    Introduction Quality of life measures are useful when interventions or treatments are indicated for several reasons such as improvement of physical functioning, pain relief, to estimate the effectiveness of therapies or to predict mortality. The aim of the current study was to describe quality of life in patients with stable coronary artery disease, myocardial infarction and heart failure and to evaluate the relationship between depression and health-related quality of life. Material and methods Patients after STEMI, with stable coronary artery disease, and heart failure (n = 332) completed the MacNew Heart Disease Health-related Quality of Life Questionnaire and the Hospital Anxiety and Depression Scale. Results Patients with myocardial infarction had significantly higher scores than patients with stable coronary artery disease or heart failure on the MacNew global scale (p < 0.001) and the physical (p < 0.001), emotional (p < 0.001) and social (p < 0.001) subscales. The anxiety scores were significantly higher in the group of patients with stable coronary artery disease than in patients with myocardial infarction (p < 0.05). The depression scores were significantly higher in patients with heart failure (p < 0.01). Conclusions In patients with stable CAD, anxiety correlated mainly with symptoms, i.e. angina, than with the history of MI. Patients with symptoms of angina react to the illness with anxiety more than depression, whereas patients with heart failure with dyspnea react to the illness with depressive symptoms more than anxiety. In patients after MI and with stable CAD, cognitive-behavioral techniques could be useful to quickly reduce the level of anxiety, while patients with heart failure require long-term support therapy to reduce the risk of depressive symptoms.

    Background Health-related quality of life (HRQL) assessment is an important measure of the impact of a wide range of disease process on an individual. To date, no HRQL tool has been evaluated in an Iranian population with cardiovascular disorders, specifically myocardial infarction, a major cause of mortality and morbidity. The MacNew Heart Disease Health-related Quality of Life instrument is a disease-specific HRQL questionnaire with satisfactory validity and reliability when applied cross-culturally. Method A Persian version of MacNew was prepared by both forward and backward translation by bilinguals after which a feasibility test was performed. Consecutive patients (n = 51) admitted to a coronary care unit with acute myocardial infarction were recruited for measurement of their HRQL with retest one month after discharge in the follow-up clinic. Principal components analysis, intra-class correlation reliability, internal consistency, and test-retest reliability were assessed. Results Trivial rates of missing data confirmed the acceptability of the tool. Principal component analysis revealed that the three domains, emotional, social and physical, performed as well as in the original studies. Internal consistency was high and comparable to other studies, ranging from 0.92 for the emotional and physical domains, to 0.94 for the social domain, and to 0.95 for the Global score. Domain means of 5, 5.3 and 4.9 for emotional, physical and social respectively indicate that our Iranian population has similar emotional and physical but worse social HRQL scores. Test-retest analysis showed significant correlation in emotional and physical domains (P < 0.05). Conclusion The Persian version of the MacNew questionnaire is comparable to the English version. It has high internal consistency and reasonable reproducibility, making it an appropriate specific quality of life tool for population-based studies and clinical practice in Iran in patients who have survived an acute

    Abstract Objective To determine the unadjusted and adjusted effects of income on heart disease; its main disease intermediary, high blood pressure; and its main behavioural risk factors, smoking and physical inactivity. Design Random-digit dialing telephone survey collected through the Canadian Community Health Survey by Statistics Canada. Setting Saskatchewan. Participants A total of 27 090 residents aged 20 years and older; each health region in Saskatchewan was represented. Main outcome measures Overall, 178 variables related to demographic characteristics, socioeconomic factors, behaviour, life stress, disease intermediaries, health outcomes, and access to health care were analyzed to determine their unadjusted and adjusted effects on heart disease. Results The mean age of the sample was 52.6 years. Women represented 55.9% of the sample. Most respondents were married (52.3%) and had some postsecondary or graduate education (52.5%). The mean personal income was $23 931 and the mean household income was $37 533. All models statistically controlled for age. Five covariates independently associated with heart disease included high blood pressure, household income of $29 999 or less per year, being a daily smoker, male sex, and being physically inactive. Five covariates independently associated with high blood pressure included being overweight or obese, being a daily smoker, household income of $29 999 or less per year, male sex, and being physically inactive. Five covariates independently associated with daily smoking included being a visible minority, household income of $29 999 or less per year, not being overweight or obese, education level of less than secondary school, and male sex. Six covariates independently associated with physical inactivity included being a visible minority, being overweight or obese, education level of less than secondary school, male sex, household income of $29 999 or less per year, and being a daily smoker.

    Cardiovascular diseases (CVDs) are the leading cause of mortality worldwide. Coronary heart disease (CHD) is the main cause of mortality in heart patients following stroke, rheumatic heart disease and myocardial infarctions. Approximately 80% of individuals succumb to CVDs, due to poor living conditions in low and middle income families and malnutrition. Infectious diseases, human immunodeficiency, tuberculosis, malaria, high blood pressure or hypertension, obesity and overweight, and nutritional disorders including smoking, excessive alcohol consumption, high salt and sugar intake, as well as other factors are responsible for CVDs and CHDs in young as well as elderly individuals. The focus of the present review are recent epidemiological aspects of CVD and CHD as well as the usefulness of a Mediterranean diet for heart patients and the prevention of heart diseases.

    Beri-beri heart disease is a distinctive clinical entity which must be distinguished from alcoholic cardiomyopathy and other forms of heart disease in chronic alcoholics. A 27-year-old man is described who for six months before the onset of symptoms of right heart failure—admitted to hospital with dyspnea and pitting edema in the lower limbs and over the sacrum—had lived over a tavern and consumed 24 pints of beer daily. The pathophysiology of beri-beri heart disease includes right heart failure, edema and peripheral vasodilatation in the muscular bed. These features were described by Wenckebach and others as early as 1928. Within the main entity, beri-beri heart disease, a number of sub-groups with special features and prognosis such as acute pernicious beri-beri have been described. Beri-beri heart disease is due to vitamin B1 deficiency and is curable if this deficiency is corrected in time. ImagesFig. 1Fig. 2aFig. 2b PMID:5940785

    Heart failure (HF) results from the impaired ability of heart to fill or pump out blood. HF is a common health problem with a multitude of causes and affects ~30 million people worldwide. Since ageing is a major risk factor for HF and as several treatment options are currently available to prolong the patients' survival, the number of affected patients is expected to grow. Even though traditional methods of assessment have been in use for managing HF, these are limited by time consuming and costly subjective interpretation and also by their invasive nature. Comparatively, biomarkers offer an objective and biologically relevant information that in conjunction with the patients' clinical findings provides optimal picture regarding the status of the HF patient and thus helps in diagnosis and prognosis. The current gold standard biomarkers for the diagnosis and prognosis of HF are B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP). Additional novel biomarkers (e.g., mid-regional pro atrial natriuretic peptide (MR-proANP), mid-regional pro adrenomedullin (MR-proADM), troponins, soluble ST2 (sST2), growth differentiation factor (GDF)-15 and galectin-3) can potentially identify different pathophysiological processes such as myocardial insult, inflammation and remodeling as the causes for the development and progression of HF. Different biomarkers of HF not only reflect the underlying mechanisms/pathways of HF and also its progression and also point specific therapy options. A multi-biomarker approach for personalized medical care is not too far fetched and such approach can greatly enhance diagnosis, prognostication, and therapy guidance for HF. In this review we describe the current status of HF biomarkers in clinical use and in laboratory research and the efforts aimed at the identification of novel biomarkers for HF. PMID:25339488

    Classical angina refers to typical substernal discomfort triggered by effort or emotions, relieved with rest or nitroglycerin. The well-accepted pathogenesis is an imbalance between oxygen supply and demand. Goals in therapy are improvement in quality of life by limiting the number and severity of attacks, protection against future lethal events, and measures to lower the burden of risk factors to slow disease progression. New pathophysiological data, drugs, as well as conceptual and technological advances have improved patient care over the past decade. Behavioral changes to improve diets, increase physical activity, and encourage adherence to cardiac rehabilitation programs, are difficult to achieve but are effective. PMID:26567972

  14. Endothelial mitochondria and heart disease.

    PubMed

    Davidson, Sean Michael

    2010-10-01

    The endothelium is vital to the proper functioning in the heart, in particular due to its production of nitric oxide (NO) which regulates vascular tone. Damage to the endothelium contributes to the development of atherosclerosis, and hence to possible myocardial infarction and subsequent heart failure. Like most cells, endothelial cells contain mitochondria, despite their having relatively little dependence on oxidative phosphorylation for ATP production. However, endothelial mitochondria are centrally involved in maintaining the fine regulatory balance between mitochondrial calcium concentration, reactive oxygen species (ROS) production, and NO. This raises the question of whether damage to endothelial mitochondria would have repercussions in terms of the development of heart disease. In fact, increasingly nuanced techniques enabling restricted transgenic expression of antioxidant proteins in mice has demonstrated that mitochondrial ROS do contribute to endothelial damage. New pharmaceutical approaches designed to target protective molecules such as ROS scavengers to the mitochondria promise to be effective in preventing heart disease. As well as protecting cardiomyocytes, these drugs may have the added benefit of preventing damage to the endothelial mitochondria. However, much remains to be done in understanding the contribution that mitochondria make to endothelial function. PMID:20558442

The world literature on the surgical treatment of echinococcosis of the heart is reviewed. Few cases are surgically treated, although the disease has been known for a long time. Localization to the liver and lungs is the most frequent. Cardiopulmonary bypass techniques make possible surgical treatment of hydatid cyst of the heart. The present paper is concerned with five cases operated upon between 1959 and 1969, three males and two females, their ages ranging from 13 to 46 years. A preoperative diagnosis was made in each case. One case was operated upon under cardiopulmonary bypass. The need for cardiopulmonary bypass on a stand-by basis is emphasized. The localization of the hydatid cyst was in the left ventricular wall (three cases), right ventricular wall (one case), and multiple (one case). The frequency of cardiac echinococcosis ranges between 0·5% and 2% according to various authors. Diagnosis is achieved with the aid of laboratory tests, radiology, and angiography; but the presence of the disease must be suspected in all patients who come from endemic areas. Surgical therapy is mandatory. Due to the growth characteristics of the cyst itself, the danger of damaging the ventricular wall at operation is increased; thus it is essential to have cardiopulmonary bypass facilities immediately available.

    Valvular heart disease (VHD) is caused by either damage or defect in one of the four heart valves, aortic, mitral, tricuspid or pulmonary. Defects in these valves can be congenital or acquired. Age, gender, tobacco use, hypercholesterolemia, hypertension, and type II diabetes contribute to the risk of disease. VHD is an escalating health issue with a prevalence of 2.5% in the United States alone. Considering the likely increase of the aging population worldwide, the incidence of acquired VHD is expected to increase. Technological advances are instrumental in identifying congenital heart defects in infants, thereby adding to the growing VHD population. Almost one-third of elderly individuals have echocardiographic or radiological evidence of calcific aortic valve (CAV) sclerosis, an early and subclinical form of CAV disease (CAVD). Of individuals ages >60, ~2% suffer from disease progression to its most severe form, calcific aortic stenosis. Surgical intervention is therefore required in these patients as no effective pharmacotherapies exist. Valvular calcium load and valve biomineralization are orchestrated by the concerted action of diverse cell-dependent mechanisms. Signaling pathways important in skeletal morphogenesis are also involved in the regulation of cardiac valve morphogenesis, CAVD and the pathobiology of cardiovascular calcification. CAVD usually occurs without any obvious symptoms in early stages over a long period of time and symptoms are identified at advanced stages of the disease, leading to a high rate of mortality. Aortic valve replacement is the only primary treatment of choice. Biomarkers such as asymmetric dimethylarginine, fetuin-A, calcium phosphate product, natriuretic peptides and osteopontin have been useful in improving outcomes among various disease states. This review, highlights the current understanding of the biology of VHD, with particular reference to molecular and cellular aspects of its regulation. Current clinical questions

    Critical congenital heart disease (CCHD) is a heart lesion for which neonates require early surgical intervention to survive. Without intervention, the rates of mortality and survival with significant disability are extremely high. Early diagnosis can potentially improve health outcomes in newborns with CCHD. Until recent years, no routine screening protocol existed. In the last few years, pulse oximetry screening for CCHD in newborns has been added to the list of recommended uniform screening panels and advocated by several health-care authorities. A positive screening test result warrants an echocardiogram to evaluate for CCHD. Newborn screens do not usually require parental consent. However, most of the states mandates in the United States include a statement allowing exemption from the screen on the basis of parental religious or personal beliefs. PMID:27390667

    The effects of "hypocirculation" and "hypercirculation" of the lungs are small. Hypocirculation has an influence of the ventilation/perfusion ratio, and can thus contribute to hypocapnia. In the early stages, hypercirculation--in particular via a left-to-right shung, leads to an increase in diffusion capacity; after a course of many years, a "counter-situation" occurs. Progressive pulmonary hypertension, as is exemplified for mitral stenosis, leads to measurable restrictive and obstructive impairment of function, and possible to unspecific hyper-reaction, as also, over the long-term, to a diminishement in membrane diffusion capacity. Chronic left heart failure is characterised by interstitial oedema at the level of the alveolar and bronchial capillary beds. The results are measurable restrictions in the static volumes, and in particular of the obstruction parameters and the closing volume that involve the small airways. In the individual case, no statement as to the extent of left heart failure is possible. In the passive pulmonary hypertension phase, diffusion capacity increases; in the further course of the disease, with development of interstitial and alveolar oedema, it decreases again. In acute left heart failure, the persistance and/or extent of pulmonary oedema is not determined solely by the magnitude of the pulmonary venous pressure. Permeability oedema--brought about by mediators--would appear to be significant on the basis of animal experiments. Not infrequently, left cardiac failure leads to small pleural effusions which occur in combination with substantial atelectasia, the aetiology of which is unclear. Interpretation difficulties are caused by the clinical findings and function-analytical data obtained in patients with a combination of chronic lung disease and reducted volume storage capacity of the pulmonary circulation and of the left heart failure, a common situation in the elderly patient. Diminished pulmonary function parameters that fail to

    Since the introduction of cardiac surgery, the prospects for children born with a cardiac defect have improved spectacularly. Many reach adulthood and the population of adults with congenital heart disease is increasing and ageing. However, repair of congenital heart disease does not mean cure. Many adults with congenital heart disease encounter late complications. Late morbidity can be related to the congenital heart defect itself, but may also be the consequence of the surgical or medical treatment or longstanding alterations in hemodynamics, neurodevelopment and psychosocial development. This narrative review describes the cardiac and non-cardiac long-term morbidity in the adult population with congenital heart disease. PMID:27451323

  6. Heart rate reduction in coronary artery disease and heart failure.

    PubMed

    Ferrari, Roberto; Fox, Kim

    2016-08-01

    Elevated heart rate is known to induce myocardial ischaemia in patients with coronary artery disease (CAD), and heart rate reduction is a recognized strategy to prevent ischaemic episodes. In addition, clinical evidence shows that slowing the heart rate reduces the symptoms of angina by improving microcirculation and coronary flow. Elevated heart rate is an established risk factor for cardiovascular events in patients with CAD and in those with chronic heart failure (HF). Accordingly, reducing heart rate improves prognosis in patients with HF, as demonstrated in SHIFT. By contrast, data from SIGNIFY indicate that heart rate is not a modifiable risk factor in patients with CAD who do not also have HF. Heart rate is also an important determinant of cardiac arrhythmias; low heart rate can be associated with atrial fibrillation, and high heart rate after exercise can be associated with sudden cardiac death. In this Review, we critically assess these clinical findings, and propose hypotheses for the variable effect of heart rate reduction in cardiovascular disease. PMID:27226153

    Heart development comprises myocyte specification, differentiation and cardiac morphogenesis. These processes are regulated by a group of core cardiac transcription factors in a coordinated temporal and spatial manner. Histone methylation is an emerging epigenetic mechanism for regulating gene transcription. Interplay among cardiac transcription factors and histone lysine modifiers plays important role in heart development. Aberrant expression and mutation of the histone lysine modifiers during development and in adult life can cause either embryonic lethality or congenital heart diseases, and influences the response of adult hearts to pathological stresses. In this review, we describe current body of literature on the role of several common histone methylations and their modifying enzymes in heart development, congenital and adult heart diseases.

    Heart failure (HF) is a growing public health concern as a consequence of the ageing of the population and the improved survival of patients with HF. HF is defined as impaired organ perfusion and/or high filling pressure. It is a systemic and chronic disease and as such involves many organs, not least the liver and kidney. The complex vascular system of the liver and its high metabolic activity render it vulnerable to circulation disturbances and trigger many molecular and haemodynamic changes in patients. There are many studies describing the impact of liver disease on patient outcomes. Hepatic dysfunction is commonly seen in HF patients and is closely correlated with a poor outcome. Knowledge about the mechanisms and impacts of liver disease in HF helps us to know the stage of the disease and treat it properly. Moreover, many drugs and toxins that are metabolised in the liver and contribute to drug interactions should also be taken into account when prescribing medication for HF patients. In light of the above-mentioned points, the authors have compiled this review on congestive hepatopathy with the aim of providing physicians and cardiologists with a succinct and useful guide on the role of the liver in HF.

    Pulmonary arterial hypertension in congenital heart disease (PAH-CHD) is a frequent complication in adults with congenital heart disease. Regardless of etiology, the optimal treatment strategy for this difficult population is challenging. The new frontier of targeted PAH therapies has demonstrated improved functional capacity in the various phenotypes of PAH-CHD, with work currently in progress scrutinizing outcomes. In those who fail conventional medical therapy, heart and heart-lung (block) transplantation become the final therapeutic options, with the role of ventricular assist devices and the total artificial heart still under investigation in this group.

  14. Indications for Heart Transplantation in Congenital Heart Disease

    PubMed Central

    2011-01-01

    In this review we have looked at indications for cardiac transplantation in congenital heart disease. An outline of the general principles of the use of transplant as a management strategy both as a first line treatment and following other surgical interventions is discussed. We explore the importance of the timing of patient referral and the evaluations undertaken, and how the results of these may vary between patients with congenital heart disease and patients with other causes of end-stage heart failure. The potential complications associated with patients with congenital heart disease need to be both anticipated and managed appropriately by an experienced team. Timing of transplantation in congenital heart disease is difficult to standardize as the group of patients is heterogeneous. We discuss the role and limitations of investigations such as BNP, 6 minute walk, metabolic exercise testing and self estimated physical functioning. We also discuss the suitability for listing. It is clear that congenital heart patients should not be considered to be at uniform high risk of death at transplant. Morbidity varies greatly in the congenital patient population with the failing Fontan circulation having a far higher risk than a failing Mustard circulation. However the underlying issue of imbalance between donor organ supply and demand needs to be addressed as transplant teams are finding themselves in the increasingly difficult situation of supporting growing numbers of patients with a diverse range of pathologies with declining numbers of donor organs.

    PubMed

    Schaefer, Ernst J

    2002-02-01

    This article reviews the current status of our knowledge of lipoproteins, nutrition, and coronary heart disease (CHD). Special emphasis is placed on CHD risk assessment, dietary intervention studies, diet-gene interactions, and current dietary guidelines and the contributions of my laboratory to these areas. CHD remains a major cause of death and disability, and risk factors include age, sex, hypertension, smoking, diabetes, elevated serum LDL cholesterol, and low HDL cholesterol. Emerging independent risk factors include elevated serum concentrations of lipoprotein(a), remnant lipoproteins, and homocysteine. The cornerstone of CHD prevention is lifestyle modification. Dietary intervention studies support the concepts that restricting saturated fat and cholesterol and increasing the intake of essential fatty acids, especially n - 3 fatty acids, reduces CHD risk. The variability in LDL-cholesterol response to diet is large, related in part to APOE and APOA4 genotype. The use of antioxidants in intervention studies has not been shown to reduce CHD risk. Compliance with dietary recommendations remains a major problem, and directly altering the food supply may be the most effective way to ensure compliance. The available data indicate that the recommendation to use fats, oils, and sugars sparingly for CHD prevention should be modified to a recommendation to use animal, dairy, and hydrogenated fats; tropical oils; egg yolks; and sugars sparingly and to increase the use of vegetables, fruit, and whole grains.

  1. Coronary heart disease at altitude.

    PubMed Central

    Alexander, J K

    1994-01-01

    In the past, it has been assumed that some basic physiologic responses to altitude, exposure in coronary patients are comparable to those in normal young subjects. In fact there are similar changes in sympathetic activation, heart rate, and blood pressure early after ascent, with decrements in plasma volume, cardiac output, and stroke volume as acclimatization proceeds. These responses are described, and experience with coronary patients is reviewed. During the 1st 2 to 3 days at altitude, coronary patients are at greatest risk of untoward events. Gradual rather than abrupt ascent, a moderate degree of physical conditioning, early limitation of activity to a level tolerated at low altitude for somewhat less), and attention to blood pressure control all appear to have protective effects. Ascent to moderate altitude appears to entail little risk in coronary patients who are asymptomatic or have moderate exercise tolerance, provided that the above precautions are observed and that activity does not exceed levels at lower altitude. If activity is to be increased, pre-ascent treadmill exercise testing or Holter monitor data secured under conditions comparable to those anticipated at altitude may provide reasonable guidelines. For coronary patients previously evaluated and known to be in a high-risk category, indications for ascent should be examined more critically, and precautionary measures should be more rigorous. Advice for patients with known coronary disease who may desire to trek at very high altitude must involve individual evaluation, and guidelines remain elusive. PMID:7888800

    2012-01-01

    Ischaemic heart disease (IHD) in pregnancy, particularly myocardial infarction (MI), is a rare yet potentially fatal condition for the mother and the foetus. With delays in the age of conception, the changes in some social habits among females including cigarette and shisha smoking in addition to an increased prevalence of diabetes mellitus, IHD may represent a real hazard among pregnant women in the near future. The difficulty in the diagnosis emerges from the similarity of the signs and symptoms of ischaemia and infarct to some of the physiological adaptations that occur in a normal pregnancy. The physiological changes that are normal in pregnancy may aggravate pre-existing disease and may unmask some underlying unrecognized coronary vascular changes; therefore, the diagnosis requires a high index of suspicion and careful assessment of the underlying risk factors. The management of IHD always requires a multidisciplinary team approach. The management of each patient should be individualized according to the clinical condition, the risk factors, and the availability of the necessary support. Pregnancy after MI may be an acceptable and reasonably safe option provided the cited criteria are met. A systematic PubMed search was performed to identify all published data including cases reports, small series and systematic reviews in the existing literature. These publications were comprised of both retrospective and cross sectional population studies to maximize the number of cases considered in order to reach conclusions and make recommendations based on the best available evidence considering the rare occurrence of this event. The epidemiology, diagnosis, medical and surgical treatment, and prognosis of IHD in pregnancy are the subjects of the present review. PMID:23960678

    The relationships between two behavioral patterns, cardiac risk factors, and coronary heart disease are investigated. Risk factors used in the analysis were family history of coronary disease, smoking, cholesterol, obesity, systotic blood pressure, diastolic blood pressure, blood sugar, uric acid, erythrocyte sedimentation rate, and white blood unit. It was found that conventional, non-behavioral pattern risk factors alone were not significantly related to coronary heart disease.

  4. The MacNew Questionnaire Is a Helpful Tool for Predicting Unplanned Hospital Readmissions After Coronary Revascularization

    2016-01-01

    Background The MacNew questionnaire is a neuro-behavioral tool which is easy and immediately usable. This self-reported questionnaire filled out by the patient allows the physician to achieve helpful information concerning the ways for optimizing the therapy and patient’s lifestyles. In this retrospective study, our aim was to assess whether relatively high scores found using the MacNew questionnaire in patients who had undergone percutaneous or surgical revascularization were associated with a decreased risk of unscheduled hospitalizations during the follow-up. Methods A retrospective analysis concerning 210 patients was carried out. The clinical sheets of these patients were examined as regards the information provided in the specific questionnaires (MacNew Italian version) routinely administered during the hospitalization prescribed for recovering from recent interventions of coronary percutaneous or surgery revascularization. Every patient undergoing the psychological test with MacNew questionnaire was followed up for 3 years. Results Using univariate analysis, a global score’s high value (i.e., above the median of the whole examined population) was shown to be associated with a significantly decreased risk of rehospitalization (HR (hazard ratio): 0.4312; 95% CI: 0.3463 - 0.5370; P < 0.0001). After adjustment for age, gender and myocardial infarction as initiating event, using a multivariate Cox proportional hazards regression model, the protection exerted by a high MacNew score against the risk of hospitalizations remained significant (HR: 0.0885; 95% CI: 0.0317 - 0.2472; P < 0.0001). Conclusions A relatively elevated MacNew global score appears to be associated with a significantly decreased risk of unscheduled hospitalizations after coronary revascularization over a 3-year follow-up.

    2014-01-01

    In patients with end-stage heart failure (HF), a total artificial heart (TAH) may be implanted as a bridge to cardiac transplant. However, in congenital heart disease (CHD), the malformed heart presents a challenge to TAH implantation. In the case presented here, a 17 year-old patient with congenital transposition of the great arteries (CCTGA) experienced progressively worsening HF due to his congenital condition. He was hospitalized multiple times and received an implantable cardioverter defibrillator (ICD). However, his condition soon deteriorated to end-stage HF with multisystem organ failure. Due to the patient's grave clinical condition and the presence of complex cardiac lesions, the decision was made to proceed with a TAH. The abnormal arrangement of the patient's ventricles and great arteries required modifications to the TAH during implantation. With the TAH in place, the patient was able to return home and regain strength and physical well-being while awaiting a donor heart. He was successfully bridged to heart transplantation 5 months after receiving the device. This report highlights the TAH is feasible even in patients with structurally abnormal hearts, with technical modification. PMID:25078059

    Due to the demographic change, chronic valvular heart disease becomes increasingly important - especially age-related primary diseases of the aortic and mitral valve as well as secondary diseases of the mitral and tricuspid valve caused by other age-related cardiac disorders. Medical treatment is limited to symptom relief by use of diuretics. Specific drugs or drugs with a prognostic benefit are not available. Thus, valve repair or replacement are the key options for treatment of relevant valvular heart disease. While open heart surgery was the only approach for a long time, interventional, catheter-based therapies have evolved in the last decade. This article describes up-to-date recommendations on indications for surgery for the most prevalent valvular heart diseases in adults - aortic stenosis, and aortic, mitral and tricuspid regurgitation).

    Only those congenital defects carrying a very low risk of complication (either before or after surgical correction) were considered. Atrial Septal Defects--(a) Ostium primum defects should be treated with caution either before or after surgical correction because of the risk of progressive conduction disorders and mitral regurgitation. (b) Ostium secundum defects could be considered for licensing (if the defect is small) or with surgical repair if the right ventricular systolic pressure is normal. (c) Sinus venosus defects--if too small to require surgical repair, licensing may be considered provided ambulatory electrocardiographic monitoring shows no evidence of arrhythmias. Surgery increases the risk of sino-atrial disease, thus licensing should be permitted only where there is no evidence of arrhythmia and adequate cardiological follow-up is possible. Ventricular Septal Defects--Subjects with very small defects not requiring surgical closure may be considered for licensing. Subjects who have had surgical closure have a risk of arrhythmias and should be carefully evaluated. Pulmonary Stenosis--If mild (either before or after surgery) may be licensed, but regular assessment perhaps including right heart catheterization is needed to demonstrate stability of the lesion. Persistent Ductus Arteriosus--Surgical closure should be recommended on diagnosis and need not affect licensing. Isolated Bicuspid Aortic Valve--Need not debar from licensing, but careful annual examination (with electrocardiogram 2-D echocardiography and fluroscopy ) is required to detect calcification, stenosis or regurgitation. Coarctation of aorta--Subjects who have had a repair before the age of 12 years may be considered for licensing after examination of other risk factors (blood pressure at rest and on exercise in particular). Those repaired over the age of 12 may be considered for restricted licensing if normotensive. These recommendations will need review in the light of further long

    There is growing evidence that the immune response is involved in atherosclerosis. Studies done over the past several years have shown an association between markers of inflammation and coronary atherosclerosis with an exacerbation of the inflammatory process during acute myocardial ischemia. Overall, these data have greatly renewed interest in the infectious theory of atherosclerosis and coronary heart disease. Search of bibliographic databases (from January 1991 through December 1999) and manual scanning of both peer-reviewed publications and other documents were used to identify pertinent literature. Infections and coronary heart disease were indexed as key words. A large number of studies have reported an association of human coronary heart disease and certain persistent bacterial and viral infections. The association between Chlamydia pneumoniae and coronary heart disease appears quite significant although the sequence of infection and disease is uncertain. The association between Helicobacter pylori and coronary heart disease may be accounted for by residual confounding from classic risk factors. Preliminary findings indicate that this association could be due to a higher prevalence of more virulent Helicobacter strains. Infection with Cytomegalovirus appears to be associated with a greater risk of restenosis after angioplasty rather than primary atherosclerosis. Early trials of appropriate antibiotic therapy in subjects with recent acute myocardial infarction have been encouraging. A causal relationship between infections and coronary heart disease is still elusive. Improved studies involving prospective collection of data are required to demonstrate such an association with potential implications for public health worldwide. PMID:10920505

    Khairy, Paul; Balaji, Seshadri

    2009-01-01

    Arrhythmias figure prominently among the complications encountered in the varied and diverse population of patients with congenital heart disease, and are the leading cause of morbidity and mortality. The incidence generally increases as the patient ages, with multifactorial predisposing features that may include congenitally malformed or displaced conduction systems, altered hemodynamics, mechanical or hypoxic stress, and residual or postoperative sequelae. The safe and effective management of arrhythmias in congenital heart disease requires a thorough appreciation for conduction system variants, arrhythmia mechanisms, underlying anatomy, and associated physiology. We, therefore, begin this review by presenting the scope of the problem, outlining therapeutic options, and summarizing congenital heart disease-related conduction system anomalies associated with disorders of the sinus node and AV conduction system. Arrhythmias encountered in common forms of congenital heart disease are subsequently discussed. In so doing, we touch upon issues related to risk stratification for sudden death, implantable cardiac devices, catheter ablation, and adjuvant surgical therapy. PMID:19898654

    Chagas disease, caused by the parasite Trypanosoma cruzi, is an important cause of cardiac disease in endemic areas of Latin America. It is now being diagnosed in non-endemic areas due to immigration. Typical cardiac manifestations of Chagas disease include dilated cardiomyopathy, congestive heart failure, arrhythmias, cardioembolism and stroke. Clinical and laboratory-based research to define the pathology resulting from T. cruzi infection has shed light on many of the cellular and molecular mechanisms leading to these manifestations. Antiparasitic treatment may not be appropriate for patients with advanced cardiac disease. Clinical management of Chagas heart disease is similar to that used for cardiomyopathies due to other processes. Cardiac transplantation has been successfully performed in a small number of patients with Chagas heart disease. PMID:22293860

    PubMed Central

    Zhu, Hongxin; Rothermel, Beverly A.; Hill, Joseph A.

    2009-01-01

    The heart is a highly plastic organ capable of remodeling in response to changes in physiological or pathological demand. When workload increases, the heart compensates through hypertrophic growth of individual cardiomyocytes to increase cardiac output. However, sustained stress, such as occurs with hypertension or following myocardial infarction, triggers changes in sarcomeric protein composition and energy metabolism, loss of cardiomyocytes, ventricular dilation, reduced pump function, and ultimately heart failure. It has been known for some time that autophagy is active in cardiomyocytes, occurring at increased levels in disease. Yet the potential contribution of cardiomyocyte autophagy to ventricular remodeling and disease pathogenesis has only recently been explored. This latter fact stems largely from the recent emergence of tools to probe molecular mechanisms governing cardiac plasticity and to define the role of autophagic flux in the context of heart disease. In this chapter, we briefly review prominent mouse models useful in the study of load-induced heart disease and standard techniques used to assess whether a molecular or cellular event is adaptive or maladaptive.

    2015-11-01

    In early stages, heart failure (HF) in adult congenital heart disease (ACHD) remains an elusive diagnosis. Many ACHD patients seem well-compensated owing to chronic physical and psychological adaptations. HF biomarkers and cardiopulmonary exercise tests are often markedly abnormal, although patients report stable health and good quality of life. Treatment differs from acquired HF. Evidence for effective drug therapy in ACHD-related HF is lacking. Residual ventricular, valvular, and vascular abnormalities contribute to HF pathophysiology, leading to an emphasis on nonpharmacologic treatment strategies. This article reviews emerging perspectives on nonpharmacologic treatment strategies, including catheter-based interventions, surgical correction, and palliative care. PMID:26471822

    In patients with congenital heart disease, the right heart may support the pulmonary or the systemic circulation. Several congenital heart diseases primarily affect the right heart including Tetralogy of Fallot, transposition of great arteries, septal defects leading to pulmonary vascular disease, Ebstein anomaly and arrhythmogenic right ventricular cardiomyopathy. In these patients, right ventricular dysfunction leads to considerable morbidity and mortality. In this paper, our objective is to review the mechanisms and management of right heart failure associated with congenital heart disease. We will outline pearls and pitfalls in the management of congenital heart disease affecting the right heart and highlight recent advances in the field. PMID:23483726

  10. Mitochondrial Dynamics in Heart Disease

    PubMed Central

    Dorn, Gerald W

    2012-01-01

    Mitochondrial fission and fusion have been observed, and their importance revealed, in almost every tissue and cell type except adult cardiac myocytes. As each human heart is uniquely dependent upon mitochondria to generate massive amounts of ATP that fuel its approximately 38 million contractions per year, it seems odd that cardiac myocytes are the sole exception to the general rule that mitochondrial dynamism is important to function. Here, I briefly review the mechanisms for mitochondrial fusion and fission and examine current data that dispel the previous notion that mitochondrial fusion is dispensable in the heart. Rare and generally overlooked examples of cardiomyopathies linked either to naturally-occurring mutations or to experimentally-induced mutagenesis of mitochondrial fusion/fission genes are described. New findings from genetically targeted Drosophila and mouse models wherein mitochondrial fusion deficiency has specifically been induced in cardiac myocytes are discussed. PMID:22450031

  11. Genetic Syndromes associated with Congenital Heart Disease

    PubMed Central

    2015-01-01

    Recent research has demonstrated that genetic alterations or variations contribute considerably to the development of congenital heart disease. Many kinds of genetic tests are commercially available, and more are currently under development. Congenital heart disease is frequently accompanied by genetic syndromes showing both cardiac and extra-cardiac anomalies. Congenital heart disease is the leading cause of birth defects, and is an important cause of morbidity and mortality during infancy and childhood. This review introduces common genetic syndromes showing various types of congenital heart disease, including Down syndrome, Turner syndrome, 22q11 deletion syndrome, Williams syndrome, and Noonan syndrome. Although surgical techniques and perioperative care have improved substantially, patients with genetic syndromes may be at an increased risk of death or major complications associated with surgery. Therefore, risk management based on an accurate genetic diagnosis is necessary in order to effectively plan the surgical and medical management and follow-up for these patients. In addition, multidisciplinary approaches and care for the combined extra-cardiac anomalies may help to reduce mortality and morbidity accompanied with congenital heart disease. PMID:26413101

    Objective To investigate the prevalence, characteristics and maternal and perinatal outcomes of pregnancies complicated by heart disease. Design Prospective single-centre registry. Setting Tertiary care teaching hospital in eastern Nepal. Patients Pregnant women presenting to the antenatal clinic and/or labour room between 1 March 2012 and 31 March 2013. Main outcome measures Prevalence, characteristics, and maternal and perinatal outcomes of pregnancies complicated by heart disease. Results Fifty-three out of 9463 pregnancies (0.6%) were complicated by cardiac disease. Proportions of acquired, congenital and arrhythmic heart disease amounted to 89%, 9% and 2%, respectively. Rheumatic heart disease (RHD) was the most frequent cardiac disease complicating pregnancy (n=47). Among 45 women with RHD continuing pregnancy until delivery, 30 (67%) were primigravidae. The predominant valvular pathology was mitral stenosis (62%), followed by mitral regurgitation (21%) and aortic regurgitation (13%). Twenty women (44%) underwent elective or emergency caesarean section. Maternal and fetal/perinatal mortality of pregnancies complicated by RHD amounted to 4% and 16%, respectively. New York Heart Association (NYHA) functional class III or class IV (HR 6.0, 95% CI 1.2 to 29.1, p=0.026), pulmonary hypertension (HR 9.1, 95% CI 1.6 to 51.5, p=0.012) and severe mitral stenosis (HR 7.0, 95% CI 1.4 to 34.4, p=0.017) were identified as predictors of maternal or fetal/perinatal mortality in an univariate analysis. Conclusions Rheumatic mitral stenosis was the most frequent heart disease complicating pregnancy in a consecutive cohort from a teaching hospital in Nepal. Exercise intolerance, pulmonary hypertension and severe mitral stenosis were identified as predictors of maternal or fetal/perinatal mortality. PMID:27326158

    It has recently been proposed that heart failure is a risk factor for Alzheimer′s disease. Decreased cerebral blood flow and neurohormonal activation due to heart failure may contribute to the dysfunction of the neurovascular unit and cause an energy crisis in neurons. This leads to the impaired clearance of amyloid beta and hyperphosphorylation of tau protein, resulting in the formation of amyloid beta plaques and neurofibrillary tangles. In this article, we will summarize the current understanding of the relationship between heart failure and Alzheimer′s disease based on epidemiological studies, brain imaging research, pathological findings and the use of animal models. The importance of atherosclerosis, myocardial infarction, atrial fibrillation, blood pressure and valve disease as well as the effect of relevant medications will be discussed. PMID:25041352

    Heart valve disease is a clinical problem that has been studied with classical imaging techniques like echocardiography and MRI. Technological advances in CT make it possible to obtain static and dynamic images that enable not only a morphological but also a functional analysis in many cases. Although it is currently indicated only in patients with inconclusive findings at echocardiography and MRI or those in whom these techniques are contraindicated, multidetector CT makes it possible to diagnose stenosis or regurgitation through planimetry, to evaluate and quantify valvular calcium, and to show the functional repercussions of these phenomena on the rest of the structures of the heart. Given that multidetector CT is being increasingly used in the diagnosis of ischemic heart disease, we think it is interesting for radiologists to know its potential for the study of valvular disease.

  16. Cardiac telocytes in normal and diseased hearts.

    PubMed

    Kostin, Sawa

    2016-07-01

    Our previous studies suggested that an important variable of the progression of contractile dysfunction to terminal heart failure is the imbalance between myocyte cell death and myocyte renewal. For this reason, preventing myocyte cell death and an increasing generation of new myocytes may represent attractive targets in the treatment of human heart failure. Prospective clues to enhance myocardial regeneration are the newly discovered cells termed telocytes, formerly called interstitial Cajal-like cells, which are believed to nurse or guide the endogenous and exogenous stem cells for activation and commitment, but they also act as supporting cells for progenitor cells migration toward injured myocardium. We have recently found that telocytes are reduced in the diseased and failing myocardium. Importantly, the imbalance between telocyte proliferation and telocyte death is responsible for the telocytes depletion in cardiac diseases leading to heart failure. We have also demonstrated that telocytes are influenced by the extracellular matrix protein composition such that the telocytes are almost absent in areas of severe fibrosis. It is plausible that the reduction in telocytes in diseased human hearts could participate in the abnormal three-dimensional spatial organization and disturbed intercellular signalling of the myocardium. Decreased telocytes in diseased hearts would also be predicted to alter the property of telocytes to maintain cardiac stem cell niche by decreasing the pool of cardiac stem cells and thereby impairing cardiac regeneration.

  17. Functional Assessment for Congenital Heart Disease

    PubMed Central

    2014-01-01

    Significant improvement in survival of children with congenital cardiac malformations has resulted in an increasing population of adolescent and adult patients with congenital heart disease. Of the long-term cardiac problems, ventricular dysfunction remains an important issue of concern. Despite corrective or palliative repair of congenital heart lesions, the right ventricle, which may be the subpulmonary or systemic ventricular chamber, and the functional single ventricle are particularly vulnerable to functional impairment. Regular assessment of cardiac function constitutes an important aspect in the long-term follow up of patients with congenital heart disease. Echocardiography remains the most useful imaging modality for longitudinal monitoring of cardiac function. Conventional echocardiographic assessment has focused primarily on quantification of changes in ventricular size and blood flow velocities during the cardiac cycles. Advances in echocardiographic technologies including tissue Doppler imaging and speckle tracking echocardiography have enabled direct interrogation of myocardial deformation. In this review, the issues of ventricular dysfunction in congenital heart disease, conventional echocardiographic and novel myocardial deformation imaging techniques, and clinical applications of these techniques in the functional assessment of congenital heart disease are discussed.

    This article presents the most relevant developments in 2013 in 3 key areas of cardiology: congenital heart disease, clinical cardiology, and heart failure and transplant. Within the area of congenital heart disease, we reviewed contributions related to sudden death in adult congenital heart disease, the importance of specific echocardiographic parameters in assessing the systemic right ventricle, problems in patients with repaired tetralogy of Fallot and indication for pulmonary valve replacement, and confirmation of the role of specific factors in the selection of candidates for Fontan surgery. The most recent publications in clinical cardiology include a study by a European working group on correct diagnostic work-up in cardiomyopathies, studies on the cost-effectiveness of percutaneous aortic valve implantation, a consensus document on the management of type B aortic dissection, and guidelines on aortic valve and ascending aortic disease. The most noteworthy developments in heart failure and transplantation include new American guidelines on heart failure, therapeutic advances in acute heart failure (serelaxin), the management of comorbidities such as iron deficiency, risk assessment using new biomarkers, and advances in ventricular assist devices.

    In this paper, we propose a method for automated screening of congenital heart diseases in children through heart sound analysis techniques. Our method relies on categorizing the pathological murmurs based on the heart sections initiating them. We show that these pathelogical murmur categories can be identified by examining the heart sound energy over specific frequency bands, which we call, Arash-Bands. To specify the Arash-Band for a category, we evaluate the energy of the heart sound over all possible frequency bands. The Arash-Band is the frequency band that provides the lowest error in clustering the instances of that category against the normal ones. The energy content of the Arash-Bands for different categories constitue a feature vector that is suitable for classification using a neural network. In order to train, and to evaluate the performance of the proposed method, we use a training data-bank, as well as a test data-bank, collectively consisting of ninety samples (normal and abnormal). Our results show that in more than 94% of cases, our method correctly identifies children with congenital heart diseases. This percentage improves to 100%, when we use the Jack-Knife validation method over all the 90 samples. PMID:18718691

  20. Autoimmune Pathogenesis of Chagas Heart Disease

    2016-01-01

    Chagas heart disease is an inflammatory cardiomyopathy that develops in approximately one-third of individuals infected with the protozoan parasite Trypanosoma cruzi. Since the discovery of T. cruzi by Carlos Chagas >100 years ago, much has been learned about Chagas disease pathogenesis; however, the outcome of T. cruzi infection is highly variable and difficult to predict. Many mechanisms have been proposed to promote tissue inflammation, but the determinants and the relative importance of each have yet to be fully elucidated. The notion that some factor other than the parasite significantly contributes to the development of myocarditis was hypothesized by the first physician-scientists who noted the conspicuous absence of parasites in the hearts of those who succumbed to Chagas disease. One of these factors—autoimmunity—has been extensively studied for more than half a century. Although questions regarding the functional role of autoimmunity in the pathogenesis of Chagas disease remain unanswered, the development of autoimmune responses during infection clearly occurs in some individuals, and the implications that this autoimmunity may be pathogenic are significant. In this review, we summarize what is known about the pathogenesis of Chagas heart disease and conclude with a view of the future of Chagas disease diagnosis, pathogenesis, therapy, and prevention, emphasizing recent advances in these areas that aid in the management of Chagas disease.

    While a considerable literature has emerged regarding the relationship between the business cycles and mortality rates, relatively little is known regarding how economic fluctuations are related to morbidity. We investigate the relationship between business cycles and heart disease in Mexico using a unique state-level dataset of 512 observations consisting of real GDP and heart disease incidence rates (overall and by age group) from 1995 to 2010. Our study is one of the first to use a state-level panel approach to analyze the relationship between the business cycle and morbidity. Further, the state and year fixed effects employed in our econometric specification reduce possible omitted variable bias. We find a general procyclical, although largely statistically insignificant, contemporaneous relationship. However, an increase in GDP per capita sustained over five years is associated with considerable increases in the incidence rates of ischemic heart disease and hypertension. This procyclical relationship appears strongest in the states with the lowest levels of development and for the oldest age groups. Our results suggest that economic fluctuations may have important lagged effects on heart disease in developing countries. PMID:24681397

    Current pharmacologic therapy for ischemic heart disease suffers multiple limitations such as compliance issues and side effects of medications. Revascularization procedures often end with need for repeat procedures. Patients remain symptomatic despite maximal medical therapy. Gene therapy offers an attractive alternative to current pharmacologic therapies and may be beneficial in refractory disease. Gene therapy with isoforms of growth factors such as VEGF, FGF and HGF induces angiogenesis, decreases apoptosis and leads to protection in the ischemic heart. Stem cell therapy augmented with gene therapy used for myogenesis has proven to be beneficial in numerous animal models of myocardial ischemia. Gene therapy coding for antioxidants, eNOS, HSP, mitogen-activated protein kinase and numerous other anti apoptotic proteins have demonstrated significant cardioprotection in animal models. Clinical trials have demonstrated safety in humans apart from symptomatic and objective improvements in cardiac function. Current research efforts are aimed at refining various gene transfection techniques and regulation of gene expression in vivo in the heart and circulation to improve clinical outcomes in patients that suffer from ischemic heart disease. In this review article we will attempt to summarize the current state of both preclinical and clinical studies of gene therapy to combat myocardial ischemic disease. PMID:20600100

    In the year 2012, 3 scientific sections-heart failure and transplant, congenital heart disease, and clinical cardiology-are presented together in the same article. The most relevant development in the area of heart failure and transplantation is the 2012 publication of the European guidelines for heart failure. These describe new possibilities for some drugs (eplerenone and ivabradine); expand the criteria for resynchronization, ventricular assist, and peritoneal dialysis; and cover possibilities of percutaneous repair of the mitral valve (MitraClip(®)). The survival of children with hypoplastic left heart syndrome in congenital heart diseases has improved significantly. Instructions for percutaneous techniques and devices have been revised and modified for the treatment of atrial septal defects, ostium secundum, and ventricular septal defects. Hybrid procedures for addressing structural congenital heart defects have become more widespread. In the area of clinical cardiology studies have demonstrated that percutaneous prosthesis implantation has lower mortality than surgical implantation. Use of the CHA2DS2-VASc criteria and of new anticoagulants (dabigatran, rivaroxaban and apixaban) is also recommended. In addition, the development of new sequencing techniques has enabled the analysis of multiple genes. PMID:24775619

    The congenital heart disease includes abnormalities in heart structure that occur before birth. Such defects occur in the fetus while it is developing in the uterus during pregnancy. About 500,000 adults have congenital heart disease in USA (WebMD, Congenital heart defects medications, www.WebMD.com/heart-disease/tc/congenital-heart-defects-medications , 2014). 1 in every 100 children has defects in their heart due to genetic or chromosomal abnormalities, such as Down syndrome. The excessive alcohol consumption during pregnancy and use of medications, maternal viral infection, such as Rubella virus, measles (German), in the first trimester of pregnancy, all these are risk factors for congenital heart disease in children, and the risk increases if parent or sibling has a congenital heart defect. These are heart valves defects, atrial and ventricular septa defects, stenosis, the heart muscle abnormalities, and a hole inside wall of the heart which causes defect in blood circulation, heart failure, and eventual death. There are no particular symptoms of congenital heart disease, but shortness of breath and limited ability to do exercise, fatigue, abnormal sound of heart as heart murmur, which is diagnosed by a physician while listening to the heart beats. The echocardiogram or transesophageal echocardiogram, electrocardiogram, chest X-ray, cardiac catheterization, and MRI methods are used to detect congenital heart disease. Several medications are given depending on the severity of this disease, and catheter method and surgery are required for serious cases to repair heart valves or heart transplantation as in endocarditis. For genetic study, first DNA is extracted from blood followed by DNA sequence analysis and any defect in nucleotide sequence of DNA is determined. For congenital heart disease, genes in chromosome 1 show some defects in nucleotide sequence. In this review the causes, diagnosis, symptoms, and treatments of congenital heart disease are described

    The prevalence of coronary artery disease in female patients is increasing due to changing lifestyle patterns including cigarette smoking, diabetes and stress. Since women are delaying childbearing until older age, acute coronary syndrome will more frequently occur during pregnancy. Although rare, acute coronary syndrome during pregnancy often has devastating consequences. It is associated with increased maternal and neonatal mortality and morbidity compared with the nonpregnant situation. Furthermore, it constitutes an important problem for the patient and the treating physician, because the selection of diagnostic and therapeutic approaches is greatly influenced not only by maternal, but also by fetal safety.

    Heart disease is a leading cause of death in the United States, and hypertension is a predominant risk factor. Thus, effective blood pressure control is important to prevent adverse sequelae of hypertension, including heart failure, coronary artery disease, atrial fibrillation, and ischemic stroke. Over half of Americans have uncontrolled blood pressure, which may in part be explained by interpatient variability in drug response secondary to genetic polymorphism. As such, pharmacogenetic testing may be a supplementary tool to guide treatment. This review highlights the pharmacogenetics of antihypertensive response and response to drugs that treat adverse hypertension-related sequelae, particularly coronary artery disease and atrial fibrillation. While pharmacogenetic evidence may be more robust for the latter with respect to clinical implementation, there is increasing evidence of genetic variants that may help predict antihypertensive response. However, additional research and validation are needed before clinical implementation guidelines for antihypertensive therapy can become a reality. PMID:26272307

    Rates of acute rheumatic fever and chronic rheumatic heart disease in Aboriginal people, Torres Strait Islanders and Māori continue to be unacceptably high. The impact of rheumatic heart disease is inequitable on these populations as compared with other Australians and New Zealanders. The associated cardiac morbidity, including the development of rheumatic valve disease, and cardiomyopathy, with possible sequelae of heart failure, development of atrial fibrillation, systemic embolism, transient ischaemic attacks, strokes, endocarditis, the need for interventions including cardiac surgery, and impaired quality of life, and shortened life expectancy, has major implications for the individual. The adverse health and social effects may significantly limit education and employment opportunities and increase dependency on welfare. Additionally there may be major adverse impacts on family and community life. The costs in financial terms and missed opportunities, including wasted young lives, are substantial. Prevention of acute rheumatic fever is dependent on the timely diagnosis and treatment of sore throats and skin infections in high-risk groups. Both Australia and New Zealand have registries for acute rheumatic fever but paradoxically neither includes all cases of chronic rheumatic heart disease many of whom would benefit from close surveillance and follow-up. In New Zealand and some Australian States there are programs to give secondary prophylaxis with penicillin, but these are not universal. Surgical outcomes for patients with rheumatic valvular disease are better for valve repair than for valve replacement. Special attention to the selection of the appropriate valve surgery and valve choice is required in pregnant women. It may be necessary to have designated surgical units managing Indigenous patients to ensure high rates of surgical repair rather than valve replacement. Surgical guidelines may be helpful.

    2015-01-01

    Due to advances in paediatric congenital heart surgery, there are a growing number of women with congenital heart disease (CHD) reaching childbearing age. Pregnancy, however, is associated with haemodynamic stresses which can result in cardiac decompensation in women with CHD. Many women with CHD are aware of their cardiac condition prior to pregnancy, and preconception counselling is an important aspect of their care. Preconception counselling allows women to make informed pregnancy decisions, provides an opportunity for modifications of teratogenic medications and, when necessary, repair of cardiac lesions prior to pregnancy. Less commonly, the haemodynamic changes of pregnancy unmask a previously unrecognised heart lesion. In general, pregnancy outcomes are favourable for women with CHD, but there are some cardiac lesions that carry high risk for both the mother and the baby, and this group of women require care by an experienced multidisciplinary team. This review discusses preconception counselling including contraception, an approach to risk stratification and management recommendations in women with some common CHDs.

    Lifestyle modification is primary in cardiovascular (CV) disease prevention. A major contribution is the Mediterranean diet (MedDiet), defined by two of seven components. Italian investigators determined a significant decrease in peripheral arterial disease of 56 % for a high score. Multiple specific CV risk factors are also favorably modified by the MedDiet. This includes beneficial effect on inflammation, vascular endothelium, and insulin resistance. There is also evidence that coronary heart disease, diabetes mellitus, and metabolic syndrome are decreased. Benefit appears to extend to new migrants in France. The economics of dietary adherence are favorable with decreased total lifetime health costs.

Benefit also extends to other noncommunicable diseases with a decrease in cancer, Parkinson's disease, and Alzheimer's disease.

    Patients with adult congenital heart disease have an increased risk of developing pulmonary hypertension. There are several mechanisms of pulmonary hypertension in patients with adult congenital heart disease, and understanding them requires a systematic approach to define the patient's hemodynamics and physiology. This article reviews the updated classification of pulmonary hypertension in patients with adult congenital heart disease with a focus on pathophysiology, diagnostics, and the evaluation of pulmonary hypertension in special adult congenital heart disease populations.

    The amyloidoses represent a group of diseases characterized by extracellular deposition of abnormal protein, amyloid, which is formed by insoluble extracellular fibrils in β-pleated sheets. Although cardiac involvement may occur in all types of amyloidoses, clinically relevant amyloid cardiomyopathy is a typical feature of AL amyloidosis and transthyretin-related amyloidoses. Congestive heart failure represents the commonest manifestation of amyloid heart disease. Noninvasive imaging techniques, especially echocardiography and cardiac magnetic resonance, play a major role in the diagnosis of amyloid cardiomyopathy; however, histological confirmation and exact typing of amyloid deposits is necessary whether in extracardiac location or directly in the myocardium. Early diagnosis of amyloid heart disease is of utmost importance as the presence and especially the severity of cardiac involvement generally drives the prognosis of affected subjects and plays a major role in determining the intensity of specific treatment, namely in AL amyloidosis. The management of patients with amyloid heart disease is complex. Loop diuretics together with aldosterone antagonists represent the basis for influencing signs of congestion. In AL amyloidosis, high-dose chemotherapy followed by autologous stem cell transplantation is generally considered to be a front-line treatment option, if the disease is diagnosed at its early stage. The combination of mephalan with dexamethasone has been the standard therapy for severely affected individuals; however, the combinations with several novel agents including immunomodulatory drugs and bortezomibe have been tested in clinical trials with promising results. New therapeutic substances with the potential to slow or even stop the progression of transthyretin-related amyloidosis are also extensively studied. PMID:25483951

    An expectation for long-term survival has emerged among several groups of cancer patients treated with therapeutic irradiation (eg, Hodgkin's disease, early stage breast cancer). Therefore, the cardiovascular sequelae of thoracic irradiation have recently come under scrutiny. Animal models have demonstrated that cardiac irradiation can directly damage the myocardial microvasculature and can indirectly damage the coronary macrovasculature when coupled with cholesterol feeding. A clear association between thoracic radiotherapy and ischemic heart disease was observed among older clinical studies using radiotherapeutic techniques that are no longer optimal by today's standards. Such a relationship could not be confirmed in modern studies in which treatment factors (such as dose and volume of heart irradiated) were more carefully controlled. 56 references.

    Background: Coronary Heart Disease (CHD) is associated with emotions, especially negative ones, namely anxiety and depression. Emotional Intelligence (EI) is a psychological model that consists of a variety of emotional skills. Aims: The aim of the present study was to examine the relation between different dimensions of Emotional Intelligence and coronary heart disease. Methods: A total of 300 participants were studied during a 3-year period in an attempt to partially replicate and further expand a previous study conducted in Greece among CHD patients, which indicated a strong association between certain dimensions of Emotional Intelligence and the incidence of CHD. All participants completed a self-report questionnaire, assessing several aspects of Emotional Intelligence. Findings: The results showed that there is a link between the regulation of emotions and the occurrence of CHD. Conclusions: The evidence reported in the present study makes stronger the claim that EI plays a significant role in the occurrence of CHD. PMID:24171883

    Suboptimal intrauterine development has been linked to predisposition to cardiovascular disease in adulthood, a concept termed 'developmental origins of health and disease'. Although the exact mechanisms underlying this developmental programming are unknown, a growing body of evidence supports the involvement of epigenetic regulation. Epigenetic mechanisms such as DNA methylation, histone modifications and micro-RNA confer added levels of gene regulation without altering DNA sequences. These modifications are relatively stable signals, offering possible insight into the mechanisms underlying developmental origins of health and disease. This review will discuss the role of epigenetic mechanisms in heart development as well as aberrant epigenetic regulation contributing to cardiovascular disease. Additionally, we will address recent advances targeting epigenetic mechanisms as potential therapeutic approaches to cardiovascular disease. PMID:25572405

    In patients with heart valve disease, echocardiography is the mainstay for diagnosis, assessment and serial surveillance. However, other modalities, notably cardiac MRI and CT, are used if echocardiographic imaging is suboptimal but can also give complementary information to improve assessment of the valve lesion and cardiac compensation to aid the timing of surgery and determine risk. This statement discusses the way these imaging techniques are currently integrated to improve care beyond what is possible with echocardiography alone. PMID:26977308

    Three-dimensional imaging modalities for structural heart disease interventions have become a common feature in the procedural workflow. The images acquired are usually presented on 2D displays, thereby restricting their usefulness and the ability to interact with them. Holographic images created in real time from the volumetric data which float in the air during the procedure, in front of the operator and above the patient, could provide an intuitive and interactive display for the interventionalist and improve procedure outcomes.

    The clinical approach to adults with congenital heart diseases (ACHDs) is unique in cardiovascular medicine because these patients encompass a broad range of presentations. Each patient, despite having similar diagnosis, will be anatomically and physiologically unlike others within ACHD population, in relation to the type of repair, age at repair, associated defects, with specific long-term risk factors and complications. Furthermore, as many patients will not complain of symptoms, clinical evaluation and diagnostic testing must also be based on the underlying main diagnostic category, with complete standardized lesion-specific clinical protocols, investigating all known risk factors specific for each congenital heart disease and performed as part of screening for significant long-term complications. The first part of this review will focus on clinical history, physical examination, and the most important diagnostic testing in ACHD population. The second part of the article will focus on some clinical issues we have to face in our daily practice, such as heart failure, cyanosis, and pulmonary hypertension. Furthermore, as survival rates of ACHD population continue to improve and patients with this condition live longer, we will briefly report on a new clinical concern regarding the impact of acquired morbidities like coronary artery disease that appear to be of greater importance in defining outcome in older patients with ACHD.

    Among 407 patients with rheumatic heart disease studied in our department, we found 8.3% with coronary atherosclerosis: 2.7% with mitral stenosis and 2.4% with aortic stenosis, lower figures than those reported in the literature. In our patients with coronary atherosclerosis, the male to female ratio was 1.6:1. The mean age of men and women with coronary atherosclerosis were 58.9 +/- 8.48 years and 60.33 +/- 5.75 years respectively. The cumulated relative frequency curve of the age was shifted to the right in the patients with coronary atherosclerosis, compared with the age frequency curve of the patients with normal coronary arteries: 50% of the cases with coronary atherosclerosis were < or = 60 years old; on the other hand, 50% of the patients with normal coronary arteries were < 53 years old. We only discovered 3 patients younger than 50 years old with coronary atherosclerosis. In order of frequency, the coronary arteries more affected were the anterior descending, right and circumflex. The mean coronary stenosis was 75.2 +/- 21.2%. Disease of one vessel was observed more frequently. We believe that age is not a good parameter to indicate coronarography in patients with valvular heart disease. If coronarography would be performed in all patients with valvular disease > or = 30 or 40 years old, would result in a great number of normal studies, with the consequent misspend of supplies and the increased risk of complications. On the other hand, restricting the coronarography indication, would miss the diagnosis in patients that might need myocardial revascularization. To restrict or to increase the indication of coronarography in patients with valvular disease will depend of the frequency between rheumatic heart disease and associated coronary atherosclerosis, and also on the atherosclerosis risk factors present in each patient. We recommend not to use the age of the patients as an index to indicate coronarography. PMID:8768624

    Carcinoid heart disease is a major cause of morbidity and mortality in patients with metastatic neuroendocrine tumours (NETs). Although cases of carcinoid syndrome and severe carcinoid heart disease requiring urgent intervention are well described, many patients with significant carcinoid heart disease may have insidious symptoms or even be asymptomatic. As haemodynamically significant carcinoid heart disease may be clinically silent, specific and individualised considerations must be made as to the most appropriate clinical criteria and time point at which surgical valve replacement should be undertaken in patients with carcinoid heart disease.

    Vitamin D has been proposed as a risk factor of ischaemic heart disease. In 12 patients with acute myocardial infarction the major circulating vitamin D metabolite, 25-hydroxy-cholecalciferol (25-HCC), did not show any fluctuations during the first 4 days after onset of symptoms. The serum 25-HCC level was then measured in 128 patients consecutively admitted because of chest pain, 53 of whom had myocardial infarction and 75 had angina pectoris. The values found did not differ from those measured in 409 normal persons. The seasonal variations of serum 25-HCC were less pronounced in heart patients than in normals, probably due to less sun exposure in the summer months. The levels of serum 25-HCC did not correlate with the concentrations of serum cholesterol, glycerides, calcium or magnesium. Low serum calcium and magnesium were observed in all patients. Serum calcium was further reduced in the course of acute myocardial infarctions while serum parathyroid hormone rose significantly. We conclude that patients with ischaemic heart disease are not ingesting or producing in their skin elevated amount of vitamin D. PMID:744575

    Africa has one of the highest prevalence of heart diseases in children and young adults, including congenital heart disease (CHD) and rheumatic heart disease (RHD). We present here an extensive review of recent data from the African continent highlighting key studies and information regarding progress in CHD and RHD since 2005. Main findings include evidence that the CHD burden is underestimated mainly due to the poor outcome of African children with CHD. The interest in primary prevention for RHD has been recently re-emphasised, and new data are available regarding echocardiographic screening for subclinical RHD and initiation of secondary prevention. There is an urgent need for comprehensive service frameworks to improve access and level of care and services for patients, educational programmes to reinforce the importance of prevention and early diagnosis and a relevant research agenda focusing on the African context.

    Although the laser has been in existence for abut 30 years, its application in heart disease has only been examined in the past decade. Much attention has been given its exciting potential in treating coronary artery disease. Transmitted through a catheter comprised of one or more thin optical fibers which can be threaded nonsurgically into the coronary artery, the laser can ablate atherosclerotic plaque that obstructs the artery and diminishes blood flow to the myocardium. In clinical studies, the laser can treat some obstructive lesions that are not suitable for balloon angioplasty (i.e., long and diffuse lesions, very tight stenoses, ostial lesions, calcified lesions). In patients who failed balloon angioplasty due to severe dissection or abrupt closure, the laser may seal up the dissections and restore antegrade blood flow. In addition, the laser may have other applications and treatment modalities that are still under investigation. It may ablate ectopic ventricular foci, or terminate supraventricular tachyrhythmia by destroying the heart's abnormal conduction pathways. It can cut the hypertrophied septum that is associated with left ventricular outflow tract obstruction, or create a channel in the atrial septum as a palliative procedure in newborns with transposition of the great vessels. It may provide a wider orifice for blood flow within the heart in infants with pulmonary outflow obstruction and in adults with aortic valvular stenosis. It is also capable of fusing small thin-walled blood vessels together. Further, a more intriguing possibility is its use to bore several tiny channels in the myocardium to allow oxygenated blood from within the ventricular chamber to perfuse the ischemic heart tissue.

    Drug-induced valvular heart disease (DIVHD) was first described in the 1960s. Initially, associations with ergot derivatives used for migraine prevention, or with anorectic drugs, were described. Drugs used for the treatment of Parkinson's disease and endocrine diseases, like hyperprolactinemia, may also induce VHD. More recently, the use of 3,4-methylendioxymetamphetamine (MDMA, 'Ecstasy') and benfluorexhave been found to be associated with DIVHD. Although some of these drugs were withdrawn from the market, several cases of patients requiring valve surgery even years after the cessation of therapy have been reported. DIVHD is not infrequent, may be severe, and has been described in association with several drugs. Even after drug cessation, long-term implications of this type of VHD may persist. The present review underlines the need for a careful evaluation of the associated clinical and echocardiographic risk factors to allow early recognition so as not to delay appropriate management.

    This article provides an overview of work in two areas of biobehavioural research: the effects of environmental stress and the role of psychophysiologic reactivity in the development of ischaemic heart disease. Attention is given first to evidence that low socio-economic status, low social support, and occupational settings characterized by high demands and low levels of control over the job are associated with increased coronary risk. Also discussed is a promising animal primate model of social stress and its role in development of coronary atherosclerosis. Next, we discuss physiological responsiveness (reactivity) to emotional stress, which is being studied as a marker of processes involved in the development of cardiovascular disease. Stress and psychophysiological reactivity constitute promising targets for research on biobehavioural antecedents of coronary disease and for clinical intervention studies. However, further evidence is needed before these variables can be regarded as proven coronary risk factors. PMID:3129010

    Screening for critical congenital heart disease (CCHD) was added to the United States Recommended Uniform Screening Panel in 2011. Since that time, CCHD screening with pulse oximetry has become nearly universal for newborns born in the United States. There are various algorithms in use. Although the goal of the screening program is to identify children who may have CCHD, most newborns who have a low oxygen saturation will not have CCHD. Further study is needed to determine optimal guidelines for CCHD screening in special settings such as the neonatal intensive care unit, areas in high altitude, and home births. PMID:26876122

    Through the better understanding of the genetics and clinical associations of Primary Ciliary Dyskinesia (PCD), an autosomal recessive disorder of ciliary motility and mucociliary clearance, the association between PCD and heterotaxic congenital heart disease (CHD) has been established. In parallel, research into the cause of CHD has elucidated further the role of ciliary function on the development of normal cardiovascular structure. Increased awareness by clinicians regarding this elevated risk of PCD in patients with CHD will allow for more comprehensive screening and identification of cases in this high-risk group with earlier diagnosis leading to improved health outcomes.

    Macroreentrant atrial tachycardia is a common complication following surgery for congenital heart disease (CHD), and is often highly symptomatic with potentially significant hamodynamic consequences. Medical management is often unsuccessful, requiring the use of invasive procedures. Cavotricuspid isthmus dependent flutter is the most common circuit but atypical circuits also exist, involving sites of surgical intervention or areas of scar related to abnormal hemodynamics. Ablation can be technically challenging, due to complex anatomy, and difficulty with catheter stability. A thorough assessment of the pa-tients status and pre-catheter ablation planning is critical to successfully managing these patients. PMID:25308809

    An investigation of defects of the haemostatic mechanism in 41 children with cyanotic congenital heart disease concluded that such abnormalities were common and normally involved factors synthesised in the liver, that is the vitamin K dependent factors (rothrombin, factors VII and IX) and factor V. No evidence was found of activation of the coagulation or fibrinolytic systems. The defects can be explained by deficient synthesis resulting from systemic hypoxia as well as from sluggishness of the local microcirculation caused by high blood viscosity. Vitamin K parenterally had no demonstrable effect. Replacement of these factors, possibly combined with measures to improve the microcirculation, therefore, appears to be the appropriate treatment.

    OBJECTIVE: To determine the feasibility of studying myocardial and skeletal muscle bioenergetics using 31P magnetic resonance spectroscopy (MRS) in babies and young children with congenital heart disease. SUBJECTS: 16 control subjects aged 5 months to 24 years and 18 patients with CHD, aged 7 months to 23 years, of whom 11 had cyanotic CHD, five had cardiac failure, and two had had a Senning procedure. DESIGN: 31P MRS was carried out using a 1.9 Tesla horizontal 65 cm bore whole body magnet to study the myocardium in 10 patients and skeletal muscle (gastrocnemius) in 14 patients, eight of whom were exercised, together with appropriate controls. RESULTS: In hypoxaemic patients, in skeletal muscle at rest intracellular pH (pHi) was abnormally high [7.06 (SEM 0.04) v 7.04 (0.05), P < 0.01] and showed a positive correlation with haemoglobin (P < 0.03). On exercise, hypoxaemic patients fatigued more quickly but end-exercise pHi and phosphocreatine recovery were normal, implying that an equivalent but smaller amount of work had been performed. End-exercise ADP concentration was lower. On recovery, the initial rate of phosphocreatine resynthesis was low. Skeletal muscle bioenergetics were within normal limits in those in heart failure. In the myocardium, the phosphocreatine/ATP ratio was similar in controls and hypoxaemic subjects, but low in those in heart failure. CONCLUSIONS: In heart failure, the myocardial phosphocreatine/ATP ratio was reduced, as in adults, while resting skeletal muscle studies were normal. By contrast, hypoxaemic children had normal myocardial bioenergetics, but showed skeletal muscle alkalinity, and energy reserves were more readily depleted on exercise. On recovery, the initially slow phosphocreatine resynthesis rate reflects a low rate of mitochondrial ATP synthesis, probably due to an inadequate oxygen supply. 31P MRS offers a safe, non-invasive method of studying myocardial and skeletal muscle bioenergetics in children as young as 5 months

    An excessive oxidative stress is considered to be responsible for the development and progression of heart disease. Deficiency of trace elements with antioxidative activities is present in patients with heart disease. Selenium (Se) is an integral part of the enzyme glutathione peroxidase(GPx), one of the central players of the heart's antioxidant system, and it's deficiency is implicated in certain types of heart disease. Our study suggests that myocardial oxidative stress in chronic heart failure may be augmented at least in part by concomitant GPx deficiency, and that the administration of Se could rescue the exhaustion of this selenoprotein, resulting in improved left ventricular function.

    Heart valve disease (HVD) is the most frequent cardiac manifestation in patients with antiphospholipid syndrome (APS), with prevalence of 30 %. The definition is based on the presence of thickening or vegetation of the valves (mainly mitral and aortic) as described by Libman and Sacks for patients with systemic lupus erythematosus (SLE). Transthoracic and/or transoesophageal echocardiography (TTE and TEE, respectively) enable early and accurate diagnosis and help avoid misdiagnosis as rheumatic valve disease. The presence of antiphospholipid antibodies (aPL) in SLE patients is associated with a threefold greater risk of HVD, confirming the crucial importance of these antibodies in the pathogenic process, leading to thrombotic manifestations on valves because of hypercoagulability. Natural history is characterized by worsening of HVD over time with an increased risk for stroke. APS patients undergoing valve-replacement surgery are at high risk of thrombotic and bleeding complications. Thus aPL-associated HVD has affects clinical management of APS patients. PMID:23456852

    Unlike a few decades ago, today most patients with congenital heart disease reach adulthood after intervention or reparative surgery. As complete correction is generally not possible, a patient population with great complexity and a particular challenge to medical management is rising and a regular follow-up is mandatory. The aim of care is the timely recognition of residual or associated problems. Frequency and intensity of follow-up examinations depend on type and complexity of the lesion. The standard repertoire at follow-up consists of a specific history, clinical examination, ECG, Holter-monitoring, exercise tests, and echocardiography. Depending on the indication, cardio-MRI, CT scan, and sophisticated cardiac catheterization may become necessary. Long-term complications like rhythm disturbances, pulmonary hypertension, or heart failure are frequent, despite optimal care. Acute complications like arrhythmias, infective endocarditis, cerebral events, cerebral abscesses, aortic dissection, pulmonary embolism, and bleeding have to be recognized early and treated appropriately. Additional focus has to be placed on counseling and management of noncardiac disease and surgery, pregnancy and delivery, exercise at work and in private life, driving, and insurance issues. Training and certification of physicians as well as the establishment of specialized centers will help to ensure high quality health care for the affected patient population. PMID:23318541

  14. The Apexcardiogram in Ischemic Heart Disease

    The apexcardiogram (acg), when recorded serially in patients with acute myocardial infarction (ami), preinfarction angina (pia) and stable ischemic heart disease (ihd), appeared to reflect the abnormal patterns of contraction of the left ventricle in these conditions. Thus, paradoxical bulging (dyskinesis) of the systolic wave or increased “a” wave amplitude with gradual recovery over several weeks was found in all 60 patients with documented ami and in 18 of 20 patients with pia. Electrocardiogram changes were noted, however, in only eight of the pia patients. Changes in the acg frequently antedated ischemia in the ecg. Paradoxical bulging of the systolic wave of the acg was additionally noted in patients during the pain of angina pectoris but this promptly disappeared after the administration of nitroglycerine. Patients with classic angina often had normal resting ecg's but abnormal resting acg's. In contrast to the relatively transient abnormalities noted above, the acg remained unchanged in most patients with stable ihd during follow-up of three months to two years. Patients undergoing coronary bypass operations, however, showed immediate improvement in the acg in the postoperative period. These results suggest the acg reflects the contractile pattern of the left ventricle, and may be an indirectly recorded ventriculogram. Its enhanced sensitivity and the earlier development of changes in comparison to the ecg make this a valuable tool in the study of patients with heart disease.

    Summary Each year, the American Heart Association (AHA), in conjunction with the Centers for Disease Control and Prevention, the National Institutes of Health, and other government agencies, brings together the most up-to-date statistics on heart disease, stroke, other vascular diseases, and their risk factors and presents them in its Heart Disease and Stroke Statistical Update. The Statistical Update is a valuable resource for researchers, clinicians, healthcare policy makers, media professionals, the lay public, and many others who seek the best national data available on disease morbidity and mortality and the risks, quality of care, medical procedures and operations, and costs associated with the management of these diseases in a single document. Indeed, since 1999, the Statistical Update has been cited more than 8700 times in the literature (including citations of all annual versions). In 2009 alone, the various Statistical Updates were cited ≈1600 times (data from ISI Web of Science). In recent years, the Statistical Update has undergone some major changes with the addition of new chapters and major updates across multiple areas. For this year’s edition, the Statistics Committee, which produces the document for the AHA, updated all of the current chapters with the most recent nationally representative data and inclusion of relevant articles from the literature over the past year and added a new chapter detailing how family history and genetics play a role in cardiovascular disease (CVD) risk. Also, the 2011 Statistical Update is a major source for monitoring both cardiovascular health and disease in the population, with a focus on progress toward achievement of the AHA’s 2020 Impact Goals. Below are a few highlights from this year’s Update. Death Rates From CVD Have Declined, Yet the Burden of Disease Remains High The 2007 overall death rate from CVD (International Classification of Diseases 10, I00–I99) was 251.2 per 100 000. The rates were 294

    Recent studies of vegetarians confirm a lower risk of fatal heart disease amongst such subjects. Lipid levels are lower in vegetarians, even when the diet of comparable meat-eaters is low in fat. This may partly explain the lower mortality, but it is not clear whether the absence of meat or some other aspect of the vegetarian diet is causal in this relationship. PMID:15559026

    Heart diseases are common and significant contributors to worldwide mortality and morbidity. During recent years complement mediated inflammation has been shown to be an important player in a variety of heart diseases. Despite some negative results from clinical trials using complement inhibitors, emerging evidence points to an association between the complement system and heart diseases. Thus, complement seems to be important in coronary heart disease as well as in heart failure, where several studies underscore the prognostic importance of complement activation. Furthermore, patients with atrial fibrillation often share risk factors both with coronary heart disease and heart failure, and there is some evidence implicating complement activation in atrial fibrillation. Moreover, Chagas heart disease, a protozoal infection, is an important cause of heart failure in Latin America, and the complement system is crucial for the protozoa-host interaction. Thus, complement activation appears to be involved in the pathophysiology of a diverse range of cardiac conditions. Determination of the exact role of complement in the various heart diseases will hopefully help to identify patients that might benefit from therapeutic complement intervention. PMID:25037633

    Objective Gallstone disease (GSD) is related to multiple cardiovascular risk factors; the present study was to prospectively examine the association between GSD and ischemic heart disease (IHD). Approach and Results We examined the association of GSD with IHD among 199,292 men and 288,081 women aged 30–79 years in the China Kadoorie Biobank study. Participants with cancer, heart disease, and stroke at baseline were excluded. Cox proportional hazards regression model was used to estimate the association of GSD with IHD. The prevalence of self-reported GSD was 3.7% in men and 7.3% in women at baseline. During 3,431,124 person-years of follow-up between 2004 and 2013 (median, 7.2 years), we documented 10,245 incident IHD cases in men and 14,714 in women. As compared with men without GSD at baseline, the multivariate-adjusted hazard ratio for IHD was 1.11 (95% confidence interval [CI], 1.02–1.22) for men with GSD; the respective hazard ratio was 1.27 (95% CI, 1.20–1.34) in women and 1.23 (95% CI, 1.17–1.28) in the whole cohort. The sex difference in IHD risk associated with GSD was statistically significant (P=0.009 for interaction with sex). In addition, we found the association between GSD and IHD was stronger in non-hypertensive than hypertensive women (P<0.001 for interaction). Conclusions In this large prospective study, the presence of GSD was associated with an increased risk of incident IHD, independent of other risk factors of cardiovascular disease. Our findings suggest novel prevention strategy to mitigate heart disease through improvement of gastrointestinal health. PMID:26272939

    The modern Western diet bears little resemblance to the diet which forged the human genome over many million years. The change in basic food structure is operating to distort biology even before conception and into late years, with the epidemic of obesity and diabetes likely to lead to stroke, heart disease, and now dementia, being flagged as a consequence. In addition, mental ill health is overtaking all other burdens of ill health, and almost certainly has its roots in early disturbance of brain development. Whilst lifestyle will be playing its part, there can be little doubt that the common denominator is the aberrations in food development, predominantly in the last century. It seems it is time to reassess food policy. The principle of food production should be nutrition and human health. The globalisation of a food structure linked to such disorders and their appearance globally in response asks that steps be taken to protect other countries from making the same mistakes.

    With high mortality and readmission rates among patients with heart failure (HF), multiple disease management models have been and continue to be tested, with mixed results. Early postdischarge care improves outcomes for patients. Telemonitoring also can assist in reducing mortality and HF-related hospitalizations. Office-based team care improves patient outcomes, with important components including rapid access to physicians, partnerships with clinical pharmacists, education, monitoring, and support. Pay-for-performance measures developed for HF, primarily use of angiotensin-converting enzyme inhibitors and beta blockers, also improve patient outcomes, but the influence of adherence to other measures has been minimal. Evaluating comorbid conditions, including diabetes and hypertension, and making drug adjustments for patients with HF to include blood pressure control and use of metformin, when possible, can reduce mortality and morbidity.

  1. FISH CONSUMPTION, METHYLMERCURY, AND HUMAN HEART DISEASE.

    Environmental mercury continues to be of concern to public health advocates, both in the U.S. and abroad, and new research continues to be published. A recent analysis of potential health benefits of reduced mercury emissions has opened a new area of public health concern: adverse effects on the cardiovascular system, which could account for the bulk of the potential economic benefits. The authors were careful to include caveats about the uncertainties of such impacts, but they cited only a fraction of the applicable health effects literature. That literature includes studies of the potentially harmful ingredient (methylmercury, MeHg) in fish, as well as of a beneficial ingredient, omega-3 fatty acids or ''fish oils''. The U.S. Food and Drug Administration (FDA) recently certified that some of these fat compounds that are primarily found in fish ''may be beneficial in reducing coronary heart disease''. This paper briefly summarizes and categorizes the extensive literature on both adverse and beneficial links between fish consumption and cardiovascular health, which are typically based on studies of selected groups of individuals (cohorts). Such studies tend to comprise the ''gold standard'' of epidemiology, but cohorts tend to exhibit a great deal of variability, in part because of the limited numbers of individuals involved and in part because of interactions with other dietary and lifestyle considerations. Note that eating fish will involve exposure to both the beneficial effects of fatty acids and the potentially harmful effects of contaminants like Hg or PCBs, all of which depend on the type of fish but tend to be correlated within a population. As a group, the cohort studies show that eating fish tends to reduce mortality, especially due to heart disease, for consumption rates up to about twice weekly, above which the benefits tend to level off. A Finnish cohort study showed increased mortality risks in the highest fish-consuming group ({approx}3 times

    Acute rheumatic fever (ARF) is the result of an autoimmune response to pharyngitis caused by infection with group A Streptococcus. The long-term damage to cardiac valves caused by ARF, which can result from a single severe episode or from multiple recurrent episodes of the illness, is known as rheumatic heart disease (RHD) and is a notable cause of morbidity and mortality in resource-poor settings around the world. Although our understanding of disease pathogenesis has advanced in recent years, this has not led to dramatic improvements in diagnostic approaches, which are still reliant on clinical features using the Jones Criteria, or treatment practices. Indeed, penicillin has been the mainstay of treatment for decades and there is no other treatment that has been proven to alter the likelihood or the severity of RHD after an episode of ARF. Recent advances - including the use of echocardiographic diagnosis in those with ARF and in screening for early detection of RHD, progress in developing group A streptococcal vaccines and an increased focus on the lived experience of those with RHD and the need to improve quality of life - give cause for optimism that progress will be made in coming years against this neglected disease that affects populations around the world, but is a particular issue for those living in poverty.

    Critical congenital heart disease (CCHD) is defined as a ductal-dependent congenital heart defect requiring surgical or percutaneous intervention via cardiac catheterization before 1 year of age. Most cases of CCHD can be diagnosed with prenatal ultrasound or fetal echocardiogram. If not prenatally diagnosed, CCHD can be stable in the newborn nursery due to persistent ductal patency, and the patient may only be diagnosed after ductal closure and development of cardiac symptoms at home. In this case, a 6-day-old female presented to the emergency department (ED) floppy with agonal respirations, poor capillary refill, and absent femoral pulses. On the day of presentation, the patient became increasingly fussy, refused feeding, and began to gasp. The patient was transported to the ED for evaluation, where a bedside echocardiogram revealed interrupted aortic arch (IAA), ventricular septal defect, minimal flow through a thread-like ductus arteriosus, and severely depressed cardiac function. IAA is very rare, with an incidence of three cases per 1 million live births. Patients require neonatal supportive care, continuous prostaglandin E1 infusion, and urgent referral for neonatal surgical repair in the first days to weeks of life. To reduce the volume of undiagnosed CCHD in the immediate newborn period, the U.S. Department of Health and Human Services Secretary's Advisory Committee on Heritable Diseases in Newborns and Children (SACHDNC) recommended that CCHD screening via pulse oximetry be added to the recommended uniform screening panel. A positive screen results in an immediate referral for an echocardiogram. Fetal diagnosis, newborn screening, and/or careful clinical examination may have resulted in detection of IAA in our patient prior to ductal closure. PMID:24877491

    Congenital heart disease (CHD) is a broad term which encompasses a spectrum of pathology, the most common phenotypes include atrial septal defects (ASDs), ventricular septal defects (VSDs), patent ductus arteriosus (PAD) and tetralogy of Fallot (TOF). The impact of CHD is profound and it is estimated to be responsible for over 40% of prenatal deaths. MicroRNAs (miRs) are small, highly conserved, non-coding RNAs which have complex roles in a variety of pathophysiological states. miRs are post-transcriptional negative regulators of gene expression. Individual miRs are known to exert effects in multiple target genes, therefore the altered expression of a single miR could influence an entire gene network resulting in complex pathological states. Recent evidences suggest a role in the dysregulation of miRs in CHD. Mouse knock out models have contributed to our knowledge base revealing specific patterns of miR expression in cardiovascular physiology and pathological states. Specific miRs necessary for embryonic cardiac development have been revealed. Dysregulation of these miRs has been shown to cause structural abnormalities in the heart and vasculature, thus furthering our understanding of the processes which result in CHD. These advances have provided new insight into the signalling pathways responsible for CHD. Furthermore, this new appreciation for miRs in the development of CHD has uncovered their potential for new therapeutic targets where modulated miR activity may reduce the burden of disease. Here, we summarize current knowledge of the cause-effect relationships of miRs in CHD and consider their potential as a therapeutic targets and biomarkers in this clinical setting. PMID:26734643

    Heart disease is one of the leading causes of morbidity and mortality worldwide and it has been well established that it is associated with both mental and physical conditions. This paper describes the prevalence of heart disease with mental disorders and other chronic physical conditions among the Singapore resident population. Data were from the Singapore Mental Health Study which was a representative, cross-sectional epidemiological survey undertaken with 6616 Singapore residents, between December 2009 and December 2010. The Composite International Diagnostic Interview Version 3.0 was used to establish the diagnosis of mental disorders, while a chronic medical conditions checklist was used to gather information on 15 physical conditions, including various forms of heart disease. Health-related quality of life was measured using the Euro-Quality of Life Scale (EQ-5D). The lifetime prevalence of heart disease was 2.8%. Socio-demographic correlates of heart disease included older age, Indian ethnicity, secondary education (vs. tertiary) and being economically inactive. After adjusting for socio-demographic variables and other comorbid physical and mental disorders, the prevalence of major depressive disorder and bipolar disorder were significantly higher among those with heart disease, as were diabetes, arthritis, kidney failure and lung disease. These findings highlight important associations between heart disease and various socio-demographic correlates, mental disorders and physical conditions. Given the high prevalence of mood disorders among heart disease patients, timely and appropriate screening and treatment of mental disorders among this group is essential. PMID:26957336

    In neurological disease and diabetes, the unfolded protein response (UPR) has been investigated for years, while its function in heart disease is less well understood. All three branches of the UPR are involved in ischaemia/reperfusion and can either protect or impair heart function. Recently, UPR has been found to play a role in arrhythmogenesis during human heart failure, and blocking UPR has an antiarrhythmic effect. This review will discuss the rationale for and challenges to targeting UPR in heart disease. PMID:24865516

    In 2003, the National Heart Foundation of Australia published a position statement on psychosocial risk factors and coronary heart disease (CHD). This consensus statement provides an updated review of the literature on psychosocial stressors, including chronic stressors (in particular, work stress), acute individual stressors and acute population stressors, to guide health professionals based on current evidence. It complements a separate updated statement on depression and CHD. Perceived chronic job strain and shift work are associated with a small absolute increased risk of developing CHD, but there is limited evidence regarding their effect on the prognosis of CHD. Evidence regarding a relationship between CHD and job (in)security, job satisfaction, working hours, effort-reward imbalance and job loss is inconclusive. Expert consensus is that workplace programs aimed at weight loss, exercise and other standard cardiovascular risk factors may have positive outcomes for these risk factors, but no evidence is available regarding the effect of such programs on the development of CHD. Social isolation after myocardial infarction (MI) is associated with an adverse prognosis. Expert consensus is that although measures to reduce social isolation are likely to produce positive psychosocial effects, it is unclear whether this would also improve CHD outcomes. Acute emotional stress may trigger MI or takotsubo ("stress") cardiomyopathy, but the absolute increase in transient risk from an individual stressor is low. Psychosocial stressors have an impact on CHD, but clinical significance and prevention require further study. Awareness of the potential for increased cardiovascular risk among populations exposed to natural disasters and other conditions of extreme stress may be useful for emergency services response planning. Wider public access to defibrillators should be available where large populations gather, such as sporting venues and airports, and as part of the response

    The aim was to review the most interesting articles dealing with estimations of an individual's absolute coronary heart disease risk based on the Framingham heart study. Besides the Framingham coronary heart disease risk functions, results of validation studies of these Framingham risk functions are discussed. In general, the Framingham risk functions overestimated an individual's absolute risk in external (non-Framingham) populations with a lower occurrence of coronary heart disease compared with the Framingham population, and underestimated it in populations with a higher occurrence of coronary heart disease. Even if the calibration accuracy of the Framingham risk functions were not satisfying, the Framingham risk functions were able to rank individuals according to risk from low-risk to high-risk groups, with the discrimination ability of 60% and more.

    Thanks to the enormous progress in the field of cardiac surgery and paediatric cardiology since the mid of 20th century, more and more children with congenital heart defects reach the adulthood. This on the other hand encounter physician and patients various problems due to late complications after the heart surgery like congestive heart failure, arrhythmia and sudden death. One of the challenging area is the medical management of heart failure in these patients with complex anatomy and hemodynamics. The lack of evidence of the effectiveness of the anti congestive medications in this population in from of large randomized controlled trials, makes it difficult to establish universally accepted therapy guidelines. In this article we will review the evidence of the beta-blockers in heart failure in patients with congenital heart disease. Also we will discuss the mechanisms of heart failure in this patient's cohort and will review the literature with respect to the use of neurohormonal antagonists in congenital heart disease. There is an urgent need to initiate well-designed clinical trials to prove if the positive results of neurohormonal blockade in acquired heart failure in adults can be translated in patients with congenital heart disease.

    Background: In its Constitution of 1948, WHO defined health as “a state of complete physical, mental, and social well-being, and not merely the absence of disease and infirmity” . In 1994, the Agency for Health Care Policy and Research published clinical practice guidelines recommending providers to routinely evaluate patients’ HRQoL (Health Related Quality of Life) and use their assessment to modify and guide patient care. Objectives: to create a valid, sensitive, disease-specific Persian health status quality of life questionnaire for patients with chronic heart failure in Iran. Materials and Methods: Considering the existing relevant inventories and scientific literature, the authors designed the first draft of questionnaire which was modified and validated, using expert opinions and finalized in a session of expert panel. The questionnaire was processed among 130 patients with heart failure. Construct validity evaluated by principle component factor analysis, and promax method was used for factor rotation. MacNew quality of life questionnaire was selected to assess convergence validity, and the agreements were measured in 60 patients. Discriminant validity was also assessed. Thirty patients were followed for 3 months and responsiveness of questionnaire was measured. Cronbach's alpha, item analysis, and Intra-class correlation coefficients (ICCs) were used to investigate reliability of questionnaire. SPSS 15 for Windows was applied for statistical analysis. Results: Principle component factor analysis revealed 4 main components. Sub-group analysis suggested that IHF-QoL questionnaire demonstrated an acceptable discriminant validity. High conformity between this inventory and MacNew questionnaire revealed an appropriate convergence validity. Cronbach's alpha (α) for the overall questionnaire was equal to 0.922. Intra-class correlation coefficients (ICCs) for all components were significant (from. 708 to. 883; all P values < 0.001). Patients fallow

    The possibility has been raised in recent years that infection might contribute as an inflammatory stimulus to chronic "noninfectious" degenerative diseases. Within the past decade, serious attention has been given to the possibility of bacterial vectors as causal factors of atherosclerosis. To date, the greatest amount of information has related to the intracellular organism Chlamydia pneumoniae. This interest has been stimulated by the frequent finding of bacterial antigens and, occasionally, recoverable organisms, within human atherosclerotic plaque. Indirect evidence for and against the benefit of anti-Chlamydia antibiotic agents comes from epidemiologic studies. Given the potential for confounding in observational studies, prospective, randomized intervention trials are required. These antibiotic trials have generated enthusiastic expectations for proving (or disproving) the infectious-disease hypothesis of atherosclerosis and establishing new therapies. However, these expectations have been tempered by important limitations and uncertainties. Negative outcomes can be explained not only by an incorrect hypothesis but also by inadequate study size or design or by an ineffective antibiotic regimen. In contrast, if studies are positive, the hypothesis still is not entirely proved, because a nonspecific anti-inflammatory effect or an anti-infective action against other organisms might be operative. The clinical trial data to date have not provided adequate support for the clinical use of antibiotics in primary or secondary prevention of coronary heart disease. New and innovative experimental approaches, in addition to traditionally designed antibiotic trials, should be welcome in our attempts to gain adequate insight into the role of infection in atherosclerosis and its therapy.

Methods Data were obtained from DATASUS and death declaration records with codes I20 and I24 for acute ischemic diseases, I25 for chronic ischemic diseases, and I50 for heart failure, and codes in chapter XIII for ill-defined causes, according to geoeconomic regions of Brazil, from 1996 to 2011. Results Mortality rates due to heart failure declined in Brazil and its regions, except for the North and the Northeast. Mortality rates due to acute ischemic heart diseases increased in the North and Northeast regions, especially from 2005 on; they remained stable in the Center-West region; and decreased in the South and in the Southeast. Mortality due to chronic ischemic heart diseases decreased in Brazil and in the Center-West, South and Southeast regions, and had little variation in the North and in the Northeast. The highest mortality rates due to ill-defined causes occurred in the Northeast until 2005. Conclusions Mortality due to heart failure is decreasing in Brazil and in all of its geoeconomic regions. The temporal evolution of mortality caused by ischemic heart diseases was similar to that of heart failure. The decreasing number of deaths due to ill-defined causes may represent the improvement in the quality of information about mortality in Brazil. The evolution of acute ischemic heart diseases ranged according to regions, being possibly confused with the differential evolution of ill-defined causes. PMID:25004417

    Smoking is the leading preventable cause of illness and premature death in Germany, claiming over 110,000 lives a year because it directly increases the risk of dying from heart disease, stroke, emphysema and a variety of cancers. The overwhelming majority of smokers begin tobacco use before they reach adulthood. Among those young people who smoke, the average age is now 13-14. In Germany, about 39% of male and 31% of female adults (age 18-60 years) continue to smoke, despite information about the unequivocally negative health consequences of smoking. The exact mechanisms of smoking-related vascular disease are not yet known. Smoking causes acute hemodynamic alterations such as increase in heart rate, systematic and coronary vascular resistance, myocardial contractility, and myocardial oxygen demand. These short-term effects could lower the ischemic threshold in smokers with coronary artery disease and contribute to the increased risk for acute cardiovascular events. Endothelial damage is thought to be an initiating event in atherosclerosis and early studies have demonstrated that long-term smoking has direct toxic effects with structural changes of human endothelial cells. Recent research has shown the importance of the functional role of the endothelium in regulating vascular tone, platelet-endothelial interactions, leukocyte adhesion and smooth muscle cell proliferation via synthesis and release of a variety of substances such as nitric oxide. There is strong evidence that smoking leads to endothelial dysfunction mainly by increased inactivation of nitric oxide by oxygen-derived free radicals. Smoking also increases oxidative modification of LDL and is associated with lower HDL plasma levels. Smoking induces a systemic inflammatory response with increased leukocyte count and elevation of the C-reactive protein level. Importantly, the prothrombotic effects of smoking have been repeatedly demonstrated to cause alterations in platelet function, imbalance of

    Abstract Stem cell transplantation has emerged as a novel treatment option for ischemic heart disease. Different cell types have been utilized and the recent development of induced pluripotent stem cells has generated tremendous excitement in the regenerative field. Bone marrow-derived multipotent progenitor cell transplantation in preclinical large animal models of postinfarction left ventricular remodeling has demonstrated long-term functional and bioenergetic improvement. These beneficial effects are observed despite no significant engraftment of bone marrow cells in the myocardium and even lower differentiation of these cells into cardiomyocytes. It is thought to be related to the paracrine effect of these stem cells, which secrete factors that lead to long-term gene expression changes in the host myocardium, thereby promoting neovascularization, inhibiting apoptosis, and stimulating resident cardiac progenitor cells. Future studies are warranted to examine the changes in the recipient myocardium after stem cell transplantation and to investigate the signaling pathways involved in these effects. Antioxid.

    Congenital heart disease in children is a type of birth defect. Previous studies have suggested that the transcription factor, TBX20, is involved in the occurrence and development of congenital heart disease in children; however, the specific regulatory mechanisms are yet to be evaluated. Hence, this study aimed to evaluate the relationship between the TBX20 polymorphism and the occurrence and development of congenital heart disease. The TBX20 gene sequence was obtained from the NCBI database and the polymorphic locus candidate was predicted. Thereafter, the specific gene primers were designed for the restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR) of DNA extracted from the blood of 80 patients with congenital heart disease and 80 controls. The results of the PCR were subjected to correlation analysis to identify the differences between the amplicons and to determine the relationship between the TBX20 gene polymorphism and congenital heart disease. One of the single nucleotide polymorphic locus was found to be rs3999950: c.774T>C (Ala265Ala). The TC genotype frequency in the patients was higher than that in the controls, similar to that for the C locus. The odds ratio of the TC genotypes was above 1, indicating that the presence of the TC genotype increases the incidence of congenital heart diseases. Thus, rs3999950 may be associated with congenital heart disease, and TBX20 may predispose children to the defect. PMID:27323105

    Congenital heart defects affect nearly 1% of all newborns and are a significant cause of infant death. Clinical studies have identified a number of congenital heart syndromes associated with mutations in genes that are involved in the complex process of cardiogenesis. The African clawed frog, Xenopus, has been instrumental in studies of vertebrate heart development and provides a valuable tool to investigate the molecular mechanisms underlying human congenital heart diseases. In this review, we discuss the methodologies that make Xenopus an ideal model system to investigate heart development and disease. We also outline congenital heart conditions linked to cardiac genes that have been well-studied in Xenopus and describe some emerging technologies that will further aid in the study of these complex syndromes.

    Congenital heart disease (CHD) is a common structural defect of the heart or major blood vessels. Patients with adult congenital heart disease (ACHD) have medical needs that are distinct from those of pediatric patients with CHD, and the transition into adult health care is important for management of the patient with ACHD. A large proportion of patients with CHD develop diseases and complications associated with the long-term stress of intracardiac shunts. Pulmonary arterial hypertension (PAH) is a significant complication of some CHD lesions. The treatment of these patients remains challenging due to their combined heart and lung disease, and multidisciplinary care is ofen necessitated for a variety of secondary conditions. A number of treatment options are available for the management of PAH associated with CHD, including prostanoids, phosphodiesterase type-5 inhibitors, and endothelin receptor antagonists. This article discusses the diagnosis and management of such ACHD patients with PAH. PMID:22104452

    Exploring biological systems from highly complex datasets is an important task for systems biology. The present study examined co-expression dynamics of mouse heart transcriptome by spectral graph clustering (SGC) to identify a heart transcriptomic network. SGC of microarray data produced 17 classified biological conditions (called condition spectrum, CS) and co-expression patterns by generating bi-clusters. The results showed dynamic co-expression patterns with a modular structure enriched in heart-related CS (CS-1 and -13) containing abundant heart-related microarray data. Consequently, a mouse heart transcriptomic network was constructed by clique analysis from the gene clusters exclusively present in the heart-related CS; 31 cliques were used for constructing the network. The participating genes in the network were closely associated with important cardiac functions (e. g., development, lipid and glycogen metabolisms). Online Mendelian Inheritance in Man (OMIM) database indicates that mutations of the genes in the network induced serious heart diseases. Many of the tested genes in the network showed significantly altered gene expression in an animal model of hypertrophy. The results suggest that the present approach is critical for constructing a heart-related transcriptomic network and for deducing important genes involved in the pathogenesis of various heart diseases.

    The objective of this review is to propose a conceptual model for heart failure (HF) disease management (HFDM) and to define the components of an efficient HFDM plan in reference to this model. Articles that evaluated 1 or more of the following aspects of HFDM were reviewed: (1) outpatient clinic follow-up; (2) self-care interventions to enhance patient skills; and (3) remote evaluation of worsening HF either using structured telephone support (STS) or by monitoring device data (telemonitoring). The success of programs in reducing readmissions and mortality were mixed. Outpatient follow-up programs generally resulted in improved outcomes, including decreased readmissions. Based on 1 meta-analysis, specialty clinics improved outcomes and nonspecialty clinics did not. Results from self-care programs were inconsistent and might have been affected by patient cognitive status and educational level, and intervention intensity. Telemonitoring, despite initially promising meta-analyses demonstrating a decrease in the number and duration of HF-related readmissions and all-cause mortality rates at follow-up, has not been shown in randomized trials to consistently reduce readmissions or mortality. However, evidence from device monitoring trials in particular might have been influenced by technology and design issues that might be rectified in future trials. Results from the literature suggest that the ideal HFDM plan would include outpatient follow-up at an HF specialty clinic and continuous education to improve patient self-care. The end result of this plan would lead to better understanding on the part of the patient and improved patient ability to recognize and respond to signs of decompensation. PMID:24565255

    Cardinal pathologic features of hypertensive heart disease (HHD) include not only hypertrophied cardiomyocytes and foci of scattered microscopic scarring, a footprint of prior necrosis, but also small myocytes ensnared by fibrillar collagen where disuse atrophy with protein degradation would be predicted. Whether atrophic signaling is concordant with the appearance of HHD and involves oxidative and endoplasmic reticulum (ER) stress remains unexplored. Herein, we examine these possibilities focusing on the left ventricle (LV) and cardiomyocytes harvested from hypertensive rats receiving 4 wks aldosterone/salt treatment (ALDOST) alone or together with ZnSO4, a nonvasoactive antioxidant, with the potential to attenuate atrophy and optimize hypertrophy. Compared to untreated age-/sex-/strain-matched controls, ALDOST was accompanied by: a) LV hypertrophy with preserved systolic function; b) concordant cardiomyocyte atrophy (<1000 μm2) found at sites bordering on fibrosis where they were re-expressing β-myosin heavy chain; and c) upregulation of ubiquitin ligases, MuRF1 and atrogin-1, and elevated 8-isoprostane and unfolded protein ER response with mRNA upregulation of stress markers. ZnSO4 cotreatment reduced lipid peroxidation, fibrosis and the number of atrophic myocytes, together with a further increase in cell area and width of atrophied and hypertrophied myocytes, and improved systolic function, but did not attenuate elevated blood pressure. We conclude that atrophic signaling, concordant with hypertrophy, occurs in the presence of a reparative fibrosis and induction of oxidative and ER stress at sites of scarring where myocytes are atrophied. ZnSO4 cotreatment in HHD with ALDOST attenuates the number of atrophic myocytes, optimizes size of atrophied and hypertrophied myocytes, and improves systolic function. PMID:24084216

    Ischemic heart disease (IHD) is the leading cause of death and disability worldwide. An early and accurate diagnosis of IHD is necessary to improve outcomes. According to recent guidelines, the diagnosis of acute myocardial infarction (AMI) is based on increased or decreased value of cardiospecific troponins with one measure exceeding the 99th percentile upper reference limit, associated with symptoms suggestive for myocardial ischemia, indicative electrocardiogram abnormalities, and evidence of recent myocardial functional impairment or intracoronary thrombosis. The recent advent of highly sensitive troponin immunoassays has represented a paradigm shift, wherein the improved analytical sensitivity has increased the negative predictive value, while contextually decreasing the diagnostic specificity of these tests. Although several additional biomarkers have been proposed as surrogate or in combination with troponins, there is little evidence that any of these will substantially improve AMI diagnosis. With regard to therapy, early mechanical (i.e., percutaneous coronary intervention, PCI) or pharmacological reperfusion should be performed early in ST-segment elevation myocardial infarction (STEMI) within 12 h of symptom onset, whereas fibrinolysis may be considered in all other circumstances. Patients undergoing primary PCI should also receive a combination of double antiplatelet therapy (i.e., aspirin and adenosine diphosphate receptor blocker), associated with parenteral anticoagulation, preferably with low-molecular-weight heparin. In analogy with STEMI, a wealth of data shows that primary early invasive strategy (i.e., PCI) and antiplatelet therapy remains the cornerstone of management of patients with non-ST segment elevation acute coronary syndrome. Stem cell-based therapy has also emerged as a potentially therapeutic option, and there are ongoing efforts among several investigators to translate basic research into clinical practice.

    Aim: Ischemic heart disease is a life-threatening condition. Considerable doubts exist over the effects of this disease on patients’ sexual activity and satisfaction. The aim of this study was to evaluate the relationship between ischemic heart disease and sexual satisfaction. Methods: In a retrospective cohort study, the convenience sample of 150 patients exposure with ischemic heart disease and 150 people without exposure it was drawn from Shahid Beheshti hospital, Kashan, Iran. Sampling was performed from March to September 2014. We employed the Larson’s Sexual Satisfaction Questionnaire for gathering the data. Data were analyzed using descriptive statistics and Chi-square, t-test and linear regression analysis. Results: The means of sexual satisfaction in patients exposure with ischemic heart disease and among the subjects without exposure it were 101.47±13.42 and 100.91±16.52, respectively. There was no significant difference between the two groups regarding sexual satisfaction. However, sexual satisfaction was significantly correlated with gender and the use of cardiac medications (P value < 0.05). Conclusion: The level of sexual satisfaction in patients with exposure ischemic heart disease is similar to the people without exposure it. Moreover, the men and the patients who do not receive cardiac medications have higher levels of sexual satisfaction. Nurses who are providing care to patients with ischemic heart disease need to pay closer attention to patient education about sexual issues. PMID:26234982

    Rheumatic heart disease, already a major burden in low- and middle-income countries, is becoming an emerging problem in high-income countries. Although acute rheumatic fever and rheumatic heart disease have almost been eradicated in areas with established economies, the emergence of this problem may be attributable to the migration from low-income to high-income settings. Between 2010 and 2012, we diagnosed a cluster of rheumatic heart disease cases in children from the Middle Tennessee area. The goal of this report is to increase awareness among clinicians as the incidence and prevalence of acute rheumatic fever remain relatively significant in large US metropolitan areas. Although acute rheumatic fever is seasonal, a high suspicion index may lead to the early diagnosis and prevention of its cardiac complications. Furthermore, screening procedures may be recommended for populations at risk for rheumatic heart disease in endemic areas, and active surveillance with echocardiography-based screening might become very important.

    Heart failure is a major cause of mortality worldwide with a steady increase in prevalence. There is currently no available cure beyond orthotopic heart transplantation, which for a number of reasons is an option only for a small fraction of all patients. Considerable hope has therefore been placed on the possibility of treating a failing heart by replacing lost cardiomyocytes, either through transplantation of various types of stem cells or by boosting endogenous regenerative mechanisms in the heart. Here, we review the current status of stem and progenitor cell-based therapies for heart disease. We discuss the pros and cons of different stem and progenitor cell types that can be considered for transplantation and describe recent advances in the understanding of how cardiomyocytes normally differentiate and how these cells can be generated from more immature cells ex vivo. Finally, we consider the possibility of activation of endogenous stem and progenitor cells to treat heart failure. PMID:23331408

    The prevalence of ischaemic heart disease was determined by an administered questionnaire and electrocardiography in 7735 men aged 40-59 years drawn at random from general practices in 24 British towns. Overall, one quarter of these men had some evidence of ischaemic heart disease on questionnaire or electrocardiogram or both. On questionnaire, 14% of men had possible myocardial infarction or angina, with considerable overlap of the two syndromes. The prevalence of possible myocardial infarction combined with angina and of definite angina only showed a fourfold increase over the age range studied. Electrocardiographic evidence of ischaemic heart disease (definite or possible) was present in 15% of men, there being myocardial infarction in 4.2% and myocardial ischaemia in 10.3%. Electrocardiographic evidence of myocardial infarction increased fourfold over the age range studied. There was considerable overlap of questionnaire and electrocardiographic evidence of ischaemic heart disease. Nevertheless, more than half of those with possible myocardial infarction combined with angina had no resting electrocardiographic evidence of ischaemic heart disease, and half of those with definite myocardial infarction on electrocardiogram had no history of chest pain at any time. This national population based study strongly suggests that the prevalence of ischaemic heart disease in middle aged British men is greater than has been indicated by previous studies based on occupational groups.

    OBJECTIVE: To review the relationship between congenital heart defects and chromosomal abnormalities detected by the karyotype. DATA SOURCES: Scientific articles were searched in MEDLINE database, using the descriptors "karyotype" OR "chromosomal" OR "chromosome" AND "heart defects, congenital". The research was limited to articles published in English from 1980 on. DATA SYNTHESIS: Congenital heart disease is characterized by an etiologically heterogeneous and not well understood group of lesions. Several researchers have evaluated the presence of chromosomal abnormalities detected by the karyotype in patients with congenital heart disease. However, most of the articles were retrospective studies developed in Europe and only some of the studied patients had a karyotype exam. In this review, only one study was conducted in Latin America, in Brazil. It is known that chromosomal abnormalities are frequent, being present in about one in every ten patients with congenital heart disease. Among the karyotype alterations in these patients, the most important is the trisomy 21 (Down syndrome). These patients often have associated extra-cardiac malformations, with a higher risk of morbidity and mortality, which makes heart surgery even more risky. CONCLUSIONS: Despite all the progress made in recent decades in the field of cytogenetic, the karyotype remains an essential tool in order to evaluate patients with congenital heart disease. The detailed dysmorphological physical examination is of great importance to indicate the need of a karyotype. PMID:25119760

  20. Cereal grains and coronary heart disease.

    Truswell, A S

    2002-01-01

    Cereal grains and their products provide around 30% of total energy intake in British adults, (much more than any of the other major food groups). Coronary heart disease (CHD) is the largest single cause of death in Britain and many other Western countries. This review examines the question whether there is a relation between cereal consumption and CHD. Several of the nutrients in cereals have known potential for reducing risk factors for CHD: the linoleic acid, fibre, vitamin E, selenium and folate. Cereals also contain phytoestrogens of the lignan family and several phenolic acids with antioxidant properties. Processing generally reduces the content of these nutrients and bioprotective substances. Although cereals at the farm gate are very low in salt, processed cereal foods, eg bread and some breakfast cereals, are high-salt foods and thus could contribute to raising blood pressure. Human experiments have clearly shown that oat fibre tends to lower plasma total and LDL cholesterol but wheat fibre does not. Rice bran and barley may also lower cholesterol but most people do not eat enough barley to have an effect. Cereal foods with low glycaemic index such as pasta and oats are beneficial for people with diabetes and might lower plasma lipids. Between 1996 and 2001 an accumulation of five very large cohort studies in the USA, Finland and Norway have all reported that subjects consuming relatively large amounts of whole grain cereals have significantly lower rates of CHD. This confirms an earlier report from a small British cohort. The protective effect does not seem to be due to cholesterol-lowering. While cohort studies have shown this consistent protective effect of whole grain cereals, there has been (only one) randomised controlled secondary prevention trial of advice to eat more cereal fibre. In this there was no reduction of the rate of reinfarction. The trial had some weaknesses, eg there were eight different diets, compliance was not checked objectively

    Worldwide, the numbers of women who have a pre-existing cardiovascular disease or develop cardiac problems during pregnancy are increasing and, due to the lack of evidenced-based data, this provides challenges for the treating physician. Cardiovascular disease in pregnancy is a complex topic as women can present either pre- or post-partum, due to a pre-existing heart disease such as operated on or unoperated on congenital heart disease, valvular heart disease, chronic hypertension, or familial dilated cardiomyopathy. Women often present with symptoms and signs of acute heart failure. On the other hand, there are diseases which are directly related to pregnancy, such as hypertensive disorders of pregnancy and peripartum cardiomyopathy, or where pregnancy increases risk of a disease as, for example, the risk of myocardial infarction. These diseases can have long-term implications to the life of the affected women and their families. There is, in particular, a paucity of data from developing countries of this unique disease pattern and its presentations. This review summarizes the current knowledge of the incidence and prevalence of pregnancy-related cardiovascular disease in women presenting pre- or post-partum. PMID:24459193

    Fibrocytes contribute significantly to fibrosis in many cardiac diseases. However, it is not clear whether fibrocytes are associated with the fibrosis in coronary heart disease (CHD). The aim of this study was to determine whether fibrocytes are involved in cardiac fibrosis in CHD. We identified the presence of fibrocytes in CHD heart by immunofluorescence and confocal microscopy, examined the collagen volume fraction by Masson's Trichrome staining, and evaluated the correlation between fibrocytes and cardiac fibrosis. In conjunction, we examined the location of CXCL12, a homing factor and specific ligand for CXCR4, by immunohistochemistry. Fibrocytes were identified in 26 out of 27 CHD hearts and in 10 out of 11 normal hearts. Combinations, including CD34/αSMA, CD34/procollagen-I, CD45/αSMA, CXCR4/procollagen-I and CXCR4/αSMA, stained significantly more fibrocytes in CHD hearts as compared with those in normal hearts (p<0.05). There were positive correlations between the collagen volume fraction and the amount of fibrocytes (r=0.558; p=0.003<0.01) and between the number of CXCR4(+) fibrocytes and the CXCL12(+) cells (r=0.741; p=0.000<0.01) in CHD hearts. Based upon these findings, we conclude that fibrocytes, likely recruited through the CXCR4/CXCL12 axis, may contribute to the increase in the fibroblast population in CHD heart. PMID:23177618

    Mere diagnosis of a valvular heart lesion without circulatory incapacity is inconsequential in considering the prognosis for a pregnant woman. There are grave dangers of heart failure during pregnancy, labor or the postpartum period in women who have had congestive failure prior to pregnancy or during a previous pregnancy and delivery. Decisions as to whether or not to recommend avoidance of pregnancy or therapeutic abortion should depend not alone upon the prospect of death during gestation or at the time of delivery, but also upon the possibility of increased impairment of heart function and physical incapacity of the mother in the postpartum period. Because of the extensive surgical procedure there are few indications for interrupting pregnancy after the third lunar month; and because the major circulatory loads do not increase after the eighth month, rarely should labor be prematurely induced after that time. The exertion of labor, although generally inconsequential, in some cases may produce sustained oxygen debt. In cases in which labor in a previous pregnancy has been accompanied by heart failure, cesarean section should be considered as a means of lessening the possibility of serious failure or death, although this is not a frequent consideration. In the resemblance of circulatory changes that occur, during delivery and immediately postpartum, to those changes produced by the closure of an arteriovenous shunt or patent ductus arteriosus, lies a suggestion as to some of the causative factors in heart failure during or soon after delivery. Probably of great importance is the decrease in blood volume and hemoconcentration at delivery followed by the return of water to the circulatory system, with consequent transient increase in blood volume, in the postpartum period. Additionally, the rise of venous pressure after use of oxytocic drugs suggests that rapid infusion of blood from an engorged uterus may cause an abrupt and perhaps poorly tolerated hypervolemia

    Due to impressive improvements in surgical repair options, even patients with complex congenital heart disease (CHD) may survive into adulthood and have a high risk of end-stage heart failure. Thus, the number of patients with CHD needing heart transplantation (HTx) has been increasing in the last decades. This paper summarizes the changing etiology of causes of death in heart failure in CHD. The main reasons, contraindications, and risks of heart transplantation in CHD are discussed and underlined with three case vignettes. Compared to HTx in acquired heart disease, HTx in CHD has an increased risk of perioperative death and rejection. However, outcome of HTx for complex CHD has improved over the past 20 years. Additionally, mechanical support options might decrease the waiting list mortality in the future. The number of patients needing heart-lung transplantation (especially for Eisenmenger's syndrome) has decreased in the last years. Lung transplantation with intracardiac repair of a cardiac defect is another possibility especially for patients with interatrial shunts. Overall, HTx will remain an important treatment option for CHD in the near future. PMID:23577237

    Patient: Male, 76 Final Diagnosis: Rheumatic valvular heart disease Symptoms: Breathlessness and leg edema Medication: — Clinical Procedure: Medical treatment for heart failure Specialty: Cardiology Objective: Rare disease Background: Complete calcification of the left atrium (LA) is called “coconut atrium”, which decreases the compliance of LA, leading to the elevation of LA pressure that is transmitted to the right-side of the heart. The pathogenesis of LA calcification in patients with rheumatic heart disease is unknown; however, possible mechanisms include chronic strain force in the atrial wall and inflammation. We report here a patient with long-standing rheumatic valvular heart disease with coconut atrium. Case Report: A 76-year-old man presented with breathlessness and leg edema due to right-sided heart failure. He was diagnosed with rheumatic fever at 8 years of age. Mitral commissurotomy and the mitral and aortic valve replacement were previously performed to treat mitral and aortic valvular stenosis. The profile view of the chest X-ray indicated a diffuse calcified outline of the LA wall. A transthoracic echocardiogram revealed pulmonary hyper-tension and dilatation of both atria. Moreover, computed tomography showed nearly circumferential calcification of the LA wall. Despite intense medical treatment, he succumbed to heart failure. An autopsy demonstrated that the LA was markedly dilated, its wall was calcified, and its appearance was similar to the surface of an atherosclerotic aorta. Microscopic examination revealed intensive calcification in the endocardium. Minimal accumulation of inflammatory cells was noted. Although slight fibrosis was observed, the cardiac musculature was preserved. Conclusions: To the best of our knowledge, this is the first report that identifies the histological changes of LA calcification associated with long-standing rheumatic valvular heart disease.

    Pimobendan is a drug with both inotropic and vasodilatory properties and is widely used for the treatment of heart failure in dogs. The best evidence regarding its efficacy is derived from several clinical studies of dogs with the two most common conditions that result in heart failure: dilated cardiomyopathy (DCM) and degenerative mitral valve disease (DMVD). The main studies addressing the effectiveness of pimobendan in dogs with DCM and DVMD are discussed in this article. PMID:20610012

    There is a clinically staggering burden of disease stemming from cerebrovascular events, of which a majority are ischemic in nature and many are precipitated by atrial fibrillation (AF). AF can occur in isolation or in association with myocardial or structural heart disease. In the latter case, and when considering health at an international level, congenital and acquired valve-related diseases are frequent contributors to the current pandemic of AF and its clinical impact. Guidelines crafted by the American Heart Association, American College of Cardiology, European Society of Cardiology and Heart Rhythm Society underscore the use of vitamin K antagonists (VKAs) among patients with valvular heart disease, particularly in the presence of concomitant AF, to reduce the risk of ischemic stroke of cardioembolic origin; however, the non-VKAs, also referred to as direct, target-specific or new oral anticoagulants (NOACs), have not been actively studied in this particular population. In fact, each of the new agents is approved in patients with AF not caused by a valve problem. The aim of our review is to carefully examine the available evidence from pivotal phase 3 clinical trials of NOACs and determine how they might perform in patients with AF and concomitant valvular heart disease.

    With the advent of large-scale imaging studies and big health data, and the corresponding growth in analytics, machine learning and computational image analysis methods, there are now exciting opportunities for deepening our understanding of the mechanisms and characteristics of heart disease. Two emerging fields are computational analysis of cardiac remodelling (shape and motion changes due to disease) and computational analysis of physiology and mechanics to estimate biophysical properties from non-invasive imaging. Many large cohort studies now underway around the world have been specifically designed based on non-invasive imaging technologies in order to gain new information about the development of heart disease from asymptomatic to clinical manifestations. These give an unprecedented breadth to the quantification of population variation and disease development. Also, for the individual patient, it is now possible to determine biophysical properties of myocardial tissue in health and disease by interpreting detailed imaging data using computational modelling. For these population and patient-specific computational modelling methods to develop further, we need open benchmarks for algorithm comparison and validation, open sharing of data and algorithms, and demonstration of clinical efficacy in patient management and care. The combination of population and patient-specific modelling will give new insights into the mechanisms of cardiac disease, in particular the development of heart failure, congenital heart disease, myocardial infarction, contractile dysfunction and diastolic dysfunction.

    Non-valvular heart disease is an important cause of cardiac disease in pregnancy and presents a unique challenge to the anesthesiologist during labor and delivery. A keen understanding of the underlying pathophysiology, in addition to the altered physiology of pregnancy, is the key to managing such patients. Disease-specific goals of management may help preserve the hemodynamic and ventilatory parameters within an acceptable limit and a successful conduct of labor and postpartum period. PMID:20442539

    The American Heart Association estimates that 81% of people who die of coronary heart disease are 65 years old or older. The leading risk health behaviors include physical inactivity, poor diet, smoking, and binge drinking. Using the 2011-2012 California Health Interview Survey (CHIS), this study looked at how self-management, which includes a plan developed by a medical professional and the confidence to manage one's disease, may decrease negative risk behaviors in older adults. The presence of a plan and increased self-efficacy decreased engagement in negative dietary behaviors and low physical activity. Implications for strategies that address heart disease and self-management are discussed. PMID:26566582

    Pulmonary hypertension associated with left heart disease is the most common form of pulmonary hypertension. Although its pathophysiology remains incompletely understood, it is now well recognized that the presence of pulmonary hypertension is associated with a worse prognosis. Right ventricular failure has independent and additive prognostic value over pulmonary hypertension for adverse outcomes in left heart disease. Recently, several new terminologies have been introduced to better define and characterize the nature and severity of pulmonary hypertension. Several new treatment options including the use of pulmonary arterial hypertension specific therapies are being considered, but there is lack of evidence. Here, we review the recent advances in this field and summarize the diagnostic and therapeutic modalities of use in the management of pulmonary hypertension associated with left heart disease.

    The successes in managing infants and children with congenital heart disease have led to an emerging population of adult patients. As we enter this new century, the majority of patients with congenital heart disease will be adults, not children. It is important to maintain our commitment for continuing care to the emerging adult population. Psycho-social issues, including employment and pregnancy counseling, are required as well as the ongoing need for medical and occasionally surgical intervention. The health care system needs to develop supra-regional tertiary referral centers for care of these patients and provide information sharing and support for community-based physicians interested in the welfare of the adult with congenital heart disease.

  19. Plasma homocysteine levels in patients with coronary heart disease.

    Hyperhomocysteinemia is being identified as a risk factor for coronary heart disease but its role among Asian Indians has not been studied. This has practical importance because (1) the data generated in the West may not represent Indian population, and (2) the condition is remediable. To assess the magnitude of this problem, we studied 56 patients with coronary heart disease, and 53 control subjects. Details of diet, smoking, medication, hypertension and diabetes were recorded; lipids and sugar levels were estimated in all. Patients with renal and liver diseases were excluded. Serum homocysteine was estimated using liquid chromatography. Both the groups were comparable by age and sex. Higher, but statistically insignificant homocysteine levels were seen in patients with coronary heart disease: 10.98 +/- 9.04 nmol/ml vs 9.41 +/- 3.60 nmol/ml in control subjects. Among males, higher, but statistically insignificant levels were seen in coronary heart disease patients: 11.96 +/- 9.41 nmol/ml vs 9.87 +/- 3.50 nmol/ ml in control subjects; among females, the levels were lower though not significant: 5.10 +/- 1.64 nmol/ml vs 6.39 +/- 2.99 nmol/ml. Sub-group analysis with age 40 as dividing point did not show significant difference. Six (10.7%) patients with coronary heart disease and three (5.7%) control subjects had homocysteine levels above 95th percentile of control subjects (p = NS). Twenty-three (41.1%) coronary heart disease patients and 19 (35.9%) control subjects had levels above 10 nmol/ml (p = NS). We conclude that homocysteine is not a major risk factor for coronary heart disease in the study population. The lack of statistical significance could be due to inadequate sample size although some past studies reporting statistically significant association between coronary heart disease and homocysteine involved similar or smaller number of subjects. Larger studies are warranted to see if ethnic differences also have any role. PMID:9753851

    Due to advances in cardiac surgery, survival of patients with congenital heart disease has increased considerably during the past decades. Many of these patients require repeated cardiovascular magnetic resonance imaging to assess cardiac anatomy and function. In the past decade, technological advances have enabled faster and more robust cardiovascular magnetic resonance with improved image quality and spatial as well as temporal resolution. This review aims to provide an overview of advances in cardiovascular magnetic resonance hardware and acquisition techniques relevant to both pediatric and adult patients with congenital heart disease and discusses the techniques used to assess function, anatomy, flow and tissue characterization.

    Enhanced survival following acute myocardial infarction and the declining prevalence of hypertension and valvular heart disease as contributors to incident heart failure (HF) have fueled the emergence of coronary artery disease (CAD) as the primary risk factor for HF development. Despite the acknowledged role of CAD in the development of HF, the role of coronary revascularization in reducing HF-associated morbidity and mortality remains controversial. The authors review key features of the epidemiology and pathophysiology of CAD in patients with HF as well as the emerging data from recent clinical trials that inform the modern approach to management.

    The FINRISK risk calculator predicts 10-year risk for coronary heart disease, stroke incidence, and their combination. The model is based on 10-year cohort follow-up from 3 different cohorts in 1982, 1987, and 1992 from a random population sample in 3 areas in Finland. Coronary heart disease, stroke, and their combination are predicted by smoking, systolic blood pressure, total cholesterol, high-density lipoprotein cholesterol, diabetes, and family history. The Internet-based calculator is commonly used in Finland in health services to assess the need for hypertension and hypercholesterolemia treatment and is used also in patients' counseling.

    Congenital heart diseases are the most common congenital malformations and account for about eight cases per 1000 births and are often associated with pulmonary arterial hypertension. Increased shear stress and the excess flow through the pulmonary vascular bed due to a systemic-to-pulmonary shunt lead to the development of pulmonary vascular disease and an increase in pulmonary vascular resistance. Without surgical repair approximately 30% of patients develop pulmonary vascular disease. Eisenmenger syndrome represents the extreme end of pulmonary arterial hypertension with congenital heart disease. We summarized the current therapeutic options for pulmonary arterial hypertension; conventional treatments including calcium channel blockers, anticoagulation, digitalis, diuretics, and new treatment: prostacyclin, bosentan, sildenafil, ambrisentan. Preliminary data of new therapies are encouraging with disease significantly improved natural history, but there is need for more evidence-based data. PMID:18333354

    Hypertension is associated with atherosclerosis and cardiac and vascular structural and functional changes. Myocardial ischemia may arise in hypertension independent of coronary artery disease through an interaction between several pathophysiological mechanisms, including left ventricular hypertrophy, increased arterial stiffness and reduced coronary flow reserve associated with microvascular disease and endothelial dysfunction. The present case report demonstrates how contrast stress echocardiography can be used to diagnose myocardial ischemia in a hypertensive patient with angina pectoris but without significant obstructive coronary artery disease. The myocardial ischemia was due to severe resistant hypertension complicated with concentric left ventricular hypertrophy and increased arterial stiffness. PMID:22093163

    Sudden cardiac death (SCD) in young athletes is relatively uncommon but tragic when it occurs. Many of these deaths can be prevented by pre-exercise screening to identify cardiac abnormalities and those at high risk. Although recent research has provided much needed information on SCD in athletes, there remain significant gaps in the knowledge needed to determine an optimal screening protocol. This review examines the incidence and demographics of SCD in athletes and the difficulties in determining whether changes in an athlete's heart are due to training or represent a potentially malignant congenital abnormality. Current guidelines for screening and the intense debate over the use of the 12-lead electrocardiogram are discussed. Lastly, the importance of a response plan to an apparent SCD event that includes on-site/on-field automated external defibrillators will be discussed. A case study that illustrates the challenges in screening is presented. PMID:22687598

    Purpose of review Despite maximum medical and mechanical support therapy, heart failure remains a relentlessly progressive disorder with substantial morbidity and mortality. Autophagy, an evolutionarily conserved process of cellular cannibalization, has been implicated in virtually all forms of cardiovascular disease. Indeed, its role is context dependent, antagonizing or promoting disease depending on the circumstance. Here, we review current understanding of the role of autophagy in the pathogenesis of heart failure and explore this pathway as a target of therapeutic intervention. Recent findings In preclinical models of heart disease, cardiomyocyte autophagic flux is activated; indeed, its role in disease pathogenesis is the subject of intense investigation to define mechanism. Similarly, in failing human heart of a variety of etiologies, cardiomyocyte autophagic activity is upregulated, and therapy, such as with mechanical support systems, elicits declines in autophagy activity. However, when suppression of autophagy is complete, rapid and catastrophic cell death occurs, consistent with a model in which basal autophagic flux is required for proteostasis. Thus, a narrow zone of ‘optimal’ autophagy seems to exist. The challenge moving forward is to tune the stress-triggered autophagic response within that ‘sweet spot’ range for therapeutic benefit. Summary Whereas we have known for some years of the participation of lysosomal mechanisms in heart disease, it is only recently that upstream mechanisms (autophagy) are being explored. The challenge for the future is to dissect the underlying circuitry and titrate the response into an optimal, proteostasis-promoting range in hopes of mitigating the ever-expanding epidemic of heart failure.
