks and reduce unnecessary cardiac imaging in China.Acute coronary syndrome patients with the thrombosis in myocardial infarction risk score < 2 were enrolled in the emergency department. Baseline data were collected and a HEART score was determined in each participant during the indexed emergency visit. Participants were follow-up for 30 days after discharge and the studied endpoints included acute myocardial infarction, cardiovascular mortality and all-cause mortality.A total of 244 patients were enrolled and 2 was loss of follow-up. The mean age was 50.4 years old and male patients accounted for 64.5%. Substernal pain and featured as pressure of the pain accounted for 34.3% and 39.3%, respectively. After 30 days' follow-up, no patient in the low-risk HEART score group and 2 patients (1.5%) in the high risk HEART score group had cardiovascular events. The sensitivity of HEART score to predict cardiovascular events was 100% and the specificity was 46.7%. The potential unnecessary cardiac testing was 46.3%. Cox proportional hazards regression analysis showed that per one category increase of the HEART score was associated with nearly 1.3-fold risk of cardiovascular events.In the low-risk acute chest pain patients, the HEART score is useful to physicians in evaluating the risk of cardiovascular events within the first 30 days. In addition, the HEART score is also useful in reducing the unnecessary cardiac imaging.

Animal studies suggest that monocyte chemoattractant protein-1 (MCP-1) is a promising biomarker for coronary artery atherosclerosis (CAA), but human studies have been inconclusive. To determine potential relationships between plasma MCP-1 and CAA in patients with acute chest pain. A secondary analysis of 150 patients enrolled in emergency department chest pain risk stratification clinical investigations was conducted. Participants with stored blood and known coronary phenotypes (determined by coronary angiography) were selected using stratified randomization such that 50 patients were included into 3 groups: (1) no angiographic evidence of CAA, (2) nonobstructive CAA, and (3) obstructive CAA (stenosis ≥ 70%). Plasma MCP-1 levels were determined by enzyme-linked immunosorbent assay. The association between MCP-1 and obstructive CAA or any CAA was modeled using logistic regression. Variables in the unreduced model included age, sex, race, prior diagnosis of CAA or acute coronary syndrome, hyperlipidemia, hypertension, diabetes, smoking, and cardiac troponin I measurement. Among the 150 participants, 65.3% (98/150) had invasive coronary angiography and 34.7% (52/150) had coronary computed tomographic angiography. Myocardial infarction occurred in 27.3% (41/150) and coronary revascularization occurred in 26% (39/150) of the participants. Each 10 pg/mL increase in MCP-1 measurement was associated with an odds ratio of 1.12 (95% confidence interval, 1.06-1.19) for obstructive CAA. MCP-1 remained a significant predictor of obstructive CAA and any CAA after adjustment for age, sex, race, traditional cardiac risk factors, and cardiac troponin I. MCP-1 is independently associated with CAA among emergency department patients with chest pain.

Hydatid cyst is a tissue parasitic infection caused by tapeworm Echinococcus granulosus. Common location for hydatid cysts are the liver (65%) and the lungs (25%). Cardiac hydatid cyst is seen rarely, occurring in about 0.5-2% of all cases of hydatid disease. We present this case of 45 years female who presented with short duration of dry cough and atypical chest pain. Chest X ray showed cardiomegaly with round bulge at the right heart border and curvilinear calcification in left upper abdomen in the region of spleen. Transthoracic echocardiography (TTE) depicted cystic lesion in Right Ventricle free wall causing compression of right atrial and ventricular cavity. Cardiac CT confirmed this cyst as hydatid cyst. Patient underwent successful excision of right ventricular hydatid cyst. © Journal of the Association of Physicians of India 2011.

Chest tubes are used in every case of coronary artery bypass grafting (CABG) to evacuate shed blood from around the heart and lungs. This study was designed to assess the effective of Jackson-Pratt drain in compare with conventional chest drains after CABG. This was a randomized controlled trial that conducted on 218 patients in Chamran hospital from February to December 2016. Eligible patients were randomized in a 1:1 ratio. Jackson-Pratt drain group had 109 patients who received a chest tube insertion in the pleural space of the left lung and a Jackson-Pratt drain in mediastinum, and Chest tube drainage group had 109 patients who received double chest tube insertion in the pleural space of the left lung and the mediastinum. The incidence of pleural effusions in Jackson-Pratt drain group and chest tube group were not statistically different. The pain score at 2-h in Drain group was significantly higher than chest tube group ( P = 0.001), but the trend of pain score between groups was not significantly different ( P = 0.097). The frequency of tamponade and atrial fibrillation (AF) were significantly lower in Jackson-Pratt drain group ( P < 0.05). The Jackson-Pratt drain is equally effective for preventing cardiac tamponade, pleural effusions, and pain intensity in patients after CABG when compared with conventional chest tubes, but was significantly superior regarding efficacy to hospital and Intensive Care Unit length of stay and the incidence of AF.

Low-risk patients with chest pain are often admitted to monitored beds; however, the use of telemetry beds in this cohort is not evidence based. We tested the hypothesis that monitoring admitted low-risk patients with chest pain for dysrhythmia is low yield (<1% detection of life-threatening dysrhythmias requiring treatment). We conducted a prospective cohort study of emergency department (ED) patients with chest pain with a Goldman risk score of less than 8%, a normal initial creatine kinase-MB level, and a negative initial troponin I level admitted to non-ICU monitored beds. Investigators followed the hospital course daily. The main outcome was cardiovascular death and life-threatening ventricular dysrhythmia during telemetry. Of 3,681 patients with chest pain who presented to the ED, 1,750 patients were admitted to non-ICU monitored beds. Of these, 1,029 patients had a Goldman risk score of less than 8%, a troponin I level of less than 0.3 ng/mL, and a creatine kinase-MB level of less than 5 ng/mL (accounting for 59% of all chest pain telemetry admissions). During hospitalization, there were no patients with sustained ventricular tachycardia/ventricular fibrillation requiring treatment on the telemetry service (0%; 95% confidence interval [CI] 0% to 0.3%). There were 2 deaths: neither was cardiovascular in nature or preventable by monitoring (cardiovascular preventable death rate=0%; 95% CI 0.0% to 0.3%). The routine use of telemetry monitoring for low-risk patients with chest pain is of limited utility. Admission to nonmonitored beds might help alleviate ED crowding without increasing risk of adverse events caused by dysrhythmia in patients with a Goldman risk of less than 8%, an initial troponin I level of less than 0.3 ng/mL, and a creatine kinase-MB level of less than 5 ng/mL.

Research suggests that female patients with acute coronary syndrome (ACS) experience delays in emergency department (ED) management and are less likely to receive guideline-based treatments and referrals for follow-up testing. Women are often found to have poorer clinical outcomes in comparison to men. This study aimed to assess current sex differences in the presentation, management and outcomes of patients with undifferentiated chest pain presenting to a tertiary ED. Data were analysed from two prospective studies conducted at a single Australian site between 2007 and 2014. Eligible patients were those of 18 years of age or older presenting with at least 5 minutes of chest pain or other symptoms for which the treating physician planned to investigate for possible ACS. Presenting symptoms, ED time measures, follow-up testing and outcomes, including 30-day ACS and mortality, were measured and compared between male and female patients. Of 2349 (60% men) patients presenting with chest pain, 153 men and 51 women were diagnosed with ACS within 30days . Presenting symptoms were similar in men and women with confirmed ACS. Time from symptom onset to ED presentation, time spent in the ED and total time in hospital were similar between the sexes. Male and female patients had similar rates of follow-up provocative testing. After adjustment for clinical factors, the odds of undergoing angiography were 1.8 (95% CI: 1.36-2.40) times higher for men than women. Of those undergoing coronary angiography within 30 days, a smaller proportion of women, compared to men, received revascularisation. Within 30 days, three (0.2%) male and one (0.1%) female patient died. Minimal sex differences were observed in the contemporary emergency management of patients presenting with suspected ACS. Thirty-day outcomes were similarly low in men and women despite lower rates of coronary angiography and revascularisation in women. Further research is required to replicate these results in different hospital systems and cultural settings.

Rural patients can wait up to 32 hours for transfer to cardiac catheterization (CATH) for events related to acute coronary syndrome (ACS). Pain arising from myocardial ischemia can be severe and anxiety-provoking. Pain management during this time should be optimized in order to preserve vulnerable myocardial muscle. This qualitative focus group study solicited the perspectives of ACS patients and emergency staff nurses on the rural patient experience of cardiac pain and anxiety and priorities and barriers to optimal assessment and management of ACS pain. Patients described ACS pain as moderate to severe, with pain in the chest, arms, back, shoulders, and jaw. Pain was well assessed and managed upon arrival in the emergency department but anxiety was not routinely assessed or treated. Barriers identified were poor management of patients with different acuity levels, high patient volumes, and assumptions regarding patients' communication about pain. Research related to ACS pain and anxiety management in the rural context is recommended. Copyright© by Ingram School of Nursing, McGill University.

The Alfred Emergency Short Stay Unit initiated a chest pain protocol for patients presenting with chest pain to risk stratify for acute coronary syndrome (ACS). A 30-day follow-up of patients discharged with low-or-intermediate risk of ACS demonstrated no deaths or ACS. The purpose of this study was to evaluate the long-term safety of the chest pain protocol, a one year follow-up was undertaken. A questionnaire was designed for the one-year follow-up and it was administered via a telephone interview by emergency nurses to document adverse cardiac events and health care utilisation. From 297 patients, 224 (75%) were contacted 12 months following discharge. There was one death from stroke (0.4%; 95% confidence interval (CI): 0.01-2.5%) and another from an unknown cause. Five patients had been diagnosed with atrial fibrillation (2.2%; 95% CI: 0.7-5.1%), two patients had an acute myocardial infarction (0.9%; 95% CI: 0.03-2.1%) and four were diagnosed with angina (1.8%; 95% CI: 0.9-3.2%). Nearly half (n=103, 46%; 95% CI: 39.5-52.5%) had returned to the emergency department (ED) for various conditions including 42 patients with further chest pain. Ninety-six patients (43%; 95% CI: 39.3-52.7%) had specialist referrals and 124 investigations were performed. Thirty-four patients had cardiology referrals (15%; 95% CI: 10.7-20.5%) and 25 patients had gastroenterology referrals (11%; 95% CI: 7.3-16.0%). Diagnostic cardiac tests were performed on 38 patients: coronary angiography (n=10), 24-hour Holter monitoring (n=17), 24-hour blood pressure (BP) monitoring (n=4), thallium scans (n=5), exercise stress test (n=1) and CT scan (n=1). Patients had a low risk of adverse events 12 months after discharge but substantial continuing health care utilization was observed. Complete assessment by health care professionals prior to discharge may help mitigate representations. © The European Society of Cardiology 2014.

First Update of the Criteria for Certification of Chest Pain Units in Germany: Facelift or New Model?

2016-03-01

In an effort to provide a systematic and specific standard-of-care for patients with acute chest pain, the German Cardiac Society introduced criteria for certification of specialized chest pain units (CPUs) in 2008, which have been replaced by a recent update published in 2015. We reviewed the development of CPU establishment in Germany during the past 7 years and compared and commented the current update of the certification criteria. As of October 2015, 228 CPUs in Germany have been successfully certified by the German Cardiac Society; 300 CPUs are needed for full coverage closing gaps in rural regions. Current changes of the criteria mainly affect guideline-adherent adaptions of diagnostic work-ups, therapeutic strategies, risk stratification, in-hospital timing and education, and quality measures, whereas the overall structure remained unchanged. Benchmarking by participation within the German CPU registry is encouraged. Even though the history is short, the concept of certified CPUs in Germany is accepted and successful underlined by its recent implementation in national and international guidelines. First registry data demonstrated a high standard of quality-of-care. The current update provides rational adaptions to new guidelines and developments without raising the level for successful certifications. A periodic release of fast-track updates with shorter time frames and an increase of minimum requirements should be considered.

Within internal medicine, cardiac and neurologic pathology comprises a vast majority of patient complaints. Physicians and advanced-care practitioners must be highly educated and comfortable in the evaluation, diagnosis, and management of these entities. Chest pain accounts for millions of annual visits to the emergency room with pericarditis diagnosed in approximately four percent of patients with nonischemic chest pain. Guillain-Barre Syndrome is autoimmune polyneuropathy that often results in transient paralysis. Simultaneous diagnosis of both entities is a rare but described phenomenon. Here, we present a clinical case of GBS associated pericarditis. A fifty-five-year-old man with history of renal transplant presented with lower extremity weakness and urinary incontinence. Physical exam and diagnostic studies confirmed Guillain-Barre Syndrome. Patient subsequently developed stabbing chest pain with clinical presentation and electrocardiogram consistent with pericarditis. The patient was successfully treated for both diseases. This case highlights that although infrequent, internal medicine care providers must be cognizant of this correlation to ensure timely diagnosis and treatment. PMID:26664359

Background: Chest tubes are used in every case of coronary artery bypass grafting (CABG) to evacuate shed blood from around the heart and lungs. This study was designed to assess the effective of Jackson-Pratt drain in compare with conventional chest drains after CABG. Materials and Methods: This was a randomized controlled trial that conducted on 218 patients in Chamran hospital from February to December 2016. Eligible patients were randomized in a 1:1 ratio. Jackson-Pratt drain group had 109 patients who received a chest tube insertion in the pleural space of the left lung and a Jackson-Pratt drain in mediastinum, and Chest tube drainage group had 109 patients who received double chest tube insertion in the pleural space of the left lung and the mediastinum. Results: The incidence of pleural effusions in Jackson-Pratt drain group and chest tube group were not statistically different. The pain score at 2-h in Drain group was significantly higher than chest tube group (P = 0.001), but the trend of pain score between groups was not significantly different (P = 0.097). The frequency of tamponade and atrial fibrillation (AF) were significantly lower in Jackson-Pratt drain group (P < 0.05). Conclusion: The Jackson-Pratt drain is equally effective for preventing cardiac tamponade, pleural effusions, and pain intensity in patients after CABG when compared with conventional chest tubes, but was significantly superior regarding efficacy to hospital and Intensive Care Unit length of stay and the incidence of AF.

In the past, ambulatory 24-h manometry has been shown useful for the evaluation of patients with non-cardiac chest pain (NCCP). With the diagnostic improvements brought by pH-impedance monitoring and high-resolution manometry (HRM), the contribution of ambulatory 24-h manometry to the diagnosis of esophageal hypertensive disorders has become uncertain. Our aim was to assess the additional diagnostic yield of ambulatory manometry to HRM and ambulatory pH-impedance monitoring in this patient population. All patients underwent 24-h ambulatory pressure-pH-impedance monitoring and HRM. Patients had retrosternal pain as a predominant symptom and no explanation after cardiologic and digestive endoscopic evaluations. Diagnostic measurements were analyzed by two independent physicians. Fifty-nine patients met the inclusion criteria; 37.3% of the patients had their symptoms explained by abnormalities on pH-impedance monitoring and 6.8% by ambulatory manometry. Functional chest pain was diagnosed in 52.5% of the patients. High-resolution manometry, using the Chicago Classification v3.0 criteria alone, did not identify any of the four patients with esophageal spasm on ambulatory manometry. However, taking into account other abnormalities, such as simultaneous (rapid) or repetitive contractions, HRM had a sensitivity of 75% and a specificity of 98.2% for the diagnosis of esophageal spasm. In the work-up of NCCP, ambulatory 24-h manometry has a low additional diagnostic yield. However, it remains the best technique to identify esophageal spasm as the cause of symptoms. This is particularly useful when an unequivocal diagnosis is needed before treatment. © 2016 John Wiley & Sons Ltd.

In patients consulting in the Emergency Department for chest pain, a HEART score ≤ 3 has been shown to rule out an acute coronary syndrome (ACS) with a low risk of major adverse cardiac event (MACE) occurrence. A negative CARE rule (≤ 1) that stands for the first four elements of the HEART score may have similar rule-out reliability without troponin assay requirement. We aim to prospectively assess the performance of the CARE rule and of the HEART score to predict MACE in a chest pain population. Prospective two-center non-interventional study. Patients admitted to the ED for non-traumatic chest pain were included, and followed-up at 6 weeks. The main study endpoint was the 6-week rate of MACE (myocardial infarction, coronary angioplasty, coronary bypass, and sudden unexplained death). 641 patients were included, of whom 9.5% presented a MACE at 6 weeks. The CARE rule was negative for 31.2% of patients, and none presented a MACE during follow-up [0, 95% confidence interval: (0.0-1.9)]. The HEART score was ≤ 3 for 63.0% of patients, and none presented a MACE during follow-up [0% (0.0-0.9)]. With an incidence below 2% in the negative group, the CARE rule seemed able to safely rule out a MACE without any biological test for one-third of patients with chest pain and the HEART score for another third with a single troponin assay.

Pain is a serious health care problem and there is growing evidence to support the use of hypnosis and cognitive-behavioral interventions for pain management. This article reviews clinical techniques and methods of cognitive hypnotherapy for pain management. Current research with emphasis given to randomized, controlled trials is presented and the efficacy of hypnotherapy for pain management is discussed. Evidence for cognitive hypnotherapy in the treatment in chronic pain, cancer, osteoarthritis, sickle cell disease, temporomandibular disorder, fibromyalgia, non-cardiac chest pain, and disability related chronic pains are identified. Implications for clinical practice and research are discussed in light of the accumulating evidence in support of the efficacy and effectiveness of cognitive hypnotherapy for pain management.

Despite improvements in identifying high-risk patients with non-ST segment ACS (acute coronary syndrome), low risk patients presenting with atypical chest pain and non-diagnostic Electrocardiogram (ECG) continued to undergo unnecessary admissions and testing. Since 1992, our chest pain protocol included using 4-hour serial biomarkers from ED admission in combination with stress testing to evaluate these patients. Our study aimed at determining whether a new accelerated diagnostic protocol using sensitive cardiac troponin I (cTnI) 2 hours after admission to the ED followed by stress testing is safe and effective in emergency settings, allowing for appropriate triage, earlier discharge and reducing costs. We conducted a single center randomized trial at Presence St. Francis Hospital Chest pain center in Evanston, Illinois enrolling sixty-four consecutive patients with atypical chest pain and non-diagnostic ECG, participants were randomized to accelerated 2 hrs protocol or our pre-existing 4-hrs protocol. Sixty patients completed the protocol and were randomized to either a 2-hour (29 patients) or 4-hour protocol using both I-STAT and PATHFAST cTnI (31 Patients). Troponin I was evaluated at 0 and at 2 hours from ED presentation with and additional draw for patients in the 4-hour rule out-group. Patients with normal serial biomarkers were then evaluated with stress testing and qualified for earlier discharge if the stress test was negative, while those with a positive biomarker at any time were admitted. Thirty-six patients had exercise treadmill stress test and 24 patients had either nuclear or Echo stress test. Fifty-three patients had a normal stress test and were discharged home. One patient in the 4-hour group with normal serial troponins developed ventricular tachycardia/fibrillation during the recovery period of a regular stress test. Six patients had a positive PATHFAST cTnI and a normal I-STAT cTnI at 2-hours. Two out of these six patients evaluated by coronary angiography. One patient had severe tortuous coronaries but no significant obstructive lesion and one had a severe CAD who needed Coronary artery bypass grafting (CABG). Three of the six patients had a normal stress test and one patient decided to leave without further testing. None of the patients with a normal stress test had a major cardiac event or adverse cardiac outcome at six-month follow up. This study demonstrates that the 2 hours accelerated protocol using high sensitivity Troponin assay at 0 and 2 hours with comprehensive clinical evaluation and ECG followed by stress testing might be successful in identifying low-risk patient population who may benefit from early discharge from ED reducing associated costs and length of stay.

Chest pain is one of the most common presentations to a hospital, and appropriate triaging of these patients can be challenging. The HEART score has been used for such purposes in some countries and only a few validation studies from the USA are available. We aim to determine the utility of the HEART score in patients presenting with chest pain to an inner-city hospital in the USA. We retrospectively screened 417 consecutive patients admitted with chest pain to the observation/telemetry units at Einstein Medical Center Philadelphia. After applying inclusion and exclusion criteria, 299 patients were included in the analysis. Patients were divided into low-risk (0-3) and intermediate-high (≥4)-risk HEART score groups. Baseline characteristics, thrombolysis in myocardial infarction score, need for revascularization during index hospitalization, and major adverse cardiovascular events (MACE) at 6 weeks and 12 months were recorded. There were 98 and 201 patients in the low-score group and intermediate-high-score group, respectively. Compared with the low-score group, patients in the intermediate-high-risk group had a higher incidence of revascularization during the index hospital stay (16.4 vs. 0%; P=0.001), longer hospital stay, higher MACE at 6 weeks (9.5 vs. 0%) and 12 months (20.4 vs. 3.1%), and higher cardiac readmissions. HEART score of at least 4 independently predicted MACE at 12 months (odds ratio 7.456, 95% confidence interval: 2.175-25.56; P=0.001) after adjusting for other risk factors in regression analysis. HEART score of at least 4 was predictive of worse outcomes in patients with chest pain in an inner-city USA hospital. If validated in multicenter prospective studies, the HEART score could potentially be useful in risk-stratifying patients presenting with chest pain in the USA and could impact clinical decision-making.

Low socioeconomic status is associated with increased mortality from coronary heart disease. We assessed total mortality, cardiac death, and sudden cardiac death (SCD) in relation to socioeconomic class and social security in 982 patients consecutively admitted with suspected coronary chest pain, living in the city of Salta, northern Argentina. Patients were divided into three socioeconomic classes based on monthly income, residential area, and insurance coverage. Five-year follow-up data were analyzed accordingly, applying univariate and multivariate analyses. At follow-up, 173 patients (17.6%) had died. In 92 patients (9.4%) death was defined as cardiac, of whom 59 patients (6.0%) were characterized as SCD. In the multivariate analysis, the hazard ratios (HRs) for all-cause and cardiac mortality in the highest as compared to the lowest socioeconomic class were 0.42 (95% confidence interval (CI), 0.22-0.80), P = 0.008, and 0.39 (95% CI, 0.15-0.99), P = 0.047, respectively. Comparing patients in the upper socioeconomic class to patients without healthcare coverage, HRs were 0.46 (95% CI, 0.23-0.94), P = 0.032, and 0.37 (95% CI, 0.14-1.01), P = 0.054, respectively. In conclusion, survival was mainly tied to socioeconomic inequalities in this population, and the impact of a social security program needs further attention.

Chest pain can be caused by various conditions, with life-threatening cardiac disease being of greatest concern. Prediction scores to rule out coronary artery disease have been developed for use in emergency settings. We developed and validated a simple prediction rule for use in primary care. We conducted a cross-sectional diagnostic study in 74 primary care practices in Germany. Primary care physicians recruited all consecutive patients who presented with chest pain (n = 1249) and recorded symptoms and findings for each patient (derivation cohort). An independent expert panel reviewed follow-up data obtained at six weeks and six months on symptoms, investigations, hospital admissions and medications to determine the presence or absence of coronary artery disease. Adjusted odds ratios of relevant variables were used to develop a prediction rule. We calculated measures of diagnostic accuracy for different cut-off values for the prediction scores using data derived from another prospective primary care study (validation cohort). The prediction rule contained five determinants (age/sex, known vascular disease, patient assumes pain is of cardiac origin, pain is worse during exercise, and pain is not reproducible by palpation), with the score ranging from 0 to 5 points. The area under the curve (receiver operating characteristic curve) was 0.87 (95% confidence interval [CI] 0.83-0.91) for the derivation cohort and 0.90 (95% CI 0.87-0.93) for the validation cohort. The best overall discrimination was with a cut-off value of 3 (positive result 3-5 points; negative result

A 38-year-old Caucasian man with a medical history significant for inflammatory bowel disease (IBD) and mesalamine use presented to the emergency department with stabbing, pleuritic, substernal chest pain over the previous 2 days. Findings of leucocytosis, elevated cardiac enzymes and inflammatory markers, T-wave or ST-segment abnormalities and left ventricular systolic dysfunction suggested mesalamine-induced myocarditis. However, a cardiac MRI confirmed the diagnosis. Signs and symptoms improved within days of withdrawal of mesalamine, and initiation of corticosteroids and follow-up studies within the next year were unremarkable. Importantly, the diagnosis of mesalamine-induced myocarditis confirmed via cardiac MRI is a step rarely performed in published cases. PMID:26341161

Patients presenting with chest pain and evidence of functional ischemia by myocardial perfusion imaging (MPI), but lacking commensurate angiographic disease pose a diagnostic and therapeutic dilemma. They are often dismissed as having 'false-positive MPI'. Moreover, a majority of the available long-term outcome data for it has been derived from homogenous female populations. In this study, we sought to evaluate the long-term outcomes of this presentation in a multiethnic male-predominant cohort. We retrospectively identified 47 patients who presented to our institution between 2002 and 2005 with chest pain and evidence of ischemia on MPI, but with no significant angiographic disease on subsequent cardiac catheterization (cases). The occurrence of adverse cardiovascular outcomes (chest pain, congestive heart failure, acute myocardial infarction and stroke) post-index coronary angiogram was tracked. Similar data was collected for 37 patients who also presented with chest pain, but normal MPI over the same period (controls). Overall average follow-up was over 22 months. Fifty-three percent (26/47) of the cases had one or more of the adverse outcomes as compared with 22% (8/37) of controls (P < 0.01). Of these, 13 (50.0%) and 3 (37.5%) were males, respectively. Ischemia on MPI is predictive of long-term adverse cardiovascular outcomes despite normal ('false-negative') coronary angiography. This appears to be gender-neutral.

Chest pain is often seen alongside with panic attacks. Moreover, panic disorder has been suggested as a risk factor for cardiovascular disease and even a trigger for acute coronary syndrome. Patients with coronary artery disease may have myocardial ischemia in response to mental stress, in which panic attack is a strong component, by an increase in coronary vasomotor tone or sympathetic hyperactivity setting off an increase in myocardial oxygen consumption. Indeed, coronary artery spasm was presumed to be present in cases of cardiac ischemia linked to panic disorder. These findings correlating panic disorder with coronary artery disease lead us to raise questions about the favorable prognosis of chest pain in panic attack. To investigate whether myocardial ischemia is the genesis of chest pain in panic attacks, we developed a myocardial perfusion study through research by myocardial scintigraphy in patients with panic attacks induced in the laboratory by inhalation of 35% carbon dioxide. In conclusion, from the data obtained, some hypotheses are discussed from the viewpoint of endothelial dysfunction and microvascular disease present in mental stress response.

Emergency medical service providers' role in the early heart attack care program: prevention and stratification strategies.

PubMed

MacDonald, G S; Steiner, S R

1997-01-01

Emergency Medical Services-Early Heart Attack Care (EMS-EHAC) is a community-based program where paramedics increase the consumer's awareness about early chest pain symptom recognition. EMS-EHAC prevention, along with seamless chest pain care (between the paramedic and chest pain emergency department) can be the basis for an outcome-based study to examine the impact of advanced life support EMS. Studies that show the impact of care given by paramedics on the outcome of patient care must be designed to demonstrate the value and the cost benefit of providing advanced life support (ALS). Third party payers are going to examine if there are significant quality differences between ALS and basic life support (BLS) services. If significant benefits of ALS care cannot be demonstrated, the cost differences could potentially place the future of advanced life support paramedic programs in jeopardy. A positive outcome resulting in a lower acute cardiac event, and the realization of the cost benefits from the EMS-EHAC program could be utilized by EMS management to justify or expand advanced life support programs.

Patients admitted with chest pain are a diagnostic challenge because the majority does not have coronary artery disease (CAD). Assessment of CAD with coronary computed tomography angiography (CCTA) is safe, cost-effective, and accurate, albeit with a modest specificity. Stress myocardial computed tomography perfusion (CTP) has been shown to increase the specificity when added to CCTA, without lowering the sensitivity. This article describes the design of a randomized controlled trial, CATCH-2, comparing a clinical diagnostic management strategy of CCTA alone against CCTA in combination with CTP. Patients with acute-onset chest pain older than 50 years and with at least one cardiovascular risk factor for CAD are being prospectively enrolled to this study from 6 different clinical sites since October 2013. A total of 600 patients will be included. Patients are randomized 1:1 to clinical management based on CCTA or on CCTA in combination with CTP, determining the need for further testing with invasive coronary angiography including measurement of the fractional flow reserve in vessels with coronary artery lesions. Patients are scanned with a 320-row multidetector computed tomography scanner. Decisions to revascularize the patients are taken by the invasive cardiologist independently of the study allocation. The primary end point is the frequency of revascularization. Secondary end points of clinical outcome are also recorded. The CATCH-2 will determine whether CCTA in combination with CTP is diagnostically superior to CCTA alone in the management of patients with acute-onset chest pain. Copyright © 2015 Elsevier Inc.

Chest pain is the second leading cause for emergency department (ED) visits in the United States; however, <20% of the patients have acute coronary syndrome that require immediate attention. The HEART score is designed for rapid risk stratification of ED chest pain patients using the following criteria: history, electrocardiogram, age, risk factors, and troponin. It has been shown to be superior in identifying patients with low (HEART score 0-3) and high (7-10) risk of major adverse cardiac events, who can then be rapidly discharged or admitted for intervention. This retrospective review and assessment sought to evaluate the efficacy of implementation of a Chest Pain Center (CPC) at a predominantly Asian-based community hospital in the United States. Additionally, this assessment sought to evaluate the effectiveness and safety of a HEART protocol in the first 4 months after its adoption. The facility implemented the CPC, an observation unit, in October 2016. ED physicians risk stratified patients using the HEART score. The guidelines allow ED physicians to stratify patients into 3 categories: to discharge low-risk patients, observe moderate-risk patients in the CPC, and admit high-risk patients. Patients in the CPC received additional diagnostic work-up under the care of ED physicians and cardiologists for less than 24 hours. In addition, CPC patients were followed-up 2 and 30 days after discharge. A total of 172 patients presented at the ED with a chief complaint of chest pain. The majority of the patients were classified into the moderate-risk group (n = 101). Low-risk patients spent significantly less hours in the hospital than the moderate- and high-risk groups, and the high-risk group spent more time in the hospital than the moderate-risk group. The staff followed-up with 74 CPC patients through telephone calls to assess if patients were still experiencing chest pain and if they had followed-up with a cardiologist or primary care physician. The 2- and 30-day survival rates were 100% and 97%, respectively. The data showed a significant reduction in total length of stay for all chest pain patients. This retrospective program evaluation demonstrated some evidence in using HEART score to safely risk stratify chest pain patients to the appropriate level of care. As healthcare moves from a fee-for-service environment to value-based purchasing, hospitals need to devise and implement innovative strategies to provide efficient, beneficial, and safe care for the patients.

Physical examination remains an important part of the initial evaluation of patients presenting with chest pain but little is known about the effect of patient gender on physician performance of the cardiovascular exam. To determine if resident physicians are less likely to perform five key components of the cardiovascular exam on female versus male standardized patients (SPs) presenting with acute chest pain. Videotape review of SP encounters during Objective Structured Clinical Examinations (OSCEs) administered by the Emory University Internal Medicine Residency Program in 2006 and 2007. Encounters were reviewed to assess residents' performance of five cardiac exam skills: auscultation of the aortic, pulmonic, tricuspid, and mitral valve areas and palpation for the apical impulse. One hundred forty-nine incoming residents. Residents' performance for each skill was classified as correct, incorrect, or unknown. One hundred ten of 149 (74 %) of encounters were available for review. Residents were less likely to correctly perform each of the five skills on female versus male SPs. This difference was statistically significant for auscultation of the tricuspid (p = 0.004, RR = 0.62, 95 % CI 0.46-0.83) and mitral (p = 0.007, RR = 0.58, 95 % CI = 0.41-0.83) valve regions and palpation for the apical impulse (p < 0.001, RR = 0.27, 95 % CI = 0.16-0.47). Male residents were less likely than female residents to correctly perform each maneuver on female versus male SPs. The interaction of SP gender and resident gender was statistically significant for auscultation of the mitral valve region (p = 0.006) and palpation for the apical impulse (p = 0.01). We observed significant differences in the performance of key elements of the cardiac exam for female versus male SPs presenting with chest pain. This observation represents a previously unidentified but potentially important source of gender bias in the evaluation of patients presenting with cardiovascular complaints.

The rising use of imaging cardiac stress tests has led to potentially unnecessary testing. Interventions designed to reduce inappropriate stress testing have focused on the ambulatory setting. We developed a computerized order entry tool intended to reduce the use of imaging cardiac stress tests and improve appropriate use in hospitalized patients. The tool was evaluated using preimplementation and postimplementation cohorts at a single urban academic teaching hospital. All hospitalized patients referred for testing were included. The co-primary outcomes were the use of imaging stress tests as a percentage of all stress tests and the percentage of inappropriate tests, compared between the 2 cohorts. There were 478 patients in the precohort and 463 in the postcohort. The indication was chest pain in 66% and preoperative in 18% and was not significantly different between groups. The use of nonimaging stress tests increased from 4% in the pregroup to 15% in the postgroup (p <0.001). Among very low-risk chest pain patients, the use of nonimaging stress tests increased from 7% to 25% (p <0.001). Inappropriate testing did not change significantly between groups (12% vs 11%). Inappropriate tests were most often preoperative evaluations (83%). In conclusion, our computerized ordering tool significantly increased the use of nonimaging cardiac stress tests and reduced the use of imaging tests yet was not able to reduce inappropriate use. Our study highlights the differences in cardiac stress testing between hospitalized and ambulatory patients. Copyright © 2016 Elsevier Inc. All rights reserved.

Vital signs and the rest of the physical examination were unremarkable. The electrocardiogram showed T-wave inversions and the cardiac enzymes were elevated. Angiocardiography showed an aneurysm of the right coronary artery and a thrombus formation in its distal part. Intracoronary thrombolytic therapy was attempted an oral anticoagulation was started. Further investigations did not find the cause of the aneurysmatic RCA. The patient had no further episode of chest pain. Acute coronary syndrome is a rare finding in patients under the age of 30 years. Coronary aneurysms with associated thrombus can be the cause of it. © Georg Thieme Verlag KG Stuttgart · New York.

Triage systems are used in emergency medical services to systematically prioritize prehospital resources according to individual patient conditions. Previous studies have shown cases of preventable deaths in emergency medical services even when triage systems are used, indicating a potential undertriage among some conditions. The aim of this study was to investigate the triage level among patients diagnosed with perforated peptic ulcer (PPU) or peptic ulcer bleeding (PUB). In a three-year period in Central Denmark Region, all patients hospitalized within 24 h after a 1-1-2 emergency call and who subsequently received either a PPU or a PUB (hereinafter combined and referred to as PPU/PUB) or a First Hour Quintet (FHQ: respiratory failure, stroke, trauma, cardiac chest pain, and cardiac arrest) diagnosis were investigated. A modified Poisson regression was used to estimate the relative risk of receiving the highest and lowest prehospital response level. Also, a linear regression analysis was used to estimate the relative risk of 30-day mortality. Of 8658 evaluated patients, 263 were diagnosed with PPU/PUB. After adjusting for relevant confounding variables, patients diagnosed with PPU/PUB were less likely to receive ambulance transportation compared to patients diagnosed with stroke, RR = 1.41 (CI: 1.28-1.56); trauma, RR = 1.28 (CI: 1.15-1.42); cardiac chest pain, RR = 1.47 (CI: 1.33-1.62); and cardiac arrest, RR = 1.44 (CI: 1.31-1.42). Among patients diagnosed with PPU/PUB, 6.5% (CI: 3.3-9.7) did not receive ambulance transportation. The proportion of patients not receiving ambulance transportation was higher among patients diagnosed with PPU/PUB compared to patients diagnosed with an FHQ diagnosis. The 30-day mortality rate among patients diagnosed with PPU/PUB was 7.8% (CI: 4.2-11.1). This was lower than the 30-day mortality rate among patients diagnosed with respiratory failure (P = 0.010), stroke (P = 0.001), and cardiac arrest (P < 0.001), but comparable to the 30-day mortality among patients diagnosed with cardiac chest pain (P = 0.080) and trauma (P = 0.281). Among patients calling 1-1-2, fewer patients diagnosed with PPU/PUB received ambulance transportation than patients diagnosed with FHQ diagnoses, despite a high mortality among patients diagnosed with PPU/PUB.

High-sensitivity cardiac troponin testing is used to detect myocardial damage in patients with acute chest pain. Heart-type fatty acid binding protein (H-FABP) may be an alternative, available as point-of-care test. Patients (n=203) referred by general practitioners for suspected acute coronary syndrome or presenting with typical chest pain and one major cardiovascular risk factor at the emergency department were prospectively included in a single-centre cohort study. High-sensitivity cardiac troponin T (hs-TnT) and point-of-care H-FABP testing were concomitantly performed at admission and after 6h. Maximal hs-TnT levels above the 99th percentile were observed in 152 patients (75%) with 127 (63%) fulfilling criteria for myocardial infarction. Upon admission, hs-TnT and H-FABP were associated with an area under the curve (95% CI) of 0.83 (0.77-0.89) and 0.79 (0.73-0.85), respectively, to predict myocardial infarction, which increased to 0.93 (0.90-0.97) and 0.88 (0.84-0.93), respectively, after 6h. The diagnostic accuracy for non-ST-segment elevation myocardial infarction was somewhat lower with an area under the curve (95% CI) of 0.80 (0.72-0.87), 0.90 (0.84-0.96), 0.73 (0.64-0.81) and 0.77 (0.67-0.86), respectively. When assessment was performed within 3h of chest pain onset, diagnostic accuracy of H-FABP versus hs-TnT was similar. Each standard deviation increase in admission H-FABP was associated with a 68% relative risk increase of all-cause mortality (p-value=0.027) during 666 ± 155 days of follow-up. Point-of-care H-FABP testing has lower diagnostic accuracy compared with hs-TnT assessment in patients with high pre-test acute coronary syndrome probability, but might be of interest when assessment is possible early after chest pain onset. © The European Society of Cardiology 2015.

The clinical signs of heart masses tend to be nonspecific, generally depending more on their repercussions on heart function caused by their location rather than on their type. Imaging techniques make it possible to limit the differential diagnosis of heart masses based on their location, morphology, and characteristics of echogenicity, density, or intensity, depending on the technique used to study them. We present the case of a woman with squeezing mid chest pain irradiating to her shoulder and positive cardiac markers in whom a left atrial mass was identified at echocardiography. This finding was confirmed at chest CT. The signs at chest CT were compatible with a mural hematoma and this diagnosis was confirmed after intraoperative biopsy. Copyright © 2011 SERAM.

Case report: aortic dissection and cystic medial degeneration in a 24-year-old without Marfan syndrome.

Caraang, Chris; El-Bialy, Adel

2004-12-01

The effective management of aortic dissection relies heavily on a high index of suspicion followed by timely definitive diagnosis. Young adults without a history of blunt trauma who are not at risk for atherosclerotic disease may lower this suspicion. We present a 24-year-old patient with complaints of chest pain who presented in multiple urgent care clinics and emergency departments. With a normal chest radiograph, he was repeatedly discharged home on analgesics until a loud murmur was heard. An echocardiogram revealed a dilated aortic root with an intimal flap consistent with a type II dissection. After surgical aortic repair with a Bentall procedure, he was discharged with complete relief of symptoms. Histologic reports revealed cystic medial degeneration. Physical examinations did not demonstrate the phenotypic manifestations of Marfan syndrome. This case illustrates the importance of cardiac auscultation when assessing an individual with chest pain, even with a low likelihood for alteration in arterial structure, and the maintenance of a high index of clinical suspicion despite a normal chest radiograph. We consider this case to be of interest because of its rarity in a 24-year-old.

All patients included were studied by chest auscultation, ultrasound, and x-ray upon admission to intensive care after cardiac surgery. Six lung pathologic changes and endotracheal tube malposition were found. There was a highly significant correlation between abnormalities detected by chest ultrasound and x-ray (k = 0.90), but a poor correlation between chest auscultation and x-ray abnormalities (k = 0.15). Chest auscultation may help identify endotracheal tube misplacement and tension pneumothorax but it may miss most major abnormalities. Chest ultrasound represents a valid alternative to chest x-ray to detect most postoperative abnormalities and misplacements. Copyright © 2014 Elsevier Inc. All rights reserved.

Hispanics have a high prevalence of cardiovascular risk factors, most notably type 2 diabetes. However, in a large public hospital in Houston, Texas, Hispanic patients referred for cardiac stress testing were significantly more likely to have normal test results than were Whites or non-Hispanic Blacks. We undertook an exploratory study to determine if nervios, a culturally based syndrome that shares similarities with both panic disorder and anginal symptoms, is sufficiently prevalent among Hispanics referred for cardiac testing to be considered as a possible explanation for the high probability of a normal test result. Hispanic patients were recruited consecutively when they presented for a cardiac stress test. A bilingual interviewer administered a brief medical history, the Rose Angina Questionnaire (RAQ), a questionnaire to assess a history of nervios and associated symptoms, and the PRIME-MD, a validated brief questionnaire to diagnose DSM-IV defined affective disorders. The average age of the 114 participants (38 men and 76 women) was 57 years, and the average educational attainment was 7 years. Overall, 50% of participants reported a history of chronic nervios, and 14% reported an acute subtype known as ataque de nervios. Only 2% of patients had DSM-IV defined panic disorder, and 59% of patients had a positive RAQ score (ie, Rose questionnaire angina). The acute subtype, ataque de nervios, but not chronic nervios, was related to an increased probability of having Rose questionnaire angina (P=.006). Adjusted for covariates, a positive history of chronic nervios, but not Rose questionnaire angina, was significantly associated with a normal cardiac test result (OR=2.97, P=.04). Nervios is common among Hispanics with symptoms of cardiac disease. Additional research is needed to understand how nervios symptoms differ from chest pain in Hispanics and the role of nervios in referral for cardiac workup by primary care providers and emergency room personnel.

Innervation of the mammalian esophagus.

2006-01-01

Understanding the innervation of the esophagus is a prerequisite for successful treatment of a variety of disorders, e.g., dysphagia, achalasia, gastroesophageal reflux disease (GERD) and non-cardiac chest pain. Although, at first glance, functions of the esophagus are relatively simple, their neuronal control is considerably complex. Vagal motor neurons of the nucleus ambiguus and preganglionic neurons of the dorsal motor nucleus innervate striated and smooth muscle, respectively. Myenteric neurons represent the interface between the dorsal motor nucleus and smooth muscle but they are also involved in striated muscle innervation. Intraganglionic laminar endings (IGLEs) represent mechanosensory vagal afferent terminals. They also establish intricate connections with enteric neurons. Afferent information is implemented by the swallowing central pattern generator in the brainstem, which generates and coordinates deglutitive activity in both striated and smooth esophageal muscle and orchestrates esophageal sphincters as well as gastric adaptive relaxation. Disturbed excitation/inhibition balance in the lower esophageal sphincter results in motility disorders, e.g., achalasia and GERD. Loss of mechanosensory afferents disrupts adaptation of deglutitive motor programs to bolus variables, eventually leading to megaesophagus. Both spinal and vagal afferents appear to contribute to painful sensations, e.g., non-cardiac chest pain. Extrinsic and intrinsic neurons may be involved in intramural reflexes using acetylcholine, nitric oxide, substance P, CGRP and glutamate as main transmitters. In addition, other molecules, e.g., ATP, GABA and probably also inflammatory cytokines, may modulate these neuronal functions.

To examine and compare the prevalence of coronary artery calcification (CAC) and the frequency of cardiac events in a background population and a cohort of patients with non-specific chest pain (NSCP) who present to an emergency or cardiology department and are discharged without an obvious reason for their symptom. A double-blinded, prospective, observational cohort study that measures both CT-determined CAC scores and cardiac events after 1 year of follow-up. Emergency and cardiology departments in the Region of Southern Denmark. In total, 229 patients with NSCP were compared with 722 patients from a background comparator population. Prevalence of CAC and incidence of unstable angina (UAP), acute myocardial infarction (MI), ventricular tachycardia (VT), coronary revascularisation and cardiac-related mortality 1 year after index contact. There was no significant difference in the prevalence of CAC (OR 0.9 (95% CI 0.6 to 1.3), P=0.546) or the frequency of cardiac endpoints (P=0.64) between the studied groups. When compared with the background population, the OR for patients with NSCP for a CAC >100 Agatston units (AU) was 1.0 (95% CI 0.6 to 1.5), P=0.826. During 1 year of follow-up, two (0.9%) patients with NSCP underwent cardiac revascularisation, while none experienced UAP, MI, VT or death. In the background population, four (0.6%) participants experienced a clinical cardiac endpoint; two had an MI, one had VT and one had a cardiac-related death. The prevalence of CAC (CAC >0 AU) among patients with NSCP is comparable to a background population and there is a low risk of a cardiac event in the first year after discharge. A CAC study does not provide notable clinical utility for risk-stratifying patients with NSCP.

To determine the diagnostic value of single symptoms and signs for coronary heart disease (CHD) in patients with chest pain. Searches of two electronic databases (EMBASE 1980 to March 2008, PubMed 1966 to May 2009) and hand searching in seven journals were conducted. Eligible studies recruited patients presenting with acute or chronic chest pain. The target disease was CHD, with no restrictions regarding case definitions, eg, stable CHD, acute coronary syndrome (ACS), acute myocardial infarction (MI), or major cardiac event (MCE). Diagnostic tests of interest were items of medical history and physical examination. Bivariate random effects model was used to derive summary estimates of positive (pLR) and negative likelihood ratios (nLR). We included 172 studies providing data on the diagnostic value of 42 symptoms and signs. With respect to case definition of CHD, diagnostically most useful tests were history of CHD (pLR=3.59), known MI (pLR=3.21), typical angina (pLR=2.35), history of diabetes mellitus (pLR=2.16), exertional pain (pLR=2.13), history of angina pectoris (nLR=0.42), and male sex (nLR=0.49) for diagnosing stable CHD; pain radiation to right arm/shoulder (pLR=4.43) and palpitation (pLR=0.47) for diagnosing MI; visceral pain (pLR=2.05) for diagnosing ACS; and typical angina (pLR=2.60) and pain reproducible by palpation (pLR=0.13) for predicting MCE. We comprehensively reported the accuracy of a broad spectrum of single symptoms and signs for diagnosing myocardial ischemia. Our results suggested that the accuracy of several symptoms and signs varied in the published studies according to the case definition of CHD.

5-aminosalicylic acid (mesalamine) rarely induces hypersensitivity reactions. If chest pain associated with atypical electrocardiographic changes are seen during its administration, one should always bear in mind typeIvariant of Kounis syndrome. This variant includes patients, of any age, with normal coronary arteries, without predisposing factors for coronary artery disease, in whom the acute release of inflammatory mediators from mast cells can induce either sudden coronary artery narrowing, without increase of cardiac enzymes and troponins, or coronary artery spasm that progresses to acute myocardial infarction, with elevated cardiac enzymes and troponins.

National practice guidelines recommend early aspirin administration to reduce mortality in acute coronary syndrome (ACS). Although timely administration of aspirin has been shown to reduce mortality in ACS by 23%, prior regional Emergency Medical Service (EMS) data have shown inadequate prehospital administration of aspirin in patients with suspected cardiac ischaemia. Using the National EMS Information System (NEMSIS) database, we sought to determine (1) the proportion of patients with suspected cardiac ischaemia who received aspirin and (2) patient and prehospital characteristics that independently predicted administration of aspirin. Analysis of the 2011 NEMSIS database targeted patients aged ≥40 years with a paramedic primary impression of 'chest pain'. To identify patients with chest pain of suspected cardiac aetiology, we included those for whom an ECG or cardiac monitoring had been performed. Trauma-related chest pain and basic life support transports were excluded. The primary outcome was presence of aspirin administration. Patient (age, sex, race/ethnicity and insurance status) and regional characteristics where the EMS transport occurred were also obtained. Multivariate logistic regression was used to assess the independent association of patient and regional factors with aspirin administration for suspected cardiac ischaemia. Of the total 14,371,941 EMS incidents in the 2011 database, 198,231 patients met our inclusion criteria (1.3%). Of those, 45.4% received aspirin from the EMS provider. When compared with non-Hispanic white patients, several groups had greater odds of aspirin administration by EMS: non-Hispanic black patients (OR 1.49, 95% CI 1.44 to 1.55), non-Hispanic Asians (OR 1.62, 95% CI 1.21 to 2.18), Hispanics (OR 1.71, 95% CI 1.54 to 1.91) and other non-Hispanics (OR 1.27, 95% CI 1.07 to 1.51). Patients living in the Southern region of the USA (OR 0.59, 95% CI 0.57 to 0.62) and patients with governmental (federally administered such as Veteran's Health Care, but not Medicare or Medicaid) insurance (OR 0.67, 95% CI 0.57 to 0.78) had the lowest odds of receiving aspirin. Age and sex (OR 1.00, 95% CI 1.00 to 1.00) were not associated with aspirin administration. It is likely that prehospital aspirin administration for patients with suspected cardiac ischaemia remains low nationally and could be improved. Reasons for disparities among the various groups should be explored. Published by the BMJ Publishing Group Limited.

Straight back syndrome is characterized by loss of the normal upper thoracic kyphosis, leading to a reduced anteroposterior diameter and squashing of the heart. Most patients are asymptomatic; if symptomatic, chest pain and palpitations are most common. On examination, the abnormal clinical findings simulate organic heart disease that needs to be ruled out by echocardiography and cardiac catheterization. A lateral chest radiograph is diagnostic. This condition is commonly associated with mitral valve prolapse and bicuspid aortic valve. We describe an interesting case of straight back syndrome with all the classic and rarely reported clinical findings. © The Author(s) 2014.

Delayed lead perforation: a disturbing trend.

Khan, Mohammed N; Joseph, George; Khaykin, Yaariv; Ziada, Khaled M; Wilkoff, Bruce L

2005-03-01

Delayed lead perforation (occurring more than 1 month after implantation) is a rare complication. Its pathophysiology and optimal management are currently unclear. Three cases of delayed lead perforation (6-10 month) were identified in patients with low-profile active fixation leads. All cases presented in a subacute fashion with pleuritic chest pain with confirmatory chest x-ray and device interrogation. Given the potential complications of a perforated lead, all cases had the lead extracted under TEE observation with cardiac surgery backup in the operating room. All patients tolerated extraction without complication. Based on these cases, we recommend a management scheme for patients who present with delayed lead perforation.

Angina pectoris: current therapy and future treatment options.

Parikh, Raj; Kadowitz, Philip J

2014-02-01

Angina pectoris is the consequence of an inequality between the demand and supply of blood to the heart. Angina manifests itself as chest pain or discomfort and is a common complaint of patients in the hospital and in the clinic. There are, in fact, roughly half a million new cases of angina per year. Chest pain, while having many etiologies, is generally considered to be most lethal when related to a cardiac cause. In this review, the authors outline the current medical and surgical therapies that are used in the management of angina. Highlights of the various clinical trials that have assisted in the investigation of these therapies are summarized also. Then, the authors provide a focused review of the novel therapy options for angina that are currently being explored. From new medical treatments to revised surgical techniques to the discovery of stem cell therapy, many innovative options are being investigated for the treatment of angina.

The HEART Pathway is a decision aid designed to identify emergency department patients with acute chest pain for early discharge. No randomized trials have compared the HEART Pathway with usual care. Adult emergency department patients with symptoms related to acute coronary syndrome without ST-elevation on ECG (n=282) were randomized to the HEART Pathway or usual care. In the HEART Pathway arm, emergency department providers used the HEART score, a validated decision aid, and troponin measures at 0 and 3 hours to identify patients for early discharge. Usual care was based on American College of Cardiology/American Heart Association guidelines. The primary outcome, objective cardiac testing (stress testing or angiography), and secondary outcomes, index length of stay, early discharge, and major adverse cardiac events (death, myocardial infarction, or coronary revascularization), were assessed at 30 days by phone interview and record review. Participants had a mean age of 53 years, 16% had previous myocardial infarction, and 6% (95% confidence interval, 3.6%-9.5%) had major adverse cardiac events within 30 days of randomization. Compared with usual care, use of the HEART Pathway decreased objective cardiac testing at 30 days by 12.1% (68.8% versus 56.7%; P=0.048) and length of stay by 12 hours (9.9 versus 21.9 hours; P=0.013) and increased early discharges by 21.3% (39.7% versus 18.4%; P<0.001). No patients identified for early discharge had major adverse cardiac events within 30 days. The HEART Pathway reduces objective cardiac testing during 30 days, shortens length of stay, and increases early discharges. These important efficiency gains occurred without any patients identified for early discharge suffering MACE at 30 days. URL: http://www.clinicaltrials.gov.

Background/aim: Myoglobin, cardiac troponin T, B-type natriuretic peptide (BNP), and creatine kinase isoenzyme MB (CK-MB) are frequently used biomarkers for evaluating risk of patients admitted to an emergency department with chest pain. Recently, time- dependent receiver operating characteristic (ROC) analysis has been used to evaluate the predictive power of biomarkers where disease status can change over time. We aimed to determine the best set of biomarkers that estimate cardiac death during follow-up time. We also obtained optimal cut-off values of these biomarkers, which differentiates between patients with and without risk of death. A web tool was developed to estimate time intervals in risk. Materials and methods: A total of 410 patients admitted to the emergency department with chest pain and shortness of breath were included. Cox regression analysis was used to determine an optimal set of biomarkers that can be used for estimating cardiac death and to combine the significant biomarkers. Time-dependent ROC analysis was performed for evaluating performances of significant biomarkers and a combined biomarker during 240 h. The bootstrap method was used to compare statistical significance and the Youden index was used to determine optimal cut-off values. Results : Myoglobin and BNP were significant by multivariate Cox regression analysis. Areas under the time-dependent ROC curves of myoglobin and BNP were about 0.80 during 240 h, and that of the combined biomarker (myoglobin + BNP) increased to 0.90 during the first 180 h. Conclusion: Although myoglobin is not clinically specific to a cardiac event, in our study both myoglobin and BNP were found to be statistically significant for estimating cardiac death. Using this combined biomarker may increase the power of prediction. Our web tool can be useful for evaluating the risk status of new patients and helping clinicians in making decisions.

AIM To investigate the effects of depression and anxiety on health-related quality of life (QoL) in gastroesophageal reflux disease (GERD) patients and those suffering from cardiac (CCP) and noncardiac (NCCP) chest pain in Wuhan, China. METHODS In this cross-sectional study, a total of 358 consecutive patients with GERD were enrolled in Wuhan, China, of which 176 subjects had complaints of chest pain. Those with chest pain underwent coronary angiography and were divided into a CCP group (52 cases) and NCCP group (124 cases). Validated GERD questionnaires were completed, and the 36-item Short-Form Health Survey and Hospital Anxiety/Depression Scale were used for evaluation of QoL and psychological symptoms, respectively. RESULTS There were similar ratios and levels of depression and anxiety in GERD with NCCP and CCP. However, the QoL was obviously lower in GERD with CCP than NCCP (48.34 ± 17.68 vs 60.21 ± 20.27, P < 0.01). In the GERD-NCCP group, rather than the GERD-CCP group, the physical and mental QoL were much poorer in subjects with depression and/or anxiety than those without anxiety or depression. Anxiety and depression had strong negative correlations with both physical and mental health in GERD-NCCP (all P < 0.01), but only a weak relationship with mental components of QoL in GERD-CCP. CONCLUSION High levels of anxiety and depression may be more related to the poorer QoL in GERD patients with NCCP than those with CCP. This highlights the importance of evaluation and management of psychological impact for improving QoL in GERD-NCCP patients. PMID:28104988

Prehospital Nitroglycerin in Tachycardic Chest Pain Patients: A Risk for Hypotension or Not?

The American Heart Association guidelines (AHA) guidelines list tachycardia as a contraindication for the administration of nitroglycerin (NTG), despite limited evidence of adverse events. We sought to determine whether NTG administered for chest pain was a predictor of hypotension (systolic blood pressure <90 mmHg) in patients with tachycardia, compared to patients without tachycardia (50≥ heart rate ≤100). We performed a retrospective cohort study using patient care reports completed by basic life support (BLS) providers in a large urban Canadian EMS system for the period 2010-2012. We used logistic regression to test the association between post-NTG hypotension and tachycardia, independent of pre-NTG blood pressure, age, sex, and comorbidities. Using identical models, we tested four secondary outcomes (drop in blood pressure, reduced consciousness, bradycardia, and cardiac arrest). The cohort included 10,308 patients who were administered NTG by BLS in the prehospital setting; 2,057 (20%) of patients were tachycardic before NTG administration. Hypotension occurred in 320 of all patients (3.1%): 239 without tachycardia (2.9%) and 81 with tachycardia (3.9%). Compared to non-tachycardic patients, tachycardic patients showed increased adjusted odds of hypotension (AOR: 1.60; 95% CI: 1.23-2.08) or of a drop in blood pressure of 30mm Hg or greater (AOR: 1.11; CI: 1.00-1.24). Tachycardia was associated with decreased odds of bradycardia (OR: 0.33; CI: 0.17-0.64). We did not find a significant association between tachycardia and either post-NTG reduced level of consciousness or cardiac arrest. We did find a strong, significant association between pre-NTG blood pressure and post-NTG hypotension (AOR for units of 10mmHg: 0.64; CI: 0.61-0.69). Hypotension following prehospital administration of NTG was infrequent in patients with chest pain. However, while the absolute risk of NTG-induced hypotension was low, patients with pre-NTG tachycardia had a significant increase in the relative risk of hypotension. In addition, hypotension occurred most frequently in patients presenting with a lower pre-NTG blood pressure, which may prove to be a more discriminating basis for future guidelines. EMS medical directors should review BLS chest pain protocols to weigh the benefits of NTG administration against its risks.

To assess the impact of triple marker testing on patient management and the diagnostic efficiencies of different biomarker strategies examined. A prospective randomised trial of triple marker testing by point-of-care testing (POCT); the Randomised Assessment of Panel Assay of Cardiac markers (RATPAC) study. Six emergency departments. Low-risk patients presenting with chest pain to diagnostic assessment with a cardiac panel measured by POCT or to diagnosis when biomarker measurement was based on central laboratory testing. Interventions 1125 patients were randomly assigned to POCT measurement of the triple marker panel of cardiac troponin I (cTnI), myoglobin and the MB isoenzyme of creatine kinase (CK-MB) on admission and 90 min from admission. Myocardial infarction (MI) was defined by the universal definition of MI. The following diagnostic strategies were compared by receiver operator characteristic (ROC) curve analysis and comparison of area under the curve (AUC): individual marker values, change (Δ) in CK-MB and myoglobin and the combination of presentation or 90 min value plus Δ value. Admission sample measurement of cTnI was the most diagnostically efficient AUC 0.96 (0.93-0.98) with areas under the ROC curve statistically significantly greater than CK-MB 0.85 (0.80-0.90) and myoglobin 0.75 (0.68-0.81). At 90 min cTnI measurement had the highest AUC 0.95 (0.87-1.00) but was statistically significantly different only from Δmyoglobin and ΔCK-MB. Measurement of cTnI alone is sufficient for diagnosis. Measurement of a marker panel does not facilitate diagnosis.

The HEART Pathway is a diagnostic protocol designed to identify low-risk patients presenting to the emergency department with chest pain that are safe for early discharge. This protocol has been shown to significantly decrease health care resource utilization compared with usual care. However, the impact of the HEART Pathway on the cost of care has yet to be reported. We performed a cost analysis of patients enrolled in the HEART Pathway trial, which randomized participants to either usual care or the HEART Pathway protocol. For low-risk patients, the HEART Pathway recommended early discharge from the emergency department without further testing. We compared index visit cost, cost at 30 days, and cardiac-related health care cost at 30 days between the 2 treatment arms. Costs for each patient included facility and professional costs. Cost at 30 days included total inpatient and outpatient costs, including the index encounter, regardless of etiology. Cardiac-related health care cost at 30 days included the index encounter and costs adjudicated to be cardiac-related within that period. Two hundred seventy of the 282 patients enrolled in the trial had cost data available for analysis. There was a significant reduction in cost for the HEART Pathway group at 30 days (median cost savings of $216 per individual), which was most evident in low-risk (Thrombolysis In Myocardial Infarction score of 0-1) patients (median savings of $253 per patient) and driven primarily by lower cardiac diagnostic costs in the HEART Pathway group. Using the HEART Pathway as a decision aid for patients with undifferentiated chest pain resulted in significant cost savings. Copyright © 2016 Elsevier Inc. All rights reserved.

Background Christchurch, New Zealand, was struck by 2 major earthquakes at 4:36am on 4 September 2010, magnitude 7.1 and at 12:51pm on 22 February 2011, magnitude 6.3. Both events caused widespread destruction. Christchurch Hospital was the region's only acute care hospital. It remained functional following both earthquakes. We were able to examine the effects of the 2 earthquakes on acute cardiac presentations. Methods Patients admitted under Cardiology in Christchurch Hospital 3 week prior to and 5 weeks following both earthquakes were analysed, with corresponding control periods in September 2009 and February 2010. Patients were categorised based on diagnosis: ST elevation myocardial infarction, Non ST elevation myocardial infarction, stress cardiomyopathy, unstable angina, stable angina, non cardiac chest pain, arrhythmia and others. Results There was a significant increase in overall admissions (p<0.003), ST elevation myocardial infarction (p<0.016), and non cardiac chest pain (p<0.022) in the first 2 weeks following the early morning September earthquake. This pattern was not seen after the early afternoon February earthquake. Instead, there was a very large number of stress cardiomyopathy admissions with 21 cases (95% CI 2.6–6.4) in 4 days. There had been 6 stress cardiomyopathy cases after the first earthquake (95% CI 0.44–2.62). Statistical analysis showed this to be a significant difference between the earthquakes (p<0.05). Conclusion The early morning September earthquake triggered a large increase in ST elevation myocardial infarction and a few stress cardiomyopathy cases. The early afternoon February earthquake caused significantly more stress cardiomyopathy. Two major earthquakes occurring at different times of day differed in their effect on acute cardiac events.

There was a significant increase in overall admissions (p<0.003), ST elevation myocardial infarction (p<0.016), and non cardiac chest pain (p<0.022) in the first 2 weeks following the early morning September earthquake. This pattern was not seen after the early afternoon February earthquake. Instead, there was a very large number of stress cardiomyopathy admissions with 21 cases (95% CI 2.6-6.4) in 4 days. There had been 6 stress cardiomyopathy cases after the first earthquake (95% CI 0.44-2.62). Statistical analysis showed this to be a significant difference between the earthquakes (p<0.05). The early morning September earthquake triggered a large increase in ST elevation myocardial infarction and a few stress cardiomyopathy cases. The early afternoon February earthquake caused significantly more stress cardiomyopathy. Two major earthquakes occurring at different times of day differed in their effect on acute cardiac events.

A large number of patients present to the emergency department (ED) for evaluation of acute chest pain. About 10-15% are caused by acute myocardial infarction (MI), and over 50% of cases are due to noncardiac reasons. Further improvement for chest pain evaluation appears necessary. What are current options to improve chest pain evaluation in Germany? A selective literature search was performed using the following terms: "chest pain", "emergency department", "acute coronary syndrome" and "chest pain evaluation". A working group of the German Society of Cardiology published recommendations for infrastructure, equipment and organisation of chest pain units in Germany, which should be separated from the ED of hospitals and be under the leadership of a cardiologist. A symptom-based decision for acute care would be preferable if all differential diagnoses of diseases could be managed by one medical specialty: However, all four main symptoms of patients with acute MI (chest pain, acute dyspnea, abdominal pain, dizziness) are also caused by diseases of different specialties. Evaluation and treatment of acute chest pain by representatives of one specialty would lead to over- or undertreatment of affected patients. Therefore we suggest a multidisciplinary evaluation of patients with acute chest pain including representatives of emergency and critical care physicians, cardiologists, internists, geriatricians, family physicians, premedics and emergency nurses. Definition of key indicators of performance and institutionalized feedback will help to further improve quality of care.

A single-centre report on the characteristics of Tako-tsubo syndrome.

Tako-tsubo cardiomyopathy is an increasingly recognised phenomenon characterised by chest pain, ECG abnormalities, cardiac biomarker elevation and transient left ventricular dysfunction without significant coronary artery obstruction. To report the clinical and echocardiographic characteristics from a large single-centre Australian series of patients with Tako-tsubo syndrome. We prospectively collected data on 23 consecutive patients presenting between November 2005 and November 2007. Baseline demographics, ECG, echocardiography and coronary angiography were performed on nearly all patients. All patients presented with chest pain; 87% were female. Various stressors were noted and cardiac Troponin-T was elevated in 91% of patients. All patients had non-obstructive coronary disease at angiography. 19/23 patients had initial and subsequent echocardiography. Mean ejection fraction was 50% at baseline and 64% at follow-up (p<0.0001). Right ventricular dysfunction was present in eight, dynamic left ventricular outflow tract obstruction in two, diastolic dysfunction in seven and two patients had the mid-cavity variant. This large prospective single-centre Australian series of Tako-tsubo syndrome is in concert with previous published series. Complete recovery of left ventricular function on echocardiographic follow-up was typical. Although its pathogenesis remains unclear, early distinction from acute coronary syndromes is important and the prognosis is reassuringly good. Crown Copyright (c) 2009. Published by Elsevier B.V.

Resolution of Tachyarrhythmia Following Posterior Fossa Decompression Surgery for Chiari Malformation Type I.

PubMed

Elia, Christopher; Brazdzionis, James; Tashjian, Vartan

2018-03-01

Chiari malformation (CM) type I commonly presents with symptoms such as tussive headaches, paresthesias, and, in severe cases, corticobulbar dysfunction. However, patients may present with atypical symptoms lending to the complexity in this patient population. We present a case of a CM patient presenting with atypical cardiac symptoms and arrhythmias, all of which resolved after surgical decompression. A 31-year-old female presented with atypical chest pain, palpitations, tachycardia, headaches, and dizziness for 2 years. Multiple antiarrhythmics and ultimately cardiac ablation procedure proved to be ineffective. Magnetic resonance imaging revealed CM, and the patient ultimately underwent surgical decompression with subsequent resolution of her symptoms. The surgical management of CM patients presenting with atypical symptoms can be challenging and often lead to delays in intervention. To our knowledge this is the only reported case of a patient presenting with tachyarrhythmia and atypical chest pain with resolution after Chiari decompression. We believe the dramatic improvement documented in the present case should serve to advance Chiari decompression in CM patients presenting with refractory tachyarrhythmia in whom no other discernable cause has been elucidated. Further studies are needed to better correlate the findings and to hopefully establish a criteria for patients that will likely benefit from surgical decompression. Copyright © 2017 Elsevier Inc.

Prepartum or postpartum right ventricular thrombosis (RVT) is an exceedingly rare and potentially lethal phenomenon in pregnancy. We here report a case of a pregnant patient with near term pregnancy admitted for dyspnea, amniotic fluids discharge and labor pain in a gynecology center that an eight-month dead fetus was diagnosed and delivered vaginally by induction. A post delivery period was complicated by aggravation of her dyspnea and pleuritic chest pain that she referred for further evaluation in our cardiac center. Physical exam revealed normal head and neck exam, and history taking revealed that her fetus had intra-uterine growth failure as reported by her gynecologist. Chest exam except to left lung crackle was normal. Lower and upper left extremities were normal. However, acrocyanosis was found in tips of 4 and 5th right-hand digits. Chest x-ray revealed some linear consolidation in left lower lung lobes, and the precordial exam was normal. ECG was normal. Post delivery transthoracic echocardiography (TEE) showed a 1.5×1.5 cm mobile right ventricular clot. C-T angiography revealed obstruction of left upper lung pulmonary artery branches. Complete thrombophilia assay showed the presence of high titer of antiphospholipid, anticardiolipin antibody, and β1 glycoprotein antibody. However, others test were normal. The patient was scheduled for cardiac surgery, and her hemodynamic was monitored by left radial artery line and central pressure venous line, and thrombus was removed from the right ventricle (RV), and subsequent anticoagulation therapy constituted. Six-month follow-up revealed no recurrence of thrombus and recovery of patient's symptoms.

The association between ethnicity and delay in seeking medical care for chest pain: a systematic review.

PubMed

Wechkunanukul, Kannikar; Grantham, Hugh; Damarell, Raechel; Clark, Robyn A

2016-07-01

Acute coronary syndrome (ACS) is a leading cause of mortality and morbidity worldwide, and chest pain is one of the most common symptoms of ACSs. A rapid response to chest pain by patients and appropriate management by health professionals are vital to improve survival rates.People from different ethnic groups are likely to have different perceptions of chest pain, its severity and the need for urgent treatment. These differences in perception may contribute to differences in response to chests pain and precipitate unique coping strategies. Delay in seeking medical care for chest pain in the general population has been well documented; however, limited studies have focused on delay times within ethnic groups. There is little research to date as to whether ethnicity is associated with the time taken to seek medical care for chest pain. Consequently, addressing this gap in knowledge will play a crucial role in improving the health outcomes of culturally and linguistically diverse (CALD) patients suffering from chest pain and for developing appropriate clinical practice and public awareness for these populations. The current review aimed to determine if there is an association between ethnicity and delay in seeking medical care for chest pain among CALD populations. Patients from different ethnic minority groups presenting to emergency departments (EDs) with chest pain. The current review will examine studies that evaluate the association between ethnicity and delay in seeking medical care for chest pain among CALD populations. The current review will consider quantitative studies including randomized controlled trials (RCTs), non-RCTs, quasi-experimental, before and after studies, prospective and retrospective cohort studies, case-control studies and analytical cross-sectional studies. The current review will consider studies that measure delay time as the main outcome. The time will be measured as the interval between the time of symptom onset and time to reach an ED. A comprehensive search was undertaken for relevant published and unpublished studies written in English with no date restriction. All searches were conducted in October 2014. We searched the following databases: MEDLINE, PubMed, Cochrane Central Register of Controlled Trials, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, ProQuest (health databases only), Informit, Sociological Abstracts, Scopus and Web of Science. The search for unpublished studies included a wide range of 'gray literature' sources including national libraries, digital theses repositories and clinical trial registries. We also targeted specific health research, specialist cardiac, migrant health, and emergency medicine organizational websites and/or conferences. We also checked the reference lists of included studies and contacted authors when further details about reported data was required to make a decision about eligibility. Papers selected for retrieval were assessed by two independent reviewers for methodological validity prior to being included in the review. Validity was assessed using standardized critical appraisal instruments from the Joanna Briggs Institute. Adjudication was produced by the third reviewer. Data were extracted from included articles by two independent reviewers using the standardized data extraction tool from the Joanna Briggs Institute. The extracted data were synthesized into a narrative summary. Meta-analysis could not be performed due to the heterogeneity of study protocols and methods used to measure outcomes. A total of 10 studies, with a total of 1,511,382 participants, investigating the association between ethnicity and delay met the inclusion criteria. Delay times varied across ethnic groups, including Black, Hispanic, Asian, South Asian, Southeast Asian and Chinese. Seven studies reported delay in hours and ranged from 1.90 to 3.10 h. Delay times were longer among CALD populations than the majority population. The other three studies reported delay time in categories of time (e.g. <1, <4 and <6 h) and found larger proportions of later presentations to the EDs among ethnic groups compared with the majority groups. There is evidence of an association between ethnicity and time taken in seeking medical care for chest pain, with patients from some ethnic minorities (e.g. Black, Asian, Hispanic and South Asian) taking longer than those of the majority population. Health promotions and health campaigns focusing on these populations are indicated.

Pulmonary embolism presenting with itinerant chest pain and migratory pleural effusion: A case report.

Li, Wei; Chen, Chen; Chen, Mo; Xin, Tong; Gao, Peng

2018-06-01

Pulmonary embolism (PE) presents with complex clinical manifestations ranging from asymptomatic to chest pain, hemoptysis, syncope, shock, or sudden death. To the authors' knowledge, itinerant chest pain has not been reported as sign or symptom of PE. A 41-year-old woman presenting with left chest pain, no hemoptysis, or breathing difficulties. The chest pain was more severe on deep inspiration. Chest computed tomography (CT) and ultrasound imaging showed left pleural effusion. After antibiotic treatment, the left chest pain was alleviated, but a similar pain appeared in the right chest. Electrocardiogram, blood gas analysis, echocardiography, and D-dimer levels were unremarkable. Chest CT showed right pleural effusion. A CT pulmonary angiography (CTPA) unexpectedly revealed a PE in the right pulmonary artery. The patient was administered anticoagulant therapy and made a complete recovery. The use of CTPA to investigate the possible presence of PE in patients with unexplained migratory pleural effusion complaining of itinerant chest pain is important. Lessons should be learned from the early use of CTPA to investigate the possible presence of PE in patients.

A 52-year-old man presented with altered mental status and report of prior complaint of chest pain. On electrocardiography, anterolateral ST-segment elevations with Q-waves in the septal leads were seen. Initial echocardiography images demonstrated a thickened anteroseptum. Further imaging showed the presence of a well-attached laminated apical thrombus. Contrast echocardiography images showed that the thrombus had minimal attachment to the endocardial surface. CT head subsequently showed the presence of acute stroke. The case demonstrates the additional value of contrast echocardiography in the evaluation of cardiac masses despite the certainty in the diagnosis of a thrombus. © 2017, Wiley Periodicals, Inc.

A massive haemothorax as an unusual complication of infective endocarditis caused by Streptococcus sanguinis.

PubMed

Kim, Kyoung Jin; Lee, Kang Won; Choi, Ju Hee; Sohn, Jang Wook; Kim, Min Ja; Yoon, Young Kyung

2016-08-01

Infective endocarditis involving the tricuspid valve is an uncommon condition, and a consequent haemothorax associated with pulmonary embolism is extremely rare. Particularly, there are no guidelines for the management of this complication. We describe a rare case of pulmonary embolism and infarction followed by a haemothorax due to infective endocarditis of the tricuspid valve caused by Streptococcus sanguinis. A 25-year-old man with a ventricular septal defect (VSD) presented with fever. On physical examination, his body temperature was 38.8 °C, and a grade III holosystolic murmur was heard. A chest X-ray did not reveal any specific findings. A transoesophageal echocardiogram showed a perimembranous VSD and echogenic material attached to the tricuspid valve. All blood samples drawn from three different sites yielded growth of pan-susceptible S. sanguinis in culture bottles. On day 12 of hospitalization, the patient complained of pleuritic chest pain without fever. Physical examination revealed reduced breathing sounds and dullness in the lower left thorax. On his chest computed tomography scan, pleural effusion with focal infarction and pulmonary embolism were noted on the left lower lung. Thoracentesis indicated the presence of a haemothorax. Our case was successfully treated using antibiotic therapy alone with adjunctive chest tube insertion, rather than with anticoagulation therapy for pulmonary embolism or cardiac surgery. When treating infective endocarditis caused by S. sanguinis, clinicians should include haemothorax in the differential diagnosis of patients complaining of sudden chest pain.

Stress myocardial perfusion imaging in the emergency department--new techniques for speed and diagnostic accuracy.

PubMed

Harrison, Sheri D; Harrison, Mark A; Duvall, W Lane

2012-05-01

Emergency room evaluations of patients presenting with chest pain continue to rise, and these evaluations which often include cardiac imaging, are an increasing area of resource utilization in the current health system. Myocardial perfusion imaging from the emergency department remains a vital component of the diagnosis or exclusion of coronary artery disease as the etiology of chest pain. Recent advances in camera technology, and changes to the imaging protocols have allowed MPI to become a more efficient way of providing this diagnostic information. Compared with conventional SPECT, new high-efficiency CZT cameras provide a 3-5 fold increase in photon sensitivity, 1.65-fold improvement in energy resolution and a 1.7-2.5-fold increase in spatial resolution. With stress-only imaging, rest images are eliminated if stress images are normal, as they provide no additional prognostic or diagnostic value and cancelling the rest images would shorten the length of the test which is of particular importance to the ED population. The rapid but accurate triage of patients in an ED CPU is essential to their care, and stress-only imaging and new CZT cameras allow for shorter test time, lower radiation doses and lower costs while demonstrating good clinical outcomes. These changes to nuclear stress testing can allow for faster throughput of patients through the emergency department while providing a safe and efficient evaluation of chest pain.

Objectives To compare outcomes and cost-effectiveness of various initial imaging strategies in the management of stable chest pain in a long-term prospective randomised trial. Setting Regional cardiothoracic referral centre in the east of England. Participants 898 patients (69% man) entered the study with 869 alive at 2 years of follow-up. Patients were included if they presented for assessment of stable chest pain with a positive exercise test and no prior history of ischaemic heart disease. Exclusion criteria were recent infarction, unstable symptoms or any contraindication to stress MRI. Primary outcome measures The primary outcomes of this follow-up study were survival up to a minimum of 2 years post-treatment, quality-adjusted survival and cost-utility of each strategy. Results 898 patients were randomised. Compared with angiography, mortality was marginally higher in the groups randomised to cardiac MR (HR 2.6, 95% CI 1.1 to 6.2), but similar in the single photon emission CT-methoxyisobutylisonitrile (SPECT-MIBI; HR 1.0, 95% CI 0.4 to 2.9) and ECHO groups (HR 1.6, 95% CI 0.6 to 4.0). Although SPECT-MIBI was marginally superior to other non-invasive tests there were no other significant differences between the groups in mortality, quality-adjusted survival or costs. Conclusions Non-invasive cardiac imaging can be used safely as the initial diagnostic test to diagnose coronary artery disease without adverse effects on patient outcomes or increased costs, relative to angiography. These results should be interpreted in the context of recent advances in imaging technology. Trial registration ISRCTN 47108462, UKCRN 3696. PMID:24508847

Diagnostic evaluation of the MRP-8/14 for the emergency assessment of chest pain.

Elevated levels of myeloid-related protein (MRP)-8/14 (S100A8/A9) are associated with first cardiovascular events in healthy individuals and worse prognosis in patients with acute coronary syndrome (ACS). The diagnostic utility of MRP-8/14 in patients presenting to the emergency room with symptoms concerning for ACS is uncertain. MRP-8/14 was measured in serial serum and plasma samples in a single center prospective cohort-study of patients presenting to the emergency room with non-traumatic chest pain concerning for ACS. Final diagnosis was adjudicated by an endpoint committee. Of patients with baseline MRP-8/14 results (n = 411), the median concentration in serum was 1.57 μg/ml (25th, 75th: 0.87, 2.68) and in plasma was 0.41 μg/ml (<0.4, 1.15) with only moderate correlation between serum and plasma (ρ = 0.40). A final diagnosis of MI was made in 106 (26%). Peak serum MRP-8/14 was higher in patients presenting with MI (p < 0.001). However, the overall diagnostic performance of MRP-8/14 was poor: sensitivity 28% (95% CI 20-38), specificity 82% (78-86), positive predictive value 36% (26-47), and negative predictive value 77% (72-81). The area under the ROC curve for diagnosis of MI with MRP-8/14 was 0.55 (95% CI 0.51-0.60) compared with 0.95 for cTnI. The diagnostic performance was not improved in early-presenters, patients with negative initial cTnI, or using later MRP-8/14 samples. Patients presenting with MI had elevated levels of serum MRP-8/14 compared to patients with non-cardiac chest pain. However, overall diagnostic performance of MRP-8/14 was poor and neither plasma nor serum MRP-8/14 offered diagnostic utility comparable to cardiac troponin.

Fulminant fatal swine influenza (H1N1): Myocarditis, myocardial infarction, or severe influenza pneumonia?

PubMed

Cunha, Burke A; Syed, Uzma; Mickail, Nardeen

2010-01-01

The swine influenza (H1N1) pandemic began in Mexico and rapidly spread worldwide. As is the case with pandemic influenza A, the majority of early deaths have been in young healthy adults. The complications of pandemic H1N1 have been reported from several centers. Noteworthy has been the relative rarity of bacterial coinfection in bacterial pneumonia in hospitalized adults with H1N1 pneumonia. Simultaneous bacterial community-acquired pneumonia due to methicillin-sensitive Staphylococcus aureus or community-acquired methicillin resistant S. aureus and subsequent bacterial community-acquired pneumonia due to S. pneumoniae or Haemophilus influenzae have been reportedly rare (0.4%-4% of well-documented cases). Cardiac complications of H1N1 infection have been uncommon. Young healthy adults without a cardiac history who have H1N1 and chest pain usually have either acute myocardial infarction or acute myocarditis. Cardiac symptomatology with H1N1 often overshadows pulmonary manifestations, that is, influenza pneumonia. With H1N1 pneumonia, clinicians should be alert for otherwise unexplained tachycardia or chest pain that may represent acute myocardial infarction or myocarditis. We present a case of rapidly fatal H1N1 in a young adult treated with oseltamivir and peramivir. He was initially tachycardic, thought to represent myocarditis. He subsequently became hypotensive and expired. At autopsy there was cardiomegaly present but there were no signs of acute myocardial infarction or myocarditis. Pathologically, he died of severe H1N1 pneumonia and not bacterial pneumonia. Copyright © 2010 Elsevier Inc. All rights reserved.

To analyse the implementation, applicability and accuracy of the pretest probability calculation provided by NICE clinical guideline 95 for decision making about imaging in patients with chest pain of recent onset. The definitions for pretest probability calculation in the original Duke clinical score and the NICE guideline were compared. We also calculated the agreement and disagreement in pretest probability and the resulting imaging and management groups based on individual patient data from the Collaborative Meta-Analysis of Cardiac CT (CoMe-CCT). 4,673 individual patient data from the CoMe-CCT Consortium were analysed. Major differences in definitions in the Duke clinical score and NICE guideline were found for the predictors age and number of risk factors. Pretest probability calculation using guideline criteria was only possible for 30.8 % (1,439/4,673) of patients despite availability of all required data due to ambiguity in guideline definitions for risk factors and age groups. Agreement regarding patient management groups was found in only 70 % (366/523) of patients in whom pretest probability calculation was possible according to both models. Our results suggest that pretest probability calculation for clinical decision making about cardiac imaging as implemented in the NICE clinical guideline for patients has relevant limitations. • Duke clinical score is not implemented correctly in NICE guideline 95. • Pretest probability assessment in NICE guideline 95 is impossible for most patients. • Improved clinical decision making requires accurate pretest probability calculation. • These refinements are essential for appropriate use of cardiac CT.

Predicting Chest Wall Pain From Lung Stereotactic Body Radiotherapy for Different Fractionation Schemes

DOE Office of Scientific and Technical Information (OSTI.GOV)

Woody, Neil M.; Videtic, Gregory M.M.; Stephans, Kevin L.

Purpose: Recent studies with two fractionation schemes predicted that the volume of chest wall receiving >30 Gy (V30) correlated with chest wall pain after stereotactic body radiation therapy (SBRT) to the lung. This study developed a predictive model of chest wall pain incorporating radiobiologic effects, using clinical data from four distinct SBRT fractionation schemes. Methods and Materials: 102 SBRT patients were treated with four different fractionations: 60 Gy in three fractions, 50 Gy in five fractions, 48 Gy in four fractions, and 50 Gy in 10 fractions. To account for radiobiologic effects, a modified equivalent uniform dose (mEUD) model calculatedmore » the dose to the chest wall with volume weighting. For comparison, V30 and maximum point dose were also reported. Using univariable logistic regression, the association of radiation dose and clinical variables with chest wall pain was assessed by uncertainty coefficient (U) and C statistic (C) of receiver operator curve. The significant associations from the univariable model were verified with a multivariable model. Results: 106 lesions in 102 patients with a mean age of 72 were included, with a mean of 25.5 (range, 12-55) months of follow-up. Twenty patients reported chest wall pain at a mean time of 8.1 (95% confidence interval, 6.3-9.8) months after treatment. The mEUD models, V30, and maximum point dose were significant predictors of chest wall pain (p < 0.0005). mEUD improved prediction of chest wall pain compared with V30 (C = 0.79 vs. 0.77 and U = 0.16 vs. 0.11). The mEUD with moderate weighting (a = 5) better predicted chest wall pain than did mEUD without weighting (a = 1) (C = 0.79 vs. 0.77 and U = 0.16 vs. 0.14). Body mass index (BMI) was significantly associated with chest wall pain (p = 0.008). On multivariable analysis, mEUD and BMI remained significant predictors of chest wall pain (p = 0.0003 and 0.03, respectively). Conclusion: mEUD with moderate weighting better predicted chest wall pain than did V30, indicating that a small chest wall volume receiving a high radiation dose is responsible for chest wall pain. Independently of dose to the chest wall, BMI also correlated with chest wall pain.« less

The aim of the research is to determine the effect of cold application on the pain owing to chest tube removal for patients with single pleural chest tube. Removal of chest tubes causes patients to feel pain and interventions used for reducing the pain owing to the removal of chest tubes are not sufficient. Controlled clinical trial with repeated measures. This study was conducted with 140 patients, of whom 70 patients were in the experimental group and 70 patients were in the control group, in a thoracic hospital in Turkey. Data were collected using a data collection form consisting of patients' demographic and health history and Visual Analogue Scale. Cold was applied to patients in the experimental group prior to chest tube removal. In the experimental group, skin temperature and pain intensity was measured for each patient at four time points. In the control group, pain intensity was evaluated for each patient at three time points. Data were evaluated using Chi-square and Repeated Measurements two-way anova tests. The Visual Analogue Scale score was measured immediately after the chest tube removal in the experimental group was 3·85, compared with 5·60 in the control group. There were significant differences on pain with cold application between the two groups prior and after the intervention. Age, gender, the number of days the chest tube was inserted and the chest tube insertion indication had no effect on the pain owing to chest tube removal. Cold application is effective in reducing the pain owing to chest tube removal. Cold application was recommended prior to chest tube removal to reduce the pain owing to removal of chest tube. © 2011 Blackwell Publishing Ltd.

Physical activity is an essential lifestyle intervention for the patient with existing cardiovascular disease. National guidelines describe the importance of and define the minimal doses of daily physical activity including walking 10,000 steps a day (equivalent to 5 miles) or performing 30 minutes of moderate-intensity aerobic activity most days of the week in 10- to 15-minute bouts. However, cardiac patients are often fearful that increasing physical activity would be detrimental and cause chest pain or myocardial infarction. Research has shown that cardiac patients can perform a walking program safely. Patient education; development of a realistic plan; measurement of the frequency, intensity, duration, and type of physical activity attained; and consistent follow-up over time are key strategies. This article provides important information for healthcare providers to plan a safe and efficacious walking plan to increase physical activity in the cardiac patient.

For those living with Kawasaki disease and coronary artery aneurysms, little is known about the psychosocial burden faced by parents and their children. Exploratory, descriptive, mixed-methods design examining survey and interview data about health-related uncertainty, intrusiveness, and self-efficacy. Parents' uncertainty was associated with missed diagnosis, higher income, and maternal education. Higher uncertainty scores among children were associated with absence of chest pain and lower number of echocardiograms. High intrusiveness scores among parents were associated with previous cardiac catheterization, use of anticoagulants, lower parent education and income, and missed diagnosis. High intrusiveness scores among children were associated with high paternal education. Children's total self-efficacy scores increased with chest pain and larger aneurysm size. Qualitative analysis showed two central themes: Psychosocial Struggle and Cautious Optimism. Negative illness impact is associated with a more intense medical experience and psychosocial limitations. Timely assessment and support are warranted to meet parents' and children's needs. Copyright © 2016 National Association of Pediatric Nurse Practitioners. Published by Elsevier Inc.

In recent years, coronary computed tomography angiography has become an increasingly safe and noninvasive modality for the evaluation of the anatomical structure of the coronary artery tree with diagnostic benefits especially in patients with a low-to-intermediate pretest probability of disease. Currently, increasing evidence from large randomized diagnostic trials is accumulating on the diagnostic impact of computed tomography angiography for the management of patients with acute and stable chest pain syndrome. At the same time, technical advances have substantially reduced adverse effects and limiting factors, such as radiation exposure, the amount of iodinated contrast agent, and scanning time, rendering the technique appropriate for broader clinical applications. In this work, we review the latest developments in computed tomography technology and describe the scientific evidence on the use of cardiac computed tomography angiography to evaluate patients with acute and stable chest pain syndrome.

Recent Advances in Noncardiac Chest Pain in Korea

PubMed Central

Kim, Jeong Hwan

2012-01-01

Gastroesophageal reflux disease (GERD) is the most common cause of noncardiac chest pain (NCCP) and is present in up to 60% of patients with NCCP in Western countries. In Korea, after a reasonable cardiac evaluation, GERD is reported to underlie 41% of NCCP cases. Typical reflux symptoms are frequent in Korean patients suffering from NCCP. Therefore, a careful history of the predominant symptoms, including heartburn and acid regurgitation, is relatively indicative of the GERD diagnosis in Korea. In Korea, in contrast to Western countries, patients aged 40 years and over who have been diagnosed with NCCP but who are without alarming features should undergo endoscopy to exclude gastric cancer or peptic ulcers because of the higher prevalence of peptic ulcer disease and gastric cancers in the region. In a primary care setting, in the absence of any alarming symptoms, a symptomatic response to a trial of a proton pump inhibitor (PPI) is sufficient for the presumptive diagnosis of GERD. In addition, the optimal duration of a PPI test may be at least 2 weeks, as GERD symptoms tend to be less frequent or atypical in Korean patients than in patients from Western countries. In patients diagnosed with GERD-related NCCP, long-term therapy (more than 2 months) with double the standard dose of a PPI is required to alleviate symptoms. Esophageal dysmotility is relatively uncommon, and pain modulators seem to offer significant improvement of chest pain control in non-GERD-related NCCP. Most traditionally available tricyclics or heterocyclics have many undesirable effects. Therefore, newer drugs with fewer side effects (for example, the serotonin - norepinephrine reuptake inhibitors) may be needed. PMID:22375165

Myopericarditis has occasionally been reported as a side effect of mesalamine in patients with inflammatory bowel disease. We present a 20-year-old woman with ulcerative colitis admitted with chest pain. After thorough investigation she was diagnosed with myopericarditis potentially related to mesalamine. There was complete clinical and laboratorial recovery following drug withdrawal. Although uncommon, the possibility of myopericarditis should be considered in patients with inflammatory bowel disease presenting with cardiac complaints. Early recognition can avoid potential life-threatening complications.

Measuring cardiac troponins is integral to diagnosing acute myocardial infarction (AMI); however, troponins may be elevated without AMI, and the use of multiple different assays confounds comparisons. We considered characteristics and serial troponin values in emergency department chest pain patients with and without AMI to interpret troponin excursions. We compared serial troponin in 124 AMI and non-AMI patients from the observational Performance of Triage Cardiac Markers in the Clinical Setting (PEARL) study who presented with chest pain and had at least one troponin value exceeding the 99th percentile of normal. Because 8 assays were used during data collection, we employed a method of scaling the troponin value to the corresponding assay's 99th percentile upper reference limit to standardize the results. In 81 AMI patients, 96% had elevated troponin at the first test following initial elevation, compared to 73% of the 43 non-AMI patients (P < 0.001). Scaling troponin to the 99th percentile of normal yielded a median value that was 4.8 [2.2, 14.1] times higher than the 99th percentile cutpoint among AMI patients, compared to 2.3 [1.5, 6.5] times higher among non-AMI patients (P = 0.04). The rise in serial scaled troponin values distinguished the AMI patients. Scaling to the 99th percentile was useful for comparing troponin when different assays were utilized. PMID:28127121

Patient: Male, 51 Final Diagnosis: ST-segment elevation myocardial infarction with acute stent thrombosis Symptoms: Chest pain • hiccups Medication: — Clinical Procedure: — Specialty: Cardiology Objective: Unusual clinical course Background: Acute coronary syndrome (ACS) can present with atypical chest pain or symptoms not attributed to heart disease, such as indigestion. Hiccups, a benign and self-limited condition, can become persistent or intractable with overlooked underlying etiology. There are various causes of protracted hiccups, including metabolic abnormalities, psychogenic disorders, malignancy, central nervous system pathology, medications, pulmonary disorders, or gastrointestinal etiologies. It is rarely attributed to cardiac disease. Case Report: We report a case of intractable hiccups in a 51-year-old male with cocaine related myocardial infarction (MI) before and after stent placement. Coronary angiogram showed in-stent thrombosis of the initial intervention. Following thrombectomy, balloon angioplasty, and stent, the patient recovered well without additional episodes of hiccups. Although hiccups are not known to present with a predilection for a particular cause of myocardial ischemia, this case may additionally be explained by the sympathomimetic effects of cocaine, which lead to vasoconstriction of coronary arteries. Conclusions: Hiccups associated with cardiac enzyme elevation and EKG ST-segment elevation before and after percutaneous coronary intervention (PCI) maybe a manifestation of acute MI with or without stent. The fact that this patient was a cocaine user may have contributed to the unique presentation. PMID:28455489

In August 2006, the new AZ Alkmaar soccer stadium (capacity 17,000) opened. To provide adequate emergency support, medical teams of Red Cross volunteers and coronary care unit and emergency room nurses were formed, and facilities including automated external defibrillators were made available at the stadium. During every match, 3 teams are placed among the spectators. All patients who had cardiac events were stabilized by the teams and transported to the hospital. They formed the study group. From August 2006 to May 2007, >800,000 individuals attended soccer matches at the new stadium. Four cardiac events (3 out-of-hospital-resuscitations for ventricular fibrillation, 1 patient with chest pain) requiring emergency medical support occurred. On-site resuscitations using defibrillators were successful. Two patients with triple-vessel disease subsequently underwent coronary bypass surgery and implantable cardioverter-defibrillator implantation. One patient had single-vessel disease of the circumflex branch, for which he received a coronary stent. All had uneventful recoveries. An acute coronary syndrome was ruled out in the patient presenting with chest pain. In conclusion, the presence of emergency medical teams at a large sport stadium was of vital importance in the immediate care of critically ill patients. On-site resuscitation using automated external defibrillators was lifesaving in all cases. The presence of medical teams equipped with defibrillators and emergency action plans is recommended at large venues that host sports and other activities.

Nonrheumatic myopericarditis is an uncommon complication of acute pharyngitis caused by Group A Streptococcal infection (GAS). While the natural history of carditis complicating acute rheumatic fever is well established, the incidence, pathophysiology and clinical course of nonrheumatic myopericarditis are ill defined. Advances in rapid bedside testing for both myocardial injury and GAS pharyngitis have allowed for increasing recognition of this uncommon complication in patients presenting with a sore throat with associated chest discomfort. We describe a case of a 34years old man with GAS pharyngitis complicated by acute myopericarditis who presented with chest pain, ST segment elevation on electrocardiogram, and elevated cardiac biomarkers.

Cardiac life support is a form of first aid for cardiac emergencies. However, research and evidence in this field is lacking compared with other forms of first aid. Having identified the common emergencies that are encountered in the hospital, based on the available evidence, we have put together what could be an evidence-based approach to the first aid management of some of these common emergencies, viz. breathlessness, chest pain, allergies, stroke, heat injury, poisoning, unconsciousness, seizures, and trauma situations such as bleeding, wounds, contusions, head injury, burns and fractures. Educating the public is the key to developing a first responder bystander. These guidelines could become the basis for training of the public. Copyright: © Singapore Medical Association.

Bleeding into the chest is a major cause of blood transfusion and adverse outcomes following cardiac surgery. The authors investigated predictors of bleeding following cardiac surgery to identify potentially correctable factors. Data were retrieved from the medical records of patients undergoing cardiac surgery over the period of 2002 to 2008. Multivariate analysis was used to identify the independent predictors of chest tube drainage. Tertiary hospital. Two thousand five hundred seventy-five patients. Cardiac surgery. The individual operating surgeon was independently associated with the extent of chest tube drainage. Other independent factors included internal mammary artery grafting, cardiopulmonary bypass time, urgency of surgery, tricuspid valve surgery, redo surgery, left ventricular impairment, male gender, lower body mass index and higher preoperative hemoglobin levels. Both a history of diabetes and administration of aprotinin were associated with reduced levels of chest tube drainage. The individual operating surgeon was an independent predictor of the extent of chest tube drainage. Attention to surgeon-specific factors offers the possibility of reduced bleeding, fewer transfusions, and improved patient outcomes. © 2014 The Authors. Published by Elsevier Inc.

Hypnotherapy is an evidence based intervention for the treatment of functional bowel disorders, particularly irritable bowel syndrome. While similar in pathophysiology, less is known about the utility of hypnotherapy in the upper gastrointestinal tract. Esophageal disorders, most of which are functional in nature, cause painful and uncomfortable symptoms that impact patient quality of life and are difficult to treat from a medical perspective. After a thorough medical workup and a failed trial of proton pump inhibitor therapy, options for treatment are significantly limited. While the pathophysiology is likely multifactorial, two critical factors are believed to drive esophageal symptoms--visceral hypersensitivity and symptom hypervigilance. The goal of esophageal directed hypnotherapy is to promote a deep state of relaxation with focused attention allowing the patient to learn to modulate physiological sensations and symptoms that are not easily addressed with conventional medical intervention. Currently, the use of hypnosis is suitable for dysphagia, globus, functional chest pain/non-cardiac chest pain, dyspepsia, and functional heartburn. In this article the authors will provide a rationale for the use of hypnosis in these disorders, presenting the science whenever available, describing their approach with these patients, and sharing a case study representing a successful outcome.

High-sensitivity troponin assays have improved the diagnosis of acute coronary syndrome in patients presenting with chest pain and normal troponin levels as measured by conventional assays. Our aim was to investigate whether N-terminal pro-brain natriuretic peptide provides additional information to troponin determination in these patients. A total of 398 patients, included in the PITAGORAS study, presenting to the emergency department with chest pain and normal troponin levels as measured by conventional assay in 2 serial samples (on arrival and 6 h to 8h later) were studied. The samples were also analyzed in a central laboratory for high-sensitivity troponin T (both samples) and for N-terminal pro-brain natriuretic peptide (second sample). The endpoints were diagnosis of acute coronary syndrome and the composite endpoint of in-hospital revascularization or a 30-day cardiac event. Acute coronary syndrome was adjudicated to 79 patients (20%) and the composite endpoint to 59 (15%). When the N-terminal pro-brain natriuretic peptide quartile increased, the diagnosis of acute coronary syndrome also increased (12%, 16%, 23% and 29%; P=.01), as did the risk of the composite endpoint (6%, 13%, 16% and 24%; P=.004). N-terminal pro-brain natriuretic peptide elevation (>125ng/L) was associated with both endpoints (relative risk= 2.0; 95% confidence interval, 1.2-3.3; P=.02; relative risk=2.4; 95% confidence interval, 1.4-4.2; P=.004). However, in the multivariable models adjusted by clinical and electrocardiographic data, a predictive value was found for high-sensitivity T troponin but not for N-terminal pro-brain natriuretic peptide. In low-risk patients with chest pain of uncertain etiology evaluated using high-sensitivity T troponin, N-terminal pro-brain natriuretic peptide does not contribute additional predictive value to diagnosis or the prediction of short-term outcomes.

The HEART (History, Electrocardiogram, Age, Risk factors, and initial Troponin) score is an easy-to-apply instrument to stratify patients with chest pain according to their short-term risk for major adverse cardiac events (MACEs), but its effect on daily practice is unknown. To measure the effect of use of the HEART score on patient outcomes and use of health care resources. Stepped-wedge, cluster randomized trial. (ClinicalTrials.gov: NCT01756846). Emergency departments in 9 Dutch hospitals. Unselected patients with chest pain presenting at emergency departments in 2013 and 2014. All hospitals started with usual care. Every 6 weeks, 1 hospital was randomly assigned to switch to "HEART care," during which physicians calculated the HEART score to guide patient management. For safety, a noninferiority margin of a 3.0% absolute increase in MACEs within 6 weeks was set. Other outcomes included use of health care resources, quality of life, and cost-effectiveness. A total of 3648 patients were included (1827 receiving usual care and 1821 receiving HEART care). Six-week incidence of MACEs during HEART care was 1.3% lower than during usual care (upper limit of the 1-sided 95% CI, 2.1% [within the noninferiority margin of 3.0%]). In low-risk patients, incidence of MACEs was 2.0% (95% CI, 1.2% to 3.3%). No statistically significant differences in early discharge, readmissions, recurrent emergency department visits, outpatient visits, or visits to general practitioners were observed. Physicians were hesitant to refrain from admission and diagnostic tests in patients classified as low risk by the HEART score. Using the HEART score during initial assessment of patients with chest pain is safe, but the effect on health care resources is limited, possibly due to nonadherence to management recommendations.

A 58-year-old woman was referred to our cardiology service with chest pain, exertional dyspnoea and palpitations on a background of known Fabry disease diagnosed with genetic testing in 1994. ECG showed sinus rhythm, shortened PR interval, widespread t wave inversion, q waves in the lateral leads and left ventricular hypertrophy (LVH). Coronary angiogram showed only mild atheroma. Transthoracic echocardiogram showed anterolateral LVH and reduced left ventricular cavity size in keeping with Fabry cardiomyopathy. Cardiac MRI demonstrated asymmetric hypertrophy with evidence of diffuse myocardial fibrosis in the maximally hypertrophied segments from base to apex with late gadolinium enhancement in the anterior and anteroseptal walls. This was quite an atypical appearance for Fabry cardiomyopathy. This case highlights the heterogeneity of patterns of cardiac involvement that may be associated with this rare X-linked lysosomal disorder. 2016 BMJ Publishing Group Ltd.

Myocardial ischemia may alter the metal binding capacity of circulating serum albumin. Thus, the aim of this study was to describe an automated method to measure ischemia-induced alterations in the binding capacity of serum albumin for exogenous nickel, and to evaluate the diagnostic characteristics of this assay for the assessment of acute coronary syndrome (ACS) in patients presenting to the emergency room (ER) with acute chest pain. We assessed the concentrations of cardiac troponin I (cTnI), serum albumin, ischemia-modified albumin (IMA) measured by the cobalt-albumin binding assay (CABA), and by an automated nickel-albumin binding assay (NABA) in the following groups: ACS (n=63) and non-ischemic chest pain (NICP, n=26). Biochemical markers were determined in blood samples obtained from patients within 3 h of ER admission. cTnI, CABA and NABA concentrations were higher in ACS group in comparison to the NICP group. A significant correlation between NABA and CABA was observed (r=0.5387, p<0.001). Areas under the curve for CABA and NABA were 0.7289 and 0.7582, respectively. Both CABA and NABA have the ability to discriminate patients with ACS. However, NABA has a slightly higher ability to discriminate ACS compared with CABA. Patients with ACS have reduced nickel binding to human serum albumin, and NABA may have an important role as an early marker of myocardial ischemia, particularly in patients presenting to the ER with acute chest pain.

Background Chest CT scans are frequently performed in radiology departments but have not previously contained detailed depiction of cardiac structures. Objectives To evaluate myocardial and coronary visualization on high-pitch non-gated CT of the chest using 3rd generation dual-source computed tomography (CT). Methods Cardiac anatomy of patients who had 3rd generation, non-gated high pitch contrast enhanced chest CT and who also had prior conventional (low pitch) chest CT as part of a chest abdomen pelvis exam was evaluated. Cardiac image features were scored by reviewers blinded to diagnosis and pitch. Paired analysis was performed. Results 3862 coronary segments and 2220 cardiac structures were evaluated by two readers in 222 CT scans. Most patients (97.2%) had chest CT for oncologic evaluation. The median pitch was 2.34 (IQR 2.05, 2.65) in high pitch and 0.8 (IQR 0.8, 0.8) in low pitch scans (p<0.001). High pitch CT showed higher image visualization scores for all cardiovascular structures compared with conventional pitch scans (p<0.0001). Coronary arteries were visualized in 9 coronary segments per exam in high pitch scans versus 2 segments for conventional pitch (p<0.0001). Radiation exposure was lower in the high pitch group compared with the conventional pitch group (median CTDIvol 10.83 vs. 12.36 mGy and DLP 790 vs. 827 mGycm respectively, p <0.01 for both) with comparable image noise (p=0.43). Conclusion Myocardial structure and coronary arteries are frequently visualized on non-gated 3rd generation chest CT. These results raise the question of whether the heart and coronary arteries should be routinely interpreted on routine chest CT that is otherwise obtained for non-cardiac indications. PMID:27133589

Cardiorespiratory interactions and blood flow generation during cardiac arrest and other states of low blood flow.

Recent advances in cardiopulmonary resuscitation have shed light on the importance of cardiorespiratory interactions during shock and cardiac arrest. This review focuses on recently published studies that evaluate factors that determine preload during chest compression, methods that can augment preload, and the detrimental effects of hyperventilation and interrupting chest compressions. Refilling of the ventricles, so-called ventricular preload, is diminished during cardiovascular collapse and resuscitation from cardiac arrest. In light of the potential detrimental effects and challenges of large-volume fluid resuscitations, other methods have increasing importance. During cardiac arrest, active decompression of the chest and impedance of inspiratory airflow during the recoil of the chest work by increasing negative intrathoracic pressure and, hence, increase refilling of the ventricles and increase cardiac preload, with improvement in survival. Conversely, increased frequency of ventilation has detrimental effects on coronary perfusion pressure and survival rates in cardiac arrest and severe shock. Prolonged interruption of chest compressions for delivering single-rescuer ventilation or analyzing rhythm before shock delivery is associated with decreased survival rate. Cardiorespiratory interactions are of profound importance in states of cardiovascular collapse in which increased negative intrathoracic pressure during decompression of the chest has a favorable effect and increased intrathoracic pressure with ventilation has a detrimental effect on survival rate.

The History, Electrocardiography, Age, Risk factors, Troponin (HEART) score enables rapid risk stratification of emergency department patients presenting with chest pain. However, the subjectivity in scoring introduced by the history component has been criticized by some clinicians. We examined the association of 3 objective scoring models with the results of noninvasive cardiac testing. Medical records for all patients evaluated in the chest pain center of an academic medical center during a 1-year period were reviewed retrospectively. Each patient's history component score was calculated using 3 models developed by the authors. Differences in the distribution of HEART scores for each model, as well as their degree of agreement with one another, as well as the results of cardiac testing were analyzed. Seven hundred forty nine patients were studied, 58 of which had an abnormal stress test or computed tomography coronary angiography. The mean HEART scores for models 1, 2, and 3 were 2.97 (SD 1.17), 2.57 (SD 1.25), and 3.30 (SD 1.35), respectively, and were significantly different (P < 0.001). However, for each model, the likelihood of an abnormal cardiovascular test did not correlate with higher scores on the symptom component of the HEART score (P = 0.09, 0.41, and 0.86, respectively). While the objective scoring models produced different distributions of HEART scores, no model performed well with regards to identifying patients with abnormal advanced cardiac studies in this relatively low-risk cohort. Further studies in a broader cohort of patients, as well as comparison with the performance of subjective history scoring, is warranted before adoption of any of these objective models.

Despite a high prevalence of coronary heart disease in both genders, studies show a gender disparity in evaluation whereby women are less likely than men to undergo timely or comprehensive cardiac investigation. Using videographic analysis, we sought to quantify gender differences in provider recommendations and patient evaluations. We analyzed video recordings from our Chest Pain Choice trial, a single center patient-level randomized trial in which emergency department patients with chest pain being considered for cardiac stress testing were randomized to shared decision-making or usual care. Patient-provider interactions were video recorded. We compared characteristics and outcomes by gender. Of the 204 patients enrolled (101 decision aid; 103 usual care), 120 (58.8%) were female. Of the 75 providers evaluated, 20 (26.7%) were female. The mean (SD) pretest probability of acute coronary syndrome was lower in women [3.7% (2.2) vs 6.7% (4.4), P=.0002]. There was no gender effect on duration of discussion, clinician recommendations, OPTION scores, patient perceptions, or eventual patient dispositions. When the clinician and patient gender matched, OPTION scores were lower (interaction P=.002), and patients were less likely to find the information to be very helpful (interaction P=.10). Despite a lower pretest probability of acute coronary syndrome in women, we did not observe any significant gender disparity in how patients were managed and evaluated. When the patients' and providers' gender matched, the provider involved them less in the decision making process, and the information provided was less helpful than when the genders did not match.

Noncontrast cardiac computed tomography allows calculation of coronary artery calcium score (CACS) and measurement of epicardial adipose tissue (EATv) and intrathoracic fat (ITFv) volumes. It is unclear whether fat volume information contributes to risk stratification. Cardiac computed tomography was performed in 760 consecutive patients with acute chest pain admitted thorough the emergency department. None had prior coronary artery disease. CACS was calculated using the Agatston method. EATv and ITFv were semiautomatically calculated. Median patient follow-up was 3.3 years. Mean patient age was 54.4±13.7 years and Framingham risk score 8.2±8.2. The 45 patients (5.9%) with major acute cardiac events (MACE) were older (64.8±13.9 versus 53.7±13.4 years), more frequently male (60% versus 40%), and had a higher median Framingham risk score (16 versus 4) and CACS (268 versus 0) versus those without events (all P<0.01). The MACE group had a higher median of EATv (154 versus 116 mL) and ITFv (330 versus 223 mL), and a higher prevalence of EATv >125 mL (67% versus 44%) and ITFv >250 mL (64% versus 42%) (all P<0.01). CACS, EATv, and ITFv were all independently associated with MACE. CACS was associated with MACE after adjustment for fat volumes (P<0.0001), whereas EATv and ITFv improved the risk model only in patients with CACS >400. CACS and fat volumes are independently associated with MACE in acute chest pain patients and beyond that provided by clinical information alone. Although fat volumes may add prognostic value in patients with CACS >400, CACS is most strongly correlated with outcome.

Chest pain of gastrointestinal origin.

Twenty seven children who had been diagnosed as having idiopathic chest pain were investigated to find out if the pain was of gastrointestinal origin. The symptoms had lasted from two weeks to eight months. In 21 of the 27 children (78%) the chest pain had a gastrointestinal cause: 16 had oesophagitis, four had gastritis, and one had diffuse oesophageal spasm. All patients responded to medical treatment of their gastrointestinal symptoms, resulting in disappearance of the chest pain. PMID:3232993

To explore autogenic training (AT) as a treatment for psychological morbidity, symptomology, and physiological markers of stress among women with chest pain, a positive exercise test for myocardial ischemia, and normal coronary arteries (cardiac syndrome X). Fifty-three women with cardiac syndrome X (mean +/- SD age, 57.1 +/- 8 years) were randomized to an 8-week AT program or symptom diary control. Symptom severity and frequency, Hospital Anxiety and Depression Scale, Spielberger State-Trait Anxiety Inventory, Cardiac Anxiety Questionnaire (CAQ), and Ferrans and Powers Quality of Life Index (QLI), blood pressure, heart rate, electrocardiogram, and plasma catecholamines were measured before and after intervention and at the 8-week follow-up. Women who underwent AT had improved symptom frequency (8.04 +/- 10.08 vs 1.66 +/- 2.19, P < 0.001) compared with control women and reduced symtom severity (2.08 +/- 1.03 vs 1.23 +/- 1.36, P = 0.02) and frequency (6.11 +/- 3.17 vs 1.66 +/- 2.19, P < G 0.001) post-AT compared with baseline within group. Within-group improvements among women who underwent AT include QLI health functioning (17.80 +/- 5.74 vs 19.41 +/- 5.19, P = 0.04) and CAQ fear (1.53 +/- 0.61 vs 1.35 +/- 0.56, P = 0.02) post-AT and QLI health functioning (17.80 +/- 5.74 vs 20.09 +/- 5.47, P = 0.01), CAQ fear (1.53 +/- 0.61 vs 1.30 +/- 0.67, P = 0.002), CAQ total (1.42 +/- 0.54 vs 1.29 +/- 0.475, P = 0.04), Spielberger State-Trait Anxiety Inventory trait anxiety (42.95 +/- 11.19 vs 38.68 +/- 11.47, P = 0.01), and QLI quality of life (20.67 +/- 5.37 vs 21.9 +/- 4.89, P = 0.02) at follow-up. An 8-week AT program improves symptom frequency, with near-significant improvements in symptom severity in women with cardiac syndrome X.

This case report describes a patient who developed palpitations and chest pain and was found to be in atrial fibrillation, which was likely due to the presence of an extra-cardiac mass. This was compressing the left atrium. The mass was related to small cell carcinoma, which decreased significantly in size after chemotherapy. Resolution of the atrial fibrillation correlated temporally with reduction in the size of the mass and alleviation of the left atrial compression.

Silent myocardial ischemia is thought to be associated with worse cardiovascular outcomes due to a lack of perception of pain cues that initiate treatment seeking. Negative affect (NA) has been associated with increased pain reporting and positive affect (PA) with decreased pain reporting, but these psychological factors have not been examined within the context of myocardial ischemia. This study evaluated the associations between PA, NA, and chest pain reporting in patients with and without ischemia during exercise testing. A total of 246 patients referred for myocardial perfusion single-photon emission computed tomography exercise stress testing completed the positive and negative affect schedule-expanded version, a measure of PA and NA. Presence of chest pain and myocardial ischemia were evaluated using standardized protocols. Logistic regression analyses revealed that for every 1-point increase in NA, there was a 13% higher chance for ischemic patients (odds ratio [OR] = 1.13; 95% confidence interval [CI] = 1.02 to 1.26) and an 11% higher chance in nonischemic patients (OR = 1.11; 95% CI = 1.03 to 1.19) to report chest pain. A significant interaction of PA and NA on chest pain reporting (β = 0.02; 95% CI = 0.002 to 0.031) was also observed; nonischemic patients with high NA and PA reported more chest pain (57%) versus patients with low NA and low PA (13%), with high NA and low PA (17%), and with high PA and low NA (7%). Patients who experience higher NA are more likely to report experiencing chest pain. In patients without ischemia, high NA and PA was also associated with a higher likelihood of reporting chest pain. Results suggest that high levels of PA as well as NA may increase the experience and/or reporting of chest pain.

Chest pain is a common general practice presentation that requires careful diagnostic assessment because of its diverse and potentially serious causes. However, the evaluation of acute chest pain remains challenging, despite many new insights over the past two decades. The percentage of patients presenting to the emergency departments because of acute chest pain appears to be increasing. Nowadays, there are two essential chest pain-related issues: (i) the missed diagnoses of acute coronary syndromes with a poor short-term prognosis; and (ii) the increasing percentage of hospitalizations of low-risk cases. It is well known that hospitalization of a low-risk chest pain patient can lead to unnecessary tests and procedures, with an increasing trend of complications and burden of costs. Therefore, the significantly reduced financial resources of healthcare systems induce physicians and administrators to improve the efficiency of care protocols for patients with acute chest pain. Despite the efforts of the Scientific Societies in producing statements on this topic, in Italy there is still a significant difference between emergency physicians and cardiologists in managing patients with chest pain. For this reason, the aim of the present consensus document is double: first, to review the evidence-based efficacy and utility of various diagnostic tools, and, second, to delineate the critical pathways (describing key steps) that need to be implemented in order to standardize the management of chest pain patients, making a correct diagnosis and treatment as uniform as possible across the entire country.

Approximately 10-50% of chest pains are caused by musculoskeletal disorders. The association is twice as frequent in primary care as in emergency admissions. This article provides an overview of the most important musculoskeletal causes of chest pain and on the diagnostics and therapy. A selective search and analysis of the literature related to the topic of musculoskeletal causes of chest pain were carried out. Non-inflammatory diseases, such as costochondritis and fibromyalgia are frequent causes of chest pain. Inflammatory diseases, such as rheumatoid arthritis, spondyloarthritis and systemic lupus erythematosus are much less common but are more severe conditions and therefore have to be diagnosed and treated. The diagnostics and treatment often necessitate interdisciplinary approaches. Chest pain caused by musculoskeletal diseases always represents a diagnosis by exclusion of other severe diseases of the heart, lungs and stomach. Physiotherapeutic and physical treatment measures are particularly important, including manual therapy, transcutaneous electrical stimulation and stabilization exercises, especially for functional myofascial disorders.

The successive occurrence of pericardial tamponade and myocarditis during a Churg-Strauss syndrome is exceptionally described. We report a patient in whom pericardial tamponade and myocarditis were the presenting manifestation of a Churg-Strauss syndrome. A 58-year-old woman was admitted because of alteration of the clinical status with eosinophilia. One month ago, she was hospitalized for a pericardial tamponade treated by pericardial drainage. Acute myocarditis was diagnosed on chest pain during the second hospitalization. The etiologic inquiry ended in the diagnosis of Churg-Strauss complicated with a double cardiac involvement. A good response of clinical and biological anomalies was obtained after corticosteroid and immunosuppressive treatment. Isolated or multiple involvements of cardiac tunics should lead to make diagnosis of systemic vasculitis. A complete initial assessment and a close observation of the patients followed for Churg-Strauss syndrome is imperative to detect a cardiac achievement and set up an early treatment.

Patients presenting with chest pain in nonobstructive coronary artery disease (CAD, luminal narrowing <60%) are at risk for emotional distress and future events. We aimed to examine the association of personality subtypes with persistent chest pain, and investigated the potential mediating effects of negative mood states. Any chest pain in the past month was the primary outcome measure reported by 523 patients with nonobstructive CAD (mean age 61.4 years, SD = 9.4; 48% men), who participate in the TweeSteden Mild Stenosis (TWIST) observational cohort. Personality was categorized into a 'reference group', a high social inhibition ('SI only'), a high negative affectivity ('NA only') and a 'Type D' (NA and SI) group. Negative mood states included symptoms of depression and anxiety (Hospital Anxiety and Depression Scale) and cognitive and somatic depression (Beck Depression Inventory). The PROCESS macro was used to examine the relation between personality subtypes and chest pain presence, with the negative mood states as potential mediators. Persistent chest pain was present in 44% of the patients with nonobstructive CAD. Type D personality (OR = 1.91, 95% CI 1.24-2.95), but not the 'NA only' (OR = 1.48, 95% CI 0.89-2.44) or the 'SI only' (OR = 0.93, 95% CI 0.53-1.64) group was associated with chest pain, adjusted for age and sex. Negative mood states mediated the association between personality and chest pain. Type D personality, but not negative affectivity or social inhibition, was related to chest pain in nonobstructive CAD, which was mediated by negative mood states. © 2015 European Pain Federation - EFIC®

Discharge of Non-Acute Coronary Syndrome Chest Pain Patients From Emergency Care to an Advanced Nurse Practitioner-Led Chest Pain Clinic: A Cross-Sectional Study of Referral Source and Final Diagnosis.

PubMed

Ingram, Shirley J; McKee, Gabrielle; Quirke, Mary B; Kelly, Niamh; Moloney, Ashling

Chest pain is a common presentation to emergency departments (EDs). Pathways for patients with non-acute coronary syndrome (ACS) chest pain are not optimal. An advanced cardiology nurse-led chest pain service was commenced to address this. The aim of the study was to assess the outcomes of non-ACS patients discharged from ED to an advanced cardiology nurse-led chest pain clinic and compare by referral type (nurse or ED physician). The service consisted of advanced cardiology nurse or ED physician consultation in the ED and discharge to advanced nurse-led chest pain clinic review less than 72 hours after discharge. Referrals were by the advanced nurses during consult hours and out-of-hours were by the ED physicians. Data were extracted from case notes. This was a 1-site cross-sectional study of patients attending the chest pain clinic over 2 years. Confirmed coronary disease was diagnosed in 24% of patients. Of the 1041 patients, 45% were referred by the advanced nurses, who referred significantly more patients who were older (56.5 years/52.3 years), had positive exercise stress test results (21%/12%), and were diagnosed with stable coronary artery disease (19%/11%) and less patients with musculoskeletal diagnosis (5%/13%) and other noncardiac pain (36%/45%). The study fills a gap in the literature on the follow up of non-ACS patients who present to ED and used advanced cardiology nursing expertise in the ED and chest pain clinic. The advanced nurse referred more patients who were diagnosed with coronary disease, reflecting the expertise, experience, and efficiency of the advanced cardiology nurse-led service.

Cardiac trauma from penetrating chest injury is a life-threatening condition. It was reported that < 10% of patients arrives at the emergency department alive. Penetrating chest injury can cause serious damage in more than 1 cardiac structure, including myocardial lacerations, ventricular septal defect (VSD), fistula between aorta and right cardiac chamber and valves. The presence of pericardial effusion (even a small amount) on the initial echocardiography might be the only clue to serious cardiac damage in the absence of definite evidence of anatomical defect in heart. We here present a case, in which clear diagnosis of VSD and pseudoaneurysmal formation was delayed a few days after penetrating chest injury due to the lack of anatomical evidence of damage.

We report the case of a patient with pacemaker who presented chest pain during exercise followed by fainting. He has a history of arterial hypertension and diabetes. The initial examination was normal; the ventricular stimulation threshold was 1.125 volts (V) and cardiac enzymes were normal. Stress test has reproduced chest pain followed by loss of pacemaker capture and asystole. Coronary angiography showed a tight stenosis of the proximal anterior interventricular artery dilated by a drug-eluting stent. The control of stress test was normal. A stent thrombosis eight days later led to an acute coronary syndrome with recurrent syncope due to the loss of ventricular capture. The ventricular pacing threshold was then 2.25V. After revascularization and stabilization of the patient's clinical status, this threshold returned to 1.125V. This clinic case has confirmed that coronary artery disease could increase pacing threshold. It also highlights the usefulness of automatic capture algorithms in coronary patients. The stress test cannot only help to detect coronary artery disease but also allows the optimization of programming the pacemaker. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Takotsubo cardiomyopathy: an overlooked cause of chest pain

PubMed Central

Tomazelli, Bruno; Furieri, Natassia Prates; Coelho, Renato Alves; de Lima, Camila Fiorese

2014-01-01

Takotsubo cardiomyopathy (TTC), also known as apical ballooning syndrome, broken heart syndrome, or stress-induced cardiomyopathy, is defined as a transient disturbance of the left ventricle, which is quite often associated with electrocardiographic abnormalities that may mimic acute myocardial infarction. The syndrome is also characterized by a mild alteration of cardiac biomarkers in absence of coronary blood flow obstruction on the coronariography. Clinical presentation is often manifested by angina, dyspnea, syncope, and arrhythmias. Peculiarly, the left ventricle takes the form of “tako-tsubo” (a Japanese word for “octopus trap”) on the imaging workup. The authors report the case of a post-menopausal, hypertensive, dyslipidemic and type-II diabetic woman admitted at the emergency service with acute chest pain post physical exertion. Electrocardiogram showed signs of ischemia and myocardial necrosis markers were mildly increased. Echocardiography and ventriculography showed apical and mid-ventricular akinesia, with mild atherosclerotic coronary lesions. Thus diagnostic workup and the outcome followed the diagnostic criteria for TTC. The authors called attention to the potential of overlooking this diagnosis, since this syndrome is still not widely recognized. PMID:28580329

We report a rare case of spontaneous rupture of the ascending aorta without any evidence of aneurysm formation or aortic dissection. A woman aged 64 was admitted to our cardiac care unit as an emergency patient with severe chest pain. Her face was pale and systolic blood pressure was 70 mmHg in spite of intravenous administration of dopamine (10 micrograms/kg/min). She had a history of hypertension for two years under good medical control. No trace of the chest trauma was noted before her admission. Physical examination revealed neck vein engorgement and distant heart sounds. Chest X-ray film showed enlargement of the cardiac silhouette. ECG showed no evidence of acute coronary syndrome. Pericardial effusion with a floating hematoma-like mass was detected by 2-dimensional echocardiogram. Pericardiocentesis revealed bloody pericardial fluid (Ht: 26%). Aortagraphy was performed resulting in a clinical diagnosis of acute aortic dissection, but there were no signs of a false lumen, aneurysm formation or extravasation of the contrast medium. Although continuous pericardial drainage was performed, she suddenly lost consciousness, collapsed and died. A longitudinal intimal laceration 5 cm long was observed in the ascending aorta. Pathological examination revealed cystic medial necrosis and irregularity of the elastic fibers in the media. No atheromatous plaque was noted in the intima. Spontaneous rupture of the aorta is a life-threatening condition that requires urgent surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

Inferior Vena Cava Filter Limb Fracture with Embolization to the Right Ventricle.

Inferior vena cava (IVC) filter and filter limb embolization is a known phenomenon, with a prevalence of up to 25% for certain filter types. Most commonly, the site of embolization is to the heart. Point-of-care ultrasound is an easily accessible imaging modality that should be utilized when considering IVC filter complications. A 28-year-old woman with a history of metastatic sarcoma and IVC filter placement for deep venous thrombosis presented to the Emergency Department (ED) for chest pain. Chest radiography was reviewed and originally thought to have no abnormalities. Chest computed tomography angiography was negative for filling defects or foreign bodies. A possible foreign body in the heart was noted by a radiologist's over-read of the original chest radiograph. An echocardiogram done by Cardiology was negative for foreign bodies or other abnormalities. Next, an emergency physician performed a bedside echocardiogram, with focused attention to the right side of the heart. An echogenic foreign body was visualized in the right ventricle. The patient was subsequently taken to the cardiac catheterization laboratory, where fluoroscopic visualization of a limb wire of an IVC filter within the right ventricle was obtained. That foreign body was subsequently removed successfully, along with removal of the broken IVC filter. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case report highlights the utility of point-of-care ultrasound in the work-up of a patient with an embolized IVC filter wire. Chest pain patients frequently receive point-of-care echocardiography in the ED, and these ultrasound findings should be recognized and used to guide further treatment and consultation.

The recognition of coronary artery disease (CAD) among patients who report chest pain remains difficult in primary care. This study investigates the association between chest pain (specified, unspecified or musculoskeletal) and prodromes (dyspepsia, fatigue or dyspnoea), with first-ever acute CAD, and increased longer term cardiovascular risk. Cohort study. Anonymised clinical data recorded electronically by general practitioners from 140 primary care surgeries in London (UK) between April 2008 and April 2013. Data were extracted for all patients aged 30 years and over at the beginning of the study period, registered in the surgeries. Clinical data included chest pain, dyspepsia, dyspnoea and fatigue, first-ever CAD and long-term cardiovascular risk (QRisk2). Regression models were used to analyse the association between chest pain together with prodromes and CAD and QRisk2≥20%. 354,052 patients were included in the study. 4842 patients had first-ever CAD of which 270 reported chest pain in the year before the acute event. 257,019 patients had QRisk2 estimations. Chest pain was associated with a higher risk of CAD. HRs: 21.12 (16.68 to 26.76), p<0.001; 7.51 (6.49 to 8.68), p<0.001; and 1.84 (1.14 to 3.00), p<0.001 for specified, unspecified and musculoskeletal chest pain. Dyspepsia, dyspnoea or fatigue was also associated with a higher risk of CAD. Chest pain of all subtypes, dyspepsia and dyspnoea were also associated with an increased 10-year cardiovascular risk of 20% or more. All patients with chest pain, including those with atypical symptoms, require careful assessment for acute and longer term cardiovascular risk. Prodromes may have independent diagnostic value in the estimation of cardiovascular disease risk. Published by the BMJ Publishing Group Limited.

Cardiac involvement in immunoglobulin light chain (amyloid light chain, AL) amyloidosis is characterized by myocardial interstitial deposition but can also cause obstructive deposits in the coronary microvasculature. We retrospectively identified 20 patients who underwent stress echocardiography within 1 year prior to the histologic diagnosis of AL amyloidosis. Only patients with cardiac amyloidosis and no known obstructive coronary disease were included. Stress echocardiograms (13 exercise; 7 dobutamine) were performed for evaluation of dyspnea and/or chest pain. Stress-induced wall motion abnormalities (WMAs) occurred in 11 patients (55%), 4 of whom had normal left ventricular wall thickness. Coronary angiogram was performed in 9 of 11 patients and demonstrated no or mild epicardial coronary artery disease. Seven (54%) patients had an abnormal exercise blood pressure which occurred with similar likelihood between those with and without stress-induced WMAs. Stress-induced WMAs and abnormal exercise blood pressure may occur in patients with cardiac AL amyloidosis despite the absence of significant epicardial coronary artery disease. This finding should raise the possibility of cardiac amyloidosis even in the absence of significant myocardial thickening.

2004-01-01

The McGill Pain Questionnaire (MPQ) provides a quantitative profile of 3 major psychologic dimensions of pain: sensory-discriminative, motivational-affective, and cognitive-evaluative. Although the MPQ is frequently used as a pain measurement tool, no studies to date have compared the characteristics of chronic post-surgical pain after different surgical procedures using a quantitative scoring method. Three separate questionnaire surveys were administered to patients who had undergone surgery at different time points between 1990 and 2000. Surgical procedures selected were mastectomy (n = 511 patients), inguinal hernia repair (n = 351 patients), and cardiac surgery via a central chest wound with or without saphenous vein harvesting (n = 1348 patients). A standard questionnaire format with the MPQ was used for each survey. The IASP definition of chronic pain, continuously or intermittently for longer than 3 months, was used with other criteria for pain location. The type of chronic pain was compared between the surgical populations using 3 different analytical methods: the Pain Rating Intensity score using scale values, (PRI-S); the Pain Rating Intensity using weighted rank values multiplied by scale value (PRI-R); and number of words chosen (NWC). The prevalence of chronic pain after mastectomy, inguinal herniorrhaphy, and median sternotomy with or without saphenectomy was 43%, 30%, and 39% respectively. Chronic pain most frequently reported was sensory-discriminative in quality with similar proportions across different surgical sites. Average PRI-S values after mastectomy, hernia repair, sternotomy (without postoperative anginal symptoms), and saphenectomy were 14.06, 13.00, 12.03, and 8.06 respectively. Analysis was conducted on cardiac patients who reported anginal symptoms with chronic post-surgical pain (PRI-S value 14.28). Patients with moderate and severe pain were more likely to choose more than 10 pain descriptors, regardless of the operative site (P < 0.05). The prevalence and characteristics of chronic pain was remarkably similar across different operative groups. This study is the first to quantitatively compare chronic post-surgical pain using similar methodologies in heterogeneous post-surgical populations.

Purpose: Stereotactic body radiation therapy (SBRT) is increasingly being used to treat thoracic tumors. We attempted here to identify dose-volume parameters that predict chest wall toxicity (pain and skin reactions) in patients receiving thoracic SBRT. Patients and Methods: We screened a database of patients treated with SBRT between August 2004 and August 2008 to find patients with pulmonary tumors within 2.5 cm of the chest wall. All patients received a total dose of 50 Gy in four daily 12.5-Gy fractions. Toxicity was scored according to the NCI-CTCAE V3.0. Results: Of 360 patients in the database, 265 (268 tumors) had tumorsmore » within <2.5 cm of the chest wall; 104 (39%) developed skin toxicity (any grade); 14 (5%) developed acute pain (any grade), and 45 (17%) developed chronic pain (Grade 1 in 22 cases [49%] and Grade 2 or 3 in 23 cases [51%]). Both skin toxicity and chest wall pain were associated with the V{sub 30}, or volume of the chest wall receiving 30 Gy. Body mass index (BMI) was also strongly associated with the development of chest pain: patients with BMI {>=}29 had almost twice the risk of chronic pain (p = 0.03). Among patients with BMI >29, diabetes mellitus was a significant contributing factor to the development of chest pain. Conclusion: Safe use of SBRT with 50 Gy in four fractions for lesions close to the chest wall requires consideration of the chest wall volume receiving 30 Gy and the patient's BMI and diabetic state.« less

[The theory of cardiac lesions from blunt chest injury].

PubMed

Tumanov, E V; Sokolova, Z Iu

2010-01-01

The main theories of myocardial lesions associated with a blunt chest injury proposed starting from the XIXth century till the present time are considered based on the overview of the literature data. It is shown that the theory of selective mechanical activation of ATP-dependent K+ channels is most promising for further investigations into the mechanisms of myocardial dysfunction resulting from blunt chest injuries. The authors emphasize the absence of the universally accepted theory explaining the mechanism behind traumatic cardiac troubles and its fatal outcome despite numerous studies of cardiac lesions in patients with a blunt chest injury. It dictates the necessity of further research, both clinical and experimental, for a deeper insight into the problem.

Cardiac output increases prior to development of pulmonary edema after re-expansion of spontaneous pneumothorax.

Pulmonary edema following reexpansion of spontaneous pneumothorax is an uncommon complication. The underlying mechanism of this condition is unclear. We report the hemodynamic characteristics in a series of 7 male patients with spontaneous large (>50%) pneumothoraces of > or = 24 h and correlate the changes with reexpansion pulmonary edema (REPE). A pulmonary artery floatation catheter was inserted and hemodynamic data were obtained before therapeutic chest tube insertion, 1 h after chest tube insertion and the following day. Four (57%) patients developed REPE. There was a tendency for larger pneumothorax to develop REPE. Capillary wedge pressure did not change significantly 1 h after the insertion of chest tube in all our patients. Cardiac output increased significantly in patients who developed REPE compared to those who did not (+ 1.06 l/min vs -0.27 l/min; P = 0.03) 1 h after insertion of chest tube. One patient did not develop pulmonary edema despite having a large (> 80%) pneumothorax. His cardiac output did not rise 1 h after chest tube insertion. REPE is not an uncommon complication following chest tube drainage in patients with large and long-standing pneumothorax. The increase in cardiac output after chest tube insertion may be associated with subsequent development of REPE.

A healthy scuba diver presented with a NSTEMI (non-ST segment elevation myocardial infarction), pneumothorax and pneumomediastinum after diving. A 34-year-old woman with no significant medical history presented to the emergency department after an episode of loss of consciousness and seizure-like activity after an uncontrolled ascent during a dive in a freshwater lake at 5,700 feet of altitude. A chest radiograph showed pneumothorax, pneumomediastinum and pneumopericardium. She had septal infarction as indicated by ECG, and elevated troponin. Echocardiogram revealed a mildly depressed left ventricular ejection fraction (LVEF) with apical akinesis. Coronary angiogram showed normal coronary arteries. Hyperbaric oxygen was not given since evaluation occurred 28 hours after the event: The patient had a pneumothorax, and was neurologically normal. She was discharged on angiotensin-converting enzyme inhibitors (ACE-I) and opioids for chest pain. Cardiac function normalized on transthoracic echocardiogram (TTE) two weeks later, but she continued to complain of chest pain that was treated with dihydropyridine calcium channel blockers. She then developed pericarditis confirmed by CMRI, requiring treatment with non-steroidal anti-inflammatory drugs (NSAIDS), colchicine and steroids. Five months after the accident, she was asymptomatic, with excellent exercise function and normal exercise stress echocardiogram. Reports of myocardial injury caused by arterial gas embolism from diving are rare. This case shows coronary air embolism complicating pulmonary barotrauma and may be the first report of pericarditis complicating myocardial injury after an AGE.

Witnesses of a sudden cardiac arrest play a key-role in resuscitation. Lay-persons should therefore be trained to recognize that a collapsed person who is not breathing at all or breathing normally might suffer from cardiac arrest. Information of professional emergency medical staff by lay-persons and their initiation of cardio-pulmonary-resuscitation-measures are of great importance for cardiac-arrest victims. Ambulance-dispatchers have to support lay-rescuers via telephone. This support includes the localisation of the nearest Automatic External Defibrillator (AED). Presentation of agonal breathing or convulsions due to brain-hypoxia need to be recognized as potential early signs of cardiac arrest. In any case of cardiac arrest chest-compressions need to be started. There is insufficiant data to recommend "chest-compression-only"-CPR as being equally sufficient as cardio-pulmonary-resuscitation including ventilation. Rescuers trained in ventilation should therefore combine compressions and ventilations at a 30:2-ratio. Movement of the chest is being used as a sign of sufficient ventilation. High-quality chest-compressions of at least 5 cm of depth, not exceeding 6 cm, are recommended at a ratio of 100-120 chest conpressions/min. Interruption of chest-compression should be avoided. At busy public places AED should be available to enable lay-rescuers to apply early defibrillation. © Georg Thieme Verlag Stuttgart · New York.

Blunt impact to the chest leading to sudden death from cardiac arrest during sports activities.

Sudden death from cardiac arrest in a young person may occur during sports play after a blunt blow to the chest in the absence of structural cardiovascular disease or traumatic injury (cardiac concussion or commotio cordis). We studied the clinical features of this apparently uncommon but important phenomenon. We identified cases from the registries of relevant agencies and organizations, as well as newsmedia accounts, and developed a clinical profile of 25 children and young adults, 3 to 19 years of age. Each victim collapsed with cardiac arrest immediately after an unexpected blow to the chest, which was usually inflicted by a projectile (such as a baseball or hockey puck). Incidents took place during organized competitive sports in 16 cases and in recreational settings at home, at school, or on the playground in 9. In each instance, the impact to the chest was not judged to be extraordinary for the sport involved and did not appear to have sufficient force to cause death. Twelve victims collapsed virtually instantaneously on impact, whereas 13 remained conscious and physically active for a brief time before cardiac arrest. Cardiopulmonary resuscitation was administered within about three minutes to 19 victims, but normal cardiac rhythm could be restored in only 2 (both incurred irreversible brain damage and died shortly thereafter). Seven victims (28 percent) were wearing some form of protective chest padding. We speculate that most sudden deaths related to impact to the chest (not associated with traumatic injury) are due to ventricular dysrhythmia induced by an abrupt, blunt precordial blow, presumably delivered at an electrically vulnerable phase of ventricular excitability. This profile of blunt chest impact leading to cardiac arrest adds to our understanding of the range of causes of sudden death on the athletic field and may help in the development of preventive measures.

Tilmicosin phosphate is a macrolide antibiotic that is used to treat cattle for pathogens that cause Bovine Respiratory Disease. A 28-year-old man with no prior history of heart disease developed severe chest pain, inverted T waves, and intraventricular conduction delay on EKG and mild elevation of cardiac enzymes 5 hours after unintentional injection of less than half of a 12cc syringe filled with Micotil 300 (tilmicosin phosphate 300 mg/mL, propylene glycol 25%, phosphoric acid, water for injection). The patient made an uneventful recovery after hospitalization. This case provides evidence that unintentional injection of tilmicosin can cause cardiac symptoms and laboratory evidence of myocardial injury. Tilmicosin should always be administered by properly trained personnel who are using techniques designed to reduce the risk of accidental self-injection.

Bard Denali inferior vena cava filter fracture and embolization resulting in cardiac tamponade: a device failure analysis.

PubMed

Kuo, William T; Robertson, Scott W

2015-01-01

A 46-year-old woman underwent inferior vena cava filter placement before bariatric surgery and returned within 6 months for routine removal. She complained of a 1-week history of severe chest pain, and during retrieval, two fractured filter components were identified including one arm in the right ventricle. The filter body and one fragment were successfully retrieved, but the fragment in the right ventricle was refractory to percutaneous retrieval. During open-heart surgery, the fragment was found traversing through the ventricular wall resulting in cardiac tamponade. Electron microscopic fragment analysis revealed high-cycle metal fatigue indicating the filter design failed to withstand this patient's natural inferior vena cava biomechanical motions.

Non-cardiac chest pain: the long-term natural history and comparison with gastroesophageal reflux disease.

PubMed

Williams, Jonathan F; Sontag, Stephen J; Schnell, Thomas; Leya, Jack

2009-09-01

The source of most cases of non-cardiac chest pain (NCCP) is thought to be the esophagus. We reasoned that if the origin of NCCP is truly esophageal and not cardiac, the characteristics and survival of individuals with NCCP should be similar to those of individuals with benign esophageal disease, such as gastroesophageal reflux disease (GERD). The aim of this study was to compare the characteristics, natural history, and long-term survival of two well-defined groups, NCCP patients and GERD patients. From 1984 to 1996, patients with NCCP were referred for endoscopy by the cardiology service after a coronary angiography done for chest pain was reported by the cardiologist as negative. Patients with GERD were referred for endoscopy for one of the usual symptoms of acid reflux. The baseline endoscopy and referrals occurred in the pre-proton pump inhibitor (PPI) era, before and during the availability of only the histamine receptor antagonists (HRAs). Thus, the endoscopic findings reflected the untreated natural state of the gastrointestinal mucosa. Endoscopic exams, esophageal biopsy, endoscopic anatomy mapping, and data verification were carried out in the endoscopy lab by one of three endoscopists using predefined criteria. All results were recorded both by hand and by entry into a database storage program. Patients were followed by their primary care providers in their usual outpatient general medicine clinics. The Veterans Affairs Decentralized Hospital Computer Program (VA DHCP) storage system provided access to mortality data as well as details of all prescriptions filled since 1985. During the 12-year enrollment period, 1,218 patients in the GERD group and 161 in the NCCP group were referred for endoscopy. The follow-up period ranged from 1-22 years (mean 9.8 years). The groups were similar in age, gender, smoking and alcohol habits, and use of aspirin and NSAIDs (non-steroidal anti-inflammatory drugs) (P=NS), but there was a greater proportion of blacks in the NCCP group (P<0.003). In every parameter, NCCP patients had a significantly lower prevalence of GERD-related findings such as endoscopic esophagitis (P<0.0001), Barrett's metaplasia (P=0.02), the development of esophageal adenocarcinoma, and hiatal hernia presence (P=0.0001). In patients with hiatal hernia, the size of the hernia was similar in both groups (P=0.94). In the NCCP group compared with the GERD group, there was a significantly higher prevalence of cardiac factors, such as coronary artery disease (P=0.03), and there was a trend toward greater cardiac clinic enrollment (P=0.08) and cardiac medication usage (P=0.06). The amount and duration of anti-GERD therapy, such as HRAs and PPIs, were significantly less in the NCCP group (P=0.0001 for PPIs and P=0.0002 for HRAs). The diagnosis of NCCP disappeared from the electronic hospital record in 96% of patients within 2 years of follow-up. There was no significant difference in survival between the GERD and NCCP groups (hazard ratio=1.1; CI=0.8-1.5); however, longer duration of follow-up in those with a greater number of events may make a difference in survival. NCCP in most patients seems to be a short-lived event requiring extensive medical evaluation and having clinical characteristics significantly different from those associated with GERD. Patients with NCCP, confirmed by the absence of angiogram-documented coronary artery disease, who are referred for diagnostic endoscopy, have an excellent long-term benign prognosis, similar to patients with GERD.

Cardiovascular disease is a major cause of death in Iran. With regard to the socio-economic status, a low educational level is associated with a higher frequency of disease. The aim of this study was to investigate, in a developing country, the influence of educational level and gender on the prevalence of coronary artery disease and cardiovascular risk factors in patients with chest pain at the time of admission and after 3 months of follow-up. We studied 240 consecutive patients (113 males, 127 females, age 16-97 years) who presented with chest pain believed to be of cardiac origin. The patients were admitted to a metropolitan hospital in Teheran from September 8, 2001 to December 8, 2001. Males were found to have a higher educational level than females (p = 0.0001). Females more frequently had a history of hypertension (44.9 vs 23%, p = 0.0001) and of diabetes mellitus (24.4 vs 11.5%, p = 0.01) and presented with more electrocardiographic abnormalities (37.0 vs 27.4%, p = 0.033) than males. Furthermore, patients with a low educational level were less likely to be on beta-blockers (23.9 vs 53.3%, p = 0.000), nitrates (20.2 vs 42.2%, p = 0.002) and acetylsalicylic acid (22.4 vs 50%, p = 0.000) compared to patients with a high educational level. Males were more often transported by ambulance to the hospital than females (p = 0.001). There was a high prevalence of risk factors for ischemic heart disease (cigarette smoking, diabetes mellitus, hypertension and dyslipidemia) (65% had one or more risk factors) with no relation to educational level. We found a high prevalence of risk factors for coronary artery disease in an Iranian population admitted with chest pain. In particular less educated women were at an increased risk and had more electrocardiographic abnormalities. Our findings stress the importance of the socio-economic status in cardiovascular disease and of the need for health promotion and lifestyle changes.

Update on mechanical cardiopulmonary resuscitation devices.

2016-06-01

The aim of this review is to update and discuss the use of mechanical chest compression devices in treatment of cardiac arrest. Three recently published large multicenter randomized trials have not been able to show any improved outcome in adult out-of-hospital cardiac arrest patients when compared with manual chest compressions. Mechanical chest compression devices have been developed to better deliver uninterrupted chest compressions of good quality. Prospective large randomized studies have not been able to prove a better outcome compared to manual chest compressions; however, latest guidelines support their use when high-quality manual chest compressions cannot be delivered. Mechanical chest compressions can also be preferred during transportation, in the cath-lab and as a bridge to more invasive support like extracorporeal membrane oxygenation.

Purpose: The purpose of this analysis was to evaluate dose-volume relationships associated with a higher probability for developing chest wall toxicity (pain) after accelerated partial breast irradiation (APBI) by using both single-lumen and multilumen brachytherapy. Methods and Materials: Rib dose data were available for 89 patients treated with APBI and were correlated with the development of chest wall/rib pain at any point after treatment. Ribs were contoured on computed tomography planning scans, and rib dose-volume histograms (DVH) along with histograms for other structures were constructed. Rib DVH data for all patients were sampled at all volumes {>=}0.008 cubic centimeter (cc)more » (for maximum dose related to pain) and at volumes of 0.5, 1, 2, and 3 cc for analysis. Rib pain was evaluated at each follow-up visit. Patient responses were marked as yes or no. No attempt was made to grade responses. Eighty-nine responses were available for this analysis. Results: Nineteen patients (21.3%) complained of transient chest wall/rib pain at any point in follow-up. Analysis showed a direct correlation between total dose received and volume of rib irradiated with the probability of developing rib/chest wall pain at any point after follow-up. The median maximum dose at volumes {>=}0.008 cc of rib in patients who experienced chest wall pain was 132% of the prescribed dose versus 95% of the prescribed dose in those patients who did not experience pain (p = 0.0035). Conclusions: Although the incidence of chest wall/rib pain is quite low with APBI brachytherapy, attempts should be made to keep the volume of rib irradiated at a minimum and the maximum dose received by the chest wall as low as reasonably achievable.« less

Determination of cardiac size from chest roentgenograms following Skylab missions

1974-01-01

Decreased cardiothoracic transverse diameter ratios following Mercury, Gemini and Apollo space flights have been reported previously. To evaluate further changes in cardiac size, standard posteroanterior chest films in systole and diastole were obtained before flight and within a few hours after recovery on each of the Skylab astronauts. Postflight chest X-rays were visually compared to the preflight roentgenograms for possible changes in pulmonary vasculature, lung parenchyma, bony or soft tissue structures. From these roentgenograms the following measurements were obtained: cardiac and thoracic transverse diameters, cardiothoracic transverse diameter ratio, cardiac area from the product of both diagonal diameters, cardiac silhouette area by planimetry, thoracic cage area and cardiothoracic area ratio. The postflight frontal cardiac silhouette sizes were significantly decreased when compared with the respective preflight values (P0.05 or 0.01). The observed changes are thought to be related to postflight decrease in the intracardiac chamber volume.

Depression masquerading as chest pain in a patient with Wolff Parkinson White syndrome

2016-01-01

Wolff Parkinson White (WPW) syndrome is a condition in which there is an aberrant conduction pathway between the atria and ventricles, resulting in tachycardia. A 42-year-old patient, who was treated for WPW syndrome previously, presented with chronic somatic pain. With her cardiac condition in mind, she was thoroughly worked up for a recurrence of disease. As part of routine screening of all patients at our pain clinic, she was found to have severe depression as per the Patient Health Questionnaire–9 (PHQ–9) criteria. After ruling out sinister causes, she was treated for depression using oral Duloxetine and counselling. This led to resolution of symptoms, and improved her mood and functional capability. This case highlights the use of psychological screening tools and diligent examination in scenarios as confusing as the one presented here. Addressing the psychological aspects of pain and adopting a holistic approach are as important as treatment of the primary pathology. PMID:27738505

Response of unexplained chest pain to proton pump inhibitor treatment in patients with and without objective evidence of gastro-oesophageal reflux disease.

Kahrilas, Peter J; Hughes, Nesta; Howden, Colin W

2011-11-01

Unexplained chest pain is potentially attributable to gastro-oesophageal reflux disease (GORD) or oesophageal motility disorders. Reflux chest pain may occur without heartburn. We explored the response of unexplained chest pain to proton pump inhibitor (PPI) therapy in randomised clinical trials (RCTs), differentiating patients with and without objective evidence of GORD. PubMed and Embase were systematically searched for RCTs that reported chest pain response to PPIs in patients who had had pH-monitoring and/or endoscopy to differentiate GORD-positive from GORD-negative subpopulations. Heterogeneity among studies was assessed using the Cochran Q and I(2) statistics, and a fixed effect model was applied. Possible publication bias was assessed by Egger's test. Six RCTs met the inclusion criteria. All used 24 h pH monitoring and/or endoscopy to define GORD-positive patients and improvement in chest pain to define response (five used ≥50%; one used ≥ 20%). The therapeutic gain of >50% improvement with PPIs relative to placebo was 56-85% in GORD-positive and 0-17% in GORD-negative patients. The RR of >50% improvement in chest pain with PPI versus placebo was 4.3 (95% CI 2.8 to 6.7; p<0.0001) for GORD-positive and 0.4 (95% CI 0.3 to 0.7; p=0.0004) for GORD-negative patients. Concomitant heartburn varied among trials from being an exclusion criterion to being essentially concordant with GORD-positive status. Unexplained chest pain in patients with endoscopic or pH-monitoring evidence of GORD tends to improve, but not resolve, with PPI therapy, whereas GORD-negative patients have little or no response. Heartburn was a poor predictor of whether patients with chest pain were GORD-positive or GORD-negative by objective testing.

High-resolution esophageal manometry (HREM) has become a leading tool in the assessment of esophageal motor disorders, replacing conventional manometry. However, there is limited data about the contribution of HREM as compared with conventional manometry to the assessment of esophageal motor disorders in patients with non-cardiac chest pain (NCCP). The aim of the study was to compare the distribution of esophageal motor disorders in patients with NCCP using HREM as compared with conventional manometry and to determine if HREM improved diagnosis of these disorders. In this study, we included 300 consecutive patients with NCCP who underwent either HREM or conventional manometry over a period of 10 years. A total of 150 patients had conventional manometry and the other 150 patients HREM. The Chicago 3.0 classification and the Castell and Spechler classification were used to determine the esophageal motor disorder of NCCP patients undergoing HREM and conventional manometry, respectively. In both HREM and the conventional manometry groups, normal esophageal motility was the most frequent finding (47% and 36%; respectively, P = .054). Hypotensive lower esophageal sphincter was the most common motility disorder identified by conventional manometry (27.3%), while ineffective esophageal motility was the most common esophageal motor disorder identified by HREM (25.3%). There is a discrepancy in the type of esophageal motor disorders identified by HREM as compared with conventional manometry in NCCP patients. Hypotensive motility disorders are the most commonly diagnosed by both manometric techniques. © 2017 John Wiley & Sons Ltd.

Nutcracker esophagus and non-specific motility disorders are the main causes of non-cardiac chest pain (NCCP), with gastroesophageal reflux in 60% of cases. Achalasia and diffuse esophageal spasm are the most frequent anomalies described in patients with dysphagia. The goal of this study was to evaluate the occurrence of esophageal body and lower esophageal sphincter motor abnormalities in patients with dysphagia, NCCP, or both. This study is a retrospective analysis of 716 patients with NCCP and/or dysphagia tested between January 1994 and December 2010. 1023 functional studies were performed, 707 of which were esophageal manometries, 225 esophageal pH-meters, and 44 bilimetries. We divided the patients into three groups: group 1 was composed of patients affected with dysphagia, group 2 with NCCP and group 3 with NCCP and dysphagia. Manometric anomalies were detected in 84.4% of cases (p<0.001). The most frequent esophageal motility alteration was achalasia (36%). The lower esophageal sphincter was normal in 45.9% of patients (p<0.001). In all 3 groups, 80.9%, 98.8%, and 93.8, respectively, of patients showed normal upper esophageal sphincter (p=0.005). Our data differs from those of other studies because they were collected from and analyzed by a single tertiary level referral center by a single examiner. This could have eliminated the variability found in different hands and different experiences. The high percentage of symptomatic patients with non-pathologic esophageal motility pattern suggests an unclear origin of the disease, with possible neuromuscular involvement. As a result, these patients may need more-detailed diagnostic studies.

Patients with functional esophageal disorders represent a challenging treatment group. The purpose of this study was to evaluate the role of biofeedback in the treatment of patients with functional esophageal disorders. In this prospective study, patients with typical/atypical symptoms of gastroesophageal reflux disease underwent upper endoscopy and 24-h pH monitoring. All patients filled out gastroesophageal Reflux Disease Symptom, Hospital Anxiety and Depression, and Symptom Stress Rating questionnaires. Patients with functional heartburn and those with functional chest pain were offered biofeedback treatment. A global assessment questionnaire was filled out at the end of treatment and then 2.8 (range 1-4) years later. From January 2006 to December 2009, 22 patients with functional esophageal diseases were included in the study. Thirteen had functional heartburn and nine had functional chest pain. Six patients from each group received biofeedback treatment. After treatment for 1-4 years, patients with functional chest pain showed significant improvements in symptoms compared with those who were not treated. Patients with functional heartburn showed no improvement. Patients with functional chest pain had a longer time of esophageal acid exposure than those with functional heartburn. Patients with functional chest pain have different central and intraesophageal factors associated with symptom generation in comparison with patients with functional heartburn. Biofeedback is a useful tool in the treatment of patients with functional chest pain, but not for those with functional heartburn.

We report 5 cases of spontaneous pneumomediastinum. They were 4 men and 1 female with a mean age of 17 (14-25). Four patients developed sport-related pneumomediastinum and 1 patient had a karaoke-related condition. Primary spontaneous pneumomediasinum is a rare condition. In addition, there is no previous report describing karaoke-related spontaneous pneumomediastinum. Each of the patients experienced chest pain and/or neck pain before consulting our hospital. Chest roentgenogram and chest computed tomography showed pneumomediastinum without esophageal or tracheal injury. Four patients did not require hospitalization, but 1 patient was necessary to hospitalize for 7 days because of severe chest and neck pain. None of these 5 patients has had any recurrence for more than 1 year. Differentiating this entity from other diseases involving anterior chest pain is important.

Acute coronary syndrome remains a dominant cause of high morbidity and mortality despite advancements in treatment This study was conducted to examine the utility of point-of-care test of heart-type fatty-acid binding protein (h-FABP) and compare it with the point-of-care test of cardiac troponin I (cTnI) in the first 06 hours of STEMI. This cross-sectional, comparative study which was conducted in Rawalpindi institute of cardiology, Rawalpindi, Pakistan, from January to June 2015. Serum samples of 125 patients with the diagnosis of STEMI, presenting with chest pain of less than 6 hours' duration, were analysed for quantitative and qualitative determination of h-FABP and cardiac troponin I (cTnI) using rapid immunochromatographic technique in the emergency department. Samples were taken at presentation and after 12 hours. Out of 125 patients, 112 were males and 13 were females with a mean age of 54.26±9.53 years. The average symptom-to-sample time was 3.19±1.44 hours (median 3 hours). Mean h-FABP levels were significantly higher than the mean cTnI levels (29.10±30.66 vs 0.94±2.02; p=0.000). Overall, HFABP was more sensitive than cTnI (72% vs 26.4%). The sensitivity of cTnI within 0-2, 2-4, and 4-6 hours of symptom onset was calculated to be 0%, 17.7%, and 75.9%, whereas sensitivity of HFABP was 35.3%, 79.03% and 100% respectively. There was not a single patient who was cTnI positive and H-FABP negative as compared to 57 patients who were FABP positive and cTnI negative. h-FABP is a promising cardiac biomarker for the early identification of myocardial ischemia and infarction. It could be a superior biomarker for earlier detection of ACS and screening of patients with non-cardiac chest pain.

Abstract Objective. To evaluate the safety and cost-effectiveness of point-of-care troponin T testing (POCT-TnT) for the management of patients with chest pain in primary care. Design. Prospective observational study with follow-up. Setting. Three primary health care (PHC) centres using POCT-TnT and four PHC centres not using POCT-TnT in south-east Sweden. Patients. All patients ≥ 35 years of age, contacting one of the PHC centres for chest pain, dyspnoea on exertion, unexplained weakness and/or fatigue, with no other probable cause than cardiac, were included. Symptoms must have commenced or worsened during the previous seven days. Main outcome measures. Emergency referral rates, diagnoses of acute myocardial infarction (AMI) or unstable angina (UA), and costs were collected for 30 days after the patient sought care at the PHC centre. Results. A total of 196 patients with chest pain were included: 128 in PHC centres with POCT-TnT and 68 in PHC centres without POCT-TnT. Fewer patients from the PHC centres with POCT-TnT (n = 32, 25%) were emergently referred to hospital than from centres without POCT-TnT (n = 29, 43%; p = 0.011). Eight patients (6.2%) from PHC centres with POCT-TnT were diagnosed with AMI or UA compared with six patients (8.8%) from centres without POCT-TnT (p = 0.565). Two patients with AMI or UA were classified as missed cases from PHC centres with POCT-TnT and there were no missed cases from PHC centres without POCT-TnT. SKr290 000 was saved per missed case of AMI or UA. Conclusion. The use of POCT-TnT in primary care may be cost saving but at the expense of missed cases. PMID:25434410

Regional Pericarditis Status Post Cardiac Ablation: A Case Report

Context: Regional pericarditis is elusive and difficult to diagnosis. Healthcare providers should be familiar with post-cardiac ablation complications as this procedure is now widespread and frequently performed. The management of regional pericarditis differs greatly from that of acute myocardial infarction. Case report: A 52 year-old male underwent atrial fibrillation ablation and developed severe mid-sternal chest pain the following day with electrocardiographic findings suggestive of acute myocardial infarction, and underwent coronary angiography, a left ventriculogram, and 2D transthoracic echocardiogram, all of which were unremarkable without evidence of obstructive coronary disease, wall motion abnormalities, or pericardial effusions. Ultimately, the patient was diagnosed with regional pericarditis. After diagnosis, the patient's presenting symptoms resolved with treatment including nonsteroidal anti-inflammatory agents and colchicine. Conclusion: This is the first reported case study of regional pericarditis status post cardiac ablation. Electrocardiographic findings were classic for an acute myocardial infarction; however, coronary angiography and left ventriculogram demonstrated no acute coronary occlusion or ventricular wall motion abnormalities. Healthcare professionals must remember that the electrocardiographic findings in pericarditis are not always classic and that pericarditis can occur status post cardiac ablation. PMID:25317395

Guidelines for diagnosing acute myocardial infarction (AMI) recommend adding kinetic changes to the initial cardiac troponin (cTn) blood concentration to improve AMI diagnosis. We hypothesized that kinetic changes may not be required in patients presenting with highly abnormal cTn. Patients presenting with suspected AMI to the emergency department were enrolled in a prospective diagnostic study. We assessed the positive predictive value (PPV) of initial high-sensitivity cardiac troponin T (hs-cTnT) blood concentrations alone and in combination with kinetic changes for AMI. Predefined relative changes (δ change of ≥20%) and absolute changes (Δ change ≥9.2 ng/L) within different time intervals (1 h, 2 h, and 4-14 h after presentation) were assessed. The final diagnosis was adjudicated by 2 independent cardiologists. Among 1282 patients, 213 (16.6%) patients had a final diagnosis of AMI. For AMI prediction, PPVs increased from 48.8% for an initial hs-cTnT >14 ng/L to 87.2% for >60 ng/L, whereas PPVs remained unchanged for higher hs-cTnT concentrations at baseline (87.1% for both >80 ng/L and >100 ng/L). With addition of 20% relative Δ change, PPVs were not further improved in patients with baseline hs-cTnT >80 ng/L using the 1-h (84.0%) and 2-h (88.9%) intervals, and only minimally when extending the interval to 4-14 h (91.2% for >80 ng/L and 90.4% for >100 ng/L, respectively). Similar findings were observed when applying absolute changes. In chest pain patients with highly abnormal hs-cTnT concentrations at presentation, subsequent blood draws may not be required, as they do not provide incremental diagnostic value for prediction of AMI diagnosis. © 2016 American Association for Clinical Chemistry.

Psychological traits influence autonomic nervous system recovery following esophageal intubation in health and functional chest pain.

Esophageal intubation is a widely utilized technique for a diverse array of physiological studies, activating a complex physiological response mediated, in part, by the autonomic nervous system (ANS). In order to determine the optimal time period after intubation when physiological observations should be recorded, it is important to know the duration of, and factors that influence, this ANS response, in both health and disease. Fifty healthy subjects (27 males, median age 31.9 years, range 20-53 years) and 20 patients with Rome III defined functional chest pain (nine male, median age of 38.7 years, range 28-59 years) had personality traits and anxiety measured. Subjects had heart rate (HR), blood pressure (BP), sympathetic (cardiac sympathetic index, CSI), and parasympathetic nervous system (cardiac vagal tone, CVT) parameters measured at baseline and in response to per nasum intubation with an esophageal catheter. CSI/CVT recovery was measured following esophageal intubation. In all subjects, esophageal intubation caused an elevation in HR, BP, CSI, and skin conductance response (SCR; all p < 0.0001) but concomitant CVT and cardiac sensitivity to the baroreflex (CSB) withdrawal (all p < 0.04). Multiple linear regression analysis demonstrated that longer CVT recovery times were independently associated with higher neuroticism (p < 0.001). Patients had prolonged CSI and CVT recovery times in comparison to healthy subjects (112.5 s vs 46.5 s, p = 0.0001 and 549 s vs 223.5 s, p = 0.0001, respectively). Esophageal intubation activates a flight/flight ANS response. Future studies should allow for at least 10 min of recovery time. Consideration should be given to psychological traits and disease status as these can influence recovery. © 2013 John Wiley & Sons Ltd.

A 45-year-old woman presented with a sudden episode of typical chest pain, radiating to her neck. The patient denied premature coronary artery disease in the family. Initial EKG showed normal sinus rhythm with a 1 mm ST-elevation involving lead II and lead aVF and a 1 mm ST-depression in lead V1 with associated T-wave inversion. Initial Troponin I (normal <0.4 ng/mL) and CK-MB (normal <7.7 ng/mL) were elevated at 7.82 ng/mL and 55.2 ng/mL, respectively. Six hours later, Troponin I increased to 13.44 ng/mL and CK-MB to 75.7 ng/mL. The patient underwent cardiac catheterization which did not show any significant obstructive coronary artery disease. Two days later the patient developed right-sided facial palsy. Diagnosis of Lyme disease was confirmed by ELISA with positive IgM and IgG antibodies. Treatment with intravenous ceftriaxone and oral steroids was started. Eventually resolution of symptoms and, normalization of cardiac markers and EKG changes, were achieved. This is a rare case of Lyme myocarditis associated with markedly elevated Troponin I, normal left ventricle function, and an absence of conduction abnormalities. To the best of our knowledge, Lyme myocarditis mimicking acute coronary syndrome with such high levels of Troponin I and neurologic compromise has not been previously described. Lyme myocarditis may be a challenging diagnosis in endemic areas especially in patients with coronary artery disease risk factors, presenting with typical chest pain, EKG changes and positive cardiac biomarkers. Therefore, it should be considered a differential diagnosis in patients presenting with clinical symptoms suggestive of acute coronary syndrome.

Copeptin is a marker of endogenous stress including early myocardial infarction(MI) and has value in early rule out of MI when used with cardiac troponin I(cTnI). The goal of this study was to demonstrate that patients with a normal electrocardiogram and cTnI<0.040μg/l and copeptin<14pmol/l at presentation and after 2 h may be candidates for early discharge with outpatient follow-up potentially including stress testing. This study uses data from the CHOPIN trial which enrolled 2071 patients with acute chest pain. Of those, 475 patients with normal electrocardiogram and normal cTnI(<0.040μg/l) and copeptin<14pmol/l at presentation and after 2 h were considered "low risk" and selected for further analysis. None of the 475 "low risk" patients were diagnosed with MI during the 180day follow-up period (including presentation). The negative predictive value of this strategy was 100% (95% confidence interval(CI):99.2%-100.0%). Furthermore no one died during follow up. 287 (60.4%) patients in the low risk group were hospitalized. In the "low risk" group, the only difference in outcomes (MI, death, revascularization, cardiac rehospitalization) was those hospitalized underwent revascularization more often (6.3%[95%CI:3.8%-9.7%] versus 0.5%[95%CI:0.0%-2.9%], p=.002). The hospitalized patients were tested significantly more via stress testing or angiogram (68.6%[95%CI:62.9%-74.0%] vs 22.9%[95%CI:17.1%-29.6%], p<.001). Those tested had less cardiac rehospitalizations during follow-up (1.7% vs 5.1%, p=.040). In conclusion, patients with a normal electrocardiogram, troponin and copeptin at presentation and after 2 h are at low risk for MI and death over 180days. These low risk patients may be candidates for early outpatient testing and cardiology follow-up thereby reducing hospitalization. Copyright © 2016 Elsevier Inc. All rights reserved.

Chest wall myositis in a patient with acute coronary syndrome

We describe a case of a 42-year-old man who presented to the emergency department with severe left-sided chest pain and chest tenderness of 1-day duration. The pain was episodic and was aggravated by any chest wall movement. His initial blood tests and ECG were suggestive of acute coronary syndrome (ACS). However, his pattern of pain, lack of response to opiates, raised creatine kinase and signs of pleurisy on chest radiograph raised a suspicion of an alternative diagnosis. The patient showed a dramatic response in pain relief to non-steroidal anti-inflammatory medication. He was suspected to have chest wall myositis with pleural involvement in the form of pleurodynia. His serology test was positive for coxsackie virus antibodies. We will discuss in this case report the pathognomonic features, diagnosis and treatment of a rare infectious condition known as Bornholm disease. PMID:25312897

To describe various symptoms other than pain among consecutive patients on the waiting list for possible coronary revascularisation in relation to estimated severity of chest pain. All patients were sent a postal questionnaire for symptom evaluation. All patients in western Sweden on the waiting list in September 1990 who had been referred for coronary angiography or coronary revascularisation (n = 904). 88% of the patients reported chest pain symptoms that limited their daily activities to a greater or lesser degree. Various psychological symptoms including anxiety and depression were strongly associated with the severity of pain (P < 0.001), as were sleep disturbances (P < 0.001), and dyspnoea and various psychosomatic symptoms (P < 0.001). Nevertheless only 44% of the patients reported chest pain as the major disruptive symptom, whereas the remaining 56% reported uncertainty about the future, fear, or unspecified symptoms as being the most disturbing. In a consecutive series of patients on the waiting list for possible coronary revascularisation, half the participants reported that uncertainty and fear were more disturbing than chest pain.

A 62-year old patient with a history of chronic anemia associated with malabsorption secondary to short gut syndrome, experienced acute chest pain the second hour after the transfusion of a crossmatch-compatible erythrocyte suspension. His electrocardiogram (ECG) revealed widespread ST-segment depressions and he had an elevated troponin level. Laboratory findings and physical examination did not indicate the presence of immunological or non-immunological blood transfusion reactions. Cardiac catheterization was performed and showed angiographically non-obstructive, atherosclerotic plaques and the absence of vasospasm or thrombus formation. Following antiischemic therapy his symptoms resolved completely. The ECG obtained 24 hours after the emergence of chest pain demonstrated normal sinus rhythm with no ST-T wave changes. We present a rare case of acute myocardial infarction induced following a blood transfusion. To the best of our knowledge, a few cases of acute myocardial infarction associated with blood transfusion have been formally recorded in the medical literature and the clinical experience regarding such cases is indeed quite limited. The present case is reviewed in the context of the relevant literature as a practical resource for clinical practice. Crown Copyright © 2014. Published by Elsevier Ltd. All rights reserved.

Cardiophobia: a paradigmatic behavioural model of heart-focused anxiety and non-anginal chest pain.

PubMed

Eifert, G H

1992-07-01

Cardiophobia is defined as an anxiety disorder of persons characterized by repeated complaints of chest pain, heart palpitations, and other somatic sensations accompanied by fears of having a heart attack and of dying. Persons with cardiophobia focus attention on their heart when experiencing stress and arousal, perceive its function in a phobic manner, and continue to believe that they suffer from an organic heart problem despite repeated negative medical tests. In order to reduce anxiety, they seek continuous reassurance, make excessive use of medical facilities, and avoid activities believed to elicit symptoms. The relationship of cardiophobia to illness phobia, health anxiety, and panic disorder is discussed. An integrative psychobiological model of cardiophobia is presented which includes previous learning conditions relating to experiences of separation and cardiac disease; deficient and inappropriate behavioural repertoires which constitute a psychological vulnerability for cardiophobic problems; negative life events, stressors, and conflicts in the person's present situation that trigger and contribute to the symptoms; current affective, cognitive, and behavioural symptoms and their stimulus properties; and genetic and acquired biological vulnerability factors. Finally, recommendations for the treatment of cardiophobia are derived from the model and areas of future research are outlined.

Coronary CT angiography is an effective, evidence-based strategy for evaluating acute chest pain in the emergency department for patients at low-to-intermediate risk of acute coronary syndrome. Recent multicenter trials have reported that coronary CT angiography is safe, reduces time to diagnosis, facilitates discharge, and may lower overall cost compared with routine care. Herein, we provide a 10-step approach for establishing a successful coronary CT angiography program in the emergency department. The importance of strategic planning and multidisciplinary collaboration is emphasized. Patient selection and preparation guidelines for coronary CT angiography are reviewed with straightforward protocols that can be adapted and modified to clinical sites, depending on available cardiac imaging capabilities. Technical parameters and patient-specific modifications are also highlighted to maximize the likelihood of diagnostic quality examinations. Practical suggestions for quality control, process monitoring, and standardized reporting are reviewed. Finally, the role of a "triple rule-out" protocol is featured in the context of acute chest pain evaluation in the emergency department.

Acupuncture therapy related cardiac injury.

PubMed

Li, Xue-feng; Wang, Xian

2013-12-01

Cardiac injury is the most serious adverse event in acupuncture therapy. The causes include needling chest points near the heart, the cardiac enlargement and pericardial effusion that will enlarge the projected area on the body surface and make the proper depth of needling shorter, and the incorrect needling method of the points. Therefore, acupuncture practitioners must be familiar with the points of the heart projected area on the chest and the correct needling methods in order to reduce the risk of acupuncture therapy related cardiac injury.

Events that induce emotional stress and frustration in a large number of subjects under specific circumstances, such as earthquakes, war conditions, and sporting occasions, may increase the incidence of cardiovascular events, such as acute myocardial infarction, arrhythmias, and sudden cardiac death. This report describes a married couple who expressed an apparently passionate interest in football with hazardous consequences after a tense football match during the FIFA 2014 World Championships. A series of emotional stressors initiated by defeat in this football game lead to cardiac arrest in a 58-year-old man caused by a thrombotic occlusion of the left anterior descending artery and ending in the death of the patient. An hour and 15 minutes after the onset of cardiac arrest of the patient, his 64-year-old wife also had chest pain caused by an acute midventricular takotsubo syndrome. She survived the acute stage of the disease, and there was complete resolution of the left ventricular dysfunction. Copyright © 2015 Elsevier Inc. All rights reserved.

Highly sensitive troponin T (hs-TnT) assay has improved clinical decision-making for patients admitted with chest pain. However, this assay's performance in detecting myocardial ischaemia in a lowrisk population has been poorly documented. To assess hs-TnT assay's performance to detect myocardial ischaemia at positron emission tomography/CT (PET-CT) in low-risk patients admitted with chest pain. Patients admitted for chest pain with a nonconclusive ECG and negative standard cardiac troponin T results at admission and after 6 hours were prospectively enrolled. Their hs-TnT samples were at T0, T2 and T6. Physicians were blinded to hs-TnT results. All patients underwent a PET-CT at rest and during adenosine-induced stress. All patients with a positive PET-CT result underwent a coronary angiography. Forty-eight patients were included. Six had ischaemia at PET-CT. All of them had ≥1 significant stenosis at coronary angiography. Areas under the curve (95% CI) for predicting significant ischaemia at PET-CT using hs-TnT were 0.764 (0.515 to 1.000) at T0, 0.812(0.616 to 1.000) at T2 and 0.813(0.638 to 0.989) at T6. The receiver operating characteristicbased optimal cut-off value for hs-TnT at T0, T2 and T6 needed to exclude significant ischaemia at PET-CT was <4 ng/L. Using this value, sensitivity, specificity, positive and negative predictive values of hs-TnT to predict significant ischaemia were 83%/38%/16%/94% at T0, 100%/40%/19%/100% at T2 and 100%/43%/20%/100% at T6, respectively. Our findings suggest that in low-risk patients, using the hs-TnT assay with a cut-off value of 4 ng/L demonstrates excellent negative predictive value to exclude myocardial ischaemia detection at PET-CT, at the expense of weak specificity and positive predictive value.

2017-09-24

Eosinophilic granulomatosis with polyangiitis is a rare, necrotizing systemic vasculitis associated with asthma and hypereosinophilia. Its cause and pathophysiology are still being elucidated. We report a case of eosinophilic granulomatosis with polyangiitis in a 50-year-old Caucasian woman who presented with chest pain, dyspnea at rest, fever, and periorbital swelling. She was found to have significant hypereosinophilia and cardiac tamponade physiology. A biopsy confirmed extensive infiltration of both lungs and pericardium by eosinophils. She did not have any anti-neutrophil cytoplasmic antibodies. Eosinophilic granulomatosis with polyangiitis diagnosis does not require the presence of anti-neutrophil cytoplasmic antibodies. Anti-neutrophil cytoplasmic antibody-positive and anti-neutrophil cytoplasmic antibody-negative eosinophilic granulomatosis with polyangiitis may present with different clinical phenotypes, perhaps suggesting two distinct disease etiologies and distinct pathophysiology.

Time to treatment and acute coronary syndromes: bridging the gap in rapid decision making.

Peacock, W Frank

2010-01-01

The role of cardiac biomarkers in the diagnosis, risk stratification, and treatment of patients with chest pain and suspected acute coronary syndromes (ACS) has continued to evolve. Although it is clear that troponin (Tn) measurement provides independent prognostic information in patients with suspected ACS, it is less well established that early B-type natriuretic peptide (BNP) measurement provides additional incremental prognostic information above and beyond electrocardiography and Tn measurement. It is useful to identify patients at high risk for adverse events through measurement of Tn and BNP levels so that timely treatment decisions can be made.

Comparison between manual and mechanical chest compressions during resuscitation in a pediatric animal model of asphyxial cardiac arrest

Aims Chest compressions (CC) during cardiopulmonary resuscitation are not sufficiently effective in many circumstances. Mechanical CC could be more effective than manual CC, but there are no studies comparing both techniques in children. The objective of this study was to compare the effectiveness of manual and mechanical chest compressions with Thumper device in a pediatric cardiac arrest animal model. Material and methods An experimental model of asphyxial cardiac arrest (CA) in 50 piglets (mean weight 9.6 kg) was used. Animals were randomized to receive either manual CC or mechanical CC using a pediatric piston chest compressions device (Life-Stat®, Michigan Instruments). Mean arterial pressure (MAP), arterial blood gases and end-tidal CO2 (etCO2) values were measured at 3, 9, 18 and 24 minutes after the beginning of resuscitation. Results There were no significant differences in MAP, DAP, arterial blood gases and etCO2 between chest compression techniques during CPR. Survival rate was higher in the manual CC (15 of 30 = 50%) than in the mechanical CC group (3 of 20 = 15%) p = 0.016. In the mechanical CC group there was a non significant higher incidence of haemorrhage through the endotracheal tube (45% vs 20%, p = 0.114). Conclusions In a pediatric animal model of cardiac arrest, mechanical piston chest compressions produced lower survival rates than manual chest compressions, without any differences in hemodynamic and respiratory parameters.

Small pigtail catheters appear to work as well as the traditional large-bore chest tubes in patients with traumatic pneumothorax, but it is not known whether the smaller pigtail catheters are associated with less tube-site pain. This study was conducted to compare tube-site pain following pigtail catheter or chest tube insertion in patients with uncomplicated traumatic pneumothorax. This prospective randomized trial compared 14-Fr pigtail catheters and 28-Fr chest tubes in patients with traumatic pneumothorax presenting to a level I trauma centre from July 2010 to February 2012. Patients who required emergency tube placement, those who refused and those who could not respond to pain assessment were excluded. Primary outcomes were tube-site pain, as assessed by a numerical rating scale, and total pain medication use. Secondary outcomes included the success rate of pneumothorax resolution and insertion-related complications. Forty patients were enrolled. Baseline characteristics of 20 patients in the pigtail catheter group were similar to those of 20 patients in the chest tube group. No patient had a flail chest or haemothorax. Pain scores related to chest wall trauma were similar in the two groups. Patients with a pigtail catheter had significantly lower mean(s.d.) tube-site pain scores than those with a chest tube, at baseline after tube insertion (3.2(0.6) versus 7.7(0.6); P < 0.001), on day 1 (1.9(0.5) versus 6.2(0.7); P < 0.001) and day 2 (2.1(1.1) versus 5.5(1.0); P = 0.040). The decreased use of pain medication associated with pigtail catheter was not significantly different. The duration of tube insertion, success rate and insertion-related complications were all similar in the two groups. For patients with a simple, uncomplicated traumatic pneumothorax, use of a 14-Fr pigtail catheter is associated with reduced pain at the site of insertion, with no other clinically important differences noted compared with chest tubes.

Cardiovascular injuries after trauma present with high mortality. The aim of the study was to present our experience in cardiac and great vessel injuries after chest trauma. During the 10-year period, 104 patients with cardiac (n=94) and great vessel (n=10) injuries presented to our hospital. The demographic data, mechanism of injury, location of injury, other associated injuries, timing of surgical intervention, surgical approach, and clinical outcome were reviewed. Eighty-eight (84.6%) males presented after chest trauma. The mean age of the patients was 32.5±8.2 years (range: 12-76). Penetrating injuries (62.5%) were the most common cause of trauma. Computed tomography was performed in most cases and echocardiography was used in some stable cases. Cardiac injuries mostly included the right ventricle (58.5%). Great vessel injuries involved the subclavian vein in 6, innominate vein in 1, vena cava in 1, and descending aorta in 2 patients. Early operations after admission to the emergency were performed in 75.9% of the patients. Thoracotomy was performed in 89.5% of the patients. Operative mortality was significantly high in penetrating injuries (p=0.01). Clinicians should suspect cardiac and great vessel trauma in every patient presenting to the emergency unit after chest trauma. Computed tomography and echocardiography are beneficial in the management of chest trauma. Operative timing depends on hemodynamic status, and a multidisciplinary team approach improves the patient's prognosis.

Per the American Heart Association guidelines, extracorporeal cardiopulmonary resuscitation should be considered for in-hospital patients with easily reversible cardiac arrest. However, there are currently no consensus recommendations regarding resuscitation for prolonged cardiac arrest cases. We encountered a 48-year-old man who survived a cardiac arrest that lasted approximately 1.5 hours. He visited a local hospital's emergency department complaining of chest pain and dyspnea that had started 3 days earlier. Immediately after arriving in the emergency department, a cardiac arrest occurred; he was transferred to our hospital for extracorporeal membrane oxygenation (ECMO). Resuscitation was performed with strict adherence to the American Heart Association/American College of Cardiology advanced cardiac life support guidelines until ECMO could be placed. On hospital day 7, he had a full neurologic recovery. On hospital day 58, additional treatments, including orthotopic heart transplantation, were considered necessary; he was transferred to another hospital. To our knowledge, this is the first case in South Korea of patient survival with good neurologic outcomes after resuscitation that lasted as long as 1.5 hours. Documenting cases of prolonged resuscitation may lead to updated guidelines and improvement of outcomes of similar cases in future. Copyright © 2017 The Authors.

Bone marrow harbors a population of tissue-committed stem cells that are CD34+/CXCR4+. These potential cardiac progenitors which express cardiac and endothelial markers may contribute to cardiac regeneration. The ability of injured myocardium to recruit extracardiac stem cells after injury would be beneficial to aid in myocardial repair and regeneration. The aim of this study was to answer the question whether acute myocardial infarction (AMI) related stress may trigger the increase of CD34/CXCR4+ stem cells number in peripheral blood in response to myocardial ischemic injury which might be accompanied with increased release of this population of stem cells in peripheral blood as well as to correlate this phenomenon with other clinical and laboratory parameters such as diabetes, chest pain, smoking, streptokinase administration and elevated cardiac enzymes. The study was conducted on 25 newly diagnosed AMI patients who attended the emergency department of National Heart Institute. They were compared to a control group of 25 apparently healthy sex and age matched individuals. The percentage of CD34+ cells as well as percentage of cells coexpressing CD34/CXCR4+ and their expression intensity were assessed by Flowcytometery. These parameters were correlated to other laboratory and clinical data. The absolute CD34+ as well as the CD34/CXCR4+ cell counts were significantly higher in patients upon admission in comparison to control group (P < 0.01). While CD34 expression was significantly higher in patients compared to control group, CXCR4 expression on CD34+ cells was significantly lower in patients than control group (P < 0.05). Diabetes, duration of chest pain and streptokinase administration had no significant effect on CD34/CXCR4+ number or the expression intensity of both markers (p > 0.05). Otherwise, CXCR4 intensity was lower in non-smoker than smoker patients (P < 0.05). Patients admitted with normal cardiac enzymes, including Creatine Kinase (CK) and Creatine Kinase MB fraction (CK-MB) activity, showed no significant difference in CD34/CXCR4+ number or the expression intensity of CD34 marker in comparison to those admitted with high levels of enzymes (P > 0.05). However, the expression intensity of CXCR4 was significantly low in patients admitted with elevated cardiac enzymes (P < 0.05). In conclusion, there is a pool of CD34/CXCR4+ stem cells circulating in large number in peripheral blood of AMI patients post infarction together with low CXCR4 expression on these cells which are likely to contribute to myocardial repair following the acute ischemic injury.

Investigating the effects of any intervention during cardiac arrest remains difficult. The ROSC after cardiac arrest score was introduced to facilitate comparison of rates of return of spontaneous circulation (ROSC) between different ambulance services. To study the influence of chest compression quality management (including training, real-time feedback devices, and debriefing) in comparison with conventional cardiopulmonary resuscitation (CPR), a matched-pair analysis was conducted using data from the German Resuscitation Registry, with the calculated ROSC after cardiac arrest score as the baseline. Matching for independent ROSC after cardiac arrest score variables yielded 319 matched cases from the study period (January 2007-March 2011). The score predicted a 45% ROSC rate for the matched pairs. The observed ROSC increased significantly with chest compression quality management, to 52% (P=0.013; 95% CI, 46-57%). No significant differences were seen in the conventional CPR group (47%; 95% CI, 42-53%). The difference between the observed ROSC rates was not statistically significant. Chest compression quality management leads to significantly higher ROSC rates than those predicted by the prognostic score (ROSC after cardiac arrest score). Matched-pair analysis shows that with conventional CPR, the observed ROSC rate was not significantly different from the predicted rate. Analysis shows a trend toward a higher ROSC rate for chest compression quality management in comparison with conventional CPR. It is unclear whether a single aspect of chest compression quality management or the combination of training, real-time feedback, and debriefing contributed to this result.

Data from a 1980, community-based survey of adult residents of Edgecombe County, North Carolina were analyzed to examine differences between Blacks and Whites in the reported use of medical care after experiencing chest pain. Of all adults (N = 302) with chest pain in the year prior to interview, 49 percent of Blacks and 27 percent of Whites did not see a physician following the chest pain (difference = 22%, 95% CI = 12, 33). A multivariable analysis found that although the association between race and utilization was reduced at poverty levels of income, it was not explained by differences in demographic characteristics, health status or other dimensions of access to care.

The present photocase illustrates the possible mechanism of direct cardiac injuries from broken sharp jagged fractured ends of ribs in blunt force trauma to the chest in run over traffic mishaps. We propose that the projecting fractured ends of the ribs penetrate the underlying thoracic organs due to the transient phenomenon of deformation of chest cavity under pressure in run over traffic mishaps.

The use of protocols for patients with ST-elevation myocardial infarction (MI) is growing, but no definite conclusion regarding the value of critical pathways in Europe has been drawn. The aim of this study was to investigate the impact of critical pathway on processes of care and outcome for patients presenting to the emergency department (ED) of a large urban European hospital because of possible ST-elevation MI. Critical pathways for management of acute chest pain at our ED were developed in 1998 and have been revised every year. Accordingly, the records of all patients referred in 1997 to the ED because of chest pain (before pathway implementation) and in 2001 (after last pathway revision) were reviewed. An ST-elevation MI was diagnosed at ED in 520 of 5,066 (10.3%) patients with chest pain in 1997, and in 452 of 4,843 (9.3%) patients with chest pain in 2001. Patients were managed according to the ED cardiologists' decisions in 1997, whereas they entered the pathways for ST-elevation MI in 2001, with predefined criteria for diagnosis, thrombolysis, percutaneous coronary intervention, and admission to the coronary care unit. Comparison of treatment modalities disclosed that more patients were given thrombolysis in 1997 (49 vs. 16%, p<0.05), whereas in 2001 more patients were sent to primary angioplasty (63 vs. 11%, p<0.05). Also in 2001, patients more often received aspirin (90 vs. 61%, p<0.05) and intravenous beta blockers (60 vs. 35%, p<0.05) soon after arrival at the ED. Comparison between 1997 and 2001 revealed that admission rates to the coronary care unit (69 vs. 78%, NS) and cardiac wards were similar (19 vs. 10%, NS). Conversely, compared with 1997, patients hospitalized in 2001 had a shorter length of stay (12 +/- 5 vs. 18 +/- 6 days, p<0.05), as well as fewer major adverse coronary events (21 vs. 30%, p<0.05) and lower all-cause in-hospital mortality (12 vs. 20%, p<0.05). The quality of care indicators improved with time, as door-to-electrocardiogram interval (10 +/- 6 vs. 19 +/- 9 min, p<0.05), door-to-needle time (25 +/- 10 vs. 35 +/- 10 min, p<0.05), and door-to-balloon interval (70 +/- 15 vs. 99 +/- 20 min, p<0.05) were shorter in 2001 than in 1997. A critical pathway for ST-elevation MI at the ED increases the use of evidence-based treatment strategies and improves outcome and quality of care of patients presenting to a European hospital because of acute chest pain.

To present an unusual case of spontaneous pneumomediastinum subsequent to recreational amphetamine use. A young African American adult male was admitted to internal medicine service for treatment of rhabdomyolysis secondary to methamphetamine use. On admission, he was complaining of chest pain in addition to nausea and generalized muscle aches. By his second hospital day, chest pain had resolved yet physical exam demonstrated crepitation of the anterior chest and left axilla. Portable chest x-ray revealed subcutaneous emphysema in addition to pneumomediastinum. Spontaneous pneumomediastinum is a rare complication of amphetamine use that is often associated with subcutaneous emphysema and can be diagnosed with chest x-ray. Management is conservative, with observation, pain control, and supplemental oxygen as needed.

Background The diagnosis of angina is challenging as it relies on symptom descriptions. Natural language processing (NLP) of the electronic medical record (EMR) can provide access to such information contained in free text that may not be fully captured by conventional diagnostic coding. Objective To test the hypothesis that NLP of the EMR improves angina pectoris (AP) ascertainment over diagnostic codes. Methods Billing records of in- and out-patients were searched for ICD-9 codes for AP, chronic ischemic heart disease and chest pain. EMR clinical reports were searched electronically for 50 specific non-negated natural language synonyms to these ICD-9 codes. The two methods were compared to a standardized assessment of angina by Rose questionnaire for three diagnostic levels: unspecified chest pain, exertional chest pain, and Rose angina. Results Compared to the Rose questionnaire, the true positive rate of EMR-NLP for unspecified chest pain was 62% (95%CI:55–67) vs. 51% (95%CI:44–58) for diagnostic codes (p<0.001). For exertional chest pain, the EMR-NLP true positive rate was 71% (95%CI:61–80) vs. 62% (95%CI:52–73) for diagnostic codes (p=0.10). Both approaches had 88% (95%CI:65–100) true positive rate for Rose angina. The EMR-NLP method consistently identified more patients with exertional chest pain over 28-month follow-up. Conclusion EMR-NLP method improves the detection of unspecified and exertional chest pain cases compared to diagnostic codes. These findings have implications for epidemiological and clinical studies of angina pectoris. PMID:17383310

The aim of this study was to compare in patients presenting with acute chest pain the clinical outcomes and cost-effectiveness of an accelerated diagnostic protocol utilizing contemporary technology in a chest pain unit versus routine care in an internal medicine department. Hospital and 90-day course were prospectively studied in 585 consecutive low-moderate risk acute chest pain patients, of whom 304 were investigated in a designated chest pain center using a pre-specified accelerated diagnostic protocol, while 281 underwent routine care in an internal medicine ward. Hospitalization was longer in the routine care compared with the accelerated diagnostic protocol group (p<0.001). During hospitalization, 298 accelerated diagnostic protocol patients (98%) vs. 57 (20%) routine care patients underwent non-invasive testing, (p<0.001). Throughout the 90-day follow-up, diagnostic imaging testing was performed in 125 (44%) and 26 (9%) patients in the routine care and accelerated diagnostic protocol patients, respectively (p<0.001). Ultimately, most patients in both groups had non-invasive imaging testing. Accelerated diagnostic protocol patients compared with those receiving routine care was associated with a lower incidence of readmissions for chest pain [8 (3%) vs. 24 (9%), p<0.01], and acute coronary syndromes [1 (0.3%) vs. 9 (3.2%), p<0.01], during the follow-up period. The accelerated diagnostic protocol remained a predictor of lower acute coronary syndromes and readmissions after propensity score analysis [OR = 0.28 (CI 95% 0.14-0.59)]. Cost per patient was similar in both groups [($2510 vs. $2703 for the accelerated diagnostic protocol and routine care group, respectively, (p = 0.9)]. An accelerated diagnostic protocol is clinically superior and as cost effective as routine in acute chest pain patients, and may save time and resources.

The diagnostic evaluation of acute chest pain has been augmented in recent years by advances in the sensitivity and precision of cardiac troponin assays, new biomarkers, improvements in imaging modalities, and release of new clinical decision algorithms. This progress has enabled physicians to diagnose or rule-out acute myocardial infarction earlier after the initial patient presentation, usually in emergency department settings, which may facilitate prompt initiation of evidence-based treatments, investigation of alternative diagnoses for chest pain, or discharge, and permit better utilization of healthcare resources. A non-trivial proportion of patients fall in an indeterminate category according to rule-out algorithms, and minimal evidence-based guidance exists for the optimal evaluation, monitoring, and treatment of these patients. The Cardiovascular Round Table of the ESC proposes approaches for the optimal application of early strategies in clinical practice to improve patient care following the review of recent advances in the early diagnosis of acute coronary syndrome. The following specific 'indeterminate' patient categories were considered: (i) patients with symptoms and high-sensitivity cardiac troponin <99th percentile; (ii) patients with symptoms and high-sensitivity troponin <99th percentile but above the limit of detection; (iii) patients with symptoms and high-sensitivity troponin >99th percentile but without dynamic change; and (iv) patients with symptoms and high-sensitivity troponin >99th percentile and dynamic change but without coronary plaque rupture/erosion/dissection. Definitive evidence is currently lacking to manage these patients whose early diagnosis is 'indeterminate' and these areas of uncertainty should be assigned a high priority for research.

To investigate the usefulness of stress testing before discharge in patients assessed low to intermediate risk of acute coronary syndrome (ACS). A prospective observational study was undertaken of patients presenting to the ED with suspected myocardial ischaemia. After negative initial electrocardiogram (ECG) and serum troponin testing, patients were admitted to the emergency short stay unit (ESSU) for further evaluation using a chest pain protocol that included stress testing as the final risk stratification tool. The primary outcome measure was evidence of myocardial ischaemia at stress testing. Of the 300 patients enrolled and followed up, there were no deaths at 30 days and no myocardial infarcts in patients discharged from the short stay. Two patients (0.67%) had positive serum troponin levels at 6 h after the onset of chest pain and were diagnosed with non-ST segment elevation myocardial infarctions. Three patients (1%) had abnormal stress testing and were admitted to hospital from ESSU. On review, all three patients were high risk, according to The National Heart Foundation of Australia/Cardiac Society of Australia and New Zealand guidelines. The present study showed that an ED short stay unit can effectively evaluate and manage patients with low and intermediate risk of ACS. The study suggests that patients with low and intermediate risk for ACS might safely be discharged after normal serial ECG and cardiac biomarkers, with a view to early outpatient stress testing. With strict adherence to admission criteria, there does not appear to be any benefit of stress testing before discharge. © 2010 The Authors.

Atrial fibrillation (AF) and coronary artery disease (CAD) may be encountered coincidently in a large portion of patients. However, data on coronary artery calcium burden in such patients are lacking. Thus, we sought to determine the value of cardiac computed tomography (CCT) in patients presenting with new-onset AF associated with an intermediate pretest probability for CAD admitted to a chest pain unit (CPU). Calcium scores (CS) of 73 new-onset, symptomatic AF subjects without typical clinical, electrocardiographic, or laboratory signs of acute coronary syndrome (ACS) admitted to our CPU were analyzed. In addition, results from computed tomography angiography (CTA) were related to coronary angiography findings whenever available. Calcium scores of zero were found in 25%. Median Agatston score was 77 (interquartile range: 1-270) with gender- and territory-specific dispersal. CS scores above average were present in about 50%, high (> 400)-to-very high (> 1000) CS scores were found in 22%. Overall percentile ranking showed a relative accordance to the reference percentile distribution. Additional CTA was performed in 47%, revealing stenoses in 12%. Coronary angiography was performed in 22% and resulted in coronary intervention or surgical revascularization in 7%. On univariate analysis, CS > 50th percentile failed to serve as an independent determinant of significant stenosis during catheterization. Within a CPU setting, relevant CAD was excluded or confirmed in almost 50%, the latter with a high proportion of coronary angiographies and subsequent coronary interventions, underlining the diagnostic value of CCT in symptomatic, non-ACS, new-onset AF patients when admitted to a CPU.

Societal costs of non-cardiac chest pain compared with ischemic heart disease - a longitudinal study

PubMed Central

2013-01-01

Background Non-cardiac chest pain (NCCP) is a common complaint. Our aim was to present a detailed description of the costs of patients with NCCP compared to patients with acute myocardial infarction (AMI) and Angina Pectoris (AP) from a societal perspective. Methods Data on healthcare utilization and annual societal costs, including direct healthcare costs and indirect costs due to productivity loss, were collected from different databases. The participants consisted of 199 patients from a general hospital in Sweden (99 with NCCP, 51 with AMI, 49 with AP), mean age of 67 years, 59% men. Results NCCP, AMI, and AP patients had on average 54, 50 and 65 primary care contacts and 3, 4, and 4 hospital admissions during a period of 2 years. Length of hospital stay was 6, 11 and 11 days. On average, 14%, 18%, and 25% of NCCP, AMI and AP patients were on sick-leave annually, and about 12% in each group received a disability pension. The mean annual societal costs of NCCP, AMI and AP patients were €10,068, €15,989 and €14,737. Conclusions Although the annual societal cost of NCCP patients was lower than in AMI and AP patients, the cost was still considerable (€10,068). Taken into account the high prevalence of NCCP, the cumulative annual national cost of these patients could be more than the double of AMI and AP if all patients incurred the same costs as in this study. Targeted interventions are important in order to support patients with NCCP and minimize healthcare utilization and costs. PMID:24107009

A simple method to estimate cardiac size from single frontal plane chest roentgenograms has been described. Pre- and postflight chest X-rays from Apollo 17, and Skylab 2 and 3 have been analyzed for changes in the cardiac silhouette size. The data obtained from the computed cardiothoracic areal ratios compared well with the clinical cardiothoracic diametral ratios (r = .86). Though an overall postflight decrease in cardiac size is evident, the mean difference was not statistically significant (n = 8). The individual decreases in the cardiac silhouette size postflight are thought to be due to decrements in intracardiac chamber volumes rather than in myocardial muscle mass.

A simple method to estimate cardiac size from single frontal plane chest roentgenograms has been described. Pre- and postflight chest X-rays from Apollo 17, and Skylab 2 and 3 have been analyzed for changes in the cardiac silhouette size. The data obtained from the computed cardiothoracic areal ratios compared well with the clinical cardiothoracic diametral ratios (r = .86). Though an overall postflight decrease in cardiac size is evident, the mean difference was not statistically significant (n = 8). The individual decreases in the cardiac silhouette size postflight are thought to be due to decrements in intracardiac chamber volumes rather than in myocardial muscle mass.

Blunt cardiac trauma encompasses a wide range of clinical entities, including myocardial contusion, cardiac rupture, valve avulsion, pericardial injuries, arrhythmia, and even myocardial infarction. Acute myocardial infarction due to coronary artery dissection after blunt chest trauma is rare and may be life threatening. Differential diagnosis of acute myocardial infarction from cardiac contusion at this setting is not easy. Here we demonstrated a case of blunt chest trauma, with computed tomography detected myocardium enhancement defect early at emergency department. Under the impression of acute myocardial infarction, emergent coronary angiography revealed left anterior descending artery occlusion. Revascularization was performed and coronary artery dissection was found after thrombus aspiration. Finally, the patient survived after coronary stenting. Perfusion defects of myocardium enhancement on CT after blunt chest trauma can be very helpful to suggest myocardial infarction and facilitate the decision making of emergent procedure. This valuable sign should not be missed during the initial interpretation.

Objective: To present the case of an elite female track and field athlete who suffered a pneumomediastinum resulting from a Valsalva maneuver performed while throwing the javelin. Background: Episodes of chest pain and labored breathing in athletes may be alarming. Accurate, early diagnosis is enhanced by an awareness of those relatively rare conditions that may cause these symptoms. Differential Diagnosis: Bronchial injury/fracture, retropharyngeal abscess, acute pulmonary disease, pneumomediastinum, pneumothorax, cardiac disease, allergic reaction. Treatment: The athlete was given intravenous morphine for pain, prescribed oral pain medication, and restricted from strenuous activity for 6 weeks. Aerobic exercise was allowed after pain and air in the neck subsided, which was estimated at 1 week postinjury. Uniqueness: This is a rarely reported case of a pneumomediastinum in a female and a track and field athlete. Conclusions: Medical personnel must be aware of the possibility of pneumomediastinum in track and field athletes and in female athletes and must be knowledgeable in the followup care and the safe return of the athlete to activity.

Role of multidetector computed tomography in the diagnosis and management of patients attending the rapid access chest pain clinic, The Scottish computed tomography of the heart (SCOT-HEART) trial: study protocol for randomized controlled trial

PubMed Central

2012-01-01

Background Rapid access chest pain clinics have facilitated the early diagnosis and treatment of patients with coronary heart disease and angina. Despite this important service provision, coronary heart disease continues to be under-diagnosed and many patients are left untreated and at risk. Recent advances in imaging technology have now led to the widespread use of noninvasive computed tomography, which can be used to measure coronary artery calcium scores and perform coronary angiography in one examination. However, this technology has not been robustly evaluated in its application to the clinic. Methods/design The SCOT-HEART study is an open parallel group prospective multicentre randomized controlled trial of 4,138 patients attending the rapid access chest pain clinic for evaluation of suspected cardiac chest pain. Following clinical consultation, participants will be approached and randomized 1:1 to receive standard care or standard care plus ≥64-multidetector computed tomography coronary angiography and coronary calcium score. Randomization will be conducted using a web-based system to ensure allocation concealment and will incorporate minimization. The primary endpoint of the study will be the proportion of patients diagnosed with angina pectoris secondary to coronary heart disease at 6 weeks. Secondary endpoints will include the assessment of subsequent symptoms, diagnosis, investigation and treatment. In addition, long-term health outcomes, safety endpoints, such as radiation dose, and health economic endpoints will be assessed. Assuming a clinic rate of 27.0% for the diagnosis of angina pectoris due to coronary heart disease, we will need to recruit 2,069 patients per group to detect an absolute increase of 4.0% in the rate of diagnosis at 80% power and a two-sided P value of 0.05. The SCOT-HEART study is currently recruiting participants and expects to report in 2014. Discussion This is the first study to look at the implementation of computed tomography in the patient care pathway that is outcome focused. This study will have major implications for the management of patients with cardiovascular disease. Trial registration ClinicalTrials.gov Identifier: NCT01149590 PMID:23036114

The floating cardiac fat pad-sign of occult pneumothorax.

PubMed

Kaufman, Claire; Bokhari, S A Jamal

2016-08-01

Pneumothoraces are a possible sequela of chest trauma with potential morbidity and mortality if not recognized and treated promptly. A portable supine chest radiograph is frequently the first radiologic study performed in the setting of trauma. While large pneumothoraces can be readily recognized on these radiographs, smaller pneumothoraces are missed in up to 15 % of trauma patients. There are many radiographic signs of occult pneumothoraces, and we are presenting a new radiographic sign of occult pneumothorax. The floating cardiac fat pad sign occurs when pleural air collects anteriorly and superiorly in the most non-dependent portion of the chest lifting the pericardial fat pad off the diaphragm. Lung markings are still seen surrounding the pericardial fat pad due to the inflated lower lobe of the lung resting dependently. Rapid and accurate identification of pneumothoraces is critical but often difficult on chest radiographs. Although there are many existing radiographic signs for identification of pneumothorax, prospective identification of small pneumothoraces is still relatively poor. Here, we describe an additional sign which aides in the detection of pneumothoraces, the floating cardiac fat pad. When present, this should prompt further evaluation with chest CT or upright chest radiograph.

2013-03-01

A cardio-embolic stroke as a sequela of remote blunt chest trauma is a rare clinical presentation. Blunt chest trauma can cause various acute cardiac complications like arrhythmias, cardiac contusion etc. However, delayed consequences such as left ventricular thrombus resulting in thromboembolic phenomena are reported infrequently. A 30-year-old healthy man presented to an outside facility with transient neurological deficits. An MRI brain showed lesions suggestive of embolic etiology. A trans-thoracic echocardiogram (TTE) showed a 1.5 × 1.5 cm mass present in the left ventricular (LV) apex. Patient was transferred to our institution for cardiac surgery evaluation. On detailed questioning, he reported an incident of blunt chest trauma during a martial arts exhibition fight that took place 2 years back. Given this history, a cardiac catheterization was done, which showed 30% stenosis in mid-left anterior descending artery (LAD) without any other significant obstructive lesion. A trans-esophageal echocardiogram (TEE) showed akinesis of the LV apex and confirmed TTE finding of a mass, consistent with an apical thrombus. Surgery was deferred and patient was started on anticoagulation. A cardiac MRI done 2 weeks later showed evidence of apical infarction in the LAD territory. LAD is the most commonly affected coronary vessel by blunt traumatic injuries, likely due to its vulnerable anatomical position on the anterior aspect of the heart. A variety of mechanisms including intimal tear, rupture and spasm have been implicated in the pathogenesis of myocardial infarction after blunt chest trauma.

A retrospective study of chest pain in benign asbestos pleural disease.

Allen, Roger K A; Cramond, Tess; Lennon, Deborah; Waterhouse, Mary

2011-09-01

The aims of this review were to ascertain the incidence of asbestos-related chest pain at presentation in two groups of patients referred with asbestos diseases and the demographics, comorbidities, and chest computed tomography findings associated with chest pain. Medical charts of patients presenting 1995-2008, audited for quality assurance, were chosen at random by data managers. Patients with mesothelioma, lung cancer, and angina were excluded. Rigorous attempts had been taken by the authors to exclude other causes of chest pain. There were 167 patients who were medicolegal referrals (Group 1) and 115 clinical referrals (Group 2). Although the patients in Group 1 had more severe disease generally than Group 2, the proportion with pain was not significantly different (45.5% and 55.7%, mean duration 4.8 years, range 1-22 years). Group 1 had more severe disease as a rule. However, the proportion with pain in Groups 1 and 2, respectively, was as follows: diffuse pleural thickening (50.8% and 67.6%, P=0.072), pleural plaques (47.0% and 59.7%, P=0.076), folded atelectasis (70.6% and 83.3%, P=1.000), and asbestosis (43.6% and 53.3%, P=0.346). Of all those with folded atelectasis, 73.9% had pain. Chest pain appears to be much more common in patients with benign asbestos diseases than is currently recognized, particularly in those with folded atelectasis and is not restricted to litigants. Improved recognition of this entity is needed along with practical management guidelines for the general practitioner. Further studies are envisaged by the authors. Wiley Periodicals, Inc.

Predictive ability of an early diagnostic guess in patients presenting with chest pain; a longitudinal descriptive study

PubMed Central

2010-01-01

Background The intuitive early diagnostic guess could play an important role in reaching a final diagnosis. However, no study to date has attempted to quantify the importance of general practitioners' (GPs) ability to correctly appraise the origin of chest pain within the first minutes of an encounter. Methods The validation study was nested in a multicentre cohort study with a one year follow-up and included 626 successive patients who presented with chest pain and were attended by 58 GPs in Western Switzerland. The early diagnostic guess was assessed prior to a patient's history being taken by a GP and was then compared to a diagnosis of chest pain observed over the next year. Results Using summary measures clustered at the GP's level, the early diagnostic guess was confirmed by further investigation in 51.0% (CI 95%; 49.4% to 52.5%) of patients presenting with chest pain. The early diagnostic guess was more accurate in patients with a life threatening illness (65.4%; CI 95% 64.5% to 66.3%) and in patients who did not feel anxious (62.9%; CI 95% 62.5% to 63.3%). The predictive abilities of an early diagnostic guess were consistent among GPs. Conclusions The GPs early diagnostic guess was correct in one out of two patients presenting with chest pain. The probability of a correct guess was higher in patients with a life-threatening illness and in patients not feeling anxious about their pain. PMID:20170544

Hamilton, G A

1991-01-01

A review of the literature related to recovery from acute myocardial after discharge from the hospital revealed that very little is known about the recovery period in women. The recovery period has been studied in men with the major focus on cardiac rehabilitation, return to work, and sexual activity. In this descriptive exploratory study women were compared to men in these three areas of recovery within 3 to 9 months after discharge from the hospital. There were statistically significant differences in the following areas: marital status, more women were widowed or single; women had more responsibility for household duties after acute myocardial infarction, a decrease in frequency of sexual activity, and more reports of chest pain during sexual activity. Subjects reported little or no counselling by nurses with regard to cardiac rehabilitation, return to work or household duties, and resumption of sexual activity.

Phaeochromocytoma found on cardiovascular magnetic resonance in a patient presenting with acute myocarditis: an unusual association.

Myocarditis is inflammation of the cardiac muscle. The symptoms, signs and basic investigation findings can mimic that of myocardial infarction. The most common cause is infection (most commonly viral). Cardiovascular magnetic resonance (CMR) is the gold standard non-invasive diagnostic test for potential acute myocarditis as it allows assessment of myocardial oedema and scar. A man aged 25 years was admitted with chest pain, dizziness, headache, palpitations and sweating. His troponin was mildly positive. A CMR was performed which showed mild myocarditis and a right suprarenal mass which was confirmed to be a phaeochromocytoma based on biochemistry and a dedicated imaging workup. Phaeochromocytoma can lead to cardiac involvement in the form of left ventricular dysfunction, or catecholamine-induced myocarditis. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

2007-12-01

We evaluated the analytical and clinical performance of a new ultrasensitive cardiac troponin I assay (cTnI) on the ADVIA Centaur system (TnI-Ultra). The evaluation included the determination of detection limit, within-assay and between-assay variation and comparison with two other non-ultrasensitive methods. Moreover, cTnI was determined in 120 patients with acute chest pain with three methods. To evaluate the ability of the new method to detect MI earlier, it was assayed in 8 MI patients who first tested negative then positive by the other methods. The detection limit was 0.009 microg/L and imprecision was <10% at all concentrations evaluated. In comparison with two other methods, 10% of the anginas diagnosed were recategorized to MI. The ADVIA Centaur TnI-Ultra assay presented high reproducibility and high sensitivity. The use of the recommended lower cutpoint (0.044 microg/L) implied an increased and earlier identification of MI.

Guillain-Barre syndrome is a neurologic disorder that may appear after infection or major surgery. Guillain-Barré syndrome following cardiac surgery is rare and only based on case reports, and we review all of the published cases. A 52-year-old man after 5 months suffering from chest pain was referred to our hospital and underwent coronary artery bypass graft for 3 vessel disease. The patient was discharged without complication on the 5th postoperative day. He presented Guillain-Barré syndrome after 12 months. He has not completely recovered weakness of upper extremities grade 4/5 with atrophy of both upper extremities remains after 18 months. This disorder is similar to classic GBS. It is important to be alert to de novo autoimmune neurological disorders after cardiac surgery. These disorders are similar to classic autoimmune disease and treated with standard therapies.

2006-01-01

BACKGROUND AND OBJECTIVES To examine the capacity of angina and related symptoms experienced during exercise-stress testing to detect the presence of ischemia, controlling for other clinical factors. METHOD The authors undertook a prospective study of 482 women and 425 men (mean age 58 years) undergoing exercise stress testing with myocardial perfusion imaging. One hundred forty-six women and 127 men reported chest pain, and of these, 25% of women and 66% of men had myocardial perfusion imaging evidence of ischemia during testing. The present article focuses on patients with chest pain during testing. MAIN OUTCOME MEASURES Outcome measures included chest pain localization, extension, intensity and quality, as well as the presence of various nonpain-related symptoms. Backward logistical regression analyses were performed separately on men and women who had experienced chest pain during testing. RESULTS Men who described their chest pain as ‘heavy’ were 4.6 times more likely to experience ischemia during testing (P=0.039) compared with other men, but this pain descriptor only slightly improved accuracy of prediction beyond that provided by control variables. In women, several symptoms added to the sensitivity of the prediction, such as a numb feeling in the face or neck region (OR 4.5; P=0.048), a numb feeling in the chest area (OR 14.6; P=0.003), muscle tension (OR 5.2; P=0.013), and chest pain that was described as hot or burning (OR 4.3; P=0.014). CONCLUSIONS A more refined evaluation of symptoms experienced during testing was particularly helpful in improving detection of ischemia in women, but not in men. Attention to these symptoms may favour timely diagnosis of myocardial perfusion defects in women. PMID:16639477

To develop an affordable realistic open-chest extracorporeal membrane oxygenation (ECMO) model for embedded in situ interprofessional crisis resource management training in emergency management of a post-cardiac surgery child. An innovative attachment to a high-fidelity mannequin (Laerdal Simbaby) was used to enable a cardiac tamponade/ECMO standstill scenario. Two saline bags with blood dye were placed over the mannequin's chest. A 'heart' bag with venous and arterial outlets was connected to the corresponding tubes of the ECMO circuit. The bag was divided into arterial and venous parts by loosely wrapping silicon tubing around its centre. A 'pericardial' bag was placed above it. Both were then covered by a chest skin that had a sutured silicone membrane window. False blood injected into the 'pericardial' bag caused expansion leading to (i) bulging of silastic membrane, simulating tamponade, and (ii) compression of tubing around the 'heart' bag, creating negative venous pressures and cessation of ECMO flow. In situ Simulation Paediatric Resuscitation Team Training (SPRinT) was performed on paediatric intensive care unit; the course included a formal team training/scenario of an open-chest ECMO child with acute cardiac tamponade due to blocked chest drains/debriefing by trained facilitators. Cardiac tamponade was reproducible, and ECMO flow/circuit pressure changes were effective and appropriate. There were eight participants: one cardiac surgeon, two intensivists, one cardiologist, one perfusionist and three nurses. Five of the eight reported the realism of the model and 6/8 the realism of the clinical scenario as highly effective. Eight of eight reported a highly effective impact on (i) their practice and (ii) teamwork. Six of eight reported a highly effective impact on communication skills and increased confidence in attending future real events. Innovative adaptation of a high-fidelity mannequin for open-chest ECMO simulation can achieve a realistic and reproducible training model. The impact on interprofessional team training is promising but needs to be validated further.

Zumba-induced Takotsubo cardiomyopathy: a case report.

PubMed

2018-06-10

Takotsubo cardiomyopathy or stress cardiomyopathy is characterized by transient left ventricular apical ballooning in the absence of coronary occlusion. The underlying pathophysiological mechanism is still unclear but possible causes have been proposed mainly catecholamine cardiotoxicity, followed by metabolic disturbance, coronary microvascular impairment, and multivessel epicardial coronary artery vasospasm. Takotsubo cardiomyopathy accounts for 1-2% of patients presenting with acute coronary syndrome with the majority of patients diagnosed with Takotsubo cardiomyopathy being women > 55 years of age. Here, we discuss the case of a 38-year-old woman presenting with typical chest pain, electrocardiography changes and cardiac markers consistent with acute coronary syndrome, who was subsequently diagnosed with Takotsubo cardiomyopathy. A 38-year-old healthy American woman with negative past medical history presented to our Emergency Department with chest pain developing while participating in intense outdoor physical activities (Zumba) at a fundraising event. Our patient had typical substernal chest pain induced with exercise and was relieved by sublingual nitroglycerin in the Emergency Department. The pain started after 2 h of intensive Zumba workout. On review of her history, our patient was noted to be taking spironolactone 125 mg once daily for hirsutism for the past year. Our patient denied any family history of cardiac disease or heart failure. She admitted to being a former occasional smoker and to drinking alcohol socially. She denied any illicit drug use. She works as a social worker, and reported that she does not experience much stress in her life and denied any "one big life-changing event" or any major stressful news. While in the Emergency Department, our patient was hemodynamically stable and an electrocardiography was performed and showed sinus rhythm with no ST elevation/depression but noted T-wave inversion in leads I and aVL, and T wave flattening in leads V1 and V2. Her troponin levels were 0.294 and 0.231 consecutively. An echocardiogram was done and showed hypokinetic apical and mid-distal walls and hyperdynamic basal walls of the left ventricle with an ejection fraction of 35-40%, consistent with apical ballooning syndrome. Cardiac catheterization was subsequently done and showed depressed left ventricle systolic function, ejection fraction of 30-35% with anteroapical dyskinesia and no evidence of coronary artery disease. Our patient was diagnosed with Takotsubo cardiomyopathy after fulfilling all four of the Mayo Clinic's diagnostic criteria and was subsequently treated with a beta blocker, and angiotensin-converting enzyme inhibitor. Our patient did not have one clear trigger for her overt Takotsubo cardiomyopathy other than the Zumba activity. Zumba is considered an activity with excessive sympathetic stimulation leading to catecholamine-induced microvascular spasm or through to direct myocardial toxicity, which is postulated to be behind the pathophysiology of Takotsubo cardiomyopathy. Another interesting finding in our patient was her use of spironolactone, as treatment for hirsutism, which is an aldosterone antagonist. Aldosterone actually potentiates the effects of catecholamine and thus activates the sympathetic system. Spironolactone can thus be considered as cardioprotective against the effects of catecholamine on the heart and that is why it is considered to be beneficial and subsequently improves mortality in chronic heart failure as described in several studies.

Major adverse cardiac events in endurance exercise are usually due to underlying and unsuspected heart disease. The investigators present an analysis of major adverse cardiac events that occurred during 2 consecutive annual long distance races (a 36-km beach cycling race and a 21-km half marathon) over the past 5 years. All patients with events were transported to the hospital. Most of the 62,862 participants were men (77%; mean age 40 years). Of these, 4 men (3 runners, 1 cyclist; mean age 48 years) collapsed during (n = 2) or shortly after the races, rendering a prevalence of 0.006%. Two patients collapsed after developing chest pain, 1 of whom needed resuscitation at the event site, which was successful. These patients had acute myocardial infarctions and underwent primary angioplasty. The third patient was resuscitated at the site but did not have coronary disease or inducible ventricular tachycardia or ventricular fibrillation and collapsed presumably because of catecholamine-induced ventricular fibrillation. The fourth patient experienced heat stroke and had elevated creatine kinase-MB and troponins in the absence of electrocardiographic changes. In conclusion, the risk for major adverse cardiac events during endurance sports in well-trained athletes is very low.

Cardiac visceral fat was segmented from low-dose non-contrast chest CT images using a fully automated method. Cardiac visceral fat is defined as the fatty tissues surrounding the heart region, enclosed by the lungs and posterior to the sternum. It is measured by constraining the heart region with an Anatomy Label Map that contains robust segmentations of the lungs and other major organs and estimating the fatty tissue within this region. The algorithm was evaluated on 124 low-dose and 223 standard-dose non-contrast chest CT scans from two public datasets. Based on visual inspection, 343 cases had good cardiac visceral fat segmentation. For quantitative evaluation, manual markings of cardiac visceral fat regions were made in 3 image slices for 45 low-dose scans and the Dice similarity coefficient (DSC) was computed. The automated algorithm achieved an average DSC of 0.93. Cardiac visceral fat volume (CVFV), heart region volume (HRV) and their ratio were computed for each case. The correlation between cardiac visceral fat measurement and coronary artery and aortic calcification was also evaluated. Results indicated the automated algorithm for measuring cardiac visceral fat volume may be an alternative method to the traditional manual assessment of thoracic region fat content in the assessment of cardiovascular disease risk.

Is the case-mix of patients who self-present to ED similar to general practice and other acute-care facilities?

To benchmark walk-in presentations to emergency departments (ED) with those presenting to other local acute healthcare facilities. A large teaching hospital with an annual ED census of 140, 000 adult patients and surrounding associated acute healthcare providers. A random sample of 384 patients who self-presented to the ED was obtained. Benchmarking data were drawn from two general practices; the Tower Hamlets Community Services walk-in centre (co-located on-site with the ED) and the GP-run out-of-hours service. The case-mix presenting to the ED was characterised by a higher proportion of injuries and chest pain, but fewer simple infections and non-traumatic musculoskeletal conditions as compared to other acute care facilities in our region. Patients with injuries and possible cardiac chest pain were more likely to attend the ED, and those with infection or musculoskeletal problems less likely, as compared with other acute healthcare facilities. The population presenting to the ED is distinct from that presenting to general practice, out-of-hours clinics, or walk-in centres. Published by the BMJ Publishing Group Limited.

2011-06-01

Chest pain is the most common admission diagnosis for observation unit patients. These patients often undergo cardiac stress testing to further risk stratify for coronary artery disease (CAD). The decision of whom to stress is currently based on clinical judgment. We sought to determine the influence of cardiac risk factor burden on cardiac stress test outcome for patients tested from an observation unit, inpatient or outpatient setting. We performed a retrospective observational cohort study for all patients undergoing stress testing in our institution from June 2006 through July 2007. Cardiac risk factors were collected at the time of stress testing. Risk factors were evaluated in a summative fashion using multivariate regression adjusting for age and known coronary artery disease. The model was tested for goodness of fit and collinearity and the c statistic was calculated using the receiver operating curve. A total of 4026 subjects were included for analysis of which 22% had known CAD. The rates of positive outcome were 89 (12.0%), 95 (12.6%), and 343 (16.9%) for the OU, outpatients, and hospitalized patients respectively. While the odds of a positive test outcome increased for additional cardiac risk factors, ROC curve analysis indicates that simply adding the number of risk factors does not add significant diagnostic value. Hospitalized patients were more likely to have a positive stress test, OR 1.41 (1.10 - 1.81). Our study does not support basing the decision to perform a stress test on the number of cardiac risk factors.

We report a case of a 34-year-old woman with PCOS, presenting with chest pain, onset two days before, and ST segment-elevation myocardial infarction. She was not pregnant or in a postpartum state. Subsequent cardiac angiography revealed spontaneous left anterior descending coronary artery dissections, managed by conservative approach. The patient was discharged in medical therapy after 5days. This is the first observation of spontaneous coronary artery dissection occurring in a PCOS patient. Copyright © 2016 Elsevier Inc. All rights reserved.

This study evaluated the effects of inhalation of lavender essential oil on the pain of open-heart surgery. The main complaint of patients after open-heart surgery is chest pain. Due to the side effects of opioids, it is important to use a non-invasive way to effectively relieve pain including aromatherapy with analgesics. This study was a clinical single-blind trial and was conducted on 40 patients who had open-heart surgery in the cardiac ICU of 2 Hospitals of Tehran University of Medical Sciences, 2012. Criteria included: full consciousness, spontaneous breathing ability and not using synthetic opioids within 2 hours before extubation. After extubation, the patients were asked to mark the intensity of their pain using the visual analogue scale. Then, a cotton swab which was impregnated with 2 drops of lavender essential oil 2% was placed in their oxygen mask, and they got breath for 10 minutes. 30 minutes after aromatherapy, they were asked to re-mark their pain intensity. The level of patient's pain before and after aroma therapy were compared. The pain mean level before and after inhaling lavender essential oil was 5.60 (SD = 2.262) and 4.98 (SD = 2.293), respectively (p-value>0.05). Therefore, there is no significant difference and the result of study proves that lavender essential oil inhalation has no effect on reducing the pain of open-heart surgery.

The induction of deep cerebral hypothermia via ice-cold saline aortic flush during prolonged ventricular fibrillation cardiac arrest, followed by hypothermic stasis and delayed resuscitation (emergency preservation and resuscitation), improved neurologic outcome after cardiac arrest in pigs, as compared to conventional resuscitation. We hypothesized that emergency preservation and resuscitation with chest compressions would further improve outcome in the same model. Prospective experimental study. University research laboratory. : Twenty-four female, large, white breed pigs (27-37 kg). Fifteen minutes of ventricular fibrillation cardiac arrest were followed by 20 mins of resuscitation with chest compressions (control, n = 8), deep cerebral hypothermia via 200 mL/kg 4 degrees C saline aortic flush and hypothermic stasis (emergency preservation and resuscitation, n = 8), and emergency preservation and resuscitation combined with chest compressions (emergency preservation and resuscitation plus chest compressions, n = 8). At 35 mins after cardiac arrest, cardiopulmonary bypass was initiated, followed by defibrillation. Mild hypothermia was continued for 20 hrs. Pigs were evaluated after 9 days using a neurologic deficit (neurologic deficit score: 100% = brain dead; 0%-10% = normal) and an overall performance category score (overall performance category score: 1 = normal; 2 = slightly handicapped; 3 = severely handicapped; 4 = comatose; 5 = dead/brain dead). Brain temperature decreased from 38.5 degrees C to 15.3 degrees C +/- 3.3 degrees C in the emergency preservation and resuscitation group, and to 11.3 degrees C +/- 1.2 degrees C in the emergency preservation and resuscitation plus chest compressions group. In the control group, restoration of spontaneous circulation was achieved in four out of eight pigs, and one survived to 9 days. In the emergency preservation and resuscitation group, restoration of spontaneous circulation was achieved in seven out of eight pigs and five survived; in the emergency preservation and resuscitation plus chest compressions group, all had restoration of spontaneous circulation and seven survived (restoration of spontaneous circulation, p = .08). Neurologic outcome for (median and interquartile range) the control group included overall performance category score of 3, neurologic deficit score of 45%; for the emergency preservation and resuscitation group, overall performance category score was 3 (2-5) and neurologic deficit score was 45% (36; 50) and in the emergency preservation and resuscitation plus chest compressions group, overall performance category score was 2 (1-3) and neurologic deficit score was 13% (5; 21) (overall performance category score, p = .04; neurologic deficit score emergency preservation and resuscitation vs. emergency preservation and resuscitation plus chest compressions, p = .003). Emergency preservation and resuscitation by deep cerebral hypothermia combined with chest compressions during prolonged cardiac arrest in pigs are feasible and improve neurologic outcome.

The present study was carried out for clinical evaluation of point-of-care-testing (POCT) of heart-type fatty acid-binding protein (H-FABP), Rapicheck H-FABP, for the diagnosis of acute myocardial infarction (AMI), in comparison with conventional cardiac biochemical markers such as myoglobin, creatine kinase isoenzyme MB (CK-MB), and cardiac troponin T. Whole blood samples from patients with confirmed AMI (n = 53), patients with non-AMI cardiac diseases (n = 24), and patients with non-cardiac diseases with chest pain (n = 6) were used. When a test line appeared within 15 min after the addition of 150 microL of whole blood, it was designated to be positive for H-FABP. A control line indicates a proper use of the test. On the other hand, when no test line appeared, it was negative. In the superacute phase of AMI within 3 hours, the diagnostic sensitivity of H-FABP was 93.1%, which was the highest of the four markers compared here. The diagnostic specificity in the phase for H-FABP was 64.3%, while it was 100% with cardiac troponin T. The POCT of H-FABP is thought to be practical for the detection of cardiac damage and effective for the diagnosis of AMI in superacute phase within 3 hours and/or 6 hours.

AIM To test accuracy and reproducibility of gestalt to predict obstructive coronary artery disease (CAD) in patients with acute chest pain. METHODS We studied individuals who were consecutively admitted to our Chest Pain Unit. At admission, investigators performed a standardized interview and recorded 14 chest pain features. Based on these features, a cardiologist who was blind to other clinical characteristics made unstructured judgment of CAD probability, both numerically and categorically. As the reference standard for testing the accuracy of gestalt, angiography was required to rule-in CAD, while either angiography or non-invasive test could be used to rule-out. In order to assess reproducibility, a second cardiologist did the same procedure. RESULTS In a sample of 330 patients, the prevalence of obstructive CAD was 48%. Gestalt’s numerical probability was associated with CAD, but the area under the curve of 0.61 (95%CI: 0.55-0.67) indicated low level of accuracy. Accordingly, categorical definition of typical chest pain had a sensitivity of 48% (95%CI: 40%-55%) and specificity of 66% (95%CI: 59%-73%), yielding a negligible positive likelihood ratio of 1.4 (95%CI: 0.65-2.0) and negative likelihood ratio of 0.79 (95%CI: 0.62-1.02). Agreement between the two cardiologists was poor in the numerical classification (95% limits of agreement = -71% to 51%) and categorical definition of typical pain (Kappa = 0.29; 95%CI: 0.21-0.37). CONCLUSION Clinical judgment based on a combination of chest pain features is neither accurate nor reproducible in predicting obstructive CAD in the acute setting. PMID:28400920

Mechanical versus manual chest compressions for cardiac arrest.

Brooks, Steven C; Hassan, Nizar; Bigham, Blair L; Morrison, Laurie J

2014-02-27

This is the first update of the Cochrane review on mechanical chest compression devices published in 2011 (Brooks 2011). Mechanical chest compression devices have been proposed to improve the effectiveness of cardiopulmonary resuscitation (CPR). To assess the effectiveness of mechanical chest compressions versus standard manual chest compressions with respect to neurologically intact survival in patients who suffer cardiac arrest. We searched the Cochrane Central Register of Controlled Studies (CENTRAL; 2013, Issue 12), MEDLINE Ovid (1946 to 2013 January Week 1), EMBASE (1980 to 2013 January Week 2), Science Citation abstracts (1960 to 18 November 2009), Science Citation Index-Expanded (SCI-EXPANDED) (1970 to 11 January 2013) on Thomson Reuters Web of Science, biotechnology and bioengineering abstracts (1982 to 18 November 2009), conference proceedings Citation Index-Science (CPCI-S) (1990 to 11 January 2013) and clinicaltrials.gov (2 August 2013). We applied no language restrictions. Experts in the field of mechanical chest compression devices and manufacturers were contacted. We included randomised controlled trials (RCTs), cluster RCTs and quasi-randomised studies comparing mechanical chest compressions versus manual chest compressions during CPR for patients with atraumatic cardiac arrest. Two review authors abstracted data independently; disagreement between review authors was resolved by consensus and by a third review author if consensus could not be reached. The methodologies of selected studies were evaluated by a single author for risk of bias. The primary outcome was survival to hospital discharge with good neurological outcome. We planned to use RevMan 5 (Version 5.2. The Nordic Cochrane Centre) and the DerSimonian & Laird method (random-effects model) to provide a pooled estimate for risk ratio (RR) with 95% confidence intervals (95% CIs), if data allowed. Two new studies were included in this update. Six trials in total, including data from 1166 participants, were included in the review. The overall quality of included studies was poor, and significant clinical heterogeneity was observed. Only one study (N = 767) reported survival to hospital discharge with good neurological function (defined as a Cerebral Performance Category score of one or two), demonstrating reduced survival with mechanical chest compressions when compared with manual chest compressions (RR 0.41, 95% CI 0.21 to 0.79). Data from four studies demonstrated increased return of spontaneous circulation, and data from two studies demonstrated increased survival to hospital admission with mechanical chest compressions as compared with manual chest compressions, but none of the individual estimates reached statistical significance. Marked clinical heterogeneity between studies precluded any pooled estimates of effect. Evidence from RCTs in humans is insufficient to conclude that mechanical chest compressions during cardiopulmonary resuscitation for cardiac arrest are associated with benefit or harm. Widespread use of mechanical devices for chest compressions during cardiac events is not supported by this review. More RCTs that measure and account for the CPR process in both arms are needed to clarify the potential benefit to be derived from this intervention.

The scientific basis for postoperative respiratory care.

PubMed

Branson, Richard D

2013-11-01

Postoperative pulmonary complications (PPCs) are common and expensive. Costs, morbidity, and mortality are higher with PPCs than with cardiac or thromboembolic complications. Preventing and treating PPCs is a major focus of respiratory therapists, using a wide variety of techniques and devices, including incentive spirometry, CPAP, positive expiratory pressure, intrapulmonary percussive ventilation, and chest physical therapy. The scientific evidence for these techniques is lacking. CPAP has some evidence of benefit in high risk patients with hypoxemia. Incentive spirometry is used frequently, but the evidence suggests that incentive spirometry alone has no impact on PPC. Chest physical therapy, which includes mechanical clapping and postural drainage, appears to worsen atelectasis secondary to pain and splinting. As with many past respiratory therapy techniques, the profession needs to take a hard look at these techniques and work to provide only practices based on good evidence. The idea of a PPC bundle has merit and should be studied in larger, multicenter trials. Additionally, intraoperative ventilation may play a key role in the development of PPCs and should receive greater attention.

Ultrasound assisted evaluation of chest pain in the emergency department.

Chest pain is a commonly encountered emergency department complaint, with a broad differential including several life-threatening possible conditions. Ultrasound-assisted evaluation can potentially be used to rapidly and accurately arrive at the correct diagnosis. We propose an organized, ultrasound assisted evaluation of the patient with chest pain using a combination of ultrasound, echocardiography and clinical parameters. Basic echo techniques which can be mastered by residents in a short time are used plus standardized clinical questions and examination. Information is kept on a checklist. We hypothesize that this will result in a quicker, more accurate evaluation of chest pain in the ED leading to timely treatment and disposition of the patient, less provider anxiety, a reduction in the number of diagnostic errors, and the removal of false assumptions from the diagnostic process.

To test the effectiveness of an intervention, delivered face-to-face by local firefighters, designed to increase utilization of 911 and self-administration of aspirin for seniors experiencing chest pain. King County, Washington was divided into 126 geographically distinct areas that were randomized to intervention and control areas. A mailing list identified households of seniors within these areas. More than 20,000 homes in the intervention areas were contacted by local firefighters. Data on all 911 calls for chest pain and self-administration of aspirin were collected from the medical incident report form (MIRF). The unit of analysis was the area. Firefighters delivered a heart attack survival kit (that included an aspirin) and counseled participants on the importance of aspirin and 911 use for chest pain. Main outcome measures were 911 calls for chest pain and aspirin ingestion for a chest pain event, obtained from the MIRFs that are collected by emergency medical services personnel for 2 years after the intervention. There were significantly more calls (16%) among seniors on the mailing list in the intervention than control areas in the first year after the intervention. Among the seniors who were not on the mailing list, there was little difference in the intervention and control areas. The results were somewhat sensitive to the analytical model used and to an outlier in the treatment group. A community-based firefighter intervention can be effective in increasing appropriate response to symptoms of a heart attack among elders.

Utility of the History and Physical Examination in the Detection of Acute Coronary Syndromes in Emergency Department Patients.

PubMed

Dezman, Zachary Dw; Mattu, Amal; Body, Richard

2017-06-01

Chest pain accounts for approximately 6% of all emergency department (ED) visits and is the most common reason for emergency hospital admission. One of the most serious diagnoses emergency physicians must consider is acute coronary syndrome (ACS). This is both common and serious, as ischemic heart disease remains the single biggest cause of death in the western world. The history and physical examination are cornerstones of our diagnostic approach in this patient group. Their importance is emphasized in guidelines, but there is little evidence to support their supposed association. The purpose of this article was to summarize the findings of recent investigations regarding the ability of various components of the history and physical examination to identify which patients presenting to the ED with chest pain require further investigation for possible ACS. Previous studies have consistently identified a number of factors that increase the probability of ACS. These include radiation of the pain, aggravation of the pain by exertion, vomiting, and diaphoresis. Traditional cardiac risk factors identified by the Framingham Heart Study are of limited diagnostic utility in the ED. Clinician gestalt has very low predictive ability, even in patients with a non-diagnostic electrocardiogram (ECG), and gestalt does not seem to be enhanced appreciably by clinical experience. The history and physical alone are unable to reduce a patient's risk of ACS to a generally acceptable level (<1%). Ultimately, our review of the evidence clearly demonstrates that "atypical" symptoms cannot rule out ACS, while "typical" symptoms cannot rule it in. Therefore, if a patient has symptoms that are compatible with ACS and an alternative cause cannot be identified, clinicians must strongly consider the need for further investigation with ECG and troponin measurement.

Surgical repair of right atrial wall rupture after blunt chest trauma.

2012-01-01

Right atrial wall rupture after blunt chest trauma is a catastrophic event associated with high mortality rates. We report the case of a 24-year-old woman who was ejected 40 feet during a motor vehicle accident. Upon presentation, she was awake and alert, with a systolic blood pressure of 100 mmHg. Chest computed tomography disclosed a large pericardial effusion; transthoracic echocardiography confirmed this finding and also found right ventricular diastolic collapse. A diagnosis of cardiac tamponade with probable cardiac injury was made; the patient was taken to the operating room, where median sternotomy revealed a 1-cm laceration of the right atrial appendage. This lesion was directly repaired with 4-0 polypropylene suture. Her postoperative course was uneventful, and she continued to recover from injuries to the musculoskeletal system. This case highlights the need for a high degree of suspicion of cardiac injuries after blunt chest trauma. An algorithm is proposed for rapid recognition, diagnosis, and treatment of these lesions.

The contribution of rib fractures to prolonged pain and disability may be underappreciated and undertreated. Clinicians are traditionally taught that the pain and disability of rib fractures resolves in 6 to 8 weeks. This study was a prospective observation of 203 patients with rib fractures at a level 1 trauma center. Chest wall pain was evaluated by the McGill Pain Questionnaire (MPQ) pain rating index (PRI) and present pain intensity (PPI). Prolonged pain was defined as a PRI of 8 or more at 2 months after injury. Prolonged disability was defined as a decrease in 1 or more levels of work or functional status at 2 months after injury. Predictors of prolonged pain and disability were determined by multivariate analysis. One hundred forty-five male patients and 58 female patients with a mean injury severity score (ISS) of 20 (range, 1 to 59) had a mean of 5.4 rib fractures (range, 1 to 29). Forty-four (22%) patients had bilateral fractures, 15 (7%) had flail chest, and 92 (45%) had associated injury. One hundred eighty-seven patients were followed 2 months or more. One hundred ten (59%) patients had prolonged chest wall pain and 142 (76%) had prolonged disability. Among 111 patients with isolated rib fractures, 67 (64%) had prolonged chest wall pain and 69 (66%) had prolonged disability. MPQ PPI was predictive of prolonged pain (odds ratio [OR], 1.8; 95% confidence interval [CI], 1.4 to 2.5), and prolonged disability (OR, 2.2; 95% CI, 1.5 to 3.4). The presence of significant associated injuries was predictive of prolonged disability (OR, 5.9; 95% CI, 1.4 to 29). Prolonged chest wall pain is common, and the contribution of rib fractures to disability is greater than traditionally expected. Further investigation into more effective therapies that prevent prolonged pain and disability after rib fractures is needed. Copyright © 2013 Elsevier Inc. All rights reserved.

Heart-type fatty acid-binding protein (H-FABP) as an early diagnostic biomarker in patients with acute chest pain.

Heart-type fatty acid-binding protein (H-FABP) is an emerging biomarker, which was found to be sensitive for the early diagnosis of acute myocardial infarction (AMI). We prospectively investigated the usefulness of H-FABP determination for the evaluation of acute chest pain in patients arriving at the emergency department. Fifty-four patients presenting with acute ischemic chest pain were evaluated. H-FABP was estimated at admission using latex-enhanced immunoturbidimetric assay. Serial cardiac troponin I (cTnI), creatinine kinase-MB (CK-MB) determination, ischemia workup with stress testing, and/or coronary angiogram (CAG) were performed according to standard protocols. The sensitivity and specificity of H-FABP was 89.7% and 68%, for cTnI it was 62.1% and 100%, and for CK-MB it was 44.8% and 92%, respectively for diagnosis of AMI. The sensitivity of H-FABP was found to be far superior to initial cTnI and CK-MB, for those seen within 6h (100% vs. 46.1%, 33% respectively). On further evaluation of patients with positive H-FABP and negative cTnI, 71.4% of the patients had significant lesion on CAG, indicating ischemic cause of H-FABP elevation. Six patients with normal cTnI and CK-MB with high H-FABP had ST elevation on subsequent ECGs and were taken for primary angioplasty. H-FABP is a highly sensitive biomarker for the early diagnosis of AMI. H-FABP as early marker and cTnI as late marker would be the ideal combination to cover the complete diagnostic window for AMI. Detection of myocardial injury by H-FABP may also be applied in patients with unstable angina. H-FABP can also be used as a marker for early detection of STEMI before the ECG changes become apparent.

To investigate the ability of the HEART score to predict the presence of obstructive coronary artery disease (CAD) determined by coronary computed tomography angiography (CCTA) and its ability to predict the occurrence of major adverse cardiac events (MACE) in patients referred for CCTA after emergency department (ED) presentation. From December 2011 to August 2014, 710 ED patients with chest pain who underwent CCTA within 30 days were included. The HEART score was retrospectively calculated and patients were followed for MACE, comprised of death, myocardial infarction, and revascularization. Association of CAD at CCTA in the different categories of the HEART score was analyzed using χ test. The performance of the HEART score in discriminating between those with and without obstructive CAD was evaluated by receiver operating characteristics. Kaplan-Meier analysis was used to assess MACE-free survival stratified by HEART-score categories. During median follow-up of 826 days (interquartile range: 563-1056), MACE occurred in 46 (6.5%) patients; 3 (0.4%) myocardial infarction, 8 (1.1%) death, and 36 (5.1%) revascularizations. A low HEART score was a significant predictor for MACE-free survival (P = 0.010). CCTA revealed obstructive CAD in 11.7% of patients, with no significant difference between patients with a low and intermediate/high HEART score, respectively 10.7% and 13.2% (P = 0.29). The ability of the HEART score to identify obstructive CAD was poor with an AUC of the receiver operating characteristics curve of 0.53. The HEART score does not adequately identify patients with obstructive CAD at CCTA. It does however predict occurrence of MACE in medium-term follow-up. Excluding patients from additional testing based solely on a low HEART score may lead to suboptimal patient management. CCTA had important implications on patient management and may be a more appropriate tool to further stratify risk in ED chest pain patients.

Fibroblast growth factor 2 is an essential cardioprotective factor in a closed‐chest model of cardiac ischemia‐reperfusion injury

Abstract Fibroblast growth factor 2 (FGF2) is cardioprotective in in vivo models of myocardial infarction; however, whether FGF2 has a protective role in in vivo ischemia‐reperfusion (IR) injury, a model that more closely mimics acute myocardial infarction in humans, is not known. To assess the cardioprotective efficacy of endogenous FGF2, mice lacking a functional Fgf2 gene (Fgf2−/−) and wild‐type controls were subjected to closed‐chest regional cardiac IR injury (90 min ischemia, 7 days reperfusion). Fgf2−/− mice had significantly increased myocardial infarct size and significantly worsened cardiac function compared to wild‐type controls at both 1 and 7 days post‐IR injury. Pathophysiological analysis showed that at 1 day after IR injury Fgf2−/− mice have worsened cardiac strain patterns and increased myocardial cell death. Furthermore, at 7 days post‐IR injury, Fgf2−/− mice showed a significantly reduced cardiac hypertrophic response, decreased cardiac vessel density, and increased vessel diameter in the peri‐infarct area compared to wild‐type controls. These data reveal both acute cardioprotective and a longer term proangiogenic potential of endogenous FGF2 in a clinically relevant, in vivo, closed‐chest regional cardiac IR injury model that mimics acute myocardial infarction.

The most common types of orofacial pain originate at the dental or periodontal level or in the musculoskeletal structures. However, the patient may present pain in this region even though the source is located elsewhere in the body. One possible source of heterotopic pain is of cardiac origin. Objectives: Report two cases of orofacial pain of cardiac origin and review the clinical cases described in the literature. Study Design: Description of clinical cases and review of clinical cases. Results and conclusions: Nine cases of atypical pain of cardiac origin are recorded, which include 5 females and 4 males. In craniofacial structures, pain of cardiac origin is usually bilateral. At the craniofacial level, the most frequent location described is in the throat and jaw. Pain of cardiac origin is considered atypical due to its location, although roughly 10% of the cases of cardiac ischemia manifest primarily in craniofacial structures. Finally, the differential diagnosis of pain of odontogenic origin must be taken into account with pain of non-odontogenic origin (muscle, psychogenic, neuronal, cardiac, sinus and neurovascular pain) in order to avoid diagnostic errors in the dental practice as well as unnecessary treatments. Key words:Orofacial pain, ischemic heart disease, heterotopic pain, odontalgia. PMID:22322488

A penetrating atherosclerotic ulcer rupture in the ascending aorta with hemopericardium: a case report.

2016-07-11

Acute aortic syndrome, including classic aortic dissection, intramural aortic hematoma, and penetrating atherosclerotic ulcer (PAU), is a term used to describe a group of conditions with similar clinical symptoms, but with different pathophysiological mechanisms. PAU is a lesion that penetrates the internal elastic lamina through the media. It is usually located in the descending aorta and rarely observed in the ascending aorta. A 76-year-old man with a history of essential hypertension was brought to the emergency department (ED) because of a sudden-onset chest pain at rest. He had not been taking his medication as ordered. His vital signs in the ED were a blood pressure of 82/60 mmHg, heart rate of 158 beats per min, respiratory rate of 22 breaths per min, and a body temperature of 37.2 °C. An electrocardiogram did not show an ST segment elevation, and cardiac enzymes were within normal limits. No widening mediastinum was found on chest radiography, but a large pericardial effusion with an impending cardiac tamponade was revealed on echocardiography. The diagnosis of PAU rupture in the ascending aorta with hemopericardium was made with chest computed tomography. An emergent sternotomy and ascending aorta reconstruction were performed. A ruptured ulcerative plaque through the intima to the adventitia without flap dissection in the ascending aorta was confirmed. The patient was discharged 18 days after the operation. Although PAU in the ascending aorta is uncommon, it is commonly lethal when it ruptures. With the current advances in endovascular techniques and devices, endovascular repair of PAU in the ascending aorta is currently recommended only for high-risk patients unsuitable for open repair. However, we anticipate that endovascular repair may become feasible in patients with PAU in the ascending aorta in the future.

Chronic post-sternotomy chest pain and paresthesia (PCPP) are frequently seen and reduce the quality of life. We aimed to demonstrate the efficacy and safety of gabapentin compared with diclofenac in the treatment of PCPP and to elucidate the similarities of PCPP to neuropathic pain syndromes. The prospective, randomized, open-label, blinded end-point design of study was used. One hundred and ten patients having PCPP lasting three months or more were randomized to receive 800 mg/daily gabapentin (n=55) and 75 mg/daily diclofenac (n=55) for thirty days. All patients have undergone cardiac surgery and median sternotomy. The perception of pain or paresthesia was evaluated as 0--Normal (no pain or paresthesia), 1--Mild, 2--Moderate, 3--Severe at baseline and after thirty days of treatment. Recurrences were questioned after three months. Statistical analyses were performed using independent samples t, Chi-square, continuity correction, Fisher's exact, Mann Whitney U and Kruskal Wallis tests. In gabapentin group, mean pain and paresthesia scores regressed from 2.12+/- 0.76 to 0.54+/- 0.83 (p<0.001) and from 1.72+/- 0.74 to 0.49+/- 0.62 (p<0.001), respectively. Mean pain and paresthesia scores regressed in diclofenac group from 1.93+/- 0.8 to 1.0+/- 1.13 (p<0.001) and from 1.76+/- 0.74 to 1.24+/- 0.96 (p=0.002), respectively. Although, both gabapentin and diclofenac were found to be effective without obvious side effects in the treatment of PCPP (p<0.001), gabapentin was found to be superior to diclofenac (p=0.001 and p<0.001, respectively). Adverse effects were seen in 7% of patients on gabapentin and 4% of patients on diclofenac. Results also showed that symptomatic relief with gabapentin lasts longer than diclofenac (p<0.001). Both gabapentin and diclofenac are effective in the treatment of chronic PCPP, without obvious side effects. However, gabapentin is found to be superior to diclofenac and its effects sustain longer. The results show that there may be some evidence in PCPP as a kind of neuropathic pain.

In the present study, we aimed to define the factors contributing to patient survival after treatment by cardiopulmonary resuscitation (CPR) following cardiac arrest. Retrospective analysis was performed on cardiac arrest patients (n=138) who had CPR in the emergency department (ED) at Thammasat University hospital from 2007-2009. Logistic regression was used to analyze factors that related to the sustained return of spontaneous circulation (ROSC) for 20 minutes, survival until discharge, and survival up to 1 month post discharge. The sustained ROSC was 22.5%, survival to discharge 5.6%, and survival from discharge to 1 month 3.6%. Significant factors related to sustained ROSC was the location of cardiac arrest, the cause of arrest, shockable rhythm with defibrillation, the time until chest compression, and CPR duration. The factor influencing survival to discharge was chest compression performed within 15 minutes after cardiac arrest (p = 0.048). No factor however could be attributed to survivability up to 1 month following discharge. Our findings attribute six factors associated to ROSC including the location of arrest, the cause of cardiac arrest, initial cardiac rhythm, shockable rhythm with defibrillation, the time until chest compression and CPR duration. Statistically, resuscitation performed within 15 minutes of cardiac arrest increases the survivability of patients until discharge. However no factors could be related to the percentage of patients surviving up to 1 month post discharge.

We introduce a cardiac rehabilitation program (CRP) that utilizes only a smartphone, with no external devices. As an efficient guide for cardiac rehabilitation exercise, we developed an application to automatically indicate the exercise intensity by comparing the estimated heart rate (HR) with the target heart rate zone (THZ). The HR is estimated using video images of a fingertip taken by the smartphone's built-in camera. The introduced CRP app includes pre-exercise, exercise with intensity guidance, and post-exercise. In the pre-exercise period, information such as THZ, exercise type, exercise stage order, and duration of each stage are set up. In the exercise with intensity guidance, the app estimates HR from the pulse obtained using the smartphone's built-in camera and compares the estimated HR with the THZ. Based on this comparison, the app adjusts the exercise intensity to shift the patient's HR to the THZ during exercise. In the post-exercise period, the app manages the ratio of the estimated HR to the THZ and provides a questionnaire on factors such as chest pain, shortness of breath, and leg pain during exercise, as objective and subjective evaluation indicators. As a key issue, HR estimation upon signal corruption due to motion artifacts is also considered. Through the smartphone-based CRP, we estimated the HR accuracy as mean absolute error and root mean squared error of 6.16 and 4.30bpm, respectively, with signal corruption due to motion artifacts being detected by combining the turning point ratio and kurtosis.

To date there has been limited published data presenting the characteristics and timeliness of the management in an Emergency Department (ED) for culturally and linguistically diverse (CALD) patients presenting with chest pain. This study aimed to describe the presenting characteristics and processing times for CALD patients with chest pain compared to the Australian-born population, and current guidelines. This study was a cross sectional analysis of a cohort of patients who presented with chest pain to the metropolitan hospital between 1 July 2012 and 30 June 2014. Of the total study population (n=6640), 1241 (18.7%) were CALD and 5399 (81.3%) were Australian-born. CALD patients were significantly older than Australian-born patients (mean age 62 vs 56years, p<0.001). There were no differences in the proportion of patients who had central chest pain (74.9% vs 75.7%, p=0.526); ambulance utilisation (41.7% vs 41.1%, p=0.697); and time to initial treatment in ED (21 vs 22min, p=0.375). However, CALD patients spent a significantly longer total time in ED (5.4 vs 4.3h, p<0.001). There was no difference in guideline concordance between the two groups with low rates of 12.5% vs 13%, p=0.556. Nonetheless, CALD patients were 22% (95% CI, 0.65, 0.95, p=0.015) less likely to receive the guideline management for chest pain. The initial emergency care was equally provided to all patients in the context of a low rate of concordance with three chest pain related standards from the two guidelines. Nonetheless, CALD patients spent a longer time in ED compared to the Australian-born group. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Chest pain may be due benign diseases but often suggests an association with coronary artery disease, which justifies a quick search for medical care. However, some people have anxiety disorder with symptoms that resemble clearly an acute coronary syndrome. More specifically, during a panic attack an abrupt feeling of fear accompanied by symptoms such as breathlessness, palpitations and chest pain, makes patients believe they have a heart attack and confuse physicians about the diagnosis. The association between panic disorder and coronary artery disease has been extensively studied in recent years and, although some studies have shown anxiety disorders coexisting or increasing the risk of heart disease, one causal hypothesis is still missing. The aim of this systematic review is to present the various ways in which the scientific community has been investigating the relation between chest pain, panic disorder and coronary artery disease.

A 56 year old woman was admitted to our hospital with crescendo chest pain in the last ten days. Her past history included hypertension treated by 100 mg metoprolol for more than ten years and right carotid endarterectomy. She complained headache and a treatment of 20 mg nicergoline (ergoline derivate) daily was started. Her chest pains started always one hour after the nicergoline intake. The chest pain was accompanied by breathing difficulties and sweating of 5 min duration at first but the next days it lasted longer and longer. Next morning following her admission, one hour after the nicergoline administration she had severe chest pain again. The ECG showed ST-segment elevation in inferior leads resolved after nitroglycerin administration. The angiogram revealed normal coronary artery. Nicergoline was stopped. The patient was treated with felodipine and remains free of symptoms. Nicergoline was good for head but worse for heart in this case.

Although previous investigations have suggested that 24 hours is required to exclude acute myocardial infarction in patients who are admitted to a coronary care unit for the evaluation of acute chest pain, we hypothesized that a 12-hour period might be adequate for patients with a low probability of infarction at the time of admission. Using a Bayesian model, we developed a strategy to identify candidates for a shorter period of observation from an analysis of a derivation set of 976 patients with acute chest pain who were admitted to three teaching and four community hospitals. In the derivation set, patients whose clinical characteristics in the emergency room predicted a low (less than or equal to 7 percent) probability of myocardial infarction had only a 0.4 percent risk of infarction if they had neither abnormal levels of cardiac enzymes nor recurrent ischemic pain during the first 12 hours of hospitalization. In an independent testing set of 2684 patients from the seven hospitals, 957 admitted patients (36 percent) were classified as candidates for this 12-hour period of observation according to a previously published multivariate algorithm. Few of these patients were actually transferred from a monitored setting at 12 hours. Of the 771 candidates for a 12-hour period of observation who did not have enzyme abnormalities or recurrent pain during the first 12 hours, 4 (0.5 percent) were subsequently found to have acute myocardial infarction, and only 3 (0.4 percent) died after primary cardiac arrests, all of which occurred three to five days after admission. Rates of other major cardiovascular complications were low in the patients who might have been transferred from the coronary care unit after 12 hours with this strategy. In patients with a higher initial risk of infarction, the standard strategy of 24-hour observation identified all but 11 of 739 acute myocardial infarctions (1 percent). Emergency room clinical data can be used to identify a large subgroup of patients for whom a 12-hour period of observation is normally sufficient to exclude acute myocardial infarction. Patient-specific evaluation and treatment can then proceed without the restrictions imposed by "rule-out" protocols for myocardial infarction.

The early recognition of acute coronary syndromes is a priority in health care systems, to reduce revascularization delays. In France, patients are encouraged to call emergency numbers (15, 112), which are routed to a Medical Dispatch Centre where physicians conduct an interview and decide on the appropriate response. However, the effectiveness of this system has not yet been assessed. To describe and analyse the response of emergency physicians receiving calls for chest pain in the French Emergency Medical System. From 16 November to 13 December 2009, calls to the Medical Dispatch Centre for non-traumatic chest pain were included prospectively in a multicentre observational study. Clinical characteristics and triage decisions were collected. A total of 1647 patients were included in the study. An interview was conducted with the patient in only 30.5% of cases, and with relatives, bystanders or physicians in the other cases. A Mobile Intensive Care Unit was dispatched to 854 patients (51.9%) presenting with typical angina chest pains and a high risk of cardiovascular disease. Paramedics were sent to 516 patients (31.3%) and a general practitioner was sent to 169 patients (10.3%). Patients were given medical advice only by telephone in 108 cases (6.6%). Emergency physicians in the Medical Dispatch Centre sent an effecter to the majority of patients who called the Emergency Medical System for chest pain. The response level was based on the characteristics of the chest pain and the patient's risk profile. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Non-Small Cell Lung Carcinoma: Clinical Reasoning in the Management of a Patient Referred to Physical Therapy for Costochondritis.

PubMed

Hensley, Craig P; Emerson, Alicia J

2018-06-01

Chest pain, a frequent complaint for seeking medical care, is often attributed to musculoskeletal pathology. Costochondritis is a common disorder presenting as chest pain. Initial physical therapist examination emphasizes red flag screening. Reexamination throughout the episode of care is critical, particularly when patients are not progressing and/or in the presence of complex pain presentations. The purpose of this case report is to describe the clinical reasoning process in the management of a patient referred to physical therapy with a medical diagnosis of costochondritis. A 59-year-old woman presented with a 5-month history of left-sided chest pain that had progressed to include the cervical and shoulder regions. She reported multiple psychosocial stressors; a depression screen was positive. She reported a history of asthma and smoking and improvement in recent fatigue, coughing, dyspnea, and sweating. At the initial visit, shoulder, cervical, and thoracic active and passive range of motion and joint mobility testing reproduced her pain. Allodynia was present throughout the painful areas in the left upper quarter. The patient demonstrated improvement over 30 days (4 visits). On her fifth visit (day 35), she reported an exacerbation of her chest and upper extremity pain and noted increased fatigue, sweating, dyspnea, and loss of appetite. Even though her pain was again reproduced with musculoskeletal testing, the physical therapist contacted the patient's physician regarding the change in presentation. A subsequent chest computed tomography scan revealed a non-small cell lung adenocarcinoma. Cancer can masquerade as a musculoskeletal condition. This case highlights the importance of screening, clinical reasoning, and communication throughout the episode of care, particularly in the presence of chronic pain and psychosocial stressors.

Background Under certain conditions, exertional headaches may reflect coronary ischemia. Case Report A 44-year-old woman developed intermittent exercise-induced headaches with chest tightness over a period of 10 months. Cardiac catheterization followed by acetylcholine provocation demonstrated a right coronary artery spasm with chest tightness, headache, and ischemic effect of continuous electrocardiography changes. The patient's headache disappeared following intra-arterial nitroglycerine injection. Conclusions A coronary angiogram with provocation study revealed variant angina and cardiac cephalalgia, as per the International Classification of Headache Disorders (code 10.6). We report herein a patient with cardiac cephalalgia that manifested as reversible coronary vasospasm following an acetylcholine provocation test. PMID:20607049

To explore the relationship between the heart-type fatty acid binding protein (H-FABP) gene and intramuscular fat (IMF), a polymorphism of the second exon of the H-FABP gene was investigated in 60 Three-yellow chickens (TYCs) and 60 Hetian-black chickens (HTBCs). The IMF contents of the cardiac, chest and leg muscles in HTBC were increased compared with TYC. Both TYC and HTBC populations exhibited Hardy-Weinberg Equilibrium (HWE) according to the χ(2) test. Three variations of the two birds were detected, namely, G939A, G982A and C1014T. HTBCs with the TT genotypes exhibit increased IMF content in the chest muscles compared with the TC genotype. Thus, the G982A site could be considered a genetic marker for selecting increased IMF content in the chest muscles of HTBC. The correlation coefficients revealed that H-FABP mRNA expression was negatively correlated with the IMF content in the cardiac, chest and leg muscles of HTBC and in the cardiac and chest muscles of TYC. The relative mRNA expression of H-FABP was reduced in the cardiac and leg muscles of HTBC compared with TYC, but this difference was not observed at the protein level, as assessed by Western blot analysis. These findings offer essential data that can be useful in the breeding program of HTBC and future research exploring the role of H-FABP in IMF deposition and regulation in chickens.

Three patients with signs of acute flail mitral leaflet seen on emergency department echo: a critical constellation within the focused cardiac exam

Abstract Acute flail mitral leaflet is a time‐sensitive, reversible cause of cardiogenic shock. Transthoracic echocardiography (echo) is increasingly becoming a vital tool for non‐cardiologist physicians who treat patients with undifferentiated chest pain and dyspnoea. The sonographic abnormalities seen in acute flail mitral leaflet are within the boundaries of a focused echo. Individually, these findings are non‐specific. As a constellation, however, they are highly suggestive of this disease process. We present a case series of three patients with acute flail mitral leaflet seen on emergency department echo along with a discussion of the findings and the disease itself. PMID:28191212

The clinical presentation of Takotsubo syndrome, or apical ballooning syndrome, resembles an extensive anterolateral myocardial infarction with chest pain symptoms and electrocardiographic ST-elevation or T-wave inversion noted in most patients. However, coronary arteries are invariably found to be normal or to display minimal atherosclerotic disease despite modest elevation of cardiac enzymes. Since most cases of Takotsubo syndrome occur after intense physical and/or emotional stress, catecholamine surge appears to be a common underlying mechanism. We present a case of Takotsubo syndrome, which presented with unusual symptoms and was found to be caused by pheochromocytoma. A sudden rise in blood pressure moments after completion of echocardiographic stress testing aided in uncovering the diagnosis. ©2010, Wiley Periodicals, Inc.

A 42-year-old woman with a history of aspirin-induced asthma was admitted with severe chest pain. Emergency coronary angiography revealed coronary artery spasms. The administration of vasodilators did not suppress the anginal symptoms, and the differential white blood cell count continued to show eosinophilia. The patient's symptoms of aspirin-induced asthma, eosinophilia and other allergic states led to the diagnosis of Churg-Strauss syndrome (CSS). After starting betamethasone therapy, the eosinophilia and cardiac symptoms rapidly disappeared. Although coronary vasospasms related to CSS are rare, the present case suggests that a differential white blood cell count should be obtained in patients with refractory coronary vasospasms.

Persistent gastro-oesophageal reflux symptoms despite proton pump inhibitor therapy

About one-third of patients with suspected gastro-oesophageal reflux disease (GERD) do not respond symptomatically to proton pump inhibitors (PPIs). Many of these patients do not suffer from GERD, but may have underlying functional heartburn or atypical chest pain. Other causes of failure to respond to PPIs include inadequate acid suppression, non-acid reflux, oesophageal hypersensitivity, oesophageal dysmotility and psychological comorbidities. Functional oesophageal tests can exclude cardiac and structural causes, as well as help to confi rm or exclude GERD. The use of PPIs should only be continued in the presence of acid reflux or oesophageal hypersensitivity for acid reflux-related events that is proven on functional oesophageal tests. PMID:27779277

Pregnancy-related spontaneous coronary artery dissection (P-SCAD) is a rare but life-threatening condition of the peripartum and postpartum mother. The gold standard of diagnosing P-SCAD is a left cardiac catheterization; however, this diagnostic tool may not be used early because myocardial infarction is not typically a top differential diagnosis for women and especially young pregnant women presenting with acute chest pain. Providers and registered nurses, particularly those in the prehospital setting, the emergency department, and labor and delivery units, should be aware of signs, symptoms, potential risk factors, and diagnostic results that could indicate P-SCAD and initiate early and appropriate treatment to improve maternal outcomes.

Controversies in cardiovascular care: silent myocardial ischemia

1987-01-01

The objective evidence of silent myocardial ischemia--ischemia in the absence of classical chest pain--includes ST-segment shifts (usually depression), momentary left ventricular failure, and perfusion defects on scintigraphic studies. Assessment of angina patients with 24-hour ambulatory monitoring may uncover episodes of silent ischemia, the existence of which may give important information regarding prognosis and may help structure a more effective therapeutic regimen. The emerging recognition of silent ischemia as a significant clinical entity may eventually result in an expansion of current therapy--not only to ameliorate chest pain, but to minimize or eliminate ischemia in the absence of chest pain.

Chest pain is one of the most common complaints in patients presenting to an emergency department. Delays in management due to a lack of readily available objective tests to risk stratify patients with possible acute coronary syndromes can lead to an unnecessarily lengthy admission placing pressure on hospital beds or inappropriate discharge. The need for a co-ordinated system of clinical management based on enhanced communication between departments, timely and appropriate triage, clinical investigation, diagnosis, and treatment was identified. An evidence-based Chest Pain Management Service and clinical pathway were developed and implemented, including the introduction of after-hours exercise stress testing. Between November 2005 and March 2013, 5662 patients were managed according to a Chest Pain Management pathway resulting in a reduction of 5181 admission nights by more timely identification of patients at low risk who could then be discharged. In addition, 1360 days were avoided in high-risk patients who received earlier diagnosis and treatment. The creation of a Chest Pain Management pathway and the extended exercise stress testing service resulted in earlier discharge for low-risk patients; and timely treatment for patients with positive and equivocal exercise stress test results. This service demonstrated a significant saving in overnight admissions.

The cocaine-abused heart.

PubMed

Keller, Kathryn Buchanan; Lemberg, Louis

2003-11-01

Recreational use of cocaine dates back to the Incas in South America 5000 years ago. Cocaine is derived from the leaves of Erythroxylon coca, a shrub native to South America. In the late 1800s, Sigmund Freud popularized the drug in Europe. He used cocaine to treat depression, asthma, cachexia, and for overcoming morphine addiction. Also in this period cocaine rapidly gained acceptance in surgical procedures as a local anesthetic and vasoconstrictor. Cocaine reached the United States in the early 1900s, and its popularity led President Taft to declare it public enemy number one in 1910. Cocaine became popular again in the 1980s. Currently cocaine use is responsible for more ED visits then any of the other illicit drugs. Because most cocaine users are young, they are at a lower risk for coronary artery atherosclerotic disease. An estimated 25 million people between the ages of 26 and 34 years have used cocaine at least once, 20% were women and 30% men. Habitual users of cocaine are estimated to number 1.5 million. Most cocaine-induced chest pains do not progress to MI, and in fact many originate in the chest wall. The chest pains due to cocaine, however, are induced by myocardial ischemia, a result of vasospasm and not a thrombotic occlusion of a coronary artery that has a ruptured atheromatous plaque. ECG findings can be misleading in the diagnosis because the early repolarization syndrome, a normal variant, is a frequent finding in young African American men. Measurement of cardiac troponin levels is the most reliable diagnostic test. Percutaneous coronary intervention and angioplasty, rather than thrombolysis, is the treatment of choice because intense coronary vasospasm is the primary pathophysiology in cocaine-induced MI.

Scapulothoracic bursitis as a significant cause of breast and chest wall pain: underrecognized and undertreated.

Boneti, Cristiano; Arentz, Candy; Klimberg, V Suzanne

2010-10-01

Pain is one of the most commonly reported breast complaints. Referred pain from inflammation of the shoulder bursa is often overlooked as a cause of breast pain. The objective of this study is to evaluate the role of shoulder bursitis as a cause of breast/chest pain. An IRB-approved retrospective review from July 2005 to September 2009 identified 461 patients presenting with breast/chest pain. Cases identified with a trigger point in the medial aspect of the ipsilateral scapula were treated with a bursitis injection at the point of maximum tenderness. The bursitis injection contains a mixture of local anesthetic and corticosteroid. Presenting complaint, clinical response and associated factors were recorded and treated with descriptive statistics. Average age of the study group was 53.4 ± 12.7 years, and average BMI was 30.4 ± 7.4. One hundred and three patients were diagnosed with shoulder bursitis as the cause of breast pain and received the bursitis injection. Most cases (81/103 or 78.6%) presented with the breast/chest as the site of most significant discomfort, where 8.7% (9/103) had the most severe pain at the shoulder, 3.9% (4/103) at the axilla and 3.9% (4/103) at the medial scapular border. Of the treated patients, 83.5% (86/103) had complete relief of the pain, 12.6% (13/103) had improvement of symptoms with some degree of residual pain, and only 3.9%(4/103) did not respond at all to the treatment. The most commonly associated factor to the diagnosis of bursitis was the history of a previous mastectomy, present in 27.2% (28/103) of the cases. Shoulder bursitis represents a significant cause of breast/chest pain (22.3% or 103/461) and can be successfully treated with a local injection at site of maximum tenderness in the medial scapular border.

The paper presents the results of applying nonlocal means (NLMs) approach in the problem of separating respiration and cardiac sounds in a signal recorded on a human chest wall. The performance of the algorithm was tested both by simulated and real signals. As a quantitative efficiency measure of NLM filtration, the angle of divergence between isolated and reference signal was used. It is shown that for a wide range of signal-to-noise ratios, the algorithm makes it possible to efficiently solve this problem of separating cardiac and respiration sounds in the sum signal recorded on a human chest wall.

Thyrotoxicosis influences cardiovascular hemodynamics and can induce coronary vasospasm. Patients with thyrotoxicosis-induced acute myocardial infarction (AMI) are unusual and almost all reported cases have been associated with Graves' disease. Patients with painless thyroiditis show a thyrotoxic phase during the early stages. Here we describe a very rare case of thyrotoxicosis with painless thyroiditis-induced AMI. A 35-year-old Korean man visited the emergency room for a 2-hour duration of typical AMI chest pain. The patient did not have any coronary artery disease (CAD) risk factors. The electrocardiogram showed 3 mm of ST-segment elevation in leads II, III, and aVF, which is consistent with inferior AMI. We immediately treated the patient with aspirin, clopidogrel, and nitroglycerine and performed emergent coronary angiography. Coronary angiography showed normal coronary arteries without any stenotic lesions. Consistent with AMI, cardiac enzyme levels of serum creatine kinase (CK), CK-MB, and troponin-I were also elevated. Laboratory findings showed thyrotoxicosis without any thyroid autoantibodies. A 99m-technetium scintigraphy showed markedly decreased thyroid uptake compatible with thyroiditis. We treated the patient with calcium channel blockers and nitrates. The patient spontaneously recovered normal thyroid function after 6 weeks of observation and did not complain of chest pain. Thyrotoxicosis due to painless thyroiditis provoked AMI in a young man who had no atherosclerotic coronary lesions and no CAD risk factors.

Panic attack triggering myocardial ischemia documented by myocardial perfusion imaging study. A case report

Background Chest pain, a key element in the investigation of coronary artery disease is often regarded as a benign prognosis when present in panic attacks. However, panic disorder has been suggested as an independent risk factor for long-term prognosis of cardiovascular diseases and a trigger of acute myocardial infarction. Objective Faced with the extreme importance in differentiate from ischemic to non-ischemic chest pain, we report a case of panic attack induced by inhalation of 35% carbon dioxide triggering myocardial ischemia, documented by myocardial perfusion imaging study. Discussion Panic attack is undoubtedly a strong component of mental stress. Patients with coronary artery disease may present myocardial ischemia in mental stress response by two ways: an increase in coronary vasomotor tone or a sympathetic hyperactivity leading to a rise in myocardial oxygen consumption. Coronary artery spasm was presumed to be present in cases of cardiac ischemia linked to panic disorder. Possibly the carbon dioxide challenge test could trigger myocardial ischemia by the same mechanisms. Conclusion The use of mental stress has been suggested as an alternative method for myocardial ischemia investigation. Based on translational medicine objectives the use of CO2 challenge followed by Sestamibi SPECT could be a useful method to allow improved application of research-based knowledge to the medical field, specifically at the interface of PD and cardiovascular disease.

Trastuzumab (Herceptin) is well documented in reducing suffering and mortality from breast cancer. The clinically most important side effect of Herceptin is cardiotoxicity, which is reported in 2.6% to 4.5% of patients receiving trastuzumab alone and in as many as 27% of patients when trastuzumab is combined with an anthracycline in metastatic disease. We reported the case of a 50-year-old woman who presented to our emergency department (ED) because of chest pain and shortness of breath. On physical examination, holosystolic murmur over apex could be heard. Pulmonary and abdominal examinations were unremarkable. Twelve-lead electrocardiography showed sinus tachycardia and new onset of complete left bundle-branch block. Emergent transthoracic echocardiography revealed generalized hypokinesia of left ventricle and akinesia over interventricular septum and apex. She subsequently underwent immediate coronary angiography that revealed normal coronary angiography, and left ventriculogram revealed generalized hypokinesia with severe left ventricle dysfunction with ejection fraction of 33%. During right heart catheterization and endomyocardial biopsy, cardiac tamponade developed and was successfully relieved by pericardial window. She was discharged event-free 3 weeks later with conservative treatment. Although new onset of complete left bundle-branch block in a patient with chest pain may be acute coronary syndrome, careful review of medicine history is mandatory to avoid unnecessary procedure and complications.

Despite extensive training of citizens of Seattle in cardiopulmonary resuscitation (CPR), bystanders do not perform CPR in almost half of witnessed cardiac arrests. Instructions in chest compression plus mouth-to-mouth ventilation given by dispatchers over the telephone can require 2.4 minutes. In experimental studies, chest compression alone is associated with survival rates similar to those with chest compression plus mouth-to-mouth ventilation. We conducted a randomized study to compare CPR by chest compression alone with CPR by chest compression plus mouth-to-mouth ventilation. The setting of the trial was an urban, fire-department-based, emergency-medical-care system with central dispatching. In a randomized manner, telephone dispatchers gave bystanders at the scene of apparent cardiac arrest instructions in either chest compression alone or chest compression plus mouth-to-mouth ventilation. The primary end point was survival to hospital discharge. Data were analyzed for 241 patients randomly assigned to receive chest compression alone and 279 assigned to chest compression plus mouth-to-mouth ventilation. Complete instructions were delivered in 62 percent of episodes for the group receiving chest compression plus mouth-to-mouth ventilation and 81 percent of episodes for the group receiving chest compression alone (P=0.005). Instructions for compression required 1.4 minutes less to complete than instructions for compression plus mouth-to-mouth ventilation. Survival to hospital discharge was better among patients assigned to chest compression alone than among those assigned to chest compression plus mouth-to-mouth ventilation (14.6 percent vs. 10.4 percent), but the difference was not statistically significant (P=0.18). The outcome after CPR with chest compression alone is similar to that after chest compression with mouth-to-mouth ventilation, and chest compression alone may be the preferred approach for bystanders inexperienced in CPR.

A 73-year-old woman who had been followed in our department of gynecology because of ovarian cancer since 2002, was admitted with liver dysfunction and complaining of back pain and light precordial chest pain. The chest radiograph on admission revealed a tumor in her left upper lung field, and chest CT revealed a tumor adjacent to the chest wall and mediastinum. FDG-positron emission tomography (PET) showed abnormal uptake in the tumor and Th6/7, and the subaortic lymph nodes. On the basis of these findings, primary lung cancer with bone metastasis was suspected. She had a high grade fever on admission, and blood cultures were positive for group G streptococcus. The treatment with intravenous penicillin was started. Percutaneous biopsy of the tumor in her left chest showed an abscess wall in the chest wall, but no evidence of malignancy. Transbronchial lung biopsy and CT-guided biopsy also showed no malignant cells. Since the tumor decreased in size and back pain improved gradually by only antibiotic treatment, a diagnosis of sepsis of group G streptococcus, chest wall abscess, and vertebral osteomyelitis was made. She was treated with intravenous penicillin for 4 weeks and oral amoxicillin for another 4 weeks. After 60 days of antibiotic treatment, the tumor vanished.

To determine whether dobutamine stress echocardiography (DSE) provides prognostic information beyond that available from routine clinical data, we reviewed the outcome of 210 consecutive patients referred for DSE to evaluate chest pain, perioperative risk, and myocardial viability. Dobutamine was infused in increments of 10 micrograms/kg/min in 5-minute stages to a maximum of 40 micrograms/kg/min. The dobutamine stress echocardiogram was considered abnormal only if dobutamine induced a new wall motion abnormality as determined by review of the digitized echocardiographic images in a quad screen format and on videotape. Thirty percent of tests were abnormal. An abnormal test was more common (p < or = 0.02) in men and patients with angina pectoris, in patients taking nitrate therapy, or those with prior myocardial infarction or abnormal left ventricular wall motion at rest. Twenty-two deaths, 17 of which were cardiac, occurred over a median follow-up of 240 days (range 30 to 760). Sixteen cardiac deaths occurred in the 63 patients with versus 1 cardiac death among the 147 without a new wall motion abnormality (p < or = 0.0001). Other variables associated with cardiac death (p < or = 0.05) were age > 65 years, nitrate therapy, ventricular ectopy during DSE, suspected angina pectoris, and hospitalization at the time of DSE. When cardiac death, myocardial infarction, and revascularization procedures were all considered as adverse outcomes, a new wall motion abnormality continued to be the most powerful predictor of an adverse cardiac event.(ABSTRACT TRUNCATED AT 250 WORDS)

Cardiovascular urgencies are frequent reasons for seeking medical care. Prompt and accurate medical diagnosis is critical to reduce the morbidity and mortality of these conditions. To evaluate the use of a pocket-size echocardiography in addition to clinical history and physical exam in a tertiary medical emergency care. One hundred adult patients without known cardiac or lung diseases who sought emergency care with cardiac complaints were included. Patients with ischemic changes in the electrocardiography or fever were excluded. A focused echocardiography with GE Vscan equipment was performed after the initial evaluation in the emergency room. Cardiac chambers dimensions, left and right ventricular systolic function, intracardiac flows with color, pericardium, and aorta were evaluated. The mean age was 61 ± 17 years old. The patient complaint was chest pain in 51 patients, dyspnea in 32 patients, arrhythmia to evaluate the left ventricular function in ten patients, hypotension/dizziness in five patients and edema in one patient. In 28 patients, the focused echocardiography allowed to confirm the initial diagnosis: 19 patients with heart failure, five with acute coronary syndrome, two with pulmonary embolism and two patients with cardiac tamponade. In 17 patients, the echocardiography changed the diagnosis: ten with suspicious of heart failure, two with pulmonary embolism suspicious, two with hypotension without cause, one suspicious of acute coronary syndrome, one of cardiac tamponade and one of aortic dissection. The focused echocardiography with pocket-size equipment in the emergency care may allow a prompt diagnosis and, consequently, an earlier initiation of the therapy.

This report describes a paediatric patient presenting with haemodynamically stable non-sustained ventricular tachycardia 1 day after minor blunt chest trauma. Initial laboratory studies, chest X-ray and echocardiography were normal; however, cardiac MRI revealed precordial haematoma, myocardial contusion and small pericardial effusion. Throughout her hospital course, she remained asymptomatic aside from frequent couplets and triplets of premature ventricular contractions. Ectopy was controlled with oral verapamil. This case highlights how significant cardiac injury may be missed with standard diagnostic algorithms. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Diffuse esophageal spasm (DES) has been reported as a potential cause of dysphagia or chest pain; however, the patho-physiology of DES is unclear. The aim of this study was to examine the manometric correlates of dysphagia and chest pain in this patient population. All patients undergoing manometry at our institution are entered into a prospectively maintained database. After institutional review board approval, the database was queried to identify patients meeting criteria for DES (≥20% simultaneous waves with greater than 30 mm Hg pressure in the distal esophagus). The patient-reported symptoms and manometric data, along with the results of a 24-hour pH study (if done), were extracted for further analysis. Out of 4923 patients, 240 (4.9%) met the manometric criteria for DES. Of these, 217 patients had complete manometry data along with at least one reported symptom. Of the patients with DES, 159 (73.3%) had dysphagia or chest pain as a reported symptom. Patients reporting either dysphagia or chest pain had significantly higher lower esophageal sphincter (LES) pressure than patients without these symptoms (P= 0.007). Significant association was noted between reported dysphagia and percentage of simultaneous waves. Chest pain did not correlate with percent of simultaneous waves, mean amplitude of peristalsis, or 24-hour pH score. The origin of reported chest pain in patients with DES is not clear but may be related to higher LES pressure. Simultaneous waves were associated with reported dysphagia. Using current diagnostic criteria, the term DES has no clinical relevance. © 2010 Copyright the Authors.

Spontaneous coronary artery dissection is a rare cause of acute coronary syndrome and sudden cardiac death. We report coronary artery dissection in a 36-year-old woman with retrosternal chest pain 2 weeks after abortion. Electrocardiography showed ST elevation in leads V2-V4 and ST depression in the inferior leads. Lab data were normal. Cardiac catheterization showed a suspicious thrombotic lesion at the proximal portion of the left anterior descending artery with a smooth contour consistent with distal haziness and dissection site. Final diagnosis was coronary artery dissection. At 1 week's follow-up, the patient was in good physical condition. At 1 month's follow-up, she had no complaints of discomfort. And finally, 8 months after having suffered a heart attack, she presented no evidence of angina, dyspnea, or congestive heart failure Spontaneous coronary artery dissection is a rare disease that mainly affects younger women. Compared with earlier reports, the prognosis seems to be improved by early diagnosis and interventional treatment.

The aim of this review is to give a comprehensive and concise overview of coronary embryology and normal coronary anatomy, describe common variants of normal and summarize typical patterns of anomalous coronary artery anatomy. Extensive iconography supports the text, with particular attention to images obtained in vivo using non-invasive imaging. We have divided this article into three groups, according to their frequency in the general population: Normal, normal variant and anomaly. Although congenital coronary artery anomalies are relatively uncommon, they are the second most common cause of sudden cardiac death among young athletes and therefore warrant detailed review. Based on the functional relevance of each abnormality, coronary artery anomalies can be classified as anomalies with obligatory ischemia, without ischemia or with exceptional ischemia. The clinical symptoms may include chest pain, dyspnea, palpitations, syncope, cardiomyopathy, arrhythmia, myocardial infarction and sudden cardiac death. Moreover, it is important to also identify variants and anomalies without clinical relevance in their own right as complications during surgery or angioplasty can occur. PMID:27358682

The intersection between asthma and acute chest syndrome in children with sickle-cell anaemia

2016-01-01

Acute chest syndrome is a frequent cause of acute lung disease in children with sickle-cell disease. Asthma is common in children with sickle-cell disease and is associated with increased incidence of vaso-occlusive pain events, acute chest syndrome episodes, and earlier death. Risk factors for asthma exacerbation and an acute chest syndrome episode are similar, and both can present with shortness of breath, chest pain, cough, and wheezing. Despite overlapping risk factors and symptoms, an acute exacerbation of asthma or an episode of acute chest syndrome are two distinct entities that need disease-specific management strategies. Although understanding has increased about asthma as a comorbidity in sickle-cell disease and its effects on morbidity, substantial gaps remain in knowledge about best management. PMID:27353685

OBJECTIVE: To evaluate the impact of manual vibrocompression and nasotracheal suctioning on heart (hr) and respiratory (rr) rates, peripheral oxygen saturation (SpO2), pain and respiratory distress in infants in the postoperative period of a cardiac surgery. METHODS: Randomized controlled trial, in which the assessments were performed by the same physiotherapist in two moments: before and after the procedure. The infants were randomly divided into two groups: Intervention (IG), with manual chest vibrocompression, nasotracheal suctioning and resting; and Control CG), with 30 minutes of rest. Cardiorespiratory data (SpO2; hr; rr) were monitored and the following scales were used: Neonatal Infant Pain Scale (NIPS), for pain evaluation, and Bulletin of Silverman-Andersen (BSA), for respiratory distress assessment. The data were verified by analysis of variance (ANOVA) for repeated measures, being significant p<0.05. RESULTS: 20 infants with heart disease, ten in each group (seven acyanotic and three cyanotic) were enrolled, with ages ranging from zero to 12 months. In the analysis of the interaction between group and time, there was a significant difference in the variation of SpO2 (p=0.016), without changes in the other variables. Considering the main effect on time, only rr showed a significant difference (p=0.001). As for the group main effect, there were no statistical differences (SpO2 - p=0.77, hr - p=0.14, rr - p=0.17, NIPS - p=0.49 and BSA - p=0.51 ). CONCLUSIONS: The manual vibrocompression and the nasotracheal suctioning applied to infants in postoperative of cardiac surgery did not altered SpO2 and rr, and did not trigger pain and respiratory distress.

Current research suggests that pain is a relatively common phenomenon with 60-90% of patients presenting to emergency departments reporting pain (e.g., chest pain, trauma, extremity fractures and migraine headache) that require treatment [Hogan, S.L., 2005. Patient satisfaction with pain management in the emergency department. Advanced Emergency Nursing Journal 27(4), 284-294]. This article explores the use of conceptual theoretical empirical (C-T-E) framework to guide a senior nursing student in a case study of patient with chest pain. The Middle Range Theory of Pain described by Good [Good, M., 1998. A middle-range theory of acute pain management: use in research. Nursing Outlook 46(3), 120-124] and Melzack's [Melzack, R., 1987. The short-form McGill pain questionnaire. Pain, 30, 191-197] short form McGill pain questionnaire were applied along with the Prince Edward Island conceptual model (PEICM) for nursing. Results indicate that the nursing student increased her ability to work in partnership, assess relevant and specific information, and identify a number of strategies to help the patient achieve pain control by using a complement of pharmacological and non-pharmacological interventions. Moreover, the C-T-E approach provided an organized and systematic theoretical approach for the nursing student to assist a patient in pain control.

Scoring systems are developed to assist clinicians in making a diagnosis. However, their uptake is often limited because they are cumbersome to use, requiring information on many predictors, or complicated calculations. We examined whether, and how, simplifications affected the performance of a validated score for identifying adults with chest pain in an emergency department who have low risk of major adverse cardiac events. We simplified the Emergency Department Assessment of Chest pain Score (EDACS) by three methods: (1) giving equal weight to each predictor included in the score, (2) reducing the number of predictors, and (3) using both methods--giving equal weight to a reduced number of predictors. The diagnostic accuracy of the simplified scores was compared with the original score in the derivation (n = 1,974) and validation (n = 909) data sets. There was no difference in the overall accuracy of the simplified versions of the score compared with the original EDACS as measured by the area under the receiver operating characteristic curve (0.74 to 0.75 for simplified versions vs. 0.75 for the original score in the validation cohort). With score cut-offs set to maintain the sensitivity of the combination of score and tests (electrocardiogram and cardiac troponin) at a level acceptable to clinicians (99%), simplification reduced the proportion of patients classified as low risk from 50% with the original score to between 22% and 42%. Simplification of a clinical score resulted in similar overall accuracy but reduced the proportion classified as low risk and therefore eligible for early discharge compared with the original score. Whether the trade-off is acceptable, will depend on the context in which the score is to be used. Developers of clinical scores should consider simplification as a method to increase uptake, but further studies are needed to determine the best methods of deriving and evaluating simplified scores.

Patients in various areas of medicine report symptoms that are unexplained by other medical reasons than psychological/psychiatric. Some of them urgently seek treatment due to cardiovascular complaints, mostly rapid heart rate, palpitations and chest pain. Typical cardiac investigations, usually showing no organic reasons for these conditions, bring little information about stressful life events and psychological predispositions of these patients. Identification of coexistence of "cardiac" symptoms with other symptoms typical for neurotic disorders and difficult life circumstances may facilitate not only psychiatric diagnosis but also evaluation by cardiologists, primary care physicians, and other specialists. To determine the psychosocial context of psychogenic "pseudocardiac" symptoms and their coexistence with other symptoms in patients with neurotic disorders. Medical records of patients from the years 1980-2002 that included self-administered questionnaires transformed into an anonymised database were examined. An analysis of the relationship between symptoms reported in the Symptom Checklist and biographical circumstances described in the Life Inventory before admission to a psychotherapy day clinic for patients with neurotic disorders was performed using simple logistic regression with estimation of odds ratios and their 95% confidence intervals. The symptoms of tachycardia/palpitations and chest pain were very common, present in most subjects, and were significantly associated with such circumstances as suboptimal conflict solving by passive aggression or quarrels, uncertainty in the relationship, a sense of being inferior to the partner, and poor financial situation. In addition, these "pseudocardiac" symptoms were also associated with such childhood reminiscences as origin from a large low income family, feeling that the family of origin was inferior to others, and experience of parental hostility or lack of support. Physicians of all specialties who deal with patients experiencing pseudocardiac symptoms should expect their psychological background and perform a simple interview to identify the presence of adverse biographical circumstances described above. Identification and discussing these difficult experiences with the patients may help to convince them to seek psychological support or psychotherapy.

A multifactorial aetiology of coronary artery disease (CAD) has been established in the recent past. Extensive research is now underway to understand the mechanisms responsible for plaque vulnerability. The identification of a novel biomarker that will help in the assessment of plaque status is urgently needed for the purpose of patient stratification and prognostication. The aim of the present study was to evaluate leptin, pregnancy-associated plasma protein A (PAPP-A) and C-reactive protein (CRP) levels in patients with acute coronary syndrome and to assess their diagnostic efficacy in the identification of vulnerable plaques. The study group comprised 105 patients who had chest pain along with ECG changes (ST elevation, ST depression, T inversion) and raised cardiac enzyme levels. Sixty-two patients with chest pain and ECG changes but with normal cardiac enzyme profiles were included in the control group. Lipid profiles, and leptin, PAPP-A and CRP levels were assessed in these two groups. Receiver operating characteristics (ROC) curves were plotted to determine the utility of the parameters under study as markers of plaque vulnerability. Significantly higher levels of serum lipoprotein (a), leptin, PAPP-A and high-sensitivity CRP (hs-CRP) were observed in the cases than in the controls. A positive correlation was observed between CRP and PAPP-A levels as well as CRP and leptin concentrations. ROC curve analysis revealed similar efficacies of CRP and PAPP-A levels in their ability to detect unstable plaques with areas under the curve of 0.762 and 0.732, respectively. Multivariate analysis established the superiority of hs-CRP as a predictor of plaque instability. Our study highlights the utility of both CRP and PAPP-A levels as determinants of plaque instability. Our findings necessitate population-based follow-up studies to establish the superiority of either of the two biomarkers in the field of preventive cardiology.

Effects of depth and chest volume on cardiac function during breath-hold diving.

2009-07-01

Cardiac response to breath-hold diving in human beings is primarily characterized by the reduction of both heart rate and stroke volume. By underwater Doppler-echocardiography we observed a "restrictive/constrictive" left ventricular filling pattern compatible with the idea of chest squeeze and heart compression during diving. We hypothesized that underwater re-expansion of the chest would release heart constriction and normalize cardiac function. To this aim, 10 healthy male subjects (age 34.2 +/- 10.4) were evaluated by Doppler-echocardiography during breath-hold immersion at a depth of 10 m, before and after a single maximal inspiration from a SCUBA device. During the same session, all subjects were also studied at surface (full-body immersion) and at 5-m depth in order to better characterize the relationship of echo-Doppler pattern with depth. In comparison to surface immersion, 5-m deep diving was sufficient to reduce cardiac output (P = 0.042) and increase transmitral E-peak velocity (P < 0.001). These changes remained unaltered at a 10-m depth. Chest expansion at 10 m decreased left ventricular end-systolic volume (P = 0.024) and increased left ventricular stroke volume (P = 0.024). In addition, it decreased transmitral E-peak velocity (P = 0.012) and increased deceleration time of E-peak (P = 0.021). In conclusion the diving response, already evident during shallow diving (5 m) did not progress during deeper dives (10 m). The rapid improvement in systolic and diastolic function observed after lung volume expansion is congruous with the idea of a constrictive effect on the heart exerted by chest squeeze.

Draining of the chest cavity with two chest tubes after pulmonary lobectomy is a common practice. The objective of this study was to evaluate whether using two tubes after a pulmonary lobectomy is more effective than using a single tube. We performed a meta-analysis of five randomized studies that compared the single chest tube with double chest tube application after pulmonary lobectomy. The primary end-point was amount of drainage and duration of chest tube drainage. The secondary end-points were the patient's numbers of new drain insertion after operation, hospital stay after operation, the patient's numbers of subcutaneous emphysema after operation, the patient's numbers of residual pleural air space, pain score, the number of patients who need thoracentesis, and cost. Five randomized controlled trials totaling 502 patients were included. Meta-analysis results are as follows: There were statistically significant differences in amount of drainage (risk ratio [RR] = -0.15; 95% confidence interval [CI] = -3.17, -0.12, P = 0. 03), duration of chest tube drainage (RR = -0.43; 95% CI = -0.57, -0.19, P = 0.02), pain score (P < 0.05). Compared with patients receiving the double chest tube group, there were no statistically significant differences between the two groups with regard to the patient's numbers of new drain insertion after operation. Compared with the double chest tube, the single chest tube significantly decreases amount of drainage, duration of chest tube drainage, pain score, the number of patients who need thoracentesis, and cost. Although there is convincing evidence to confirm the results mentioned herein, they still need to be confirmed by large-sample, multicenter, randomized, controlled trials.

Kinesiology taping (KT) is a rehabilitative technique performed by the cutaneous application of a special elastic tape. We tested the safety and efficacy of KT in reducing postoperative chest pain after lung lobectomy. One-hundred and seventeen consecutive patients, both genders, age 18-85, undergoing lobectomy for lung cancer between January 2013 and July 2015 were initially considered. Lobectomies were performed by the same surgical team, with thoracotomy or video-assisted thoracoscopic surgery (VATS) access. Exclusion criteria (n = 25 patients) were: previous KT exposure, recent trauma, pre-existing chest pain, lack of informed consent, >24-h postoperative intensive care unit treatment. After surgery, the 92 eligible patients were randomized to KT experimental group (n = 46) or placebo control group (n = 46). Standard postoperative analgesia was administered in both groups (paracetamol/non-steroidal anti-inflammatory drugs, epidural analgesia including opioids), with supplemental analgesia boluses at patient request. On postoperative day 1 in addition, in experimental group patients a specialized physiotherapist applied KT, with standardized tape length, tension and shape, over three defined skin areas: at the chest access site pain trigger point; over the ipsilateral deltoid/trapezius; lower anterior chest. In control group, usual dressing tape mimicking KT was applied over the same areas, as placebo. Thoracic pain severity score [visual analogue scale (VAS) ranging 0-10] was self-assessed by all patients on postoperative days 1, 2, 5, 8, 9 and 30. The KT group and the control group had similar demographics, lung cancer clinico-pathological features and thoracotomy/VATS ratio. Postoperatively, the two groups also resulted similar in supplemental analgesia, complication rate, mean duration of chest drainage and length of stay. There were no adverse events with KT application. After tape application, KT patients reported overall less thoracic pain than the control group, the difference being significant on postoperative day 5 [median VAS, 2 (interquartile range, 1-3) vs 3 (2-5), P < 0.01] and day 8 [median VAS, 1 (0-2) vs 2 (1-3), P < 0.05]. Moreover, on postoperative day 30 persistence of chest pain (VAS ≥3) was reported less frequently by the KT group than by the control group (7 vs 24%; P = 0.03). KT after lung lobectomy is a safe and effective auxiliary technique for chest pain control. ISRCTN37253470. © The Author 2016.

As part of the American College of Cardiology Adult Congenital and Pediatric Cardiology Section effort to develop quality metrics (QMs) for ambulatory pediatric practice, the chest pain subcommittee aimed to develop QMs for evaluation of chest pain. A group of 8 pediatric cardiologists formulated candidate QMs in the areas of history, physical examination, and testing. Consensus candidate QMs were submitted to an expert panel for scoring by the RAND-UCLA modified Delphi process. Recommended QMs were then available for open comments from all members. These QMs are intended for use in patients 5-18 years old, referred for initial evaluation of chest pain in an ambulatory pediatric cardiology clinic, with no known history of pediatric or congenital heart disease. A total of 10 candidate QMs were submitted; 2 were rejected by the expert panel, and 5 were removed after the open comment period. The 3 approved QMs included: (1) documentation of family history of cardiomyopathy, early coronary artery disease or sudden death, (2) performance of electrocardiogram in all patients, and (3) performance of an echocardiogram to evaluate coronary arteries in patients with exertional chest pain. Despite practice variation and limited prospective data, 3 QMs were approved, with measurable data points which may be extracted from the medical record. However, further prospective studies are necessary to define practice guidelines and to develop appropriate use criteria in this population. © 2017 Wiley Periodicals, Inc.

The objectives were to determine if an emergency department (ED) could improve the adherence to a door-to-electrocardiogram (ECG) time goal of 10 minutes or less for patients who presented to an ED with chest pain and the effect of this adherence on door-to-balloon (DTB) time for ST-segment elevation myocardial infarction (STEMI) cardiac catheterization (cath) alert patients. This was a planned 1-month before-and-after interventional study design for implementing a new process for obtaining ECGs in patients presenting to the study ED with chest pain. Prior to the change, patients were registered and triaged before an ECG was obtained. The new procedure required registration clerks to identify those with chest pain and directly overhead page or call a designated ECG technician. This technician had other ED duties, but prioritized performing ECGs and delivering them to attending physicians. A full registration process occurred after the clinical staff performed their initial assessment. The primary outcome was the total percentage of patients with chest pain who received an ECG within 10 minutes of ED arrival. The secondary outcome was DTB time for patients with STEMI who were emergently cath alerted. Data were analyzed using mean differences, 95% confidence intervals (CIs), and relative risk (RR) regression to adjust for possible confounders. A total of 719 patients were studied: 313 before and 405 after the intervention. The mean (+/-standard deviation [SD]) age was 50 (+/-16) years, 54% were women, 57% were African American, and 36% were white. Patients walked in 89% of the time; 11% arrived by ambulance. Thirty-nine percent were triaged as emergent and 61% as nonemergent. Patients presented during daytime 68% of the time, and 32% presented during the night. Before the intervention, 16% received an ECG at 10 minutes or less. After the intervention, 64% met the time requirement, for a mean difference of 47.3% (95% CI = 40.8% to 53.3%, p < 0.0001). Results were not affected by age, sex, race, mode of arrival, triage classification, or time of arrival. For patients with STEMI cath alerts, four were seen before and seven after the intervention. No patients before the intervention had ECG time within 10 minutes, and one of four had DTB time of <90 minutes. After the intervention, all seven patients had ECG time within 10 minutes; the three arriving during weekday hours when the cath team was on site had DTB times of <90 minutes, but the four arriving at night and on weekends when the cath team was off site had DTB times of >90 minutes. The overall percentage of patients with a door-to-ECG time within 10 minutes improved without increasing staffing. An ECG was performed within 10 minutes of arrival for all patients who were STEMI cath alerted, but DTB time under 90 minutes was achieved only when the cath team was on site.

Targeting TRPV1 and TRPV2 for potential therapeutic interventions in cardiovascular disease.

PubMed

Robbins, Nathan; Koch, Sheryl E; Rubinstein, Jack

2013-06-01

Cardiovascular disease is a leading cause of morbidity and mortality worldwide, encompassing a variety of cardiac and vascular conditions. Transient receptor potential vanilloid (TRPV) channels, specifically TRPV type 1 (TRPV1) and TRPV type 2 (TRPV2), are relatively recently described channels found throughout the body including within and around the cardiovascular system. They are activated by a variety of stimuli including high temperatures, stretch, and pharmacologic and endogenous ligands. The TRPV1 channel has been found to be an important player in the pathway of the detection of chest pain after myocardial injury. Activation of peripheral TRPV1 via painful stimuli or capsaicin has been shown to have cardioprotective effects, whereas genetic abrogation of TRPV1 results in increased myocardial damage after ischemia and reperfusion injury in comparison to wild-type mice. Furthermore, blood pressure changes have been noted upon TRPV1 stimulation. Similarly, the TRPV2 channel has also been associated with changes in blood pressure and cardiac function depending on how and where the channel is activated. Interestingly, overexpression of TRPV2 channels in the heart induces dystrophic cardiomyopathy; however, stimulation under physiologic conditions leads to improved cardiac function. Probenecid, a TRPV2 agonist, has been studied as a model therapy for its inotropic effects and potential use in the treatment of cardiomyopathy. In this review, we present an up to date account of the growing evidence that supports the study of TRPV1 and TRPV2 channels as targets for therapeutic agents of cardiovascular diseases.

Although somatic symptoms are common complaints of patients with major depressive disorder (MDD), their associations with suicide are still unclear. A total of 811 MDD outpatients of aged between 18 to 64 years were enrolled nationwide in Korea with the suicidality module of the Mini-International Neuropsychiatric Interview (MINI) and the Depression and Somatic Symptom Scale (DSSS). On stepwise regression analysis, current suicidality scores were most strongly associated with chest pain in men, and neck or shoulder pain in women. Severe chest pain was associated with higher current suicidality scores in men than in women, whereas severe neck or shoulder pain showed no significant differences between the genders. In conclusion, MDD patients of both sexes with suicidal ideation showed significantly more frequent and severe somatic symptoms than those without. Current suicidal risk was associated with chest pain in men, and neck or shoulder pain in women. We suggest that clinicians pay attention to patients' somatic symptoms in real world practice.

Pediatric in-hospital cardiac arrest cardiopulmonary resuscitation quality metrics have been reported in few children less than 8 years. Our objective was to characterize chest compression fraction, rate, depth, and compliance with 2015 American Heart Association guidelines across multiple pediatric hospitals. Retrospective observational study of data from a multicenter resuscitation quality collaborative from October 2015 to April 2017. Twelve pediatric hospitals across United States, Canada, and Europe. In-hospital cardiac arrest patients (age < 18 yr) with quantitative cardiopulmonary resuscitation data recordings. None. There were 112 events yielding 2,046 evaluable 60-second epochs of cardiopulmonary resuscitation (196,669 chest compression). Event cardiopulmonary resuscitation metric summaries (median [interquartile range]) by age: less than 1 year (38/112): chest compression fraction 0.88 (0.61-0.98), chest compression rate 119/min (110-129), and chest compression depth 2.3 cm (1.9-3.0 cm); for 1 to less than 8 years (42/112): chest compression fraction 0.94 (0.79-1.00), chest compression rate 117/min (110-124), and chest compression depth 3.8 cm (2.9-4.6 cm); for 8 to less than 18 years (32/112): chest compression fraction 0.94 (0.85-1.00), chest compression rate 117/min (110-123), chest compression depth 5.5 cm (4.0-6.5 cm). "Compliance" with guideline targets for 60-second chest compression "epochs" was predefined: chest compression fraction greater than 0.80, chest compression rate 100-120/min, and chest compression depth: greater than or equal to 3.4 cm in less than 1 year, greater than or equal to 4.4 cm in 1 to less than 8 years, and 4.5 to less than 6.6 cm in 8 to less than 18 years. Proportion of less than 1 year, 1 to less than 8 years, and 8 to less than 18 years events with greater than or equal to 60% of 60-second epochs meeting compliance (respectively): chest compression fraction was 53%, 81%, and 78%; chest compression rate was 32%, 50%, and 63%; chest compression depth was 13%, 19%, and 44%. For all events combined, total compliance (meeting all three guideline targets) was 10% (11/112). Across an international pediatric resuscitation collaborative, we characterized the landscape of pediatric in-hospital cardiac arrest chest compression quality metrics and found that they often do not meet 2015 American Heart Association guidelines. Guideline compliance for rate and depth in children less than 18 years is poor, with the greatest difficulty in achieving chest compression depth targets in younger children.

Stripping of chest tubes to promote drainage of the thorax of postthoracotomy patients has been routine practice, based on tradition. Recent published findings indicate that significant negative pressures are generated in the tube during stripping that could cause pain, bleeding and possible damage to the patient's lung tissue. To determine whether pediatric oncology patients whose chest tubes were not stripped would differ in frequency of pain, fever or lung complications from patients who underwent routine tube stripping. Data were collected at multiple points during the first 72-hour postoperative period from 16 patients assigned to the stripped or unstripped groups. Pain was measured by the Faces Pain Scale and the Visual Analogue Scale; temperature, by electronic thermometer; and lung complications, by stethoscope and radiographs. Both groups, which were comparable for age, primary diagnosis and prior history of lung problems, received identical supportive nursing and medical care, with the physicians blind to group assignment. The two groups did not differ significantly in frequency of pain, incidence of fever, breath sounds or radiographic findings across measurement points. A strong correlation was found between the pain scores using the two instruments. Patients whose tubes were not stripped did not have an increased risk of infection or lung complications. Study findings indicated that stripping did not increase the frequency of pain. Stripping of chest tubes as a routine postoperative measure is questioned.

To assess children with myocarditis, the frequency of various presenting symptoms, and the accuracy of different investigations in the diagnosis. This was an observational study of 63 patients admitted to PICU with non-cardiac diagnosis. Cardiac enzymes, chest-X ray, echocardiography, and electrocardiogram were performed to diagnose myocarditis among those patients. There were 16 cases of definite myocarditis. The age distribution was non-normal, with median of 5.5 months (3.25-21). Of the 16 patients who were diagnosed with myocarditis, 62.5% were originally diagnosed as having respiratory problems, and there were more females than males. Among the present cases, the accuracy of cardiac enzymes (cardiac troponin T [cTn] and creatine phosphokinase MB [CKMB]) in the diagnosis of myocarditis was only 63.5%, while the accuracy of low fractional shortening and of chest-X ray cardiomegaly was 85.7 and 80.9%; respectively. Cardiac troponin folds 2.02 had positive predictive value of 100%, negative predictive value of 88.7%, specificity of 100%, sensitivity of 62.5%, and accuracy of 90.5%. Children with myocarditis present with symptoms that can be mistaken for other types of illnesses. When clinical suspicion of myocarditis exists, chest-X ray and echocardiography are sufficient as screening tests. Cardiac troponins confirm the diagnosis in screened cases, with specificity of 100%.

2016-01-01

Background The 2010 neonatal resuscitation program (NRP) guidelines incorporate ventilation corrective steps (using the mnemonic – MRSOPA) into the resuscitation algorithm. The perception of neonatal providers, time taken to perform these maneuvers or the effectiveness of these additional steps has not been evaluated. Methods Using two simulated clinical scenarios of varying degrees of cardiovascular compromise –perinatal asphyxia with (i) bradycardia (heart rate – 40 min−1) and (ii) cardiac arrest, 35 NRP certified providers were evaluated for preference to performing these corrective measures, the time taken for performing these steps and time to onset of chest compressions. Results The average time taken to perform ventilation corrective steps (MRSOPA) was 48.9 ± 21.4 s. Providers were less likely to perform corrective steps and proceed directly to endotracheal intubation in the scenario of cardiac arrest as compared to a state of bradycardia. Cardiac compressions were initiated significantly sooner in the scenario of cardiac arrest 89 ± 24 s as compared to severe bradycardia 122 ± 23 s, p < 0.0001. There were no differences in the time taken to initiation of chest compressions between physicians or mid-level care providers or with the level of experience of the provider. Conclusions Effective ventilation of the lungs with corrective steps using a mask is important in most cases of neonatal resuscitation. Neonatal resuscitators prefer early endotracheal intubation and initiation of chest compressions in the presence of asystolic cardiac arrest. Corrective ventilation steps can potentially postpone initiation of chest compressions and may delay return of spontaneous circulation in the presence of severe cardiovascular compromise.

A 32-year-old, fit and healthy, Caucasian male presented with a less than 24-hour history of palpitations with the onset following participation in helicopter underwater escape training (HUET). He reported no chest pain, shortness of breath, syncope, or pre-syncope symptoms. On examination, an irregularly irregular pulse was noted at a rate of 120 beats per minute with a blood pressure of 132/84. There was no evidence of congestive cardiac failure. The electrocardiogram (ECG) demonstrated atrial fibrillation at 97 beats per minute with a normal axis, normal QRS complexes, and a QTc of 399 ms. Bloods were all within normal limits and a chest x-ray showed no abnormality. The patient was loaded with amiodarone and reverted to sinus rhythm with a normal post-reversion ECG. Five years on, following further HUET, the patient presented with an identical presentation. His ECG showed fast atrial fibrillation at a rate of 115 beats per minute. On this occasion, he was sedated and Direct Current cardioverted with reversal to sinus rhythm after one shock. It was felt that the precipitating factor for this patient's atrial fibrillation, in both cases, was HUET. The case discussed describes a previously fit and well subject who developed a sustained arrhythmia secondary to cold water submersion. Evidence suggests water submersion can provoke cardiac arrhythmias via the suggested theory of "autonomic conflict." It has been proposed that a number of unexplained deaths related to water submersion may be secondary to arrhythmogenic syncope.

Open chest cardiac massage (OCCM) is a commonly performed procedure after traumatic cardiac arrest (TCA). OCCM has been reported to be superior to closed chest compressions (CCC) in animal models and in non-TCA. The purpose of this study is to prospectively compare OCCM versus CCC in TCA using end-tidal carbon dioxide (ETCO2), the criterion standard for determining the effectiveness of chest compressions and detection of return of spontaneous circulation (ROSC), as the surrogate for cardiac output and marker for adequacy of resuscitation. This prospective observational study enrolled patients over a 9-month period directly presenting to a level 1 trauma center after TCA. Continuous high-resolution ETCO2 measurements were collected every 6 seconds for periods of CCC and OCCM, respectively. Patients receiving CCC only were compared with patients receiving CCC followed by OCCM. Student's t tests were used to compare ETCO2 within and between groups. Thirty-three patients were enrolled (16 OCCM, 17 CCC-only). Mean time of CCC before OCCM was 66 seconds. Within the OCCM group, final, peak, mean, and median ETCO2 levels significantly increased when comparing the initial CCC period to the OCCM interval. Using a time-matched comparison, significant increases were observed in the final and peak but not mean and median values when comparing the first minute of CCC to the remaining time in the CCC-only group. However, when periods of OCCM were compared with equivalent periods of CCC-only, there were no differences in the initial, final, peak, mean, or median ETCO2 values. Correspondingly, no difference in rates of ROSC was observed between groups (OCCM 23.5% vs. CCC 38.9%; p = 0.53). Although we could not control for confounders, we found no significant improvement in ETCO2 or ROSC with OCCM. With newer endovascular techniques for aortic occlusion, thoracotomy solely for performing OCCM provides no benefit over CCC. Therapeutic study, level III.

Acute chest syndrome is a major cause of death and hospitalisation in children with sickle cell anaemia. It is often initiated by an infection, particularly pneumonia. Microbial agents previously not associated with acute chest syndrome are becoming increasingly important. Group A beta-haemolytic Streptococcus (GABHS) is thought to be an uncommon cause of pneumonia in children with sickle cell anaemia. We report a 15-year-old African-American girl who presented with an acute chest event characterised by fever, cough, chest pain, shortness of breath, right upper abdominal quadrant pain, jaundice and otitis media. Chest radiograph showed multi-lobar pneumonia with left pleural effusion. Group A beta-haemolytic Streptococcus was isolated from culture of pleural and middle ear fluids. She responded to therapy that included antibiotics, exchange blood transfusion, oxygen, thoracotomy chest tube drainage and decortication. In a child with sickle cell anaemia presenting with fever and an acute chest event, pneumonia should be considered and GABHS recognised as a possible aetiological agent. In addition, a chest X-ray should be obtained and antibiotics against agents causing community-acquired pneumonia instituted.

Cardiac trauma is a leading cause of death in the United States and occurs mostly due to motor vehicle accidents. Blunt cardiac trauma and penetrating chest injuries are most common, and both can lead to aortic injuries. Timely diagnosis and early management are the key to improve mortality. Cardiac computed tomography and cardiac ultrasound are the 2 most important diagnostic modalities. Mortality related to cardiac trauma remains high despite improvement in diagnosis and management.

Myocardial involvement in rocky mountain spotted fever: a case report and review.

Rocky Mountain Spotted Fever (RMSF), caused by Rickettia rickettsii, is a serious tickborne illness that is endemic in the southeastern United States. Although it is most commonly known as a cause of fever and rash, it can have systemic manifestations. The myocardium may rarely be involved, with symptoms that can mimic those of acute coronary syndromes. This report describes a case of serologically proven RMSF causing symptomatic myocarditis, manifested by chest pain, elevated cardiac enzyme levels, and decrease myocardial function. After treatment with antibiotics, the myocarditis resolved. Thus, although unusual, the clinician should be aware of myocardial disease in patients with appropriate exposure histories or other clinical signs of RMSF. Close monitoring and an aggressive approach are essential to reduce mortality rates.

It revealed no discernible ST-T changes but unmasked a J wave at the end of the QRS complex, which was associated with short-coupled repetitive premature ventricular beats. A J wave reportedly appears immediately before the onset of ventricular fibrillation caused by vasospastic angina. However, a J wave observed newly after a coronary spasm provocation test using ACh without ST-T changes is informative when considering the mechanisms of the J wave.

Double hazards of ischemia and reperfusion arrhythmias in a patient with variant angina pectoris.

Variant angina pectoris, also called Prinzmetal's angina, is a syndrome caused by vasospasms of the coronary arteries. It can lead to myocardial infarction, ventricular arrhythmias, atrioventricular block and even sudden cardiac death. We report the case of a 53 year-old male patient with recurrent episodes of chest pain and arrhythmias in the course of related variant angina pectoris. It is likely that the reperfusion following myocardial ischemia was responsible for the ventricular fibrillation while the ST-segment returned to the baseline. This case showed that potential lethal arrhythmias could arise due to variant angina pectoris. It also indicated that ventricular fibrillation could be self-terminated. Copyright © 2015 Elsevier Inc.

Sinus of Valsalva aneurysm is a rare condition and associated with a high rate of mortality if rupture occurs. The aneurysms are rarely diagnosed until rupture occurs. This case describes a young Native American female whose only symptom was intermittent chest pain prior to the detection of the aneurysm along with a small ventricular septal defect. The patient was also found to have a coexisting coronary artery fistula, and it is rare phenomenon to have these coexisting anomalies. The anomalies were demonstrated on both cardiac computed tomography and coronary angiography. The patient underwent surgical closure of both anomalies, which is the recommended treatment to avoid future complications. PMID:24804114

Accelerated junctional rhythm has been reported in children in the setting of acute rheumatic fever; however, we describe a hitherto unreported case of isolated junctional tachycardia in a child with streptococcal pharyngitis, not meeting revised Jones criteria for rheumatic fever. A previously healthy, 9-year-old girl presented to the emergency department with complaints of sore throat, low-grade fever, and intermittent chest pain. She was found to have a positive rapid streptococcal antigen test. The initial electrocardiogram showed junctional tachycardia with atrioventricular dissociation in addition to prolonged and aberrant atrioventricular conduction. An echocardiogram revealed normal cardiac anatomy with normal biventricular function. The patient responded to treatment with amoxicillin for streptococcal pharyngitis. The junctional tachycardia and other electrocardiogram abnormalities resolved during follow-up.

Wellens' syndrome and other electrocardiographic changes in a patient with a left anterior descending artery subocclusion associated with a left main coronary artery subocclusion.

Changing axis deviation has been reported also during atrial fibrillation or atrial flutter. Changing axis deviation has been also reported during acute myocardial infarction associated with atrial fibrillation too or at the end of atrial fibrillation during acute myocardial infarction. Patients with unstable angina have a higher incidence of left main coronary artery (LMCA) and proximal left anterior descending (LAD) coronary artery disease compared to patients with stable angina pectoris. In 1982, Wellens and colleagues described two electrocardiographic patterns that were predictive of critical narrowing of the proximal LAD artery, and were subsequently termed Wellens' syndrome. The criteria were: a) prior history of chest pain, b) little or no cardiac enzyme elevation, c) no pathologic precordial ST segment elevation, d) no loss of precordial R waves, and e) biphasic T waves in leads V2 and V3, or asymmetric, often deeply inverted T waves in leads V2 and V3. The ECG changes are best recognized outside the episode of anginal pain. Lead aVR and lead v1 ST segment elevation, during chest pain, has been reported in patients with LMCA disease with ST segment depression in leads V3, V4 and V5 (with maximal depression in V4).We present a case of changing axis deviation in a 37-year-old Italian man with a LAD coronary artery subocclusion associated with a LMCA subocclusion. This case focuses attention on the importance of the recognition of the patterns suspected for LAD coronary artery disease or for LMCA disease. Copyright © 2009 Elsevier Ireland Ltd.

Jacob, Eufemia; Sockrider, Marianna M; Dinu, Marlen; Acosta, Monica; Mueller, Brigitta U

2010-01-01

The authors examined the prevalence of respiratory symptoms and determined whether respiratory symptoms were associated with prevalence of chest pain and number of acute painful episodes in children and adolescents with sickle cell disease. Participants (N = 93; 44 females, 49 males; mean age 9.8 +/- 4.3 years) reported coughing in the morning (21.5%), at night (31.2%), and during exercise (30.1%). Wheezing occurred both when they had a cold or infection (29.0%) and when they did not have (23.7%) a cold or infection. Sleep was disturbed by wheezing in 20.4%. Among the 76 patients who were school-age (>5 years), 19.7% of patients missed more than 4 days of school because of respiratory symptoms. The majority of patients reported having acute painful episodes (82.8%), and most (66.7%) reported having chest pain during acute painful episodes in the previous 12 months. Participants with acute pain episodes greater than 3 during the previous 12 months had significantly higher reports of breathing difficulties (P = .01) and chest pain (P = .002). The high number of respiratory symptoms (cough and wheeze) among patients with sickle cell disease may trigger acute painful episodes. Early screening and recognition, ongoing monitoring, and proactive management of respiratory symptoms may minimize the number of acute painful episodes.

Background: The correlation between normal cardiac chamber linear dimensions measured during retrospective coronary computed tomographic angiography as compared to transthoracic echocardiography using the American Society of Echocardiography guidelines is not well established. Methods: We performed a review from January 2005 to July 2011 to identify subjects with retrospective electrocardiogram-gated coronary computed tomographic angiography scans for chest pain and transthoracic echocardiography with normal cardiac structures performed within 90 days. Dimensions were manually calculated in both imaging modalities in accordance with the American Society of Echocardiography published guidelines. Left ventricular ejection fraction was calculated on echocardiography manually using the Simpson’s formula and by coronary computed tomographic angiography using the end-systolic and end-diastolic volumes. Results: We reviewed 532 studies, rejected 412 and had 120 cases for review with a median time between studies of 7 days (interquartile range (IQR25,75) = 0–22 days) with no correlation between the measurements made by coronary computed tomographic angiography and transthoracic echocardiography using Bland–Altman analysis. We generated coronary computed tomographic angiography cardiac dimension reference ranges for both genders for our population. Conclusion: Our findings represent a step towards generating cardiac chamber dimensions’ reference ranges for coronary computed tomographic angiography as compared to transthoracic echocardiography in patients with normal cardiac morphology and function using the American Society of Echocardiography guideline measurements that are commonly used by cardiologists.

Chest pain emergency centers: improving acute myocardial infarction care.

PubMed

Ornato, J P

1999-08-01

Uncertainty and delay are common in the diagnosis of acute coronary syndromes (ACS). In the last 20 years, the need for faster, more accurate, and more cost-effective diagnosis gave rise to the concept of specialized treatment of patients with chest pain in emergency departments (EDs). The original strategy dedicated a separate section of the ED and a nursing staff to the task of rapid intervention in patients with acute myocardial infarction (MI) and triage of low-risk patients. Chest pain centers grew quickly in popularity but evolved with a variety of goals, staffing plans, diagnostic resources, and levels of commitment. There existing centers--the University of Cincinnati Heart ER, Brigham and Women's Hospital, and the Medical College of Virginia--have implemented chest pain strategies with the common aims of (1) screening for the entire spectrum of coronary artery disease, (2) avoiding unnecessary admissions, and (3) using multiple diagnostic modalities. Yet, they differ in the specifics of their approaches and diagnostic methods (e.g., echocardiography vs. treadmill vs. myocardial perfusion imaging). The safety and cost effectiveness of these centers are discussed.

Oxygen (O 2 ) have been a cornerstone in the treatment of acute myocardial infarction. Studies have been inconclusive regarding the cardiovascular and analgesic effects of oxygen in these patients. In the SOCCER trial, we compared the effects of oxygen treatment versus room air in patients with ST-elevation myocardial infarction (STEMI). There was no difference in myocardial salvage index or infarct size assessed with cardiac magnetic resonance imaging. In the present subanalysis, we wanted to evaluate the effect of O 2 on chest pain in patients with STEMI. Normoxic patients with first time STEMI were randomized in the ambulance to standard care with 10 l/min O 2 or room air until the end of the percutaneous coronary intervention (PCI). The ambulance personnel noted the patients´ chest pain on a visual analog scale (VAS; 1-10) before randomization and after the transport but before the start of the PCI, and also registered the amount of morphine given. 160 patients were randomized to O 2 (n = 85) or room air (n = 75). The O 2 group had a higher median VAS at randomization than the air group (7.0 ± 2.3 vs 6.0 ± 2.9; p = .02) and also received a higher median total dose of morphine (5.0 mg ± 4.4 vs 4.0 mg ± 3.7; p = .02). There was no difference between the O 2 and air groups in VAS at the start of the PCI (4.0 ± 2.4 vs 3.0 ± 2.5; p = .05) or in the median VAS decrease from randomization to the start of the PCI (-2.0 ± 2.2 vs -1.0 ± 2.9; p = .18). Taken together with previously published data, these results do not support a significant analgesic effect of oxygen in patients with STEMI.

To establish the reference value of high sensitive cardiac troponin T (hs-cTnT) and the efficiency of reference value in the diagnosis of chest pain. Volunteers from eight independent communities in Chengdu,Sichuan were selected with detailed records of physical examination,electrocardiogram,ultrasound examination. The level of hs-cTnT for healthy volunteers was tested to determine ninety-ninth percentile references according to sex and ages. 2 249 patients with chest pain in the emergency department of Western China Hospital from July 2009 to July 2014 were enrolled to measure the efficiency of reference value for diagnosing acute myocardial infarction (AMI). There were 1 305 volunteers included finally. Among them,the mean hs-cTnT level of male was 4.3 (3.2-5.9) ng/L,which was significantly higher than that of female 3.0 (3.0-3.1) ng/L ( P <0.01) . The correlation coefficient between age and hs-cTnT level was 0.43 (male) and 0.29 (female),and the P -value was less than 0.01. The 99th percentile values of male were 10.8 ng/L,15.4 ng/L and 19.7 ng/L for <45 yr.,45-<60 yr. and ≥60 yr.,respectively. Those values of female were 4.6 ng/L,8.9 ng/L,18.8 ng/L,respectively. There was no difference in sensitivity and specificity between the value we figured out and manufactures provided (14.0 ng/L) for those<60 yr.. For the patients ≥60 yr.,the sensitivity and negative predictive value did not show diversity ( P >0.05) but the specificity and positive predictive value showed significant difference (male: 0.67 vs. 0.56 and 0.83 vs. 0.79, P <0.05;female:0.75 vs. 0.68 and 0.74 vs. 0.69, P <0.05). We recommends that the ninety-ninth percentile reference value of patients<60 yr. should be 14.0 ng/L,while 20.0 ng/L for those patients≥60 yr.

Typical angina pectoris (AP) and high-sensitive troponin I (hs-TnI) are independently associated with coronary artery disease (CAD) and future cardiovascular events (CVE). This study aimed to assess the individual and combined diagnostic and prognostic impact of symptoms and hs-TnI in stable chest pain patients without prior cardiovascular disease. During a one-year period, 487 patients with suspected stable AP underwent invasive or CT-coronary angiography (significant stenosis ≥50%). At study inclusion, a careful symptom evaluation was obtained, and patients were classified as having typical AP, atypical AP, or non-cardiac chest pain. Hs-TnI was measured in all patients and divided into tertiles for analysis. Follow-up was a median of 4.9 years with cardiovascular death, non-fatal myocardial infarction, unstable AP, ischemic stroke, coronary-artery-bypass-grafting, percutaneous coronary intervention, and peripheral vascular surgery as combined endpoint. Hs-TnI was detected in 486 patients (99.8%). By multivariate regression analysis, typical AP and hs-TnI elevation were associated with increased risk of having significant CAD (typical AP, OR: 3.46; 95% CI: 2.07-5.79; p < 0.0001, hs-TnI, OR: 1.50; 95% CI: 1.12-2.01; p = 0.007) and experiencing future CVE (typical AP, HR: 2.64; 95% CI: 1.74-3.99; p = 0.001, hs-TnI, HR: 1.26; 95% CI: 1.06-1.49; p = 0.008). Patients in the lowest hs-TnI tertile, without typical AP (n = 107) had a 1.9% absolute risk of significant CAD and a 3.7% absolute risk of long-term CVE. In clinical stable patients without known cardiovascular disease, a thorough chest-pain history in combination with hs-TnI testing can identify a significant low-risk group. The prognostic need for coronary angiography in these patients seems limited. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Cystic echinococcosis (CE) can affect the heart and the vena cava but few cases are reported. A retrospective case series of 11 patients with cardiac and/or endovascular CE, followed-up over a period of 15 years (1995-2009) is reported. Main clinical manifestations included thoracic pain or dyspnea, although 2 patients were asymptomatic. Cysts were located mostly in the right atrium and inferior vena cava. Nine patients were previously diagnosed with disseminated CE. Echocardiography was the diagnostic method of choice, although serology, electrocardiogram, chest X-ray, computed tomography/magnetic resonance imaging and histology aided with diagnosis and follow-up. Nine patients underwent cardiac surgery and nine received long-term antiparasitic treatment for a median duration of 25 months (range 4-93 months). One patient died intra-operatively due to cyst rupture and endovascular dissemination. Two patients died 10 and 14 years after diagnosis, due to pulmonary embolism (PE) and cardiac failure, respectively. One patient was lost to follow-up. Patients who had cardiac involvement exclusively did not have complications after surgery and were considered cured. There was only one recurrence requiring a second operation. Patients with vena cava involvement developed PEs and presented multiple complications. Cardiovascular CE is associated with a high risk of potentially lethal complications. Clinical manifestations and complications vary according to cyst location. Isolated cardiac CE may be cured after surgery, while endovascular extracardiac involvement is associated with severe chronic complications. CE should be included in the differential diagnosis of cardiovascular disease in patients from endemic areas. © 2012 Díaz-Menéndez et al.

Background Cardiovascular urgencies are frequent reasons for seeking medical care. Prompt and accurate medical diagnosis is critical to reduce the morbidity and mortality of these conditions. Objective To evaluate the use of a pocket-size echocardiography in addition to clinical history and physical exam in a tertiary medical emergency care. Methods One hundred adult patients without known cardiac or lung diseases who sought emergency care with cardiac complaints were included. Patients with ischemic changes in the electrocardiography or fever were excluded. A focused echocardiography with GE Vscan equipment was performed after the initial evaluation in the emergency room. Cardiac chambers dimensions, left and right ventricular systolic function, intracardiac flows with color, pericardium, and aorta were evaluated. Results The mean age was 61 ± 17 years old. The patient complaint was chest pain in 51 patients, dyspnea in 32 patients, arrhythmia to evaluate the left ventricular function in ten patients, hypotension/dizziness in five patients and edema in one patient. In 28 patients, the focused echocardiography allowed to confirm the initial diagnosis: 19 patients with heart failure, five with acute coronary syndrome, two with pulmonary embolism and two patients with cardiac tamponade. In 17 patients, the echocardiography changed the diagnosis: ten with suspicious of heart failure, two with pulmonary embolism suspicious, two with hypotension without cause, one suspicious of acute coronary syndrome, one of cardiac tamponade and one of aortic dissection. Conclusion The focused echocardiography with pocket-size equipment in the emergency care may allow a prompt diagnosis and, consequently, an earlier initiation of the therapy. PMID:25590933

American Indian Women and Cardiovascular Disease

Cardiovascular disease (CVD) is currently the number one killer of American women. Consequently, CVD is a concern for all women, including ethnic women. However, little is known about CVD behaviors and responses to CVD symptomology among minority women, especially American Indian women. Response behaviors to chest pain require important actions. This article examines response behaviors to chest pain in a group of American Indian women participants of the Inter-Tribal Heart Project. In 1992 to 1994, 866 American Indian women, aged 22 years and older, participated in face-to-face interviews to answer survey questions on multiple areas related to cardiovascular disease on 3 rural reservations in Minnesota and Wisconsin. A secondary data analysis was conducted on selected variables including demographic characteristics, healthcare access, rating of health status, personal and family history of cardiovascular disease, and action in response to crushing chest pain that lasted longer than 15 minutes. Research findings report that 68% of women would actively seek healthcare immediately if experiencing crushing chest pain that lasted longer than 15 minutes. However, 264 women (32%) would take a passive action to crushing chest pain, with 23% reporting they would sit down and wait until it passed. Analysis revealed women reporting a passive response were younger in age (under age 45) and had less education (less than a high school education). These findings have implications for nurses and other healthcare providers working in rural, geographically isolated Indian reservations. How to present CVD education in a culturally appropriate manner remains a challenge. PMID:15191257

Emergency medical care requirements for large public assemblies and a new strategy for managing cardiac arrest in this setting.

Weaver, W D; Sutherland, K; Wirkus, M J; Bachman, R

1989-02-01

During the 1986 World's Exposition held in Vancouver, British Columbia, the types and frequencies of emergency medical problems were assessed. The average number of patients seeking care was 3.93 +/- 0.95 per 1,000 visitors (daily range, 1.94 to 6.8). Patient loads were linearly related to gate attendance, but the correlation was imperfect (P less than .001, r = .63). Only 4.4% of patients evaluated on site by nurses and paramedics were referred for additional testing and treatment: of these patients, 30% had suspected serious musculoskeletal injury, 16% had abdominal pain, and 25% had complaints of chest pain, dizziness, or loss of consciousness. Lay employees (security personnel) were trained to use automatic external defibrillators. There were six cardiac arrests (0.3 per million visitors). Two patients collapsed with ventricular fibrillation, were defibrillated by lay personnel, quickly regained consciousness, and survived. The other arrests were associated with asystole or electromechanical dissociation; no shocks were inappropriately given, and all four died. We conclude that four of every 1,000 persons at this assembly sought emergency medical care, that 95% of the problems seen were minor with few requiring physician skills, and that the automatic external defibrillator was suited for this setting and could be used by lay responders to provide early definitive treatment.

An 80 years old man suffered a cardiac arrest shortly after arrival to his local health department. Basic Life Support was started promptly and nine minutes later, on evaluation by an Advanced Life Support team, the victim was defibrillated with a 200J shock. When orotracheal intubation was attempted, masseter muscle contraction was noticed: on reevaluation, the victim had pulse and spontaneous breathing.Thirty minutes later, the patient had been transferred to an emergency department. As he complained of chest pain, the ECG showed a ST segment depression in leads V4 to V6 and laboratory tests showed cardiac troponine I slightly elevated. A coronary angiography was performed urgently: significant left main plus three vessel coronary artery disease was disclosed.Eighteen hours after the cardiac arrest, a quadruple coronary artery bypass grafting operation was undertaken. During surgery, a fresh thrombus was removed from the middle left anterior descendent artery. Post-operative course was uneventful and the patient was discharged seven days after the procedure. Twenty four months later, he remains asymptomatic.In this case, the immediate call for the Advanced Life Support team, prompt basic life support and the successful defibrillation, altogether, contributed for the full recovery. Furthermore, the swiftness in the detection and treatment of the acute reversible cause (myocardial ischemia in this case) was crucial for long-term prognosis.

Objective: Quantitation of D-dimer level during a sickling crisis and its correlation with other clinical abnormalities. Design: Prospective longitudinal study. Setting: Armed Forces Hospital, Southern Region, Kingdom of Saudi Arabia. Patients: Adult patients (12 years and older) admitted acutely with a sickle cell crisis who consent to taking part in the study. Candidates may re-participate if they are readmitted with a further acute painful crisis. Results: 36 patients with homozygous sickle cell disease consented to take part in the study. D-dimer levels were raised in 31 (68.9%) of 45 episodes of painful crisis of whom 13 had an abnormal chest X-ray. Of those with a normal chest X-ray only one patient had a raised D-dimer level: sensitivity of 92.3%, specificity 40.6%, positive predictive value 38.7% and negative predictive value of 92.9% for an abnormal chest X-ray. Conclusion: D-dimer levels are frequently raised during an acute painful crisis. A normal level has a high negative predictive value for an abnormal chest X-ray. PMID:21063468

Noonan syndrome is an autosomal dominant, multisystem disorder. Autoimmune thyroiditis with hypothyroidism is an infrequent feature in patients with Noonan syndrome. A 16-year-old boy was admitted because of chest discomfort and dyspnea; an echocardiogram revealed pericardial effusion. Additional investigations led to a diagnosis of severe hypothyroidism due to Hashimoto thyroiditis. The patient was treated with L-thyroxine at 0.15 mg daily. However, during admission, he developed symptoms of cardiac tamponade. Closed pericardiostomy was performed, after which the patient's chest discomfort improved, and his vital signs stabilized. Herein, we report a case of an adolescent with Noonan syndrome, who was diagnosed with Hashimoto thyroiditis with an unusual presentation of cardiac tamponade.

Comparison of Chest Pain Protocols for Electrocardiography-Gated Dual-Source Cardiothoracic CT in Children and Adults: The Effect of Tube Current Saturation on Radiation Dose Reduction

PubMed Central

2018-01-01

Objective To compare radiation doses between conventional and chest pain protocols using dual-source retrospectively electrocardiography (ECG)-gated cardiothoracic computed tomography (CT) in children and adults and assess the effect of tube current saturation on radiation dose reduction. Materials and Methods This study included 104 patients (16.6 ± 7.7 years, range 5–48 years) that were divided into two groups: those with and those without tube current saturation. The estimated radiation doses of retrospectively ECG-gated spiral cardiothoracic CT were compared between conventional, uniphasic, and biphasic chest pain protocols acquired with the same imaging parameters in the same patients by using paired t tests. Dose reduction percentages, patient ages, volume CT dose index values, and tube current time products per rotation were compared between the two groups by using unpaired t tests. A p value < 0.05 was considered significant. Results The volume CT dose index values of the biphasic chest pain protocol (10.8 ± 3.9 mGy) were significantly lower than those of the conventional protocol (12.2 ± 4.7 mGy, p < 0.001) and those of the uniphasic chest pain protocol (12.9 ± 4.9 mGy, p < 0.001). The dose-saving effect of biphasic chest pain protocol was significantly less with a saturated tube current (4.5 ± 10.2%) than with unsaturated tube current method (14.8 ± 11.5%, p < 0.001). In 76 patients using 100 kVp, patient age showed no significant differences between the groups with and without tube current saturation in all protocols (p > 0.05); the groups with tube current saturation showed significantly higher volume CT dose index values (p < 0.01) and tube current time product per rotation (p < 0.001) than the groups without tube current saturation in all protocols. Conclusion The radiation dose of dual-source retrospectively ECG-gated spiral cardiothoracic CT can be reduced by approximately 15% by using the biphasic chest pain protocol instead of the conventional protocol in children and adults if radiation dose parameters are further optimized to avoid tube current saturation.

Guidelines for cardiopulmonary resuscitation recommend a chest compression rate of at least 100 compressions/min. A recent clinical study reported optimal return of spontaneous circulation with rates between 100 and 120/min during cardiopulmonary resuscitation for out-of-hospital cardiac arrest. However, the relationship between compression rate and survival is still undetermined. Prospective, observational study. Data is from the Resuscitation Outcomes Consortium Prehospital Resuscitation IMpedance threshold device and Early versus Delayed analysis clinical trial. Adults with out-of-hospital cardiac arrest treated by emergency medical service providers. None. Data were abstracted from monitor-defibrillator recordings for the first five minutes of emergency medical service cardiopulmonary resuscitation. Multiple logistic regression assessed odds ratio for survival by compression rate categories (<80, 80-99, 100-119, 120-139, ≥140), both unadjusted and adjusted for sex, age, witnessed status, attempted bystander cardiopulmonary resuscitation, location of arrest, chest compression fraction and depth, first rhythm, and study site. Compression rate data were available for 10,371 patients; 6,399 also had chest compression fraction and depth data. Age (mean±SD) was 67±16 years. Chest compression rate was 111±19 per minute, compression fraction was 0.70±0.17, and compression depth was 42±12 mm. Circulation was restored in 34%; 9% survived to hospital discharge. After adjustment for covariates without chest compression depth and fraction (n=10,371), a global test found no significant relationship between compression rate and survival (p=0.19). However, after adjustment for covariates including chest compression depth and fraction (n=6,399), the global test found a significant relationship between compression rate and survival (p=0.02), with the reference group (100-119 compressions/min) having the greatest likelihood for survival. After adjustment for chest compression fraction and depth, compression rates between 100 and 120 per minute were associated with greatest survival to hospital discharge.

Costovertebral joint dysfunction: another misdiagnosed cause of atypical chest pain.

Arroyo, J. F.; Jolliet, P.; Junod, A. F.

1992-01-01

The diagnostic work-up of atypical chest pain frequently leads to invasive procedures. However, this painful symptomatology can sometimes be of benign origin and respond to simple therapeutic manoeuvres. A number of musculoskeletal conditions such as costovertebral joint dysfunctions should be carefully considered. We report five cases in which patient discomfort and high costs could have been avoided if awareness of these conditions had led to a correct diagnosis upon initial physical examination.

We developed a method of closed-chest cardiopulmonary bypass to arrest and protect the heart with cardioplegic solution. This method was used in 54 dogs and the results were retrospectively analyzed. Bypass cannulas were placed in the right femoral vessels. A balloon occlusion catheter was passed via the left femoral artery and positioned in the ascending aorta. A pulmonary artery vent was placed via the jugular vein. In 17 of the dogs retrograde cardioplegia was provided with a percutaneous coronary sinus catheter. Cardiopulmonary bypass time was 111 +/- 27 minutes (mean +/- standard deviation) and cardiac arrest time was 66 +/- 21 minutes. Preoperative cardiac outputs were 2.9 +/- 0.70 L/min and postoperative outputs were 2.9 +/- 0.65 L/min (p = not significant). Twenty-one-French and 23F femoral arterial cannulas that allowed coaxial placement of the ascending aortic balloon catheter were tested in 3 male calves. Line pressures were higher, but not clinically limiting, with the balloon catheter placed coaxially. Adequate cardiopulmonary bypass and cardioplegia can be achieved in the dog without opening the chest, facilitating less invasive cardiac operations. A human clinical trial is in progress.

Managing acute coronary syndrome during medical air evacuation from a remote location at sea.

PubMed

Westmoreland, Andrew H

2014-01-01

Coronary emergencies at sea requiring air evacuation are not uncommon. On board a Nimitz-class aircraft carrier while in a remote location, an active duty sailor suffered a myocardial infarction. A medical evacuation by helicopter was necessary. Transfer proved difficult due to the ship's location, poor flying conditions, and the patient's deteriorating condition. This case stresses the importance of expeditious diagnosis, treatment, and air transfer to shore-based facilities capable of providing definitive coronary care. A 33-yr-old man recently started on trazodone due to depression complained of chest pain. The patient was hemodynamically unstable and electrocardiogram showed ST segment elevation and Q waves in the anterior, inferior, and lateral leads. He was air-lifted to the nearest accepting facility with cardiac catheterization capabilities, which was over 300 miles away. Poor weather conditions hindered the pilot's ability to fly the original course. The patient remained critical and medication choices were limited. Even with all of these obstacles, everyone involved performed his or her duties admirably. The patient's condition improved by the time the helicopter landed. He was then rushed by ambulance to the hospital's coronary care unit, where he was successfully treated. This case highlights the need to keep a high index of suspicion when patients complain of chest pain, regardless of age. It is of the utmost importance that individuals capable of thinking and acting quickly are assigned to medical evacuation teams, and that they continue to train regularly, as coronary events at sea are not uncommon.

The aim of the study was to determine if Sonoclot with its sensitive glass bead-activated, viscoelastic test can predict postoperative bleeding in patients undergoing cardiac surgery at predefined time points. A prospective, observational clinical study. A teaching hospital, single center. Consecutive patients undergoing cardiac surgery (N = 300). Besides routine laboratory coagulation studies and heparin management with standard (kaolin) activated clotting time, additional native blood samples were analyzed on a Sonoclot using glass bead-activated tests. Glass bead-activated clotting time, clot rate, and platelet function were recorded immediately before anesthesia induction and at the end of surgery after heparin reversal but before chest closure. Primary outcome was postoperative blood loss (chest tube drainage at 4, 8, and 12 hours postoperatively). Secondary outcome parameters were transfusion requirements, need for surgical re-exploration, time of mechanical ventilation, length of intensive care unit and hospital stay, and hospital morbidity and mortality. Patients were categorized into "bleeders" and "nonbleeders." Patient characteristics, operations, preoperative standard laboratory parameters, and procedural times were comparable between bleeders and nonbleeders except for sex and age. Bleeders had higher rates of transfusions, surgical re-explorations, and complications. Only glass bead measurements by Sonoclot after heparin reversal before chest closure but not preoperatively were predictive for increased postoperative bleeding. Sonoclot with its glass bead-activated tests may predict the risk for postoperative bleeding in patients undergoing cardiac surgery at the end of surgery after heparin reversal but before chest closure.

Fatal Small Intestinal Ischemia Due to Methamphetamine Intoxication: Report of a Case With Autopsy Results.

PubMed

Attaran, Hamid

2017-05-01

Methamphetamine is one of the most common abused drugs, so its various effects on different body organs should be familiar to all physicians. Regarding its gastrointestinal sequels, there are few reports of ischemic colitis induced by its vasoconstrictive effects. This is the first report of isolated small intestinal infarction resulting in death following methamphetamine toxicity. A 40-year-old woman with a past history of medical treatment for obesity referred to hospital with severe chest and back pain, perspiration, nausea, agitation, high blood pressure, bradycardia and subsequent lethargy and vasomotor instability. Cardiac evaluations were normal, and a toxicologic urinalysis revealed methamphetamine. Later, abdominal pain predominated, and ultrasonography revealed signs of bowel infarction. She did not consent to surgery and succumbed afterward. At autopsy gangrene and perforation of distal ileum were found. The cause of death was determined as intestinal gangrene following methamphetamine toxicity. Methamphetamine has anorectic effects and so is used in some "diet pills"; Consumers may not even know they are using methamphetamine. Hence in cases of either known MA abuse or those using unknown weight reduction drugs presenting with gastrointestinal complaints or abdominal pain, intestinal ischemia should be kept in mind and if plausible, intervened promptly.

Studies reporting the safety of magnetic resonance imaging (MRI) in patients with a cardiac implantable electronic device (CIED) have mostly excluded examinations with the device in the magnet isocenter. The purpose of this study was to describe the safety of cardiac and thoracic spine MRI in patients with a CIED. The medical records of patients with a CIED who underwent a cardiac or thoracic spine MRI between January 2011 and December 2014 were reviewed. Devices were interrogated before and after imaging with reprogramming to asynchronous pacing in pacemaker-dependent patients. The clinical interpretability of the MRI and peak and average specific absorption rates (SARs, W/kg) achieved were determined. Fifty-eight patients underwent 51 cardiac and 11 thoracic spine MRI exams. Twenty-nine patients had a pacemaker and 29 had an implantable cardioverter defibrillator. Seventeen percent (n = 10) were pacemaker dependent. Fifty-one patients (89%) had non-MRI-conditional devices. There were no clinically significant changes in atrial and ventricular sensing, impedance, and threshold measurements. There were no episodes of device mode changes, arrhythmias, therapies delivered, electrical reset, or battery depletion. One study was prematurely discontinued due to a patient complaint of chest pain of which the etiology was not determined. Across all examinations, the average peak SAR was 2.0 ± 0.85 W/kg with an average SAR of 0.35 ± 0.37 W/kg. Artifact significantly limiting the clinical interpretation of the study was present in 33% of cardiac MRI studies. When a comprehensive CIED magnetic resonance safety protocol is followed, the risk of performing 1.5-T magnetic resonance studies with the device in the magnet isocenter, including in patients who are pacemaker dependent, is low.

The HEART score for early rule out of acute coronary syndromes in the emergency department: a systematic review and meta-analysis.

PubMed

Van Den Berg, Patricia; Body, Richard

2018-03-01

The objective of this systematic review was to summarise the current evidence on the diagnostic accuracy of the HEART score for predicting major adverse cardiac events in patients presenting with undifferentiated chest pain to the emergency department. Two investigators independently searched Medline, Embase and Cochrane databases between 2008 and May 2016 identifying eligible studies providing diagnostic accuracy data on the HEART score for predicting major adverse cardiac events as the primary outcome. For the 12 studies meeting inclusion criteria, study characteristics and diagnostic accuracy measures were systematically extracted and study quality assessed using the QUADAS-2 tool. After quality assessment, nine studies including data from 11,217 patients were combined in the meta-analysis applying a generalised linear mixed model approach with random effects assumption (Stata 13.1). In total, 15.4% of patients (range 7.3-29.1%) developed major adverse cardiac events after a mean of 6 weeks' follow-up. Among patients categorised as 'low risk' and suitable for early discharge (HEART score 0-3), the pooled incidence of 'missed' major adverse cardiac events was 1.6%. The pooled sensitivity and specificity of the HEART score for predicting major adverse cardiac events were 96.7% (95% confidence interval (CI) 94.0-98.2%) and 47.0% (95% CI 41.0-53.5%), respectively. Patients with a HEART score of 0-3 are at low risk of incident major adverse cardiac events. As 3.3% of patients with major adverse cardiac events are 'missed' by the HEART score, clinicians must ask whether this risk is acceptably low for clinical implementation.

Rapid over-activation of β-adrenergic receptor (β-AR) upon stress leads to cardiac inflammation, a prevailing factor that underlies heart injury. However, mechanisms by which acute β-AR stimulation induce cardiac inflammation still remain unknown. Here, we set out to identify the crucial role of inflammasome/interleukin (IL)-18 in initiating and maintaining cardiac inflammatory cascades upon β-AR insult. Male C57BL/6 mice were injected with a single dose of β-AR agonist, isoproterenol (ISO, 5 mg/kg body weight) or saline subcutaneously. Cytokine array profiling demonstrated that chemokines dominated the initial cytokines upregulation specifically within the heart upon β-AR insult, which promoted early macrophage infiltration. Further investigation revealed that the rapid inflammasome-dependent activation of IL-18, but not IL-1β, was the critical up-stream regulator for elevated chemokine expression in the myocardium upon ISO induced β1-AR-ROS signalling. Indeed, a positive correlation was observed between the serum levels of norepinephrine and IL-18 in patients with chest pain. Genetic deletion of IL-18 or the up-stream inflammasome component NLRP3 significantly attenuated ISO-induced chemokine expression and macrophage infiltration. In addition, IL-18 neutralizing antibodies selectively abated ISO-induced chemokines, proinflammatory cytokines and adhesion molecules but not growth factors. Moreover, blocking IL-18 early after ISO treatment effectively attenuated cardiac inflammation and fibrosis. Inflammasome-dependent activation of IL-18 within the myocardium upon acute β-AR over-activation triggers cytokine cascades, macrophage infiltration and pathological cardiac remodelling. Blocking IL-18 at the early stage of β-AR insult can successfully prevent inflammatory responses and cardiac injuries. Published on behalf of the European Society of Cardiology.

Acute carbon monoxide poisoning has important clinical value because it can cause severe adverse cardiovascular effects and sudden death. Acute carbon monoxide poisoning due to charcoal is well reported worldwide, and increased use of charcoal in the restaurant industry raises concern for an increase in occupational health problems. We present a case of carbon monoxide poisoning induced cardiomyopathy in a 47-year-old restaurant worker. A male patient was brought to the emergency department to syncope and complained of left chest pain. Cardiac angiography and electrocardiography were performed to rule out acute ischemic heart disease, and cardiac markers were checked. After relief of the symptoms and stabilization of the cardiac markers, the patient was discharged without any complications. Electrocardiography was normal, but cardiac angiography showed up to a 40% midsegmental stenosis of the right coronary artery with thrombotic plaque. The level of cardiac markers was elevated at least 5 to 10 times higher than the normal value, and the carboxyhemoglobin concentration was 35% measured at one hour after syncope. Following the diagnosis of acute carbon monoxide poisoning induced cardiomyopathy, the patient's medical history and work exposure history were examined. He was found to have been exposed to burning charcoal constantly during his work hours. Severe exposure to carbon monoxide was evident in the patient because of high carboxyhemoglobin concentration and highly elevated cardiac enzymes. We concluded that this exposure led to subsequent cardiac injury. He was diagnosed with acute carbon monoxide poisoning-induced cardiomyopathy due to an unsafe working environment. According to the results, the risk of exposure to noxious chemicals such as carbon monoxide by workers in the food service industry is potentially high, and workers in this sector should be educated and monitored by the occupational health service to prevent adverse effects.

We report the incidence of ischaemic cardiac toxicity in a contemporary cohort of patients receiving conventional (CFRT) or hypofractionated (HFRT) radiation after surgery for early breast cancer and investigate the interplay of cardiac risk factors and fractionation. Included were patients receiving external beam radiation treatment from 2002 to 2006 at the Christchurch public hospital. Hospital coding databases, oncology databases and medical records were reviewed for baseline characteristics, treatment details and outcomes. The primary outcome was cardiac toxicity (including myocardial infarction, admission for cardiac chest pain, coronary angiogram positivity and ischaemic cardiac death). Kaplan-Meier methods were used to derive ischaemic cardiac event free and overall survival. Predefined univariate and multivariate analysis was performed to investigate interaction with radiation fraction size, cardiac risk factors, age and side of cancer. Standardised mortality ratios were constructed. Five hundred and one patients were identified, 220 treated with CFRT and 281 with HFRT. The median age was 56 and median follow-up 10.33 years. The 10-year breast cancer specific survival was 81.8% (95% CI %.78.1-85.0). The 10-year freedom from cardiac death was 98.6% (95% CI 96.9-99.4). There were 27 post radiation cardiac events including 5 cardiac deaths and 19 cases of acute myocardial infarction. 265 (53%) had at least one cardiac risk factor. Twenty five of the 27 patients with a cardiac event had cardiac risk factors. On univariate and multivariate analysis, fractionation schedule was not significantly associated with a post radiation ischaemic event, however, there was a significant relationship with age and the presence of a cardiac risk factor. The standardised mortality ratio was 0.89 (95% CI: 0-3.13). Our study has shown a low rate of ischaemic cardiac disease for both CFRT and HFRT in women treated for breast cancer with no evidence of an effect with fractionation schedule. Coexisting cardiac risk factors are common in the population. © 2018 The Royal Australian and New Zealand College of Radiologists.

We wanted to determine the accuracy of transthoracic ultrasound in the prediction of chest wall infiltration by lung cancer or lung infiltration by chest wall tumours. Patients having preoperative CT-scan suspect for lung/chest wall infiltration were prospectively enrolled. Inclusion criteria for lung cancer were: obliteration of extrapleural fat, obtuse angle between tumour and chest wall, associated pleural thickening. The criteria for chest wall tumours were: rib destruction and intercostal muscles infiltration with extrapleural fat obliteration and intrathoracic extension. Lung cancer patients with evident chest wall infiltration were excluded. Transthoracic ultrasound was preoperatively performed. Predictions were checked during surgical intervention. Twenty-three patients were preoperatively examined. Sensitivity, specificity, positive and negative predictive values of transthoracic ultrasound were 88.89%, 100%, 100% and 93.3%, respectively. Youden index was used to determine the best cut-off for tumour size in predicting lung/chest wall infiltration: 4.5cm. At univariate logistic regression, tumour size (<4.5 vs ≥ 4.5cm) (p=0.0072) was significantly associated with infiltration. Transthoracic ultrasound is a useful instrument for predicting neoplastic lung or chest wall infiltration in cases of suspect CT-scans and could be used as part of the preoperative workup to assess tumour staging and to plan the best surgical approach.

The purpose of this study was to compare the prevalence and impact of work-related musculoskeletal pain in cardiac sonographers to a large control group of peer employees with similar demographics. Cardiac sonographers are known to have high levels of occupational musculoskeletal pain. Comparative studies with other employees within cardiology/radiology departments have never been performed. An electronic survey was administered to Mayo Clinic employees at six major patient care facilities in four different states. There were 2682 employees within the departments of cardiology and radiology who were contacted, and 1532 (57%) completed the survey. After excluding those who wore protective lead aprons, 517 employees comprised the control group and 66 cardiac sonographers made up the study group. Cardiac sonographers reported work-related musculoskeletal pain more frequently than the control group (88% vs 40%; P<.001). This association persisted after multivariable adjustment for age, sex, body mass index, length of current employment, and history of preexisting musculoskeletal pain (OR 11.6; [95% CI 5.32, 25.5]; P<.001). Cardiac sonographers sought medical care for their work-related pain more often (55% vs 21%; P<.001) and missed more work due to pain (35% vs 12%, P<.001). In a secondary analysis, cardiac sonographers also experienced more work-related musculoskeletal pain than nurses, technicians, and physicians working in the interventional laboratory who regularly wear a protective lead apron (P<.001). In this multisite cross-sectional study, cardiac sonographers experienced significantly more work-related pain and missed more work due to pain than peer employees within cardiology/radiology departments. © 2016, Wiley Periodicals, Inc.

Rib fixation for severe chest deformity due to multiple rib fractures.

2012-01-01

The operative indications for rib fracture repair have been a matter of debate. However, several reports have suggested that flail chest, pain on respiration, and chest deformity/defect are potential conditions for rib fracture repair. We describe our experience of rib fixation in a patient with severe chest deformity due to multiple rib fractures. A 70-year-old woman was admitted with right-sided multiple rib fractures (2nd to 7th) and marked chest wall deformity without flailing caused by an automobile accident. Collapse of the chest wall was observed along the middle anterior axillary line. At 11 days after the injury, surgery was performed to repair the chest deformity, as it was considered to pose a risk of restrictive impairment of pulmonary function or chronic intercostal pain in the future. Operative findings revealed marked displacement of the superior 4 ribs, from the 2nd to the 5th, and collapse of the osseous chest wall towards the thoracic cavity. After exposure of the fracture regions, ribs fixations were performed using rib staplers. The total operation time was 90 minutes, and the collapsed portion of the chest wall along the middle anterior axillary line was reconstructed successfully.

The value of exercise electrocardiogram (ExECG) in symptomatic female patients with low to intermediate risk for significant coronary artery disease (CAD) has been under debate for many years, and nondiagnostic or even erroneous test results are frequently encountered. Cardiac-CT may be more appropriate to exclude CAD in women. This study compares the results of ExECGs with those of cardiac-CTs, performed within a time frame of 1 month in an all-comers female chest pain population. Five hundred fifty-one consecutive female patients from a patient registry were included. ExECGs were negative in 324 (59%), positive in 14 (3%), and nondiagnostic in 213 (39%) patients. CAD was revealed by cardiac-CT in 57% of the women with negative ExECG. No signs of CAD were present on cardiac-CT in 64% of the women with a positive ExECG. Cardiac-CT showed presence of CAD in 268/551 (49%) patients, of whom 56/268 (21%) was diagnosed with ≥50% stenosis. The ExECG of the latter group was negative in 26 (46%), inconclusive in 29 (52%), and positive in 1 (2%). Considering ≥50% stenosis at cardiac-CT as the reference, sensitivity, specificity, PPV, and NPV of ExECG for the present population were 3.7%, 95.7%, 7.1%, and 91.7%, respectively. Similar diagnostic performance was calculated when considering ≥70% stenosis at cardiac-CT as the reference. ExECG failed to detect CAD in more than half of this cohort and in almost half of women with >50% stenosis at cardiac-CT. Importantly, no CAD was detected by cardiac-CT in 64% of women with a positive ExECG. ExECG is therefore questionable as a diagnostic strategy in women with low-to-intermediate risk of CAD, although prospective studies are warranted to determine whether replacing ExECG by cardiac-CT provides better prognoses.

[Chronic chest pain after rib fracture: It can cause a disability?

The rib fractures and instability of the chest wall are the main lesions of closed chest trauma. These lesions can be a source of chronic, often disabling with daily discomfort resulting limitation of some activities. The objective of this study was to assess the prevalence of this phenomenon in order to improve the quality of early care. Through an observational retrospective cohort study on a number of 41 patients supported and monitored for traumatic rib fractures at the Military Hospital of Meknes during the period from October 2010 to March 2016. The circumstances of the accident were dominated by accidents of public roads (86%) and concerned the young adult male. Radiographs have enumerated 165 fracture lines with an average of 4 rib fractures per patient. These were unilateral fractures in 88% of cases, and concerned the means arc in 46% of cases. The rib fracture was undisplaced fracture in 39% of patients, whereas in 2 patients, a flail chest was present. Post-traumatic hemothorax (63% of cases) were the thoracic lesions most commonly associated with rib fractures. The initial management consisted in the use of analgesics systemically in all patients. The retrospective evaluation of pain by the verbal scale was possible in 30 patients. The persistent pain was noted in 60% of cases. This pain was triggered by a simple effort to moderate in 55% of cases, and hard effort in 28% of cases. In 17% of patients, even at rest, the pain occurred intermittently. The impact in terms of disability was mild to moderate in 28% of cases and important in 17%. The neuropathic pain was found in 3 patients. Therapeutically, the first and second levels of analgesics were sufficient to relieve pain. The neuroleptics were required for 2 patients. Our study confirms the persistence of chronic painful, sometimes lasting several years after the initial chest trauma. This pain is responsible of disability triggered most often after exercise.

Excessive radiation exposure remains a concern for patients with symptoms suggesting acute coronary syndrome and pulmonary embolism but must be judged in the perspective of pretest probability and outcomes. We quantify and qualify the pretest probability, outcomes, and radiation exposure of adults with both chest pain and dyspnea. This was a prospective, 4-center, outcomes study. Patients were adults with dyspnea and chest pain, nondiagnostic ECGs, and no obvious diagnosis. Pretest probability for both acute coronary syndrome and pulmonary embolism was assessed with a validated method; ultralow risk was defined as pretest probability less than 2.5% for both acute coronary syndrome and pulmonary embolism. Patients were followed for diagnosis and total medical radiation exposure for 90 days. Eight hundred forty patients had complete data; 23 (3%) had acute coronary syndrome and 15 (2%) had pulmonary embolism. The cohort received an average of 4.9 mSv radiation to the chest, 48% from computed tomography pulmonary angiography. The pretest probability estimates for acute coronary syndrome and pulmonary embolism were less than 2.5% in 227 patients (27%), of whom 0 of 277 (0%; 95% confidence interval 0% to 1.7%) had acute coronary syndrome or pulmonary embolism and 7 of 227 (3%) had any significant cardiopulmonary diagnosis. The estimated chest radiation exposure per patient in this ultralow-risk group was 3.5 mSv, including 26 (3%) with greater than 5 mSv radiation to the chest and no significant cardiopulmonary diagnosis. One quarter of patients with chest pain and dyspnea had ultralow risk and no acute coronary syndrome or pulmonary embolism but were exposed to an average of 3.5 mSv radiation to the chest. These data can be used in a clinical guideline to reduce radiation exposure. Copyright © 2013 American College of Emergency Physicians. Published by Mosby, Inc. All rights reserved.

Chest compressions are a core element of cardio-pulmonary resuscitation. Despite periodic training, real-life chest compressions have been reported to be overly shallow and/or fast, very likely affecting patient outcomes. We investigated the effect of a brief Crew Resource Management (CRM) training program on the correction rate of improperly executed chest compressions in a simulated cardiac arrest scenario. Final-year medical students (n = 57) were randomised to receive a 10-min computer-based CRM or a control training on ethics. Acting as team leaders, subjects performed resuscitation in a simulated cardiac arrest scenario before and after the training. Team members performed standardised overly shallow and fast chest compressions. We analysed how often the team leader recognised and corrected improper chest compressions, as well as communication and resuscitation quality. After the CRM training, team leaders corrected improper chest compressions (35.5%) significantly more often compared with those undergoing control training (7.7%, p = 0.03*). Consequently, four students have to be trained (number needed to treat = 3.6) for one improved chest compression scenario. Communication quality assessed by the Leader Behavior Description Questionnaire significantly increased in the intervention group by a mean of 4.5 compared with 2.0 (p = 0.01*) in the control group. A computer-based, 10-min CRM training improved the recognition of ineffective of chest compressions. Furthermore, communication quality increased. As guideline-adherent chest compressions have been linked to improved patient outcomes, our CRM training might represent a brief and affordable approach to increase chest compression quality and potentially improve patient outcomes.

Fractures of the chest wall include sternum and rib fractures. Traditionally they are managed conservatively due to the anatomy of the rib cage that allows most of them to remain stable and to form a callus that unites the fractured segments. In spite of this management, some patients present with chronic pain or instability of the wall which makes them require some type of fixation. The present article performs a literature review based on 4 cases. The first case was a 61 year-old man with blunt chest trauma, with a great deformity of the chest wall associated with subcutaneous emphysema, and pneumothorax. The second case was a 51 year-old man with blunt chest trauma, initially managed at another institution, who despite treatment, had persistent pain and dyspnoea. The third case was a 30 year-old man that suffered a motor vehicle accident, with resulting pain and crepitation of the rib cage and with diagnostic images showing multiple rib fractures. The last case is a 62 year-old man that fell down the stairs, with blunt chest trauma with high intensity pain, dyspnoea and basal ipsilateral hypoventilation. Rib fracture fixation offers a good alternative in selected patients to decrease associated morbidity, leading to a patient's fast return to his or her working life.

Methods related to experimental human pain research aim at activating different nociceptors, evoke pain from different organs and activate specific pathways and mechanisms. The different possibilities for using mechanical, electrical, thermal and chemical methods in visceral pain research are discussed with emphasis of combinations (e.g., the multimodal approach). The methods have been used widely in assessment of pain mechanisms in the esophagus and have contributed to our understanding of the symptoms reported in these patients. Hence abnormal activation and plastic changes of central pain pathways seem to play a major role in the symptoms in some patients with gastro-esophageal reflux disease and in patients with functional chest pain of esophageal origin. These findings may lead to an alternative approach for treatment in patients that does not respond to conventional medical or surgical therapy. PMID:16718803

Background Variability in patients' postoperative pain experience and response to treatment challenges effective pain management. Variability in pain reflects individual differences in inhibitory pain modulation and psychological sensitivity, which in turn may be clinically relevant for the disposition to acquire pain. The aim of this study was to investigate the effects of conditioned pain modulation and situational pain catastrophizing on postoperative pain and pain persistency. Methods Preoperatively, 42 healthy males undergoing funnel chest surgery completed the Spielberger's State-Trait Anxiety Inventory and Beck's Depression Inventory before undergoing a sequential conditioned pain modulation paradigm. Subsequently, the Pain Catastrophizing Scale was introduced and patients were instructed to reference the conditioning pain while answering. Ratings of movement-evoked pain and consumption of morphine equivalents were obtained during postoperative days 2–5. Pain was reevaluated at six months postoperatively. Results Patients reporting persistent pain at six months follow-up (n = 15) were not significantly different from pain-free patients (n = 16) concerning preoperative conditioned pain modulation response (Z = 1.0, P = 0.3) or level of catastrophizing (Z = 0.4, P = 1.0). In the acute postoperative phase, situational pain catastrophizing predicted movement-evoked pain, independently of anxiety and depression (β = 1.0, P = 0.007) whereas conditioned pain modulation predicted morphine consumption (β = −0.005, P = 0.001). Conclusions Preoperative conditioned pain modulation and situational pain catastrophizing were not associated with the development of persistent postoperative pain following funnel chest repair. Secondary outcome analyses indicated that conditioned pain modulation predicted morphine consumption and situational pain catastrophizing predicted movement-evoked pain intensity in the acute postoperative phase. These findings may have important implications for developing strategies to treat or prevent acute postoperative pain in selected patients. Pain may be predicted and the malfunctioning pain inhibition mechanism as tested with CPM may be treated with suitable drugs augmenting descending inhibition. PMID:24587268

Introduction Our goal was to reduce ordering of coagulation studies in the emergency department (ED) that have no added value for patients presenting with chest pain. We hypothesized this could be achieved via implementation of a stopgap measure in the electronic medical record (EMR). Methods We used a pre and post quasi-experimental study design to evaluate the impact of an EMR-based intervention on coagulation study ordering for patients with chest pain. A simple interactive prompt was incorporated into the EMR of our ED that required clinicians to indicate whether patients were on anticoagulation therapy prior to completion of orders for coagulation studies. Coagulation order frequency was measured via detailed review of randomly sampled encounters during two-month periods before and after intervention. We classified existing orders as clinically indicated or non-value added. Order frequencies were calculated as percentages, and we assessed differences between groups by chi-square analysis. Results Pre-intervention, 73.8% (76/103) of patients with chest pain had coagulation studies ordered, of which 67.1% (51/76) were non-value added. Post-intervention, 38.5% (40/104) of patients with chest pain had coagulation studies ordered, of which 60% (24/40) were non-value added. There was an absolute reduction of 35.3% (95% confidence interval [CI]: 22.7%, 48.0%) in the total ordering of coagulation studies and 26.4% (95% CI: 13.8%, 39.0%) in non-value added order placement. Conclusion Simple EMR-based interactive prompts can serve as effective deterrents to indiscriminate ordering of diagnostic studies. PMID:28210363

Telemetric cardiac monitoring was invented in 1949 by Norman J Holter. Its clinical use started in the early 1960s. In the hospital, biotelemetry allows early mobilization of patients with cardiovascular risk and addresses the need for arrhythmia or oxygen saturation monitoring. Nowadays telemetry either uses vendor-specific UHF band broadcasting or the digital ISM band (Industrial, Scientific, and Medical Band) standardized Wi-Fi network technology. Modern telemetry radio transmitters can measure and send multiple physiological parameters like multi-channel ECG, NIPB and oxygen saturation. The continuous measurement of oxygen saturation is mandatory for the remote monitoring of patients with cardiac pacemakers. Real 12-lead ECG systems with diagnostic quality are an advantage for monitoring patients with chest pain syndromes or in drug testing wards. Modern systems are light-weight and deliver a maximum of carrying comfort due to optimized cable design. Important for the system selection is a sophisticated detection algorithm with a maximum reduction of artifacts. Home-monitoring of implantable cardiac devices with telemetric functionalities are becoming popular because it allows remote diagnosis of proper device functionality and also optimization of the device settings. Continuous real-time monitoring at home for patients with chronic disease may be possible in the future using Digital Video Broadcasting Terrestrial (DVB-T) technology in Europe, but is currently not yet available.

An ideal organ-specific insert phantom should be able to simulate the anatomical features with appropriate appearances in the resultant computed tomography (CT) images. This study investigated a 3D printing technology to develop a novel and cost-effective cardiac insert phantom derived from volumetric CT image datasets of anthropomorphic chest phantom. Cardiac insert volumes were segmented from CT image datasets, derived from an anthropomorphic chest phantom of Lungman N-01 (Kyoto Kagaku, Japan). These segmented datasets were converted to a virtual 3D-isosurface of heart-shaped shell, while two other removable inserts were included using computer-aided design (CAD) software program. This newly designed cardiac insert phantom was later printed by using a fused deposition modelling (FDM) process via a Creatbot DM Plus 3D printer. Then, several selected filling materials, such as contrast media, oil, water and jelly, were loaded into designated spaces in the 3D-printed phantom. The 3D-printed cardiac insert phantom was positioned within the anthropomorphic chest phantom and 30 repeated CT acquisitions performed using a multi-detector scanner at 120-kVp tube potential. Attenuation (Hounsfield Unit, HU) values were measured and compared to the image datasets of real-patient and Catphan ® 500 phantom. The output of the 3D-printed cardiac insert phantom was a solid acrylic plastic material, which was strong, light in weight and cost-effective. HU values of the filling materials were comparable to the image datasets of real-patient and Catphan ® 500 phantom. A novel and cost-effective cardiac insert phantom for anthropomorphic chest phantom was developed using volumetric CT image datasets with a 3D printer. Hence, this suggested the printing methodology could be applied to generate other phantoms for CT imaging studies. © 2018 The Authors.

Systemic autoimmune diseases are themselves a relevant and independent risk factor for atherosclerosis and coronary ectasia. We describe a case of a 58-year-old Caucasian man who was admitted to our department for unstable angina. History of asthma, paranasal sinus abnormality, and peripheral eosinophilia given a high suspicion of Churg-Strauss syndrome (CSS). Diagnosis was performed with 5 of the 6 American College of Rheumatology criteria. The knowledge that CSS is often associated with significant coronary artery involvement and the persistence of chest pain led us to performing immediately a coronary angiography. Coronary angiography showed diffuse ectasic lesions, chronic occlusion of left anterior descending artery with homocoronary collateral circulation from left circumflex artery and subocclusive stenosis in the proximal tract of posterior descending artery. The early recognition of CSS, an aggressive invasive diagnostic approach, and an early appropriate therapy are important to prevent the progressive and permanent cardiac damage in these patients. In the setting of a multidisciplinary approach, careful cardiac assessment is an essential step in CSS, even in mildly symptomatic patients. Copyright © 2015 Cardiological Society of India.

A 29-year-old man was admitted with fevers, cough, left-sided chest pain and lethargy for 1 week. He had a cardiac transplant 10 years prior and was on immunosuppressive drugs. He was found to have a pulmonary lesion and went on to develop a lung abscess. Propionibacterium acnes was identified on matrix-assisted laser desorption ionisation mass spectrometry-time of flight and 16s rRNA gene sequencing after drainage. He was curatively treated with co-trimoxazole and co-amoxiclav. He divulged a longstanding history of seborrhoeic dermatitis with frequent flares leading to large volumes of squames collecting on his bed sheets. We hypothesise this was a possible route of entry: inhalation of the Propionibacterium. This case highlights how a common commensal bacterium, P. acnes, was able to cause pathology in an immunosuppressed patient. This is the only case of a patient with transplantation developing a P. acnes pulmonary infection and the only case of P. acnes causing these clinical features to be reported in the literature. 2015 BMJ Publishing Group Ltd.

To investigate (1) cardiopulmonary resuscitation (CPR) adequacy during simulated cardiac arrest of equipped football players and (2) whether protective football equipment impedes CPR performance measures. Exploratory crossover study performed on Laerdal SimMan 3 G interactive manikin simulator. Temple University/St Luke's University Health Network Regional Medical School Simulation Laboratory. Thirty BCLS-certified ATCs and 6 ACLS-certified emergency department technicians. Subjects were given standardized rescuer scenarios to perform three 2-minute sequences of compression-only CPR. Baseline CPR sequences were captured on each subject. Experimental conditions included 2-minute sequences of CPR either over protective football shoulder pads or under unlaced pads. Subjects were instructed to adhere to 2010 American Heart Association guidelines (initiation of compressions alone at 100/min to 51 mm). Dependent variables included average compression depth, average compression rate, percentage of time chest wall recoiled, and percentage of hands-on contact during compressions. Differences between subject groups were not found to be statistically significant, so groups were combined (n = 36) for analysis of CPR compression adequacy. Compression depth was deeper under shoulder pads than over (P = 0.02), with mean depths of 36.50 and 31.50 mm, respectively. No significant difference was found with compression rate or chest wall recoil. Chest compression depth is significantly decreased when performed over shoulder pads, while there is no apparent effect on rate or chest wall recoil. Although the clinical outcomes from our observed 15% difference in compression depth are uncertain, chest compression under the pads significantly increases the depth of compressions and more closely approaches American Heart Association guidelines for chest compression depth in cardiac arrest.

Coordination of the tasks of performing chest compressions and defibrillation can lead to communication challenges that may prolong time spent off the chest. The purpose of this study was to determine whether defibrillation provided by the provider performing chest compressions led to a decrease in peri-shock pauses as compared to defibrillation administered by a second provider, in a simulated cardiac arrest scenario. This was a randomized, controlled study measuring pauses in chest compressions for defibrillation in a simulated cardiac arrest model. We approached hospital providers with current CPR certification for participation between July, 2011 and October, 2011. Volunteers were randomized to control (facilitator-administered defibrillation) or experimental (compressor-administered defibrillation) groups. All participants completed one minute of chest compressions on a mannequin in a shockable rhythm prior to administration of defibrillation. We measured and compared pauses for defibrillation in both groups. Out of 200 total participants, we analyzed data from 197 defibrillations. Compressor-initiated defibrillation resulted in a significantly lower pre-shock hands-off time (0.57 s; 95% CI: 0.47-0.67) compared to facilitator-initiated defibrillation (1.49 s; 95% CI: 1.35-1.64). Furthermore, compressor-initiated defibrillation resulted in a significantly lower peri-shock hands-off time (2.77 s; 95% CI: 2.58-2.95) compared to facilitator-initiated defibrillation (4.25 s; 95% CI: 4.08-4.43). Assigning the responsibility for shock delivery to the provider performing compressions encourages continuous compressions throughout the charging period and decreases total time spent off the chest. However, as this was a simulation-based study, clinical implementation is necessary to further evaluate these potential benefits.

Blood pro-B-type natriuretic peptide (pro-BNP) level increases in case of myocardial ischemia and myocardial volume or pressure overload. The aim of this study is to measure changes in blood pro-BNP level during the course of panic attack with symptoms of chest pain and/or dyspnea. Patients who were admitted to the emergency room with panic attack have been regarded as the study group. Blood pro-BNP level has been measured during follow-up of the patients upon admission and 2h later. Systolic and diastolic blood pressure and pulse rate were significantly decreased (p<0.0001) during follow-up of the patients (ages between 18 and 43 years; mean 26+/-6.13 years). Paradoxically, blood pro-BNP level of patients was significantly increased during the same period (52.86+/-59.73 versus 50.97+/-57.42 U/L; p<0.0001). Blood pro-BNP level has increased among patients who have complained chest pain and/or dyspnea as symptoms of panic attack. It is thought that chest pain and dyspnea in the course of panic attack may not be purely psychological.

The availability of two-dimensional echocardiography as a clinical tool has led to an interest in its applicability, usefulness, and reliability in the evaluation of blunt cardiac trauma. Forty patients who sustained objective evidence of blunt chest trauma were evaluated at our institution using serial ECGs, creatine phosphokinase (CPK) isoenzyme determinations, and two-dimensional echocardiography. Twenty patients (50%) manifested evidence of cardiac injury as demonstrated by abnormal ECGs, elevated CPK isoenzymes, or abnormal echocardiograms. Nine (23%) patients had abnormal echocardiograms with findings of pericardial effusions in four, chamber enlargement in three, and echodense areas of the right ventricle in two. There was no correlation with ECG changes or the presence of CPK isoenzymes. Based on these observations we believe echocardiography can be used as a noninvasive modality to complement other clinical tools in the detection of blunt cardiac injury.

Varicella zoster virus (VZV) infection can cause temporary acquired protein S or C deficiency via cross reacting antibodies and consequently inducing a hypercoagulable state. A 6-year-old girl with a history of congenital cardiac disease was seen at an Emergency Department with acute chest pain, dyspnoea and fever, seven days after developing chicken pox. Diagnostic tests revealed massive infarction of the spleen, and a protein S and C deficiency. In addition, blood cultures revealed a Lancefield group A β-haemolytic streptococcus (GABHS). The patient recovered fully after treatment with low molecular weight heparin and antibiotics. In this patient, septic emboli caused splenic infarction. Thromboembolic complications should be suspected in children with VZV who present with acute symptoms, in particular if bacterial superinfection is found.

Pseudoephedrine, a common ingredient in cold relief drugs, dietary supplements and Chinese herbal tea, has potent sympathomimetic effects, impacting the cardiovascular system. The chemical properties and clinical effects of pseudoephedrine are similar to those of ephedrine, and its main effect is caused by the release of endogenous norepinephrine. A 45-year-old man who presented with chest pain following ingestion of pseudoephedrine-containing prescription medication is described. The patient was initially diagnosed with inferior myocardial infarction based on an electrocardiogram, and intravenous metoprolol was started pending coronary artery angiography. Metoprolol reversed the ST segment elevation and relieved the symptoms, and coronary angiography showed normal coronary arteries. The present case highlights beta-blocker therapy as part of an initial intervention of pseudoephedrine-related cardiac symptoms. PMID:18987767

Hypertrophic cardiomyopathy is the most common inherited cardiovascular disease. It is characterized by increased ventricular wall thickness and is highly complex due to its heterogeneous clinical presentation, several phenotypes, large number of associated causal mutations and broad spectrum of complications. It is caused by mutations in sarcomeric proteins, which are identified in up to 60% of cases of the disease. Clinical manifestations of Hypertrophic Cardiomyopathy include shortness of breath, chest pain, palpitations and syncope, which are related to the onset of diastolic dysfunction, left ventricular outflow tract obstruction, ischemia, atrial fibrillation and abnormal vascular responses. It is associated with an increased risk of sudden cardiac death, heart failure and thromboembolic events. In this article, we discuss the diagnostic and therapeutic aspects of this disease.

We reported a case of patent ductus arteriosus (PDA) with congenital anomaly of coronary arteries as abnormal origin of right coronary artery (RCA) and left coronary artery (LCA) from a single ostium of the right coronary sinus. A 21-year-old man referred to our institution for evaluation of cardiac murmur. He has suffered from palpitation and atypical chest pain for three months. On physical examination, a continuous murmur was heard in the second left parasternal space. Transthoracic echocardiography showed normal left and right ventricular size and systolic function (LVEF = 55%). Main pulmonary artery (PA) and left pulmonary artery (LPA) branch were considerably dilated. Considering normal coronary flow, lack of clinical evidence of myocardial ischemia and echocardiography findings, patient underwent surgical closure of PDA via left thoracotomy and after five days discharged uneventfully.

Hemodialysis is the first extrarenal treatment method that allowed supporting patients in terminal chronic failure in Senegal since 1997. 25 years later, we conducted this study to determine the type and the prevalence of different cardiovascular complications and identify the main cardiovascular risk factors. It is a retrospective study of 4 years. 38 patients treated at least 6 months in hemodialysis and cardiovascular explorations with a front chest x-ray, electrocardiogram and cardiac ultrasound. All patients who have not started hemodialysis, treated less than 6 months in hemodialysis, treaties in peritoneal dialysis or having raised cardiovascular explorations were excluded. For each selected patient, we collected data epidemiological, clinical, paraclinical and evolutionary aspects of cardiovascular complications. 38 patients were included in this study. The average age was 52 years ± 12.85 and the sex ratio H/F of 1.53. Initial nephropathy was dominated by the néphroangiosclérose followed by diabetic nephropathy. Clinically the signs of appeal are marked by the effort dyspnea palpitations, chest pain and physically by the HTA, anemia. Cardiovascular complications were dominated by hypertrophy (LVH) left ventricular, rhythm type of arrhythmia disorders valvular leakage (mitral and tricuspid) and cerebral vascular accident (stroke). The average impact of LVH according the HTA is 81%, by sex of 78.26% for men and 60% for women. At the end of the study, 27 patients were pursuing hemodialysis and 11 had died 6 (54%) of cardiovascular cause. Hemodialysis is a common purification technique in Senegal and its complications remain especially dominated by abuses cardiovascular.

Acute chest pain after bench press exercise in a healthy young adult.

Bench press exercise, which involves repetitive lifting of weights to full arm extension while lying supine on a narrow bench, has been associated with complications ranging in acuity from simple pectoral muscle strain, to aortic and coronary artery dissection. A 39-year-old man, physically fit and previously asymptomatic, presented with acute chest pain following bench press exercise. Diagnostic evaluation led to the discovery of critical multivessel coronary occlusive disease, and subsequently, highly elevated levels of lipoprotein (a). Judicious use of ancillary testing may identify the presence of "high-risk" conditions in a seemingly "low-risk" patient. Emergency department evaluation of the young adult with acute chest pain must take into consideration an extended spectrum of potential etiologies, so as to best guide appropriate management.

A prospective evaluation of 68 patients suffering blunt chest trauma for evidence of cardiac injury.

The prevalence and significance of cardiac injury following blunt chest trauma is largely unknown. Although electrocardiography (ECG) and creatinine phosphokinase isoenzyme (CPK-MB) determination have traditionally been used in determining cardiac injury, recent developments in two-dimensional echocardiography (ECHO) as a noninvasive diagnostic tool have led to its use in detecting structural cardiac damage following trauma. In an attempt to determine the occurrence and consequences of cardiac injury we prospectively evaluated 68 patients at one institution using ECHO, serial ECG, and serial CPK-MB determinations in the first 3 days following hospital admission. Patients were selected who had evidence of blunt chest injury on examination or by mechanism of injury. The mean age of the 68 patients was 36.3 +/- 19.6 years and the mean Injury Severity Score, 21.5 +/- 11.6. Forty-nine patients (72%) were found to have an abnormal ECHO, ECG, or CPK-MB (greater than 3%). Eighteen patients (26%) had abnormal ECHOs consisting of seven right ventricular contusions, three left ventricular contusions, three contusions of both chambers, four pericardial effusions, and one small ventricular septal defect. Only three contusions were associated with elevated CPK-MB and seven with abnormal ECGs. Abnormalities of ECG included 18 patients with S-T, T wave changes, axis shifts (11 patients), and bundle branch or hemiblocks (10 patients). No patient died or experienced serious morbidity as a result of their cardiac injury, including 12 patients who underwent surgical procedures with general anesthesia within 30 days of admission.(ABSTRACT TRUNCATED AT 250 WORDS)

Coronary artery calcification (CAC) is a strong and independent predictor of cardiovascular events (CVEs). CAC can be quantified in chest CT scans acquired in lung screening. However, in these images the reproducibility of CAC quantification is compromised by cardiac motion that occurs during scanning, thereby limiting the reproducibility of CVE risk assessment. We present a system for the identification of CACs strongly affected by cardiac motion artifacts by using a convolutional neural network (CNN). This study included 125 chest CT scans from the National Lung Screening Trial (NLST). Images were acquired with CT scanners from four different vendors (GE, Siemens, Philips, Toshiba) with varying tube voltage, image resolution settings, and without ECG synchronization. To define the reference standard, an observer manually identified CAC lesions and labeled each according to the presence of cardiac motion: strongly affected (positive), mildly affected/not affected (negative). A CNN was designed to automatically label the identified CAC lesions according to the presence of cardiac motion by analyzing a patch from the axial CT slice around each lesion. From 125 CT scans, 9201 CAC lesions were analyzed. 8001 lesions were used for training (19% positive) and the remaining 1200 (50% positive) were used for testing. The proposed CNN achieved a classification accuracy of 85% (86% sensitivity, 84% specificity). The obtained results demonstrate that the proposed algorithm can identify CAC lesions that are strongly affected by cardiac motion. This could facilitate further investigation into the relation of CAC scoring reproducibility and the presence of cardiac motion artifacts.

Nearly half of Operation Enduring Freedom/Operation Iraqi Freedom veterans experience continued pain post-deployment. Several investigations report analgesic effects of allopregnanolone and other neurosteroids in animal models, but few data are currently available focusing on neurosteroids in clinical populations. Allopregnanolone positively modulates GABA(A) receptors and demonstrates pronounced analgesic and anxiolytic effects in rodents, yet studies examining the relationship between pain and allopregnanolone in humans are limited. We thus hypothesized that endogenous allopregnanolone and other neurosteroid levels may be negatively correlated with self-reported pain symptoms in humans. We determined serum neurosteroid levels by gas chromatography/mass spectrometry (allopregnanolone, pregnenolone) or radioimmunoassay (dehydroepiandrosterone [DHEA], progesterone, DHEA sulfate [DHEAS]) in 90 male veterans who served in the U.S. military after September 11, 2001. Self-reported pain symptoms were assessed in four areas (low back pain, chest pain, muscle soreness, headache). Stepwise linear regression analyses were conducted to investigate the relationship between pain assessments and neurosteroids, with the inclusion of smoking, alcohol use, age, and history of traumatic brain injury as covariates. Durham VA Medical Center. Allopregnanolone levels were inversely associated with low back pain (P=0.044) and chest pain (P=0.013), and DHEA levels were inversely associated with muscle soreness (P=0.024). DHEAS levels were positively associated with chest pain (P=0.001). Additionally, there was a positive association between traumatic brain injury and muscle soreness (P=0.002). Neurosteroids may be relevant to the pathophysiology of self-reported pain symptoms in this veteran cohort, and could represent future pharmacological targets for pain disorders.

This diagnostic accuracy study describes the performance of 5 accelerated chest pain pathways, calculated with the new Beckman's Access high-sensitivity troponin I assay. High-sensitivity troponin I was measured with presentation and 2-hour blood samples in 1,811 patients who presented to an emergency department (ED) in Australia. Patients were classified as being at low risk according to 5 rules: modified accelerated diagnostic protocol to assess patients with chest pain symptoms using troponin as the only biomarker (m-ADAPT), the Emergency Department Assessment of Chest Pain Score (EDACS) pathway, the History, ECG, Age, Risk Factors, and Troponin (HEART) pathway, the No Objective Testing Rule, and the new Vancouver Chest Pain Rule. Endpoints were 30-day acute myocardial infarction and acute coronary syndrome. Measures of diagnostic accuracy for each rule were calculated. Data included 96 patients (5.3%) with acute myocardial infarction and 139 (7.7%) with acute coronary syndrome. The new Vancouver Chest Pain Rule and No Objective Testing Rule had high sensitivity for acute myocardial infarction (100%; 95% confidence interval [CI] 96.2% to 100% for both) and acute coronary syndrome (98.6% [95% CI 94.9% to 99.8%] and 99.3% [95% CI 96.1% to 100%]). The m-ADAPT, EDACS, and HEART pathways also yielded high sensitivity for acute myocardial infarction (96.9% [95% CI 91.1% to 99.4%] for m-ADAPT and 97.9% [95% CI 92.7% to 99.7%] for EDACS and HEART), but lower sensitivity for acute coronary syndrome (≤95.0% for all). The m-ADAPT, EDACS, and HEART rules classified more patients as being at low risk (64.3%, 62.5%, and 49.8%, respectively) than the new Vancouver Chest Pain Rule and No Objective Testing Rule (28.2% and 34.5%, respectively). In this cohort with a low prevalence of acute myocardial infarction and acute coronary syndrome, using the Beckman's Access high-sensitivity troponin I assay with the new Vancouver Chest Pain Rule or No Objective Testing Rule enabled approximately one third of patients to be safely discharged after 2-hour risk stratification with no further testing. The EDACS, m-ADAPT, or HEART pathway enabled half of ED patients to be rapidly referred for objective testing. Copyright © 2017 American College of Emergency Physicians. Published by Elsevier Inc.

Patients in cardiac rehabilitation are typically advised to complete a period of supervised endurance training before beginning resistance training. In this study, however, we compared the peak rate-pressure product (RPP, a calculated indicator of myocardial work) of patients during two types of exercise—treadmill walking and chest press—from workout session 1 through completion of cardiac rehabilitation. Twenty-one patients (4 women and 17 men, aged 35 to 70 years) were enrolled in the study; they were referred for cardiac rehabilitation after myocardial infarction, percutaneous coronary intervention, or both. The participants did treadmill walking and chest press exercises during each workout session. Peak values for heart rate (HR) and systolic blood pressure (SBP) were recorded, and the peak RPP was calculated (peak HR ⊠ peak SBP). Paired t tests were used to compare the data collected during the two types of exercise across 19 workout sessions. The mean peak values for HR, SBP, and RPP were lower during resistance training than during endurance training; the differences were statistically significant (P < 0.05), with only one exception (the SBP for session 1). Across all 19 workout sessions, the participants performed more myocardial work, as indicated by the peak RPP, during treadmill walking than during the chest press. PMID:20396420

The use of intracardiac assist devices is expanding, and correct position of these devices is required for optimal functioning. The aortic valve is an important landmark for positioning of those devices. It would be of great value if the device position could be easily monitored on plain supine chest radiograph in the ICU. We introduce a ratio-based tool for determination of the aortic valve location on plain supine chest radiograph images, which can be used to evaluate intracardiac device position. Retrospective observational study. Large academic medical center. Patients admitted to the ICU and supported by an intracardiac assist device. We developed a ratio to determine the aortic valve location on supine chest radiograph images. This ratio is used to assess the position of a cardiac assist device and is compared with echocardiographic findings. Supine anterior-posterior chest radiographs of patients with an aortic valve prosthesis (n = 473) were analyzed to determine the location of the aortic valve. We calculated several ratios with the potential to determine the position of the aortic valve. The aortic valve location ratio, defined as the distance between the carina and the aortic valve, divided by the thoracic width, was found to be the best performing ratio. The aortic valve location ratio determines the location of the aortic valve caudal to the carina, at a distance of 0.25 ± 0.05 times the thoracic width for male patients and 0.28 ± 0.05 times the thoracic width for female patients. The aortic valve location ratio was validated using CT images of patients with angina pectoris without known valvular disease (n = 95). There was a good correlation between cardiac device position (Impella) assessed with the aortic valve location ratio and with echocardiography (n = 53). The aortic valve location ratio enables accurate and reproducible localization of the aortic valve on supine chest radiograph. This tool is easily applicable and can be used for assessment of cardiac device position in patients on the ICU.

Prejudice by medical providers has been found to contribute to differential cardiac risk estimates. As such, empirical examinations of psychological factors associated with such biases are warranted. Considerable psychological research implicates concerns with personal mortality in motivating prejudicial biases. The authors sought to examine whether provoking thoughts of mortality among medical students would engender more cautious cardiac risk assessments for a hypothetical Christian than for a Muslim patient. During the spring of 2007, university medical students (N=47) were randomly assigned to conditions in a 2 (mortality salience) x 2 (patient religion) full factorial experimental design. In an online survey, participants answered questions about their mortality or about future uncertainty, inspected emergency room admittance forms for a Muslim or Christian patient complaining of chest pain, and subsequently estimated risk for coronary artery disease, myocardial infarction, and the combined risk of either of the two. A composite risk index was formed based on the responses (on a scale of 0-100) to each of the 3 cardiac risk questions. Reminders of mortality interacted with patient religion to influence risk assessments, F(1,41)=11.57, P=0.002, eta2 =.22. After being reminded of mortality, participants rendered more serious cardiac risk estimates for a Christian patient (F1,41 =8:66, P=0:01) and less serious estimates for a Muslim patient (F(1,41)=4.08, P=0.05). Reminders of personal mortality can lead to biased patient risk assessment as medical providers use their cultural identification to psychologically manage their awareness of death.

Women report more postoperative pain and problems performing domestic activities than men in the first month of recovery after cardiac surgery. The purpose of this article is to describe how women rate and describe pain interference with daily life after early discharge from cardiac surgery. A qualitative study was conducted in 2004-2005 with ten women recruited from a large Norwegian university hospital before discharge from their first elective cardiac surgery. Various aspects of the women's postoperative experiences were collected with qualitative interviews in the women's homes 8-14 days after discharge: a self-developed pain diary measuring pain intensity, types and amount of pain medication taken every day after returning home from hospital; and the Brief Pain Inventory-Short Form immediately before the interview. Qualitative content analysis was used to identify recurring themes from the interviews. Data from the questionnaires provided more nuances to the experiences of pain, pain management, and interference of postoperative pain. Postoperative pain interfered most with sleep, general activity, and the ability to perform housework during the first 2 weeks after discharge. Despite being advised at the hospital to take pain medication regularly, few women consumed the maximum amount of analgesics. Early hospital discharge after open cardiac surgery implies increased patient participation in pain management. Women undergoing this surgery need more information in hospital on why postoperative pain management beyond simple pain relief is important. (c) 2010 American Society for Pain Management Nursing.

A major hurdle limiting the ability to improve the quality of resuscitation has been the lack of a noninvasive real-time detection system capable of monitoring the quality of cerebral and other organ perfusion, as well as oxygen delivery during cardiopulmonary resuscitation. Here, we report on a novel system of cerebral perfusion targeted resuscitation. An observational study evaluating the role of cerebral oximetry (Equanox; Nonin, Plymouth, MI, and Invos; Covidien, Mansfield, MA) as a real-time marker of cerebral perfusion and oxygen delivery together with the impact of an automated mechanical chest compression system (Life Stat; Michigan Instruments, Grand Rapids, MI) on oxygen delivery and return of spontaneous circulation following in-hospital cardiac arrest. Tertiary medical center. In-hospital cardiac arrest patients (n = 34). Cerebral oximetry provided real-time information regarding the quality of perfusion and oxygen delivery. The use of automated mechanical chest compression device (n = 12) was associated with higher regional cerebral oxygen saturation compared with manual chest compression device (n = 22) (53.1% ± 23.4% vs 24% ± 25%, p = 0.002). There was a significant difference in mean regional cerebral oxygen saturation (median % ± interquartile range) in patients who achieved return of spontaneous circulation (n = 15) compared with those without return of spontaneous circulation (n = 19) (47.4% ± 21.4% vs 23% ± 18.42%, p < 0.001). After controlling for patients achieving return of spontaneous circulation or not, significantly higher mean regional cerebral oxygen saturation levels during cardiopulmonary resuscitation were observed in patients who were resuscitated using automated mechanical chest compression device (p < 0.001). The integration of cerebral oximetry into cardiac arrest resuscitation provides a novel noninvasive method to determine the quality of cerebral perfusion and oxygen delivery to the brain. The use of automated mechanical chest compression device during in-hospital cardiac arrest may lead to improved oxygen delivery and organ perfusion.

To determine how often unnecessary resting echocardiograms that are "not recommended" by clinical practice guidelines are performed in patients with stable chest pain and normal resting electrocardiograms (ECGs). We performed a retrospective search of electronic medical records of all outpatients seen at Mayo Clinic Rochester from January 1, 2010, through December 31, 2013, to identify residents of Olmsted County, Minnesota, with stable chest pain and known or suspected coronary artery disease who underwent resting echocardiography and had normal resting ECGs and no other indication for echocardiography. Of the 8280 outpatients from Olmsted County who were evaluated at Mayo Clinic Rochester with chest pain, 590 (7.1%) had resting echocardiograms. Ninety-two of these 590 patients (15.6%) had normal resting ECGs. Thirty-three of these 92 patients (35.9%) had other indications for echocardiography. The remaining 59 patients (10.0% of all echocardiograms and 0.7% of all patients) had normal resting ECGs and no other indication for echocardiography. Fifty-seven of these 59 patients (96.6%) had normal echocardiograms. Thirteen of these 59 echocardiograms (22.0%) were "preordered" before the provider (physicians, nurses, physician assistants) visit. The overall rate of echocardiography in Olmsted County outpatients with chest pain seen at Mayo Clinic Rochester is low. Only 1 in 10 of these echocardiograms was performed in violation of the class III recommendation in the American College of Cardiology Foundation/American Heart Association guidelines for the management of stable angina. These unnecessary echocardiograms were almost always normal. The rate of unnecessary echocardiograms could be decreased by eliminating preordering.

An accelerated diagnostic protocol for evaluating low-risk patients with acute chest pain in a cardiologist-based chest pain unit (CPU) is widely employed today. However, limited data exist regarding the feasibility of such an algorithm for patients with a history of prior coronary artery disease (CAD). The aim of the current study was to assess the feasibility and safety of evaluating patients with a history of prior CAD using an accelerated diagnostic protocol. We evaluated 1,220 consecutive patients presenting with acute chest pain and hospitalized in our CPU. Patients were stratified according to whether they had a history of prior CAD or not. The primary composite outcome was defined as a composite of readmission due to chest pain, acute coronary syndrome, coronary revascularization, or death during a 60-day follow-up period. Overall, 268 (22%) patients had a history of prior CAD. Non-invasive evaluation was performed in 1,112 (91%) patients. While patients with a history of prior CAD had more comorbidities, the two study groups were similar regarding hospitalization rates (9% vs. 13%, p = 0.08), coronary angiography (13% vs. 11%, p = 0.41), and revascularization (6.5% vs. 5.7%, p = 0.8) performed during CPU evaluation. At 60-days the primary endpoint was observed in 12 (1.6%) and 6 (3.2%) patients without and with a history of prior CAD, respectively (p = 0.836). No mortalities were recorded. To conclude, Patients with a history of prior CAD can be expeditiously and safely evaluated using an accelerated diagnostic protocol in a CPU with outcomes not differing from patients without such a history.

Most patients with acute myocardial infarction (AMI) experience more than one symptom at onset. Although symptoms are an important early indicator, patients and physicians may have difficulty interpreting symptoms and detecting AMI at an early stage. This study aimed to identify symptom clusters among Korean patients with ST-elevation myocardial infarction (STEMI), to examine the relationship between symptom clusters and patient-related variables, and to investigate the influence of symptom clusters on treatment time delay (decision time [DT], onset-to-balloon time [OTB]). This was a prospective multicenter study with a descriptive design that used face-to-face interviews. A total of 342 patients with STEMI were included in this study. To identify symptom clusters, two-step cluster analysis was performed using SPSS software. Multinomial logistic regression to explore factors related to each cluster and multiple logistic regression to determine the effect of symptom clusters on treatment time delay were conducted. Three symptom clusters were identified: cluster 1 (classic MI; characterized by chest pain); cluster 2 (stress symptoms; sweating and chest pain); and cluster 3 (multiple symptoms; dizziness, sweating, chest pain, weakness, and dyspnea). Compared with patients in clusters 2 and 3, those in cluster 1 were more likely to have diabetes or prior MI. Patients in clusters 2 and 3, who predominantly showed other symptoms in addition to chest pain, had a significantly shorter DT and OTB than those in cluster 1. In conclusion, to decrease treatment time delay, it seems important that patients and clinicians recognize symptom clusters, rather than relying on chest pain alone. Further research is necessary to translate our findings into clinical practice and to improve patient education and public education campaigns.

There is no clear data about the optimum time for chest tube removal after coronary artery bypass surgery. The aim of this study was to assess the impact of the chest tube removal time following coronary artery bypass grafting surgery on the clinical outcome of the patients. An analysis of data from 307 patients was performed. The patients were randomized into two groups: in group 1 (N=107) chest tubes were removed within the first 24 hours after surgery, whereas in group 2 (N=200), chest tubes were removed in the second 24 hours after surgery. Demographics, lactate and pH at the beginning, during and after the operation, creatinine, left ventricular ejection fraction, inotropic drugs administration, length of ICU stay, and mortality data were collected. Respiratory rate and pain level was assessed. In these surgeries, the mean± standard deviation for the aortic clamping time was 49.18±17.59 minutes and cardiopulmonary bypass time was 78.39±25.12 minutes. The amount of heparin consumed by the second group was higher (P <0.001) which could be considered as an important factor in increasing the drainage time after the surgery (P =0.047). The pain level evaluated 24 hours post-operation was lower in the first group, and the difference in the pain level between the 2 groups evaluated 30 hours post-operation was significant (P=0.016). The mean time of intensive care unit stay was longer in the second group but it was not statistically significant. Early extracting of chest tubes after coronary artery bypass graft surgery when there is no significant drainage can lead to pain reduction and consuming oxygen is an effective measure after surgery toward healing; it doesn't increase the risk of creation of plural effusion and pericardial effusion.

We assess whether an initiative to optimize out-of-hospital provider cardiopulmonary resuscitation (CPR) quality is associated with improved CPR quality and increased survival from out-of-hospital cardiac arrest. This was a before-after study of consecutive adult out-of-hospital cardiac arrest. Data were obtained from out-of-hospital forms and defibrillators. Phase 1 included 18 months with real-time audiovisual feedback disabled (October 2008 to March 2010). Phase 2 included 16 months (May 2010 to September 2011) after scenario-based training of 373 professional rescuers and real-time audiovisual feedback enabled. The effect of interventions on survival to hospital discharge was assessed with multivariable logistic regression. Multiple imputation of missing data was used to analyze the effect of interventions on CPR quality. Analysis included 484 out-of-hospital cardiac arrest patients (phase 1 232; phase 2 252). Median age was 68 years (interquartile range 56-79); 66.5% were men. CPR quality measures improved significantly from phase 1 to phase 2: Mean chest compression rate decreased from 128 to 106 chest compressions per minute (difference -23 chest compressions; 95% confidence interval [CI] -26 to -19 chest compressions); mean chest compression depth increased from 1.78 to 2.15 inches (difference 0.38 inches; 95% CI 0.28 to 0.47 inches); median chest compression fraction increased from 66.2% to 83.7% (difference 17.6%; 95% CI 15.0% to 20.1%); median preshock pause decreased from 26.9 to 15.5 seconds (difference -11.4 seconds; 95% CI -15.7 to -7.2 seconds), and mean ventilation rate decreased from 11.7 to 9.5/minute (difference -2.2/minute; 95% CI -3.9 to -0.5/minute). All-rhythms survival increased from phase 1 to phase 2 (20/231, 8.7% versus 35/252, 13.9%; difference 5.2%; 95% CI -0.4% to 10.8%), with an adjusted odds ratio of 2.72 (95% CI 1.15 to 6.41), controlling for initial rhythm, witnessed arrest, age, minimally interrupted cardiac resuscitation protocol compliance, and provision of therapeutic hypothermia. Witnessed arrests/shockable rhythms survival was 26.3% (15/57) for phase 1 and 55.6% (20/36) for phase 2 (difference 29.2%; 95% CI 9.4% to 49.1%). Implementation of resuscitation training combined with real-time audiovisual feedback was independently associated with improved CPR quality, an increase in survival, and favorable functional outcomes after out-of-hospital cardiac arrest.

Bordetella pertussis is a gram-negative aerobic coccobacillus causing contagious respiratory tract disease called whooping cough. The virulence factors consist of pertussis toxin, filamentous hemagglutinin, fimbriae, lipooligosaccharide, and adenylate cyclase toxin. The disease causes a worldwide threat to public health despite a high vaccination coverage. The course of whooping cough in adults is frequently atypical, causing difficulty in diagnosis. In this report we present five patients hospitalized with Bordetella pertussis infection manifesting atypical and severe symptoms. The diagnosis was based on serological tests: serum concentration of specific antibodies against pertussis toxin and sputum cultures. We observed a wide spectrum of symptoms, from benign (sinus pain - 80 %, headaches - 20 %), through moderate (hemoptysis - 40 %; chest pain 60 %) to severe symptoms (cardiac arrhythmia - 40 %; syncope - 60 %). Bordetella pertussis infection can cause life-threatening complications and exacerbation of concomitant chronic diseases. Most vaccination programs cover only the first few months of life. Booster doses should be considered in adults, especially those immunocompromised or with pulmonary complications, but also in healthcare workers who are exposed to the contagion and also may spread the infection.

Objective We aimed to evaluate the limit of detection of high-sensitivity troponin (hs-cTn) and Thrombolysis In Myocardial Infarction (TIMI) score combination rule-out strategy suggested within the 2016 National Institute for Health and Care Excellence (NICE) Chest Pain of Recent Onset guidelines and establish the optimal TIMI score threshold for clinical use. Methods A pooled analysis of adult patients presenting to the emergency department with chest pain and a non-ischaemic ECG, recruited into six prospective studies, from Australia, New Zealand and the UK. We evaluated the sensitivity of TIMI score thresholds from 0 to 2 alongside hs-cTnT or hs-cTnI for the primary outcome of major adverse cardiac events within 30 days. Results Data were available for 3159 patients for hs-cTnT and 4532 for hs-cTnI, of these 376 (11.9%) and 445 (9.8%) had major adverse cardiac events, respectively. Using a TIMI score of 0, the sensitivity for the primary outcome was 99.5% (95% CI 98.1% to 99.9%) alongside hs-cTnT and 98.9% (97.4% to 99.6%)%) alongside hs-cTnI, identifying 17.9% and 21.0% of patients as low risk, respectively. For a TIMI score ≤1 sensitivity was 98.9% (97.3% to 99.7%)%) alongside hs-cTnT and 98.4% (96.8% to 99.4%)%) alongside hs-cTnI, identifying 28.1% and 35.7% as low risk, respectively. For TIMI≤2, meta-sensitivity was <98% with either assay. Conclusions Our findings support the rule-out strategy suggested by NICE. The TIMI score threshold suggested for clinical use is 0. The proportion of patients identified as low risk (18%–21%) and suitable for early discharge using this threshold may be sufficient to encourage change of practice.

Consecutive patients, aged ≥18, with suspected cardiac chest pain and non-ischaemic ECG, for whom the treating physician determined serial troponin testing was required. 30-day major adverse cardiac events (MACE). 960 participants were recruited. 912/960 (95.0%) had m-Goldman scores recorded by physicians and 745/960 (77.6%) by nursing staff. The area under the curve of the m-Goldman score in predicting 30-day MACE was 0.647 (95% CI 0.594 to 0.700) for physicians and 0.572 (95% CI 0.510 to 0.634) for nursing staff (p=0.09). When incorporated into an ADP, sensitivity for the rule-out of MACE was 99.2% (95% CI 94.8% to 100%) and 96.7% (90.3% to 99.2%) for physicians and nurses, respectively. One patient in the physician group (0.3%) and three patients (1.1%) in the nursing group were classified as low risk yet had MACE. There was fair agreement in the identification of low-risk patients (kappa 0.31, 95% CI 0.24 to 0.38). The diagnostic accuracy of ED nursing staff risk assessment is similar to that of ED physicians and interobserver reliability between assessor groups is fair. When incorporating high-sensitivity troponin testing, a nurse-led ADP has a miss rate of 1.1% for MACE at 30 days. Controlled Trials Database (ISRCTN no. 21109279).

Patients with chest pain of presumed esophageal origin should be reassured and should undergo an esophageal manometry study. In patients with spastic esophageal disorders, a trial with calcium channel blockers or low-dose antidepressants used as visceral analgesics is the best approach. Inpatients with non GERD-related, nonspastic esophageal motility disorder, low-dose antidepressants seem reasonable. Anxiolytics are useful in patients with panic disorders, and psychological interventions (eg, cognitive-behavioral therapy) are also valuable, mainly in patients in whom reassurance is not sufficient to avoid the misinterpretation of their symptoms. In the future, visceral sensitivity modifying agents such as serotoninergic agonists or antagonists may become the cornerstone of therapy in patients with chest pain of presumed esophageal origin. Combinations of different approaches, such as proton pump inhibitors and psychotropic or antinociceptive agents, should also be evaluated in clinical trials.

An elderly gentleman was successfully revived after undergoing cardiopulmonary resuscitation (CPR) for cardiac arrest. Post CPR, the patient developed acute pancreatitis which was likely complication of inappropriately delivered chest compressions which caused further complications and resulted in the death of the patient. This case underlines the importance of quality chest compressions that includes correct placement of hands by the operator giving chest compressions to avoid lethal injuries to the receiver.

Major trauma is the leading worldwide cause of death in young adults. The mortality from traumatic cardiac arrest remains high but survival with good neurological outcome from cardiopulmonary arrest following major trauma has been regularly reported. Rapid, effective intervention is required to address potential reversible causes of traumatic cardiac arrest if the victim is to survive. Current ILCOR guidelines do not contain a standard algorithm for management of traumatic cardiac arrest. We present a simple algorithm to manage the major trauma patient in actual or imminent cardiac arrest. We reviewed the published English language literature on traumatic cardiac arrest and major trauma management. A treatment algorithm was developed based on this and the experience of treatment of more than a thousand traumatic cardiac arrests by a physician - paramedic pre-hospital trauma service. The algorithm addresses the need treat potential reversible causes of traumatic cardiac arrest. This includes immediate resuscitative thoracotomy in cases of penetrating chest trauma, airway management, optimising oxygenation, correction of hypovolaemia and chest decompression to exclude tension pneumothorax. The requirement to rapidly address a number of potentially reversible pathologies in a short time period lends the management of traumatic cardiac arrest to a simple treatment algorithm. A standardised approach may prevent delay in diagnosis and treatment and improve current poor survival rates. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.
