    We investigated cardiovascular disease (CVD) risk factors in 1501 Greeks (613 men and 888 women, aged 40-65 years) referred to outpatients with metabolic syndrome (MetS) and without diabetes mellitus or CVD. The 10-year risk of fatal CVD events was calculated using European Society of Cardiology Systematic Coronary Risk Estimation (ESC SCORE), Hellenic-SCORE, and Framingham equations. Raised blood pressure (BP) and hypertriglyceridemia were more common in men (89.6% vs 84.2% and 86.8% vs 74.2%, respectively; P < .001). Low high-density lipoprotein cholesterol (HDL-C) and abdominal obesity were more common in women (58.2% vs 66.2% and 85.8% vs 97.1%, respectively; P < .001). The 10-year risk of fatal CVD events using HellenicSCORE was higher in men (6.3% +/- 4.3% vs 2.7% +/- 2.1%; P < .001). European Society of Cardiology Systematic Coronary Risk Estimation and Framingham yielded similar results. The risk equations gave similar assessments in a European Mediterranean population except for HellenicSCORE that calculated more MetS women requiring risk modification. This might justify local risk engine evaluation in event-based studies. (Clinical-Trials.gov ID: NCT00416741).

    Schizophrenia is a devastating mental disorder, associated with mortality rates up to three times higher than those in the general population. This post-mortem study sought to investigate the causes of death in a consecutive series of schizophrenia cases, with a specific focus on cardiovascular disease and sudden death. A 10-year review of autopsies in schizophrenia related-cases performed at the Department of Forensic Medicine in Sydney, Australia was undertaken. Premorbid clinical and demographic information was recorded, as well as the key pathological findings and final cause of death. From 2003 to 2012, there were 19,478 postmortem examinations performed of which 683 (3.5%) were deaths in people with a history of schizophrenia. In these cases, the mean age at death was 51years (range 18-93years), with 43% in the 41-60year age group. Males comprised 67% of cases. Overall, 62% of cases had a BMI≥25kg/m(2), indicating overweight or obese individuals. The three primary causes of death were "cardiovascular" (23%), "suicide" (20%), and "drug toxicity" (17%). In 11% of cases (n=72), no definitive cause of death was found, the so-called "unexplained" cases. In conclusion, patients with schizophrenia have premature mortality. The major contributing factors include cardiovascular diseases, suicide and drug toxicity. The "unexplained" and frequently sudden deaths may suggest underlying cardiac arrhythmias as a cause of death in a subgroup of schizophrenia patients. PMID:24028743

    Estimation of absolute risk of cardiovascular disease (CVD), preferably with population-specific risk charts, has become a cornerstone of CVD primary prevention. Regular recalibration of risk charts may be necessary due to decreasing CVD rates and CVD risk factor levels. The SCORE risk charts for fatal CVD risk assessment were first calibrated for Germany with 1998 risk factor level data and 1999 mortality statistics. We present an update of these risk charts based on the SCORE methodology including estimates of relative risks from SCORE, risk factor levels from the German Health Interview and Examination Survey for Adults 2008–11 (DEGS1) and official mortality statistics from 2012. Competing risks methods were applied and estimates were independently validated. Updated risk charts were calculated based on cholesterol, smoking, systolic blood pressure risk factor levels, sex and 5-year age-groups. The absolute 10-year risk estimates of fatal CVD were lower according to the updated risk charts compared to the first calibration for Germany. In a nationwide sample of 3062 adults aged 40–65 years free of major CVD from DEGS1, the mean 10-year risk of fatal CVD estimated by the updated charts was lower by 29% and the estimated proportion of high risk people (10-year risk > = 5%) by 50% compared to the older risk charts. This recalibration shows a need for regular updates of risk charts according to changes in mortality and risk factor levels in order to sustain the identification of people with a high CVD risk.

    Left ventricular (LV) mass and geometry are associated with risk of cardiovascular disease (CVD). We sought to determine whether LV mass and geometry contribute to risk prediction for CVD in adults aged ≥65 years of the Cardiovascular Health Study. We indexed LV mass to body size, denoted as LV mass index (echo-LVMI), and we defined LV geometry as normal, concentric remodeling, and eccentric or concentric LV hypertrophy. We added echo-LVMI and LV geometry to separate 10-year risk prediction models containing traditional risk factors and determined the net reclassification improvement (NRI) for incident coronary heart disease (CHD), CVD (CHD, heart failure [HF], and stroke), and HF alone. Over 10 years of follow-up in 2,577 participants (64% women, 15% black, mean age 72 years) for CHD and CVD, the adjusted hazards ratios for a 1-SD higher echo-LVMI were 1.25 (95% CI 1.14 to 1.37), 1.24 (1.15 to 1.33), and 1.51 (1.40 to 1.62), respectively. Addition of echo-LVMI to the standard model for CHD resulted in an event NRI of -0.011 (95% CI -0.037 to 0.028) and nonevent NRI of 0.034 (95% CI 0.008 to 0.076). Addition of echo-LVMI and LV geometry to the standard model for CVD resulted in an event NRI of 0.013 (95% CI -0.0335 to 0.0311) and a nonevent NRI of 0.043 (95% CI 0.011 to 0.09). The nonevent NRI was also significant with addition of echo-LVMI for HF risk prediction (0.10, 95% CI 0.057 to 0.16). In conclusion, in adults aged ≥65 years, echo-LVMI improved risk prediction for CHD, CVD, and HF, driven primarily by improved reclassification of nonevents.

    Background Surveys measuring effectiveness of public awareness campaigns in reducing cardiovascular disease (CVD) incidence have yielded equivocal findings. The aim of this study was to describe cardiovascular risk factors (CVRFs) changes over the years in an untreated population-based study. Methods Between 2007 and 2012, we conducted a screening campaign for CVRFs in men aged 40 to 65 yrs and women aged 50 to 70 yrs in the western suburbs of Paris. Data were complete for 20,324 participants of which 14,709 were untreated. Results The prevalence trend over six years was statistically significant for hypertension in men from 25.9% in 2007 to 21.1% in 2012 (p=0.002) and from 23% in 2007 to 12.7% in 2012 in women (p<0.0001). The prevalence trend of tobacco smoking decreased from 38.6% to 27.7% in men (p=0.0001) and from 22.6% to 16.8% in women (p=0.113). The Framingham 10-year risk for CVD decreased from 13.3 ± 8.2 % in 2007 to 11.7 ± 9.0 % in 2012 in men and from 8.0 ± 4.1 % to 5.9 ± 3.4 % in women. The 10-year risk of fatal CVD based on the European Systematic COronary Risk Evaluation (SCORE) decreased in men and in women (p <0.0001). Conclusions Over a 6-year period, several CVRFs have decreased in our screening campaign, leading to decrease in the 10-year risk for CVD and the 10-year risk of fatal CVD. Cardiologists should recognize the importance of community prevention programs and communication policies, particularly tobacco control and healthier diets to decrease the CVRFs in the general population.

    Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality worldwide, and educational level seems to be an important determinant of the disease occurrence. The aim of this work was to investigate the association between education status and 10-year incidence of CVD, controlling for various socio-demographic lifestyle and clinical factors. From May 2001 to December 2002, 1514 men and 1528 women (>18 years) without any clinical evidence of CVD or any other chronic disease, at baseline, living in greater Athens area, Greece, were enrolled. In 2011-2012, the 10-year follow-up was performed in 2583 participants (15% of the participants were lost to follow-up). Incidence of fatal or non-fatal CVD was defined according to WHO-ICD-10 criteria. Education status was measured in years of schooling. The 10-year incidence of CVD was 15.7% [95% confidence intervals (CI) 14.1%-17.4%], 19.7% in men and 11.7% in women (Pgender < 0.001). Age-and gender-adjusted analyses revealed that those with low education (<9 years of schooling) were 1.52 times more likely (95% CI 1.03-2.23%) to have CVD compared with those with high education (>12 years of schooling). People in the low education group had higher prevalence of hypertension, diabetes and dyslipidaemias, were more likely to be smokers and sedentary, had less healthy dietary habits, as compared with those in the high education group. When controlling for participants' medical history, smoking, dietary and lifestyle habits, low education was no longer significantly associated with CVD, illustrating the mediating effect of clinical and behavioural factors in the link between education and disease. It was of interest that low education status interacted with alcohol drinking, enhancing the adverse effect of low education on CVD risk (relative risk 1.44, 95% CI 0.94%-2.20%), after various adjustments made. In this study, it was concluded that low educational level was associated with increased CVD risk. This was

    Purpose. To examine the association of the Family Nutrition and Physical Activity (FNPA) screening tool, a behaviorally based screening tool designed to assess the obesogenic family environment and behaviors, with cardiovascular disease (CVD) risk factors in 10-year old children. Methods. One hundred nineteen children were assessed for body mass index (BMI), percent body fat (%BF), waist circumference (WC), total cholesterol, HDL-cholesterol, and resting blood pressure. A continuous CVD risk score was created using total cholesterol to HDL-cholesterol ratio (TC:HDL), mean arterial pressure (MAP), and WC. The FNPA survey was completed by parents. The associations between the FNPA score and individual CVD risk factors and the continuous CVD risk score were examined using correlation analyses. Results. Approximately 35% of the sample were overweight (19%) or obese (16%). The mean FNPA score was 24.6 +/- 2.5 (range 18 to 29). Significant correlations were found between the FNPA score and WC (r = -.35, p<.01), BMI percentile (r = -.38, p<.01), %BF (r = -.43, p<.01), and the continuous CVD risk score (r = -.22, p = .02). No significant association was found between the FNPA score and TC:HDL (r=0.10, p=0.88) or MAP (r=-0.12, p=0.20). Conclusion. Children from a high-risk, obesogenic family environment as indicated with a lower FNPA score have a higher CVD risk factor profile than children from a low-risk family environment.

    Background The FDA currently recommends at least 4 hours of recipient monitoring to detect early infusion reactions; recent catastrophic reactions to “first in man” biological agents have emphasized the importance of this rule for initial studies of new products. The value of such monitoring for better established agents is less obvious. Methods We therefore reviewed infusion-related adverse events (AEs) following administration of ex-vivo expanded T cell products (antigen specific CTLs, allodepleted T cells and genetically modified T cells) on Investigational New Drug (IND) studies in our center. Results From 1998 to 2008, we infused 381 T cell products to 180 recipients, enrolled on 18 studies, receiving T cells targeting malignancies or post-transplant viral infections. There were no Grade 3-4 infusion reactions during initial monitoring or 24 hour follow-up. Twenty four mild (grade 1-2) adverse events (AEs) occurred in 21 infusions either during or immediately following infusion (up to 6 hours), most commonly nausea and vomiting (10/24; 41.6%), likely due to the DMSO cryoprotectant, and hypotension (20.8%), attributable to diphenhydramine pre-medication. 22 additional non-severe events were reported within 24 hours of infusion, most commonly culture negative fever, chills and nausea. Increased risk of adverse effects was associated with age (IRR 0.98; 95% CI 0.96-1.00; p=0.05), while an increase risk of immediate infusion-related events was higher in patients reporting allergies (IRR 2.72; 95% CI 1.00-7.40; p=0.05); sex, disease type or T cell source (allogeneic or autologous) had no effect on frequency of adverse events. Discussion Hence infusion of T cells is safe in the outpatient setting and associated with no severe reactions, so that monitoring for one hour after infusion is likely sufficient. As many of the AEs were attributable to diphenhydramine premedication, a lower dose (0.25mg/kg) should be selected. PMID:20429793

    Background Overweight and obesity are positively correlated with increased risk of morbidity and mortality. Aim To evaluate whether obesity may be considered an independent cardiovascular risk factor in patients of ages from 35 to 74 years followed-up for 10 years. Design of study Observational, longitudinal retrospective study. Setting Primary care practices in Badajoz (Spain). Method A cohort of 899 patients (mean 55.7 years; 58.2% female) without evidence of cardiovascular disease was studied. Results A total of 33.5% of the population were obese (body mass index ≥30 kg/m2). Patients meeting the obesity criteria were more commonly female (36.6%) and were older, had higher mean values of blood pressure and triglycerides, higher percentages of diabetes, and higher coronary risk using either the original Framingham or the Framingham function calibrated for the Spanish population (Framingham-REGICOR). During the follow-up period, the rates of cardiovascular events and death in patients with obesity tended to be higher: 16.3% versus 11.7%, P = 0.056 and 4.7% versus 2.2%, P<0.05, respectively. In the final model of the logistic regression multivariate analysis, the significant predictors of cardiovascular events in patients with obesity were age, sex (male), diastolic blood pressure, diabetes, and smoking. The highest odds ratio corresponded to smoking (odds ratio 2.03; 95% confidence interval = 1.22 to 3.38). Conclusion Obesity may not be considered an independent cardiovascular risk factor in patients aged from 35 to 74 years followed-up for 10 years. PMID:20822691

    Background— Immigrants from ethnic minority groups represent an increasing proportion of the population in many high-income countries, but little is known about the causes and amount of variation between various immigrant groups in the incidence of major cardiovascular events. Methods and Results— We conducted the Cardiovascular Health in Ambulatory Care Research Team (CANHEART) Immigrant Study, a big data initiative, linking information from Citizenship and Immigration Canada’s Permanent Resident database to 9 population-based health databases. A cohort of 824 662 first-generation immigrants aged 30 to 74 as of January 2002 from 8 major ethnic groups and 201 countries of birth who immigrated to Ontario, Canada between 1985 and 2000 were compared with a reference group of 5.2 million long-term residents. The overall 10-year age-standardized incidence of major cardiovascular events was 30% lower among immigrants than among long-term residents. East Asian immigrants (predominantly ethnic Chinese) had the lowest incidence overall (2.4 in males, 1.1 in females per 1000 person-years), but this increased with greater duration of stay in Canada. South Asian immigrants, including those born in Guyana, had the highest event rates (8.9 in males, 3.6 in females per 1000 person-years), along with immigrants born in Iraq and Afghanistan. Adjustment for traditional risk factors reduced but did not eliminate the differences in cardiovascular risk between various ethnic groups and long-term residents. Conclusions— Striking differences in the incidence of cardiovascular events exist among immigrants to Canada from different ethnic backgrounds. Traditional risk factors explain a part but not all of these differences. PMID:26324719

    Background/Aims Elevated lipoprotein(a) (Lp[a]) level is known to be a risk factor for cardiovascular disease (CVD). However, the data that has been reported on the association between the Lp(a) level and CVD in type 2 diabetes has been limited and incoherent. The aim of this study was to investigate the relationship between the Lp(a) concentration and new onset CVD in type 2 diabetes. Methods From March 2003 to December 2004, patients with type 2 diabetes without a prior history of CVD were consecutively enrolled. CVD was defined as the occurrence of coronary artery disease or ischemic stroke. Cox proportional hazards models were used to identify the associations between the Lp(a) and CVD after adjusting for confounding variables. Results Of the 1,183 patients who were enrolled, 833 participants were evaluated with a median follow-up time of 11.1 years. A total of 202 participants were diagnosed with CVD (24.2%). The median Lp(a) level for 1st and 4th quartile group was 5.4 (3.5 to 7.1) and 55.7 mg/dL (43.1 to 75.3). Compared with patients without CVD, those with CVD were older, had a longer duration of diabetes and hypertension, and used more insulin and angiotensin converting enzyme inhibitors/angiotensin receptor blockers at baseline. A Cox hazard regression analysis revealed that the development of CVD was significantly associated with serum Lp(a) level (hazard ratio, 1.92; 95% confidence interval [CI], 1.26 to 2.92; p < 0.001, comparing the 4th vs. 1st quartile of Lp[a]). Conclusions Elevated Lp(a) level was an independent predictable risk factor for CVD in type 2 diabetes. Other cardiovascular risk factors should be treated more intensively in type 2 diabetic patients with high Lp(a) levels. PMID:27756118

    Background Cardiovascular disease such as coronary artery disease, stroke and congestive heart failure, is a leading cause of death worldwide. A postulated risk factor is elevated circulating total homocysteine (tHcy) levels which is influenced mainly by blood levels of cyanocobalamin (vitamin B12), folic acid (vitamin B9) and pyridoxine (vitamin B6). There is uncertainty regarding the strength of association between tHcy and the risk of cardiovascular disease. Objectives To assess the clinical effectiveness of homocysteine-lowering interventions (HLI) in people with or without pre-existing cardiovascular disease. Search methods We searched The Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library (issue 3 2008), MEDLINE (1950 to August 2008), EMBASE (1988 to August 2008), and LILACS (1982 to September 2, 2008). We also searched in Allied and Complementary Medicine (AMED; 1985 to August 2008), ISI Web of Science (1993 to August 2008), and the Cochrane Stroke Group Specialised Register (April 2007). We hand searched pertinent journals and the reference lists of included papers. We also contacted researchers in the field. There was no language restriction in the search. Selection criteria We included randomised clinical trials (RCTs) assessing the effects of HLI for preventing cardiovascular events with a follow-up period of 1 year or longer. We considered myocardial infarction and stroke as the primary outcomes. We excluded studies in patients with end-stage renal disease. Data collection and analysis We independently performed study selection, risk of bias assessment and data extraction. We estimated relative risks (RR) for dichotomous outcomes. We measured statistical heterogeneity using I2. We used a random-effects model to synthesise the findings. Main results We included eight RCTs involving 24,210 participants with a low risk of bias in general terms. HLI did not reduce the risk of non-fatal or fatal myocardial infarction, stroke, or

    The Framingham Risk equation uses sex, age, smoking, total cholesterol, high-density lipoprotein (HDL) cholesterol and systolic blood pressure to predict 10-year risk of coronary heart disease (FR-10). The American Heart Association's Ideal Cardiovascular Health (IDEAL) score uses smoking, total cholesterol, fasting glucose, blood pressure, body mass index (BMI), diet, and physical activity to encourage a healthy cardiovascular phenotype. This study aimed to compare 6-month changes in the FR-10 vs. IDEAL score among young adults with BMI ≥25 to <40kg/m(2) enrolled in a behavioral weight loss intervention at the University of Pittsburgh (2010-12). Medians [25th, 75th percentiles] are reported. Weight decreased by 8kg [-12, -4] among 335 participants. Of 7 possible points, IDEAL score was 4 [3, 4] at baseline, improved (i.e., increased) by 1 [0, 2] over 6months, and improved in 64.2% and worsened in 6.6% of participants (p<0.001). IDEAL classification of BMI, physical activity, total cholesterol, blood pressure and glucose improved (all p<0.001), but not of smoking or diet (both p≥0.05). FR-10 was <1% at baseline for 88.1% of participants and changed in few participants (improved, i.e. decreased, in 7.5%, worsened in 1.8%, p<0.001). Among young adults with overweight or obesity enrolled in a weight loss intervention, IDEAL detected positive changes in a majority of participants while the FR-10 did not. These findings suggest that IDEAL score may be more sensitive to positive cardiovascular health changes resulting from a behavioral intervention in this population. PMID:26923555

FR-10 was <1% at baseline for 88.1% of participants and changed in few participants (improved, i.e. decreased, in 7.5%, worsened in 1.8%, p<0.001). Among young adults with overweight or obesity enrolled in a weight loss intervention, IDEAL detected positive changes in a majority of participants while the FR-10 did not. These findings suggest that IDEAL score may be more sensitive to positive cardiovascular health changes resulting from a behavioral intervention in this population.

    Abstract This article estimates the frequency of cardiovascular (CV) events that occurred after diagnosis in a large Spanish cohort of patients with systemic lupus erythematosus (SLE) and investigates the main risk factors for atherosclerosis. RELESSER is a nationwide multicenter, hospital-based registry of SLE patients. This is a cross-sectional study. Demographic and clinical variables, the presence of traditional risk factors, and CV events were collected. A CV event was defined as a myocardial infarction, angina, stroke, and/or peripheral artery disease. Multiple logistic regression analysis was performed to investigate the possible risk factors for atherosclerosis. From 2011 to 2012, 3658 SLE patients were enrolled. Of these, 374 (10.9%) patients suffered at least a CV event. In 269 (7.4%) patients, the CV events occurred after SLE diagnosis (86.2% women, median [interquartile range] age 54.9 years [43.2–66.1], and SLE duration of 212.0 months [120.8–289.0]). Strokes (5.7%) were the most frequent CV event, followed by ischemic heart disease (3.8%) and peripheral artery disease (2.2%). Multivariate analysis identified age (odds ratio [95% confidence interval], 1.03 [1.02–1.04]), hypertension (1.71 [1.20–2.44]), smoking (1.48 [1.06–2.07]), diabetes (2.2 [1.32–3.74]), dyslipidemia (2.18 [1.54–3.09]), neurolupus (2.42 [1.56–3.75]), valvulopathy (2.44 [1.34–4.26]), serositis (1.54 [1.09–2.18]), antiphospholipid antibodies (1.57 [1.13–2.17]), low complement (1.81 [1.12–2.93]), and azathioprine (1.47 [1.04–2.07]) as risk factors for CV events. We have confirmed that SLE patients suffer a high prevalence of premature CV disease. Both traditional and nontraditional risk factors contribute to this higher prevalence. Although it needs to be verified with future studies, our study also shows—for the first time—an association between diabetes and CV events in SLE patients. PMID:26200625

    Objectives: The association between educational status and 10-year risk for acute coronary syndrome (ACS) and all-cause mortality was evaluated. Methods: From October 2003 to September 2004, 2172 consecutive ACS patients from six Greek hospitals were enrolled. In 2013 to 2014, a 10-year follow-up (2004-2014) assessment was performed for 1918 participants (participation rate, 88%). Each patient’s educational status was classified as low (<9 years of school), intermediate (9 to 14 years), or high (>14 years). Results: Overall all-cause mortality was almost twofold higher in the low-education group than in the intermediate-education and high-education groups (40% vs. 22% and 19%, respectively, p<0.001). Additionally, 10-year recurrent ACS events (fatal and non-fatal) were more common in the low-education group than in the intermediate-education and high-education groups (42% vs. 30% and 35%, p<0.001), and no interactions between sex and education on the investigated outcomes were observed. Moreover, patients in the high-education group were more physically active, had a better financial status, and were less likely to have hypertension, diabetes, or ACS than the participants with the least education (p<0.001); however, when those characteristics and lifestyle habits were accounted for, no moderating effects regarding the relationship of educational status with all-cause mortality and ACS events were observed. Conclusions: A U-shaped association may be proposed for the relationship between ACS prognosis and educational status, with participants in the low-education and high-education groups being negatively affected by other factors (e.g., job stress, depression, or loneliness). Public health policies should be aimed at specific social groups to reduce the overall burden of cardiovascular disease morbidity. PMID:27499164

    Dietary fat is normally in TAG form, but diacylglycerol (DAG) is a natural component of edible oils. Studies have shown that consumption of DAG results in metabolic characteristics that are distinct from those of TAG, which may be beneficial in preventing and managing obesity. The objective of the present study was to investigate if food items in which part of the TAG oil is replaced with DAG oil combined with high α-linolenic acid (ALA) content would influence metabolic markers. A 12-week double-blinded randomised controlled parallel-design study was conducted. The participants (n 23) were healthy, overweight men and women, aged 37-67 years, BMI 27-35 kg/m(2), with waist circumference >94 cm (men) and >88 cm (women). The two groups received 20 g margarine, 11 g mayonnaise and 12 g oil per d, containing either high ALA and sn-1,3-DAG or high ALA and TAG. Substitution of TAG oil with DAG oil in food items for 12 weeks led to an improvement of the predicted 10 years cardiovascular risk score in overweight subjects by non-significantly improving markers of health such as total body fat percentage, trunk fat mass, alanine aminotransferase, systolic blood pressure, γ-glutamyl transferase, alkaline phosphatase and total fat-free mass. This may suggest that replacing TAG oil with DAG oil in healthy, overweight individuals may have beneficial metabolic effects.

    In recent years cardiovascular diseases were the second most common cause of death worldwide. Therefore, the consumption of cardiovascular drugs is high, which might result in an increase of them in the environment. The major source of aquatic environmental contamination is still effluents of wastewater treatment plants (WWTPs). Unfortunately removal of cardiovascular active compounds and/or their metabolites in WWTP is still unsatisfactory. Among microbial and abiotic degradation of these compounds during wastewater processes, photolysis and photodegradation of cardiovascular drugs also play an important role. New formed compounds may be more toxic or retain the properties of parent compounds. Thus the main goal of this paper was to provide a detailed and comprehensive review of used analytical methods, coupled to liquid chromatography-tandem mass spectrometry, to determine the presence of cardiovascular compounds in surface waters as well as WTTPs effluents and influents. Exhaustive preparation for mass spectrometry detection and quantitation including samples pre-treatment, and the common problem of the matrix effect are thoroughly explored in this paper. Additionally, the article provides some hints in respect of recently noted problematic issue related to the availability of specific standards for the analysis of drug's metabolites. Furthermore, information concerning the metabolism of cardiovascular active compounds including differences in metabolism within enantiomers is described. This article also touches on the problems associated with environmental risk assessment due to the presence of cardiovasculars in the environment. The paper also tries to explain differences in concentrations among cardiovascular compounds between countries worldwide.

    Summary Background and objectives Circulating fibroblast growth factor-23 is associated with adverse cardiovascular outcomes in CKD and non-CKD individuals, but the underlying mechanism remains unclear. This study tested whether this association is independent of mineral metabolism and indices of subclinical cardiovascular pathology. Design, setting, participants, & measurements The prospective association between fibroblast growth factor-23 and major cardiovascular events (a composite of hospital-treated myocardial infarction, hospital-treated stroke, or all-cause mortality) was investigated in the community-based Prospective Investigation of the Vasculature in Uppsala Seniors (n=973; mean age=70 years, 50% women) using multivariate logistic regression. Subjects were recruited between January of 2001 and June of 2004. Results During follow-up (median=5.1 years), 112 participants suffered a major cardiovascular event. In logistic regression models adjusted for age, sex, and estimated GFR, higher fibroblast growth factor-23 was associated with increased risk for major cardiovascular events (odds ratio for tertiles 2 and 3 versus tertile 1=1.92, 95% confidence interval=1.19–3.09, P<0.01). After additional adjustments in the model, adding established cardiovascular risk factors, confounders of mineral metabolism (calcium, phosphate, parathyroid hormone, and 25(OH)-vitamin D), and indices of subclinical pathology (flow-mediated vasodilation, endothelial-dependent and -independent vasodilation, arterial stiffness, and atherosclerosis and left ventricular mass) attenuated this relationship, but it remained significant (odds ratio for tertiles 2 and 3 versus tertile 1=1.69, 95% confidence interval=1.01–2.82, P<0.05). Conclusions Fibroblast growth factor-23 is an independent predictor of cardiovascular events in the community, even after accounting for mineral metabolism abnormalities and subclinical cardiovascular damage.

    Marijuana is one of the most widely used recreational substances in the world, considered by many consumers as a relatively safe drug with few significant side-effects. We report the case of a 21-year-old man who suffered an acute myocardial infarction following the use of marijuana, despite having no other identifiable risk factors for an acute cardiovascular event. We review the published medical literature regarding acute cardiovascular events following marijuana use and postulate a possible mechanism for this unusual pathological consequence of marijuana use.

    Objective The binding protein FKBP5 is an important modulator of the function of the glucocorticoid receptor, the main receptor of the stress horm one system. This turns the FKBP5 gene into a key candidate for gene-environment interactions, which are considered critical for pathogenesis of stress-related disorders. The authors explored gene-environment interactions between FKBP5 gene variants and adverse life events in predicting the first occurrence of a major depressive episode. Method The analyses were based on 884 Caucasians in a 10-year prospective community study. At baseline, they were 14–24 years old and did not fulfill criteria for a major depressive episode. The DSM-IV-based Munich Composite International Diagnostic Interview was used to assess adverse life events preceding baseline and major depressive episodes during follow-up. On the basis of previous findings, five single-nucleotide polymorphisms (SNPs) within the FKBP5 gene were selected for genotyping. Results While the authors did not observe genetic main effects, they found interactions between the five SNPs and traumatic (but not separation) events, with the strongest effect for severe trauma. The effect of trauma on incident major depressive episodes was evident among subjects homozygous for the minor alleles but not subjects with other genotypes. The findings were replicated in the U.K. Environmental Risk Longitudinal Twin Study. Conclusions These hypothesis-driven results suggest that an interaction between FKBP5 genotype and trauma is involved in the onset of depression. Subjects homozygous for the minor alleles of the investigated FKBP5 SNPs seem to be particularly sensitive to effects of trauma exposure in terms of triggering depression onset. PMID:21865530

Our results indicate that the effects of fire and disturbance on invertebrate communities are difficult to detect 10-years post event. Resilience in the invertebrate community and a flexible diet may be contributing to the resilience of resident trout found throughout our study streams. However, geomorphic changes and habitat alterations caused by massive channel-reorganizing events after wildfire may prevent full invertebrate community recovery for some time after the disturbance.

    Background Obstructive sleep apnea is associated with an increased risk of cardiovascular events; whether treatment with continuous positive airway pressure (CPAP) prevents major cardiovascular events is uncertain. Methods After a 1-week run-in period during which the participants used sham CPAP, we randomly assigned 2717 eligible adults between 45 and 75 years of age who had moderate-to-severe obstructive sleep apnea and coronary or cerebrovascular disease to receive CPAP treatment plus usual care (CPAP group) or usual care alone (usual-care group). The primary composite end point was death from cardiovascular causes, myocardial infarction, stroke, or hospitalization for unstable angina, heart failure, or transient ischemic attack. Secondary end points included other cardiovascular outcomes, health-related quality of life, snoring symptoms, daytime sleepiness, and mood. Results Most of the participants were men who had moderate-to-severe obstructive sleep apnea and minimal sleepiness. In the CPAP group, the mean duration of adherence to CPAP therapy was 3.3 hours per night, and the mean apnea-hypopnea index (the number of apnea or hypopnea events per hour of recording) decreased from 29.0 events per hour at baseline to 3.7 events per hour during follow-up. After a mean follow-up of 3.7 years, a primary end-point event had occurred in 229 participants in the CPAP group (17.0%) and in 207 participants in the usual-care group (15.4%) (hazard ratio with CPAP, 1.10; 95% confidence interval, 0.91 to 1.32; P=0.34). No significant effect on any individual or other composite cardiovascular end point was observed. CPAP significantly reduced snoring and daytime sleepiness and improved health-related quality of life and mood. Conclusions Therapy with CPAP plus usual care, as compared with usual care alone, did not prevent cardiovascular events in patients with moderate-to-severe obstructive sleep apnea and established cardiovascular disease.

    Background There is a paucity of data describing cardiovascular events after tornado outbreaks. We proposed to study the effects of tornadoes on the incidence of cardiovascular events at a tertiary care institution. Population and methods Hospital admission records from a single center situated in a tornado-prone area three months before and after a 2013 tornado outbreak were abstracted. To control for seasonal variation, we also abstracted data from the same period of the prior year (control). Hospital admissions for cardiovascular events (CVEs) including acute myocardial infarction, stroke and venous thromboembolism (VTE) were summated by zip codes, and compared by time period. Results There were 22,607 admissions analyzed, of which 6,705 (30%), 7,980 (35%), and 7,922 (35%) were during the pre-tornado, post-tornado, and control time frames, respectively. There were 344 CVE in the controls, 317 CVE in pre-tornado and 364 CVEs in post tornado periods. There was no difference in the prevalence of CVE during the post-tornado season compared with the control (PPR = 1.05 95% CI: 0.91 to 1.21, p = 0.50) or the pre-tornado season (PPR= 0.96, 95% CI: 0.83 to 1.21, p = 0.63). Conclusion In conclusion, tornado outbreaks did not increase the prevalence of cardiovascular events. In contrast to the effect of hurricanes, implementation of a healthcare policy change directed toward the early treatment and prevention of cardiovascular events after tornadoes does not seem warranted.

    Fluvial geomorphological processes evolve the landscape and are often referred to as processes that act for hundred to thousands of years before making a noticeable change in landforms. For the Indus River, landscape evolution has been intensified due to human interference. Failure in repairing its levees from previous floods led in July 2010 during a not exceptional discharge event (~10 year recurrence interval) to a large avulsion and flooding disaster that caused ~2,000 fatalities. Examining pre- and post flood maps by analyzing MODIS and ASTER-A1 data allowed us to determine the extent of sandy flood deposits and to quantify channel migration patterns. The typical pattern of inner bend deposition (due to helical flow) and outer bend erosion were less pronounced. We hypothesize that when flow exceeds bankfull conditions, deposition is more uniform and no longer constrained by the streambed geometry. We observe that the inner and the outer river bend receive similar amounts of sandy deposits (43% versus 57% respectively). Crevasse splaying was widespread and appeared to occur as a flow stripping process again both upon the point bars as well as in river outer bends. Channel activity (defined as the areal shift of the pre- and post river centerline), sinuosity, slope and lateral sediment deposition were determined for 50km river stretches. Analyzes reveal that flood deposits extend generally less than 2 km from the main channel axis. Furthermore, channel activity correlates negatively with channel sinuosity and lateral distance of sediment deposition and positively with slope. The river channel migrated over 100's of meters during the July 2010 flood event. Lateral migration averaged ~340m along a 1000km stretch of the Indus River over a period of just 52 days. Although this discharge event was not exceptional, lateral migration was significant and deposition impacts the active river floodplain. Remarkably, most sediments are deposited downstream the large

    Background. Hypertensive haemodialysis patients may be at a high risk for cardiovascular events. This study was undertaken to ascertain whether the calcium channel blocker amlodipine reduces mortality and cardiovascular events in these high-risk patients. Methods. We evaluated the effects of amlodipine on cardiovascular events in 251 hypertensive haemodialysis patients in an investigator-designed, prospective, randomized, double-blind, placebo-controlled, multicenter trial. One hundred and twenty-three patients were randomly assigned to amlodipine (10 mg once daily) and 128 to placebo. The primary endpoint was mortality from any cause. The secondary endpoint was a composite variable consisting of mortality from any cause or cardiovascular event. Analysis was by intention-to-treat. The trial was registered with ClinicalTrials.gov (number NCT00124969). Results. The median age of patients was 61 years (25% percentile − 75% percentile, 47–69), and the median follow-up was 19 months (8–30). Fifteen (12%) of the 123 patients assigned to amlodipine and 22 (17%) of the 128 patients assigned to placebo had a primary endpoint [hazard ratio 0.65 (95% CI 0.34–1.23); P = 0.19]. Nineteen (15%) of the 123 haemodialysis patients assigned to amlodipine and 32 (25%) of the 128 haemodialysis patients assigned to placebo reached the secondary composite endpoint [hazard ratio 0.53 (95% CI 0.31–0.93); P = 0.03]. Conclusion. Amlodipine safely reduces systolic blood pressure and it may have a beneficial effect on cardiovascular outcomes in hypertensive haemodialysis patients. PMID:18511605

    This study evaluates the prognostic value of stress echocardiography (Secho) in short-term (10 years) and lifetime atherosclerotic cardiovascular disease risk-defined groups according to the American College of Cardiology/American Heart Association 2013 cardiovascular risk calculator. The ideal risk assessment and management of patients with low-to-intermediate or high short-term versus low (<39%) or high (≥39%) lifetime CV risk is unclear. The purpose of this study was to evaluate the prognostic value of Secho in short-term and lifetime CV risk-defined groups. We evaluated 4,566 patients (60 ± 13 years; 46% men) who underwent Secho (41% treadmill and 59% dobutamine) with low-intermediate short-term (<20%) risk divided into low (<39%, n = 368) or high (≥39%, n = 661) lifetime CV risk and third group with high short-term risk (≥20%, n = 3,537). Follow-up (3.2 ± 1.5 years) for nonfatal myocardial infarction (n = 102) and cardiac death (n = 140) were obtained. By univariate analysis, age (p <0.001) and ≥3 new ischemic wall motion abnormalities (WMAs, p <0.001) were significant predictors of cardiac events. Cumulative survival in patients was significantly worse in patients with ≥3 WMA versus <3 WMA in low-intermediate short-term and low (3.3% vs 0.3% per year, p <0.001) or high (2.0% vs 0% per year, p <0.001) lifetime risk and also in those with high short-term CV risk group (3.5% vs 1.0% per year, p <0.001). Multivariate Cox proportional hazards analysis identified ≥3 new ischemic WMAs as the strongest predictor of cardiac events (hazard ratio 3.0, 95% confidence interval 2.3 to 3.9, p <0.001). In conclusion, Secho results (absence or presence of ≥3 new ischemic segments) can further refine risk assessment in patients with low-intermediate or high short-term versus low or high lifetime cardiovascular risk. Event rate with normal Secho is low (≤1% per year) but higher in patients with high short-term CV risk by the American College of

  13. Role of antiplatelet drugs in the prevention of cardiovascular events.

    Antiplatelet drugs have an established place in the prevention of vascular events in a variety of clinical conditions, such as myocardial infarction, stroke and cardiovascular death. Both European and American guidelines recommend the use of antiplatelet drugs in patients with established coronary heart disease and other atherosclerotic disease. In high-risk patients, such as those with post-acute myocardial infarction (AMI), ischaemic stroke or transient ischaemic attack, and in patients with stable or unstable angina, peripheral arterial occlusive disease or atrial fibrillation, antiplatelet treatment may reduce the risk of a serious cardiovascular event by approximately 25%, including reduction of non-fatal myocardial infarction by 1/6, non-fatal stroke by 1/4 and cardiovascular death by 1/6. Some data indicate that antiplatelet drugs may also have a role in primary prevention. In people who are aged over 65 years, or have hypertension, hypercholesterolaemia, diabetes, obesity or familial history of myocardial infarction at young age, aspirin may reduce both cardiovascular deaths and total cardiovascular events. Aspirin has been studied and used most extensively. It may exert its beneficial effect not only by acting on platelets, but also by other mechanisms, such as preventing thromboxane A2 (TXA2)-induced vasoconstriction or reducing inflammation. Indeed, experimental data show that low-dose aspirin may suppress vascular inflammation and thereby increase the stability of atherosclerotic plaque. Moreover, in human studies, aspirin seems to be most effective in those with elevated C-reactive protein levels. Vascular events, however, do occur despite aspirin administration. This may be due to platelet activation by pathways not blocked by aspirin, intake of drugs that interfere with aspirin effect or aspirin resistance. In the CAPRIE (Clopidogrel vs. Aspirin in Patients at Risk of Ischaemic Events) study, long-term clopidogrel administered to patients with

    Androgen excess (AE) was approximated to be present in 7% of the adult population of women. Polycystic ovary syndrome (PCOS) is the most prevalent among them, followed by idiopathic hirsutism (IH), congenital adrenal hyperplasia (CAH), hyperandrogenic insulin-resistant acanthosis nigricans (HAIRAN) syndrome, and androgen-secreting neoplasms (ASNs). Increased cardiovascular risk was implicated in women with AE. Serum testosterone independently increases risk for cardiovascular disease (CVD), and correlates even with indices of subclinical atherosclerosis in various populations of postmenopausal women. Hyperandrogenism in PCOS is closely related to the aggravation of abdominal obesity, and together with insulin resistance forming the metabolic core for the development of CVD. However, phenotypic variability of PCOS generates significant influence on the cardiometabolic risks. Numerous risk factors in PCOS lead to 5-7 times higher risk for CVD and over 2-fold higher risk for coronary heart disease and stroke. However, issue on the cardiometabolic risk in postmenopausal women with hyperandrogenic history is still challenging. There is a significant overlapping in the CVD characteristics of women with PCOS and variants of CAH. Relevant clinical data on the prevalence and cardiometabolic risk and events in women with IH, HAIRAN syndrome or ASNs are scarce. The effects of various oral contraceptives (OCs) and antiandrogenic compounds on metabolic profile are varying, and could be related to the selected populations and different therapy regiments mainly conducted in women with PCOS. It is assumed relation of OCs containing antiandrogenic progestins to the increased risk of cardiovascular and thromboembolic events.

    BACKGROUND Prolonged lowering of blood pressure after a stroke reduces the risk of recurrent stroke. In addition, inhibition of the renin–angiotensin system in high-risk patients reduces the rate of subsequent cardiovascular events, including stroke. However, the effect of lowering of blood pressure with a renin–angiotensin system inhibitor soon after a stroke has not been clearly established. We evaluated the effects of therapy with an angiotensin-receptor blocker, telmisartan, initiated early after a stroke. METHODS In a multicenter trial involving 20,332 patients who recently had an ischemic stroke, we randomly assigned 10,146 to receive telmisartan (80 mg daily) and 10,186 to receive placebo. The primary outcome was recurrent stroke. Secondary outcomes were major cardiovascular events (death from cardiovascular causes, recurrent stroke, myocardial infarction, or new or worsening heart failure) and new-onset diabetes. RESULTS The median interval from stroke to randomization was 15 days. During a mean followup of 2.5 years, the mean blood pressure was 3.8/2.0 mm Hg lower in the telmisartan group than in the placebo group. A total of 880 patients (8.7%) in the telmisartan group and 934 patients (9.2%) in the placebo group had a subsequent stroke (hazard ratio in the telmisartan group, 0.95; 95% confidence interval [CI], 0.86 to 1.04; P = 0.23). Major cardiovascular events occurred in 1367 patients (13.5%) in the telmisartan group and 1463 patients (14.4%) in the placebo group (hazard ratio, 0.94; 95% CI, 0.87 to 1.01; P = 0.11). New-onset diabetes occurred in 1.7% of the telmisartan group and 2.1% of the placebo group (hazard ratio, 0.82; 95% CI, 0.65 to 1.04; P = 0.10). CONCLUSIONS Therapy with telmisartan initiated soon after an ischemic stroke and continued for 2.5 years did not significantly lower the rate of recurrent stroke, major cardiovascular events, or diabetes.

    Cardiovascular disease (CVD) is the major cause of death globally. More people die of CVDs each year than from any other disease. Over 80% of CVD deaths occur in low and middle income countries and occur almost equally in male and female. In this paper, different computational models based on Bayesian Networks, Multilayer Perceptron,Radial Basis Function and Logistic Regression methods are presented to predict early risk detection of the cardiovascular event. A total of 929 (626 male and 303 female) heart attack data are used to construct the models.The models are tested using combined as well as separate male and female data. Among the models used, it is found that the Multilayer Perceptron model yields the best accuracy result.

    BACKGROUND Major depression or deterioration of previous mood disorders is a common adverse consequence of coronary heart disease, heart failure, and cardiac revascularization procedures. Therefore, treatment of depression is expected to result in improvement of mood condition in these patients. Despite demonstrated effects of anti-depressive treatment in heart disease patients, the use of some antidepressants have shown to be associated with some adverse cardiac and non-cardiac events. In this narrative review, the authors aimed to first assess the findings of published studies on beneficial and also harmful effects of different types of antidepressants used in patients with heart diseases. Finally, a new categorization for selecting antidepressants according to their cardiovascular effects was described. METHODS Using PubMed, Web of Science, SCOPUS, Index Copernicus, CINAHL, and Cochrane Database, we identified studies designed to evaluate the effects of depression and also using antidepressants on cardiovascular outcome. A 40 studies were finally assessed systematically. Among those eligible studies, 14 were cohort or historical cohort studies, 15 were randomized clinical trial, 4 were retrospective were case-control studies, 3 were meta-analyses and 2 animal studies, and 2 case studies. RESULTS According to the current review, we recommend to divide antidepressants into three categories based on the severity of cardiovascular adverse consequences including (1) the safest drugs including those drugs with cardio-protective effects on ventricular function, as well as cardiac conductive system including selective serotonin reuptake inhibitors, (2) neutralized drugs with no evidenced effects on cardiovascular system including serotonin-norepinephrine reuptake inhibitors, and (3) harmful drugs with adverse effects on cardiac function, hemodynamic stability, and heart rate variability including tricyclic antidepressants, serotonin antagonist and reuptake inhibitors

    Background Premature cardiovascular disease limits the duration and quality of life on long‐term hemodialysis. The objective of this study was to define the frequency of fatal and nonfatal cardiovascular events attributable to atherosclerotic and nonatherosclerotic mechanisms, risk factors for these events, and the effects of cinacalcet, using adjudicated data collected during the EValuation of Cinacalcet HCl Therapy to Lower CardioVascular Events (EVOLVE) Trial. Methods and Results EVOLVE was a randomized, double‐blind, placebo‐controlled clinical trial that randomized 3883 hemodialysis patients with moderate to severe secondary hyperparathyroidism to cinacalcet or matched placebo for up to 64 months. For this post hoc analysis, the outcome measure was fatal and nonfatal cardiovascular events reflecting atherosclerotic and nonatherosclerotic cardiovascular diseases. During the trial, 1518 patients experienced an adjudicated cardiovascular event, including 958 attributable to nonatherosclerotic disease. Of 1421 deaths during the trial, 768 (54%) were due to cardiovascular disease. Sudden death was the most frequent fatal cardiovascular event, accounting for 24.5% of overall mortality. Combining fatal and nonfatal cardiovascular events, randomization to cinacalcet reduced the rates of sudden death and heart failure. Patients randomized to cinacalcet experienced fewer nonatherosclerotic cardiovascular events (adjusted relative hazard 0.84, 95% CI 0.74 to 0.96), while the effect of cinacalcet on atherosclerotic events did not reach statistical significance. Conclusions Accepting the limitations of post hoc analysis, any benefits of cinacalcet on cardiovascular disease in the context of hemodialysis may result from attenuation of nonatherosclerotic processes.

    Smoking continues to be the leading cause of preventable deaths in the USA, accounting for one in every five deaths every year, and cardiovascular (CV) disease remains the leading cause of those deaths. Hence, there is increasing awareness to quit smoking among the public and counseling plays an important role in smoking cessation. There are different pharmacological methods to help quit smoking that includes nicotine replacement products available over the counter, including patch, gum, and lozenges, to prescription medications, such as bupropion and varenicline. There have been reports of both nonserious and serious adverse CV events associated with the use of these different pharmacological methods, especially varenicline, which has been gaining media attention recently. Therefore, we systematically reviewed the various pharmacotherapies used in smoking cessation and analyzed the evidence behind these CV events reported with these therapeutic agents.

    Periodontitis, the main cause of tooth loss in the middle-aged and elderly, associates with the risk of atherosclerotic vascular disease. The objective was to study the capability of the number of missing teeth in predicting incident cardiovascular diseases (CVDs), diabetes, and all-cause death. The National FINRISK 1997 Study is a Finnish population-based survey of 8,446 subjects with 13 y of follow-up. Dental status was recorded at baseline in a clinical examination by a trained nurse, and information on incident CVD events, diabetes, and death was obtained via national registers. The registered CVD events included coronary heart disease events, acute myocardial infarction, and stroke. In Cox regression analyses, having ≥5 teeth missing was associated with 60% to 140% increased hazard for incident coronary heart disease events (P < 0.020) and acute myocardial infarction (P < 0.010). Incident CVD (P < 0.043), diabetes (P < 0.040), and death of any cause (P < 0.019) were associated with ≥9 missing teeth. No association with stroke was observed. Adding information on missing teeth to established risk factors improved risk discrimination of death (P = 0.0128) and provided a statistically significant net reclassification improvement for all studied end points. Even a few missing teeth may indicate an increased risk of CVD, diabetes, or all-cause mortality. When individual risk factors for chronic diseases are assessed, the number of missing teeth could be a useful additional indicator for general medical practitioners.

    Background Microvascular and macrovascular complications in diabetes stem from chronic hyperglycemia and are thought to have overlapping pathophysiology. The aim of this study was to investigate the incidence rate of hospitalized myocardial infarctions (MI) and cerebrovascular accidents (CVA) in patients with diabetic macular edema (DME) compared with diabetic patients without retinal diseases. Methods This was a retrospective cohort study of a commercially insured population in an administrative claims database. DME subjects (n = 3519) and diabetes controls without retinal disease (n = 10557) were matched by age and gender. Healthcare claims were analyzed for the study period from 1 January 2002 to 31 December 2005. Incidence and adjusted rate ratios of hospitalized MI and CVA events were then calculated. Results The adjusted rate ratio for MI was 2.50 (95% CI: 1.83-3.41, p < 0.001) for DME versus diabetes controls. Predictors of MI events were heart disease, history of acute MI, and prior use of antiplatelet or anticoagulant drugs. The adjusted rate ratio for CVA was 1.98 (95% CI: 1.39-2.83, p < 0.001) for DME versus diabetes controls. Predictors of CVA events were cardiac arrhythmia, Charlson comorbidity scores, history of CVA, hyperlipidemia, and other cerebrovascular diseases. Conclusion Event rates of MI or CVA were higher in patients with DME than in diabetes controls. This study is one of few with sufficient sample size to accurately estimate the relationship between DME and cardiovascular outcomes. PMID:22646811

    Hypertension in pregnancy is a risk factor for future hypertension and cardiovascular disease. This may reflect an underlying familial predisposition or persistent damage caused by the hypertensive pregnancy. We sought to isolate the effect of hypertension in pregnancy by comparing the risk of hypertension and cardiovascular disease in women who had hypertension in pregnancy and their sisters who did not using the dataset from the Genetic Epidemiology Network of Arteriopathy study, which examined the genetics of hypertension in white, black, and Hispanic siblings. This analysis included all sibships with at least one parous woman and at least one other sibling. After gathering demographic and pregnancy data, BP and serum analytes were measured. Disease-free survival was examined using Kaplan-Meier curves and Cox proportional hazards regression. Compared with their sisters who did not have hypertension in pregnancy, women who had hypertension in pregnancy were more likely to develop new onset hypertension later in life, after adjusting for body mass index and diabetes (hazard ratio 1.75, 95% confidence interval 1.27-2.42). A sibling history of hypertension in pregnancy was also associated with an increased risk of hypertension in brothers and unaffected sisters, whereas an increased risk of cardiovascular events was observed in brothers only. These results suggest familial factors contribute to the increased risk of future hypertension in women who had hypertension in pregnancy. Further studies are needed to clarify the potential role of nonfamilial factors. Furthermore, a sibling history of hypertension in pregnancy may be a novel familial risk factor for future hypertension.

    A variety of systemic inflammatory rheumatic diseases associate with an increased risk of atherosclerotic events and premature cardiovascular (CV) disease. Although this recognition has stimulated intense basic science and clinical research, the precise nature of the relationship between local and systemic inflammation, their interactions with traditional CV risk factors, and their role in accelerating atherogenesis remains unresolved. The individual rheumatic diseases have both shared and unique attributes that might impact CV events. Understanding of the positive and negative influences of individual anti-inflammatory therapies remains rudimentary. Clinicians need to adopt an evidence-based approach to develop diagnostic techniques to identify those rheumatologic patients most at risk of CV disease and to develop effective treatment protocols. Development of optimal preventative and disease-modifying approaches for atherosclerosis in these patients will require close collaboration between basic scientists, CV specialists, and rheumatologists. This interface presents a complex, important, and exciting challenge. PMID:25433021

    Purpose To estimate the proportion of osteoporosis patients in whom initiating strontium ranelate treatment, under new EMA guidelines, should be contraindicated because of a history of cardiovascular events or risk for cardiovascular events. Materials and methods This was a retrospective analysis of medical and pharmacy claims using the Clinical Practice Research Datalink database. Patients were included if they had ≥1 prescription of strontium from September 1, 2008 to August 31, 2013, were aged ≥50 as of the index date (the date of the first ever strontium ranelate prescription), and had ≥1 year of medical records pre-index. Cardiovascular events occurring any time pre-index were identified, which included ischemic heart disease, cerebrovascular disease, uncontrolled hypertension, and peripheral arterial disease. Cardiovascular risk factors assessed included 1) diabetes or hypertension any time pre-index; 2) hyperlipidemia in the 12 months pre-index; or 3) obesity in the 12 months pre-index. Results A total of 7,474 patients were included: 90.4% were women, with an average age of 76.5 years, and 84.5% used osteoporosis therapy, either bisphosphonates or non-bisphosphonates, prior to strontium initiation. A total of 23.6% of patients experienced ≥1 cardiovascular event prior to strontium initiation; the rate was lower among female patients than in male patients (22.4% vs 35.3%, P<0.01). A total of 45.9% had risk factors for cardiovascular events (without cardiovascular event history). Conclusion More than one-fifth of osteoporosis patients in the UK who used strontium had a cardiovascular event history, and one-half had cardiovascular risk factors prior to strontium initiation.

    Traffic noise and air pollution have been associated with cardiovascular health effects. Until date, only a limited amount of prospective epidemiological studies is available on long-term effects of road traffic noise and combustion related air pollution. This study investigates the relationship between road traffic noise and air pollution and hospital admissions for ischemic heart disease (IHD: International Classification of Diseases (ICD9) 410-414) or cerebrovascular disease (cerebrovascular event [CVE]: ICD9 430-438). We linked baseline questionnaire data to 13 years of follow-up on hospital admissions and road traffic noise and air pollution exposure, for a large random sample (N = 18,213) of inhabitants of the Eindhoven region, Netherlands. Subjects with cardiovascular event during follow-up on average had higher road traffic noise day, evening, night level (L den) and air pollution exposure at the home. After adjustment for confounders (age, sex, body mass index, smoking, education, exercise, marital status, alcohol use, work situation, financial difficulties), increased exposure did not exert a significant increased risk of hospital admission for IHD or cerebrovascular disease. Relative risks (RRs) for a 5 (th) to 95 (th) percentile interval increase were 1.03 (0.88-1.20) for L den; 1.04 (0.90-1.21) for particulate matter (PM 10 ); 1.05 (0.91-1.20) for elemental carbon (EC); and 1.12 (096-1.32) for nitrogen dioxide (NO 2 ) in the full model. While the risk estimate seemed highest for NO 2 , for a 5 (th) to 95 (th) percentile interval increase, expressed as RRs per 1 μg/m 3 increases, hazard ratios seemed highest for EC (RR 1.04 [0.92-1.18]). In the subgroup of study participants with a history of cardiovascular disease, RR estimates seemed highest for noise exposure (1.19 [0.87-1.64] for L den); in the subgroup of elderly RR seemed highest for air pollution exposure (RR 1.24 [0.93-1.66] for NO 2 ).

    Cardiovascular and cerebrovascular disease (CCVD) are major causes of morbidity and mortality among patients with diabetes. Strict control of treatable risk factors that contribute to atherosclerosis is important to reduce the risk of stroke, myocardial infarction, and peripheral arterial disease. Simultaneous pancreas-kidney transplantation (SPKT) may significantly improve these risk factors in patients with type 1 diabetes. We studied 103 SPKT from our center with both organs functioning for metabolic and hypertensive control; body mass index (BMI); immunosuppression; and CCVD events. The 53 females/50 males showed a mean age of 35 ± 6 years, diabetes for 24 ± 6 years, and on dialysis for 31 ± 23 months. The follow-up ranged from 6-142 months. Mean value of last creatinine clearance was 76 ± 24 mL/min, all 103 SPKT were insulin-independent with mean glycemia = 81 ± 10 mg/dL and hemoglobin A1c (HbA1c) = 5.3% ± 0.4%. All of them were under tacrolimus treatment; 9.7% also with sirolimus but 67% steroid-free. According to the National Cholesterol Education Program Adult Treatment Panel 3 criteria, 4 patients showed a fasting glucose > 100 mg/dL; only one, HbA1c > 5.6%. Hypertension was recorded in 38.5%; low high-density lipoprotein cholesterol in 19.4%; hypertriglyceridemia in 7.8%; BMI > 30% in only 2 patients; 21.4% were prescribed statins. We registered cardiovascular events in 7 patients (6.8%). Patients with steroid treatment showed higher triglycerides (122 ± 53 vs 90 ± 36 mg/dL; P = .001) and more often tended to be hypertensive (41.2% vs 37.7%, P = .073) compared with those free of these drugs. Hypertension was associated with an higher BMI (24.1 ± 2.8 vs 22.3 ± 2.9 kg/m(2), P = .002). BMI > 25% was associated with higher total cholesterol (195 ± 47 vs 169 ± 28 mg/dL, P = .015) and low-density lipoprotein cholesterol (116 ± 40 vs 96 ± 27 mg/dL, P = .003).

    Background and Objectives Some evidence suggests that bisphosphonates may reduce atherosclerosis, while concerns have been raised about atrial fibrillation. We conducted a meta-analysis to determine the effects of bisphosphonates on total adverse cardiovascular (CV) events, atrial fibrillation, myocardial infarction (MI), stroke, and CV death in adults with or at risk for low bone mass. Methods A systematic search of MEDLINE and EMBASE through July 2014 identified 58 randomized controlled trials with longer than 6 months in duration that reported CV events. Absolute risks and the Mantel-Haenszel fixed-effects odds ratios (ORs) and 95% confidence intervals (CIs) of total CV events, atrial fibrillation, MI, stroke, and CV death were estimated. Subgroup analyses by follow-up duration, population characteristics, bisphosphonate types, and route were performed. Results Absolute risks over 25–36 months in bisphosphonate-treated versus control patients were 6.5% versus 6.2% for total CV events; 1.4% versus 1.5% for atrial fibrillation; 1.0% versus 1.2% for MI; 1.6% versus 1.9% for stroke; and 1.5% versus 1.4% for CV death. Bisphosphonate treatment up to 36 months did not have any significant effects on total CV events (14 trials; ORs [95% CI]: 0.98 [0.84–1.14]; I2 = 0.0%), atrial fibrillation (41 trials; 1.08 [0.92–1.25]; I2 = 0.0%), MI (10 trials; 0.96 [0.69–1.34]; I2 = 0.0%), stroke (10 trials; 0.99 [0.82–1.19]; I2 = 5.8%), and CV death (14 trials; 0.88 [0.72–1.07]; I2 = 0.0%) with little between-study heterogeneity. The risk of atrial fibrillation appears to be modestly elevated for zoledronic acid (6 trials; 1.24 [0.96–1.61]; I2 = 0.0%), not for oral bisphosphonates (26 trials; 1.02 [0.83–1.24]; I2 = 0.0%). The CV effects did not vary by subgroups or study quality. Conclusions Bisphosphonates do not have beneficial or harmful effects on atherosclerotic CV events, but zoledronic acid may modestly increase the risk of atrial fibrillation. Given the large

    Atrial fibrillation (AF) patients are at high risk for thrombotic and vascular events related to their cardiac arrhythmia and underlying systemic atherosclerosis. Ankle-Brachial Index (ABI) is a non-invasive tool in evaluating systemic atherosclerosis, useful in predicting cardiovascular events in general population; no data are available in AF patients. ARAPACIS is a prospective multicentre observational study performed by the Italian Society of Internal Medicine, analysing association between low ABI (≤ 0.90) and vascular events in NVAF out- or in-patients, enrolled in 136 Italian centres. A total of 2,027 non-valvular AF (NVAF) patients aged > 18 years from both sexes followed for a median time of 34.7 (interquartile range: 22.0-36.0) months, yielding a total of 4,614 patient-years of observation. Mean age was 73 ± 10 years old with 55 % male patients. A total of 176 patients (8.7 %) experienced a vascular event, with a cumulative incidence of 3.81 %/patient-year. ABI≤ 0.90 was more prevalent in patients with a vascular event compared with patients free of vascular events (32.2 vs 20.2 %, p< 0.05). On Cox proportional hazard analysis, ABI≤ 0.90 was an independent predictor of vascular events (hazard ratio (HR): 1.394, 95 % confidence interval (CI): 1.042-1.866; p=0.02), vascular death (HR: 2.047, 95 % CI: 1.255-3.338; p=0.004) and MI (HR: 2.709, 95 % CI: 1.485-5.083; p=0.001). This latter association was also confirmed after excluding patients with previous MI (HR: 2.901, 95 % CI: 1.408-5.990, p=0.004). No association was observed between low ABI and stroke/transient ischaemic attack (p=0.91). In conclusion, low ABI is useful to predict MI and vascular death in NVAF patients and may independently facilitate cardiovascular risk assessment in NVAF patients.

    Background Myocarditis is a relatively common inflammatory disease that affects the myocardium. Infectious disease accounts for most of the cases either because of a direct viral infection or post-viral immune-mediated reaction. Cardiovascular magnetic resonance (CMR) has become an established non-invasive diagnosis tool for acute myocarditis. A recent large single centre study with patients with biopsy-proven viral myocarditis undergoing CMR scans found a high rate of mortality. The aim of this study was to assess the rate of clinical events in our population of patients with diagnosed myocarditis by CMR scan. Methods Patients who consulted to the emergency department with diagnosis of myocarditis by CMR were retrospectively included in the study from January 2008 to May 2012. A CMR protocol was used in all patients, and were followed up to assess the rate of the composite endpoint of all-cause death, congestive heart failure, sudden cardiac death, hospitalization for cardiac cause, recurrent myocarditis or need of radiofrequency ablation or implantable cardiac defibrillator (ICD). A descriptive statistical analysis was performed. Results Thirty-two patients with myocarditis were included in the study. The mean age was 42.6±21.2 years and 81.2% were male. In a mean follow up of 30.4±17.8 months, the rate of the composite endpoint of all-cause death, congestive heart failure, sudden cardiac death, hospitalization for cardiac cause, recurrent myocarditis or need of radiofrequency ablation or ICD was 15.6% (n=5). Two patients had heart failure (one of them underwent heart transplant), one patient needed ICD because of ventricular tachycardia and two other patients were re-hospitalized, for recurrent chest pain and for recurrent myocarditis respectively. Conclusions In our series of acute myocarditis diagnosed by CMR we found a low rate of cardiovascular events without mortality. These findings might oppose data from recently published myocarditis trials. PMID

    Objective Emerging evidence suggests that women with menopausal vasomotor symptoms (VMS) have increased cardiovascular disease (CVD) risk as measured by surrogate markers. We investigated the relationships between VMS and clinical CVD events and all-cause mortality in the Women's Health Initiative Observational Study (WHI-OS). Methods We compared the risk of incident CVD events and all-cause mortality between four groups of women (total N=60,027): (1) No VMS at menopause onset and no VMS at WHI-OS enrollment (no VMS [referent group]); (2) VMS at menopause onset, but not at WHI-OS enrollment (early VMS); (3) VMS at both menopause onset and WHI-OS enrollment (persistent VMS [early and late]); and (4) VMS at WHI-OS enrollment, but not at menopause onset (late VMS). Results For women with early VMS (N=24,753), compared to no VMS (N=18,799), hazard ratios (HRs) and 95% confidence intervals (CIs) in fully-adjusted models were: major CHD, 0.94 (0.84, 1.06); stroke, 0.83 (0.72, 0.96); total CVD, 0.89 (0.81, 0.97); and all-cause mortality, 0.92 (0.85, 0.99). For women with persistent VMS (N=15,084), there was no significant association with clinical events. For women with late VMS (N=1,391) compared to no VMS, HRs and 95% CIs were: major CHD, 1.32 (1.01, 1.71); stroke, 1.14 (0.82, 1.59); total CVD, 1.23 (1.00, 1.52); and all-cause mortality, 1.29 (1.08, 1.54). Conclusions Early VMS were not associated with increased CVD risk. Rather, early VMS were associated with decreased risk of stroke, total CVD events, and all-cause mortality. Late VMS were associated with increased CHD risk and all-cause mortality. The predictive value of VMS for clinical CVD events may vary with onset of VMS at different stages of menopause. Further research examining the mechanisms underlying these associations is needed. Future studies will also be necessary to investigate whether VMS that develop for the first time in the later postmenopausal years represent a pathophysiologic process distinct

    Objective The aim of this study was to determine if there are racial disparities in regard to the age at which SLE patients experience CVD and CVD associated death. Methods Using the 2003–2006 National Inpatient Sample, we calculated the age difference between SLE patients and their race and gender-matched controls at the time of hospitalization for a cardiovascular (CVD) event and for CVD-associated death. In addition, we also calculated the age difference for the same outcomes between White SLE patients and gender-matched controls for each minority group. Results The mean age difference at the time of CVD event between women with and without SLE was 10.5 years. All age differences between women with SLE (n=3,625) and women without SLE admitted for CVD were significant (p<0.0001). Black women were the youngest female SLE racial group to be admitted with CVD (53.9 years) and have a CVD associated inhospital mortality (52.8 years; n=218). Black SLE women were 19.8 years younger than race and gender-matched controls at the time of CVD associated death. Admission trends for CVD were reversed for Black women such that the highest proportions of these patients were admitted before age 55 and then steadily decreased across age categories. There were 805 men with SLE admitted with a CVD event, with Black and Hispanic groups being the youngest. Conclusions There are significant racial disparities with regard to age at the time of hospital admission for CVD events and a CVD-related hospitalization resulting in death in patients with SLE.

    Risk prediction equations from the Framingham Heart Study are commonly used to predict the absolute risk of myocardial infarction (MI) and coronary heart disease (CHD) related death. Predicting CHD-related events in the U.S. astronaut corps presents a monumental challenge, both because astronauts tend to live healthier lifestyles and because of the unique cardiovascular stressors associated with being trained for and participating in space flight. Traditional risk factors may not hold enough predictive power to provide a useful indicator of CHD risk in this unique population. It is important to be able to identify individuals who are at higher risk for CHD-related events so that appropriate preventive care can be provided. This is of special importance when planning long duration missions since the ability to provide advanced cardiac care and perform medical evacuation is limited. The medical regimen of the astronauts follows a strict set of clinical practice guidelines in an effort to ensure the best care. The purpose of this study was to evaluate the utility of the Framingham risk score (FRS), low-density lipoprotein (LDL) and high-density lipoprotein levels, blood pressure, and resting pulse as predictors of CHD-related death and MI in the astronaut corps, using Cox regression. Of these factors, only two, LDL and pulse at selection, were predictive of CHD events (HR(95% CI)=1.12 (1.00-1.25) and HR(95% CI)=1.70 (1.05-2.75) for every 5-unit increase in LDL and pulse, respectively). Since traditional CHD risk factors may lack the specificity to predict such outcomes in astronauts, the development of a new predictive model, using additional measures such as electron-beam computed tomography and carotid intima-media thickness ultrasound, is planned for the future.

  15. Swift: 10 Years of Discovery

    NASA Astrophysics Data System (ADS)

    The conference Swift: 10 years of discovery was held in Roma at La Sapienza University on Dec. 2-5 2014 to celebrate 10 years of Swift successes. Thanks to a large attendance and a lively program, it provided the opportunity to review recent advances of our knowledge of the high-energy transient Universe both from the observational and theoretical sides. When Swift was launched on November 20, 2004, its prime objective was to chase Gamma-Ray Bursts and deepen our knowledge of these cosmic explosions. And so it did, unveiling the secrets of long and short GRBs. However, its multi-wavelength instrumentation and fast scheduling capabilities made it the most versatile mission ever flown. Besides GRBs, Swift has observed, and contributed to our understanding of, an impressive variety of targets including AGNs, supernovae, pulsars, microquasars, novae, variable stars, comets, and much more. Swift is continuously discovering rare and surprising events distributed over a wide range of redshifts, out to the most distant transient objects in the Universe. Such a trove of discoveries has been addressed during the conference with sessions dedicated to each class of events. Indeed, the conference in Rome was a spectacular celebration of the Swift 10th anniversary. It included sessions on all types of transient and steady sources. Top scientists from around the world gave invited and contributed talks. There was a large poster session, sumptuous lunches, news interviews and a glorious banquet with officials attending from INAF and ASI. All the presentations, as well as several conference pictures, can be found in the conference website (http://www.brera.inaf.it/Swift10/Welcome.html). These proceedings have been collected owing to the efforts of Paolo D’Avanzo who has followed each paper from submission to final acceptance. Our warmest thanks to Paolo for all his work. The Conference has been made possible by the support from La Sapienza University as well as from the ARAP

    Purpose Although cardiac involvement is an infrequently recognized manifestation of venomous snakebites, little is known of the adverse cardiovascular events (ACVEs) arising as a result of snakebite in Korea. Accordingly, we studied the prevalence of ACVEs associated with venomous snakebites in Korea and compared the clinical features of patients with and without ACVEs. Materials and Methods A retrospective review was conducted on 65 consecutive venomous snakebite cases diagnosed and treated at the emergency department of Wonju Severance Christian Hospital between May 2011 and October 2014. ACVEs were defined as the occurrence of at least one of the following: 1) myocardial injury, 2) shock, 3) ventricular dysrhythmia, or 4) cardiac arrest. Results Nine (13.8%) of the 65 patients had ACVEs; myocardial injury (9 patients, 13.8%) included high sensitivity troponin I (hs-TnI) elevation (7 patients, 10.8%) or electrocardiogram (ECG) determined ischemic change (2 patients, 3.1%), and shock (2 patient, 3.1%). Neither ventricular dysrhythmia nor cardiac arrest was observed. The median of elevated hs-TnI levels observed in the present study were 0.063 ng/mL (maximum: 3.000 ng/mL) and there was no mortality in the ACVEs group. Underlying cardiac diseases were more common in the ACVEs group than in the non-ACVEs group (p=0.017). Regarding complications during hospitalization, 3 patients (5.4%) in the non-ACVEs group and 3 patients (33.3%) in the ACVEs group developed bleeding (p=0.031). Conclusion Significant proportion of the patients with venomous snakebite is associated with occurrence of ACVEs. Patients with ACVEs had more underlying cardiac disease and bleeding complication.

    To assess the prognostic value of aortic valve and mitral valve/annulus calcifications for cardiovascular events in heavily smoking men without a history of cardiovascular disease. Heavily smoking men without a cardiovascular disease history who underwent non-contrast-enhanced low-radiation-dose chest CT for lung cancer screening were included. Non-imaging predictors (age, smoking status and pack-years) were collected and imaging-predictors (calcium volume of the coronary arteries, aorta, aortic valve and mitral valve/annulus) were obtained. The outcome was the occurrence of cardiovascular events. Multivariable Cox proportional-hazards regression was used to calculate hazard-ratios (HRs) with 95% confidence interval (CI). Subsequently, concordance-statistics were calculated. In total 3111 individuals were included, of whom 186 (6.0%) developed a cardiovascular event during a follow-up of 2.9 (Q1-Q3, 2.7-3.3) years. If aortic (n = 657) or mitral (n = 85) annulus/valve calcifications were present, cardiovascular event incidence increased to 9.0% (n = 59) or 12.9% (n = 11), respectively. HRs of aortic and mitral valve/annulus calcium volume for cardiovascular events were 1.46 (95% CI, 1.09-1.84) and 2.74 (95% CI, 0.92-4.56) per 500 mm(3). The c-statistic of a basic model including age, pack-years, current smoking status, coronary and aorta calcium volume was 0.68 (95% CI, 0.63-0.72), which did not change after adding heart valve calcium volume. Aortic valve calcifications are predictors of future cardiovascular events. However, there was no added prognostic value beyond age, number of pack-years, current smoking status, coronary and aorta calcium volume for short term cardiovascular events. PMID:25962863

    OBJECTIVE: To examine the incidence of cardiovascular diseases and cancer from published clinical trials that studied other outcomes of postmenopausal hormone therapy as some surveys have suggested that it may decrease the incidence of cardiovascular diseases and increase the incidence of hormone dependent cancers. DESIGN: Trials that compared hormone therapy with placebo, no therapy, or vitamins and minerals in comparable groups of postmenopausal women and reported cardiovascular or cancer outcomes were searched from the literature. SUBJECTS: 22 trials with 4124 women were identified. In each group, the numbers of women with cardiovascular and cancer events were summed and divided by the numbers of women originally allocated to the groups. RESULTS: Data on cardiovascular events and cancer were usually given incidentally, either as a reason for dropping out of a study or in a list of adverse effects. The calculated odds ratios for women taking hormones versus those not taking hormones was 1.39 (95% confidence interval 0.48 to 3.95) for cardiovascular events without pulmonary embolus and deep vein thrombosis and 1.64 (0.55 to 4.18) with them. It is unlikely that such results would have occurred if the true odds ratio were 0.7 or less. For cancers, the numbers of reported events were too low for a useful conclusion. CONCLUSIONS: The results of these pooled data do not support the notion that postmenopausal hormone therapy prevents cardiovascular events. PMID:9251544

    Introduction Approximately 55% of women in Europe die from cardiovascular events, mostly as a result of coronary diseases and cerebral stroke. There is a 10-year shift in the cardiovascular risk between women and men. The risk in a 55-year-old female patient is similar to that of a 45-year-old man, thus the risk among women increases rapidly around the age of 50, when menopause prevails to occur. The purpose of the study was to assess and compare the SCORE-predicted risk of a fatal cardiovascular incident in pre- and postmenopausal women. Material and methods The cross-sectional study was conducted as part of community nursing practice. It covered 219 women – inhabitants of Krakow, aged from 30 to 65, without clinically validated cardiovascular diseases of arteriosclerotic and/or diabetic origin, who volunteered to take part in the study. The group was divided into three subgroups: K1 – menstruating women (n = 113), K2a – women after natural menopause (n = 88), and K2b – women after surgical menopause (n = 18). The study made use of a lifestyle questionnaire, which concerned the social and economic status, and lifestyle habits including tobacco smoking. Arterial blood pressure was measured, and total cholesterol concentration in blood (mmol/l) was recorded. Results A high (≥ 5%) level of the SCORE risk was discovered in 14.3% of postmenopausal women, as compared to 0.9% in the group of menstruating women. An average risk of a fatal cardiovascular incident during the following 10 years was significantly higher among women from groups K2a (2.61%) and K2b (2.32%) as compared to K1 – menstruating women (0.38%). No difference was, however, discovered between groups of naturally (K2a) and surgically menopausal women (K2b). Conclusions A significantly higher risk of SCORE-predicted death caused by a cardiovascular incident, as compared to the group of women in the premenopausal period, is characteristic of women in the postmenopausal period.

    Background To evaluate the predictive value of carotid atherosclerotic disease (CAD) and intima-media thickness (IMT) on incident cardiovascular disease and mortality in hemodialysis patients. Methods Multicenter, observational, prospective study including 110 patients, followed-up to 6 years. Carotid doppler ultrasonographic findings were classified in 4 degrees of severity: 1) IMT <0.9 mm, 2) IMT >0.9 mm, 3) carotid plaque with stenosis <50% and 4) plaque with stenosis >50%. The associations between IMT and CAD and cardiovascular events, total and cardiovascular mortality were assessed. Results 83% of the patients had atherosclerotic plaques (CAD degrees 3-4). During follow-up, 29.1% of patients experienced cardiovascular events, and 28.2% died, 38.7% of cardiovascular origin. The presence of plaques was associated with cardiovascular events (p = 0.03) while calcified plaques were associated with both cardiovascular events (p = 0.01), cardiovascular mortality (p = 0.03) and non-significantly with overall mortality (p = 0.08) in the survival analysis. Carotid IMT was not associated with outcomes. Cardiovascular events correlated with CAD severity (HR 2.27, 95% CI 1.13-4.54), age (HR 1.04, 1.01-1.06), previous cardiovascular disease (HR 1.75, 1.05-4.42), dyslipidemia (HR 2.25, 1.11-4.53), lipoprotein (a) (HR 1.01, 1.00-1.02), troponin I (HR 3.89, 1.07-14.18), fibrinogen levels (HR 1.38, 0.98-1.94) and antiplatelet therapy (HR 2.14, 1.04-4.4). In an age-adjusted multivariate model, cardiovascular events were independently associated with previous coronary artery disease (HR 3.29, 1.52-7.15) and lipoprotein (a) (HR 1.01, 1.00-1.02). Conclusions The presence of carotid plaques and, especially, calcified plaques, are predictors of new cardiovascular events and cardiovascular mortality in hemodialysis patients, while IMT was not. The prognostic value of calcified plaques should be confirmed in future studies. PMID:26029907

    2012-01-01

    Background Hypertriglyceridemia may be associated with important complications. The aim of this study is to estimate the magnitude of association and quality of supporting evidence linking hypertriglyceridemia to cardiovascular events and pancreatitis. Methods We conducted a systematic review of multiple electronic bibliographic databases and subsequent meta-analysis using a random effects model. Studies eligible for this review followed patients longitudinally and evaluated quantitatively the association of fasting hypertriglyceridemia with the outcomes of interest. Reviewers working independently and in duplicate reviewed studies and extracted data. Results 35 studies provided data sufficient for meta-analysis. The quality of these observational studies was moderate to low with fair level of multivariable adjustments and adequate exposure and outcome ascertainment. Fasting hypertriglyceridemia was significantly associated with cardiovascular death (odds ratios (OR) 1.80; 95% confidence interval (CI) 1.31-2.49), cardiovascular events (OR, 1.37; 95% CI, 1.23-1.53), myocardial infarction (OR, 1.31; 95% CI, 1.15-1.49), and pancreatitis (OR, 3.96; 95% CI, 1.27-12.34, in one study only). The association with all-cause mortality was not statistically significant. Conclusions The current evidence suggests that fasting hypertriglyceridemia is associated with increased risk of cardiovascular death, MI, cardiovascular events, and possibly acute pancreatitis. Précis: hypertriglyceridemia is associated with increased risk of cardiovascular death, MI, cardiovascular events, and possibly acute pancreatitis PMID:22463676

    Ambulatory blood pressure parameters, nocturnal dipping and morning surge, are associated with cardiovascular outcomes in several populations. While significant variation exists between racial groups in ambulatory blood pressure measurements and the incidence of cardiovascular disease, the effect of race on the associations of dipping and morning surge with cardiovascular outcomes is unknown. In a prospective analysis of 197 African American and 197 Japanese individuals with non-diabetic chronic kidney disease matched by age and renal function, we analyzed the associations of dipping and morning surge with cardiovascular events for both races and assessed whether these relations differed by race. Higher sleep-trough morning surge was independently associated with cardiovascular events in Japanese (hazard ratio, 1.93 per 10 mm Hg; 95% confidence interval, 1.20-3.10) but not in African American participants, with race an effect modifier (P-value <.01). Dipping was not associated with cardiovascular events in either racial group. In individuals with chronic kidney disease, the association between morning surge and cardiovascular events appears to be dependent upon race, with higher morning surge a risk factors in Japanese but not in African Americans.

    OBJECTIVE The increased cardiovascular risk in diabetes has been linked to endothelial and renal dysfunction. The aim of this study was to investigate the role of stable fragments of the precursors of adrenomedullin, endothelin-1, vasopressin, and atrial natriuretic peptide in progression of cardiovascular disease in patients with diabetes. RESEARCH DESIGN AND METHODS This was a prospective, observational study design with a composite end point (death or unexpected admission to hospital due to a cardiovascular event) on 781 patients with type 2 diabetes (54 events, median duration of observation 15 months). The four stable precursor peptides midregional adrenomedullin (MR-proADM), midregional proatrial natriuretic peptide (MR-proANP), COOH-terminal proendothelin-1 (CT-proET-1), and COOH-terminal provasopressin or copeptin (CT-proAVP) were determined at baseline, and their association to renal function and cardiovascular events was studied using stepwise linear and Cox logistic regression analysis and receiver operating characteristic analysis, respectively. RESULTS MR-proADM, CT-proET-1, CT-proAVP, and MR-proANP were all elevated in patients with future cardiovascular events and independently correlated to serum creatinine. MR-proADM and MR-proANP were significant predictors of a future cardiovascular event, with MR-proANP being the stronger (area under the curve 0.802 ± 0.034, sensitivity 0.833, specificity 0.576, positive predictive value 0.132, and negative predictive value 0.978 with a cutoff value of 75 pmol/l). CONCLUSIONS The four serum markers of vasoactive and natriuretic peptides are related to both kidney function and cardiovascular events, thus linking two major complications of diabetes, diabetic nephropathy and cardiovascular disease.

    Background and objectives Telomeric G-tails play a pivotal role in maintaining the intramolecular loop structure of telomeres. Previous in vitro studies have suggested that the erosion of telomeric G-tails triggers cellular senescence, leading to organ dysfunction and atherosclerosis. The authors recently established a method to measure telomeric G-tail length using a hybridization protection assay. Using this method, this study investigated whether telomeric G-tail length could be used as a novel predictor for future cardiovascular events in hemodialysis patients. Design, setting, participants, & measurements A prospective observational study was performed involving a cohort of 203 Japanese hemodialysis patients to examine the lengths of telomeric G-tails and total telomeres and subsequent cardiovascular events during a median follow-up period of 48 months. The lengths of telomeric G-tails and total telomeres were also measured in 203 participants who did not have CKD and who were age- and sex-matched to hemodialysis patients. Results The lengths of telomeric G-tails and total telomeres were significantly shorter in hemodialysis patients than in control subjects. Telomeric G-tails, but not total telomeres, were independently and negatively associated with clinical history of cardiovascular disease. During follow-up, 80 cardiovascular events occurred. Total telomere length did not predict cardiovascular events. However, the length of telomeric G-tails was associated with new-onset cardiovascular events (hazard ratio per log luminescence signals, 0.12; 95% confidence interval, 0.12 to 0.50) that persisted after adjustment for age, sex, diabetes mellitus, clinical history of cardiovascular disease, inflammation, use of vitamin D, and serum levels of phosphate and intact parathyroid hormone. Conclusions Longer telomeric G-tail length is associated with a lower risk of future cardiovascular events in hemodialysis patients. PMID:25237070

    Objective Coronary artery calcification (CAC) predicts cardiovascular events in the general population. We conducted a prospective study to determine if inflammatory markers were predictive of CAC and if CAC predicted cardiovascular events and mortality in incident renal transplant recipients. Methods A prospective cohort of 112 asymptomatic incident renal transplant recipients who had no prior history of coronary artery revascularization or myocardial infarction had coronary calcifications measured early post-transplant and at least 18 months later by Agatston score and volume method. Results The mean CAC score was 367.7 (682.3). Inflammatory markers such as WBC and CRP were predictive of CAC severity. Recipients with cardiovascular events (n=11) or death (n=12) during the follow-up period had higher mean [675.1 (669.3) vs. 296.8(669.0), p=0.02] and median [434.8 vs. 28.9, p=0.01] CAC score compared to those without them. Recipients with CAC score less than 100 had a better cumulative survival rate compared to the recipients with CAC score greater than 100 [95.1 vs. 82.3%, p=0.03]. We found a significant unadjusted and adjusted association between CAC score and cardiovascular events and mortality. A quarter (25.9%) of recipients had CAC progression. Coronary calcification progression also predicted cardiovascular events and mortality after adjustment for diabetes, age, dialysis vintage and presence of CAC at time of transplant. Conclusion CAC is prevalent in renal recipients and is predictive of cardiovascular events and mortality. Changes in coronary calcification are common and predict clinical outcomes. Inflammatory markers are predictive of CAC severity at time of transplant, but are not predictive of future cardiovascular event or mortality. PMID:20934074

    There are conflicting reports regarding the occurrence of cardiovascular events after a major earthquake. To understand the impact of the Great East Japan Earthquake on cardiovascular events, we retrospectively examined the clinical records prepared by emergency room physicians between 2009 and 2011 (n = 66,244), and compared the occurrence of these events between 2011 and 2009, and 2011 and 2010. There was a significant increase in the number of patients with cardiovascular events during the 3 week period after the earthquake in 2011 (n = 106) compared with that during the same period in 2009 (n = 72) or 2010 (n = 65) (P = 0.002). The number of patients with acute coronary syndrome or congestive heart failure in March 2011 was significantly increased compared with 2009 or 2010, however, there were no significant increases in 2011 in other cardiovascular events including stroke, aortic dissection, pulmonary thromboembolism, or out-of-hospital cardiac arrest compared with 2009 or 2010. These findings suggest that the incidence of cardiovascular events may have been heterogeneous after the disaster.

    Erectile dysfunction confers an independent risk for cardiovascular events and total mortality. Aortic pulse wave velocity (PWV) is an important predictor of cardiovascular events and all-cause mortality. We investigated whether PWV predicts major adverse cardiovascular events (MACEs) in patients with erectile dysfunction beyond traditional risk factors. MACEs in relation to PWV were analyzed with proportional hazards models in 344 patients (mean age, 56 years) without established cardiovascular disease. During a mean follow-up of 4.7 years (range, 1-8.5 years), 24 of 344 participants (7.0%) experienced a MACE. Subjects in the highest PWV tertile (>8.8 m/s) had a 4-fold higher risk of MACEs compared with those in the lowest PWV tertile (<7.6 m/s; adjusted hazard ratio, 3.97; P=0.035). A PWV value of 7.81 m/s was associated with a negative predictive value (ability to rule out MACE) of 98.1%. Addition of PWV to standard risk factor model yielded correct patient reclassification to higher or lower risk category by 27.6% (P=0.0332) in the whole cohort. Our results show that higher aortic stiffness is associated with increased risk for a MACE in patients with erectile dysfunction without known cardiovascular disease. Aortic PWV improves risk prediction when added to standard risk factors and may represent a valuable biomarker of prediction of cardiovascular disease risk in these patients.

    OBJECTIVE While several studies have demonstrated a high prevalence of metabolically benign obesity, little is known about the incidence of cardiovascular disease (CVD) in this group. RESEARCH DESIGN AND METHODS Using pooled data from the Atherosclerosis Risk in Communities and Cardiovascular Health Studies, we assessed the association of metabolically benign obesity with incident CVD (coronary heart disease and stroke) using three existing definitions of metabolically benign obesity: (1) the ATP-III metabolic syndrome definition (≤2 of the ATP-III components, excluding waist), (2) the expanded ATP-III definition (≤1 of: the ATP-III components, HOMA-IR>75th percentile, systemic inflammation [WBC>75th percentile]), and (3) the insulin resistance (IR) based definition (sex-specific lowest quartile of the HOMA-IR distribution among non-diabetic obese). RESULTS The sample included 4,323 normal weight and 6,121 obese individuals. Among obese, 27.0%, 18.1%, and 20.4% were metabolically benign by the three definitions, respectively. CVD incidence among metabolically benign obese defined by the three definitions (mean follow-up 11.8 years) was 8.7%, 7.2%, and 10.3%, respectively, versus 7.9% in low-risk normal weight individuals. Multivariate-adjusted hazard ratios (95% CI) of incident CVD in metabolically benign obese compared to low-risk normal weight individuals were 1.24 (0.99-1.57), 1.16 (0.86-1.56), and 1.28 (1.01-1.62), respectively. CONCLUSIONS Regardless of the definition used, we observed a high prevalence of metabolically benign obesity. All three commonly used definitions were similar in terms of both classification and subsequent risk of CVD, with the expanded ATP-III criteria perhaps identifying the obese group at lowest risk of CVD.

  10. Sporting events affect spectators' cardiovascular mortality: it is not just a game.

    Physiologic and clinical triggers, including mental stress, anxiety, and anger, often precipitate acute myocardial infarction and cardiovascular death. Sporting events can acutely increase cardiovascular event and death rates. A greater impact is observed in patients with known coronary artery disease and when stressful features are present, including a passionate fan, a high-stakes game, a high-intensity game, a loss, and a loss played at home. Sporting events affect cardiovascular health through neuroendocrine responses and possibly an increase in high-risk behaviors. Acute mental stress increases the activity of the hypothalamic-pituitary-adrenocortical axis and the sympathetic-adrenal-medullary system while impairing vagal tone and endothelial function. Collectively, these mechanisms increase myocardial oxygen demand and decrease myocardial oxygen supply while also increasing the risk of arrhythmias and thrombosis. Measures can be taken to reduce cardiovascular risk, including the use of beta-blockers and aspirin, stress management, transcendental meditation, and avoidance of high-risk activities, such as smoking, eating fatty foods, overeating, and abusing alcohol and illicit drugs. Sporting events have the potential to adversely affect spectators' cardiovascular health, and protective measures should be considered.

    Low circulating high-molecular-weight (HMW) adiponectin might be associated with increased cardiovascular risk. This study aimed to investigate the relationship between HMW adiponectin and cardiovascular events in patients with type 2 diabetes mellitus (T2DM) with an adverse cardiovascular risk profile. The investigation took place in a specialized outpatient clinic for metabolic diseases and included 147 patients with T2DM following a cross-sectional and a prospective study protocol. Ninety patients had macrovascular disease at baseline defined as preexisting coronary artery disease, previous stroke, or peripheral artery disease. HMW adiponectin measured by enzyme-linked immunosorbent assay (Fujirebio, Tokyo, Japan) and routine clinical parameters were determined in all patients at baseline. The occurrence of new cardiovascular events (myocardial infarction, stroke, and all-cause mortality) during the follow-up period was evaluated. No significant correlations between traditional cardiovascular risk markers and HMW adiponectin could be detected. HMW adiponectin did not differ between subjects with and without macrovascular disease at baseline (3.5 [interquartile range [IQR]: 2.2-5.7] mg/L vs 4.0 [IQR: 2.5-7.1] mg/L). During a follow-up of 19.3 (IQR: 16-25) months, 61 endpoints (41 myocardial infarctions, 10 strokes, and 10 deaths) were observed. A 1-standard-deviation increment of log-transformed HMW adiponectin was not significantly associated with the occurrence of cardiovascular events (Adjusted hazard ratio [HR]: 0.95; 95% confidence interval [CI]: 0.58-1.54; P = 0.835). In conclusion, HMW adiponectin was not related to present macrovascular disease and is not associated with future cardiovascular events in high-risk patients with T2DM. It is unlikely that HMW adiponectin has significant vasoprotective effects in these patients.

    Several morphological parameters based on the central aortic pressure waveform are proposed as cardiovascular risk markers, yet no study has definitively demonstrated the incremental value of any waveform parameter in addition to currently accepted biomarkers in elderly, hypertensive patients. The reservoir-wave concept combines elements of wave transmission and Windkessel models of arterial pressure generation, defining an excess pressure superimposed on a background reservoir pressure. The utility of pressure rate constants derived from reservoir-wave analysis in prediction of cardiovascular events is unknown. Carotid blood pressure waveforms were measured prerandomization in a subset of 838 patients in the Second Australian National Blood Pressure Study. Reservoir-wave analysis was performed and indices of arterial function, including the systolic and diastolic rate constants, were derived. Survival analysis was performed to determine the association between reservoir-wave parameters and cardiovascular events. The incremental utility of reservoir-wave parameters in addition to the Framingham Risk Score was assessed. Baseline values of the systolic rate constant were independently predictive of clinical outcome (hazard ratio, 0.33; 95% confidence interval, 0.13–0.82; P=0.016 for fatal and nonfatal stroke and myocardial infarction and hazard ratio, 0.38; 95% confidence interval, 0.20–0.74; P=0.004 for the composite end point, including all cardiovascular events). Addition of this parameter to the Framingham Risk Score was associated with an improvement in predictive accuracy for cardiovascular events as assessed by the integrated discrimination improvement and net reclassification improvement indices. This analysis demonstrates that baseline values of the systolic rate constant predict clinical outcomes in elderly patients with hypertension and incrementally improve prognostication of cardiovascular events.

    Several studies have indicated that approximately 25 % of patients treated with aspirin exhibit high on-treatment platelet reactivity (HTPR), which is potentially associated with cardiovascular events (CVEs). However, this association is still controversial, since the mechanisms by which HTPR contributes to CVEs remain unclear and a no standardised definition of HTPR has been established. To determine whether HTPR is associated with CVE recurrence and what type of assay would best predict CVE recurrence, we conducted a multicentre prospective cohort study of 592 stable cardiovascular outpatients treated with aspirin monotherapy for secondary prevention. Their HTPR was determined by arachidonic acid- or collagen-induced aggregation assays using two different agonist concentrations. Residual cyclooxygenase (COX)-1 activity was assessed by measuring serum thromboxane (TX)B2 or urinary 11-dehydro TXB2. Shear-induced platelet thrombus formation was also examined. We followed all patients for two years to evaluate how these seven indexes were related to the recurrence of CVEs (cerebral infarction, transient ischaemic attack, myocardial infarction, unstable angina, revascularisation, other arterial thrombosis, or cardiovascular death). Of 583 patients eligible for the analysis, CVEs occurred in 69 (11.8 %). A Cox regression model identified several classical risk factors associated with CVEs. However, neither HTPR nor high residual COX-1 activity was significantly associated with CVEs, even by applying cut-off values suggested in previous reports or a receiver-operating characteristic analysis. In conclusion, recurrence of CVEs occurred independently of HTPR and residual COX-1 activity. Thus, our findings do not support the use of platelet or COX-1 functional testing for predicting clinical outcomes in stable cardiovascular patients. PMID:27098431

    One in 5 pregnant women is obese but the impact on later health is unknown. We aimed to determine whether maternal obesity during pregnancy associates with increased premature mortality and later life major cardiovascular events. Maternity records of women who gave birth to their first child between 1950 and 1976 (n=18 873) from the Aberdeen Maternity and Neonatal databank were linked to the National Register of Deaths, Scotland and Scottish Morbidity Record. The effect of maternal obesity at first antenatal visit on death and hospital admissions for cardiovascular events was tested using time-to-event analysis with Cox proportional hazard regression to compare outcomes of mothers in underweight, overweight, or obese body mass index (BMI) categories compared with normal BMI. Median follow-up was at 73 years. All-cause mortality was increased in women who were obese during pregnancy (BMI>30 kg/m(2)) versus normal BMI after adjustment for socioeconomic status, smoking, gestation at BMI measurement, preeclampsia, and low birth weight (hazard ratio, 1.35; 95% confidence interval, 1.02-1.77). In adjusted models, overweight and obese mothers had increased risk of hospital admission for a cardiovascular event (1.16; 1.06-1.27 and 1.26; 1.01-1.57) compared with normal BMI mothers. Adjustment for parity largely unchanged the hazard ratios (mortality: 1.43, 1.09-1.88; cardiovascular events overweight: 1.17, 1.07-1.29; and obese: 1.30, 1.04-1.62). In conclusion, maternal obesity is associated with increased risk of premature death and cardiovascular disease. Pregnancy and early postpartum could represent an opportunity for interventions to identify obesity and reduce its adverse consequences.

  20. Systemic Hemodynamic Atherothrombotic Syndrome and Resonance Hypothesis of Blood Pressure Variability: Triggering Cardiovascular Events.

    2016-07-01

    Blood pressure (BP) exhibits different variabilities and surges with different time phases, from the shortest beat-by-beat to longest yearly changes. We hypothesized that the synergistic resonance of these BP variabilites generates an extraordinarily large dynamic surge in BP and triggers cardiovascular events (the resonance hypothesis). The power of pulses is transmitted to the peripheral sites without attenuation by the large arteries, in individuals with stiffened arteries. Thus, the effect of a BP surge on cardiovascular risk would be especially exaggerated in high-risk patients with vascular disease. Based on this concept, our group recently proposed a new theory of systemic hemodynamic atherothromboltic syndrome (SHATS), a vicious cycle of hemodynamic stress and vascular disease that advances organ damage and triggers cardiovascular disease. Clinical phenotypes of SHATS are large-artery atherothombotic diseases such as stroke, coronary artery disease, and aortic and pheripheral artery disease; small-artery diseases, and microcirculation-related disease such as vascular cognitive dysfunction, heart failure, and chronic kidney disease. The careful consideration of BP variability and vascular diseases such as SHATS, and the early detection and management of SHATS, will achieve more effective individualized cardiovascular protection. In the near future, information and communication technology-based 'anticipation medicine' predicted by the changes of individual BP values could be a promising approach to achieving zero cardiovascular events.

    Dietary intervention is an important approach in the prevention of cardiovascular disease. Over the last decade, some studies have suggested that a calcium-rich diet could help to control body weight, with anti-obesity effects. The potential mechanism underlying the impact of calcium on body fat has been investigated, but it is not fully understood. Recent evidence has also suggested that a calcium-rich diet could have beneficial effects on other cardiovascular risk factors, such as insulin resistance, dyslipidemia, hypertension and inflammatory states. In a series of studies, it was observed that a high intake of milk and/or dairy products (the main sources of dietary calcium) is associated with a reduction in the relative risk of cardiovascular disease. However, a few studies suggest that supplemental calcium (mainly calcium carbonate or citrate) may be associated with an increased risk of cardiovascular events. This review will discuss the available evidence regarding the relationship between calcium intake (dietary and supplemental) and different cardiovascular risk factors and/or events. PMID:22892932

    Background and objectives Cardiovascular disease is the leading cause of death in patients with CKD. IL-10 is considered an antiatherosclerotic cytokine. However, previous studies have failed to observe an association between IL-10 and cardiovascular disease in CKD. This study aimed to evaluate whether serum IL-10 levels were associated with the risk of cardiovascular events in CKD patients. Design, setting, participants, & measurements Four hundred three patients with stages 1–5 CKD were followed for a mean of 38 (range=2–42) months for fatal and nonfatal cardiovascular events. IL-10 and IL-6 were measured at baseline together with surrogates of endothelial function (flow-mediated dilatation) and proinflammatory markers (high-sensitivity C-reactive protein and pentraxin-3). The association between IL-10 and flow-mediated dilatation through linear regression analyses was evaluated. The association between IL-10 and the risk of cardiovascular events was assessed with Cox regression analysis. Results IL-10, IL-6, high-sensitivity C-reactive protein, and pentraxin-3 levels were higher among participants with lower eGFR. Both fatal (25 of 200 versus 6 of 203 patients) and combined fatal and nonfatal (106 of 200 versus 23 of 203 patients) cardiovascular events were more common in patients with IL-10 concentration above the median. Flow-mediated dilatation was significantly lower in patients with higher serum IL-10 levels, but IL-10 was not associated with flow-mediated dilatation in multivariate analysis. Kaplan–Meier survival curves showed that patients with IL-10 below the median value (<21.5 pg/ml) had higher cumulative survival compared with patients who had IL-10 levels above the median value (log-rank test, P<0.001). Conclusions IL-10 levels increase along with the reduction of kidney function. Higher serum IL-10 levels were associated with the risk of cardiovascular events during follow-up. We speculate that higher IL-10 levels in this context signify an

    Background. Efavirenz (EFV), an antiretroviral medication used to treat human immunodeficiency virus (HIV) infection, can increase lipid levels. Because hyperlipidemia is associated with increased risk for cardiovascular (CV) events, this study compared the risk of CV events in patients initiating EFV-containing vs EFV-free antiretroviral regimens. Methods. Antiretroviral-naive HIV-positive (HIV+) patients ages 18–64 were selected from commercial and Medicaid insurance claims databases. Patients with ≥1 claim for antiretroviral medications between January 1, 2007 and December 31, 2013 were classified into 2 cohorts: EFV-containing or EFV-free regimens. Patients were required to have 6 months of continuous enrollment before initiation, with no evidence of a CV event during this time. Patients were observed from initiation until the occurrence of a CV event, disenrollment, or study end. Cardiovascular events were identified through diagnosis or procedure codes for myocardial infarction, stroke, percutaneous coronary intervention, or coronary artery bypass graft. We calculated unadjusted incidence rates (IRs) and fit propensity-score-weighted Cox proportional hazards models. Results. There were 22 212 patients (11 978 EFV-containing and 10 234 EFV-free) identified in the commercial database and 7400 patients identified (2943 EFV-containing and 4457 EFV-free) in the Medicaid database. Cardiovascular events were rare (commercial IR = 396 per 100 000 person-years; Medicaid IR = 973 per 100 000 person-years). In propensity-score-weighted models, hazards of CV events were significantly lower for EFV-containing regimens in the commercial database (hazard ratio [HR] = 0.68; 95% confidence interval [CI], .49–.93) No significant difference was found in the Medicaid database (HR = 0.83; 95% CI, .58–1.19). Conclusions. This analysis found no evidence of increased risk of CV events among HIV+ patients initiating EFV-containing regimens. PMID:27186585

    Summary Background and objectives Both prolactin clearance and production are altered in CKD. In nonrenal populations, emerging evidence suggests that prolactin participates in the atherosclerotic process. Given the elevated cardiovascular risk of CKD, this study examined links between prolactinemia, vascular derangements, and outcomes. Design, setting, participants, & measurements This observational study was conducted in two cohorts: one with 457 nondialyzed CKD patients (mean age 52±12 years; 229 men) with measurements of flow-mediated dilation (FMD) and carotid intima-media thickness and one with 173 hemodialysis patients (65±12 years; 111 men) with measurements of pulse wave velocity (PWV). Patients were followed for cardiovascular events (n=146, nondialyzed cohort) or death (n=79, hemodialysis cohort). Results Prolactin levels increased along with reduced kidney function. Prolactin significantly and independently contributed to explain the variance of both FMD (in nondialyzed patients) and PWV (in hemodialysis patients), but not intima-media thickness. In Cox analyses, the risk of cardiovascular events in nondialyzed patients increased by 27% (hazard ratio [HR], 1.27; 95% confidence interval [95% CI], 1.17–1.38) for each 10 ng/ml increment of prolactin. Similarly, the risk for all-cause and cardiovascular mortality in hemodialysis patients increased by 12% (HR, 1.12; 95% CI, 1.06–1.17) and 15% (HR, 1.15; 95% CI, 1.08–1.21), respectively. This was true after multivariate adjustment for confounders and after adjustment within the purported causal pathway (FMD or PWV). Conclusions Prolactin levels directly associated with endothelial dysfunction/stiffness and with increased risk of cardiovascular events and mortality in two independent cohorts of CKD patients.

    DEVOTE was designed to evaluate the cardiovascular safety of insulin degludec (IDeg) vs insulin glargine U100 (IGlar) in patients with T2D at high risk of cardiovascular events. DEVOTE is a phase 3b, multicenter, international, randomized, double-blind, active comparator-controlled trial, designed as an event-driven trial that would continue until 633 positively adjudicated primary events were accrued. The primary end point was the time from randomization to a composite outcome consisting of the first occurrence of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke. Patients with T2D at high risk of cardiovascular complications were randomized 1:1 to receive either IDeg or IGlar, each added to background therapies. This trial was designed to demonstrate statistical noninferiority of IDeg vs IGlar for the primary end point. DEVOTE enrolled 7,637 patients between October 2013 and November 2014 at 436 sites in 20 countries. Of these, 6,506 patients had prior cardiovascular disease or chronic kidney disease, and the remainder had multiple cardiovascular risk factors. DEVOTE was designed to provide conclusive evidence regarding the cardiovascular safety of IDeg relative to IGlar in a high-risk population of patients with T2D. PMID:27595693

The purpose of this study was to compare the hypothetical potential of lifestyle modifications with that of antihypertensive medications in reducing CVD in an aging society using a success rate-oriented simulation. Methods We constructed a simulation model for virtual Japanese subpopulations according to sex and age at 10-year intervals from 40 years of age as an example of an aging society. The fractional incidence rate of CVD was calculated as the product of the incidence rate at each systolic blood pressure (SBP) level and the proportion of the SBP frequency distribution in the fractional subpopulations of each SBP. The total incidence rate was calculated by the definite integral of the fractional incidence rate at each SBP level in the sex- and age-specific subpopulations. Results If we consider the effects of lifestyle modifications on metabolic factors and transfer them onto SBP, the reductions in the total incidence rate of CVD were competitive between lifestyle modifications and antihypertensive medications in realistic scenarios. In middle-aged women, the preventive effects of both approaches were limited due to a low incidence rate. In middle-aged men and extremely elderly subjects whose adherence to antihypertensive medications is predicted to be low, lifestyle modifications could be an alternative choice. Conclusion The success rate-oriented simulation suggests that the effectiveness of lifestyle modifications or antihypertensive medications in preventing cardiovascular events largely depends on the baseline incidence rate and sex- and age-specific behavioral factors.

    Abstract Diabetic macular edema (DME) is the main cause of visual loss associated with diabetes but any association between DME and cardiovascular events is unclear. This study aims to describe the possible association between DME and cardiovascular events in a multicenter cross-sectional study of patients with type 2 diabetes. Two thousand eight hundred seven patients with type 2 diabetes were recruited from diabetes and nephrology clinical institutional centers participating in the DIAB 2 NEPHROGENE study focusing on diabetic complications. DME (presence/absence) and diabetic retinopathy (DR) classification were based on ophthalmological report and/or on 30° color retinal photographs. DR was defined as absent, nonproliferative (background, moderate, or severe) or proliferative. Cardiovascular events were stroke, myocardial infarction, and lower limb amputation. Details regarding associations between DME and cardiovascular events were evaluated. The study included 2807 patients with type 2 diabetes, of whom 355 (12.6%) had DME. DME was significantly and independently associated with patient age, known duration of diabetes, HbA1c, systolic blood pressure, and DR stage. Only the prior history of lower limb amputation was strongly associated with DME in univariate and multivariate analyses, whereas no association was found with regard to myocardial infarction or stroke. Moreover, both major (n = 32) and minor lower limb (n = 96) amputations were similarly associated with DME, with respective odds ratio of 3.7 (95% confidence interval [CI], 1.77–7.74; P = 0.0012) and of 4.29 (95% CI, 2.79–6.61; P < 0.001). DME is strongly and independently associated with lower limb amputation in type 2 diabetic patients. PMID:26287408

    Background Bilirubin has emerged as an important endogenous antioxidant molecule, and increasing evidence shows that bilirubin may protect against atherosclerosis. The SYNTAX score has been developed to assess the severity and complexity of coronary artery disease. The aim of this study was to evaluate whether serum bilirubin levels are associated with SYNTAX scores and whether they could be used to predict future cardiovascular events in patients undergoing coronary intervention. Methods Serum bilirubin levels and other blood parameters in patients with at least 12-h fasting states were determined. The primary endpoint was any composite cardiovascular event within 1 year, including death, nonfatal myocardial infarction, and target-vessel revascularization. Results In total, 250 consecutive patients with stable coronary artery disease (mean age 70 ± 13) who had received coronary intervention were enrolled. All study subjects were divided into two groups: group 1 was defined as high SYNTAX score (> 22), and group 2 was defined as low SYNTAX score (≤ 22). Total bilirubin levels were significantly lower in the high SYNTAX score group than in the low SYNTAX score group (0.51 ± 0.22 vs. 0.72 ± 0.29 mg/dl, p < 0.001). By multivariate analysis, serum total bilirubin levels were identified as an independent predictor for high SYNTAX score (adjusted odds ratio: 0.28, 95% confidence interval 0.04-0.42; p = 0.004). Use of the Kaplan-Meier analysis demonstrated a significant difference in 1-year cardiovascular events between high (> 0.8 mg/dl), medium (> 0.5, ≤ 0.8 mg/dl), and low (≤ 0.5 mg/dl) bilirubin levels (log-rank test p = 0.011). Conclusions Serum bilirubin level is associated with SYNTAX score and predicts future cardiovascular events in patients undergoing coronary intervention. PMID:27471354

    Rho-associated kinases play an important role in a variety of cellular functions. Although Rho-associated kinase activity has been shown to be an independent predictor for future cardiovascular events in a general population, there is no information on Rho-associated kinase activity in patients with acute coronary syndrome. We evaluated leukocyte Rho-associated kinase activity by Western blot analysis in 73 patients with acute coronary syndrome and 73 age- and gender-matched control subjects. Rho-associated kinase activity within 2 hours of acute coronary syndrome onset was higher in patients with acute coronary syndrome than in the control subjects (0.95±0.55 versus 0.69±0.31; P<0.001). Rho-associated kinase activity promptly increased from 0.95±0.55 to 1.11±0.81 after 3 hours and reached a peak of 1.21±0.76 after 1 day (P=0.03 and P=0.03, respectively) and then gradually decreased to 0.83±0.52 after 7 days, 0.78±0.42 after 14 days, and 0.72±0.30 after 6 months (P=0.22, P=0.29, and P=0.12, respectively). During a median follow-up period of 50.8 months, 31 first major cardiovascular events (death from cardiovascular causes, myocardial infarction, ischemic stroke, and coronary revascularization) occurred. After adjustment for age, sex, cardiovascular risk factors, and concomitant treatment with statins, increased Rho-associated kinase activity was associated with increasing risk of first major cardiovascular events (hazard ratio, 4.56; 95% confidence interval, 1.98–11.34; P<0.001). These findings suggest that Rho-associated kinase activity is dramatically changed after acute coronary syndrome and that Rho-associated kinase activity could be a useful biomarker to predict cardiovascular events in Japanese patients with acute coronary syndrome.

    Background Placental growth factor (PlGF) is a member of the vascular endothelial growth factor family that acts as a pleiotropic cytokine capable of stimulating angiogenesis and accelerating atherogenesis. Soluble fms-like tyrosine kinase-1 (sFlt-1) antagonizes PlGF action. Higher levels of PlGF and sFlt-1 have been associated with cardiovascular events in patients with chronic kidney disease, yet little is known about their relationship with adverse outcomes in patients on peritoneal dialysis (PD). The aim of this study was to investigate the association of PlGF and sFlt-1 with technique survival and cardiovascular events. Methods We measured serum levels of PlGF and plasma levels of sFlt-1 in 40 PD patients at Nara Medical University. Results PlGF and sFlt-1 levels were significantly correlated with the dialysate-to-plasma ratio of creatinine (r = 0.342, p = 0.04 and r = 0.554, p < 0.001) although PlGF and sFlt-1 levels were not correlated with total creatinine clearance and total Kt/V. Additionally, both PlGF and sFlt-1 levels were significantly higher in patients with high transport membranes compared to those without (p = 0.039 and p < 0.001, respectively). Patients with PlGF levels above the median had lower technique survival and higher incidence of cardiovascular events than patients with levels below the median, with hazard ratios of 11.9 and 7.7, respectively, in univariate Cox regression analysis. However, sFlt-1 levels were not associated with technique survival or cardiovascular events (p = 0.11 and p = 0.10, respectively). Conclusion Elevated PlGF and sFlt-1 are significantly associated with high transport membrane status. PlGF may be a useful predictor of technique survival and cardiovascular events in PD patients.

    Granulocyte-colony-stimulating-factor (G-CSF) induces mobilization of progenitor cells but may also exert pro-inflammatory and pro-thrombotic effects. Treatment with recombinant G-CSF after acute myocardial infarction is currently under examination and has been associated with in-stent restenosis. However, it is not known whether plasma levels of endogenous G-CSF are also associated with an increased cardiovascular risk. Therefore we included 280 patients with angiographically proven stable coronary artery disease. G-CSF was measured by specific ELISA and patients were followed for a median of 30 months for the occurrence of major adverse cardiovascular events (MACE: death, myocardial infarction, re-hospitalization). Those with cardiac events during follow-up showed significant higher G-CSF levels (32.3 pg/mL IQR 21.4–40.5 pg/mL vs. 24.6 pg/mL IQR 16.4–34.9 pg/mL; p<0.05) at baseline. Patients with G-CSF plasma levels above the median had a 2-fold increased risk for MACE (p<0.05). This was independent from established cardiovascular risk factors. In addition, G-CSF above the median was a predictor of clinical in-stent restenosis after implantation of bare-metal stents (6.6% vs. 19.4%; p<0.05) but not of drug-eluting stents (7.7% vs. 7.6%; p = 0.98). This data suggests that endogenous plasma levels of G-CSF predict cardiovascular events independently from established cardiac risk factors and are associated with increased in-stent restenosis rates after implantation of bare metal stents.

    Chronic kidney disease (CKD) has been considered a major risk factor for cardiovascular diseases. Although great advances have recently been made in the pathophysiology and treatment of cardiovascular diseases, CKD remains a major global health problem. Moreover, the occurrence rates of cardiovascular events among CKD patients increase even in cases in which patients undergo hemodialysis, and the mechanisms underlying the so-called "cardiorenal syndrome" are not clearly understood. Recently, small-molecule uremic toxins have been associated with cardiovascular mortality in CKD and/or dialysis patients. These toxins range from small uncharged solutes to large protein-bound structures. In this review, we focused on protein-bound uremic toxins, such as indoxyl sulfate and p-cresyl sulfate, which are poorly removed by current dialysis techniques. Several studies have demonstrated that protein-bound uremic toxins, especially indoxyl sulfate, induce vascular inflammation, endothelial dysfunction, and vascular calcification, which may explain the relatively poor prognosis of CKD and dialysis patients. The aim of this review is to provide novel insights into the effects of indoxyl sulfate and p-cresyl sulfate on the pathogenesis of atherosclerosis.

    Proprotein convertase subtilisin kexin 9 (PCSK9) inhibitors have emerged as a novel treatment option in patients with hypercholesterolemia. Evolocumab and alirocumab have achieved consistent and significant (around 60%) reduction in low-density lipoprotein cholesterol (LDL-C) levels when added to statin therapy in short term studies. The Open-Label Study of Long-term Evaluation Against LDL-C (OSLER), and The Long-term Safety and Tolerability of Alirocumab in High Cardiovascular Risk Patients with Hypercholesterolemia Not Adequately Controlled with Their Lipid Modifying Therapy (ODYSSEY LONG TERM) studies are two phase 3, multicentre, randomized, placebo controlled studies that were conducted to evaluate the long term efficacy and safety of evolocumab and alirocumab respectively in reducing lipids and cardiovascular (CV) events. Both studies demonstrated additional 48-53% reduction of CV events when added to statin therapy. Most adverse events occurred with similar frequency in the two groups; however the rate of neurocognitive adverse events was higher with evolocumab and alirocumab than with placebo. These data provide strong support for the notion that lower LDL-C goal is better, and may confirm the role of PCSK9 inhibitors as a new frontier in lipid management. The results of larger long-term outcome studies are still awaited.

    Background The left atrial size has been considered as a useful marker of adverse cardiovascular outcomes. However, it is not well known whether left atrial area index (LAAI) has predictive value for prognosis in patients with unstable angina pectoris (UAP). This study was aimed to assess the association between LAAI and outcomes in UAP patients. Methods We enrolled a total of 391 in-hospital patients diagnosed as UAP. Clinical and echocardiographic data at baseline were collected. The patients were followed for the development of adverse cardiovascular (CV) events, including hospital readmission for angina pectoris, acute myocardial infarction (AMI), congestive heart failure (CHF), stroke and all-cause mortality. Results During a mean follow-up time of 26.3 ± 8.6 months, 98 adverse CV events occurred (84 hospital readmission for angina pectoris, four AMI, four CHF, one stroke and five all-cause mortality). In a multivariate Cox model, LAAI [OR: 1.140, 95% CI: 1.016–1.279, P = 0.026], diastolic blood pressure (OR: 0.976, 95% CI: 0.956–0.996, P = 0.020) and pulse pressure (OR: 1.020, 95% CI: 1.007–1.034, P = 0.004) were independent predictors for adverse CV events in UAP patients. Conclusions LAAI is a predictor of adverse CV events independent of clinical and other echocardiographic parameters in UAP patients. PMID:27781054

    Vascular events are one of the major causes of death in case of Cushing's syndrome (CS). However, due to the relative low frequency of CS, it is hard to perform a risk assessment for these events. As represented congestive heart failure (C), hypertension (H), age (A), diabetes (D), and stroke (S), the CHADS2 score is now accepted to classify the risk of major adverse cardiovascular events (MACEs) in patients with atrial fibrillation. In this study, participants were enrolled from the National Health Research Institute Database (NHIRD) of Taiwan, and we reviewed 551 patients with their sequential clinically diagnosed CS data between 2002 and 2009 in relation to MACEs risk using CHADS2 score. Good correlation could be identified between the CS and CHADS2 score (AUC = 0.795). Our results show that patients with CS show significantly higher risk of vascular events and the CHADS2 score could be applied for MACEs evaluation. Adequate lifestyle modifications and aggressive cardiovascular risks treatment are suggested for CS patients with higher CHADS2 score. PMID:25101124

  1. Aspirin in the prevention of cardiovascular events in patients with diabetes.

    PubMed

    Bell, David S H

    2016-01-01

    Diabetes imparts a substantial increased risk for cardiovascular disease-related mortality and morbidity. Because of this, current medical guidelines recommend prophylactic treatment with once-daily, low-dose aspirin (acetylsalicylic acid) for primary and secondary prevention of cardiovascular (CV) events in high-risk patients. However, only modest reductions in CV events and mortality have been observed with once-daily aspirin treatment in patients with diabetes, including patients with a previous CV event, perhaps because of disparity between aspirin pharmacokinetics and diabetes-related platelet abnormalities. Once-daily aspirin irreversibly inactivates platelets for only a short duration (acetylsalicylic acid half-life, approximately 15-20 minutes), after which time newly generated, active platelets enter the circulation and weaken aspirin's effect. Platelets from patients with diabetes are more reactive and are turned over more rapidly than platelets from normal individuals; the short inhibitory window provided by once-daily aspirin may therefore be insufficient to provide 24-h protection against CV events. Alternative conventional aspirin regimens (e.g. higher daily dose, twice-daily dosing, combination with clopidogrel) and newer formulations (e.g. 24-h, extended-release) have been proposed to overcome the apparent limited efficacy of conventional aspirin in patients with diabetes; however, tolerability concerns and limited clinical efficacy data need to be taken into account when considering the use of such regimens.

    Background Triglyceride levels were found to be independently predictive of the development of primary coronary heart disease in epidemiologic studies. The objective of this study was to determine whether triglyceride levels were predictive of cardiovascular events in randomized controlled trials (RCTs) of lipid-modifying drugs. Methods We performed a systematic review and meta-regression analysis of 40 RCTs of lipid-modifying drugs with cardiovascular events as an outcome. The log of the rate ratio of cardiovascular events (eg, coronary death or myocardial infarction) was plotted against the proportional difference between treatment and control groups in triglyceride and other lipid levels (high density lipoprotein cholesterol [HDL-C], low density lipoprotein cholesterol [LDL-C], and total cholesterol) for all trials and for trials of primary and secondary prevention populations. Linear regression was used to determine the statistical significance of the relationship between lipid values and cardiovascular events. Results The proportional difference in triglyceride levels was predictive of cardiovascular events in all trials (P=0.005 for the slope of the regression line; N=40) and in primary prevention trials (P=0.010; N=11), but not in secondary prevention trials (P=0.114; N=25). The proportional difference in HDL-C was not predictive of cardiovascular events in all trials (P=0.822; N=40), or in trials of primary (P=0.223; N=11) or secondary (P=0.487; N=25) prevention. LDL-C levels were predictive of cardiovascular events in both primary (P=0.002; N=11) and secondary (P<0.001; N=25) populations. Conclusions Changes in triglyceride levels were predictive of cardiovascular events in RCTs. This relationship was significant in primary prevention populations but not in secondary prevention populations. PMID:24204156

    Objective This study assesses whether the relationship of lipoprotein(a) (Lp(a)) with cardiovascular risk may be modified by concurrent hormone therapy (HT). Background Prior studies indicate that hormone therapy (HT) decreases plasma levels of Lp(a), but few have been powered to assess whether it modifies the relationship of Lp(a) with cardiovascular disease (CVD). Methods Lp(a) at baseline was measured among 27,736 initially healthy women, of whom 12,075 indicated active HT use at the time of blood draw at study initiation, and 15,661 did not. The risk of first-ever major cardiovascular event (nonfatal myocardial infarction, nonfatal cerebrovascular event, coronary revascularization or cardiovascular deaths) over a ten-year period was assessed in Cox-proportional hazard models according to Lp(a) levels and HT status, and adjusted for potential confounding variables. Results As anticipated, Lp(a) values were lower among women taking HT (median 9.4 vs. 11.6 mg/dL, P<0.0001). In women not taking HT, the hazard ratio of future CVD for the highest Lp(a) quintile compared to the lowest was 1.8 (P-trend <0.0001), after adjusting for age, smoking, blood pressure, diabetes, body mass index, total cholesterol, HDL, C-reactive protein and treatment arms of aspirin and Vitamin E. In contrast, among women taking HT, there was little evidence of association with CVD [hazard ratio 1.1, P-trend =0.18; interaction P-value 0.0009 between Lp(a) quintiles and HT on incident CVD]. Conclusion The relationship of high Lp(a) levels with increased CVD is modified by hormone therapy. These data suggest that the predictive utility of Lp(a) is markedly attenuated among women taking HT, and may inform clinicians’ interpretation of Lp(a) values in such patients. PMID:18598891

    2015-01-01

    Background The Major Adverse Cardiovascular Events calculator (CRCRTR-MACE) estimates the burden of cardiovascular risk in renal transplant recipients (RTR). Our recent study of 95 RTR reported the 7-year median risk of cardiovascular events (CVE) to be 9.97%, ranging from 1.93 to 84.27%. Nearly a third (28.4%) of the cohort was above 20% risk for a CVE. Since interleukins (ILs) as part of the inflammatory response may play a role in the pathogenesis of cardiovascular disease (CVD), we extended this study to identify which ILs are associated with high cardiovascular risk in this population. Methods Twenty-two ILs were measured by multiplexed fluorescent bead-based immunoassay in 95 RTR and 56 normal controls. Stepwise analysis after multivariate determination of significant demographic and inflammatory variables was performed between the high and low-CVD risk groups (which were arbitrarily set at scores <10% and ≥20%, respectively). Normalized data was presented as mean ± SD and non-normalized data as median (minimum–maximum). Significance was measured at <0.05. Results 27.5% of the low-risk and 31.3% of the high-risk groups had mean IL levels above the 95 percentile of the normal control levels. In the non-parametric analysis IL-6, 9, 16, 17 and 33 were significantly higher in the high-risk group compared to the control. Univariate analysis (UVA) of the high-risk group identified IL-33 as the only IL that remained significantly higher than the control and low-risk groups (p = 0.000). The percentage of patients with IL-33 levels above the 90 percentile of control value in the low and high-risk groups were 15.6% and 52.0%, respectively (p<0.002). UVA of factors significant to high IL-33 levels included estimated glomerular filtration rate (eGFR), while diabetes mellitus, serum phosphorus, microalbuminuria and age also remained significant in the multivariate analysis. Conclusion Circulating IL-33 level is positively associated with high CRCRTR-MACE score

    Objectives This study descriptively examined acute and longer term direct medical costs associated with a major cardiovascular (CV) event among high-risk coronary heart disease risk-equivalent (CHD-RE) patients. It also gives a firsthand look at fatal versus nonfatal CV events. Methods The MarketScan® Commercial Claims and Encounters Database was used to identify adults with a CV event in 2006–2012 with hyperlipidemia or lipid-lowering therapy use in the 18 months prior to one of the following inpatient CV events: myocardial infarction, ischemic stroke, unstable angina, transient ischemic attack, percutaneous coronary intervention, or coronary artery bypass graft (CABG). Patients were required to have a preindex diagnosis of at least one of the following: peripheral arterial disease, abdominal aortic aneurysm, carotid artery disease, or diabetes. A subset analysis was conducted with patients with data linkable to the Social Security Administration Master Death File. Direct medical costs were reported for each quarter following a CV event, for up to 36 months after the first CV event. Results In total, 38,609 CHD-RE patients were included, mean age 57 years, 31% female. CABG, myocardial infarction, and percutaneous coronary intervention were the most frequent and most expensive first CV events, accounting for >75% of all first CV events with mean first quarter costs ranging from $17,454 (nonfatal transient ischemic attack) to $125,690 (fatal CABG). Overall, 15% of those with a first CV event went on to have a second event during the 36-month study period with mean first quarter nonfatal and fatal costs similar to first event levels. Third CV events were rare, happening in less than 3% of patients. Conclusion CV events among CHD-RE patients were costly regardless of sequence, averaging $47,433 in the first 90 days following an event and remaining high, never returning to preevent levels. When fatal, first CV event costs were 1.2 to 2.9 times higher than when

    The association between psoriasis and risk of major cardiovascular (CV) events (myocardial infarction, acute coronary syndrome, unstable angina, and stroke) is unclear. A cohort study with 48,523 patients with psoriasis and 208,187 controls was conducted. During a median follow-up of 5.2 years, 1,257 patients with psoriasis (2.59%) had a major CV event, compared with 4,784 controls (2.30%). In the multivariable analysis, inflammatory arthritis hazard ratio (HR) 1.36 (1.18-1.58), diabetes HR 1.18 (1.06-1.31), chronic kidney disease HR 1.18 (1.07-1.31), hypertension HR 1.37 (1.29-1.45), transient ischemic attack HR 2.74 (2.41-3.12), atrial fibrillation HR 1.54 (1.36-1.73), valvular heart disease HR 1.23 (1.05-1.44), thromboembolism 1.32 (1.17-1.49), congestive heart failure HR 1.57 (1.39-1.78), depression HR 1.16 (1.01-1.34), current smoker HR 2.18 (2.03-2.33), age (year) HR 1.07 (1.07-1.07), and male gender HR 1.83 (1.69-1.98) were statistically significant for the risk of major CV events. The age- and gender-adjusted HRs of a major CV event for psoriasis were 1.10 (1.04-1.17) and for severe psoriasis 1.40 (1.07-1.84), whereas the fully adjusted HRs were attenuated to 1.02 (0.95-1.08) and 1.28 (0.96-1.69). In conclusion, neither psoriasis nor severe psoriasis were associated with the short-to-medium term (over 3-5 years) risk of major CV events after adjusting for known cardiovascular disease risk factors.

    Although atherosclerosis starts in early life, evidence on risk factors and atherosclerosis in individuals aged <45 years is scarce. Therefore, we studied the relationship between risk factors, common carotid intima-media thickness (CIMT), and first-time cardiovascular events in adults aged <45 years. Our study population consisted of 3067 adults aged <45 years free from symptomatic cardiovascular disease at baseline, derived from 6 cohorts that are part of the USE-IMT initiative, an individual participant data meta-analysis of general-population-based cohort studies evaluating CIMT measurements. Information on risk factors, CIMT measurements, and follow-up of the combined end point (first-time myocardial infarction or stroke) was obtained. We assessed the relationship between risk factors and CIMT and the relationship between CIMT and first-time myocardial infarction or stroke using a multivariable linear mixed-effects model and a Cox proportional-hazards model, respectively. During a follow-up of 16.3 years, 55 first-time myocardial infarctions or strokes occurred. Median CIMT was 0.63 mm. Of the risk factors under study, age, sex, diastolic blood pressure, body mass index, total cholesterol, and high-density lipoprotein cholesterol related to CIMT. Furthermore, CIMT related to first-time myocardial infarction or stroke with a hazard ratio of 1.40 per SD increase in CIMT, independent of risk factors (95% confidence interval, 1.11-1.76). CIMT may be a valuable marker for cardiovascular risk in adults aged <45 years who are not yet eligible for standard cardiovascular risk screening. This is especially relevant in those with an increased, unfavorable risk factor burden. PMID:25624341

    Chronic administration of high levels of selective COX-2 inhibitors (coxibs), particularly rofecoxib, valdecoxib, and parecoxib, increases risk for cardiovascular disease. Understanding the possibly multiple mechanisms underlying these adverse cardiovascular events is critical for evaluating the risks and benefits of coxibs and for development of safer coxibs. The current understanding of these mechanisms is likely incomplete. Using a metabolomics approach, we demonstrate that oral administration of rofecoxib for 3 mo results in a greater than 120-fold higher blood level of 20-hydroxyeicosatetraenoic acid (20-HETE), which correlates with a significantly shorter tail bleeding time in a murine model. We tested the hypothesis that this dramatic increase in 20-HETE is attributable to inhibition of its metabolism and that the shortened bleeding time following rofecoxib administration is attributable, in part, to this increase. The s.c. infusion of 20-HETE shortened the tail bleeding time dramatically. Neither 20-HETE biosynthesis nor cytochrome P4A-like immune reactivity was increased by rofecoxib administration, but 20-HETE production increased in vitro with the addition of coxib. 20-HETE is significantly more potent than its COX-mediated metabolites in shortening clotting time in vitro. Furthermore, 20-HETE but not rofecoxib significantly increases rat platelet aggregation in vitro in a dose-dependent manner. These data suggest 20-HETE as a marker of rofecoxib exposure and that inhibition of 20-HETE's degradation by rofecoxib is a partial explanation for its dramatic increase, the shortened bleeding time, and, possibly, the adverse cardiovascular events associated with rofecoxib.

    BACKGROUND: Higher levels of red blood cell distribution width (RDW) may be associated with adverse outcomes in patients with heart failure. We examined the association between RDW and the risk of all-cause mortality and adverse cardiovascular outcomes in a population of people with coronary disease who were free of heart failure at baseline. METHODS AND RESULTS: We performed a post hoc analysis of data from the Cholesterol and Recurrent Events study. Baseline RDW was measured in 4111 participants who were randomized to receive pravastatin 40 mg daily or placebo and followed for a median of 59.7 months. We used Cox proportional hazards models to examine the association between RDW and adverse clinical outcomes. During nearly 60 months of follow-up, 376 participants died. A significant association was noted between baseline RDW level and the adjusted risk of all-cause mortality (hazard ratio per percent increase in RDW, 1.14; 95% confidence interval, 1.05 to 1.24). After categorization based on quartile of baseline RDW and further adjustment for hematocrit and other cardiovascular risk factors, a graded independent relation between RDW and death was observed (P for trend=0.001). For instance, participants with RDW in the highest quartile had an adjusted hazard ratio for death of 1.78 (95% confidence interval, 1.28 to 2.47) compared with those in the lowest quartile. Higher levels of RDW were also associated with increased risk of coronary death/nonfatal myocardial infarction, new symptomatic heart failure, and stroke. CONCLUSIONS: We found a graded independent relation between higher levels of RDW and the risk of death and cardiovascular events in people with prior myocardial infarction but no symptomatic heart failure at baseline.

    Introduction The aim of this study was to determine prognostic factors for the risk of new vascular events during the first 6 months after acute myocardial infarction (AMI) or atherothrombotic stroke (AS). We were interested in the prognostic role of endothelial progenitor cells (EPC) and circulating endothelial cells (CEC) Methods Between February 2009 and July 2012, 100 AMI and 50 AS patients were consecutively studied in three Spanish centres. Patients with previously documented coronary artery disease or ischemic strokes were excluded. Samples were collected within 24h of onset of symptoms. EPC and CEC were studied using flow cytometry and categorized by quartiles. Patients were followed for up to 6 months. NVE was defined as new acute coronary syndrome, transient ischemic attack (TIA), stroke, or any hospitalization or death from cardiovascular causes. The variables included in the analysis included: vascular risk factors, carotid intima-media thickness (IMT), atherosclerotic burden and basal EPC and CEC count. Multivariate survival analysis was performed using Cox regression analysis. Results During follow-up, 19 patients (12.66%) had a new vascular event (5 strokes; 3 TIAs; 4 AMI; 6 hospitalizations; 1 death). Vascular events were associated with age (P = 0.039), carotid IMT≥0.9 (P = 0.044), and EPC count (P = 0.041) in the univariate analysis. Multivariate Cox regression analysis showed an independent association with EPC in the lowest quartile (HR: 10.33, 95%CI (1.22–87.34), P = 0.032] and IMT≥0.9 [HR: 4.12, 95%CI (1.21–13.95), P = 0.023]. Conclusions Basal EPC and IMT≥0.9 can predict future vascular events in patients with AMI and AS, but CEC count does not affect cardiovascular risk. PMID:26332322

    Statins reduce cardiovascular events and cardiovascular and total mortality in persons at risk for and with coronary disease, but there remains a significant residual event rate, particularly in those with the atherogenic lipid phenotype that is characterized by a low high-density lipoprotein (HDL) cholesterol and increase in non-HDL cholesterol. Large outcome trials designed to assess the value of combining statins with other agents to target HDL cholesterol and non-HDL cholesterol will not be completed for a few years, but there is ample evidence for the clinician to consider combination therapy. The choices for therapies to supplement statins include niacin, fibrates, and omega-3 fatty acids. We present the argument that after therapeutic lifestyle changes, the first priority should be the maximally tolerated effective dose of a potent statin. Evidence supports the addition of niacin as the second agent. In some situations, high-dose omega-3 fatty acid therapy could be the first agent added to statins. Although fibrate monotherapy alone or in combination with non-statin low-density lipoprotein cholesterol-lowering agents can be effective in mixed hyperlipidemia when statins are not tolerated, the combination of statin+fibrate should be considered second-line therapy until the efficacy and safety are established.

    Atherosclerosis is considered a generalized disease. Similar or identical etiopathogenetic mechanisms and risk factors are involved in various atherosclerotic diseases, and the positive effects of preventive measures on atherogenesis in different parts of the arterial system were shown. However, until know, great emphasis has been placed on the aggressive pharmacological management of coronary artery disease (CHD), while less attention has been devoted to the management of peripheral arterial disease (PAD), despite its significant morbidity and mortality. Data on the efficacy of preventive measures in PAD patients have mostly been gained from subgroup analyses from studies devoted primarily to the management of coronary patients. These data have shown that treatment of risk factors for atherosclerosis with drugs can reduce cardiovascular events also in patients with PAD. The effects of some preventive procedures in PAD patients differ from coronary patients. Aspirin as a basic antiplatelet drug has been shown to be less effective in PAD patients than in coronary patients. The latest Antithrombotic Trialists’ Collaboration (ATC) meta-analysis demonstrates no benefit of aspirin in reducing cardiovascular events in PAD. Statins reduce cardiovascular events in all three of the most frequently presented cardiovascular diseases, including PAD to a comparable extent. Recent studies indicate that in PAD patients, in addition to a reduction in cardiovascular events, statins may have some hemodynamic effects. They prolong walking distance and improve quality of life. Similarly, angiotensin enzyme inhibitors are also effective in the prevention of cardiovascular events in coronary, cerebrovascular, as well as PAD patients and show positive effects on the walking capacity of patients with intermittent claudication. In PAD patients, the treatment of hypertension and diabetes also effectively prevents cardiovascular morbidity and mortality. As PAD patients are at a highest

    Background: Carotid ultrasound appears to be useful in the assessment of cardiovascular risk. In this study, we have assessed the carotid intima-media thickness (CIMT) in a group of individuals without a history of cardiovascular events. Methods: A sample of 431subjects (189 [43.9%] males and 242 [56.1%] females) was obtained from an urban population using a stratified-cluster method in Mashhad stroke and heart atherosclerosis disorder study. None of the subjects had a history of the cardiovascular event. Carotid artery duplex ultrasound was used to determine the CIMT in all subjects, and to identify those with an abnormal value (CIMT [+]; i.e., CIMT ≥ 0.8 mm). Dietary intake of participants was assessed using a questionnaire for 24-h dietary recall. The relationship between anthropometric, biochemical and dietary data and CIMT were assessed. Results: The mean age of subjects was 48.7 ± 8.0 years. Of the 431 patients, 118 (27.4%) were found to be CIMT (+). Of the cardiovascular parameters assessed, only age (odds ratio [OR] [95% confidence interval (CI)], 1.11 [0.56-4.34]; P < 0.01) and male gender (OR [95% CI], 1.14 [0.63-2.23]; P < 0.05) were significant independent predictors of ultrasound defined CIMT. Crude and total energy adjusted intake were not associated with the presence of CIMT (+). Conclusions: It appears that within a relatively young Iranian population of individuals without a history of cardiovascular event, the presence of CIMT (+) defined by duplex ultrasound cut-off value of ≥0.8 mm, did not associate with several modifiable cardiovascular risk factors or measures of dietary intake.

    Abstract The association between dialysis vascular access dysfunction and the risk of developing major adverse cardiovascular events (MACE) in hemodialysis patients is unclear and has not yet been investigated. We analyzed data from the National Health Insurance Research Database of Taiwan to quantify this association. Adopting a case–control design nested within a cohort of patients who received hemodialysis from 2001 to 2010, we identified 9711 incident cases of MACE during the stage of stable maintenance dialysis and 19,422 randomly selected controls matched to cases on age, gender, and duration of dialysis. Events of vascular access dysfunction in the 6-month period before the date of MACE onset (ie, index date) for cases and before index dates for controls were evaluated retrospectively. The presence of vascular access dysfunction was associated with a 1.385-fold higher odds of developing MACE as estimated from the logistic regression analysis. This represents a significantly increased adjusted odds ratio (OR) at 1.268 (95% confidence interval [CI] = 1.186–1.355) after adjustment for comorbidities and calendar years of initiating dialysis. We also noted a significant exposure–response trend (P < 0.001) between the frequency of vascular access dysfunction and MACE, with the greatest risk (adjusted OR = 1.840, 95% CI = 1.549–2.186) noted in patients with ≥3 vascular access events. We concluded that dialysis vascular access dysfunction was significantly associated with an increased risk of MACE. Hence, vascular access failure can be an early sign for MACE in patients receiving maintenance hemodialysis. Active monitoring and treatment of cardiovascular risk factors and related diseases, not merely managing vascular access dysfunction, would be required to reduce the risk of MACE. PMID:26131808

  15. Dust events as a risk factor for daily hospitalization for respiratory and cardiovascular diseases in Minqin, China

    Dust events are common air pollution events in parts of the world with arid, semi-arid, or desert areas. There is little research on the association between respiratory and cardiovascular health and dust events in places which are close to the deserts. The aim of this study is to evaluate the health effects of dust events in a location where traffic and industry are underdeveloped and dust events are most frequent in China. The setting allows the opportunity to reduce confounding by anthropogenically derived particulate matter and to confirm the health effects of dust events. The present study was done using daily counts of hospitalizations in Minqin (1994-2003) for respiratory and cardiovascular diseases (International Classification of Diseases, Tenth revision) for males and females. Using a semi-parametric generalized additive model and controlling for long-term temporal trends, day of the week, meteorological factors, and seasonal influence, counts of hospitalization were analyzed for dust events in a Poisson regression. Relative risks (RRs) were used to estimate the risk of dust events for respiratory and cardiovascular hospitalizations. In the year-round model, dust events with a lag of 3 days were significantly associated with total respiratory hospitalization for males and females, with RRs of 1.14 (95% confidence interval (CI) 1.01-1.29) and 1.18 (95% CI 1.00-1.41); dust events with a lag of 4 days were significantly associated with upper respiratory tract infection (URTI) in males (RR 1.28, 95% CI 1.04-1.59), and dust events with a lag of 6 days were significantly associated with pneumonia in males, with an RR of 1.17 (95% CI 1.00-1.38). A significant association between dust events with a lag of 3 days and hypertension in males was also found (RR 1.30, 95% CI 1.03,1.64). In the seasonal analysis model, the associations between the dust events and respiratory and cardiovascular hospitalizations were stronger in spring and in winter, respectively. The

    With the exponential growth of cardiovascular implantable electronic devices (CIEDs) in pediatric patients, a new method of long-term surveillance, remote monitoring (RM), has become the standard of care. The purpose of this study was to determine the usefulness of RM as a monitoring tool in the pediatric population. A retrospective review was performed of 198 patients at the University of Iowa Children's Hospital who had CIEDs. Data transmitted by RM were analyzed. The following data were examined: patient demographics; median interval between transmissions; detection of adverse events requiring corrective measures, including detection of lead failure; detection of arrhythmias and device malfunctions independent of symptoms; time gained in the detection of events using RM versus standard practice; the validity of RM; and the impact of RM on data management. Of 198 patients, 162 submitted 615 RM transmissions. The median time between remote transmissions was 91 days. Of 615 total transmissions, 16 % had true adverse events with 11 % prompting clinical intervention. Of those events requiring clinical response, 61 % of patients reported symptoms. The median interval between last follow-up and occurrence of events detected by RM was 46 days, representing a gain of 134 days for patients followed-up at 6-month intervals and 44 days for patients followed-up at 3 month-intervals. The sensitivity and specificity of RM were found to be 99 and 72 %, respectively. The positive and negative predictive values were found to be 41 and 99 %, respectively. RM allows for early identification of arrhythmias and device malfunctions, thus prompting earlier corrective measures and improving care and safety in pediatric patients.

    Objective We assessed gastrointestinal bleeding (GIB) and cardiovascular (CV) risks such as myocardial infarction or stroke associated with non-steroidal anti-inflammatory drug (NSAID) use among elderly patients with diabetes. Methods Using a nationwide claims database covering 2008–2012, we conducted a cohort study of patients with diabetes aged ≥65 years. Among the 117 610 patients, NSAID users and non-users were propensity score matched, excluding any who had experienced a potentially confounding event in the year prior to cohort entry. Multivariate Cox regression models treating death as competing risk were used. Results There were 2184 (1.86%) cases of GIB and NSAID users had an adjusted HR (aHR) of 1.68 (95% CI 1.54 to 1.83) of GIB risk after adjusting for age, sex, comorbidities and recent medications compared to NSAID non-users. There were 9333 (7.94%) cases of myocardial infarction or stroke with an aHR of 1.20 (95% CI 1.15 to 1.25). The risk of GIB was higher in patients with liver disease and renal failure, while that of CV events was higher in patients who received anticoagulants, antiplatelet agents, aspirin and selective serotonin reuptake inhibitors. The number needed to harm was 111 for GIB and 77 for CV events. Among different NSAIDs, nimesulide increased the risk of GIB and ketorolac increased the risk of CV events compared to celecoxib (aHR 2.60 and 3.13, respectively). Conclusions Elderly patients with diabetes treating NSAIDs had a significantly higher risk of both upper GIB and CV events compared to NSAID non-users, and the risk varied among different NSAIDs regardless of cyclooxygenase-2 activity.

    We investigated the cardiovascular thrombotic risk after surgical castration (SC) versus gonadotropin-releasing hormone agonists (GnRHa) in Chinese men with prostate cancer. All Chinese prostate cancer patients who were treated with SC or GnRHa from year 2000 to 2009 were reviewed and compared. The primary outcome was any new-onset of cardiovascular thrombotic events after SC or GnRHa, which was defined as any event of acute myocardial infarction or ischemic stroke. The risk of new-onset cardiovascular thrombotic event was compared between the SC group and the GnRHa group using Kaplan-Meier method. Multivariate Cox regression analysis was performed to adjust for other potential confounding factors. A total of 684 Chinese patients was included in our study, including 387 patients in the SC group and 297 patients in the GnRHa group. The mean age in the SC group (75.3 ± 7.5 years) was significantly higher than the GnRHa group (71.8 ± 8.3 years) (P < 0.001). There was increased risk of new cardiovascular thrombotic events in the SC group when compared to the GnRHa group upon Kaplan-Meier analysis (P = 0.014). Upon multivariate Cox regression analysis, age (hazard ratio [HR] 1.072, 95% confidence interval [CI] 1.04-1.11, P< 0.001), hyperlipidemia (HR 2.455, 95% CI 1.53-3.93, P< 0.001), and SC (HR 1.648, 95% CI 1.05-2.59, P= 0.031) were significant risk factors of cardiovascular thrombotic events. In conclusion, SC was associated with increased risk of cardiovascular thrombotic events when compared to GnRHa. This is an important aspect to consider while deciding on the method of androgen deprivation therapy, especially in elderly men with known history of hyperlipidemia.

    Background Impaired renal function causes dyslipidemia that contributes to elevated cardiovascular risk in patients with chronic kidney disease (CKD). The proprotein convertase subtilisin/kexin type 9 (PCSK9) is a regulator of the LDL receptor and plasma cholesterol concentrations. Its relationship to kidney function and cardiovascular events in patients with reduced glomerular filtration rate (GFR) has not been explored. Methods Lipid parameters including PCSK9 were measured in two independent cohorts. CARE FOR HOMe (Cardiovascular and Renal Outcome in CKD 2–4 Patients—The Forth Homburg evaluation) enrolled 443 patients with reduced GFR (between 90 and 15 ml/min/1.73 m2) referred for nephrological care that were prospectively followed for the occurrence of a composite cardiovascular endpoint. As a replication cohort, PCSK9 was quantitated in 1450 patients with GFR between 90 and 15 ml/min/1.73 m2 enrolled in the Ludwigshafen Risk and Cardiovascular Health Study (LURIC) that were prospectively followed for cardiovascular deaths. Results PCSK9 concentrations did not correlate with baseline GFR (CARE FOR HOMe: r = -0.034; p = 0.479; LURIC: r = -0.017; p = 0.512). 91 patients in CARE FOR HOMe and 335 patients in LURIC reached an endpoint during a median follow-up of 3.0 [1.8–4.1] years and 10.0 [7.3–10.6] years, respectively. Kaplan-Meier analyses showed that PCSK9 concentrations did not predict cardiovascular events in either cohort [CARE FOR HOMe (p = 0.622); LURIC (p = 0.729)]. Sensitivity analyses according to statin intake yielded similar results. Conclusion In two well characterized independent cohort studies, PCSK9 plasma levels did not correlate with kidney function. Furthermore, PCSK9 plasma concentrations were not associated with cardiovascular events in patients with reduced renal function. PMID:26799206

    Recent clinical studies have revealed that the expression of endoglin, an accessory protein for the TGF-β receptor, is increased in patients with atherosclerotic diseases. The plasma endoglin level is thought to represent endothelial activation, inflammation, and senescence. To clarify the significance of plasma endoglin in chronic coronary artery disease. Human umbilical vein endothelial cells (HUVECs) were cultured to examine changes in soluble endoglin (s-endoglin) levels caused by atherogenic stimulation in vitro. We studied 318 patients with stable coronary artery disease who underwent a successful percutaneous coronary intervention (PCI). Patients with acute coronary syndrome were excluded. Major adverse cardiovascular events (MACE) were congestive heart failure, acute myocardial infarction, stroke, and sudden cardiac death. All patients were followed-up to examine MACE after the procedure. We confirmed that the levels of s-endoglin was increased in the culture medium of HUVECs by senescence, tumor necrosis factor-α and hydrogen peroxide. In a clinical study, mean follow-up period was 1055 ± 612 days (49-2136 days) with 27 incidents of MACE (8.5%). We divided patients into three groups according to the plasma s-endoglin levels. Kaplan-Meier curves revealed that the highest endoglin group had a significantly higher MACE rate than the lowest endoglin group (log-rank test, p = 0.009). A Cox proportional hazards model showed that chronic kidney disease, left ventricular ejection fraction and s-endoglin level were significant factors to predict MACE. Plasma endoglin could be a marker to predict cardiovascular events in patients with chronic coronary artery disease after PCI. PMID:21667051

    Metabolic syndrome (MetS) associates with cardiovascular risk post-kidney transplantation, but its ambiguity impairs understanding of its diagnostic utility relative to components. We compared five MetS definitions and the predictive value of constituent components of significant definitions for major adverse cardiovascular events (MACE) in a cohort of 1182 kidney transplant recipients. MetS definitions were adjusted for noncomponent traditional Framingham risk factors and relevant transplant-related variables. Kaplan-Meier, logistic regression, and Cox proportional hazards analysis were utilized. There were 143 MACE over 7447 patient-years of follow-up. Only the World Health Organization (WHO) 1998 definition predicted MACE (25.3 vs 15.5 events/1000 patient-years, P = 0.019). Time-to-MACE was 5.5 ± 3.5 years with MetS and 6.8 ± 3.9 years without MetS (P < 0.0001). MetS was independent of pertinent MACE risk factors except age and previous cardiac disease. Among MetS components, dysglycemia provided greatest hazard ratio (HR) for MACE (1.814 [95% confidence interval 1.26-2.60]), increased successively by microalbuminuria (HR 1.946 [1.37-2.75]), dyslipidemia (3.284 [1.72-6.26]), hypertension (4.127 [2.16-7.86]), and central obesity (4.282 [2.09-8.76]). MetS did not affect graft survival. In summary, although the WHO 1998 definition provides greatest predictive value for post-transplant MACE, most of this is conferred by dysglycemia and is overshadowed by age and previous cardiac disease.

    Background Legislations banning smoking in indoor public places and workplaces are being implemented worldwide to protect the population from secondhand smoke exposure. Several studies have reported reductions in hospitalizations for acute coronary events following the enactment of smoke-free laws. Objective We set out to conduct a systematic review and meta-analysis of epidemiologic studies examining how legislations that ban smoking in indoor public places impact the risk of acute coronary events. Methods We searched MEDLINE, EMBASE, and relevant bibliographies including previous systematic reviews for studies that evaluated changes in acute coronary events, following implementation of smoke-free legislations. Studies were identified through December 2013. We pooled relative risk (RR) estimates for acute coronary events comparing post- vs. pre-legislation using inverse-variance weighted random-effects models. Results Thirty-one studies providing estimates for 47 locations were included. The legislations were implemented between 1991 and 2010. Following the enactment of smoke-free legislations, there was a 12 % reduction in hospitalizations for acute coronary events (pooled RR: 0.88, 95 % CI: 0.85–0.90). Reductions were 14 % in locations that implemented comprehensive legislations compared to an 8 % reduction in locations that only had partial restrictions. In locations with reductions in smoking prevalence post-legislation above the mean (2.1 % reduction) there was a 14 % reduction in events compared to 10 % in locations below the mean. The RRs for acute coronary events associated with enacting smoke-free legislation were 0.87 vs. 0.89 in locations with smoking prevalence pre-legislation above and below the mean (23.1 %), and 0.87 vs. 0.89 in studies from the Americas vs. other regions. Conclusion The implementation of smoke-free legislations was related to reductions in acute coronary event hospitalizations in most populations evaluated. Benefits are greater

    Introduction: The determination of inflammation markers in circulation has enabled an important improvement in the study of cardiovascular diseases. It was tested the hypothesis that non-specific markers such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and fibrinogen may provide prognostic information in patients with acute myocardial infarction with persistent ST-segment elevation (STEMI) undergoing primary angioplasty (PCI). Methods: Patients: A cohort of 197 consecutive patients with STEMI undergoing primary PCI was enrolled, evaluating during hospitalization, the peak values of the following markers of inflammation: ESR, CRP and fibrinogen. A telephone follow-up has been made in order to investigate any possible new cardiovascular events after hospital discharge and the procedure performed. Results: Higher values of CRP were statistically associated with adverse future events as composite endpoint and with the single endpoint of death. Furthermore, higher age, presence of hypertension, history of previous cardiovascular events, were statistically significantly associated with cardiac events at follow up. In this group were also overrepresented subjects with anterior myocardial infarction in the anterior localization and with an EF ≤ 35% at discharge. Conclusions: CRP appears to be a predictor of future cardiovascular events, confirming that a pro-inflammatory state promotes the progression of atherosclerotic disease and its complications.

    Diabetic kidney disease leads to microalbuminuria and gradually progresses to overt proteinuria with renal insufficiency. Recent studies have demonstrated that 20% to 40% of patients with diabetic kidney disease are normo- to microalbuminuric, despite reduced renal function. We investigated renal and cardiovascular outcomes in patients with diabetes and renal insufficiency who were normo-, micro-, and macroalbuminuric. Patients with diabetes and stage III or IV chronic kidney disease were recruited and divided into normoalbuminuric, microalbuminuric, and macroalbuminuric groups. New-onset cardiovascular events and renal outcomes, defined by end-stage renal disease or a 50% decline in estimated glomerular filtration rate, were evaluated. Among the 1136 study patients, 255 (22.4%) were normoalbuminuric. During a mean follow-up duration of 44 months, the incidence of cardiovascular disease was similar among groups (P = 0.68). However, renal outcomes were significantly more common in patients with macroalbuminuria than in those who were normoalbuminuric or microalbuminuric (P < 0.001). Multivariate Cox analysis identified macroalbuminuria and estimated glomerular filtration rate as independent predictors of renal outcomes. The amount of albuminuria was not associated with cardiovascular events in this population. Although cardiovascular events were similar in patients with diabetic kidney disease and renal insufficiency, renal outcomes differed significantly according to the amount of albuminuria.

    BackgroundPeripheral arterial disease (PAD) is commonly associated with a high cardiovascular mortality and morbidity as a marker of plurifocal atherosclerosis. Whether exercise thallium perfusion muscular asymmetry in the legs associated with PAD has prognostic value is unknown. Such a hypothesis was evaluated in a prospective study which remains the gold standard in clinical research. Methods and resultsScintigraphic calf perfusion symmetry after exercise (SCPSE) was measured at the end of a maximal or symptom-limited treadmill exercise test in 358 patients with known or suspected coronary artery disease (CAD). During the follow-up period (mean 85.3±32.8 months), 93 cardiovascular events and deaths (incident cases) occurred. Among those incident cases, the percentage of subjects with higher SCPSE values (third tertile) was 45.2%, versus 29.1% in controls (lower tertiles) ( p=0.005). In stepwise multivariate analysis performed with the Cox proportional hazards model, previous CAD and SCPSE were the only significant independent predictors of prognosis. The multivariate relative risk of cardiovascular death or event in subjects with higher values of SCPSE was 1.94 (95% CI: 1.15-3.21; p<0.01). ConclusionsScintigraphic calf perfusion asymmetry after exercise was independently associated with incident cardiovascular events in high-risk subjects. This index, which is easily and quickly calculated, could be used for evaluation of cardiovascular risk.

    Background Argentina’s congress passed a tobacco control law that would enforce 100% smoke-free environments for the entire country, strong and pictorial health warnings on tobacco products and a comprehensive advertising ban. However, the Executive Branch continues to review the law and it has not been fully implemented. Our objective was to project the potential impact of full implementation of this tobacco control legislation on cardiovascular disease. Methods The Coronary Heart Disease (CHD) Policy Model was used to project future cardiovascular events. Data sources for the model included vital statistics, morbidity and mortality data, and tobacco use estimates from the National Risk Factor Survey. Estimated effectiveness of interventions was based on a literature review. Results were expressed as life-years, myocardial infarctions and strokes saved in an 8-year-period between 2012 and 2020. In addition we projected the incremental effectiveness on the same outcomes of a tobacco price increase not included in the law. Results In the period 2012–2020, 7500 CHD deaths, 16 900 myocardial infarctions and 4300 strokes could be avoided with the full implementation and enforcement of this law. Annual per cent reduction would be 3% for CHD deaths, 3% for myocardial infarctions and 1% for stroke. If a tobacco price increase is implemented the projected avoided CHD deaths, myocardial infarctions and strokes would be 15 500, 34 600 and 11 900, respectively. Conclusions Implementation of the tobacco control law would produce significant public health benefits in Argentina. Strong advocacy is needed at national and international levels to get this law implemented throughout Argentina. PMID:23092886

  8. Predictors of the first cardiovascular event in patients with systemic lupus erythematosus - a prospective cohort study

    PubMed Central

    2009-01-01

    Introduction Cardiovascular disease (CVD) is a major cause of premature mortality among Systemic lupus erythematosus (SLE) patients. Many studies have measured and evaluated risk factors for premature subclinical atherosclerosis, but few studies are prospective and few have evaluated risk factors for hard endpoints, i.e. clinically important cardiovascular events (CVE). We investigated the impact of traditional and lupus associated risk factors for the first ever CVE in a longitudinal cohort of SLE patients. Methods A total of 182 SLE patients (mean age 43.9 years) selected to be free of CVE were included. Cardiovascular and autoimmune biomarkers were measured on samples collected after overnight fasting at baseline. Clinical information was collected at baseline and at follow up. End point was the first ever CVE (ischemic heart, cerebrovascular or peripheral vascular disease or death due to CVD). Impact of baseline characteristics/biomarkers on the risk of having a first CVE was evaluated with Cox regression. Results Follow up was 99.5% after a mean time of 8.3 years. Twenty-four patients (13%) had a first CVE. In age-adjusted Cox regression, any positive antiphospholipid antibody (aPL), elevated markers of endothelial activation (von Willebrand factor (vWf), soluble vascular cellular adhesion molecule-1 (sVCAM-1)) and fibrinogen predicted CVEs. Of SLE manifestations, arthritis, pleuritis and previous venous occlusion were positively associated with future CVEs while thrombocytopenia was negatively associated. Among traditional risk factors only age and smoking were significant predictors. In a multivariable Cox regression model age, any positive aPL, vWf and absence of thrombocytopenia were all predictors of the first CVE. Conclusions In addition to age, positive aPL, biomarkers indicating increased endothelial cell activity/damage, and absence of thrombocytopenia were independent predictors of CVEs in this prospective study. Our results indicate that activation

    Context. The use of thiazolidinediones (TZDs) in patients with type-2 diabetes mellitus appears to be associated with an increased risk of myocardial infarction (MI) compared with placebo or other oral antidiabetic drug regimens. Objective. We conducted a study to investigate whether there was a difference in the risk of acute MI and hemorrhagic and non-hemorrhagic stroke between specific TZDs, namely rosiglitazone maleate (Avandia) and pioglitazone (Actos), and other oral antidiabetic agents in a high-risk, largely underrepresented and largely minority Medicaid population. Study Design, Setting, and Patients. We analyzed patient encounter data using propensity-scoring methods and logistic regression to compare the risk of cardiovascular (CV) events in patients with type-2 diabetes in a high-risk population. Main Outcome Measures. Outcomes were identified through International Classification of Disease (ICD-9) codes 410–411 for acute MI; 430–438 for stroke; and revenue (emergency department) codes 450–459 in the case of MI. Results. Using retrospective medical encounter and prescription data analyses, we found that rosiglitazone, compared with other oral antidiabetic agents, was associated with an increased rate of CV events by 20% in a high-risk cohort of diabetic patients. Neither pioglitazone nor the TZD drug class as a whole was associated with an increased CV risk. Conclusion. Rosiglitazone was associated with a significant increase in CV events (MI and stroke) among high-risk patients with type-2 diabetes, whereas pioglitazone was not. We recommend further research to capture risk factors that were not observed in our encounter data. PMID:20140111

    Features of metabolic syndrome are not uncommon in patients after liver transplantation. To examine the prevalence and risk factors of posttransplantation metabolic syndrome (PTMS), the files of 252 transplant recipients (mean age, 54.5 ± 2.8 years, 57.9% male) were reviewed for pretransplant and posttransplant clinical and laboratory parameters (mean follow-up, 6.2 ± 4.4 years). Rates of obesity (body mass index >30 kg/m(2) ), hypertriglyceridemia (>150 mg/dL), high-density lipoprotein cholesterol <40 mg/dL (men) or <50 mg/dL (women), hypertension, and diabetes were significantly higher after transplantation than before. Metabolic syndrome was diagnosed in 5.4% of patients before transplantation and 51.9% after. Besides significantly higher rates of the typical metabolic derangements (P < 0.0001), the patients with PTMS were older and heavier than those without PTMS, and they had a higher rate of pretransplant hepatitis C virus infection (P < 0.03) and more posttransplant major vascular and cardiac events (20 events in 15.2% of patients with PTMS versus 6 events in 4.9% of patients without PTMS; P < 0.007). There was no between-group difference in mortality or causes of death (mainly related to recurrent disease, graft failure, and sepsis). Significant independent predictors of PTMS on logistic regression analysis were age (odds ratio [OR] = 1.04), pretransplant nonalcoholic fatty liver disease (OR = 3.4), body mass index (OR = 1.13), diabetes (OR = 5.95), and triglycerides (OR = 1.01). The rate of metabolic syndrome in liver transplant recipients is more than twice that reported for the general population. PTMS is associated with cardiovascular morbidity but not mortality, and it may be predicted by pretransplantation conditions. Prospective studies are required to determine the significance and management of PTMS. PMID:21254340

    Objectives To identify and characterize an association between persistent asthma and cardiovascular disease (CVD) risk in the Multi-Ethnic Study of Atherosclerosis (MESA). Approach and Results MESA is a longitudinal prospective study of an ethnically diverse cohort of individuals free of known CVD at its inception. Presence and severity of asthma were assessed in the MESA at Exam 1. Persistent asthma was defined as asthmatics using controller medications (inhaled corticosteroids, leukotriene inhibitors, oral corticosteroids) and intermittent asthma as asthmatics not using controller medications. Participants were followed for a mean (standard deviation) 9.1 (2.8) years for development of incident CVD (coronary death, myocardial infarction, angina, stroke, and CVD death). Multivariable Cox regression models were used to assess associations of asthma and CVD. The 6,792 participants were 62.2 (standard deviation 10.2) years old: 47% male (28% African-American, 22% Hispanic, 12% Chinese). Persistent asthmatics (N=156), compared to intermittent (N=511) and non-asthmatics (N=6125), respectively had higher C-reactive protein (1.2 [1.2] vs 0.9 [1.2] vs 0.6 [1.2] mg/L) and fibrinogen (379 [88] vs 356 [80] vs 345 [73] mg/dL) levels. Persistent asthmatics had the lowest unadjusted CVD-free survival rate of 84.1%, 95% confidence interval (78.9–90.3%) compared with intermittent asthmatics 91.1% (88.5–93.8%) and non-asthmatics 90.2% (89.4–91%). Persistent asthmatics had greater risk of CVD events than non-asthmatics (HR 1.6 [95% 1.01–2.5, p=0.040]), even after adjustment for age, sex, race, CVD risk factors, and anti-hypertensive and lipid medication use. Conclusions In this large multi-ethnic cohort, persistent asthmatics had a higher CVD event rate than non-asthmatics. PMID:25908767

    The aim of the present study was to define the prevalence, characteristics, risk factors and impact on clinical outcomes of acute myocardial infarction (AMI) versus other cardiovascular events (CVEs) in patients with community-acquired pneumonia (CAP). This was an international, multicentre, observational, prospective study of CAP patients hospitalised in eight hospitals in Italy and Switzerland. Three groups were identified: those without CVEs, those with AMI and those with other CVEs. Among 905 patients, 21 (2.3%) patients experienced at least one AMI, while 107 (11.7%) patients experienced at least one other CVE. Patients with CAP and either AMI or other CVEs showed a higher severity of the disease than patients with CAP alone. Female sex, liver disease and the presence of severe sepsis were independent predictors for the occurrence of AMI, while female sex, age >65 years, neurological disease and the presence of pleural effusion predicted other CVEs. In-hospital mortality was significantly higher among those who experienced AMI in comparison to those experiencing other CVEs (43% versus 21%, p=0.039). The presence of AMI showed an adjusted odds ratio for in-hospital mortality of 3.57 (p=0.012) and for other CVEs of 2.63 (p=0.002). These findings on AMI versus other CVEs as complications of CAP may be important when planning interventional studies on cardioprotective medications.

    Prediction of ischemic cardiovascular events (ICE) in acromegalic patients stratified accordingly with Framingham (FS) and Agatston score (AS). 32 patients with active (group A (0)) and 20 with controlled (group B (0)) acromegaly have been enrolled. During the 5-year follow-up, 19 out of 32 patients in group A (0) reached disease control. At entry, FS and AS, by an eight-slice MDCT scanner, were calculated in all patients. ICE were diagnosed by autopsy, if lethal, and by electrocardiography and/or echocardiography, if non-lethal. Overall, 9.6 % of patients died for lethal ICE. AS >400, but not high FS at entry, was associated with increased risk of lethal ICE. Lethal ICE had occurred in two patients of group A (0) and three of group B (0) (p NS), while a non-lethal ICE had occurred in two cases of the former and in other two of the latter group (p NS). Either FS or AS was correlated with the risk for ICE overall (p < 0.02), but only AS correlated with that of lethal ICE (p < 0.0003). Survival analysis demonstrated reduced life expectancy in patients with high FS (p < 0.02). In acromegalics, AS >400 is associated with increased risk of lethal ICE, while high FS is associated with reduced life expectancy, regardless of disease control.

    Background Hemorheological and glycemic parameters and high density lipoprotein (HDL) cholesterol are used as biomarkers of atherosclerosis and thrombosis. Objective To investigate the association and clinical relevance of erythrocyte sedimentation rate (ESR), fibrinogen, fasting glucose, glycated hemoglobin (HbA1c), and HDL cholesterol in the prediction of major adverse cardiovascular events (MACE) and coronary heart disease (CHD) in an outpatient population. Methods 708 stable patients who visited the outpatient department were enrolled and followed for a mean period of 28.5 months. Patients were divided into two groups, patients without MACE and patients with MACE, which included cardiac death, acute myocardial infarction, newly diagnosed CHD, and cerebral vascular accident. We compared hemorheological and glycemic parameters and lipid profiles between the groups. Results Patients with MACE had significantly higher ESR, fibrinogen, fasting glucose, and HbA1c, while lower HDL cholesterol compared with patients without MACE. High ESR and fibrinogen and low HDL cholesterol significantly increased the risk of MACE in multivariate regression analysis. In patients with MACE, high fibrinogen and HbA1c levels increased the risk of multivessel CHD. Furthermore, ESR and fibrinogen were significantly positively correlated with HbA1c and negatively correlated with HDL cholesterol, however not correlated with fasting glucose. Conclusion Hemorheological abnormalities, poor glycemic control, and low HDL cholesterol are correlated with each other and could serve as simple and useful surrogate markers and predictors for MACE and CHD in outpatients.

    Patients with systemic lupus erythematosus (SLE) are at excess risk of cardiovascular events (CVEs). There is uncertainty regarding the relative importance of SLE disease activity, medications, or traditional risk factors in this increased risk. To gain insight into this, the authors analyzed data from a cohort of 1,874 patients with SLE who were seen quarterly at a single clinical center (April 1987–June 2010) using pooled logistic regression analysis. In 9,485 person-years of follow-up, the authors observed 134 CVEs (rate = 14.1/1,000 person-years). This was 2.66 times what would be expected in the general population based on Framingham risk scores (95% confidence interval: 2.16, 3.16). After adjustment for age, CVE rates were not associated with duration of SLE. However, they were associated with average past levels of SLE disease activity and recent levels of circulating anti-double-stranded DNA. Past use of corticosteroids (in the absence of current use) was not associated with CVE rates. However, persons currently using 20 mg/day or more of corticosteroids had a substantial increase in risk even after adjustment for disease activity. Thus, consistent with findings in several recent publications among cohorts with other diseases, current use of corticosteroids was associated with an increased risk of CVEs. These results suggest a short-term impact of corticosteroids on CVE risk. PMID:23024137

    2013-01-01

    The term decline effect is referred to a diminution of scientifically discovered effects over time. Reasons for the decline effect are multifaceted and include publication bias, selective reporting, outcomes reporting bias, regression to the mean, scientific paradigm shift, overshadowing and habituation, among others. Such effects can be found in cardiovascular medicines through medications (e.g., aspirin, antithrombotics, proton pump inhibitor, beta-blockers, statins, estrogen/progestin, angiotensin converting enzyme inhibitor etc.), as well as with interventional devices (e.g., angioplasty, percutaneous coronary intervention, stents). The scientific community should understand the various dimensions of the decline effects, and effective steps should be undertaken to prevent or recognize such decline effects in cardiovascular medicines.

    Masked hypertension, defined as nonelevated clinic blood pressure (BP) with elevated out-of-clinic BP, has been associated with increased cardiovascular disease (CVD) risk in Europeans and Asians. Few data are available on masked hypertension and CVD and mortality risk among blacks. We analyzed data from the Jackson Heart Study, a prospective cohort study of blacks. Analyses included participants with clinic-measured systolic/diastolic BP <140/90 mm Hg who completed ambulatory BP monitoring after the baseline examination in 2000 to 2004 (n=738). Masked daytime (10:00 am-8:00 pm) hypertension was defined as mean ambulatory systolic/diastolic BP ≥135/85 mm Hg. Masked nighttime (midnight to 6:00 am) hypertension was defined as mean ambulatory systolic/diastolic BP ≥120/70 mm Hg. Masked 24-hour hypertension was defined as mean systolic/diastolic BP ≥130/80 mm Hg. CVD events (nonfatal/fatal stroke, nonfatal myocardial infarction, or fatal coronary heart disease) and deaths identified through December 2010 were adjudicated. Any masked hypertension (masked daytime, nighttime, or 24-hour hypertension) was present in 52.2% of participants; 28.2%, 48.2% and 31.7% had masked daytime, nighttime, and 24-hour hypertension, respectively. There were 51 CVD events and 44 deaths during a median follow-up of 8.2 and 8.5 years, respectively. CVD rates per 1000 person-years (95% confidence interval) in participants with and without any masked hypertension were 13.5 (9.9-18.4) and 3.9 (2.2-7.1), respectively. The multivariable adjusted hazard ratio (95% confidence interval) for CVD was 2.49 (1.26-4.93) for any masked hypertension and 2.86 (1.59-5.13), 2.35 (1.23-4.50), and 2.52 (1.39-4.58) for masked daytime, nighttime, and 24-hour hypertension, respectively. Masked hypertension was not associated with all-cause mortality. Masked hypertension is common and associated with increased risk for CVD events in blacks. PMID:27354424

    Over one billion Muslims worldwide fast during the month of Ramadan. Ramadan fasting brings about some changes in the daily lives of practicing Muslims, especially in their diet and sleep patterns, which are associated with the risk of cardiovascular diseases. Over the years, many original studies have made the effort to identify the possible impact of the Ramadan fast on cardiovascular diseases. This systematic review and meta-analysis is an attempt to present the summary of key findings from those articles and an appraisal of selected literature. A systematic search using keywords of “;Ramadan fasting” and “;cardiovascular diseases” was conducted in primary research article and gray-literature repositories, in combination with hand searching and snow balling. Fifteen studies were finally selected for data extraction on the outcomes of stroke, myocardial infarction, and congestive heart failure. The analysis revealed that the incidence of cardiovascular events during the Ramadan fast was similar to the nonfasting period. Ramadan fast is not associated with any change in incidence of acute cardiovascular disease. PMID:27186152

    Over one billion Muslims worldwide fast during the month of Ramadan. Ramadan fasting brings about some changes in the daily lives of practicing Muslims, especially in their diet and sleep patterns, which are associated with the risk of cardiovascular diseases.

    Objective Insulin resistance (IR) and cardiovascular disease (CVD) share a common soil. We investigated the combined role of single nucleotide polymorphisms (SNPs) affecting insulin signaling (ENPP1 K121Q, rs1044498; IRS1 G972R, rs1801278; TRIB3 Q84R, rs2295490) on CVD, age at myocardial infarction (MI), in vivo insulin sensitivity and in vitro insulin-stimulated nitric oxide synthase (NOS) activity. Design and Setting 1. We first studied, incident cardiovascular events (a composite endpoint comprising myocardial infarction -MI-, stroke and cardiovascular death) in 733 patients (2,186 person-years, 175 events). 2. In a replication attempt, age at MI was tested in 331 individuals. 3. OGTT-derived insulin sensitivity index (ISI) was assessed in 829 individuals with fasting glucose < 126 mg/dl. 4. NOS activity was measured in 40 strains of human vein endothelial cells (HUVECs). Results 1. Risk variants jointly predicted cardiovascular events (HR=1.181; p=0.0009) and, when added to clinical risk factors, significantly improved survival C-statistics; they also allowed a significantly correct reclassification (by net reclassification index) in the whole sample (135/733 individuals) and, even more, in obese patients (116/204 individuals). 2. Risk variants were jointly associated with age at MI (p=0.006). 3. A significant association was also observed with ISI (p=0.02). 4. Finally, risk variants were jointly associated with insulin-stimulated NOS activity in HUVECs (p=0.009). Conclusions Insulin signaling genes variants jointly affect cardiovascular disease, very likely by promoting whole body and endothelium-specific insulin resistance. Further studies are needed to address whether their genotyping help identify very high-risk patients who need specific and/or more aggressive preventive strategies. PMID:23107043

    Objective Adverse cardiovascular events (ACVEs) account for a large proportion of the morbidities and mortalities associated with drug overdose emergencies. However, there are no published reports regarding outcomes of ACVEs associated with acute dapsone poisoning. Here, the authors retrospectively analyzed ACVEs reported within 48 hours of treatment in patients with acute dapsone poisoning and assessed the significance of ACVEs as early predictors of mortality. Methods Sixty-one consecutive cases of acute dapsone poisoning that were diagnosed and treated at a regional emergency center between 2006 and 2014 were included in the study. An ACVE was defined as myocardial injury, shock, ventricular dysrhythmia, cardiac arrest, or any combination of these occurring within the first 48 hours of treatment for acute dapsone poisoning. Results Nineteen patients (31.1%) had evidence of myocardial injury (elevation of serum troponin-I level or electrocardiography signs of ischemia) after dapsone overdose, and there were a total of 19 ACVEs (31.1%), including one case of shock (1.6%). Fourteen patients (23.0%) died from pneumonia or multiple organ failure, and the incidence of ACVEs was significantly higher among non-survivors than among survivors (64.3% vs. 21.3%, P=0.006). ACVE was a significant predictor of mortality (odds ratio, 5.690; 95% confidence interval, 1.428 to 22.675; P=0.014). Conclusion The incidence of ACVE was significantly higher among patients who died after acute dapsone poisoning. ACVE is a significant predictor of mortality after dapsone overdose, and evidence of ACVE should be carefully sought in these patients. PMID:27752614

    Objectives It was recently demonstrated that adverse cardiovascular events (ACVE) complicate a high proportion of hospitalizations for patients with acute drug overdoses. The aim of this study was to derive independent clinical risk factors for ACVE in patients with acute drug overdoses. Methods This prospective cohort study was conducted over 3 years at two urban university hospitals. Patients were adults with acute drug overdoses enrolled from the ED. In-hospital ACVE was defined as any of myocardial injury, shock, ventricular dysrhythmia, or cardiac arrest. Results There were 1,562 patients meeting inclusion/exclusion criteria (mean age, 41.8 years; female, 46%; suicidal, 38%). ACVE occurred in 82 (5.7%) patients (myocardial injury, 61; shock, 37; dysrhythmia, 23; cardiac arrests, 22) and there were 18 (1.2%) deaths. On univariate analysis, ACVE risk increased with age, lower serum bicarbonate, prolonged QTc interval, prior cardiac disease, and altered mental status. In a multivariable model adjusting for these factors as well as patient sex and hospital site, independent predictors were: QTc > 500 msec (3.8% prevalence, odds ratio [OR] 27.6), bicarbonate < 20 mEql/L (5.4% prevalence, OR 4.4), and prior cardiac disease (7.1% prevalence, OR 9.5). The derived prediction rule had 51.6% sensitivity, 93.7% specificity, and 97.1% negative predictive value; while presence of two or more risk factors had 90.9% positive predictive value. Conclusions The authors derived independent clinical risk factors for ACVE in patients with acute drug overdose, which should be validated in future studies as a prediction rule in distinct patient populations and clinical settings.

    Calcium burden determined in CT images acquired in lung cancer screening is a strong predictor of cardiovascular events (CVEs). This study investigated whether subjects undergoing such screening who are at risk of a CVE can be identified using automatic image analysis and subject characteristics. Moreover, the study examined whether these individuals can be identified using solely image information, or if a combination of image and subject data is needed. A set of 3559 male subjects undergoing Dutch-Belgian lung cancer screening trial was included. Low-dose non-ECG synchronized chest CT images acquired at baseline were analyzed (1834 scanned in the University Medical Center Groningen, 1725 in the University Medical Center Utrecht). Aortic and coronary calcifications were identified using previously developed automatic algorithms. A set of features describing number, volume and size distribution of the detected calcifications was computed. Age of the participants was extracted from image headers. Features describing participants' smoking status, smoking history and past CVEs were obtained. CVEs that occurred within three years after the imaging were used as outcome. Support vector machine classification was performed employing different feature sets using sets of only image features, or a combination of image and subject related characteristics. Classification based solely on the image features resulted in the area under the ROC curve (Az) of 0.69. A combination of image and subject features resulted in an Az of 0.71. The results demonstrate that subjects undergoing lung cancer screening who are at risk of CVE can be identified using automatic image analysis. Adding subject information slightly improved the performance.

    Early mortality is high in hemodialysis (HD) patients, but little is known about early cardiovascular event (CVE) rates after HD initiation. To study this we analyzed data in the AROii cohort of incident HD patients from over 300 European Fresenius Medical Care dialysis centers. Weekly rates of a composite of CVEs during the first year and monthly rates of the composite and its constituents (coronary artery, cerebrovascular, peripheral arterial, congestive heart failure, and sudden cardiac death) during the first 2 years after HD initiation were assessed. Of 6308 patients that started dialysis within 7 days, 1449 patients experienced 2405 CVEs over the next 2 years. The first-year CVE rate (30.2/100 person-years; 95% CI, 28.7-31.7) greatly exceeded the second-year rate (19.4/100; 95% CI, 18.1-20.8). Composite CVEs were highest during the first week with increased risk compared with the second year, persisting until the fifth month. Except for sudden cardiac death, temporal patterns of rates for all CVE categories were very similar, with highest rates during the first month and a high-risk period extending to 4 months. Higher or lower cumulative weekly dialysis dose, lower blood flow, and lower net ultrafiltration during dialysis were associated with CVE during the high-risk period, but not during the post high-risk period. Thus, the incidence of CVE in the first weeks after HD initiation is much higher than during subsequent periods which raises concerns that HD initiation may trigger CVEs.

  8. 10-year survival of total ankle arthroplasties

    PubMed Central

    2011-01-01

    Background and purpose There is an ongoing need to review large series of total ankle replacements (TARs) for monitoring of changes in practice and their outcome. 4 national registries, including the Swedish Ankle Register, have previously reported their 5-year results. We now present an extended series with a longer follow-up, and with a 10-year survival analysis. Patients and methods Records of uncemented 3-component TARs were retrospectively reviewed, determining risk factors such as age, sex, and diagnosis. Prosthetic survival rates were calculated with exchange or removal of components as endpoint—excluding incidental exchange of the polyethylene meniscus. Results Of the 780 prostheses implanted since 1993, 168 (22%) had been revised by June 15, 2010. The overall survival rate fell from 0.81 (95% CI: 0.79–0.83) at 5 years to 0.69 (95% CI: 0.67–0.71) at 10 years. The survival rate was higher, although not statistically significantly so, during the latter part of the period investigated. Excluding the STAR prosthesis, the survival rate for all the remaining designs was 0.78 at 10 years. Women below the age of 60 with osteoarthritis were at a higher risk of revision, but age did not influence the outcome in men or women with rheumatoid arthritis. Revisions due to technical mistakes at the index surgery and instability were undertaken earlier than revisions for other reasons. Interpretation The results have slowly improved during the 18-year period investigated. However, we do not believe that the survival rates of ankle replacements in the near future will approach those of hip and knee replacements—even though improved instrumentation and design of the prostheses, together with better patient selection, will presumably give better results.

    Unhealthy lifestyle habits are a major contributor to coronary artery disease. The purpose of the present study was to investigate the associations of smoking, weight maintenance, physical activity, and diet with coronary calcium, cardiovascular events, and mortality. US participants who were 44-84 years of age (n = 6,229) were followed in the Multi-Ethnic Study of Atherosclerosis from 2000 to 2010. A lifestyle score ranging from 0 to 4 was created using diet, exercise, body mass index, and smoking status. Coronary calcium was measured at baseline and a mean of 3.1 (standard deviation, 1.3) years later to assess calcium progression. Participants who experienced coronary events or died were followed for a median of 7.6 (standard deviation, 1.5) years. Participants with lifestyle scores of 1, 2, 3, and 4 were found to have mean adjusted annual calcium progressions that were 3.5 (95% confidence interval (CI): 0.0, 7.0), 4.2 (95% CI: 0.6, 7.9), 6.8 (95% CI: 2.0, 11.5), and 11.1 (95% CI: 2.2, 20.1) points per year slower, respectively, relative to the reference group (P = 0.003). Unadjusted hazard ratios for death by lifestyle score were as follows: for a score of 1, the hazard ratio was 0.79 (95% CI: 0.61, 1.03); for a score of 2, the hazard ratio was 0.61 (95% CI: 0.46, 0.81); for a score of 3, the hazard ratio was 0.49 (95% CI: 0.32, 0.75); and for a score of 4, the hazard ratio was 0.19 (95% CI: 0.05, 0.75) (P < 0.001 by log-rank test). In conclusion, a combination of regular exercise, healthy diet, smoking avoidance, and weight maintenance was associated with lower coronary calcium incidence, slower calcium progression, and lower all-cause mortality over 7.6 years.

    Lung transplantation is a well-established treatment for advanced lung diseases. In children, the diseases that most commonly lead to the need for a transplantation are cystic fibrosis, pulmonary hypertension, and bronchiolitis. However, the number of pediatric lung transplantations being performed is low compared with the number of transplants performed in the adult age group. The objective of this study was to demonstrate our experience with pediatric lung transplants over a 10-year period in a program initially designed for adults. PMID:24860860

    The role of mitochondria in oxidative stress is well recognized, but many questions are still to be answered. This article is intended to update our comprehensive review in 2005 by highlighting the progress in understanding of mitochondrial reactive oxygen species (ROS) metabolism over the past 10 years. We review the recently identified or re-appraised sources of ROS generation in mitochondria, such as p66shc protein, succinate dehydrogenase, and recently discovered properties of the mitochondrial antioxidant system. We also reflect upon some controversies, disputes, and misconceptions that confound the field. PMID:26071769

    Previous studies have shown that Japanese taxi drivers are exposed to more risk factors and have a higher mortality rate due to cardiovascular disease than other occupational groups. We investigated the effect of night taxi driving with a view to preventing acute events of cardiovascular disease among aged taxi drivers. Twenty-nine taxi drivers (41-67 years old) were examined for urine normetanephrine/creatinine, von Willebrand factor, anti-thrombin III, t-plasminogen activator-plasminogen activator inhibitor 1-complex, hematocrit, blood glucose and blood pressure in the morning and at midnight during a duty day and in the following morning. At the same time, the blood pressure and blood glucose of 46 taxi drivers (43-67 years old) in the morning after a night duty with little sleep and in the morning after daytime work and subsequent night sleep were compared. The results obtained indicate that the aggravation of sympathetic nervous system functions with disturbed circadian rhythms, increased blood coagulation and blood concentration, endothelial injury and the elevation of blood glucose at midnight or the next morning were induced by their night work. These conditions are supposed to favour acute vascular events in aged taxi drivers. Preventive measures considered include social support for anticoagulant food and water intake, short exercise and walking as well as taking a rest and a nap during night work.

    2015-11-01

    The Trial to Assess Chelation Therapy (TACT) was a randomized double-blind placebo-controlled trial enrolling patients age ≥50 years with prior myocardial infarction. TACT used a 2 × 2 factorial design to study ethylene diamine tetraacetic acid (EDTA) chelation and high-dose vitamin supplementation. Chelation provided a modest but significant reduction in cardiovascular endpoints. The benefit was stronger and significant among participants with diabetes but absent in those without diabetes. Mechanisms by which chelation might reduce cardiovascular risk in persons with diabetes include the effects of EDTA chelation on transition and toxic metals. Transition metals, particularly copper and iron, play important roles in oxidative stress pathways. Toxic metals, in particular cadmium and lead, are toxic for the cardiovascular system. This review discusses the epidemiologic evidence and animal and human studies supporting the role of these metals in the development of diabetes and ischemic heart disease and potential ways by which EDTA chelation could confer cardiovascular benefit.

    The association between single measurements of carotid-femoral pulse wave velocity (cfPWV) and cardiovascular (CV) events is driven by late events beyond 12 months of follow-up. This prospective study compares single measurements of cfPWV vs the 2-year delta cfPWV and the association with short-term development of CV events in hemodialysis patients. cfPWV was performed at t=0 and t=1 two years later, and patients were followed-up for development of CV events through 12 months (n=66). In Cox regression models adjusted for CV risk factors, history of CV events and delta cfPWV remained associated with the development of CV events (hazard ratio for prior CV events=8.9, P=.03; hazard ratio for delta cfPWV=1.14; P=.002). When delta cfPWV was substituted for single cfPWV measurement, none of the single measures were associated with new CV events. The change in cfPWV, but not single measurements of cfPWV, was associated with the development of CV events through 12 months.

    Introduction Glycosylated haemoglobin level (HbA1c) is an indicator of the average blood glucose concentrations over the preceding 2–3 months and is used as a convenient and well-known biomarker in clinical practice. Currently, epidemiological evidence suggests that HbA1c level is an independent risk factor for cardiovascular events such as myocardial infarction, stroke, coronary heart disease and heart failure. This protocol aim is to conduct a systematic review and meta-analysis to determine relationships of HbA1c levels with cardiovascular outcomes and cause of death, and to analyse the range of HbA1c levels that is a predictor of cardiovascular disease and/or mortality based on data from published observational studies. Methods and analysis The search will be conducted using Medline, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Web of Science databases from their inception. Observational studies written in Portuguese, Spanish or English will be included. The Quality In Prognosis Studies tool will be used to assess the risk of bias for the studies included in the systematic review or meta-analysis. HRs for cardiovascular outcomes and causes of death with 95% CIs will be determined as primary outcomes. Subgroup analyses will be performed based on cardiovascular outcomes, cause of death studied, and type of population included in the studies. Ethics and dissemination This systematic review will synthesise evidence on the potential of using HbA1c level as a prognostic marker for cardiovascular disease outcomes and/or mortality. The results will be disseminated by publication in a peer-reviewed journal. Ethics approval will not be needed because the data used for this systematic review will be obtained from published studies and there will be no concerns about privacy.

    Context: Most previous prospective studies suggest that low serum IGF-1 associates with increased risk of cardiovascular disease (CVD) events whereas other studies suggest that high serum IGF-1 associates with increased risk of CVD events. Objective: We tested the hypothesis that not only low, but also high serum IGF-1 levels associate with increased risk of CVD events in elderly men. Setting and Design: Serum IGF-1 levels were measured in 2901 elderly men (age 69–81 years) included in the Swedish cohort of the prospective, population-based Osteoporotic Fractures in Men Study (MrOS), Sweden cohort. Data for CVD events were obtained from national Swedish registers with no loss of followup. Results: During followup (median, 5.1 y) 589 participants experienced a CVD event. The association between serum IGF-1 and risk of CVD events was nonlinear, and restricted cubic spline Cox regression analysis revealed a U-shaped association between serum IGF-1 levels and CVD events (P < .01 for nonlinearity). Low as well as high serum IGF-1 (quintile 1 or 5 vs quintiles 2–4) significantly associated with increased risk for CVD events (hazard ratio [HR] = 1.25, 95% confidence interval, [CI], 1.02–1.54; and HR = 1.35, 95% CI 1.10–1.66, respectively). These associations remained after adjustment for prevalent CVD and multiple risk factors. High serum IGF-1 associated with increased risk of coronary heart disease (CHD) events but not with risk of cerebrovascular events. Conclusions: Both low and high serum IGF-1 levels are risk markers for CVD events in elderly men. The association between high serum IGF-1 and CVD events is mainly driven by CHD events.

    Cardiovascular disease is more common in patients with chronic kidney disease (CKD), and traditional risk factors do not adequately predict those at risk for cardiovascular (CV) events. Recent evidence suggests elevated trimethylamine N-oxide (TMAO), created by gut microflora from dietary L-carnitine and choline, is associated with CV events. We investigated the relationship of TMAO levels in patients with stages 3b and 4 CKD to ischemic CV events using the CanPREDDICT cohort, a Canada-wide observational study with prospective 3-year follow-up of adjudicated CV events. Baseline samples were obtained for 2529 CKD patients. TMAO, choline, and L-carnitine levels were measured using tandem mass spectrometry. Baseline median TMAO level was high for the whole cohort (20.41 μM; interquartile range [IQR]: 12.82-32.70 μM). TMAO was independently associated with CV events (hazard ratio 1.23; 95% confidence interval: 1.06-1.42 / 1 SD lnTMAO) after adjusting for all potential CV risk factors. Those in the highest TMAO quartile had significantly higher risk of CV events (adjusted hazard ratio 1.59; 95% confidence interval: 1.04-2.43; P = 0.0351) in the analysis of recurring ischemic events. Among those with stage 3b CKD (hazard ratio 1.45; 95% confidence interval: 1.12-1.87 / 1 SD lnTMAO), independent of kidney function, TMAO levels identified those at highest risk for events. Our results suggest that TMAO may represent a new potentially modifiable CV risk factor for CKD patients. Further studies are needed to determine sources of variability and if lowering of TMAO reduces CV risk in CKD. PMID:27083288

    Background The role of obesity as a risk factor for cardiovascular disease in patients with chronic kidney disease (CKD) is poorly understood. Waist to hip ratio (WHR) is less influenced by muscle and bone mass than body mass index (BMI).

Setting and Participants Persons with CKD, defined as a baseline estimated glomerular filtration rate between 15 and 60 mL/min/1.73m2, drawn from two community studies: the Atherosclerosis Risk in Communities Study and the Cardiovascular Health Study. Predictor Waist to Hip Ratio, Waist Circumference and Body Mass Index. Outcomes and Measurements Myocardial infarction and fatal coronary heart disease. Results Among 1,669 participants with CKD, mean age was 70.3 years and 56% were women. Mean WHR was 0.97 ± 0.08 in men and 0.90 ± 0.07 in women; mean BMI was 27.2 ± 4.6 kg/m2. Over a mean of 9.3 years of follow-up, there were 334 cardiac events. In multivariable adjusted Cox models the highest WHR group (n=386) was associated with an increased risk of cardiac events compared with the lowest WHR group [HR (95% CI) = 1.36 (1.01–1.83]. Obesity defined by BMI >30 kg/m2 (n= 381) was not associated with cardiac events [HR (95% CI) = 0.86 (0.62–1.20)] in comparison to participants with normal BMI. The results with waist circumference were similar to those with BMI. Limitations Absence of a gold standard for measurement of visceral fat. Conclusions WHR, but not BMI, is associated with cardiac events in persons with CKD. Relying exclusively on BMI may underestimate the importance of obesity as a cardiovascular disease risk factor in persons with CKD. PMID:18514990

    NASA's Aqua spacecraft was launched at 2:55 a.m. on May 4, 2002, from Vandenberg Air Force Base in California, into a near-polar, sun-synchronous orbit at an altitude of 705 km. Aqua carries six Earth-observing instruments to collect data on water in all its forms (liquid, vapor, and solid) and on a wide variety of additional Earth system variables (Parkinson 2003). The design lifetime for Aqua's prime mission was 6 years, and Aqua is now well into its extended mission, approaching 10 years of successful operations. The Aqua data have been used for hundreds of scientific studies and continue to be used for scientific discovery and numerous practical applications.

    Adverse effects of long-term usage of triclosan-containing toothpaste in humans are currently unknown. We assessed the effect of long-term use of 0.3% triclosan-toothpaste on serious adverse events (SAEs) in patients with cardiovascular disease (CVD). 438 patients with a history of stable CVD were entered into the 5-year longitudinal Cardiovascular and Periodontal Study at Prince Charles Hospital, Brisbane, Australia and randomised into test (triclosan) or placebo groups. There were no significant differences in demographics or clinical features between the groups. Patients were examined at baseline, and annually for 5-years. SAEs were classified according to the System Organ Classes defined by MedDRA (Medical Dictionary for Regulatory Activities). Results were analysed using chi square and Kaplan Meier analysis. Overall, 232 patients (123 in the triclosan group; 109 in the placebo group) experienced 569 SAEs (288 in the triclosan group and 281 in the placebo group). There was no significant difference between the groups in numbers of patients experiencing SAEs (p=0.35) or specific cardiovascular SAEs (p=0.82), nor in time to the first SAE or first cardiovascular SAE, irrespective of gender, age or BMI after adjusting for multiple comparisons (p>0.05). The adjusted odds of experiencing an SAE were estimated to increase by 2.7% for each year of age (p=0.02) and the adjusted odds of experiencing a cardiovascular SAE were estimated to increase by 5.1% for each unit increase in BMI (p=0.02). Most cardiovascular events were related to unstable angina or myocardial infarcts, 21 were associated with arrhythmia and 41 were vascular events such as aortic aneurysm and cerebrovascular accident. Within the limitations of the present study the data suggest that the use of triclosan-toothpaste may not be associated with any increase in SAEs in this CVD population. The long-term impact of triclosan on hormone-related disease, such as cancer, in humans remains to be determined

    Decapod crustaceans commonly forage in estuarine environments. The osmoregulatory mechanisms that allow them to cope with periodic episodes of low salinity have been well documented. There is less information on how ventilatory and cardiovascular mechanisms aid survival in low salinity. Prior experiments have shown that most species exhibit a tachycardia coupled with an increase in ventilation rate and oxygen uptake. However, these previous experiments were conducted on animals that were starved before experimentation in order to avoid increases in metabolism associated with digestive processes. This study investigated how the Dungeness crab Cancer magister balances the demands of physiological systems during feeding and digestion in low salinity. Cardiac and ventilatory parameters increased during feeding. When the crabs were subjected to low salinity after feeding, heart rate increased in 25% seawater (SW) but decreased in 50% SW. Instead of an expected increase in ventilation rate during low-salinity exposure, there was a decrease. Feeding was associated with an increase in sternal artery flow, with subsequent decreases in flows through the sternal and anterolateral arteries in low salinity. When low salinity was administered first, a tachycardia occurred, coupled with decreased stroke volume and cardiac output. There was also an increase in ventilation rate. When crabs were fed in low salinity, heart rate decreased in 50% SW but was maintained in 25% SW. Ventilation rate decreased when crabs fed in 50% and 25% SW. Flow through the sternal artery and anterolateral arteries decreased in low salinity, and except for transient increases while feeding, there were further decreases during digestion. Cardiac and ventilatory parameters were rapidly regained when control conditions were restored. The results suggest that events during low salinity are prioritized. Nevertheless, these alterations in physiological parameters may not be beneficial; although digestive

    Alterations in thyroid hormone levels are found associated with inflammation in patients with non-thyroidal illness (NTIS) and are common in patients with type 2 diabetes mellitus (T2DM). Inflammation has also been linked with development of cardiovascular events (CVE) in T2DM. Our objective was to assess whether thyroid hormone abnormalities typical of NTIS in patients with T2DM are related to inflammation and CVE. This was a cross-sectional study of 140 subjects; 70 with T2DM and 70 as a control group paired by age, sex and body mass index (BMI). We recorded age, sex, BMI, waist/hip ratio, diabetes duration, HbA1c, CVE history, serum amyloid A (SAA), TSH, total (T) and free (F) T4 and T3, reverse T3 (rT3) and TT3/rT3 ratio. Patients with T2DM had lower levels of TT4 (p = 0.012), TT3 (p < 0.001), FT3 (p < 0.001) and TT3/rT3 (p = 0.002). They also showed higher FT4 (p < 0.001) and similar TSH levels (p = 0.627) compared to the control group. SAA levels correlated positively with rT3 (r = 0.45; p < 0.001) and inversely with TT3/rT3 (r = -0.38; p = 0.001). Patients with T2DM and history of CVE had higher rT3 (p = 0.006) and lower TT3/rT3 (p = 0.002), along with higher SAA levels (p = 0.002) than patients without this characteristic. Multiple logistic regression showed that factors independently associated with CVE were older age (OR = 1.159, 95 % CI 1.011-1.329), male sex (OR = 4.391, 95 % CI 1.081-17.829) and higher TT3/rT3 (OR = 0.993, 95 % CI 0.987-0.999). We have confirmed the presence of NTIS in T2DM. We also showed that thyroid hormone abnormalities are associated to inflammatory activity and to CVE in these patients.

    Abstract Aim Some previous studies suggest a long term association between clarithromycin use and cardiovascular events. This study investigates this association for clarithromycin given as part of Helicobacter pylori treatment (HPT). Methods Our source population was the Clinical Practice Research Datalink (CPRD), a UK primary care database. We conducted a self‐controlled case series (SCCS), a case–time–control study (CTC) and a propensity score adjusted cohort study comparing the rate of cardiovascular events in the 3 years after exposure to HPT containing clarithromycin with exposure to clarithromycin free HPT. Outcomes were first incident diagnosis of myocardial infarction (MI), arrhythmia and stroke. For the cohort analysis we included secondary outcomes all cause and cardiovascular mortality. Results Twenty‐eight thousand five hundred and fifty‐two patients were included in the cohort. The incidence rate ratio of first MI within 1 year of exposure to HPT containing clarithromycin was 1.07 (95% CI 0.85, 1.34, P = 0.58) and within 90 days was 1.43 (95% CI 0.99, 2.09 P = 0.057) in the SCCS analysis. CTC and cohort results were consistent with these findings. Conclusions There was some evidence for a short term association for first MI but none for a long term association for any outcome.

    Objective Although depression is a risk and prognostic factor for cardiovascular disease (CVD), depression trials involving cardiac patients have not observed the anticipated cardiovascular benefits. To test our hypothesis that depression treatment delivered before clinical CVD onset reduces risk of CVD events, we conducted an 8-year follow-up study of the Indiana sites of the Improving Mood-Promoting Access to Collaborative Treatment (IMPACT) randomized controlled trial. Methods Participants were 235 primary care patients aged ≥60 years with major depression or dysthymia who were randomized to a 12-month collaborative care program involving antidepressants and psychotherapy (85 without and 35 with baseline CVD) or usual care (83 without and 32 with baseline CVD). Hard CVD events (fatal/nonfatal) were identified using electronic medical record and Medicare/Medicaid data. Results 119 patients (51%) had a hard CVD event. As hypothesized, the Treatment x Baseline CVD interaction was significant (p = .021). IMPACT patients without baseline CVD had a 48% lower risk of an event than Usual Care patients (28% vs. 47%, HR = 0.52, 95% CI: 0.31–0.86). The number needed to treat to prevent one event over five years was 6.1. The likelihood of an event did not differ between IMPACT and Usual Care patients with baseline CVD (86% vs. 81%, HR = 1.19, 95% CI: 0.70–2.03). Conclusions Collaborative depression care delivered before CVD onset halved the excess risk of hard CVD events among older, depressed patients. Our findings raise the possibility that the IMPACT intervention could be used as a CVD primary prevention strategy.

    HMG-CoA reductase inhibitors (statins) are among the most widely used hypolypemizing drugs with a pleiotropic activity. Numerous clinical trials have demonstrated that statins can have a significant effect in the prevention of cardiovascular diseases in the general population. In patients with renal failure, this drug preserves the hypolypemizing efficacy found in the general population without increasing their unwanted side-effects. The re-analysis of data from epidemiological studies conducted on the general population has confirmed that statins provide cardiovascular protection also in subjects with renal failure. These data have been partly confirmed by the findings made by 4D (Die Deutsche Diabetes Dialyse Studie) and Alert studies, conducted on diabetic patients on dialysis and patients with renal transplants, respectively. The results of other studies, such as AURORA, SHARP, REnal and Vascular End stage Disease, and ESPLANADE, clearly indicate that statins prevent cardiovascular disease in patients with renal insufficiency, just as they do in the general population.

    Objective In acute coronary syndrome (ACS) cardiac cell damage is preceded by thrombosis. Therefore, plasma coagulation markers may have additional diagnostic relevance in ACS. By using novel coagulation assays this study aims to gain more insight into the relationship between the coagulation system and ACS. Methods We measured plasma thrombin generation, factor XIa and D-dimer levels in plasma from ACS (n = 104) and non-ACS patients (n = 42). Follow-up measurements (n = 73) were performed at 1 and 6 months. Associations between coagulation markers and recurrent cardiovascular events were calculated by logistic regression analysis. Results Thrombin generation was significantly enhanced in ACS compared to non-ACS patients: peak height 148±53 vs. 122±42 nM. There was a significantly diminished ETP reduction (32 vs. 41%) and increased intrinsic coagulation activation (25 vs. 7%) in ACS compared to non-ACS patients. Furthermore, compared to non-ACS patients factor XIa and D-dimer levels were significantly elevated in ACS patients: 1.9±1.1 vs. 1.4±0.7 pM and 495(310–885) vs. 380(235–540) μg/L. Within the ACS spectrum, ST-elevated myocardial infarction patients had the highest prothrombotic profile. During the acute event, thrombin generation was significantly increased compared to 1 and 6 months afterwards: peak height 145±52 vs. 100±44 vs. 98±33 nM. Both peak height and factor XIa levels on admission predicted recurrent cardiovascular events (OR: 4.9 [95%CI 1.2–20.9] and 4.5 [1.1–18.9]). Conclusion ACS patients had an enhanced prothrombotic profile, demonstrated by an increased thrombin generation potential, factor XIa and D-dimer levels. This study is the first to demonstrate the positive association between factor XIa, thrombin generation and recurrent cardiovascular events. PMID:27419389

    Habitual physical activity and regular exercise training improve cardiovascular health and longevity. A physically active lifestyle is, therefore, a key aspect of primary and secondary prevention strategies. An appropriate volume and intensity are essential to maximally benefit from exercise interventions. This document summarizes available evidence on the relationship between the exercise volume and risk reductions in cardiovascular morbidity and mortality. Furthermore, the risks and benefits of moderate- versus high-intensity exercise interventions are compared. Findings are presented for the general population and cardiac patients eligible for cardiac rehabilitation. Finally, the controversy of excessive volumes of exercise in the athletic population is discussed. PMID:26796398

    Abstract No study has evaluated whether subnormal estimated glomerular filtration rate (eGFR) (between 61 and 90 mL/min) and high normal albumin–creatinine ratio (ACR) (<30 mg/g) are associated with cardiovascular (CV) events and mortality in type 2 diabetic (T2DM) patients with normoalbuminuria. We observed a longitudinal cohort study of 1291 T2DM patients with normoalbuminuria who were receiving intensified multifactorial treatment from 2004 to 2008. Cox regression models were used to evaluate eGFR and ACR as the risk factors of major CV events (nonfatal myocardial infarction and stroke) and mortality. During the 4-year period, 56 patients died and 159 patients developed major CV events. We found eGFR, but not ACR, to be associated with major CV events. Compared to those with eGFR higher than 90 mL/min, patients with subnormal eGFR (HR: 3.133, 1.402–7.002, P = 0.005) were at greater risk of incident major CV events. Extremely low eGFR (<30 mL/min) was associated with mortality only in patients under 65 years old. Subnormal eGFR was a strong predictor of major CV events in diabetic patients with normoalbuminuria. Normoalbuminuric diabetic patients with subnormal eGFR may need intensive CV risk factor intervention to prevent and treat CV events. PMID:26765399

    The association between herpes zoster and cardiovascular complications remains vague with limited study on the association between these two disorders. This study evaluated the risk of cardiovascular diseases in patients with herpes zoster. From insurance claims data of Taiwan, 19,483 patients with herpes zoster diagnosed in 1998-2008 and 77,932 subjects without herpes zoster were identified in this study. Both cohorts were followed up until the end of 2010 to measure the incidence of arrhythmia and coronary artery disease. The incidence rate ratio and adjusted hazard ratio (HR) of the cardiovascular complications with 95% confidence interval (CI) were estimated. The incidence of arrhythmia was 1.17-fold greater in the herpes zoster cohort than in the non-herpes zoster cohort (13.2 vs. 11.3 per 1,000 person-years), with an adjusted HR of 1.16 (P < 0.01). The coronary artery disease incidence in the herpes zoster cohort was 1.16-fold higher than that in the non-herpes zoster cohort (9.02 vs. 7.83 per 1,000 person-years), with an adjusted HR of 1.11 (P < 0.01). Over the stratified follow-up years, adjusted HRs were 1.22 (95% CI = 1.12-1.34) for arrhythmia and 1.14 (95% CI = 1.02-1.28) for coronary artery disease within 2 years after herpes zoster diagnosis. The risk measured for these disorders declined over time. Comorbidities of hypertension, diabetes, and hyperlipidemia also contributed to these cardiovascular disorders with greater extent. It is concluded that the contribution of herpes zoster to the risk of arrhythmia and cardiovascular diseases is less strong than that of hypertension, diabetes, and hyperlipidemia.

    Context There are anecdotal reports of adverse events (AEs) associated with exercise in people with spinal cord injury (SCI) and consequent concern by people with SCI and their providers about potential risks of exercise. Enumeration of specific events has never been performed and the extent of risk of exercise to people with SCI is not understood. Objective To systematically review published evidence to identify and enumerate reports of adverse events or AEs associated with training in persons with SCI. Methods Review was limited to peer-reviewed studies published in English from 1970 to 2011: (1) in adults with SCI, (2) evaluating training protocols consisting of repeated sessions over at least 4 weeks to maintain or improve cardiovascular health, (3) including volitional exercise modalities and functional electrical stimulation (FES)-enhanced exercise modalities, and (4) including a specific statement about AEs. Trained reviewers initially identified a total of 145 studies. After further screening, 38 studies were included in the review. Quality of evidence was evaluated using established procedures. Results There were no serious AEs reported. There were no common AEs reported across most types of interventions, except for musculoskeletal AEs related to FES walking. There were few AEs in volitional exercise studies. Conclusion There is no evidence to suggest that cardiovascular exercise done according to guidelines and established safety precautions is harmful. To improve the strength of these conclusions, future publications should include definition of AEs, information about pre-intervention screening, and statements of the nature and extent of AEs.

    Objectives Despite growing evidence that arterial stiffness has important predictive value for cardiovascular disease in patients with advanced stages of chronic kidney disease, the predictive significance of arterial stiffness in individuals with mildly impaired renal function has not been established. The aim of this study was to evaluate the predictive value of arterial stiffness on cardiovascular disease in this specific population. Materials and methods We analyzed measurements of arterial stiffness (carotid–femoral pulse-wave velocity [cf-PWV]) and the incidence of major adverse cardiovascular events (MACEs) in 1,499 subjects from a 4.8-year longitudinal study. Results A multivariate Cox proportional-hazard regression analysis showed that in individuals with normal renal function (estimated glomerular filtration rate [eGFR] ≥90 mL/min/1.73 m2), the baseline cf-PWV was not associated with occurrence of MACEs (hazard ratio 1.398, 95% confidence interval 0.748–2.613; P=0.293). In individuals with mildly impaired renal function (eGFR <90 mL/min/1.73 m2), a higher baseline cf-PWV level was associated with a higher risk of MACEs (hazard ratio 2.334, 95% confidence interval 1.082–5.036; P=0.031). Conclusion Arterial stiffness is a moderate and independent predictive factor for MACEs in individuals with mildly impaired renal function (eGFR <90 mL/min/1.73 m2). PMID:27621605

    Objectives We aimed to quantify the risk of major adverse cardiovascular events (MACE) among patients with psoriatic arthritis (PsA), rheumatoid arthritis (RA), and psoriasis without known PsA compared to the general population after adjusting for traditional cardiovascular risk factors. Methods A population-based longitudinal cohort study from 1994–2010 was performed in The Health Improvement Network (THIN), a primary care medical record database in the United Kingdom. Patients aged 18–89 with PsA, RA, or psoriasis were included. Up to 10 unexposed controls matched on practice and index date were selected for each patient with PsA. Outcomes included cardiovascular death, myocardial infarction, cerebrovascular accidents, and the composite outcome (MACE). Cox proportional hazards models were used to calculate the hazard ratios (HR) for each outcome adjusted for traditional risk factors. A priori we hypothesized an interaction between disease status and disease modifying anti-rheumatic drug (DMARD) use. Results Patients with PsA (N=8,706), RA (N=41,752), psoriasis (N=138,424) and unexposed controls (N=81,573) were identified. After adjustment for traditional risk factors, the risk of MACE was higher in PsA patients not prescribed a DMARD (HR 1.24, 95%CI: 1.03 to 1.49), patients with RA (No DMARD: HR 1.39, 95%CI: 1.28 to 1.50, DMARD: HR 1.58, 95%CI: 1.46 to 1.70), patients with psoriasis not prescribed a DMARD (HR 1.08, 95%CI: 1.02 to 1.15) and patients with severe psoriasis (DMARD users: HR 1.42, 95%CI: 1.17 to 1.73). Conclusions Cardiovascular risk should be addressed with all patients affected by psoriasis, psoriatic arthritis or rheumatoid arthritis. PMID:25351522

Within-person differences were used to estimate CV-related outcomes. Setting Patients in the UK who had their first CV event between January 2006 and March 2012. Participants Patients ≥18 years who had a CV event and received at least 2 lipid-modifying therapy prescriptions within 180 days beforehand. Primary and secondary outcome measures Direct medical costs (2014 £) were estimated in 3 periods: baseline (pre-event), acute (6 months afterwards) and long-term (subsequent 30 months). Primary outcomes included incremental costs, resource usage and total costs per period. Results There were 24 093 patients in the first event cohort of whom 5274 were included in the second event cohort. The mean incremental acute CV event costs for the first event and second event cohorts were: coronary artery bypass graft/percutaneous transluminal coronary angioplasty (CABG/PTCA) £5635 and £5823, myocardial infarction £4275 and £4301, ischaemic stroke £3512 and £4572, heart failure £2444 and £3461, unstable angina £2179 and £2489 and transient ischaemic attack £1537 and £1814. The mean incremental long-term costs were: heart failure £848 and £2829, myocardial infarction £922 and £1385, ischaemic stroke £973 and £682, transient ischaemic attack £705 and £1692, unstable angina £328 and £677, and CABG/PTCA £−368 and £599. Hospitalisation accounted for 95% of acute and 61% of long-term incremental costs. Higher comorbidity was associated with higher long-term costs. Conclusions Revascularisation and myocardial infarction were associated with the highest incremental costs following

    Objectives To evaluate (1) the inter-individual variability of reductions in low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C) or apolipoprotein B (apoB) levels achieved with statin therapy, (2) the proportion of patients not reaching guideline-recommended lipid levels on high-dose statin therapy, and (3) the association between very low levels of atherogenic lipoproteins achieved with statin therapy and CVD risk. Background Levels of atherogenic lipoproteins achieved with statin therapy are highly variable, but the consequence of this variability for cardiovascular disease (CVD) risk is not well documented. Methods Meta-analysis of individual patient data from 8 randomized controlled statin trials in which conventional lipids and apolipoproteins were determined in all study participants at baseline and at 1-year follow-up. Results Among 38,153 patients allocated to statin therapy, a total of 6,286 major cardiovascular events occurred in 5,387 study participants during follow-up. There was large inter-individual variability in the reductions of LDL-C, non-HDL-C and apoB achieved with a fixed statin dose. Over 40% of trial participants assigned to high-dose statin therapy did not reach an LDL-C target below 70 mg/dL. Compared to patients who achieved an LDL-C > 175 mg/dL, those who reached an LDL-C 75-100 mg/dL, 50-75 mg/dL and < 50 mg/dL had adjusted hazard ratios for major cardiovascular events of 0.56 (95%CI 0.46-0.67), 0.51 (95%CI 0.42-0,62) and 0.44 (95%CI 0.35-0.55), respectively. Similar associations were observed for non-HDL-C and apoB. Conclusions The reduction of LDL-C, non-HDL-C and apoB levels achieved with statin therapy displays large inter-individual variation. Among trial participants treated with high-dose statin therapy, over 40% do not reach an LDL-C target <70 mg/dL. Patients who achieve very low LDL-C levels have a lower risk of major cardiovascular events than those achieving moderately low levels

    Long thought to be two separate syndromes, Ehlers-Danlos syndrome hypermobility type (EDS-HT) and benign joint hypermobility syndrome (BJHS) appear on close examination to represent the same syndrome, with virtually identical clinical manifestations. While both EDS-HT and BJHS were long thought to lack the genetic loci of other connective tissue disorders, including all other types of EDS, researchers have discovered a genetic locus that accounts for manifestations of both EDS-HT and BJHS in a small population of patients. However, given the modest sample size of these studies and the strong correlation between serum levels of tenascin-X with clinical symptoms of both EDS-HT and BJHS, strong evidence exists for the origins of both types of hypermobility originating in haploinsufficiency or deficiency of the gene TNXB, responsible for tenascin-X. Tenascin-X regulates both the structure and stability of elastic fibers and organizes collagen fibrils in the extra-cellular matrix (ECM), impacting the rigidity or elasticity of virtually every cell in the body. While the impacts of tenascin-X insufficiency or deficiency on the skin and joints have received some attention, its potential cardiovascular impacts remain relatively unexplored. Here we set forth two novel hypotheses. First, TNXB haploinsufficiency or deficiency causes the range of clinical manifestations long identified with both EDS-HT and BJHS. And, second, that haploinsufficiency or deficiency of TNXB may provide some benefits against adverse cardiovascular events, including heart attack and stroke, by lowering levels of arterial stiffness associated with aging, as well as by enhancing accommodation of accrued atherosclerotic plaques. This two-fold hypothesis provides insights into the mechanisms underlying the syndromes previous identified with joint hypermobility, at the same time the hypothesis also sheds light on the role of the composition of the extracellular matrix and its impacts on endothelial sheer

    Increasing evidence connects non-alcoholic fatty liver disease (NAFLD) to cardiovascular disease (CVD). The aim of this study is to assess whether and to what extent the excess risk of CVD is conferred by NAFLD in a meta-analysis. We systematically searched PubMed, EmBase, Web of Science, and Cochrane Library for reports published between 1965 and July 3, 2015. Studies that reported data on association between NAFLD and adverse cardiovascular events or mortality were included. Thirty-four studies (164,494 participants, 21 cross-sectional studies, and 13 cohort studies) were included. NAFLD was not associated with overall mortality (HR = 1.14, 95% CI: 0.99-1.32) and CVD mortality (HR = 1.10, 95% CI: 0.86-1.41). However, NAFLD was associated with an increased risk of prevalent (OR = 1.81, 95% CI: 1.23-2.66) and incident (HR = 1.37, 95% CI: 1.10-1.72) CVD. For some specific CVDs, NAFLD was associated with an increased risk of prevalent (OR = 1.87, 95% CI: 1.47-2.37) and incident (HR = 2.31, 95% CI: 1.46-3.65) coronary artery disease (CAD), prevalent (OR = 1.24, 95% CI: 1.14-1.36) and incident (HR = 1.16, 95% CI: 1.06-1.27) hypertension, and prevalent (OR = 1.32, 95% CI: 1.07-1.62) atherosclerosis. In conclusion, the presence of NAFLD is associated with an increased risk of major adverse cardiovascular events, although it is not related to mortality from all causes or CVD. PMID:27633274

    Background The systematic use of aspirin and statins in patients with diabetes and no previous cardiovascular events is controversial. We sought to assess the effects of aspirin and statins on the thrombotic risk assessed by thrombin generation (TG) among patients with type II diabetes mellitus and no previous cardiovascular events. Methodology/Principal Findings Prospective, randomized, open, blinded to events evaluation, controlled, 2×2 factorial clinical trial including 30 patients randomly allocated to aspirin 100 mg/d, atorvastatin 40 mg/d, both or none. Outcome measurements included changes in TG levels after treatment (8 to 10 weeks), assessed by a calibrated automated thrombogram. At baseline all groups had similar clinical and biochemical profiles, including TG levels. There was no interaction between aspirin and atorvastatin. Atorvastatin significantly reduced TG measured as peak TG with saline (85.09±55.34 nmol vs 153.26±75.55 nmol for atorvastatin and control groups, respectively; p = 0.018). On the other hand, aspirin had no effect on TG (121.51±81.83 nmol vs 116.85±67.66 nmol, for aspirin and control groups, respectively; p = 0.716). The effects of treatments on measurements of TG using other agonists were consistent. Conclusions/Significance While waiting for data from ongoing large clinical randomized trials to definitively outline the role of aspirin in primary prevention, our study shows that among diabetic patients without previous vascular events, statins but not aspirin reduce thrombotic risk assessed by TG.

    Background/Aims: The CHADS2 score, used to predict the risk of ischemic stroke in atrial fibrillation (AF) patients, has been reported recently to predict ischemic stroke in patients with coronary heart disease, regardless of the presence of AF. However, little data are available regarding the relationship between the CHADS2 score and cardiovascular outcomes. Methods: This was a retrospective study on 104 patients admitted for acute coronary syndrome (ACS) who underwent coronary angiography, carotid ultrasound, and transthoracic echocardiography. Results: The mean age of the subjects was 60.1 ± 12.6 years. The CHADS2 score was as follows: 0 in 46 patients (44.2%), 1 in 31 (29.8%), 2 in 18 (17.3%), and ≥ 3 in 9 patients (8.7%). The left atrial volume index (LAVi) showed a positive correlation with the CHADS2 score (20.8 ± 5.9 for 0; 23.2 ± 6.7 for 1; 26.6 ± 10.8 for 2; and 30.3 ± 8.3 mL/m2 for ≥3; p = 0.001). The average carotid total plaque area was significantly increased with CHADS2 scores ≥ 2 (4.97 ± 7.17 mm2 vs. 15.52 ± 14.61 mm2; p = 0.002). Eight patients experienced cardiovascular or cerebrovascular (CCV) events during a mean evaluation period of 662 days. A CHADS2 score ≥ 3 was related to an increase in the risk of CCV events (hazard ratio, 14.31; 95% confidence interval, 3.53 to 58.06). Furthermore, LAVi and the severity of coronary artery obstructive disease were also associated with an increased risk of CCV events. Conclusions: The CHADS2 score may be a useful prognostic tool for predicting CCV events in ACS patients with documented coronary artery disease. PMID:26767860

    Background Moderately increased albuminuria (formerly called microalbuminuria) is widely recognized as a predictor of cardiovascular disease. However, it is not clear whether this observation is applicable to the Asian population, as studies leading to this conclusion were conducted on Western populations. The aim of this study was to examine the hypothesis if moderately increased albuminuria could be an independent predictor of cardiovascular mortality and morbidity in the Japanese population. Methods and Results The study population consisted of 3093 inhabitants of Watari, Miyagi Prefecture, who participated in an annual health check-up in 2009. We examined anthropometry, sitting blood pressure, fasting blood sample, and urine albumin-to-creatinine ratio (UACR). After baseline assessment, subjects were followed prospectively for up to 60 months. The incidence of major cardiovascular events (stroke, myocardial infarction, revascularization, and cardiovascular death) was determined based on death certificate records or medical claims sent to the National Health Insurance of Japan. Follow-up was discontinued for those who reached 75 years of age because they were moved to a different medical insurance system. We observed 57 cardiovascular events during a mean follow-up period of 47.8 months. The cumulative incidence rate for major cardiovascular events was significantly higher in patients with moderately increased albuminuria (UACR 30–299 mg/gCr) than in those with normoalbuminuria (UACR <30 mg/gCr) (6.4% vs. 2.2%, p = 0.0002 by log-rank test). Multivariate Cox proportional hazards analyses have revealed that moderately increased albuminuria is an independent predictor of cardiovascular events (HR 2.386, 95% CI: 1.120–4.390). Conclusions Moderately increased albuminuria is an independent predictor of cardiovascular events in the general Japanese population under 75 years of age. PMID:25849735

    Ten years ago, just weeks after the September 11 attacks, the United States experienced a deliberate act of bioterrorism. Through use of the postal service, anthrax spores were widely disseminated, including to homes, the Senate, and major newsrooms, resulting in morbidity and mortality and effectively disrupting our way of life and revealing our vulnerability. Even though such attacks had been the subject of much writing and had been planned for, detection of and the appropriate response to an attack with an agent from the so-called "Category 'A' List" had only been considered in theoretical terms. What transpired during the following difficult weeks, including how public health and federal government agencies performed, has been both praised and criticized. An intertwined epidemiologic and criminal investigation of such magnitude was unprecedented in U.S. history. To address the question of whether we as a nation are now better prepared for future threats involving biologic agents, it is important to learn from the lessons of the 2001 anthrax attacks, including the critical role of clinicians in surveillance. As physicians involved in diagnosing anthrax in the index case and alerting authorities, we offer our perspective on these events a decade after their occurrence. PMID:21969275

    Objectives: Long-acting bronchodilators are mainstay treatment for moderate to severe chronic obstructive pulmonary disease. A growing body of evidence indicates an increased risk of cardiovascular events upon initiation of these medications. We hypothesize that this risk is higher in patients with chronic obstructive pulmonary disease who had a preexisting cardiovascular disease regardless of receipt of any cardiovascular medication. Methods: A retrospective cohort of patients with a diagnosis of chronic obstructive pulmonary disease based on two outpatient visits or one inpatient visit for chronic obstructive pulmonary disease (International Classification of Diseases, 9th Edition, Clinical Modification codes 491.x, 492.x, 496) in any year between 2001 and 2012 from a commercial insurance database. We then selected those initiating long-acting bronchodilator treatments between April 2001 and September 2012. Each patient had a 1 year look back period to determine history of cardiovascular disease or cardiovascular disease treatment from the time of first prescription of long-acting beta agonist, long-acting muscarinic antagonist, or long-acting beta agonist combined with inhaled corticosteroids. Patients were followed for 90 days for hospitalizations or emergency department visits for cardiovascular event. The cohort was divided into four groups based on the presence of cardiovascular disease (including ischemic heart disease, hypertension, ischemic stroke, heart failure, tachyarrhythmias and artery disease based on International Classification of Diseases, 9th Edition, Clinical Modification codes) and cardiovascular disease treatment defined as acetylsalicylic acid, beta blockers, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, antiplatelet, anticoagulants, calcium channel blockers, nitrate, digoxin, diuretics, antiarrhythmics or statins. Odds of emergency department visit or hospitalization in the 90 days after prescription were

    Monocytes and dendritic cells (DC) produce tumour necrosis factor (TNF)α during inflammatory processes, but secrete interleukin (IL)-10 simultaneously in order to balance the pro-inflammation. In the present study, we investigated the expression of TNFα and IL-10 by monocytes and DC in patients with a poor cardiovascular prognosis after 10 years. Peripheral blood monocytes were isolated from 30 patients with coronary artery disease (CAD) with stable angina pectoris (SAP), or with an acute coronary syndrome (ACS). Monocytes were differentiated over 7 days to DC. Intracellular accumulation of TNFα and IL-10 in monocytes and DC was analysed by flow cytometry and correlated with the heart function, total and cardiovascular (CV) mortality, as well as with cardiovascular event rate over 10 years. We observed a decreased left ventricular function (LV-EF) for both SAP and ACS patients (p<0.01), as well as a reduced IL-10/TNFα ratio for monocytes (p=0.01) and DC (p<0.01) for both patient groups in comparison to age-matched control group. Only the IL-10/TNFα ratio for monocytes correlated with LV-EF (r=0.4302; p<0.01). Patients with a low LV-EF as well as patients with a low IL-10/TNFα ratio showed an increased cardiovascular mortality over 10 years (both p<0.05). The IL-10/TNFα ratio is decreased in patients with low ejection fraction and poor prognosis. The reduced heart function correlates with an increased proinflammatory state (low monocytic IL-10/TNFα ratio) in patients with CAD. This observed imbalance of IL-10 and TNFα in monocytes might explain pathophysiological processes in atherosclerosis and heart failure. PMID:25384561

    We reviewed available evidence for cardiovascular effects of n-3 polyunsaturated fatty acid (PUFA) consumption, focusing on long chain (seafood) n-3 PUFA, including their principal dietary sources, effects on physiological risk factors, potential molecular pathways and bioactive metabolites, effects on specific clinical endpoints, and existing dietary guidelines. Major dietary sources include fatty fish and other seafood. n-3 PUFA consumption lowers plasma triglycerides, resting heart rate, and blood pressure and might also improve myocardial filling and efficiency, lower inflammation, and improve vascular function. Experimental studies demonstrate direct anti-arrhythmic effects, which have been challenging to document in humans. n-3 PUFA affect a myriad of molecular pathways, including alteration of physical and chemical properties of cellular membranes, direct interaction with and modulation of membrane channels and proteins, regulation of gene expression via nuclear receptors and transcription factors, changes in eicosanoid profiles, and conversion of n-3 PUFA to bioactive metabolites. In prospective observational studies and adequately powered randomized clinical trials, benefits of n-3 PUFA seem most consistent for coronary heart disease mortality and sudden cardiac death. Potential effects on other cardiovascular outcomes are less-well-established, including conflicting evidence from observational studies and/or randomized trials for effects on nonfatal myocardial infarction, ischemic stroke, atrial fibrillation, recurrent ventricular arrhythmias, and heart failure. Research gaps include the relative importance of different physiological and molecular mechanisms, precise dose-responses of physiological and clinical effects, whether fish oil provides all the benefits of fish consumption, and clinical effects of plant-derived n-3 PUFA. Overall, current data provide strong concordant evidence that n-3 PUFA are bioactive compounds that reduce risk of cardiac

    Few data exist on whether healthy lifestyle factors are associated with better prognosis among individuals with apparent treatment-resistant hypertension, a high-risk phenotype of hypertension. The purpose of this study was to assess the association of healthy lifestyle factors with cardiovascular events, all-cause mortality, and cardiovascular mortality among individuals with apparent treatment-resistant hypertension. We studied participants (n=2043) from the population-based Reasons for Geographic and Racial Differences in Stroke (REGARDS) study with apparent treatment-resistant hypertension (blood pressure ≥140/90 mm Hg despite the use of 3 antihypertensive medication classes or the use of ≥4 classes of antihypertensive medication regardless of blood pressure control). Six healthy lifestyle factors adapted from guidelines for the management of hypertension (normal waist circumference, physical activity ≥4 times/week, nonsmoking, moderate alcohol consumption, high Dietary Approaches to Stop Hypertension diet score, and low sodium-to-potassium intake ratio) were examined. A greater number of healthy lifestyle factors were associated with lower risk for cardiovascular events (n=360) during a mean follow-up of 4.5 years. Multivariable-adjusted hazard ratios [HR (95% confidence interval)] for cardiovascular events comparing individuals with 2, 3, and 4 to 6 versus 0 to 1 healthy lifestyle factors were 0.91 (0.68-1.21), 0.80 (0.57-1.14), and 0.63 (0.41-0.95), respectively (P-trend=0.020). Physical activity and nonsmoking were individual healthy lifestyle factors significantly associated with lower risk for cardiovascular events. Similar associations were observed between healthy lifestyle factors and risk for all-cause and cardiovascular mortality. In conclusion, healthy lifestyle factors, particularly physical activity and nonsmoking, are associated with a lower risk for cardiovascular events and mortality among individuals with apparent treatment

    Some vitamins and minerals play an important role in the secondary prevention of cardiovascular diseases (CVD). The aim of this study was the assessment of dietary vitamins and minerals intake and patterns of supplement use among subjects with diagnosed CVD in Polish population. Within the frame of the WOBASZ study, a representative sample of whole Polish population aged 20-74 (7257 subjects) was screened in 2003-2005. A subsample of 803 persons with a clinical history of cardiovascular events was analyzed. It was found, that the average diet of adult Polish citizens with established CVD was not balanced concerning the intake of vitamins and minerals. Daily intake of antioxidant vitamins (A, C and E) and vitamin B12 was satisfactory the realization degree of recommended dietary allowances (RDA) was about 126-310%. The insufficient amounts of vitamins B1, B2, folates, as well as potassium, calcium, magnesium in diet of both genders and vitamin B6 in men and iron in women were noted. The highest deficiency has been noticed in vitamins B1, B2 and calcium and magnesium intake--the realization degree of RDA has stayed on 54-82% level. Around 1% of potassium, calcium and magnesium intake in both genders and more than 25% of vitamins E and B6 consumption in women derived from the supplementation.

    Serum c-reactive protein (CRP) was suggested for the assessment of intermediate cardiovascular (CV) risk. Here, systemic or intraplaque CRP levels were investigated as predictors of major adverse cardiovascular events (MACEs) in patients with severe carotid stenosis. CRP levels were assessed in the serum and within different portions (upstream and downstream) of carotid plaques of 217 patients undergoing endarterectomy. The association between CRP and intraplaque lipids, collagen, neutrophils, smooth muscle cells (SMC), and macrophage subsets was determined. No correlation between serum CRP and intraplaque biomarkers was observed. In upstream portions, CRP content was directly correlated with intraplaque neutrophils, total macrophages, and M1 macrophages and inversely correlated with SMC content. In downstream portions, intraplaque CRP correlated with M1 and M2 macrophages. According to the cut-off point (CRP > 2.9%) identified by ROC analysis in upstream portions, Kaplan-Meier analysis showed that patients with high CRP levels had a greater rate of MACEs. This risk of MACEs increased independently of age, male gender, serum CRP, and statin use. In conclusion, in patients with severe carotid artery stenosis, high CRP levels within upstream portions of carotid plaques directly and positively correlate with intraplaque inflammatory cells and predict MACEs at an 18-month follow-up period.

    Advanced stages of both cancer and atherosclerosis are characterized by a local increase in tissue mass that may be hard to control. This increase in tissue mass can be attributed to oxidation-sensitive modification of cell cycle-related events, including cellular proliferation, differentiation, and apoptosis, which could be secondary to alteration in the activity of tumor suppressor gene and oncogene products. The oncogene c-Myc has classically been considered to be involved in carcinogenesis and has more recently been implicated in both endothelial dysfunction and atherogenesis as well. Consequently, inhibition of c-Myc-dependent signaling has become a novel therapeutic opportunity and challenge in atherosclerosis and other cardiovascular diseases. Antioxidant strategies, RNA synthesis inhibitors such as mithramycin, and gene therapeutic approaches with antisense oligonucleotides against c-Myc are some of the promising strategies. In general, the increased biologic understanding of the participation of cell cycle events and targeting these events may enable to attenuate or prevent some of the complications of vascular and neoplastic diseases.

    Red blood cell distribution width (RDW) is a robust marker of adverse clinical outcomes in various populations. However, the clinical significance of a progressive rise in RDW is undetermined in end-stage renal disease (ESRD) patients. The purpose of this study was to determine the prognostic importance of a change in RDW in ESRD patients. Three hundred twenty-six incident dialysis patients were retrospectively analyzed. Temporal changes in RDW during 12 months after dialysis initiation were assessed by calculating the coefficients by linear regression. Patients were divided into two groups: an RDW-decreased group who had negative coefficient values (n = 177) and an RDW-increased group who had positive values (n = 149). The associations between rising RDW and mortality and cardiovascular (CV) events were investigated. During a median follow-up of 2.7 years (range, 1.0-7.7 years), 75 deaths (24.0%) and 60 non-fatal CV events (18.4%) occurred. The event-free survival rate for the composite of end-points was lower in the RDW-increased group (P = 0.004). After categorizing patients according to baseline RDW, the event-free survival rate was lowest in patients with a baseline RDW >14.9% and increased RDW, and highest in patients with a baseline RDW ≤14.9% and decreased RDW (P = 0.02). In multivariate analysis, rising RDW was independently associated with the composite of end-points (hazard ratio = 1.75, P = 0.007), whereas the baseline RDW was not. This study shows that a progressive rise in RDW independently predicted mortality and CV events in ESRD patients. Rising RDW could be an additive predictor for adverse CV outcomes ESRD patients.

    HDL composition rather than HDL-cholesterol (HDL-C) levels seems to be a key determinant of HDL-induced atheroprotection. Heterozygous familial hypercholesterolemia (FH) patients, with lifelong exposure to high LDL levels, show a high prevalence of premature coronary artery disease. We hypothesized that HDL of FH patients might have a modified protein composition and investigated the proteomic signature of HDL obtained from FH patients and their unaffected relatives. HDLs were characterized by 2D electrophoresis/MS in 10 families from the SAFEHEART cohort (3 individuals/family: 2 with genetic FH diagnosis and 1 non-FH relative) clinically characterized and treated as per guidelines. FH patients had lower apoA-I levels and a differential HDL distribution profile of apoL1 and apoA-IV. ELISA validation revealed decreased apoL1 serum levels in FH patients. ApoL1 levels were able to predict presentation of an ischemic cardiac event, and apoL1/HDL-C ratio was associated with the survival rate after the event. FH patients who died because of a fatal cardiac event had lower apoL1 and LCAT content in HDL3 an average of 3.5 years before the event than those who survived. Changes in HDL protein composition could affect patients' prognosis. The proteomic profile of apoL1 is modified in HDLs of high cardiovascular risk patients, and apoL1 plasma levels are significantly lower in serum and in HDL3 of patients that will suffer an adverse cardiac event within 3 years.

    This study aimed to clarify the effects of acute exercise and cardiovascular fitness on cognitive function using the Stroop test and event-related desynchronization (ERD) in an aged population. Old adults (63.10 ± 2.89 years) were first assigned to either a high-fitness or a low-fitness group, and they were then subjected to an acute exercise treatment and a reading control treatment in a counterbalanced order. Alpha ERD was recorded during the Stroop test, which was administered after both treatments. Acute exercise improved cognitive performance regardless of the level of cognition, and old adults with higher fitness levels received greater benefits from acute exercise. Additionally, acute exercise, rather than overall fitness, elicited greater lower and upper alpha ERDs relative to the control condition. These findings indirectly suggest that the beneficial effects of acute exercise on cognitive performance may result from exercise-induced attentional control observed during frontal neural excitation.

    This article reviews the relationship between serum lipids and cardiovascular disease (CVD) in hemodialysis patients. Epidemiologic studies showed a cholesterol paradox in hemodialysis patients, but it can be solved by taking protein-energy wasting and inflammation into consideration. Wasting and inflammation are the risk factors of fatality after incident CVD. Randomized controlled trials showed neutral effects of statins and statin-ezetimibe combination on CVD outcomes in dialysis patients. Current guidelines in Japan recommend that low-density lipoprotein cholesterol (LDL-C) be <120 mg/dL, or non-high-density lipoprotein cholesterol (non-HDL-C) be <150 mg/dL as an alternative target in patients with chronic kidney disease (CKD), whereas Kidney Disease: Improving Global Outcome (KDIGO) guidelines do not recommend any target lipid levels. In addition to "treat to target" and "fire and forget" guidelines, it is possible to recommend that lipid-lowering medication be initiated in certain subgroups of CKD patients. New directions of lipid research in CKD include cholesterol metabolism markers, omega-3 polyunsaturated fatty acids, and modifications of lipoproteins. PMID:24072417

    Microalbuminuria is associated with an increased risk of cardiovascular disease (CVD), but not all individuals require treatment. Retinal microvascular abnormalities and microalbuminuria reflect early systemic microvascular changes. We examined the joint effect of retinal abnormalities and microalbuminuria on CVD risk in an Asian cohort. We conducted a prospective, population-based study. Retinal abnormalities were defined as presence of retinopathy and/or retinal venular widening. Microalbuminuria was defined as urinary albumin: creatinine ratio between 30–300 mg/g. Incident CVD was defined as newly diagnosed clinical stroke, acute myocardial infarction or CVD death. Cox regression models were performed to determine the associations between retinal abnormalities and microalbuminuria with risk of CVD, while controlling for established risk factors. 3,496 participants (aged ≥ 40) were free of prevalent CVD. During the follow-up (5.8 years), 126 (3.60%) participants developed CVD. Persons presenting with both retinal abnormalities and microalbuminuria were 6.71 times (95% CI, 2.68, 16.79) as likely to have incident CVD compared with those without either abnormalities. There was a significant interaction effect between retinal abnormalities and microalbuminuria on incident CVD. Assessment of retinal abnormalities in patients with microalbuminuria may provide additional value in identifying persons at risk of developing CVD. PMID:27273133

    The PreFord Study is a multicenter prospective cohort study to evaluate guideline based risk management on primary prevention of cardiovascular diseases. Furthermore a randomised controlled trial (RCT) will be designed to analyse the effect of a special intervention program. 40,000 employees of the Ford Motor Company, Visteon Company and Deutz Company in Germany will be included, monitored for ten years and the following primary endpoints will be investigated: 1. evaluation and comparison of established and newly developed risk-scores, 2. the relative impact of single and combined cardiovascular risk factors on cardiovascular diseases, 3. the influence of a novel occupationally integrated ambulant rehabilitation program in combination with a guideline oriented optimal drug therapy within a high risk group on the primary endpoint: risk reduction by, 4. the influence of this intervention on secondary endpoints: death, myocardial infarction and stroke, combined appearance of angina pectoris and hospitalisation, occurrence of cerebral circulatory disorder and hospitalisation, occurrence of peripheral occlusive arterial disease and hospitalisation and single cardiovascular risk factors and cost-benefit-analysis. Beginning with an cross sectional study there will be a systemic screening of cardiovascular risk profiles, of anthropometric data and different lifestyle-factors. Based on these data participants will be differentiated into three risk-groups according to the risk score of the European Society of Cardiology (risk of a lethal primary acute cardiovascular event: I < or = 1%; II > 1-< 5% and III > or = 5%). In the following longitudinal study different strategies will be applied: Group I: low risk (< 0.5% per year): repetition of the investigation after five and ten years.

    Background Few studies have examined the impact of lifecourse socioeconomic position (SEP) on cardiovascular disease (CVD) risk among African Americans. Methods and Results We used data from the Jackson Heart Study (JHS) to examine the associations of multiple measures of lifecourse SEP with CVD events in a large cohort of African Americans. During a median of 7.2-year follow-up, 362 new or recurrent CVD events occurred in a sample of 5301 participants aged 21 to 94. Childhood SEP was assessed by using mother’s education, parental home ownership, and childhood amenities. Adult SEP was assessed by using education, income, wealth, and public assistance. Adult SEP was more consistently associated with CVD risk in women than in men: age-adjusted hazard ratios for low versus high income (95% CIs), 2.46 (1.19 to 5.09) in women and 1.50 (0.87 to 2.58) in men, P for interaction=0.1244, and hazard ratio for low versus high wealth, 2.14 (1.39 to 3.29) in women and 1.06 (0.62 to 1.81) in men, P for interaction=0.0224. After simultaneous adjustment for all adult SEP measures, wealth remained a significant predictor of CVD events in women (HR=1.73 [1.04, 2.85] for low versus high). Education and public assistance were less consistently associated with CVD. Adult SEP was a stronger predictor of CVD events in younger than in older participants (HR for high versus low summary adult SEP score 3.28 [1.43, 7.53] for participants ≤50 years, and 1.90 (1.36 to 2.66) for participants >50 years, P for interaction 0.0846). Childhood SEP was not associated with CVD risk in women or men. Conclusions Adult SEP is an important predictor of CVD events in African American women and in younger African Americans. Childhood SEP was not associated with CVD events in this population. PMID:26019130

  1. Potential role of differential medication use in explaining excess risk of cardiovascular events and death associated with chronic kidney disease: A cohort study

    2011-01-01

    Background Patients with chronic kidney disease (CKD) are less likely to receive cardiovascular medications. It is unclear whether differential cardiovascular drug use explains, in part, the excess risk of cardiovascular events and death in patients with CKD and coronary heart disease (CHD). Methods The ADVANCE Study enrolled patients with new onset CHD (2001-2003) who did (N = 159) or did not have (N = 1088) CKD at entry. The MDRD equation was used to estimate glomerular filtration rate (eGFR) using calibrated serum creatinine measurements. Patient characteristics, medication use, cardiovascular events and death were ascertained from self-report and health plan electronic databases through December 2008. Results Post-CHD event ACE inhibitor use was lower (medication possession ratio 0.50 vs. 0.58, P = 0.03) and calcium channel blocker use higher (0.47 vs. 0.38, P = 0.06) in CKD vs. non-CKD patients, respectively. Incidence of cardiovascular events and death was higher in CKD vs. non-CKD patients (13.9 vs. 11.5 per 100 person-years, P < 0.001, respectively). After adjustment for patient characteristics, the rate of cardiovascular events and death was increased for eGFR 45-59 ml/min/1.73 m2 (hazard ratio [HR] 1.47, 95% CI: 1.10 to 2.02) and eGFR < 45 ml/min/1.73 m2 (HR 1.58, 95% CI: 1.00 to 2.50). After further adjustment for statins, β-blocker, calcium channel blocker, ACE inhibitor/ARB use, the association was no longer significant for eGFR 45-59 ml/min/1.73 m2 (HR 0.82, 95% CI: 0.25 to 2.66) or for eGFR < 45 ml/min/1.73 m2 (HR 1.19, 95% CI: 0.25 to 5.58). Conclusions In adults with CHD, differential use of cardiovascular medications may contribute to the higher risk of cardiovascular events and death in patients with CKD. PMID:21917174

    The use of preventive medications in people at high risk of cardiovascular disease is conceptually straightforward, yet in practice the adoption of such measures is disappointingly low, plus there is wide international variation in preventive therapies. Several barriers might explain this shortfall and variation, but the simplicity and economy of a polypill-based strategy might overcome some barriers. The 'Use of a Multidrug Pill In Reducing cardiovascular Events' (UMPIRE) trial assesses whether a polypill strategy (by combining aspirin, a statin and two blood pressure lowering agents) would improve adherence to guideline-indicated therapies and would lower both blood pressure and cholesterol, in people with established cardiovascular disease. UMPIRE, running in India and three European countries (England, Ireland and the Netherlands), is an open, randomised, controlled trial designed to include 1000 participants in India and 1000 in Europe, with a followup of 12-24 months. Participants were randomised to one of two versions of the polypill or relegated to usual care. The primary study outcomes were the self-reported use of aspirin, a statin and at least two blood pressure lowering agents; as well as changes in blood pressure and cholesterol. Secondary outcomes included: any cardiovascular events, reasons for stopping medications, serious adverse events and perceived changes in quality of life. Interpretation of the study data will be enhanced by health, economic and process-related evaluations. UMPIRE is registered with the European Clinical Trials database, as EudraCT: 2009-016278-34 and the Clinical Trials Registry, India as CTRI/2010/091/000250. The trial was part of the 'Single Pill Against Cardiovascular Events (SPACE)' collaboration, which encompasses the 'IMProving Adherence using Combination Therapy (IMPACT)' and 'Kanyini Guidelines Adherence with the Polypill (Kanyini-GAP)' trials.

    The most commonly occurring atherosclerotic manifestations are peripheral artery diseases (PAD). Immune-mediated processes contribute to the development of atherosclerosis, and affect the diseases outcome. The aim of the present study was to assess various immune-competent cells, cytokines and chemokines in patients with PAD and to evaluate whether the base immunological values reflect the subsequent development of cardio/cerebrovascular symptoms. One hundred sixty patients with PAD were followed-up for 42 months. At the time of enrolment, we determined blood lymphocyte subpopulations, both T-helper (Th)1/Th2-type intracytoplasmic cytokines and soluble cytokines, chemokines. Intracellular cytokines were measured on phorbol-myristate-acetate- and ionomycine- stimulated cells. Lymphocyte subgroups were quantified by flow cytometry, soluble cytokines by ELISA and intracellular cytokine levels were measured by flow cytometry. The ankle-brachial index (ABI), indicator of atherosclerosis, was also evaluated. The clinical results were correlated with the immune-parameters to assess the input of immune-inflammatory events in the propagation of vascular manifestation. CD4(+) T-cell proportions in patients with PAD with cerebro- cardio-vascular manifestations were decreased, which further reduced in patients with fatal outcome. Of circulating chemokines, IL-8 (CXCL-8) was increased in patients with subsequent cerebro- cardio-vascular manifestations, compared to those without the symptoms, and further raised in patients with fatal outcome. The percentage of interferon (IFN)-gamma positive cells showed clear negative correlation with ABI. We conclude that altered peripheral lymphocyte subsets and cytokine/chemokine imbalance play important roles in the proinflammatory cascade and reflect disease severity in patients with PAD.

    Results from prevention trials, including the Alzheimer's Disease Anti-inflammatory Prevention Trial (ADAPT), have fueled discussion about the cardiovascular (CV) risks associated with non-steroidal anti-inflammatory drugs (NSAIDs). We tested the hypotheses that (i) adverse CV events reported among ADAPT participants (aged 70 years and older) are associated with increased ratio of urine 11-dehydrothromboxane B(2) (Tx-M) to 2'3-donor-6-keto-PGF1 (PGI-M) attributable to NSAID treatments; (ii) coincident use of aspirin (ASA) would attenuate NSAID-induced changes in Tx-M/PGI-M ratio; and (iii) use of NSAIDs and/or ASA would not alter urine or plasma concentrations of F(2)-isoprostanes (IsoPs), in vivo biomarkers of free radical damage. We quantified urine Tx-M and PGI-M, and urine and plasma F(2)-IsoPs from 315 ADAPT participants using stable isotope dilution assays with gas chromatography/mass spectrometry, and analyzed these data by randomized drug assignment and self-report compliance as well as ASA use. Adverse CV events were significantly associated with higher urine Tx-M/PGI-M ratio, which seemed to derive mainly from lowered PGI-M. Participants taking ASA alone had reduced urine Tx-M/PGI-M compared to no ASA or NSAID; however, participants taking NSAIDs plus ASA did not have reduced urine Tx-M/PGI-M ratio compared to NSAIDs alone. Neither NSAID nor ASA use altered plasma or urine F(2)-IsoPs. These data suggest a possible mechanism for the increased risk of CV events reported in ADAPT participants assigned to NSAIDs, and suggest that the changes in the Tx-M/PGI-M ratio was not substantively mitigated by coincident use of ASA in individuals 70 years or older.

    Venous and arterial thromboses have traditionally been considered distinct pathophysiologic entities. However, the two disorders have many features in common, and there is evidence that persons with venous thrombosis may be at greater risk for arterial events. The pathogenesis of both disorders includes endothelial injury, platelet activation, elevated levels of intrinsic clotting factors and inflammatory markers, increased fibrinogen, and impaired fibrinolysis. In addition, older age, obesity, dyslipidemia, and smoking predispose to both venous and arterial thrombosis. While the evidence that arterial disease is a risk factor for venous thrombosis is inconclusive, arterial disease does appear to occur with a modestly increased frequency in patients with a history of venous thromboembolism. Reported odds ratios in such patients were 1.2 for myocardial infarction, 1.3 for stroke, 2.3 for carotid plaque, and 4.3 for coronary calcification. Of note, in persons under age 40 with unprovoked venous thrombosis, the odds ratio for acute myocardial infarction was as high as 3.9. In general, however, venous disease is considered to be a weak risk factor for arterial thrombosis, and the use of agents specifically targeted to the prevention of heart attack or stroke in the majority of persons with VTE cannot be recommended at present.

    Objectives The long term effects (>20 years) of anabolic‐androgenic steroid (AAS) use on plasma concentrations of homocysteine (HCY), folate, testosterone, sex hormone binding globulin (SHBG), free androgen index, urea, creatinine, haematocrit (HCT), vitamin B12, and urinary testosterone/epitestosterone (T/E) ratio, were examined in a cohort of self‐prescribing bodybuilders. Methods Subjects (n = 40) were divided into four distinct groups: (1) AAS users still using AAS (SU; n = 10); (2) AAS users abstinent from AAS administration for 3 months (SA; n = 10); (3) non‐drug using bodybuilding controls (BC; n = 10); and (4) sedentary male controls (SC; n = 10). Results HCY levels were significantly higher in SU compared with BC and SC (p<0.01), and with SA (p<0.05). Fat free mass was significantly higher in both groups of AAS users (p<0.01). Daily energy intake (kJ) and daily protein intake (g/day) were significantly higher in SU and SA (p<0.05) compared with BC and SC, but were unlikely to be responsible for the observed HCY increases. HCT concentrations were significantly higher in the SU group (p<0.01). A significant linear inverse relationship was observed in the SU group between SHBG and HCY (r = −0.828, p<0.01), indicating a possible influence of the sex hormones in determining HCY levels. Conclusions With mounting evidence linking AAS to adverse effects on some clotting factors, the significantly higher levels of HCY and HCT observed in the SU group suggest long term AAS users have increased risk of future thromboembolic events.

    Objectives Previous studies on the effect of statin adherence on cardiovascular events in the primary prevention of cardiovascular disease have adjusted for time-dependent confounding, but potentially introduced bias into their estimates as adherence and confounders were measured simultaneously. We aimed to evaluate the effect when accounting for time-dependent confounding affected by previous adherence as well as time sequence between factors. Design Retrospective cohort study. Setting Finnish healthcare registers. Participants Women aged 45–64 years initiating statin use for primary prevention of cardiovascular disease in 2001–2004 (n=42 807). Outcomes Acute cardiovascular event defined as a composite of acute coronary syndrome and acute ischaemic stroke was our primary outcome. Low-energy fractures were used as a negative control outcome to evaluate the healthy-adherer effect. Results During the 3-year follow-up, 474 women experienced the primary outcome event and 557 suffered a low-energy fracture. The causal HR estimated with marginal structural model for acute cardiovascular events for all the women who remained adherent (proportion of days covered ≥80%) to statin therapy during the previous adherence assessment year was 0.78 (95% CI: 0.65 to 0.94) when compared with everybody remaining non-adherent (proportion of days covered <80%). The result was robust against alternative model specifications. Statin adherers had a potentially reduced risk of experiencing low-energy fractures compared with non-adherers (HR 0.90, 95% CI 0.76 to 1.07). Conclusions Our study, which took into account the time dependence of adherence and confounders, as well as temporal order between these factors, is support for the concept that adherence to statins in women in primary prevention decreases the risk of acute cardiovascular events by about one-fifth in comparison to non-adherence. However, part of the observed effect of statin adherence on acute cardiovascular events

    Cardiac rehabilitation/secondary prevention programs are recognized as integral to the comprehensive care of patients with coronary heart disease, and as such are recommended in most contemporary clinical practice guidelines. The interventions are aimed at reducing disability, optimizing cardiovascular risk reduction by drug therapy and promoting healthy behavior. Healthy lifestyle habits must be recognized as capable of substantially reducing the risk for cardiovascular events in patients with coronary heart disease. This review highlights the recommended components of cardiac rehabilitation/secondary prevention programs, with special emphasis on regular physical activity.

    The role of citizen-scientists in collecting data and observations has been increasingly crucial in the last 10 years of atmospheric sciences. Meteonetwork is a non-profit organization founded by citizen scientists in 2002, in Lombardia, with the aim of raising public awareness about meteorological and climatological issues. Throughout the years the organization, besides the continuous holding of events such as meeting, conferences and talks, has been standing out because of its forum and its wide network of weather stations. Meteonetwork's forum is, in this field, the most read and followed in the country and with its 8459 members and over 4,217,505 posts turns out to be the 17th forum over the entire country. Its network is operated in cooperation with Centro Epson Meteo and collects amateur semi-professional stations distributed all over the Italian territory, providing real-time and daily data. It consists of 706 stations, among which more than 400 regularly updated; volunteers constantly work to perform quality control and ensure data reliability. Meteonetwork has also developed several collaborations with private and public institutions, among which DRIHM - Cima Research Foundation, Centro Epson Meteo di Milano, Arpa Veneto, Arpa Emilia-Romagna, Arpa Lombardia, Arpa Friuli - Venezia Giulia, Servizio Glaciologico Lombardo, C. N. R. - C. I. S. A, Università di Pisa, Università di Milano, University of Aberdeen, Protezione Civile - Regione Lombardia, Protezione Civile - Regione Piemonte stand out. As WMO emphasized in 2001 World Meteorological Day "Volunteers for the weather, climate and water" the contribution of citizen-scientists to scientific studies is remarkable. In this perspective Meteonetwork and the University of Milan, in April 2011, started a project of technical and scientific cooperation called Weatherness. The university is provided with data gathered by Meteoneonetwork's stations with the aim of improving the knowledge of the impact that heat

    Carotid atherosclerotic stenosis is a risk factor for ischemic stroke. The rapid development of neuroimaging techniques had led to carotid angioplasty with stenting (CAS) becoming a useful, effective and minimally invasive method for the treatment of extracranial carotid artery stenosis. The aim of the present study was to identify independent risk factors to predict perioperative major adverse cerebral and cardiovascular events for CAS patients and establish a risk evaluation model. Consecutive patients treated with a standardized CAS procedure were enrolled in the present study. The patients included underwent independent neurological evaluation prior to and after the procedure and at 30 days. The rates of transient ischemic attack, stroke, myocardial infarction and mortality were recorded. A relative regression model was established to evaluate risk factors of perioperative major adverse cardiac and cerebrovascular events (MACCE). In total, 403 subjects treated with CAS were enrolled into the study at a baseline MACCE rate of 8.19%, whereas the overall stroke, myocardial infarction and mortality rate at 30 days was 3.97%. The multiple regression analysis revealed that certain factors significantly predicted the 30-day risk of treatment-related MACCE. These factors included age of ≥70 years, ulcerative plaque, severe carotid stenosis, bilateral carotid artery stenting and hemodynamic depression following CAS. The MACCE risk prediction model and risk score system were subsequently established. In conclusion, factors that significantly predicted the 30-day risk of MACCE of CAS included, age of ≥70 years, ulcerative plaque, severe carotid stenosis, bilateral carotid artery stenting and hemodynamic depression, with hemodynamic depression being a controllable factor. The established risk score system is therefore a potentially useful tool that can be employed in the prediction of MACCE after CAS. PMID:27446318

    We ascertained the prevalence of self-reported late occurrence of diabetes, hypertension, and cardiovascular (CV) disease in 1089 hematopoietic cell transplantation (HCT) survivors who underwent HCT between 1974 and 1998, survived at least 2 years, and were not currently taking immunosuppressant agents and compared them with 383 sibling controls. All subjects completed a 255-item health questionnaire. The mean age at survey completion was 39.3 years for survivors and 38.6 years for siblings; mean follow-up was 8.6 years. Adjusting for age, sex, race, and body mass index (BMI), survivors of allogeneic HCT were 3.65 times (95% confidence interval [CI], 1.82-7.32) more likely to report diabetes than siblings and 2.06 times (95% CI, 1.39-3.04) more likely to report hypertension compared with siblings but did not report other CV outcomes with any greater frequency. Recipients of autologous HCTs were no more likely than siblings to report any of the outcomes studied. Allogeneic HCT survivors were also more likely to develop hypertension (odds ratio [OR] = 2.31; 95% CI, 1.45-3.67) than autologous recipients. Total body irradiation (TBI) exposure was associated with an increased risk of diabetes (OR = 3.42; 95% CI, 1.55-7.52). Thus, HCT survivors have a higher age- and BMI-adjusted risk of diabetes and hypertension, potentially leading to a higher than expected risk of CV events with age. PMID:17047152

    Thiazide diuretics are recommended as first-line therapy for hypertension and are among the most commonly prescribed drugs worldwide. According to their molecular structure, thiazide diuretics can be divided in thiazide-type (TT) and thiazide-like (TL) diuretics. TL diuretics have a longer elimination half-life compared with TT diuretics and have been shown to exert additional pharmacological effects, which may differently affect cardiovascular risk. In this meta-analysis, we compared the effects of TT and TL diuretics on cardiovascular events and mortality. Randomized, controlled studies in adult hypertensive patients that compared TT or TL diuretics with placebo or antihypertensive drugs and had ≥1 year follow-up were included. Primary outcome was cardiovascular events; secondary outcomes included coronary events, heart failure, cerebrovascular events, and all-cause mortality. Meta-regression analysis was used to identify confounders and correct for the achieved blood pressure reductions. Twenty-one studies with >480 000 patient-years were included. Outcomes were not affected by heterogeneity in age, sex, and ethnicity among included studies, whereas larger blood pressure reductions were significantly associated with increased risk reductions for all outcomes (P<0.001). Corrected for differences in office blood pressure reductions among trials, TL diuretics resulted in a 12% additional risk reduction for cardiovascular events (P=0.049) and a 21% additional risk reduction for heart failure (P=0.023) when compared with TT diuretics. The incidence of adverse events was comparable among TT, TL diuretics, and other antihypertensive therapy. Our data suggest that the best available evidence seems to favor TL diuretics as the drug of choice when thiazide treatment is considered for hypertension.

    ESO and the Government of Chile launched today the book "10 Years Exploring the Universe", written by the beneficiaries of the ESO-Chile Joint Committee. This annual fund provides grants for individual Chilean scientists, research infrastructures, scientific congresses, workshops for science teachers and astronomy outreach programmes for the public. In a ceremony held in Santiago on 19 June 2006, the European Organisation for Astronomical Research in the Southern Hemisphere (ESO) and the Chilean Ministry of Foreign Affairs marked the 10th Anniversary of the Supplementary Agreement, which granted to Chilean astronomers up to 10 percent of the total observing time on ESO telescopes. This agreement also established an annual fund for the development of astronomy, managed by the so-called "ESO-Chile Joint Committee". ESO PR Photo 21/06 ESO PR Photo 21/06 Ten Years ESO-Chile Agreement Ceremony The celebration event was hosted by ESO Director General, Dr. Catherine Cesarsky, and the Director of Special Policy for the Chilean Ministry of Foreign Affairs, Ambassador Luis Winter. "ESO's commitment is, and always will be, to promote astronomy and scientific knowledge in the country hosting our observatories", said ESO Director General, Dr. Catherine Cesarsky. "We hope Chile and Europe will continue with great achievements in this fascinating joint adventure, the exploration of the universe." On behalf of the Government of Chile, Ambassador Luis Winter outlined the historical importance of the Supplementary Agreement, ratified by the Chilean Congress in 1996. "Such is the magnitude of ESO-Chile Joint Committee that, only in 2005, this annual fund represented 8 percent of all financing sources for Chilean astronomy, including those from Government and universities", Ambassador Winter said.

    After breast conserving surgery, early stage breast cancer patients are currently treated with a wide range of radiation techniques including whole breast irradiation (WBI), accelerated partial breast irradiation (APBI) using high-dose rate (HDR) brachytherapy, or 3D-conformal radiotherapy (3D-CRT). This study compares the mean heart’s doses for a left breast irradiated with different breast techniques. An anthropomorphic Rando phantom was modified with gelatin-based breast of different sizes and tumors located medially or laterally. The breasts were treated with WBI, 3D-CRT, or HDR APBI. The heart’s mean doses were measured with Gafchromic films and controlled with optically stimulated luminescent dosimeters. Following the model reported by Darby (1), major cardiac were estimated assuming a linear risk increase with the mean dose to the heart of 7.4% per gray. WBI lead to the highest mean heart dose (2.99 Gy) compared to 3D-CRT APBI (0.51 Gy), multicatheter (1.58 Gy), and balloon HDR (2.17 Gy) for a medially located tumor. This translated into long-term coronary event increases of 22, 3.8, 11.7, and 16% respectively. The sensitivity analysis showed that the tumor location had almost no effect on the mean heart dose for 3D-CRT APBI and a minimal impact for HDR APBI. In case of WBI large breast size and set-up errors lead to sharp increases of the mean heart dose. Its value reached 10.79 Gy for women with large breast and a set-up error of 1.5 cm. Such a high value could increase the risk of having long-term coronary events by 80%. Comparison among different irradiation techniques demonstrates that 3D-CRT APBI appears to be the safest one with less probability of having cardiovascular events in the future. A sensitivity analysis showed that WBI is the most challenging technique for patients with large breasts or when significant set-up errors are anticipated. In those cases, additional heart shielding techniques are required. PMID:25374841

    Background It is unclear whether levels of high-density lipoprotein cholesterol (HDL-C) or apolipoprotein A-I (apoA-I) remain inversely associated with cardiovascular risk among patients who achieve very low levels of low-density lipoprotein cholesterol (LDL-C) on statin therapy. It is also unknown whether a rise in HDL-C or apoA-I after initiation of statin therapy is associated with a reduced cardiovascular risk. Methods and results We performed a meta-analysis of 8 statin trials in which lipids and apolipoproteins were determined in all study participants at baseline and at 1-year follow-up. Individual patient data were obtained for 38,153 trial participants allocated to statin therapy, of whom 5387 suffered a major cardiovascular event. HDL-C levels were associated with a reduced risk of major cardiovascular events (adjusted hazard ratio 0.83, 95%CI 0.81–0.86 per 1 standard deviation increment), as were apoA-I levels (HR 0.79, 95%CI 0.72–0.82). This association was also observed among patients achieving on-statin LDL-C levels < 50 mg/dL. An increase of HDL-C was not associated with reduced cardiovascular risk (HR 0.98, 95%CI 0.94–1.01 per 1 standard deviation increment), whereas a rise in apoA-I was (HR 0.93, 95%CI 0.90–0.97). Conclusions Among patients treated with statin therapy, HDL-C and apoA-I levels were strongly associated with a reduced cardiovascular risk, even among those achieving very low LDL-C. An apoA-I increase was associated with a reduced risk of major cardiovascular events, whereas for HDL-C this was not the case. These findings suggest that therapies that increase apoA-I concentration require further exploration with regard to cardiovascular risk reduction. PMID:23965489

  16. Effects of lipid-lowering therapy on reduction of cardiovascular events in patients with end-stage renal disease requiring hemodialysis.

    In the general population, dyslipidemia is an established independent risk factor for cardiovascular disease. In patients with end-stage renal disease (ESRD), comorbid cardiovascular disease is present at alarming rates, and those who require hemodialysis and have cardiovascular disease continue to have a high mortality rate. Lipid abnormalities associated with chronic kidney disease (CKD) vary depending on the stage of disease (stages 1-5), but low-density lipoprotein cholesterol (LDL) has been established as the primary lipid treatment target. Guidelines support an LDL level of less than 100 mg/dl in patients with all stages of CKD, except when the triglyceride level is above 500 mg/dl. As patients progress to stage 5 CKD (ESRD with hemodialysis), the high triglyceride, low high-density lipoprotein cholesterol, and increased lipoprotein(a) levels of the early stages become more pronounced, with increases in small dense LDL particles; however, total cholesterol and LDL values remain normal or decrease. In patients undergoing hemodialysis, lipid abnormalities are driven by an increase in hepatic secretion and delayed catabolism of very low-density lipoproteins, as well as a reduction in lipoprotein lipase and hepatic lipase. Epidemiologic data support the role of cholesterol lowering as a means to lower cardiovascular events in the hemodialysis population. We conducted a literature search of various databases (1966-September 2009) to identify relevant clinical trials that evaluated the efficacy and safety of multiple lipid-lowering agents for the treatment of dyslipidemia in patients with ESRD requiring hemodialysis. Only those trials that used clinical primary end points of coronary heart disease (e.g., cardiovascular death, myocardial infarction, stroke) were included in this review. Evidence demonstrates that 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor (statin) therapy (i.e., atorvastatin and rosuvastatin) significantly reduces surrogate

    This article reports the rationale for the Brazilian Cardioprotective Nutritional Program (BALANCE Program) Trial. This pragmatic, multicenter, nationwide, randomized, concealed, controlled trial was designed to investigate the effects of the BALANCE Program in reducing cardiovascular events. The BALANCE Program consists of a prescribed diet guided by nutritional content recommendations from Brazilian national guidelines using a unique nutritional education strategy, which includes suggestions of affordable foods. In addition, the Program focuses on intensive follow-up through one-on-one visits, group sessions, and phone calls. In this trial, participants 45 years or older with any evidence of established cardiovascular disease will be randomized to the BALANCE or control groups. Those in the BALANCE group will receive the afore mentioned program interventions, while controls will be given generic advice on how to follow a low-fat, low-energy, low-sodium, and low-cholesterol diet, with a view to achieving Brazilian nutritional guideline recommendations. The primary outcome is a composite of death (any cause), cardiac arrest, acute myocardial infarction, stroke, myocardial revascularization, amputation for peripheral arterial disease, or hospitalization for unstable angina. A total of 2468 patients will be enrolled in 34 sites and followed up for up to 48 months. If the BALANCE Program is found to decrease cardiovascular events and reduce risk factors, this may represent an advance in the care of patients with cardiovascular disease.

    Previously we have shown that a functional nonsynonymous single nucleotide polymorphism (rs6318) of the 5HTR2C gene located on the X-chromosome is associated with hypothalamic-pituitary-adrenal axis response to a stress recall task, and with endophenotypes associated with cardiovascular disease (CVD). These findings suggest that individuals carrying the rs6318 Ser23 C allele will be at higher risk for CVD compared to Cys23 G allele carriers. The present study examined allelic variation in rs6318 as a predictor of coronary artery disease (CAD) severity and a composite endpoint of all-cause mortality or myocardial infarction (MI) among Caucasian participants consecutively recruited through the cardiac catheterization laboratory at Duke University Hospital (Durham, NC) as part of the CATHGEN biorepository. Study population consisted of 6,126 Caucasian participants (4,036 [65.9%] males and 2,090 [34.1%] females). A total of 1,769 events occurred (1,544 deaths and 225 MIs; median follow-up time =  5.3 years, interquartile range  = 3.3–8.2). Unadjusted Cox time-to-event regression models showed, compared to Cys23 G carriers, males hemizygous for Ser23 C and females homozygous for Ser23C were at increased risk for the composite endpoint of all-cause death or MI: Hazard Ratio (HR)  = 1.47, 95% confidence interval (CI)  = 1.17, 1.84, p  = .0008. Adjusting for age, rs6318 genotype was not related to body mass index, diabetes, hypertension, dyslipidemia, smoking history, number of diseased coronary arteries, or left ventricular ejection fraction in either males or females. After adjustment for these covariates the estimate for the two Ser23 C groups was modestly attenuated, but remained statistically significant: HR  = 1.38, 95% CI = 1.10, 1.73, p = .005. These findings suggest that this functional polymorphism of the 5HTR2C gene is associated with increased risk for CVD mortality and morbidity, but this association is apparently not

    Rates of ESRD are rising faster in Hispanic than non-Hispanic white individuals, but reasons for this are unclear. Whether rates of cardiovascular events and mortality differ among Hispanic and non-Hispanic white patients with chronic kidney disease (CKD) also is not well understood. Therefore, this study examined the associations between Hispanic ethnicity and risks for ESRD, cardiovascular events, and death in patients with CKD. A total of 39,550 patients with stages 3 to 4 CKD from Kaiser Permanente of Northern California were included. Hispanic ethnicity was obtained from self-report supplemented by surname matching. GFR was estimated from the abbreviated Modification of Diet in Renal Disease equation, and clinical outcomes, patient characteristics, and longitudinal medication use were ascertained from health plan databases and state mortality files. After adjustment for sociodemographic characteristics, Hispanic ethnicity was associated with an increased risk for ESRD (hazard ratio [HR] 1.93; 95% confidence interval [CI] 1.72 to 2.17) when compared with non-Hispanic white patients, which was attenuated after controlling for diabetes and insulin use (HR 1.50; 95% CI 1.33 to 1.69). After further adjustment for potential confounders, Hispanic ethnicity remained independently associated with an increased risk for ESRD (HR 1.33; 95% CI 1.17 to 1.52) as well as a lower risk for cardiovascular events (HR 0.82; 95% CI 0.76 to 0.88) and death (HR 0.72; 95% CI 0.66 to 0.79). Among a large cohort of patients with CKD, Hispanic ethnicity was associated with lower rates of death and cardiovascular events and a higher rate of progression to ESRD. The higher prevalence of diabetes among Hispanic patients only partially explained the increased risk for ESRD. Further studies are required to elucidate the cause(s) of ethnic disparities in CKD-associated outcomes.

    In 1988 Bonneville Power Administration (BPA) began work on this Operations, Maintenance, and Replacement 10-Year Plan to develop a levelized program that would assure high system reliability. During the Programs in Perspective (PIP) meetings in the late summer and fall of 1988, many of the concerns to be addressed in an Operations, Maintenance, and Replacement Plan were identified. Following these PIP meetings BPA established internal work groups. During the winter and spring of 1989, these work groups developed technical background and issue papers on topics that ranged from substation maintenance to environmental protection. In addition, a customer forum group was established and met on several occasions to review work on the plan, to offer ideas and points of view, and to assure that BPA understood customer concerns. Based on recommendations from the work group reports and customer input, BPA's O M Management Team developed the draft Operations, Maintenance, and Replacement 10-Year Plan that was released for public comment during the spring of 1990. During the public review period, BPA received a number of written comments from customers and the interested public. In addition, special meetings were held with interested customers. This final Operations, Maintenance, and Replacement 10-Year Plan reflects BPA's response to customers and interested public on each topic discussed in the 10-Year Plan. The plan is a distillation of BPA's strategies to achieve a levelized program over 10 years.

    Background and objective The optimal BP target to reduce adverse clinical outcomes in patients with CKD is unclear. This study examined the relationship between BP and death, cardiovascular events (CVEs), and kidney disease progression in patients with advanced kidney disease. Design, setting, participants, & measurements The relationship of systolic BP (SBP), diastolic BP (DBP), and pulse pressure (PP) with death, CVE, and progression to long-term dialysis was examined in 1099 patients with advanced CKD (eGFR≤30 ml/min per 1.7 3m2; not receiving dialysis) who participated in the Homocysteine in Kidney and ESRD study. That study enrolled participants from 2001 to 2003. Cox proportional hazard models were used to examine the association between BP and adverse outcomes. Results The mean±SD baseline eGFR was 18±7 ml/min per 1.73 m2. During a median follow-up of 2.9 years, 453 patients died, 215 had a CVE, and 615 initiated long-term dialysis. After adjustment for demographic characteristics and confounders, SBP, DBP, and PP were not associated with a higher risk of death. SBP and DBP were also not associated with CVE. The highest quartile of PP was associated with a substantial higher risk of CVE compared with the lowest quartile (hazard ratio [HR], 1.67; 95% confidence interval [95% CI], 1.10 to 2.52). The highest quartiles of SBP (HR, 1.28; 95% CI, 1.01 to 1.61) and DBP (HR, 1.36; 95% CI, 1.07 to 1.73), but not PP, were associated with a higher risk of progression to long-term dialysis compared with the lowest quartile. Conclusions In patients with advanced kidney disease not undergoing dialysis, higher PP was strongly associated with CVE whereas higher SBP and DBP were associated with progression to long-term dialysis. These results suggest that SBP and DBP should not be the only factors considered in determining antihypertensive therapy; elevated PP should also be considered. PMID:25979975

    Objectives Lower levels of low density lipoprotein (LDL-C) may be associated with increased cardiovascular (CV) risk in rheumatoid arthritis (RA). We studied whether the complex relationship between LDL-C and high density lipoprotein cholesterol (HDL-C) levels with CV risk is different in RA compared to non-RA. Methods Using data from a US health insurance plan (2003–2012), we conducted a cohort study that included RA and non-RA patients matched on age, sex and index date. Non-linearity between lipid levels and major adverse CV events (MACE) was tested. We used multivariable Cox proportional hazards regression models to examine for an interaction between lipids and RA on the risk of MACE, adjusting for CV risk factors. Results We studied 16,085 RA and 48,499 non-RA subjects with mean age 52.6 years and 78.6% women. The relationship between LDL-C and MACE was non-linear and similar between RA and non-RA (p for interaction=0.72). We observed no significant increase in CV risk between the lowest LDL-C quintile (<91.g/dL) and successive quintiles until the highest quintile (>190.0mg/dL) was compared; hazard ratio (HR) 1.40,95%CI 1.17,1.68). The relationship between HDL and MACE was also non-linear and similar in RA and non-RA (p for interaction=0.39). Compared to the lowest HDL-C quintile, each successive quintile was associated with reduced risk of MACE [lowest (<43.0mg/dL) vs highest quintile (>71.0mg/dL), HR 0.45,95%CI 0.48,0.72]. Conclusions The complex relationship between LDL-C, HDL-C and MACE was non-linear in RA and also not statistically different from an age- and sex-matched non-RA cohort. PMID:25917955

    In the past 10 years, immersion lithography has been the most effective high volume manufacturing method for the critical layers of semiconductor devices. Thinking of the next 10 years, we can expect continuous improvement on existing 300 mm wafer scanners with better accuracy and throughput to enhance the total output value per input cost. This value productivity, however, can be upgraded also by larger innovations which might happen in optical lithography. In this paper, we will discuss the possibilities and the impossibilities of potential innovation ideas of optical lithography, which are 450 mm wafer, optical maskless, multicolor lithography, and metamaterial.

    Background Limited evidence exists regarding the utility of genetic risk scores (GRS) in predicting recurrent cardiovascular events after acute coronary syndrome (ACS). We sought to determine whether a GRS would predict early recurrent cardiovascular events within 1 year of ACS. Methods & Results Participants admitted with acute coronary syndromes from the RISCA, PRAXY, and TRIUMPH cohorts, were genotyped for 30 single nucleotide polymorphisms (SNPs) associated with coronary artery disease (CAD) or myocardial infarction (MI) in prior genome wide association studies. A 30 SNP CAD/MI GRS was constructed. The primary endpoint was defined as all-cause mortality, recurrent ACS or cardiac re-hospitalization within 1 year of ACS admission. Results across all cohorts for the 30 SNP CAD/MI GRS were pooled using a random-effects model. There were 1040 patients from the RISCA cohort, 691 patients from the PRAXY cohort, and 1772 patients from the TRIUMPH cohort included in the analysis and 389 occurrences of the primary endpoint of recurrent events at 1-year post-ACS. In unadjusted and fully adjusted analyses, a 30 SNP GRS was not significantly associated with recurrent events (HR per allele 0.97 (95%CI 0.91–1.03) for RISCA, HR 0.99 (95%CI 0.93–1.05) for PRAXY, 0.98 (95%CI 0.94–1.02) for TRIUMPH, and 0.98 (95%CI 0.95–1.01) for the pooled analysis). Addition of this GRS to the GRACE risk model did not significantly improve risk prediction. Conclusion The 30 MI SNP GRS was not associated with recurrent events 1-year post ACS in pooled analyses across cohorts and did not improve risk discrimination or reclassification indices. Our results suggest that the genetic etiology of early events post-ACS may differ from later events. PMID:26232166

    PubMed

    Peña, José; Claro, Juan Carlos

    2014-05-01

    Patients with chronic kidney disease have an increased cardiovascular risk. Several non-traditional factors have been showed to be associated with this risk, including hyperhomocysteinemia. The effects of reducing homocysteine levels with folic acid supplementation have been studied in a number of randomized trials, with mixed results. In this article we critically appraise two systematic reviews providing disparate conclusions about this question and we summarize their main findings using the GRADE methodology. We conclude that there are methodological differences that may explain the mixed results in both systematic reviews. Folic acid supplementation does not reduce cardiovascular morbidity or mortality in patients with chronic kidney disease at any stage.

    In the Losartan Intervention for End Point Reduction in Hypertension (LIFE) study, 4.8 years' losartan- versus atenolol-based antihypertensive treatment reduced left ventricular hypertrophy and cardiovascular end points, including cardiovascular death and stroke. However, there was no difference in myocardial infarction (MI), possibly related to greater reduction in myocardial oxygen demand by atenolol-based treatment. Myocardial oxygen demand was assessed indirectly by the left ventricular mass×wall stress×heart rate (triple product) in 905 LIFE participants. The triple product was included as time-varying covariate in Cox models assessing predictors of the LIFE primary composite end point (cardiovascular death, MI, or stroke), its individual components, and all-cause mortality. At baseline, the triple product in both treatment groups was, compared with normal adults, elevated in 70% of patients. During randomized treatment, the triple product was reduced more by atenolol, with prevalences of elevated triple product of 39% versus 51% on losartan (both P≤0.001). In Cox regression analyses adjusting for age, smoking, diabetes mellitus, and prior stroke, MI, and heart failure, 1 SD lower triple product was associated with 23% (95% confidence interval 13%-32%) fewer composite end points, 31% (18%-41%) less cardiovascular mortality, 30% (15%-41%) lower MI, and 22% (11%-33%) lower all-cause mortality (all P≤0.001), without association with stroke (P=0.34). Although losartan-based therapy reduced ventricular mass more, greater heart rate reduction with atenolol resulted in larger reduction of the triple product. Lower triple product during antihypertensive treatment was strongly, independently associated with lower rates of the LIFE primary composite end point, cardiovascular death, and MI, but not stroke.

    Renal dysfunction is related to long-term mortality and myocardial infarction after coronary artery bypass grafting (CABG). We aimed to investigate the association between preoperative renal dysfunction and early risk of stroke, myocardial infarction, or heart failure after CABG. From the Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies registry, we included all 36,284 patients who underwent primary isolated CABG from 2000 to 2008 in Sweden. The Swedish National Inpatient Registry was used to obtain the primary end point, which was rehospitalization for stroke, myocardial infarction, or heart failure ≤90 days after CABG. Logistic regression models were used to estimate the risk for the primary outcome and the secondary outcome of death from any cause, while adjusting for confounders. During 90 days of follow-up, there were 2,462 cardiovascular events and 617 deaths. In total, 17% of patients developed acute kidney injury postoperatively. Odds ratios with 95% confidence intervals for cardiovascular events after adjustment for age, gender, atrial fibrillation, left ventricular ejection fraction, diabetes mellitus, peripheral vascular disease, and history of myocardial infarction, heart failure, or stroke was 1.24 (1.06 to 1.45) in patients with an estimated glomerular filtration rate of 15 to 45 ml/min/1.73 m(2) but became nonsignificant after acute kidney injury was introduced into the statistical model. The risk of death was significantly increased in patients with estimated glomerular filtration rate of 15 to 45 ml/min/1.73 m(2) (odds ratio 1.76, 95% confidence interval 1.38 to 2.25) even after adjustment for all confounders. Renal dysfunction was associated with all-cause mortality but not with cardiovascular events during the first 3 postoperative months after primary isolated CABG.

    Macrophagic myofasciitis (MMF) is an uncommon inflammatory disorder of muscle believed to be due to persistence of vaccine-derived aluminium hydroxide at the site of injection. The condition is characterised by diffuse myalgias, arthralgia and fatigue. We describe a patient with histologically confirmed MMF whose presentation was atypical with left chest and upper limb pain beginning more than 10 years post vaccination. Treatment with steroids led to symptomatic improvement. Although rare, clinicians should consider MMF in cases of atypical myalgia.

    This study was undertaken to quantify 10-year evapotranspiration (ET) in a tropical rainforest, Sarawak, Malaysia. To this aim, a simplified big-leaf model was formulated, which can consider transpiration (Et) and rainfall interception (Ei). The model was independently validated using eddy covariance fluxes, rainfall interception based on throughfall and stemflow measurements, and sap flow measurements conducted for more than two years. Consequently, our big-leaf model could successfully reproduce Et and Ei. By using the model and a 10-year meteorological data set, Et, Ei, and ET was estimated in the period between 2000 and 2009. The annual Et , Ei, and ET averaged over 10 years were estimated as 1114, 209, and 1323 mm, respectively, with the small seasonal fluctuations. The derived estimations for 10 years showed conservative year-to-year variations in Et, Ei, and ET (CV = 5-7%) against considerable year-to-year variations in annual rainfall (CV = 11%). Specific rainfall characteristics in this site could be a reason for conservative year-to-year variations in Ei. Small interannual variations in meteorological conditions and no occurrence of unusually severe drought in this study period could be a reason for the small year-to-year variations in Et. As well, we compared ET, Ei at this site with those of other tropical forests. Our forest ET was smaller than global maximum value of ET estimated in other tropical forests because of the smaller Ei, relative to annual rainfall at this site. Based on the derived characteristics of ET, we also discussed possible changes in ET, Et, and Ei in response to changes in rainfall regime at this site.

    Background Herpes zoster is common and can have serious consequences. Additionally, emerging data suggest an increased risk of acute cardiovascular events following herpes zoster. However, to our knowledge, existing association studies compare outcomes between individuals and are therefore vulnerable to between-person confounding. In this study, we used a within-person study design to quantify any short-term increased risk of acute cardiovascular events (stroke and myocardial infarction [MI]) after zoster and to assess whether zoster vaccination modifies this association. Methods and Findings The self-controlled case series method was used to estimate rates of stroke and acute MI in defined periods after herpes zoster compared to other time periods, within individuals. Participants were fully eligible Medicare beneficiaries aged ≥65 y with a herpes zoster diagnosis and either an ischemic stroke (n = 42,954) or MI (n = 24,237) between 1 January 2006 and 31 December 2011. Age-adjusted incidence ratios (IRs) for stroke and MI during predefined periods up to 12 mo after zoster relative to unexposed time periods were calculated using conditional Poisson regression. We observed a marked increase in the rate of acute cardiovascular events in the first week after zoster diagnosis: a 2.4-fold increased ischemic stroke rate (IR 2.37, 95% CI 2.17–2.59) and a 1.7-fold increased MI rate (IR 1.68, 95% CI 1.47–1.92), followed by a gradual resolution over 6 mo. Zoster vaccination did not appear to modify the association with MI (interaction p-value = 0.44). We also found no evidence for a difference in the IR for ischemic stroke between vaccinated (IR 1.14, 95% CI 0.75–1.74) and unvaccinated (IR 1.78, 95% CI 1.68–1.88) individuals during the first 4 wk after zoster diagnosis (interaction p-value = 0.28). The relatively few vaccinated individuals limited the study’s power to assess the role of vaccination. Conclusions Stroke and MI rates are transiently increased after

    Background and purpose Total knee replacement (TKR) in younger patients using cemented components has shown inferior results, mainly due to aseptic loosening. Excellent clinical results have been reported with components made of trabecular metal (TM). In a previous report, we have shown stabilization of the TM tibial implants for up to 5 years. In this study, we compared the clinical and RSA results of these uncemented implants with those of cemented implants. Patients and methods 41 patients (47 knees) aged ≤ 60 years underwent TKR. 22 patients (26 knees) received an uncemented monoblock cruciate-retaining (CR) tibial component (TM) and 19 patients (21 knees) received a cemented NexGen Option CR tibial component. Follow-up examination was done at 10 years, and 16 patients (19 knees) with TM tibial components and 17 patients (18 knees) with cemented tibial components remained for analysis. Results 1 of 19 TM implants was revised for infection, 2 of 18 cemented components were revised for knee instability, and no revisions were done for loosening. Both types of tibial components migrated in the first 3 months, the TM group to a greater extent than the cemented group. After 3 months, both groups were stable during the next 10 years. Interpretation The patterns of migration for uncemented TM implants and cemented tibial implants over the first 10 years indicate that they have a good long-term prognosis regarding fixation PMID:27357222

Rapid vertical growth of cottonwoods (circa 2 - 3 m / yr) resulted in sites with forest structure that supported greater species richness of breeding birds, increased Shannon diversity indices, and supported greater territory densities than on sites planted with slower-growing oak species. Grassland birds (Spiza americana [Dickcissel], and Sturnella magna [Eastern Meadowlark]) were indicative of species breeding on oak-dominated reforestation # 10 years old. Agelaius phoeniceus (Red-winged Blackbird) and Colinus virginianus (Northern Bobwhite) characterized cottonwood reforestation # 4 years old, whereas 14 species of shrub-scrub birds (e.g., Passerina cyanea [Indigo Bunting]) and early-successional forest birds (e.g., Vireo gilvus [Warbling Vireo]) typified cottonwood reforestation 5 to 9 years after planting. Rates of daily nest survival did not differ between reforestation strategies. Nest parasitism increased markedly in older cottonwood stands, but was overwhelmed by predation as a cause of nest failure. Based on Partners in Flight prioritization scores and territory densities, the value of cottonwood reforestation for avian conservation was significantly greater than that of oak reforestation during their first 10 years. Because of benefits conferred on breeding birds, we recommend reforestation of bottomland hardwoods include a high proportion of fast-growing, early successional species such as cottonwood.

    Background and purpose - Total knee replacement (TKR) in younger patients using cemented components has shown inferior results, mainly due to aseptic loosening. Excellent clinical results have been reported with components made of trabecular metal (TM). In a previous report, we have shown stabilization of the TM tibial implants for up to 5 years. In this study, we compared the clinical and RSA results of these uncemented implants with those of cemented implants. Patients and methods - 41 patients (47 knees) aged ≤ 60 years underwent TKR. 22 patients (26 knees) received an uncemented monoblock cruciate-retaining (CR) tibial component (TM) and 19 patients (21 knees) received a cemented NexGen Option CR tibial component. Follow-up examination was done at 10 years, and 16 patients (19 knees) with TM tibial components and 17 patients (18 knees) with cemented tibial components remained for analysis. Results - 1 of 19 TM implants was revised for infection, 2 of 18 cemented components were revised for knee instability, and no revisions were done for loosening. Both types of tibial components migrated in the first 3 months, the TM group to a greater extent than the cemented group. After 3 months, both groups were stable during the next 10 years. Interpretation - The patterns of migration for uncemented TM implants and cemented tibial implants over the first 10 years indicate that they have a good long-term prognosis regarding fixation.

    The Marine Metadata Interoperability project (http://marinemetadata.org) held its public opening at AGU's 2004 Fall Meeting. For 10 years since that debut, the MMI guidance and vocabulary sites have served over 100,000 visitors, with 525 community members and continuous Steering Committee leadership. Originally funded by the National Science Foundation, over the years multiple organizations have supported the MMI mission: "Our goal is to support collaborative research in the marine science domain, by simplifying the incredibly complex world of metadata into specific, straightforward guidance. MMI encourages scientists and data managers at all levels to apply good metadata practices from the start of a project, by providing the best guidance and resources for data management, and developing advanced metadata tools and services needed by the community." Now hosted by the Harte Research Institute at Texas A&M University at Corpus Christi, MMI continues to provide guidance and services to the community, and is planning for marine science and technology needs for the next 10 years. In this presentation we will highlight our major accomplishments, describe our recent achievements and imminent goals, and propose a vision for improving marine data interoperability for the next 10 years, including Ontology Registry and Repository (http://mmisw.org/orr) advancements and applications (http://mmisw.org/cfsn).

    Introduction. The prognosis of acute coronary syndrome (ACS) patients has been improved with several treatments such as antithrombotics, beta-blockers, and angiotensin-converting enzyme inhibitors (ACEI) as well as coronary revascularization. Influenza vaccination has been shown to reduce adverse outcomes in ACS, but no information exists regarding the interaction of other treatments. Methods. This study included 439 ACS patients from Phrommintikul et al. A single dose of inactivated influenza vaccine was given by intramuscular injection in the vaccination group. The cardiovascular outcomes were described as major cardiovascular events (MACEs) which included mortality, hospitalization due to ACS, and hospitalization due to heart failure (HF). The stratified and multivariable Cox's regression analysis was performed. Results. The stratified Cox's analysis by influenza vaccination for each cardiovascular outcome and discrimination of hazard ratios showed that beta-blockers had an interaction with influenza vaccination. Moreover, the multivariable hazard ratios disclosed that influenza vaccine is associated with a significant reduction of hospitalization due to HF in patients who received beta-blockers (HR = 0.05, 95% CI = 0.004-0.71, P = 0.027), after being adjusted for prognostic indicators (sex, dyslipidemia, serum creatinine, and left ventricular ejection fraction). Conclusions. The influenza vaccine was shown to significantly modify the effect of beta-blockers in ACS patients and to reduce the hospitalization due to HF. However, further study of a larger population and benefits to HF patients should be investigated. PMID:27200206

    Summary Background Carotid intima-media thickness (cIMT) is related to the risk of cardiovascular events in the general population. An association between changes in cIMT and cardiovascular risk is frequently assumed but has rarely been reported. Our aim was to test this association. Methods We identified general population studies that assessed cIMT at least twice and followed up participants for myocardial infarction, stroke, or death. The study teams collaborated in an individual participant data meta-analysis. Excluding individuals with previous myocardial infarction or stroke, we assessed the association between cIMT progression and the risk of cardiovascular events (myocardial infarction, stroke, vascular death, or a combination of these) for each study with Cox regression. The log hazard ratios (HRs) per SD difference were pooled by random effects meta-analysis. Findings Of 21 eligible studies, 16 with 36 984 participants were included. During a mean follow-up of 7·0 years, 1519 myocardial infarctions, 1339 strokes, and 2028 combined endpoints (myocardial infarction, stroke, vascular death) occurred. Yearly cIMT progression was derived from two ultrasound visits 2–7 years (median 4 years) apart. For mean common carotid artery intima-media thickness progression, the overall HR of the combined endpoint was 0·97 (95% CI 0·94–1·00) when adjusted for age, sex, and mean common carotid artery intima-media thickness, and 0·98 (0·95–1·01) when also adjusted for vascular risk factors. Although we detected no associations with cIMT progression in sensitivity analyses, the mean cIMT of the two ultrasound scans was positively and robustly associated with cardiovascular risk (HR for the combined endpoint 1·16, 95% CI 1·10–1·22, adjusted for age, sex, mean common carotid artery intima-media thickness progression, and vascular risk factors). In three studies including 3439 participants who had four ultrasound scans, cIMT progression did not correlate

    The ankle-brachial blood pressure index (ABPI) has been recognized to have a predictive value for cardiovascular (CV) events and mortality in general or dialysis populations. However, the associations between ABPI and those outcomes have not been fully investigated in predialysis patients. The present study aimed to clarify the relationships between ABPI and both CV events and mortality in Japanese chronic kidney disease (CKD) patients not on dialysis. In this prospective observational study, we enrolled 320 patients with CKD stages 3-5 who were not on dialysis. At baseline, ABPI was examined and a low ABPI was defined as <0.9. CV events and all-cause deaths were examined in each patient. A Cox proportional hazards model was applied to determine the risk factors for CV events, as well as for mortality from CV and all causes. The median follow-up period was 30 months. CV events occurred in 56 patients and all-cause deaths occurred in 48, including 20 CV deaths. Multivariate analysis showed that age and low ABPI were risk factors for CV events. It was demonstrated that age, a history of cerebrovascular disease and low ABPI were determined as independent risk factors for CV mortality. In addition, age, body mass index and low ABPI were independently associated with all-cause mortality. In patients with CKD, low ABPI during the predialysis period is independently associated with poor survival and CV events, suggesting the usefulness of measuring ABPI for predicting CV events and patient survival in CKD.

    There is wide variation in response to antiplatelet therapy and high on-treatment platelet reactivity is associated with adverse cardiovascular events. The objective here was to determine whether the results of a novel strategy for assessing platelet reactivity (based on P-selectin measurement) are associated with clinical outcomes in patients with acute coronary syndromes (ACS). This was a prospective cohort study of 100 ACS patients taking aspirin and clopidogrel. P-selectin tests designed to assess response to P2Y12 antagonists or aspirin were performed alongside light transmission aggregometry. For the P2Y12 P-selectin test, an optimal cutoff for high platelet reactivity was determined by receiver operating characteristic (ROC) curve analysis. Patients were divided into two cohorts based on this value: patients with (n = 42) or without (n = 58) high platelet reactivity. The primary endpoint was defined as the composite of cardiovascular death, myocardial infarction and stent thrombosis. After 12 months, the primary endpoint occurred in 12 patients. ROC curve analysis determined that the P2Y12 P-selectin test results were predictive of the primary endpoint (area under curve = 0.69, p = 0.046). The primary endpoint occurred more frequently in patients with high on-treatment platelet reactivity compared to those without (21.4% vs. 5.2%; hazard ratio (HR) 4.14; p = 0.026). The P2Y12 P-selectin test results correlated with light transmission aggregometry (Spearman p < 0.0001). Using the Aspirin P-selectin test, only two patients demonstrated high on-treatment platelet reactivity. This study suggests that a P2Y12 P-selectin test is capable of detecting high on-treatment platelet reactivity, which is associated with subsequent cardiovascular events.

    Background and objectives The calcimimetic cinacalcet reduced the risk of death or cardiovascular (CV) events in older, but not younger, patients with moderate to severe secondary hyperparathyroidism (HPT) who were receiving hemodialysis. To determine whether the lower risk in younger patients might be due to lower baseline CV risk and more frequent use of cointerventions that reduce parathyroid hormone (kidney transplantation, parathyroidectomy, and commercial cinacalcet use), this study examined the effects of cinacalcet in older (≥65 years, n=1005) and younger (<65 years, n=2878) patients. Design, setting, participants, & measurements Evaluation of Cinacalcet HCl Therapy to Lower Cardiovascular Events (EVOLVE) was a global, multicenter, randomized placebo-controlled trial in 3883 prevalent patients on hemodialysis, whose outcomes included death, major CV events, and development of severe unremitting HPT. The age subgroup analysis was prespecified. Results Older patients had higher baseline prevalence of diabetes mellitus and CV comorbidity. Annualized rates of kidney transplantation and parathyroidectomy were >3-fold higher in younger relative to older patients and were more frequent in patients randomized to placebo. In older patients, the adjusted relative hazard (95% confidence interval) for the primary composite (CV) end point (cinacalcet versus placebo) was 0.70 (0.60 to 0.81); in younger patients, the relative hazard was 0.97 (0.86 to 1.09). Corresponding adjusted relative hazards for mortality were 0.68 (0.51 to 0.81) and 0.99 (0.86 to 1.13). Reduction in the risk of severe unremitting HPT was similar in both groups. Conclusions In the EVOLVE trial, cinacalcet decreased the risk of death and of major CV events in older, but not younger, patients with moderate to severe HPT who were receiving hemodialysis. Effect modification by age may be partly explained by differences in underlying CV risk and differential application of cointerventions that reduce

    Research and practice in the area of motor speech disorders (MSDs) will change in the next 10 years, most likely in evolutionary rather revolutionary ways. We are likely to see an increase in the understanding of the underpinnings of MSDs and refinements in assessment and diagnosis. Management approaches probably will be refined, as will how outcomes are measured. The evidence base for treatment efficacy will grow. Technology and changes in the health care system will have strong and overarching, but not easily predicted, influences. This article provides a broad overview of these and related issues, with some cautious predictions. PMID:27232096

    Localized renal cell carcinoma (RCC) responds well to surgery. Patients often question how long they have to be on surveillance after their surgery. Several follow-up patterns have been described in the literature. Until 2009, no published established Canadian guidelines existed to assist Canadian health-care practitioners in the surveillance of these patients. We present 3 cases of RCC that recurred 10 years or longer after the initial nephrectomy. These cases emphasize the need for careful long-term follow-up, as recommended in the Canadian Urological Association guidelines. We also discuss the optimism of prolonged disease survival in the era of novel therapeutic agents that target angiogenesis. PMID:20368882

    December 2007 marks the 10-year anniversary of the first regulatory guidance for evaluation of drug-induced QT interval prolongation. A decade on, it seems surprising that this document, which was released by the Committee on Proprietary Medicinal Products, caused such acrimony in the industry. Sponsors now routinely evaluate their new drugs for an effect on cardiac electrophysiology in preclinical studies, in addition to obtaining ECGs in all phases of drug development and conducting a formal thorough QT study in humans.However, concurrently, new concerns have also emerged on broader issues related to the cardiovascular safety of drugs because of their potential to shorten the QT interval as well as to induce proischaemic, profibrotic or prothrombotic effects. Drugs may also have an indirect effect by adversely affecting one or more of the cardiovascular risk factors (e.g. through fluid retention or induction of dyslipidaemia). In addition to peroxisome proliferator-activated receptor agonists and cyclo-oxygenase 2 selective inhibitors, three other drugs, darbepoetin alfa, pergolide and tegaserod, provide a more contemporary regulatory stance on tolerance of cardiovascular risk of drugs and their benefit-risk assessment. This recent, more assertive, risk-averse stance has significant implications for future drug development. These include the routine evaluation of cardiovascular safety for certain classes of drugs. Drugs that are intended for long-term use will almost certainly require long-term clinical evaluation in studies that enrol populations that most closely resemble the ultimate target population. Novel mechanisms of action and biomarkers by themselves are no guarantee of improved safety or benefits. Even some traditional biomarkers have come to be viewed with scepticism. Requirements for more extensive and earlier postmarketing assessment of clinical benefits and rare, but serious risks associated with new medicinal products should create a new standard

    The relationship between psoriasis, chronic inflammation, cardiovascular risk and risk of cancer has long been debated. In addition, it has been suggested that alcohol consumption may be a risk factor for psoriasis onset and severity. The aim of this study was to develop evidence-based recommendations on the risk of comorbidities and its management for daily clinical use, focusing on cardiovascular risk, risk of cancer and alcohol use in psoriasis. A scientific committee identified and selected through the Delphi method clinically relevant questions about cardiovascular risk, risk of cancer and alcohol use in psoriasis. To address these questions, a systematic literature search was performed in Medline, Embase and the Cochrane Library databases. Systematic literature reviews including meta-analysis whenever possible were performed. Subsequently, an Expert board meeting involving 39 dermatologists took place to analyse the evidence and to elaborate recommendations on the selected questions. Recommendations were graded according to the Oxford level of evidence grading system. The degree of agreement of these recommendations was assessed on a 10-point scale, as well as their potential impact on daily clinical practice. A total of 3242 articles were identified through the systematic literature searches, among which 110 were included in the systematic reviews. Overall, 12 recommendations were elaborated regarding comorbidities management in psoriasis patients. A moderate increased risk of cardiovascular diseases (CVD), mainly myocardial infarction (MI) [meta-analysis of cohort studies: OR = 1.25 (95% CI 1.03-1.52) and of cross-sectional studies: OR = 1.57 (95% CI 1.08-2.27)], and coronary artery disease (CAD) [meta-analysis of cross-sectional: OR = 1.19 (95% CI 1.14-1.24), of cohort studies: OR = 1.20 (95% CI 1.13-1.27) and of case-control studies: OR = 1.84 (95% CI 1.09-3.09)] was acknowledged. This increased cardiovascular risk requires appropriate prevention

    Two years ago, BPA released its first-ever Operations, Maintenance, and Replacement (OM&R) 10-Year Plan. That effort broke new ground and was an extensive look at the condition of Operations, Maintenance, and Replacement on BPA`s power system. This document -- the 1992 OM&R 10-Year Plan -- uses that original plan as its foundation. It takes a look at how well BPA has accomplished the challenging task set out in the 1990 Plan. The 1992 Plan also introduces the Construction Program. Construction`s critical role in these programs is explored, and the pressures of construction workload -- such as the seasonal nature of the work and the broad swings in workload between projects and years -- are discussed. The document then looks at how situations may have changed with issues explored initially in the 1990 Plan. Importantly, this Plan also surfaces and explains some new issues that threaten to impact BPA`s ability to accomplish its OM&R workload. Finally, the document focuses on the revised strategies for Operations, Maintenance, Replacement, Construction, and Environment for the 1992 to 2001 time period, including the financial and human resources needed to accomplish those strategies.

    Expanding upon Pimbblet's 2011 analysis of career h-indices for members of the Astronomical Society of Australia, we provide additional citation metrics which are geared to quantifying the current performance of all professional astronomers in Australia. We have trawled the staff web-pages of Australian Universities, Observatories and Research Organisations hosting professional astronomers, and identified 384 PhD-qualified, research-active, astronomers in the nation. 132 of these are not members of the Astronomical Society of Australia. Using the SAO/NASA Astrophysics Data System, we provide the three following common metrics based on publications in the first decade of the 21st century (2001-2010): h-index, author-normalised citation count and lead-author citation count. We additionally present a somewhat more inclusive analysis, applicable for many early-career researchers, that is based on publications from 2006-2010. Histograms and percentiles, plus top-performer lists, are presented for each category. Finally, building on Hirsch's empirical equation, we find that the (10-year) h-index and (10-year) total citation count T can be approximated by the relation AS12011_IE1.gif for h>~5.

    Background Interlocks reduce driving-under-the-influence (DUI) recidivism by 64%, but offenders resist installing them, preferring to risk driving while their driver’s licenses are revoked. One method of motivating offenders to install an interlock is require it for reinstatement of their driver’s license. This report updates an earlier evaluation of the administrative reinstatement interlock program (ARIP) procedure implemented in Florida in 2002. Method Driver records and interlock program records covering 120,000 DUI offenders were followed over 10 years. The flow through the sanction system—conviction, reinstatement, interlock program, and postinterlock period—is described. Logistical regression was used to identify the characteristics of offenders who installed interlocks, and survival analysis was used to evaluate the recidivism of offenders in the various stages in the ARIP. Results At any given time, approximately one third of the convicted offenders were serving their license-revocation periods. Half of the offenders who completed their revocation periods remain unqualified for reinstatement because they do not fulfill other requirements. ARIP offenders who do qualify for reinstatement and install interlocks have lower recidivism rates while the devices are on their vehicles. Conclusions After 10 years, Florida’s ARIP is a mature system that succeeds in forcing all offenders in the program who qualify for reinstatement to install an interlock for at least 6 months. However, half of all offenders who complete their mandatory revocation period are either unable to, or choose not to, qualify for reinstatement. PMID:23442206

    Relation of antiplatelet therapy (APT) discontinuation with the risk of serious cardiovascular events has not been fully addressed yet. This study is aimed to evaluate the risk of ischemic event after APT discontinuation based on long-term APT status of large cohort. In the CREDO-Kyoto Registry Cohort-2 enrolling 15939 consecutive patients undergoing first coronary revascularization, 10470 patients underwent percutaneous coronary intervention either with bare-metal stents (BMS) only (N=5392) or sirolimus-eluting stents (SES) only (N=5078). Proportions of patients taking dual-APT were 67.3% versus 33.4% at 1-year, and 48.7% versus 24.3% at 5-year in the SES and BMS strata, respectively. We evaluated daily APT status (dual-, single- and no-APT) and linked the adverse events to the APT status just 1-day before the events. No-APT as compared with dual- or single-APT was associated with significantly higher risk for stent thrombosis (ST) beyond 1-month after SES implantation (cumulative incidence rates beyond 1-month: 1.23 versus 0.15/0.29, P<0.001/P<0.001), while higher risk of no-APT for ST was evident only until 6-month after BMS implantation (incidence rates between 1- and 6-month: 8.43 versus 0.71/1.20, P<0.001/P<0.001, and cumulative incidence rates beyond 6-month: 0.31 versus 0.11/0.08, P=0.16/P=0.08). No-APT as compared with dual- or single-APT was also associated with significantly higher risk for spontaneous myocardial infarction (MI) and stroke regardless of the types of stents implanted. Single-APT as compared with dual-APT was not associated with higher risk for serious adverse events, except for the marginally higher risk for ST in the SES stratum. In conclusion, discontinuation of both aspirin and thienopyridines was associated with increased risk for serious cardiovascular events including ST, spontaneous MI and stroke beyond 1-month after coronary stenting.

    BACKGROUND Psoriasis is a chronic inflammatory disease and its pathogenesis involves an interaction between genetic, environmental, and immunological factors. Recent studies have suggested that the chronic inflammatory nature of psoriasis may predispose to an association with other inflammatory diseases, especially cardiovascular diseases and metabolic disorders. OBJECTIVES To describe the demographic, clinical, epidemiological, and laboratory characteristics of a sample of psoriasis patients; to assess the prevalence of cardiovascular comorbidities in this group of patients; and to identify the cardiovascular risk profile using the Framingham risk score. METHODS We conducted a cross-sectional study involving the assessment of 190 patients. Participants underwent history and physical examination. They also completed a specific questionnaire about epidemiological data, past medical history, and comorbidities. The cardiovascular risk profile was calculated using the Framingham risk score. RESULTS Patients' mean age was 51.5 ± 14 years, and the predominant clinical presentation was plaque psoriasis (78.4%). We found an increased prevalence of systemic hypertension, type 2 diabetes, metabolic syndrome, and obesity. Increased waist circumference was also found in addition to a considerable prevalence of depression, smoking, and regular alcohol intake. Patients' cardiovascular risk was high according to the Framingham risk score, and 47.2% of patients had moderate or high risk of fatal and non-fatal coronary events in 10 years. CONCLUSIONS Patients had high prevalence of cardiovascular comorbidities, and high cardiovascular risk according to the Framingham risk score. Further epidemiological studies are needed in Brazil for validation of our results. PMID:25184912

    The multicenter Japanese-Assessment of Cardiac Events and Survival Study by Quantitative Gated SPECT (J-ACCESS), which involved 117 institutions and 4,629 patients, was the first attempt to quantify cardiac events and survival using stress-rest-gated single-photon emission computed tomography myocardial perfusion images (MPI) and QGS software in Japan. A 3-year follow-up study showed a relatively lower incidence of hard events than in the USA and some European countries, but a similar role of perfusion and left ventricular (LV) function. A low event risk with normal MPI and a higher incidence of major cardiac events in patients with large perfusion defects and LV dysfunction were defined. MPI was useful even among patients with proven coronary artery stenosis. The association between diabetes and chronic kidney disease (CKD) was an important predictor of cardiac events and the risk was evaluated using new software and risk charts. Additional studies were extended to include asymptomatic diabetes (J-ACCESS 2) and CKD (J-ACCESS 3). Because risk estimation is linked to the national healthcare system and clinical practice, optimal risk stratification and guidance for therapeutic strategies are recommended.

    Obesity is an independent risk factor for recurrent events among patients with established coronary heart disease (CHD). The goal of the present study was to identify potential mechanisms underlying this association. We measured the waist-to-hip ratio and body mass index in 979 outpatients with stable CHD and followed them for a mean of 4.9 years. We used proportional hazards models to evaluate the extent to which the association of obesity with subsequent heart failure (HF) hospitalization or cardiovascular (CV) events (myocardial infarction, stroke, or CHD death) was explained by baseline co-morbidities, cardiac disease severity, inflammation, insulin resistance, neurohormones and adipokines. Of the 979 participants, 128 (13%) were hospitalized for HF and 152 (16%) developed a CV event. Each standard deviation (SD) increase in the waist-to-hip ratio was associated with a 30% increased risk of HF hospitalization (unadjusted hazard ratio [HR] 1.3, 95% confidence interval [CI] 1.1 to 1.6). This association was not attenuated after adjustment for potential mediators (HR 1.6, 95% CI 1.2 to 2.1). Likewise, each SD increase in the waist-to-hip ratio was associated with a 20% greater risk of CV events (unadjusted HR 1.2, 95% CI 1.0 to 1.4), and this remained unchanged after adjustment for potential mediators (adjusted HR 1.3, 95% CI 1.0 to 1.5). The body mass index was not associated with the risk of HF or CV events. In conclusion, abdominal obesity is an independent predictor of HF hospitalization and recurrent CV events in patients with stable CHD. This association does not appear to be mediated by co-morbid conditions, cardiac disease severity, insulin resistance, inflammation, neurohormones, or adipokines.

    Parathyroid carcinoma (PC) is a rare cause of hypercalcaemia in children. Only 7 cases of PC have been reported so far in the world journal. The authors report the 8th case of parathyroid carcinoma in children less than 16 years of age. A 10 year old girl presented with difficulty in walking, dorsiflexion and ulnar deviation of both wrist joints and occasional pain in the central abdomen of about two years duration. Biochemical investigations revealed serum calcium 12.2 mg/dL (normal 9-11 mg/dL), serum alkaline phosphate 4992 U/L (normal 50-136 U/L), PTH (parathyroid hormone) 2217 pg/ml (normal 9-80 pg/ml). Parathyroid scintigraphy localized the lesion in the left parathyroid gland. X-ray showed bilateral coxa vera, genu valgus deformity and multiple stress fractures in both wrist joints. Histopathology confirmed PC with capsular and vascular invasion.

    In order to examine whether plasma samples may be used for steroid analysis after long periods of storage, cortisol, testosterone, oestrone and oestradiol were remeasured in samples, which had been analysed 1.3-10.8 years earlier. The method for the measurement of these steroids was unchanged over this period. The results demonstrate that at a temperature of -25 degrees C steroids remained stable. Only cortisol and testosterone concentrations showed a small, insignificant decrease (6-9%) after 3 to 4 years of storage. These differences are well within the range of the precision of the method (interassay variation), which over a period of 11 years was 9.4%, 8.0%, 10.0% and 9.5% for cortisol, testosterone, oestrone and oestradiol, respectively. It is concluded that steroid hormones in human plasma are stable in our laboratory, and that they might be analysed even after more than 10 years of storage at -25 degrees C. PMID:3831227

    Located near the boundary of the India, Pacific, and Eurasia plates, the Chinese continent is characterized by complex tectonics and high seismicity. Since the Sino-U.S. cooperative China Digital Seismograph Network (CDSN) began operating 10 years ago, it has played an active role in studying the seismology of China.Studies of the lithospheric structure and earthquake sources using digital seismic data are highly important in the study of geodynamics and the reduction of seismic disasters. Using the CDSN data, extensive studies were carried out by seismologists both in China and abroad. The studies investigated the lithospheric structure, seismic anisotropy within the upper mantle, and inversion of regional centroid moment tensors (RCMTs) of moderate to strong earthquakes. Earthquake sources were imaged based on broadband digital waveform analysis. As a result, over 100 papers have been published in China and abroad since 1990.

    Early Class III malocclusion treatment may not have long-term stability due to mandibular growth. Although some features of this malocclusion point to a better prognosis, it is practically impossible for the orthodontist to foresee cases that require new intervention. Many patients need retreatment, whether compensatory or orthodontic-surgical. The present study reports the case of a Class III patient treated at the end of the mixed dentition with the use of a face mask followed by conventional fixed appliances. The case remains stable 10 years after treatment completion. It was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) as a requirement for the title of certified by the BBO. PMID:25715726

    Scurvy, or hypovitaminosis C, is an uncommon condition that exists today primarily within certain unique populations-particularly the elderly subjects, patients with neurodevelopmental disabilities or psychiatric illnesses, or others with unusual dietary habits. Vitamin C is an essential nutrient in the human body, and is important in synthesizing collagen factor whose faulty production is responsible for most of the clinical manifestations of scurvy. These clinical manifestations can include dystrophic or corkscrew hairs, gingival hyperplasia, and weakened blood vessel walls, causing bleeding in the skin, joints, and other organs. Although rare in the Unites States, the presence of scurvy should not be forgotten because of its presence among susceptible populations. Moreover, with its diagnosis, treatment and cure is one of the simplest in modern medicine. We report a case of scurvy in a 10-year-old autistic child.

    The New Jersey DOE has drafted a 10-year master plan aimed at expanding state-wide conservation measures and encouraging the development of more than 2000 MW of cogenerated electricity through a combination of tax incentive and financial assistance programs. Although the plan deals with all sectors of energy use, the focus is on reducing industrial fuel and power costs. The incentives include a five-year exemption of new cogeneration facilities from property taxes, new buy-back rates equal to full avoided costs, and utility tariffs that allow the wheeling of cogenerated power. Part of the relicensing of casino-hotels could be a requirement for investigating the feasibility of installing a cogeneration system.

Over the past 10 years, the American Society for Parenteral and Enteral Nutrition and others have responded to the action call. A "state of the trichotomy" reveals that while much has been achieved, differences in all 3 aspects will continue to exist due to their dynamic and ever-changing states. The technology arena has made it possible to increase the delivery of nutrition support in alternative settings with the use of telemedicine and social media. Critical/crucial conversations and earlier declarations of individual wishes for care and treatment while having decision-making capacity have been enhanced with the focus on patient-centered and family-centered care. The definition of death as brain death has been challenged in at least one instance. Conflicts between the state's interests and the individual's interests have added to recent legal controversies. Notwithstanding the progress made over the past 10 years, several challenges remain. The future challenges presented by the Troubling Trichotomy can be best confronted if we ACT-Accountability, Communication, and Teamwork.

    BACKGROUND Numerous studies have been conducted on the predictive effects of high-sensitivity C-reactive protein (hs-CRP) on cardiovascular events. Few studies have been conducted to investigate the effects of adiponectin for the prediction of the incident of cardiovascular events in the Middle East area. This study compared the predictive effect of hs-CRP and adiponectin on healthy volunteers for the prediction of cerebrovascular disease (CVD). METHODS This nested case-control in original Isfahan Cohort Study (ICS) was conducted from 2001 to 2011. Participants were selected from ICS. The case group included participants with CVD while the control group included participants without CVD. The level of hs-CRP and adiponectin was measured in the blood samples collected in the year 2007. Thereafter, the statistical analyses were performed to determine the predictive value of hs-CRP and adiponectin in CVD prediction. RESULTS The results showed that before the elimination of diabetes effect; there was a significant difference between the two groups, in terms of the mean of adiponectin (P = 0.019) and no significant difference was observed in hs-CRP levels (P = 0.673). However, after eliminating the factor of diabetes, there was no significant difference between the case and control groups in adiponectin and hs-CRP levels (P = 0.184, P = 0.946). The results showed that the odds ratio (OR) of the adiponectin level was 0.879 [95% confidence interval (CI): 0.719-1.075, P = 0.210] while the OR of hs-CRP was 1.045 (95% CI: 0.922-1.185, P = 0.491). Furthermore, it was shown that after adjustment for age, sex, and diabetes; the OR of adiponectine was 0.875 (95% CI: 0.701-1.091, P = 0.235) and that of hs-CRP was 1.068 (95% CI: 0.935-1.219, P = 0.333). CONCLUSION The results show that adiponectin and hs-CRP cannot be predictors for cardiovascular events in a healthy population. Risk factors such as diabetes limit the use of adiponectin as a CVD predictor. PMID:27752270

    Study Objectives: To investigate the relationship between sleep duration and insomnia severity and the risk of all-cause death and cardiovascular disease (CVD) events Design: Prospective cohort study Setting: Community-based Participants: A total of 3,430 adults aged 35 years or older Intervention: None Measurements and Results: During a median 15.9 year (interquartile range, 13.1 to 16.9) follow-up period, 420 cases developed cardiovascular disease and 901 cases died. A U-shape association between sleep duration and all-cause death was found: the age and gender-adjusted relative risks (95% confidence interval [CI]) of all-cause death (with 7 h of daily sleep being considered for the reference group) for individuals reporting ≤ 5 h, 6 h, 8 h, and ≥ 9 h were 1.15 (0.91–1.45), 1.02 (0.85–1.25), 1.05 (0.88–1.27), and 1.43 (1.16–1.75); P for trend, 0.019. However, the relationship between sleep duration and risk of CVD were linear. The multivariate-adjusted relative risk (95% CI) for all-cause death (using individuals without insomnia) were 1.02 (0.86–1.20) for occasional insomnia, 1.15 (0.92–1.42) for frequent insomnia, and 1.70 (1.16–2.49) for nearly everyday insomnia (P for trend, 0.028). The multivariate adjusted relative risk (95% CI) was 2.53 (1.71–3.76) for all-cause death and 2.07 (1.11–3.85) for CVD rate in participants sleeping ≥9 h and for those with frequent insomnia. Conclusions: Sleep duration and insomnia severity were associated with all-cause death and CVD events among ethnic Chinese in Taiwan. Our data indicate that an optimal sleep duration (7–8 h) predicted fewer deaths. Citation: Chien K; Chen P; Hsu H; Su T; Sung F; Chen M; Lee Y.

    Objective To investigate the impact of smoking and smoking cessation on cardiovascular mortality, acute coronary events, and stroke events in people aged 60 and older, and to calculate and report risk advancement periods for cardiovascular mortality in addition to traditional epidemiological relative risk measures. Design Individual participant meta-analysis using data from 25 cohorts participating in the CHANCES consortium. Data were harmonised, analysed separately employing Cox proportional hazard regression models, and combined by meta-analysis. Results Overall, 503 905 participants aged 60 and older were included in this study, of whom 37 952 died from cardiovascular disease. Random effects meta-analysis of the association of smoking status with cardiovascular mortality yielded a summary hazard ratio of 2.07 (95% CI 1.82 to 2.36) for current smokers and 1.37 (1.25 to 1.49) for former smokers compared with never smokers. Corresponding summary estimates for risk advancement periods were 5.50 years (4.25 to 6.75) for current smokers and 2.16 years (1.38 to 2.39) for former smokers. The excess risk in smokers increased with cigarette consumption in a dose-response manner, and decreased continuously with time since smoking cessation in former smokers. Relative risk estimates for acute coronary events and for stroke events were somewhat lower than for cardiovascular mortality, but patterns were similar. Conclusions Our study corroborates and expands evidence from previous studies in showing that smoking is a strong independent risk factor of cardiovascular events and mortality even at older age, advancing cardiovascular mortality by more than five years, and demonstrating that smoking cessation in these age groups is still beneficial in reducing the excess risk.

    This collaborative study is based on the analysis and comparison of results of coordinated experimental investigations conducted in Bulgaria and Azerbaijan for revealing a possible influence of solar activity changes and related geomagnetic activity variations on the human cardio-vascular state. Arterial blood pressure and heart rate of 86 healthy volunteers were measured on working days during a period of comparatively high solar and geomagnetic activity (2799 measurements in autumn 2001 and spring 2002) in Sofia. Daily experimental investigations of parameters of cardio-vascular health state were performed in Azerbaijan with a permanent group of examined persons. Heart rate and electrocardiograms were digitally registered (in total 1532 records) for seven functionally healthy persons on working days and Saturdays, in the Laboratory of Heliobiology at the Medical Center INAM in Baku, from 15.07.2006 to 13.11.2007. Obtained digital recordings were subjected to medical, statistical and spectral analyses. Special attention was paid to effects of solar extreme events, particularly those of November 2001 and December 2006. The statistical method of the analysis of variance (ANOVA) and post hoc analysis were applied to check the significance of the influence of geomagnetic activity on the cardio-vascular parameters under consideration. Results revealed statistically significant increments for the mean systolic and diastolic blood pressure values of the group with geomagnetic activity increase. Arterial blood pressure values started increasing two days prior to geomagnetic storms and kept their high values up to two days after the storms. Heart rate reaction was ambiguous and not significant for healthy persons examined (for both groups) under conditions with geomagnetic activity changes. It is concluded that heart rate for healthy persons at middle latitudes can be considered as a more stable physiological parameter which is not so sensitive to environmental changes

    Sparse data are available on presentation and management of acute coronary syndromes (ACS), including unstable angina and non-ST- and ST-elevation myocardial infarction, among persons with haemophilia (PWH). The aim of this study was to determine demographics, bleeding disorder characteristics, cardiovascular risk factors (CRFs), interventions, haemostatic protocol, revascularization outcomes and complications among PWH with ACS. Members of an international consortium comprising >2000 adult PWH retrospectively completed case report forms for episodes of ACS in a >10-year follow-up period (2003-2013). Twenty ACS episodes occurred among 19 patients [rate, 0.8% (95% CI 0.4, 1.2)]. Seven patients (37%) were aged <50 years; 10 (53%) had ≥3 CRFs. In 5/20 episodes (25%), the initial ACS management protocol was altered because of the bleeding disorder. None of the eight patients with severe haemophilia underwent coronary artery bypass grafting (CABG), compared with 54.5% of patients with non-severe disease (P = 0.02). Revascularization with percutaneous coronary intervention (PCI) or CABG was rated successful in 13/13 cases, with no excessive bleeding during initial management. During chronic exposure to antiplatelet agents, secondary haemophilia prophylaxis was more prevalent in patients with severe haemophilia compared with non-severe haemophilia (85.7% vs. 30%, P = 0.05). No ACS-related deaths occurred during initial management, but one patient with severe haemophilia A died of undetermined cause 36 months after the ACS event while on aspirin therapy. ACS occurs even among relatively younger PWH, typically in association with multiple CRFs. Revascularization with PCI/CABG is feasible, and antiplatelet agents plus secondary prophylaxis appears to be well tolerated in selected PWH with ACS.

    To compare the predicative ability of SYNTAX (Synergy between PCI with Taxus and Cardiac Surgery) and clinical SYNTAX scores for major adverse cardiac events (MACEs) after stent implantation in patients with coronary artery disease (CAD). Studies were identified by electronic and manual searches. Twenty-six studies were included in the meta-analysis. The pooled C-statistics of SYNTAX score for 1- and 5-year all-cause mortality (ACM) were 0.65 (95% confidence interval [CI]: 0.61-0.68) and 0.62 (95% CI: 0.59-0.65), respectively, with weak heterogeneity. The 1- and 5-year ACM pooled C-statistics for clinical SYNTAX scores were significantly higher at 0.77 and 0.71, respectively (Ps < .05). Both scoring systems predicted 1- and 5-year MACE equally well. The pooled risk ratio of the SYNTAX score for predicting 1-year ACM per unit was 1.04 (95% CI: 1.03-1.05). Calibration analysis indicated SYNTAX scores overestimated the risk of major adverse cardiac and cerebrovascular events in each risk stratum. The SYNTAX score demonstrated minimal discrimination in predicting 1- or 5-year adverse cardiovascular events after percutaneous coronary intervention in patients with CAD. The clinical SYNTAX score could further improve the predictive capability for ACM but not MACE.

Few outlets were able to accommodate and quickly share that amount of information as well as the Internet. To honor the 10-year anniversary of the launch of Terra, we would like to highlight the education and outreach efforts of the Terra mission on the Internet and its reach to the science attentive public. The Internet or web has been the primary way of delivering Terra content to different groups- from formal and informal education to general public outreach. Through the years, many different web-based projects have been developed, and they were of service to a growing population of the science attentive public. One of Terra’s original EPO activities was the Earth Observatory. It was initially dedicated to telling the remote sensing story of Terra, but quickly grew to include science and imagery from other sensors. The web site allowed for collaboration across NASA centers, universities and other organizations by exchanging and sharing of story ideas, news and images. The award winning Earth Observatory helped pave the way for the more recently funded development of the Climate Change website. With its specific focus on climate change studies, once again, Terra stories and images are shared with an even more specific audience base. During the last 10 years, Terra as a mission has captured the imagination of the public through its visually stunning and artistically arresting images. With its five instruments of complementary but unique capabilities, the mission gave the world not just pretty pictures, but scientific data-based images. The world was able to see from space everything from calving icebergs to volcanic eruption plumes and the eye of a

    Objective Hyperglycaemic crisis was associated with significant intrahospital morbidity and mortality. However, the association between hyperglycaemic crisis and long-term cardiovascular outcomes remained unknown. This study aimed to investigate the association between hyperglycaemic crisis and subsequent long-term major adverse cardiovascular events (MACEs). Participants and methods This population-based cohort study was conducted using data from Taiwan's National Health Insurance Research Database for the period of 1996–2012. A total of 2171 diabetic patients with hyperglycaemic crisis fit the inclusion criteria. Propensity score matching was used to match the baseline characteristics of the study cohort to construct a comparison cohort which comprised 8684 diabetic patients without hyperglycaemic crisis. The risk of long-term MACEs was compared between the two cohorts. Results Six hundred and seventy-six MACEs occurred in the study cohort and the event rate was higher than that in the comparison cohort (31.1% vs 24.1%, p<0.001). Patients with hyperglycaemic crisis were associated with a higher risk of long-term MACEs even after adjusting for all baseline characteristics and medications (adjusted HR=1.76, 95% CI 1.62 to 1.92, p<0.001). Acute myocardial infarction had the highest adjusted HR (adjusted HR=2.19, 95% CI 1.75 to 2.75, p<0.001) in the four types of MACEs, followed by congestive heart failure (adjusted HR=1.97, 95% CI 1.70 to 2.28, p<0.001). Younger patients with hyperglycaemic crisis had a higher risk of MACEs than older patients (adjusted HR=2.69 for patients aged 20–39 years vs adjusted HR=1.58 for patients aged >65 years). Conclusions Hyperglycaemic crisis was significantly associated with long-term MACEs, especially in the young population. Further prospective longitudinal study should be conducted for validation.

    Davis, George E

    2010-03-01

    This review addresses new concepts related to the importance of how cells within the cardiovascular system respond to matricryptic sites generated from the extracellular matrix (ECM) following tissue injury. A model is presented whereby matricryptic sites exposed from the ECM result in activation of multiple cell surface receptors including integrins, scavenger receptors, and toll-like receptors which together are hypothesized to coactivate downstream signaling pathways which alter cell behaviors following tissue injury. Of great interest are the relationships between matricryptic fragments of ECM called matricryptins and other stimuli that activate cells during injury states such as released components from cells (DNA, RNA, cytoskeletal components such as actin) or products from infectious agents in innate immunity responses. These types of cell activating molecules, which are composed of repeating molecular elements, are known to interact with pattern recognition receptors that (i) are expressed from cell surfaces, (ii) are released from cells following tissue injury, or (iii) circulate as components of plasma. Thus, cell recognition of matricryptic sites from the ECM appears to be an important component of a broad cell and tissue sensory system to detect and respond to environmental cues generated following varied types of tissue injury.

    NASA's Chandra X-ray Observatory, originally envisioned as a 5-year mission, was deployed into an elliptical orbit around Earth 10 years ago, on 23 July 1999. The most powerful X-ray telescope yet, Chandra has provided a peak into the high-energy universe and has independently confirmed the existence of dark energy. Martin Weisskopf, Chandra project scientist at NASA's Marshall Space Flight Center, Huntsville, Ala., said discoveries made possible by the observatory “have made dramatic changes to our understanding of the universe and its constituents.” “The Great Observatories program—of which Chandra is a major part—shows how astronomers need as many tools as possible to tackle the big questions out there,” said Ed Weiler, associate administrator of NASA's Science Mission Directorate at NASA Headquarters in Washington. The Hubble Space Telescope, Compton Gamma Ray Observatory, and Spitzer Space Telescope are NASA's other Great Observatories.

    This article describes the first 10 years of the implementation of Circles of Support and Accountability (Circles) in the management of sexual offenders in South-East England by Circles South East (CSE). The Circles of 71 core members are reviewed in detail, with reference to demographic data, offense and sentencing histories, risk assessment data, and considerations regarding Multi-Agency Public Protection Arrangements. A group of 71 comparison subjects who were referred to CSE and deemed suitable for but did not receive the service was identified. Follow-up behaviors of both groups are examined (including all forms of reconviction, breach of orders, and prison recall). Over a comparable follow-up period of 55 months, the incidence of violent and contact sexual reconviction in the comparison group was significantly higher than for the Circles cohort. Comparisons are made between expected and actual levels of sexual reconviction, with the Circles cohort showing lower than expected rate of sexual reconviction but not to a statistically significant degree.

    The purpose of this study was to record and evaluate the causes and the magnitude of the fatal burn injuries retrospectively. An analysis of autopsy records revealed 19.4% cases of burn injuries amongst the total autopsies done over 10years period (1993-2002) in the mortuary of the department of Forensic Medicine of Kasturba medical College, Manipal. The majority of deaths (78.5%) occurred between 11 and 40years of age group with preponderance of females (74.8%). The flame burns were seen in 94.1% of the victims followed by scalds and electrical burns in 2.8% and 2.5% cases, respectively. The majority of burn incidents were accidental (75.8%) in nature followed by suicidal (11.5%) and homicidal (3.1%) deaths. The percentage of burn (TBSA) over 40% were observed in most of the cases (92.5%). The majority of deaths occurred within a week (69.87%) and most the victims died because of septicemia (50.9%).

    Background Alopecia areata (AA) is an organ-specific autoimmune disease that typically occurs in young adults. AA in the elderly is relatively rare, thus little data have been reported. Objective This study aimed to understand the clinical characteristics of AA in the elderly. Methods We performed a 10-year retrospective study of AA in the elderly who visited our dermatologic clinic from January 2002 to December 2011. A clinical review of medical records and telephone interviews were performed by two dermatologists. Results Among 1,761 patients with newly diagnosed AA, 61 (3.5%) were older than 60 years at the first visit. Among those who completed a telephone interview, 74.3% (26/35) had less than 50% of scalp-localized hair loss. There was no association between the extent of AA and hair graying (p=0.679). Favorable therapeutic response was observed in 62.9% (22/35) of cases. Conclusion AA in the elderly shows mild disease severity and favorable treatment response. There is no association between graying and the extent of AA. However, the influence of aging on the pathogenesis of AA in the elderly deserves further investigation. PMID:26273157

    A 10-year experiment tested for variation in competition intensity over time in a natural grassland at the northern edge of the Great Plains. Growing-season precipitation varied fivefold during the study. All ecosystem-level variables varied significantly among years, and most covaried in expected ways. The covers of all common grasses possessing the C3 photosynthetic pathway varied significantly among years; in contrast, all common species with traits associated with drought tolerance (a C4 grass, a lichen, a spikemoss, and a subshrub) did not vary. Annual transplant experiments measured the competitive effects of neighbors on the growth of individuals of the native grass Bouteloua gracilis. A significant interaction between year and competition showed that competition intensity varied among years. The size of this effect, however, was small (eta2 = 0.074) relative to the size of the direct effect of competition (eta2 = 0.20) or the year in which the experiment was conducted (eta2 = 0.51). Further, competition intensity was not significantly related to any variable describing standing crop or resources, or species richness. Species richness was highest in years with high precipitation, standing crop, and individual growth, due to the recruitment of rare species that were absent from dry years. In summary, variation in competition intensity was statistically significant but had small effects relative to the direct effects of climate. PMID:18229830

    International Space Company "Kosmotras" (ISC "Kosmotras") was founded in 1997 by the decisions of the Russian Aviation and Space Agency and the National Space Agency of Ukraine. It incorporated leading space industries of Russia and Ukraine. The first Launch Contract was signed in 1998 and in 1999 Dnepr launch vehicle carrying SSTL UoSAT-12 spacecraft (SC) was launched. During 10 years of its activity in the launch services market, ISC "Kosmotras" has exercised 9 successful space launches as a result of which 39 SC were placed into orbit. The flight reliability of Dnepr Launch Vehicle (LV) is estimated as 0.97. Three configurations of Space Head Module (SHM) are available for payload accommodation: a standard- size SHM for multiple small satellite missions (cluster launches); a standard-size SHM for mid-size satellites; an extended SHM for large-size satellite. ISC "Kosmotras" exercises space launches from two launch bases: Baikonur Cosmodrome (Kazakhstan) and Yasny Launch Base (Russia). This allows flexible planning of launch operations.

  11. Dissociative recombination of H3+: 10 years in retrospect

    The dissociative recombination of has been an intriguing problem for more than half a century. The early experiments on during the first 20 years were carried out without mass analysis in decaying plasma afterglows, and thus the measured rates pertained to an uncontrolled mixture of and impurity ions. When mass analysis was used, the rate coefficient was determined to be an uneventful value of about 10−7 cm3 s−1, a very common rate coefficient for many molecular ions. But this was not the end of the story, not even the beginning of the end; it marked only the end of the beginning. The story I will tell in this article started about 10 years ago, when the dissociative recombination of was approaching its deepest crisis. Today, owing to an extensive experimental and theoretical effort, the state of affairs has reached a historically unique level of harmony, although there still remains many things to sort out.

    Introduction According to the literature, the increased recreational use of the snowmobile has resulted in an increasing number of musculoskeletal injuries. We wished to examine whether previously described risk factors continue to be associated with snowmobile trauma and to identify previously unrecognized risks and specific patterns of injury. Methods We carried out a chart review of all snowmobile-related injuries over a 10-year period at the Health Sciences Centre in Winnipeg, the only level 1 trauma centre serving the Province of Manitoba, with particular attention to the risk factors of suboptimal lighting, excessive speed and alcohol consumption. Results We identified 480 injuries in 294 patients, and 81 (27.6%) of these patients died. Collisions accounted for 72% of the injury mechanisms. Of the injuries sustained, 31% occurred on roads. Excessive speed was a risk factor in 54% of patients, suboptimal lighting in 86% and a blood alcohol level greater than 0.08 in 70%. Musculoskeletal injuries accounted for 57% of those recorded. There were also brachial plexus injuries (3%) and knee dislocations (2%). To our knowledge, this is the largest study detailing injury associated with recreational use of snowmobiles in Canada. Conclusions Because snowmobile trauma is caused principally by human errors, it is potentially preventable. Efforts aimed at prevention must focus on the driver, who controls the common risk factors. The danger of snowmobiling while intoxicated must be emphasized. Trail-side monitoring is likely to be ineffective, as the majority of accidents do not occur on designated snowmobile trails.

    We use the 10-year aerosol data record from the Multi-angle Imaging SpectroRadiometer (MISR) aboard the Terra satellite to investigate climatological linkages between the dust source activities, mid-range, and long-range transport of Asian dust. The inter-annual and seasonal variability of Asian dust loadings and properties as retrieved by MISR at selected regions along the transport routes was investigated. In particular, we examine the Taklamakan and East and Central Gobi regions (dust sources), South Korea and Japan regions (mid-range transport), and the North Pacific region along the northwestern U.S. coast (long-range transport). To avoid the gridding and averaging effects in Level 3 products, we use the Level 2 MISR data. Within each selected region, the analysis was performed to examine the multi-annual mean and variability of the aerosol optical depth and particle nonsphericity as well as time-lag correlation between the regions, taking into account the effects of MISR sampling and cloud coverage. The results will be presented and interpreted in the context of atmospheric dynamics variability, including variability of meteorological regimes in dust sources and the large-scale atmospheric circulation features controlling the trans-Pacific transport of Asian dust.

    Proteasome inhibition has emerged as an important therapeutic strategy in multiple myeloma (MM). Since the publication of the first phase 1 trials of bortezomib 10 years ago, this first-in-class proteasome inhibitor (PI) has contributed substantially to the observed improvement in survival in MM patients over the past decade. Although first approved as a single agent in the relapsed setting, bortezomib is now predominantly used in combination regimens. Furthermore, the standard twice-weekly schedule may be replaced by weekly infusion, especially when bortezomib is used as part of combination regimens in frontline therapy. Indeed, bortezomib is an established component of induction therapy for patients eligible or ineligible for autologous stem cell transplantation. Bortezomib has also been incorporated into conditioning regimens before autologous stem cell transplantation, as well as into post-ASCT consolidation therapy, and in the maintenance setting. In addition, a new route of bortezomib administration, subcutaneous infusion, has recently been approved. Recently, several new agents have been introduced into the clinic, including carfilzomib, marizomib, and MLN9708, and trials investigating these “second-generation” PIs in patients with relapsed/refractory MMs have demonstrated positive results. This review provides an overview of the role of PIs in the treatment of MM, focusing on developments over the past decade. PMID:22645181

    In the last 15 years, extensive work on the Cryptophlebia leucotreta granulovirus (CrleGV) has been conducted in South Africa, initially in the laboratory, but subsequently also in the field. This culminated in the registration of the first CrleGV-based biopesticide in 2004 (hence, the 10 years of commercial use in the field) and the second one three years later. Since 2000, more than 50 field trials have been conducted with CrleGV against the false codling moth, Thaumatotibia leucotreta, on citrus in South Africa. In a representative sample of 13 field trials reported over this period, efficacy (measured by reduction in larval infestation of fruit) ranged between 30% and 92%. Efficacy was shown to persist at a level of 70% for up to 17 weeks after application of CrleGV. This only occurred where the virus was applied in blocks rather than to single trees. The addition of molasses substantially and sometimes significantly enhanced efficacy. It was also established that CrleGV should not be applied at less than ~2 × 1013 OBs per ha in order to avoid compromised efficacy. As CrleGV-based products were shown to be at least as effective as chemical alternatives, persistent and compatible with natural enemies, their use is recommended within an integrated program for control of T. leucotreta on citrus and other crops.

    Tularaemia has been mandatorily notifiable in France since October 2002. The surveillance aims to detect early any infection possibly due to bioterrorism and to follow up disease trends. We report the results of national surveillance from 2002 to 2012. A case is defined as a patient with clinical presentation suggestive of tularaemia and biological confirmation of infection or an epidemiological link with a biologically confirmed case. Clinical, biological and epidemiological data are collected using a standardised notification form. From 2002 to 2012, 433 cases were notified, with a median age of 49 years (range 2 to 95 years) and a male–female sex ratio of 1.8. Most frequent clinical presentations were glandular tularaemia (n=200; 46%) and ulceroglandular tularaemia (n=113; 26%). Most frequent at-risk exposures were handling hares (n=179; 41%) and outdoor leisure exposure to dust aerosols (n=217; 50%). Tick bites were reported by 82 patients (19%). Ten clusters (39 cases) were detected over the 10-year period, as well as a national outbreak during winter 2007/2008. The tularaemia surveillance system is able to detect small clusters as well as major outbreaks. Surveillance data show exposure to dust aerosols during outdoor leisure activities to be a major source of contamination in France.

    More than 10 years ago Haux et al. tried to answer the question how health care provision will look like in the year 2013. A follow-up workshop was held in Braunschweig, Germany, for 2 days in May, 2013, with 20 invited international experts in biomedical and health informatics. Among other things it had the objectives to discuss the suggested goals and measures of 2002 and how priorities on MI research in this context should be set from the viewpoint of today. The goals from 2002 are now as up-to-date as they were then. The experts stated that the three goals: "patient-centred recording and use of medical data for cooperative care"; "process-integrated decision support through current medical knowledge" and "comprehensive use of patient data for research and health care reporting" have not been reached yet and are still relevant. A new goal for ICT in health care should be the support of patient centred personalized (individual) medicine. MI as an academic discipline carries out research concerning tools that support health care professionals in their work. This research should be carried out without the pressure that it should lead to systems that are immediately and directly accepted in practice. PMID:24952607

    Background It is unclear whether coronary heart disease (CHD) risk factor exposure during early adulthood contributes to CHD risk later in life. Our objective was to analyze whether extent of early adult exposures to systolic and diastolic blood pressure (SBP, DBP) and low-and high-density lipoprotein cholesterol (LDL, HDL) are independent predictors of CHD events later in life. Methods and Findings We used all available measurements of SBP, DBP, LDL, and HDL collected over 40 years in the Framingham Offspring Study to estimate risk factor trajectories, starting at age 20 years, for all participants. Average early adult (age 20–39) exposure to each risk factor was then estimated, and used to predict CHD events (myocardial infarction or CHD death) after age 40, with adjustment for risk factor exposures later in life (age 40+). 4860 participants contributed an average of 6.3 risk factor measurements from in-person examinations and 24.5 years of follow-up after age 40, and 510 had a first CHD event. Early adult exposures to high SBP, DBP, LDL or low HDL were associated with 8- to 30-fold increases in later life CHD event rates, but were also strongly correlated with risk factor levels later in life. After adjustment for later life levels and other risk factors, early adult DBP and LDL remained strongly associated with later life risk. Compared with DBP≤70 mmHg, adjusted hazard ratios (HRs) were 2.1 (95% confidence interval: 0.8–5.7) for DBP = 71–80, 2.6 (0.9–7.2) for DBP = 81–90, and 3.6 (1.2–11) for DBP>90 (p-trend = 0.019). Compared with LDL≤100 mg/dl, adjusted HRs were 1.5 (0.9–2.6) for LDL = 101–130, 2.2 (1.2–4.0) for LDL = 131–160, and 2.4 (1.2–4.7) for LDL>160 (p-trend = 0.009). While current levels of SBP and HDL were also associated with CHD events, we did not detect an independent association with early adult exposure to either of these risk factors. Conclusions Using a mixed modeling approach to estimation of young adult exposures

    Background Dietary electrolytes influence blood pressure, but their effect on clinical outcomes remains to be established. We examined sodium and potassium intake in relation to cardiovascular disease (CVD) and mortality in an unselected older population. Methods A case–cohort analysis was performed in the Rotterdam Study among subjects aged 55 years and over, who were followed for 5 years. Baseline urinary samples were analyzed for sodium and potassium in 795 subjects who died, 206 with an incident myocardial infarction and 181 subjects with an incident stroke, and in 1,448 randomly selected subjects. For potassium, dietary data were additionally obtained by food-frequency questionnaire for 78% of the cohort. Results There was no consistent association of urinary sodium, potassium, or sodium/potassium ratio with CVD and all-cause mortality over the range of intakes observed in this population. Dietary potassium estimated by food frequency questionnaire, however, was associated with a lower risk of all-cause mortality in subjects initially free of CVD and hypertension (RR = 0.71 per standard deviation increase; 95% confidence interval: 0.51–1.00). We observed a significant positive association between urinary sodium/potassium ratio and all-cause mortality, but only in overweight subjects who were initially free of CVD and hypertension (RR = 1.19 (1.02–1.39) per unit). Conclusion The effect of sodium and potassium intake on CVD morbidity and mortality in Western societies remains to be established. PMID:17902026

    BACKGROUND The existence of stem/progenitor cells in the endometrium was postulated many years ago, but the first functional evidence was only published in 2004. The identification of rare epithelial and stromal populations of clonogenic cells in human endometrium has opened an active area of research on endometrial stem/progenitor cells in the subsequent 10 years. METHODS The published literature was searched using the PubMed database with the search terms ‘endometrial stem cells and menstrual blood stem cells' until December 2014. RESULTS Endometrial epithelial stem/progenitor cells have been identified as clonogenic cells in human and as label-retaining or CD44+ cells in mouse endometrium, but their characterization has been modest. In contrast, endometrial mesenchymal stem/stromal cells (MSCs) have been well characterized and show similar properties to bone marrow MSCs. Specific markers for their enrichment have been identified, CD146+PDGFRβ+ (platelet-derived growth factor receptor beta) and SUSD2+ (sushi domain containing-2), which detected their perivascular location and likely pericyte identity in endometrial basalis and functionalis vessels. Transcriptomics and secretomics of SUSD2+ cells confirm their perivascular phenotype. Stromal fibroblasts cultured from endometrial tissue or menstrual blood also have some MSC characteristics and demonstrate broad multilineage differentiation potential for mesodermal, endodermal and ectodermal lineages, indicating their plasticity. Side population (SP) cells are a mixed population, although predominantly vascular cells, which exhibit adult stem cell properties, including tissue reconstitution. There is some evidence that bone marrow cells contribute a small population of endometrial epithelial and stromal cells. The discovery of specific markers for endometrial stem/progenitor cells has enabled the examination of their role in endometrial proliferative disorders, including endometriosis, adenomyosis and Asherman

  1. Justification for Rhinoseptoplasty in Children – Our 10 Years Overview

    PubMed Central

    Kopacheva-Barsova, Gabriela; Nikolovski, Nikola

    2016-01-01

    BACKGROUND: Nasal septal surgery and rhinoplasty are controversial in children. Traditionally, an attitude of restraint has been employed by most surgeons till an empirical age of 16 to 18 years. This is to avoid the possible adverse effects that the growth spurts may have on the nose and midface region. AIM: The aim of this paper was to present the results of rhinoplasty in children in order to restore the anatomy and function or to promote normal development and outgrowth of the nose. MATERIAL AND METHODS: Ninety seven children aged 6-14, with severe nose deformities and breathing problems through the nose, were admitted for septo/rhinoplasty at the University Clinic for Ear, Nose and Throat, Faculty of Medicine, Ss Cyril and Methodius University of Skopje, Republic of Macedonia. At our Clinic, they have been observed and photographed (with parent permission) in the period of 10 years (2006-2016). The most frequent cause of these deformities was the nasal trauma in early childhood which was ignored or untreated. All of them rhino/septoplasty were indicated in accordance with the above-mentioned recommendations for rhino/septoplasty in early childhood and in adolescents. RESULTS: In 51 children and adolescents septoplasty were prepared. Mostly there was a group of younger children age from 6-10 (68%) and adolescents (32%). In the other 31 children and adolescents, septorhinoplasty was prepared. Mostly there were children older than 12 years old and adolescents (70%). Only 30% were younger than 12 years, of course with severe nasal breathing problems, nasal septal deformities and deformities of the nasal pyramid. CONCLUSION: The growth centres of the nose have to be avoided if possible; long-term nasal issues will theoretically be minimised. If the surgeon replaces it, the cartilage of the nose becomes straighter but still intact.

    In order to identify current trends in anaerobic bacteraemia, a 10-year retrospective study was performed in the University Hospital Brussel, Belgium. All clinically relevant bacteraemia detected from 2004 until 2013 were included. Medical records were reviewed in an attempt to define clinical parameters that might be associated with the occurrence of anaerobic bacteraemia. 437 of the isolated organisms causing anaerobic bacteraemia were thawed, subcultured and reanalyzed using matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF). There were an average of 33 cases of anaerobic bacteraemia per year during 2004-2008 compared to an average of 27 cases per year during 2009-2013 (P = 0.017), corresponding to a decrease by 19% between the first and the latter period. Also, the total number of cases of anaerobic bacteraemia per 100,000 patient days decreased from 17.3 in the period from 2004 to 2008 to 13.7 in the period 2009 to 2013 (P = 0.023). Additionally, the mean incidence of anaerobic bacteraemia decreased during the study period (1.27/1000 patients in 2004 vs. 0.94/1000 patients in 2013; P = 0.008). In contrast, the proportion of isolated anaerobic bacteraemia compared to the number of all bacteraemia remained stable at 5%. Bacteroides spp. and Parabacteroides spp. accounted for 47.1% of the anaerobes, followed by 14.4% Clostridium spp., 12.6% non-spore-forming Gram-positive rods, 10.5% anaerobic cocci, 8.2% Prevotella spp. and other Gram-negative rods and 7.1% Fusobacterium spp. The lower gastrointestinal tract (47%) and wound infections (10%) were the two most frequent sources for bacteraemia, with the origin remaining unknown in 62 cases (21%). The overall mortality rate was 14%. Further studies focusing on the antimicrobial susceptibility and demographic background of patients are needed to further objectify the currently observed trends.

The use of quantitative electroencephalography has been shown in a prospective study to be effective for predicting antidepressant treatment response. A novel antidepressant drug, agomelatine, has generated much controversy, and its development for the U.S. market was discontinued. A long awaited revised system for categorizing the safety of medications during pregnancy and lactation has finally been published by the Food and Drug Administration. Dextromethorphan/quinidine, eslicarbazepine acetate, levomilnacipran, and esketamine are recent examples of drugs that were developed based on the complex concepts of chirality and stereochemistry. Lisdexamfetamine, a stimulant drug, failed to show benefit as an augmentation therapy for the treatment of depression. The combination drug naltrexone/bupropion was finally approved as a therapy for obesity, after its cardiovascular safety was confirmed in a prospective premarketing study. Further development of the glucocorticoid receptor antagonist drug mifepristone as a treatment for psychotic depression was stopped based on a large negative trial, but the drug continues to be investigated for other potential psychiatric indications. These examples illustrate how the field of psychopharmacology continues to evolve.

Further development of the glucocorticoid receptor antagonist drug mifepristone as a treatment for psychotic depression was stopped based on a large negative trial, but the drug continues to be investigated for other potential psychiatric indications. These examples illustrate how the field of psychopharmacology continues to evolve. PMID:25622272

    We investigated the relation between overall atheroma burden and clinical events in the Providing Regional Observations to Study Predictors of Events in the Coronary Tree (PROSPECT) study. In PROSPECT, 660 patients (3,229 nonculprit lesions with a plaque burden ≥ 40% and complete intravascular ultrasound data) were divided into tertiles according to baseline percent atheroma volume (PAV: total plaque/vessel volume). Patients were followed for 3.4 years (median); major adverse cardiac events (MACE: death from cardiac causes, cardiac arrest, myocardial infarction, or rehospitalization because of unstable or progressive angina) were adjudicated to either culprit or nonculprit lesions. Compared with patients in low or intermediate PAV tertiles, patients in the high PAV tertile had the greatest prevalence of plaque rupture and radiofrequency thin-cap fibroatheroma (VH-TCFA) and the highest percentage of necrotic core volume; they were also more likely to have high-risk lesion characteristics: ≥ 1 lesion with minimal luminal area ≤ 4 mm(2), plaque burden >70%, and/or VH-TCFA. Three-year cumulative nonculprit lesion-related MACE was greater in the intermediate and high tertiles than in the low tertile (6.3% vs 14.7% vs 15.1%, low vs intermediate vs high tertiles, p = 0.009). On Cox multivariable analysis, insulin-dependent diabetes (hazard ratio [HR] 3.98, p = 0.002), PAV (HR 1.06, p = 0.03), and the presence of ≥1 VH-TCFA (HR 1.80, p = 0.02) were independent predictors of nonculprit MACE. In conclusion, increasing baseline overall atheroma burden was associated with more advanced, complex, and vulnerable intravascular ultrasound lesion morphology and independently predicted nonculprit lesion-related MACE in patients with acute coronary syndromes after successful culprit lesion intervention.

    Cardiovascular events (CE) occur most frequently in the morning hours in hypertensive subjects. We studied the association between the morning blood pressure (BP) surge and CE in prognosis of 10 normotensive and 32 well-controlled hypertensive elderly, in whom ambulatory BP monitoring was performed and who were followed prospectively for 5 years. The morning surge (MS) of BP was calculated as mean systolic BP during 2h after awakening--mean systolic BP during 1h that included the lowest sleep BP. During an average of 60 months, five CE occurred. When the patients were divided into two groups according to MS, those in the top terzile (MS group; MS> or =34 mmHg, n=14) had a higher prevalence of CE (5 versus 0, p=0.001) during the follow-up period, than the others (non-MS group; MS<34 mmHg, n=28). The logistic regression analysis showed the MS sleep-trough surge as predictive variable of CE (odds ratio, OR=0.794, p=0.022). In conclusion, in older normotensives and well-controlled hypertensives, a higher BP MS is associated with vascular risk independently of clinical and ambulatory BP. Reduction of the MS could thus be a therapeutic target for preventing vascular events also in non-hypertensive patients.

    Introduction Cardiovascular diseases are increasing in aging HIV-positive patients (HIV+). Impact of traditional cardiovascular risk factors, HIV-specific parameters and antiretroviral therapy (ART) on the incidence of cardiovascular events (CVE) and on the mortality rate are investigated in different HIV+ cohorts. Methods The HIV HEART (HIVH) study is an ongoing prospective observational cohort study in the German Ruhr area to assess the frequency and clinical course of cardiac disorders in 1481 HIV+ by standardized non-invasive cardiovascular screening. CVE were defined as diagnosed or documented myocardial infarction, coronary heart disease, arterial coronary intervention, stent implantation, bypass operation and stroke. Results 1481 HIV+ subjects (mean age: 49.3±10.7 years (y), female: 15.6%) were included. 130 CVE and 90 deaths were documented until the end of 7, 5 year follow-up of HIVH. Mean duration of the HIV-infection was 12.9±6.8 y. HIV+ were treated with ART on average for 8.6±6.8 y. According to the CDC classification of the HIV-infection, HIV+ were distributed over the clinical categories (A:34.6%; B:31.4% and C:33.9%) while more than the half had an advanced immunodeficiency (I:8.3%; II:41.1%; III:50.7%). Advanced clinical and immunological stages were significantly (p<0.001) associated with higher incidences of deaths (A:16.7%; B:26.7%; C:56.7% and I:6.7%; II:27.7%; III:65.6%) and CVE (A:17.7%; B:33.1%; C:49.2% and I:3.1%; II:32.3%; III:64.6%) but not with the duration of HIV-infection (per y: Hazard ratio (HR): 0.91 [0.88–0.94]) and ART (per y: HR: 0.81 [0.79–0.84]) adjusted for age. The proportion of deceased HIV+ with HIV-RNA ≥50 copies/mL and lower CD4-cell counts at their last visit is significantly higher compared with living HIV+ without CVE (HIV-RNA ≥50 copies/mL: 25.6% vs 14.7%). Median CD4-cells: 286.5 cells/µL (IQR: 168.8–482.8) versus 574 cells/µL (IQR: 406–786). 96.1% of the living HIV+ with CVE had HIV-RNA<50 copies

    The interplanetary space probe Cassini/Huygens reached Saturn in July 2004 after seven years of cruise phase. Today, the German-lead Cosmic Dust Analyser (CDA) is operated continuously for 10 years in orbit around Saturn. During the cruise phase CDA measured the interstellar dust flux at one AU distance from the Sun, the charge and composition of interplanetary dust grains and the composition of the Jovian nanodust streams. The first discovery of CDA related to Saturn was the measurement of nanometer sized dust particles ejected by its magnetosphere to interplanetary space with speeds higher than 100 km/s. Their origin and composition was analysed and an their dynamical studies showed a strong link to the conditions of the solar wind plasma flow. A recent surprising result was, that stream particles stem from the interior of Enceladus. Since 2004 CDA measured millions of dust impacts characterizing the dust environment of Saturn. The instrument showed strong evidence for ice geysers located at the south pole of Saturn's moon Enceladus in 2005. Later, a detailed compositional analysis of the salt-rich water ice grains in Saturn's E ring system lead to the discovery of liquid water below the icy crust connected to an ocean at depth feeding the icy jets. CDA was even capable to derive a spatially resolved compositional profile of the plume during close Enceladus flybys. A determination of the dust-magnetosphere interaction and the discovery of the extended E ring allowed the definition of a dynamical dust model of Saturn's E ring describing the observed properties. The measured dust density profiles in the dense E ring revealed geometric asymmetries. Cassini performed shadow crossings in the ring plane and dust grain charges were measured in shadow regions delivering important data for dust-plasma interaction studies. In the last years, dedicated measurement campaigns were executed by CDA to monitor the flux of interplanetary and interstellar dust particles reaching

    Background Peripheral arterial disease (PAD) is associated with major cardiovascular morbidity and mortality. Abnormalities in nitric oxide metabolism due to excess of the NO synthase inhibitor asymmetric dimethylarginine (ADMA) may be pathogenic in PAD. We explored the association between ADMA levels and markers of atherosclerosis, function, and prognosis. Methods and Results 133 patients with symptomatic PAD were enrolled. Ankle brachial index (ABI), walking time, vascular function measures (arterial compliance and flow-mediated vasodilatation) and plasma ADMA level were assessed for each patient at baseline. ADMA correlated inversely with ABI (r = −0.238, p=0.003) and walking time (r = −0.255, p = 0.001), independent of other vascular risk factors. We followed up 125 (94%) of our 133 initial subjects with baseline measurements (mean 35 months). Subjects with ADMA levels in the highest quartile (>0.84 μmol/L) showed significantly greater occurrence of MACE compared to those with ADMA levels in the lower 3 quartiles (p = 0.001). Cox proportional-hazards regression analysis revealed that ADMA was a significant predictor of MACE, independent of other risk factors including age, gender, blood pressure, smoking history, diabetes and ABI (Hazard ratio = 5.1, p<0.001). Measures of vascular function, such as compliance, FMVD and blood pressure, as well as markers of PAD severity, including ABI and walking time, were not predictive. Conclusion Circulating levels of ADMA correlate independently with measures of disease severity and major adverse cardiovascular events. Agents that target this pathway may be useful for this patient population. PMID:20484311

    The objective was to examine real-world treatment patterns of lipid-lowering therapies and their possible associated intolerance and/or ineffectiveness in patients with high cardiovascular disease (CVD) risk initiating statins and/or ezetimibe. Patients aged ≥18 years who initiated statins and/or ezetimibe from January 01, 2007, to June 30, 2011, were retrospectively identified from the IMS LifeLink PharMetrics Plus commercial claims database. Patients were further classified into 2 cohorts: (1) history of cardiovascular event (CVE) and (2) history of coronary heart disease risk equivalent (CHD RE). Patients had continuous health plan enrollment ≥1 year pre- and post-index date (statin and/or ezetimibe initiation date). Primary outcomes were index statin intensity, treatment modifications, possible associated statin/nonstatin intolerance and/or ineffectiveness issues (based on treatment modification), and time-to-treatment modifications. Analyses for each cohort were stratified by age group (<65 and ≥65 years). A total of 41,934 (history of CVE) and 170,344 patients (history of CHD RE) were included. On the index date, 8.8% to 25.1% of patients were initiated on high-intensity statin. Among patients aged <65, 79.2% and 48.8% of those with history of CVE and 78.6% and 47.3% of those with a history of CHD RE had ≥1 and 2 treatment modifications, respectively. Among all patients, 24.6% to 25.6% had possible statin intolerance and/or ineffectiveness issues after accounting for second treatment modification (if any). In conclusion, in patients with high CVD risk, index statin treatment modifications that imply possible statin intolerance and/or ineffectiveness were frequent; low use of high-intensity statins indicates unmet need in the management of hyperlipidemia and possible remaining unaccounted CVD residual risk.

    Objectives To determine whether dietary pattern assessed by a simple self-administered food frequency questionnaire is associated with major adverse cardiovascular events (MACE) in high-risk patients with stable coronary artery disease. Background A Mediterranean dietary pattern has been associated with lower cardiovascular (CV) mortality. It is less certain whether foods common in western diets are associated with CV risk. Methods At baseline, 15 482 (97.8%) patients (mean age 67 ± 9 years) with stable coronary heart disease from 39 countries who participated in the Stabilisation of atherosclerotic plaque by initiation of darapladib therapy (STABILITY) trial completed a life style questionnaire which included questions on common foods. A Mediterranean diet score (MDS) was calculated for increasing consumption of whole grains, fruits, vegetables, legumes, fish, and alcohol, and for less meat, and a ‘Western diet score’ (WDS) for increasing consumption of refined grains, sweets and deserts, sugared drinks, and deep fried foods. A multi-variable Cox proportional hazards models assessed associations between MDS or WDS and MACE, defined as CV death, non-fatal myocardial infarction, or non-fatal stroke. Results After a median follow-up of 3.7 years MACE occurred in 7.3% of 2885 subjects with an MDS ≥15, 10.5% of 4018 subjects with an MDS of 13–14, and 10.8% of 8579 subjects with an MDS ≤12. A one unit increase in MDS >12 was associated with lower MACE after adjusting for all covariates (+1 category HR 0.95, 95% CI 0.91, 0.98, P = 0.002). There was no association between WDS (adjusted model +1 category HR 0.99, 95% CI 0.97, 1.01) and MACE. Conclusion Greater consumption of healthy foods may be more important for secondary prevention of coronary artery disease than avoidance of less healthy foods typical of Western diets. PMID:27109584

    Rheumatoid arthritis (RA) is a complex polygenic inflammatory disease associated with accelerated atherosclerosis, which is the main cause of increased cardiovascular (CV) morbidity and mortality in RA patients. CARD8 is a constituent of inflammasome, which regulates interleukin 1-beta production, and has been associated with a worse disease course in early RA. One thousand six hundred twenty-one patients fulfilling the 1987 ACR classification criteria for RA and 1300 matched controls, were genotyped for the CARD8 rs2043211 (30T>A, p.C10X) single-nucleotide polymorphism (SNP) using predesigned TaqMan SNP genotyping assay. The genotyping success rate in our study was greater than 94%. We assessed CARD8 rs2043211 gene polymorphism results in 1530 Spanish RA patients in whom information on CV disease and CV risk factors was available at the time of the study. Also, a subgroup of patients with no history of CV events (n=276) was assessed for the potential influence of the rs2043211 variant in the development of subclinical atherosclerosis, by measurement of carotid intima-media thickness (IMT) and presence of carotid plaques. No statistically significant differences in allele or genotype frequencies for the rs2043211 CARD8 gene variant between patients with RA and controls were seen. Similarly, CARD8 rs2043211 (30T>A, p.C10X) SNP did not influence the development of CV events or the risk of CV events throughout the time. Likewise, no significant association between this gene variant and carotid IMT or the presence of plaques was found. In summary, our results do not support a role of the CARD8 rs2043211 gene variant in susceptibility to RA or in the development of CV disease in patients with RA. PMID:23088220

    Background Vascular calcification (VC) and carotid intima media thickness (CIMT) are strongly associated with cardiovascular (CV) disease. We hypothesized that significant VC on plain radiographs is associated with CIMT and CV events in dialysis patients. In addition, we evaluated risk factors for VC progression on plain radiographs in dialysis patients. Methods In this 2-year observational, prospective study, 67 dialysis patients were included. We checked plain radiographs at baseline and after 2 years. Laboratory tests and malnutrition score were obtained at baseline, after 12 months, and after 24 months. Results The mean age of patients was 56.3 ± 10.3 years and duration of dialysis was 41.3 ± 34.5 months. The prevalence of significant VC was 61.2% and the prevalence of carotid artery atheromatous plaques was 55.6%. Mean CIMT, malnutrition scores, CRP level and prevalence of carotid atheromatous plaques were significantly higher in patients with significant VC. Serum albumin and total iron binding capacity were significantly lower in patients with significant VC compared to patients without significant VC. During a mean observational period of 22 months, patients without significant VC showed lower CV events by the Kaplan-Meyer method (p = 0.010). Progression of VC was found in 35.7% among 56 patients followed up. Hemoglobin after 24 months was an independent factor for progression of VC (Exp(B) = 0.344, 95% Confidence Interval = 0.13 – 0.96, p = 0.034). Conclusions Significant VC on plain radiograph was associated with CIMT, malnutrition, inflammation, and CV events in dialysis patients. Conditions which increase hemoglobin level may retard progression of VC in dialysis patients. PMID:23360132

    Previous studies that suggest the association of hypertension with cardiovascular disease (CVD) events is stronger in the lean/normal weight than in the obese have either included smokers, diabetics, or cancer patients, or did not account for central obesity. This study examines the interaction of adiposity with hypertension on CVD events using BMI-based definitions of overweight and obesity as well as waist circumference (WC) to assess adiposity. In the Multi-Ethnic Study of Atherosclerosis, we classified 3657 nonsmoking men and women, free of baseline clinical CVD, diabetes and cancer, into 7 BMI-WC combinations defined by ethnicity-specific BMI (normal, overweight, class 1 obese, and class 2/3 obese) and ethnicity- and sex-specific WC categories (optimal or nonoptimal). Adjusted absolute event rates per 1000 person-years and relative risks (RRs) (95% confidence intervals) for CVD events for hypertension (BP ≥ 140/90 or taking medication) vs. no hypertension computed within adiposity categories were: 9.3 vs. 1.9 and 4.96 (2.56-9.60) for normal BMI/optimal WC, 13.2 vs. 4.2 and 3.13 (0.99-9.86) for normal BMI/nonoptimal WC, 9.0 vs. 4.5 and 2.00 (1.19-3.36) for overweight BMI/optimal WC, 8.4 vs. 5.6 and 1.50 (0.88-2.54) for overweight BMI/nonoptimal WC,14.1 vs. 2.1 and 6.75 (0.69-65.57) for class 1 obese/optimal WC, 10.1 vs. 3.7 and 2.69 (1.41-5.16) for class 1 obese/nonoptimal WC, and 9.9 vs. 6.9 and 1.45(0.60-3.52) for class 2/3 obese/WC pooled. This study found a large RR of CVD events associated with hypertension for normal BMI participants and more importantly similarly high absolute risks for both normal and obese BMI with hypertension.

    Objectives Russia faces a high burden of cardiovascular disease. Prevalence of all cardiovascular risk factors, especially hypertension, is high. Elevated blood pressure is generally poorly controlled and medication usage is suboptimal. With a disease-model simulation, we forecast how various treatment programs aimed at increasing blood pressure control would affect cardiovascular outcomes. In addition, we investigated what additional benefit adding lipid control and smoking cessation to blood pressure control would generate in terms of reduced cardiovascular events. Finally, we estimated the direct health care costs saved by treating fewer cardiovascular events. Methods The Archimedes Model, a detailed computer model of human physiology, disease progression, and health care delivery was adapted to the Russian setting. Intervention scenarios of achieving systolic blood pressure control rates (defined as systolic blood pressure <140 mmHg) of 40% and 60% were simulated by modifying adherence rates of an antihypertensive medication combination and compared with current care (23.9% blood pressure control rate). Outcomes of major adverse cardiovascular events; cerebrovascular event (stroke), myocardial infarction, and cardiovascular death over a 10-year time horizon were reported. Direct health care costs of strokes and myocardial infarctions were derived from official Russian statistics and tariff lists. Results To achieve systolic blood pressure control rates of 40% and 60%, adherence rates to the antihypertensive treatment program were 29.4% and 65.9%. Cardiovascular death relative risk reductions were 13.2%, and 29.6%, respectively. For the current estimated 43,855,000-person Russian hypertensive population, each control-rate scenario resulted in an absolute reduction of 1.0 million and 2.4 million cardiovascular deaths, and a reduction of 1.2 million and 2.7 million stroke/myocardial infarction diagnoses, respectively.

    OBJECTIVE To evaluate the accuracy of the UK Prospective Diabetes Study Outcomes Model (UKPDS-OM) in predicting clinical outcomes during the UKPDS posttrial monitoring (PTM) period. RESEARCH DESIGN AND METHODS At trial end in 1997, the 4,031 surviving UKPDS patients, of the 5,102 originally enrolled in the study, returned to their usual care providers, with no attempts made to maintain them in their randomized therapy groups. PTM risk factor data were collected for 5 years and clinical outcome data for 10 years. The UKPDS-OM was used firstly to forecast likely progression of HbA1c, systolic blood pressure, total-to-HDL cholesterol ratio, and smoking status and secondly to estimate the likely first occurrence of seven major diabetes-related complications or death from any cause. Model predictions were compared against observed PTM data for risk factor time paths and survival probabilities for major diabetes complications. RESULTS UKPDS-OM–forecasted risk factor time paths were similar to those observed for HbA1c (up to 3 years) and total-to-HDL cholesterol ratio but underestimated for systolic blood pressure and smoking status. Predicted 10-year event probabilities were similar to those observed for blindness, ischemic heart disease, myocardial infarction, and renal failure but were higher for heart failure and death from any cause and lower for stroke and amputation. CONCLUSIONS The UKPDS-OM has good predictive accuracy for two of four risk factor time paths and for 10-year clinical outcome probabilities with the exception of stroke, amputation, heart failure, and death from any cause. An updated version of the model incorporating PTM data is being developed. PMID:23275370

    Objective To describe the frequency of myocardial infarction (MI) prior to the diagnosis of systemic lupus erythematosus (SLE) and within the first 2 years of follow-up. Methods The systemic lupus international collaborating clinics (SLICC) atherosclerosis inception cohort enters patients within 15 months of SLE diagnosis. MIs were reported and attributed on a specialised vascular event form. MIs were confirmed by one or more of the following: abnormal ECG, typical or atypical symptoms with ECG abnormalities and elevated enzymes (≥2 times upper limit of normal), or abnormal stress test, echocardiogram, nuclear scan or angiogram. Descriptive statistics were used. Results 31 of 1848 patients who entered the cohort had an MI. Of those, 23 patients had an MI prior to SLE diagnosis or within the first 2 years of disease. Of the 23 patients studied, 60.9% were female, 78.3% were Caucasian, 8.7% black, 8.7% Hispanic and 4.3% other. The mean age at SLE diagnosis was 52.5±15.0 years. Of the 23 MIs that occurred, 16 MIs occurred at a mean of 6.1±7.0 years prior to diagnosis and 7 occurred within the first 2 years of follow-up. Risk factors associated with early MI in univariate analysis are male sex, Caucasian, older age at diagnosis, hypertension, hypercholesterolaemia, family history of MI and smoking. In multivariate analysis only age (OR=1.06 95% CI 1.03 to 1.09), hypertension (OR=5.01, 95% CI 1.38 to 18.23), hypercholesterolaemia (OR=4.43, 95% CI 1.51 to 12.99) and smoking (OR=7.50, 95% CI 2.38 to 23.57) remained significant risk factors. Conclusions In some patients with lupus, MI may develop even before the diagnosis of SLE or shortly thereafter, suggesting that there may be a link between autoimmune inflammation and atherosclerosis.

    In this study we present and describe a satellite-derived precipitation climatology over northern South America using a passive microwave technique, the Goddard Profiling Algorithm. A period of data slightly longer than 10 years is examined. The climatologies take the form of the mean estimated (adjusted) rainfall for a 10-year (+) period, with sub-divisions by month and meteorological season. For the six-year period 1992-1997, when two satellites were in operation, diurnal variability (to the extent it is discerned by four unequally spaced observations) is presented. We find an alternating pattern of morning and maxima stretching from the northeast (Atlantic coast) clear across the continent to the Pacific. The effects of topography, coastlines and geography (river valleys) on the rainfall patterns are clear. Interannual variability is examined by computing the deviations of yearly and warm season (DJF) rainfall from their respective long-term means. Interannual variability of the diurnal nature of the rainfall is presented, and the strong El Nino event of 1997-1998 is discussed.

    The Advanced Synthetic Aperture Radar (ASAR) on- board Envisat operated successfully for just over 10 years until the failure of Envisat in April 2012. ASAR was ESA's very first deployment of a C-band phased- array antenna, allowing extended imaging capacity in comparison to its ERS SAR predecessors. As such it operated in various acquisition modes - Image (IM), Alternating Polarisation (AP), Wide Swath (WS), Global Monitoring (GM), and Wave (WV). For IM and AP modes there was a selection of 7 swaths with swath width from 100 km to 56 km: IM was single- polarisation, while AP was dual-pol, offering a choice from HH&VV, HH&HV, or VV&VH. WS and GM modes had a total swath width of 405 km based on the combination of 5 sub-swaths. WV acquired imagettes of 10 km by 10 km every 100 km along the satellite track. This paper is a look back to the 10 years of ASAR operations, covering topics such as the ASAR Instrument (characteristics, acquisition modes, product tree and observation scenario), Instrument Calibration and Performance Verification (including instrument stability, internal calibration, external calibration, absolute radiometric calibration, localisation accuracy, absolute geolocation accuracy, performance verification and product calibration), ASAR specific missions (wave and polarimetric), particular ASAR events such as antenna resets, burst synchronisation, AP swath modifications and the Envisat orbit change in October 2010.

    Abstract To investigate the effects of personality type and psychological stress on the occurrence of major adverse cardiovascular events (MACEs) at 5 years in patients with coronary artery disease (CAD) after percutaneous coronary intervention (PCI). Two hundred twenty patients with stable angina (SA) or non-ST segment elevation acute coronary syndrome (NSTE-ACS) treated with PCI completed type A behavioral questionnaire, type D personality questionnaire, Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale (SAS), Trait Coping Style Questionnaire (TCSQ), and Symptom Checklist 90 (SCL-90) at 3 days after PCI operation. Meanwhile, biomedical markers (cTnI, CK-MB, LDH, LDH1) were assayed. MACEs were monitored over a 5-year follow-up. NSTE-ACS group had higher ratio of type A behavior, type A/D behavior, and higher single factor scores of type A personality and type D personality than control group and SAP group. NSTE-ACS patients had more anxiety, depression, lower level of mental health (P < 0.05; P < 0.01), more negative coping styles and less positive coping styles. The plasma levels of biomedical predictors had positive relation with anxiety, depression, and lower level of mental health. Type D patients were at a cumulative increased risk of adverse outcome compared with non-type D patients (P < 0.05). Patients treated with PCI were more likely to have type A and type D personality and this tendency was associated with myocardial injury. They also had obvious anxiety, depression emotion, and lower level of mental health, which were related to personality and coping style. Type D personality was an independent predictor of adverse events. PMID:27082597

    Abnormal platelet reactivity is associated with recurrent ischemia and bleeding following percutaneous coronary intervention (PCI). Protease-activated receptor-1 (PAR1), encoded by F2R, is a high affinity thrombin receptor on platelets and the target of the antiplatelet drug vorapaxar. The intronic single nucleotide polymorphism F2R IVS-14 A/T affects PAR1 receptor density and function. We hypothesized that carriers of the T allele, who have been shown to have decreased platelet reactivity, would be at lower risk for thrombotic events, but higher risk for bleeding following PCI. Using BioVU, the Vanderbilt DNA repository linked to the electronic medical record, we studied 660 patients who underwent PCI for unstable or stable coronary artery disease. Primary outcome measures were major adverse cardiovascular events (MACE, composite of revascularization, MI, stroke, death) and bleeding (assessed by Bleeding Academic Research Consortium scale) over 24 months. The minor allele (T) frequency was 14.8 %. There were no genotypic differences in the frequency of MACE (33.7, 28.8, and 31.6 % for A/A, A/T, and T/T respectively, P = 0.50) or bleeding (15.7, 14.7, and 18.8 % for A/A, A/T, and T/T respectively, P = 0.90). In a Cox regression model, fully adjusted for age, race, sex, BMI, and smoking status, carrying a T allele was not associated with MACE (HR 1.19, 95 % CI 0.89-1.59, P = 0.23) or bleeding (HR 0.73, 95 % CI 0.37-1.4, P = 0.34). In conclusion, in our population, F2R IVS-14 PAR1 variability does not affect risk of MACE or bleeding following PCI. PMID:26446588

    Background Colchicine may have beneficial effects on cardiovascular (CV) disease, but there are sparse data on its CV effect among patients with gout. We examined the potential association between colchicine and CV risk and all-cause mortality in gout. Methods The analyses used data from an electronic medical record (EMR) database linked with Medicare claims (2006–2011). To be eligible for the study cohort, subjects must have had a diagnosis of gout in the EMR and Medicare claims. New users of colchicine were identified and followed-up from the first colchicine dispensing date. Non-users had no evidence of colchicine prescriptions during the study period and were matched to users on the start of follow-up, age, and gender. Both groups were followed for the primary outcome, a composite of myocardial infarction (MI), stroke or transient ischemic attack (TIA). We calculated hazard ratios (HRs) in Cox regression, adjusting for potential confounders. Results We matched 501 users with an equal number of non-users with a median follow-up of 16.5 months. During follow-up, 28 primary CV events were observed among users and 82 among non-users. Incidence rates per 1,000 person-years were 35.6 for users and 81.8 for non-users. After full adjustment, colchicine use was associated with a 49% lower risk (HR 0.51, 95% CI 0.30 – 0.88) in the primary CV outcome as well as a 73% reduction in all-cause mortality (HR 0.27, 95% CI 017 – 0.43). Conclusion Colchicine use was associated with a reduced risk of a CV event among patients with gout. PMID:26582823

    Objectives To assess whether depression and anxiety increase the risk of mortality and major adverse cardiovascular events (MACE), among patients with and without coronary artery disease (CAD). Design and setting, and patients DECADE (Depression Effects on Coronary Artery Disease Events) is a prospective observational study of 2390 patients referred at the Montreal Heart Institute. Patients were followed for 8.8 years, between 1998 and 2009. Depression and anxiety were assessed using a psychiatric interview (Primary Care Evaluation of Mental Disorders, PRIME-MD). Outcomes data were obtained from Quebec provincial databases. Main outcome measures All-cause mortality and MACE. Results After adjustment for covariates, patients with depression were at increased risks of all-cause mortality (relative risk (RR)=2.84; 95% CI 1.25 to 6.49) compared with patients without depression. Anxiety was not associated with increased mortality risks (RR=0.86; 95% CI 0.31 to 2.36). When patients were stratified according to CAD status, depression increased the risk of mortality among patients with no CAD (RR=4.39; 95% CI 1.12 to 17.21), but not among patients with CAD (RR=2.32; 95% CI 0.78 to 6.88). Neither depression nor anxiety was associated with MACE among patients with or without CAD. Conclusions and relevance Depression, but not anxiety, was an independent risk factor for all-cause mortality in patients without CAD. The present study contributes to a better understanding of the relative and unique role of depression versus anxiety among patients with versus without CAD. PMID:26671946

    It is 10 years since severe acute respiratory syndrome (SARS) emerged, and East and Southeast Asia retain a reputation as a hot spot of emerging infectious diseases. The region is certainly a hot spot of socioeconomic and environmental change, and although some changes (e.g., urbanization and agricultural intensification) may reduce the probability of emerging infectious diseases, the effect of any individual emergence event may be increased by the greater concentration and connectivity of livestock, persons, and products. The region is now better able to detect and respond to emerging infectious diseases than it was a decade ago, but the tools and methods to produce sufficiently refined assessments of the risks of disease emergence are still lacking. Given the continued scale and pace of change in East and Southeast Asia, it is vital that capabilities for predicting, identifying, and controlling biologic threats do not stagnate as the memory of SARS fades.

    Testosterone (T) is the principal male sex hormone. As men age, T levels typically fall. Symptoms of low T include decreased libido, vasomotor instability, and decreased bone mineral density. Other symptoms may include depression, fatigue, erectile dysfunction, and reduced muscle strength/mass. Epidemiology studies show that low levels of T are associated with more atherosclerosis, coronary artery disease, and cardiovascular events. However, treating hypogonadism in the aging male has resulted in discrepant results in regard to its effect on cardiovascular events. Emerging studies suggest that T may have a future role in treating heart failure, angina, and myocardial ischemia. A large, prospective, long-term study of T replacement, with a primary endpoint of a composite of adverse cardiovascular events including myocardial infarction, stroke, and/or cardiovascular death, is needed. The Food and Drug Administration recently put additional restrictions on T replacement therapy labeling and called for additional studies to determine its cardiac safety. PMID:26846952

    There were 161 red tide events collected during the last 10 years from 2001 to 2010 in Fujian coastal waters. Comprehensive analysis was performed using statistical methods and the results indicated the following characteristics of the temporal and spatial distribution of red tide in Fujian coastal waters: (1) Outbreaks of red tide often occurred between April and September, and the peak period was in May and June. Most red tide events lasted for 2 to 4 days, and the affected area was below 50 square kilometers. The first outbreak of red tide tended to occur earlier in recent years, and the lasting time became longer. (2) There were 20 species of organisms causing the red tides in Fujian coastal waters, among which 10 species were Bacillariophyta, 9 species were Dinophyta and 1 species was Protozoa. Prorocentrum donghaiense was the most frequent cause of red tides, followed by Noctiluca scintillans, Skeletonema costatum and Chaetoceros sp.. The species caused red tides obeyed the succession law and there were always new species involved. (2) In terms of spatial distribution, outbreaks of red tides mainly occurred in the coastal waters of Ningde, Fuzhou and Xiamen. The species causing red tides were Prorocentrum donghaiense and Noctiluca in the coastal waters in the north of Pingtan, Fujian Province, Skeletonema costatum and Chaetoceros in the coastal waters in the south of Pingtan, Fujian Province. The comprehensive analysis of the characteristics of red tides during the last 10 years is expected to provide scientific and reasonable basis for the prevention, reduction and forecast of red tides in Fujian coastal waters.

    Sleep disturbance is a common problem in general adult population. Recent evidence suggests the link between the occurrence of cardiovascular events and several sleep disturbances including sleep apnea syndrome, insomnia and periodic limb movements during sleep. Sleep duration may affect the cardiovascular outcome. Shift work also may increase the risk of ischemic heart disease. Normalization of sleep rhythm has a potential to be a therapeutic target of ischemic heart diseases, although further study is required to evaluate the preventive effect on cardiovascular events. Here we describe the current understandings regarding the roles of sleep disorders during the pathogenesis of cardiovascular events. PMID:22844804

    In the Providing Regional Observations to Study Predictors of Events in the Coronary Tree (PROSPECT) study, plaque burden, plaque composition, and minimal luminal area were associated with an increased risk of adverse cardiovascular events arising from untreated atherosclerotic lesions (vulnerable plaques) in patients with acute coronary syndromes (ACS). We sought to evaluate the utility of biomarker profiling and clinical risk factors to predict 3-year all-cause and nonculprit lesion-related major adverse cardiac events (MACEs). Of 697 patients who underwent successful percutaneous coronary intervention (PCI) for ACS, an array of 28 baseline biomarkers was analyzed. Median follow-up was 3.4 years. Beta2-microglobulin displayed the strongest predictive power of all variables assessed for all-cause and nonculprit lesion-related MACE. In a classification and regression tree analysis, patients with beta2-microglobulin >1.92 mg/L had an estimated 28.7% 3-year incidence of all-cause MACE; C-peptide <1.32 ng/ml was associated with a further increase in MACE to 51.2%. In a classification and regression tree analysis for untreated nonculprit lesion-related MACE, beta2-microglobulin >1.92 mg/L identified a cohort with a 3-year rate of 18.5%, and C-peptide <2.22 ng/ml was associated with a further increase to 25.5%. By multivariable analysis, beta2-microglobulin was the strongest predictor of all-cause and nonculprit MACE during follow-up. High-density lipoprotein (HDL), transferrin, and history of angina pectoris were also independent predictors of all-cause MACE, and HDL was an independent predictor of nonculprit MACE. In conclusion, in the PROSPECT study, beta2-microglobulin strongly predicted all-cause and nonculprit lesion-related MACE within 3 years after PCI in ACS. C-peptide and HDL provided further risk stratification to identify angiographically mild nonculprit lesions prone to future MACE.

    Pulse pressure (PP) remains an elusive cardiovascular risk factor with inconsistent findings. We clarified the prognostic value in patients with type 2 diabetes, chronic kidney disease (CKD) and anemia in the Trial to Reduce cardiovascular Events with Aranesp (darbepoetin alfa) Therapy. In 4038 type 2 diabetes patients, darbepoetin alfa treatment did not affect the primary outcome. Risk related to PP at randomization was evaluated in a multivariable model including age, gender, kidney function, cardiovascular disease (CVD) and other conventional risk factors. End points were myocardial infarction (MI), stroke, end stage renal disease (ESRD) and the composite of cardiovascular death, MI or hospitalization for myocardial ischemia, heart failure or stroke (CVD composite). Median (interquartile range) age, gender, eGFR and PP was 68 (60-75) years, 57.3% women, 33 (27-42) ml min(-1) per 1.73 m2 and 60 (50-74) mm Hg. During 29.1 months (median) follow-up, the number of events for composite CVD, MI, stroke and ESRD was 1010, 253, 154 and 668. In unadjusted analyses, higher quartiles of PP were associated with higher rates per 100 years of follow-up of all end points (P⩽0.04), except stroke (P=0.52). Adjusted hazard ratios (95% confidence interval) per one quartile increase in PP were 1.06 (0.99-1.26) for MI, 0.96 (0.83-1.11) for stroke, 1.01 (0.94-1.09) for ESRD and 1.01 (0.96-1.07) for CVD composite. Results were similar in continuous analyses of PP (per 10 mm Hg). In patients with type 2 diabetes, CKD and anemia, PP did not independently predict cardiovascular events or ESRD. This may reflect confounding by aggressive antihypertensive treatment, or PP may be too rough a risk marker in these high-risk patients.

    Purpose. To retrospectively evaluate the 10 year follow-up results in patients who had 'kissing' self-expanding stent aortic bifurcation reconstruction. Methods. Forty-three patients were treated with 'kissing' self-expanding stents for aortoiliac occlusive disease. Early follow-up with clinical and ankle brachial pressure indices (ABPI) was performed at 3, 6, 12, and 24 months and with intra-arterial digital subtraction angiography at 12-24 months; clinical and angiographic follow-up was performed for symptom recurrence up to 10 years after treatment. Retrospective record review was performed to assess mortality, clinical patency, angiographic patency, and secondary assisted patency of both stents and downstream peripheral vessels at 5 and 10 years follow-up. Results. The 2 year primary angiographic and secondary assisted stent patencies were 89% and 93%, respectively. At 10 years follow-up in 40 patients the mortality was 38% (due to myocardial infarction, stroke, chronic renal failure, malignancy, and liver failure). At 5 and 10 years follow-up the primary clinical stent patency was 82% and 68%, and the secondary assisted stent patency 93% and 86%, respectively. At 5 and 10 years, the distal vessel patency was 86% and 72%, and the secondary assisted distal vessel patency treated by surgical or endovascular techniques was 94% and 88%, respectively. At 10 years there was no limb loss. Conclusion. The long-term (10 year) results of aortic bifurcation arterial self-expanding stent placement in patients with arterial occlusive disease show a 10 year primary stent patency rate of 68% but a secondary assisted patency rate of 86%. In addition there is a high overall mortality due to other cardiovascular causes and the rate of distal disease progression and loss of patency is similar to the loss of stent patency rate.

    Abstract There is limited comparative effectiveness evidence to guide approaches to managing diabetes in individuals failing metformin monotherapy. Our aim was to compare the incidence of all-cause mortality and major adverse cardiovascular events (MACEs) among new metformin monotherapy users initiating a dipeptidyl-peptidase-4 inhibitor (DPP4i), glucagon-like peptide-1 receptor agonist (GLP-1RA), sulfonylurea (SU), thiazolidinedione, or insulin. We conducted a cohort study using the UK-based Clinical Practice Research Datalink. Participants included a cohort of 38,233 new users of metformin monotherapy who initiated a 2nd antidiabetic agent between January 1, 2007 and December 31, 2012 with follow-up until death, disenrollment, therapy discontinuation, or study end-date. A subcohort of 21,848 patients with linked hospital episode statistics (HES) and Office of National Statistics (ONS) data were studied to include MACE and cardiovascular-related death. The primary exposure contrasts, defined a priori, were initiation of a DPP4i versus an SU and initiation of a GLP-1RA versus an SU following metformin monotherapy. Cox proportional hazards models were used to assess the relative differences in time to mortality and MACE between exposure contrasts, adjusting for important baseline patient factors and comedications used during follow-up. The main study cohort consisted of 6213 (16%) patients who initiated a DPP4i, 25,916 initiated an SU (68%), 4437 (12%) initiated a TZD, 487 (1%) initiated a GLP-1RA, 804 (2%) initiated insulin, and 376 (1%) initiated a miscellaneous agent as their 2nd antidiabetic agent. Mean age was 62 years, 59% were male, and mean glycated hemoglobin was 8.8% (92.6 mmol/mol). Median follow-up was 2.7 years (interquartile range 1.3–4.2). Mortality rates were 8.2 deaths/1000 person-years for DPP4i and 19.1 deaths/1000 person-years for SU initiators. Adjusted hazards ratio (aHR) for mortality in DPP4i versus SU initiators = 0.58, 95% CI 0

    The OSCAR study was a multicenter, prospective randomized open-label blinded end-point study of 1164 Japanese elderly hypertensive patients comparing the efficacy of angiotensin II receptor blocker (ARB) uptitration to an ARB plus calcium channel blocker (CCB) combination. In this prospective study, we performed prespecified subgroup analysis according to baseline estimated glomerular filtration rate (eGFR) with chronic kidney disease (CKD) defined as an eGFR <60 ml/min per 1.73 m2. Blood pressure was lower in the combined therapy than in the high-dose ARB cohort in both groups with and without CKD. In patients with CKD, significantly more primary events (a composite of cardiovascular events and noncardiovascular death) occurred in the high-dose ARB group than in the combination group (30 vs. 16, respectively, hazard ratio 2.25). Significantly more cerebrovascular and more heart failure events occurred in the high-dose ARB group than in the combination group. In patients without CKD, however, the incidence of primary events was similar between the two treatments. The treatment-by-subgroup interaction was significant. Allocation to the high-dose ARB was a significant independent prognostic factor for primary events in patients with CKD. Thus, the ARB plus CCB combination conferred greater benefit in prevention of cardiovascular events in patients with CKD compared with high-dose ARB alone. Our findings provide new insight into the antihypertensive strategy for elderly hypertensive patients with CKD. PMID:23051740

    The study was to access the association between resting heart rate (RHR) and one-year risk of major adverse cardiovascular events (MACE) in acute coronary syndrome (ACS) patients after percutaneous coronary intervention (PCI). Patients with ACS after PCI (n = 808) were prospectively followed-up for MACE. RHR was obtained from electrocardiogram. MACE was defined as a composite of cardiac death, nonfatal recurrent myocardial infarction, ischemic-driven revascularization, and ischemic stroke. The association between RHR and one-year risk of MACE was assessed using Cox proportional hazards regression model. Compared with patients with RHR >76 bpm, the adjusted hazard ratio (AHR) was 0.51 (95% confidence intervals [CI]: 0.23–1.14; P = 0.100) for patients with RHR < 61 bpm, and 0.44 (95%CI: 0.23–0.85; P = 0.014) for those with RHR 61–76 bpm. For patients with RHR ≥ 61 bpm, an increase of 10 bpm in RHR was associated with an increase by 38.0% in the risk of MACE (AHR: 1.38; 95% CI: 1.04–1.83; P = 0.026). ACS patients after PCI with RHR >76 bpm were at higher risk of MACE during one-year follow-up compared with patients with RHR 61–76 bpm. An elevated RHR ≥ 61 bpm was associated with increased risk of one-year MACE in ACS patients. PMID:26585407

    Objective To examine sex-specific associations, if any, between per-vessel CAD extent and the risk of major adverse cardiovascular events (MACE) over a five-year study duration. Background The presence and extent of coronary artery disease (CAD) diagnosed by coronary computed tomography angiography (CCTA) is associated with increased short-term mortality and MACE. Nevertheless, some uncertainty remains regarding the influence of gender on these findings. Methods 5,632 patients (mean age 60.2 + 11.8 years, 36.5% female) from the CONFIRM (COronary CT Angiography EvaluatioN For Clinical Outcomes: An InteRnational Multicenter) registry were followed over the course of 5 years. Obstructive CAD was defined as ≥50% luminal stenosis in a coronary vessel. Using Cox proportional-hazards models, we calculated the hazard ratio (HR) for incident MACE among women and men, defined as death or myocardial infarction (MI). Results Obstructive CAD was more prevalent in men (42% vs. 26%, p<0.001) whereas women were more likely to have normal coronary arteries (43% vs. 27%, p<0.001). There were a total of 798 incident MACE events. After adjustment, there was a strong association between increased MACE risk and non-obstructive CAD (HR 2.16 for women, 2.56 for men, p<0.001 for both), obstructive one-vessel CAD (HR 3.69 and 2.66, p<0.001), two-vessel CAD (HR 3.92 and 3.55, p<0.001) and three-vessel/left-main CAD (HR 5.94 and 4.44, p<0.001). Further exploratory analyses of atherosclerotic burden did not identify gender-specific patterns predictive of MACE. Conclusion In a large prospective CCTA cohort followed long-term, we did not observe an interaction of gender for the association between MACE risk and increased per-vessel extent of obstructive CAD. These findings highlight the persistent prognostic significance of anatomic CAD subsets as detected by CCTA for the risk of MACE in both women and men. PMID:27056154

    Background and Aims The increase in overweight and obese children may be linked to increased rates of dyslipidaemia. The aim was to assess the prevalence of dyslipidaemia and associated risk factors among the Northern Mexican child population. Methods and Results Four hundred and fifty-one subjects aged between 2 and 10 (47.5% girls) took part in the Nuevo León State Survey of Nutrition and Health 2011–2012. According to the 2011 Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents, serum lipid levels (mg/dL) were categorized into three subgroups (acceptable, borderline-high/low or high/low) as follows: TChol: acceptable <170, borderline-high 170–199, high ≥200; LDL-chol: acceptable <110, borderline-high 110–129, high ≥130; non-HDL-chol: acceptable <120, borderline-high 120–144, high ≥145; HDL-chol: acceptable >45, borderline-low 40–45, low <40; and TG: acceptable <75, borderline-high 75–99, high ≥100 in ≤9 year-old children, and acceptable <90, borderline-high 90–129, and high ≥130 in 10 year-old children. The overall prevalence of borderline-high + high TG, non-HDL-chol, TChol, and LDL-chol was 63.0%, 44.1%, 43.5%, and 29.9%, respectively. The overall prevalence of borderline-low + low HDL-chol was 46.3%. The overall frequency of dyslipidaemia was 54.3%. Thirteen children (2.9%) had all five symptoms of dyslipidaemia. The most common dyslipidaemia was high TG in combination (26.2%) and in isolation (10.6%). Conclusions Half of the children had at least one abnormal lipid concentration. A high TG level was the most frequent dyslipidaemia. Obesity was associated with the occurrence of at least one abnormal lipid level. These findings emphasize the need to pay further attention to the prevention of cardiovascular disease and obesity from an early age. PMID:25793380

    BACKGROUND Preventing obesity is a worldwide public health priority. In vulnerable children living in obesogenic environments, with easy access to high-caloric food, alterations in inhibitory control functions might favor excessive food intake and affect energy regulation. We hypothesized that overweight/obese children would present lower inhibitory control in comparison to normal weight children. METHODS We measured inhibitory control functions in 93 otherwise healthy overweight/obese and 92 normal weight 10-year-old children using the Stroop test and the Go/No-Go task. Event-related potentials were recorded during the Go/No-Go task. RESULTS Overweight/obese children showed slower reaction times (1248.6 ms (95% confidence interval (CI): 1182.9–1314.3) vs 1149.0 ms (95% CI: 1083.0–1215.1)) on the Stroop test, higher reaction time variability (0.25 (95% CI: 0.22–0.27) vs 0.21 (95% CI: 0.19–0.24)) on the Go/No-Go task and decreased P300 amplitude (4.1 µV (95% CI: 3.0–5.2) vs 6.4 µV (95% CI: 5.2–7.6)) on event-related potentials compared with normal weight children. CONCLUSIONS Our results indicate altered inhibitory control functions in otherwise healthy overweight/obese children, which might contribute to their excessive food consumption. PMID:25869603

    Nonalcoholic fatty liver disease (NAFLD) is consistently associated with features of the metabolic syndrome, a condition carrying a high risk of cardiovascular events. We measured the vasodilatory response of the brachial artery in response to ischemia (a test of endothelial function) (FMV) as well as cardiovascular risk profile in 52 NAFLD cases and 28 age- and sex-matched controls. The 10-year risk of coronary events was calculated according to the Framingham equation and the scores derived from the PROCAM study and NCEP-ATPIII proposals. FMV was 6.33% +/- 5.93% in NAFLD versus 12.22% +/- 5.05% in controls (P < .0001), and higher in pure fatty liver (9.93%) compared with nonalcoholic steatohepatitis (4.94%) (P = .010). No differences were observed in flow-independent vasodilation (response to sublingual nitroglycerin). Percent FMV was negatively associated with insulin resistance (homeostasis model assessment) in the whole population (r = -0.243; P = .030). In logistic regression analysis, NAFLD was associated with a percent FMV in the lower tertile (OR, 6.7; 95% CI, 1.26-36.1), after adjustment for age, sex, body mass index, and insulin resistance. Among NAFLD patients, low FMV was associated with nonalcoholic steatohepatitis (adjusted OR, 6.8; 95% CI, 1.2-40.2). The 10-year probability of cardiovascular events was moderately increased in NAFLD, and particularly in nonalcoholic steatohepatitis. In conclusion, our study provides evidence of endothelial dysfunction and increased risk of cardiovascular events in NAFLD. The risk of advanced liver disease is well recognized in NAFLD patients, but the large majority of cases might experience cardiovascular disease in the long term, indirectly limiting the burden of liver failure.

    Whereas statins and acetylsalicylic acid (ASA) are considered gold standard for secondary prevention following myocardial infarction or atherotrombotic stroke, there are inconsistent data on the use of these drugs for primary prevention in patients with increased cardiovascular risk. Some meta-analyses indicated that the use of statins and ASA for primary prevention of cardiovascular disease can reduce the risk of cardiovascular events such as ischemic stroke or myocardial infarction. However, the effects of primary prevention with statins and ASA on mortality varied in the data included in these meta-analyses. Therefore the guidelines of the German College of General Practitioners and Family Physicians recommend primary prevention with statins and ASA only in those patients who have a 10-year risk of cardiovascular events which exceeds 20 %. Divergently, primary prevention with ASA is not recommended by the European Society of Cardiology. Observational studies suggested that treatment success of primary prevention with statins and ASA depends on various factors such as adherence to medication and prescription behavior of physicians. This review summarizes the current literature on primary prevention of cardiovascular events with ASA and statins.

    The inability to maintain the upright posture due to a failure in the arterial blood pressure regulatory mechanisms on return from space travel or after a period of head down tilt bed rest (HDBR) is the ultimate sign of cardiovascular deconditioning. Yet, the final response of syncope is potentially heralded by a series of precursor events that can be quantified and analyzed in new, more insightful ways to attempt to understand the integrative nature of autonomic control of the cardiovascular system.

    Abstract Total hip arthroplasty is a common and important treatment for osteoarthritis patients. Long-term cardiovascular effects elicited by osteoarthritis or the implant itself remain unknown. The purpose of the present study was to determine if there is an increased risk of late cardiovascular mortality and morbidity after total hip arthroplasty surgery. A nationwide matched cohort study with data on 91,527 osteoarthritis patients operated on, obtained from the Swedish Hip Arthroplasty Register. A control cohort (n = 270,688) from the general Swedish population was matched 1:3 to each case by sex, age, and residence. Mean follow-up time was 10 years (range, 7–21). The exposure was presence of a hip replacement for more than 5 years. The primary outcome was cardiovascular mortality after 5 years. Secondary outcomes were total mortality and re-admissions due to cardiovascular events. During the first 5 to 9 years, the arthroplasty cohort had a lower cardiovascular mortality risk compared with the control cohort. However, the risk in the arthroplasty cohort increased over time and was higher than in controls after 8.8 years (95% confidence interval [CI] 7.0–10.5). Between 9 and 13 years postoperatively, the hazard ratio was 1.11 (95% CI 1.05–1.17). Arthroplasty patients were also more frequently admitted to hospital for cardiovascular reasons compared with controls, with a rate ratio of 1.08 (95% CI 1.06–1.11). Patients with surgically treated osteoarthritis of the hip have an increased risk of cardiovascular morbidity and mortality many years after the operation when compared with controls. PMID:26871792

    Background Pulse pressure (PP) is a risk factor for cardiovascular disease. It has been reported that ambulatory blood pressure (BP) and nighttime BP parameters are heritable traits. However, the genetic association of pulse pressure and its clinical impact remain undetermined. Method and Results We conducted a genome-wide association study of PP using ambulatory BP monitoring in young-onset hypertensive patients and found a significant association between nighttime PP and SNP rs897876 (p = 0.009) at chromosome 2p14, which contains the predicted gene FLJ16124. Young-onset hypertension patients carrying TT genotypes at rs897876 had higher nighttime PP than those with CT and CC genotypes (TT, 41.6±7.3 mm Hg; CT, 39.1±6.0 mm Hg; CC, 38.9±6.3 mm Hg; p<0.05,). The T risk allele resulted in a cumulative increase in nighttime PP (β = 1.036 mm Hg, se. = 0.298, p<0.001 per T allele). An independent community-based cohort containing 3325 Taiwanese individuals (mean age, 50.2 years) was studied to investigate the genetic impact of rs897876 polymorphisms in determining future cardiovascular events. After an average 7.79±0.28 years of follow-up, the TT genotype of rs897876 was independently associated with an increased risk (in a recessive model) of coronary artery disease (HR, 2.20; 95% CI, 1.20–4.03; p = 0.01) and total cardiovascular events (HR, 1.99; 95% CI, 1.29–3.06; p = 0.002), suggesting that the TT genotype of rs897876C, which is associated with nighttime pulse pressure in young-onset hypertension patients, could be a genetic prognostic factor of cardiovascular events in the general cohort. Conclusion The TT genotype of rs897876C at 2p14 identified in young-onset hypertensive had higher nighttime PP and could be a genetic prognostic factor of cardiovascular events in the general cohort in Taiwan.

    Public health facilities in Iran are exposed to a wide range of natural hazards. This article presents the first survey of the impacts of such natural hazards on primary health care (PHC) centers in Iran from 2001 to 2011. A retrospective survey was conducted in 25 out of 30 provinces of Iran. Archival reports at provincial public health departments were cross-referenced with key informant interviews. During a 10-year period, 119 natural hazard events were recorded that led to physical damage and/or functional failure in 1,401 health centers, 127 deaths and injury or illness in 644 health staff. Earthquakes accounted for the most physical damage and all health-worker deaths. However, there was an increasing trend of impacts due to hydro-meteorological hazards. Iran’s health system needs to establish a registry to track the impact of natural hazards on health facilities, conduct regular hazard and vulnerability assessments and increase mitigation and preparedness measures.

  12. HRT and cardiovascular disease.

    PubMed

    Stevenson, John C

    2009-02-01

    Hormone replacement therapy (HRT) has profound effects on the cardiovascular system, with plausible biological mechanisms explaining both the benefits and harm. Benefits may result from oestrogen action on metabolic risk factors, such as lipids, glucose and insulin metabolism, as well as direct arterial effects, reducing atherogenesis. Harm may arise from inappropriately high starting doses causing transient increases in coagulation activation and adverse vascular remodelling. Observational studies of HRT suggest that there is a beneficial effect on the incidence of coronary heart disease (CHD). Any benefit of HRT seen in randomized clinical trials appears to be confined to those women within several years of their menopause, and it is clear from the randomized trials that age at initiation is a crucially important consideration. Women initiating HRT within 10 years of menopause onset may achieve cardiovascular benefit, particularly in terms of primary CHD prevention, whilst avoiding risks of stroke and venous thrombo-embolism.

    Aim To investigate whether diagnostic data from implanted cardiac resynchronization therapy defibrillators (CRT-Ds) retrieved automatically at 24 h intervals via a Home Monitoring function can enable dynamic prediction of cardiovascular hospitalization and death. Methods and results Three hundred and seventy-seven heart failure patients received CRT-Ds with Home Monitoring option. Data on all deaths and hospitalizations due to cardiovascular reasons and Home Monitoring data were collected prospectively during 1-year follow-up to develop a predictive algorithm with a predefined specificity of 99.5%. Seven parameters were included in the algorithm: mean heart rate over 24 h, heart rate at rest, patient activity, frequency of ventricular extrasystoles, atrial–atrial intervals (heart rate variability), right ventricular pacing impedance, and painless shock impedance. The algorithm was developed using a 25-day monitoring window ending 3 days before hospitalization or death. While the retrospective sensitivities of the individual parameters ranged from 23.6 to 50.0%, the combination of all parameters was 65.4% sensitive in detecting cardiovascular hospitalizations and deaths with 99.5% specificity (corresponding to 1.83 false-positive detections per patient-year of follow-up). The estimated relative risk of an event was 7.15-fold higher after a positive predictor finding than after a negative predictor finding. Conclusion We developed an automated algorithm for dynamic prediction of cardiovascular events in patients treated with CRT-D devices capable of daily transmission of their diagnostic data via Home Monitoring. This tool may increase patients’ quality of life and reduce morbidity, mortality, and health economic burden, it now warrants prospective studies. ClinicalTrials.gov  NCT00376116. PMID:21852311

    Background Asymmetric dimethylarginine (ADMA) is associated with increased risk of atherosclerotic cardiovascular disease and mortality through inhibition of nitrogen oxide (NO) synthesis. As positive correlations between serum concentrations of NO and body mass index (BMI) have been observed, we aimed to explore whether the potential associations between plasma ADMA levels and the risk of acute myocardial infarction (AMI) and mortality were modified by BMI. Methods Multivariable Cox proportional hazard models were used to estimate the hazard ratios (HR) for AMI, cardiovascular death and all-cause mortality according to baseline plasma ADMA levels in 4122 patients with suspected stable angina pectoris. Analyses were subsequently repeated in patients with BMI below (low BMI) or above (high BMI) median. Results A total of 2982 patients (72%) were men. Median (range) age, plasma ADMA level and BMI were 62 (21–88) years, 0.54 (0.10–1.25) μmol/L and 26.3 (18.5–54.3) kg/m2, respectively. During a mean (standard deviation) follow-up time of 4.7 (1.4) years, 337 (8%) patients suffered from an AMI, 300 (7%) died, whereof 165 (55%) due to cardiovascular disease. Each 0.1 μmol/L increment in plasma ADMA level was associated with an increased risk of AMI (HR (95% CI) 1.21 (1.08, 1.35) and cardiovascular death 1.30 (1.13, 1.49) in participants with low BMI only. Interactions were significant for AMI (p = 0.04) and CV death (p = 0.03). BMI did not modify the association between plasma ADMA levels and all-cause mortality. Conclusion Plasma ADMA levels were associated with risk of AMI and cardiovascular death among patients with low BMI only. PMID:27003294

    Shared environmental factors may confer to spouses a similar risk for cardiovascular disease. We aimed at investigating in pairs the concordance in risk factors for cardiovascular disease and in global risk of cardiovascular events. In the framework of the IMMIDIET Project, married couples, recruited randomly from general practice, were studied. One thousand six hundred and four apparently healthy subjects aged 25-74 years from three different European populations were enrolled. Individual cardiovascular risks were estimated using SCORE risk equations. Age was strongly correlated within couples (r = 0.86, P < 0.0001). In multivariate model, within-pair correlation was high for social status (r = 0.49; percentage of explained variation = 24%) and percent of calories from lipids (r = 0.34; 12%). Concerning conventional metabolic risk factors, percentage of explained variation varied from 0.5% (triglycerides) to 11% (glucose). Among new risk factors, activated factor VII showed the strongest correlation (r = 0.28) and C-reactive protein the lowest (r = 0.13). Either total, coronary or non-coronary risk estimates at 10 years were strongly correlated within pairs: the risk of a member explained about two thirds of the cardiovascular risk of the partner. Spouse pairs share common lifestyle habits, common and new metabolic risk factors and the predicted global risk of cardiovascular events. If the individual risk of a person is influenced by the risk of his/her partner, decreasing the risk in a member of the pair should also decrease the risk in the partner. These concepts may have important public health consequences in targeting screening or disease prevention measures towards partners of people with cardiovascular risk.

    Metabolic syndrome is a cluster of risk factors for cardiovascular disease that affects an estimated 50 million Americans. The present article reviews the metabolic syndrome with respect to its definition, epidemiology, pathophysiology and management. A primary focus in research has been to elucidate the processes determined to cause insulin resistance, the fundamental mechanism underlying the metabolic syndrome. Namely, the incidence, component characteristics and complications of the metabolic syndrome in the island of Puerto Rico are described alongside the fact that the metabolic syndrome may be milder in Puerto Rico than in the mainland United States because it is characterized by less aggressive coronary disease and a relatively normal lipid profile. This suggests that the cardiovascular complications are more influenced by genetics and culture than diabetes mellitus and hypertension.

    In an open study, self-ratings of bodily symptoms, mood (before and after stress), and cognitive performance were investigated in 25 women (aged 54-66 years) who for approximately 10 years had been taking an oral preparation of hormone replacement therapy (HRT), tibolone (Livial; 2.5 mg/ day). Tibolone has a unique profile, with estrogenic, progestogenic, and androgenic actions. The control group of 25 women had never taken HRT. Each woman in this group was pair-matched to one in the tibolone group on age, years since menopause, IQ, years of secondary education, and occupation. The groups were matched on their anxiety and depression scores on the Hospital Anxiety and Depression rating scale. Exclusion criteria were scores on this scale in the clinical range and any current illness or recent use of psychoactive medication. The women who were taking tibolone felt significantly less clumsy and had less severe palpitations than the control group. After exposure to a mildly stressful test, the control group felt more anxious, but this change was not seen in the group receiving tibolone. The group taking tibolone had significantly better semantic memory (memory for facts), as assessed in a category generation task, but they did not differ in tests of episodic memory (memory for events). An unexpected finding was that the tibolone group performed significantly worse on a sustained attention task and a planning task, tasks that are associated with frontal lobe function. Our results suggest that the effects of HRT on cognition may be influenced by the type of HRT, the duration of treatment, the nature of the tests, and the brain region controlling the cognitive function.

    PurposeCarotid endarterectomy and stenting are used to treat carotid stenosis, with the volume of carotid artery procedures increasing over the past decade. We investigated the 10-year trend of periprocedural complications with an increasing procedure volume of carotid stenting at a single tertiary hospital.MethodsWe collected 416 consecutive cases (384 patients) of carotid artery stenting performed for either symptomatic (231 cases, 55.5 %) or asymptomatic (185 cases, 44.5 %) internal carotid artery stenosis at a single center. Periprocedural complication was defined as any stroke, myocardial infarction, or death. Procedure-related outcome included any dissection, hemodynamic event, or periprocedural complication.ResultsThe mean age was 68.8 years (82.8 % males; range of 20–89 years); 23.9 % were older than 75 years. Before the procedure, 99.3 and 56.0 % of patients received antiplatelet and lipid-lowering medication, respectively. The overall periprocedural complication rate was 3.6 % (1.6 and 5.2 % in the asymptomatic and symptomatic group, respectively). The composite outcome of any stroke or death was 3.4 %. Periprocedural complication and procedure-related outcome showed a decremental trend with increasing procedure volume, and this trend remained after adjusting for confounders.ConclusionsOur study suggests that carotid stenting at an experienced center might reduce the periprocedural complications. Our periprocedural complication rate of carotid artery stenting may be comparable to, or somewhat lower than, that reported in other clinical trials.

  4. Soil erosion in the Swiss midlands: Results of a 10-year field survey

    2011-03-01

    Long-term field monitoring of soil erosion by water was conducted on arable land in the Swiss midlands. All visible erosion features in 203 fields were continuously mapped and quantified over 10 years. The eroded soil volume associated with linear erosion features was calculated by measuring the length and cross-sectional area in rills at representative positions and the extent of interrill erosion was estimated. Averaged across the 10 study years, just under one-third (32.2%) of the fields exhibited erosion. With 0.75 t ha -1 yr -1 (mean) and 0.56 t ha -1 yr -1 (median), the average annual soil loss of the region was relatively small. The year-to-year variation in soil loss of the region was great and ranged from 0.16 to 1.83 t ha -1 yr -1. The maximum annual soil erosion in a single field was 96 t yr -1 or 58 t ha -1 yr -1, thus demonstrating that only a few erosion events on a few fields may decisively contribute to the total extent of soil erosion in a region. Linear and interrill erosion accounted for 75% and 25% of total soil loss, respectively. Wheel tracks, furrows, headlands, and slope depressions were important on-site accelerators of erosion. Run-on from adjacent upslope areas was an important trigger of erosion. Of the soil moved by erosion, 52% was deposited within the field of origin. A high proportion (72%) of the linear erosion features caused off-site damage. Part of the total eroded soil (20%) was transported into water, thereby contributing to their contamination. The long-term field assessment of soil erosion helps to fill existing knowledge gaps concerning temporal and spatial variability of soil erosion on arable land, the extent and severity of soil erosion and its sources and causes, as well as subsequent off-site damage.

    Spaceflight causes adaptive changes in cardiovascular function that may deleteriously affect crew health and safety. Over the last three decades, symptoms of cardiovascular changes have ranged from postflight orthostatic tachycardia and decreased exercise capacity to serious cardiac rhythm disturbances during extravehicular activities (EVA). The most documented symptom of cardiovascular dysfunction, postflight orthostatic intolerance, has affected a significant percentage of U.S. Space Shuttle astronauts. Problems of cardiovascular dysfunction associated with spaceflight are a concern to NASA. This has been particularly true during Shuttle flights where the primary concern is the crew's physical health, including the pilot's ability to land the Orbiter, and the crew's ability to quickly egress and move to safety should a dangerous condition arise. The study of astronauts during Shuttle activities is inherently more difficult than most human research. Consequently, sample sizes have been small and results have lacked consistency. Before the Extended Duration Orbiter Medical Project (EDOMP), there was a lack of normative data on changes in cardiovascular parameters during and after spaceflight. The EDOMP for the first time allowed studies on a large enough number of subjects to overcome some of these problems. There were three primary goals of the Cardiovascular EDOMP studies. The first was to establish, through descriptive studies, a normative data base of cardiovascular changes attributable to spaceflight. The second goal was to determine mechanisms of cardiovascular changes resulting from spaceflight (particularly orthostatic hypotension and cardiac rhythm disturbances). The third was to evaluate possible countermeasures. The Cardiovascular EDOMP studies involved parallel descriptive, mechanistic, and countermeasure evaluations.

    The Japan Hypertension Evaluation with Angiotensin II Antagonist Losartan Therapy (J-HEALTH) study was performed to investigate the relationship between blood pressure (BP) and development of stroke or myocardial infarction (MI) in Japanese hypertensive patients. A total of 26,512 hypertensive patients (mean age: 62.2 years, 43.9% men) were analyzed. All patients received open-labelled losartan for a maximum of 5 years. Endpoints were stroke, MI including sudden cardiac death, and all cardiovascular (CV) events (stroke and MI). The mean observation period was 3.0 years. The mean baseline systolic/diastolic BP was 165.8/94.8 mmHg and decreased to 141.6/82.0 mmHg during treatment. The incidences of stroke, MI, and total CV events were 3.90, 1.02, and 4.92 per 1,000 patient-years, respectively. Aging, diabetes, a history of CV disease, and smoking were independent risk factors for CV events. The risk of all CV events was positively related to BP level during treatment, and increased significantly when the BP exceeded 140/90 mmHg. Age was a strong contributor to CV events, but about a half of the very elderly patients (>or=85 years, n=692) had a BP below 140/90 mmHg during treatment and significantly fewer events occurred in these patients than in those with a BP of 140/90 mmHg or higher. These results suggest that BP should be below 140/90 mmHg in Japanese patients with hypertension for reducing the risk of CV events. BP was controlled below 140/90 mmHg in a half of the very elderly hypertensive patients in this study, and these patients also had a lower incidence of CV events.

    Background. Retrospective, observational studies link high phosphate with mortality in dialysis patients. This generates research hypotheses but does not establish “cause-and-effect.” A large randomised controlled trial (RCT) of about 3000 patients randomised 50 : 50 to lower or higher phosphate ranges is required to answer the key question: does reducing phosphate levels improve clinical outcomes? Whether such a trial is technically possible is unknown; therefore, a study is necessary to inform the design and conduct of a future, definitive trial. Methodology. Dual centre prospective parallel group study: 100 dialysis patients randomized to lower (phosphate target 0.8 to 1.4 mmol/L) or higher range group (1.8 to 2.4 mmol/L). Non-calcium-containing phosphate binders and questionnaires will be used to achieve target phosphate. Primary endpoint: percentage successfully titrated to required range and percentage maintained in these groups over the maintenance period. Secondary endpoints: consent rate, drop-out rates, and cardiovascular events. Discussion. This study will inform design of a large definitive trial of the effect of phosphate on mortality and cardiovascular events in dialysis patients. If phosphate lowering improves outcomes, we would be reassured of the validity of this clinical practice. If, on the other hand, there is no improvement, a reassessment of resource allocation to therapies proven to improve outcomes will result. Trial Registration Number. This trial is registered with ISRCTN registration number ISRCTN24741445. PMID:26366297

    Based on global cardiovascular (CV) risk assessment for example using the Framingham risk score, it is recommended that those with high risk should be treated and those with low risk should not be treated. The recommendation for those of medium risk is less clear and uncertain. We aimed to determine whether factoring in chronic kidney disease (CKD) will improve CV risk prediction in those with medium risk. This is a 10-year retrospective cohort study of 905 subjects in a primary care clinic setting. Baseline CV risk profile and serum creatinine in 1998 were captured from patients record. Framingham general cardiovascular disease risk score (FRS) for each patient was computed. All cardiovascular disease (CVD) events from 1998–2007 were captured. Overall, patients with CKD had higher FRS risk score (25.9% vs 20%, p = 0.001) and more CVD events (22.3% vs 11.9%, p = 0.002) over a 10-year period compared to patients without CKD. In patients with medium CV risk, there was no significant difference in the FRS score among those with and without CKD (14.4% vs 14.6%, p = 0.84) However, in this same medium risk group, patients with CKD had more CV events compared to those without CKD (26.7% vs 6.6%, p = 0.005). This is in contrast to patients in the low and high risk group where there was no difference in CVD events whether these patients had or did not have CKD. There were more CV events in the Framingham medium risk group when they also had CKD compared those in the same risk group without CKD. Hence factoring in CKD for those with medium risk helps to further stratify and identify those who are actually at greater risk, when treatment may be more likely to be indicated. PMID:26496190

    Erectile dysfunction is common in the patient with cardiovascular disease. It is an important component of the quality of life and it also confers an independent risk for future cardiovascular events. The usual 3-year time period between the onset of erectile dysfunction symptoms and a cardiovascular event offers an opportunity for risk mitigation. Thus, sexual function should be incorporated into cardiovascular disease risk assessment for all men. A comprehensive approach to cardiovascular risk reduction (comprising of both lifestyle changes and pharmacological treatment) improves overall vascular health, including sexual function. Proper sexual counselling improves the quality of life and increases adherence to medication. This review explores the critical connection between erectile dysfunction and cardiovascular disease and evaluates how this relationship may influence clinical practice. Algorithms for the management of patient with erectile dysfunction according to the risk for sexual activity and future cardiovascular events are proposed.

    The risk of infection in advanced chronic kidney disease (CKD) and its subsequent impact on adverse outcomes are not well established. Therefore, we determined the association of an infectious episode with the subsequent risk of cardiovascular ischemia, congestive heart failure, end-stage kidney disease or mortality in a Canadian prospective cohort (CanPREDDICT) of patients with advanced CKD (eGFR: 15-45 ml/min/1.73m(2)) followed by nephrologists for up to 5 years. Infectious episodes were classified by anatomic location and identified by positive culture, hospital admission, or use of antibiotics. Competing risk models were used to examine the time-varying risk of infection and the risk of cardiovascular ischemia, congestive heart failure, or end-stage kidney disease accounting for the competing risk of mortality. All outcomes were independently adjudicated. Of 2370 patients (mean age, 68 years; mean baseline eGFR, 28.2 mL/min/1.73m(2)), 575 patients (24.3%) had recorded infections; 378 had 1 infection episode, whereas 197 had 2 or more episodes, the most common being urinary and respiratory. An infectious episode was independently associated with an increased risk of cardiovascular ischemia (hazard ratio 1.80, 95% confidence interval 1.24-2.60), congestive heart failure (hazard ratio, 3.2; confidence interval, 2.25-4.61), end-stage kidney disease (hazard ratio, 1.58; confidence interval, 1.22-2.05) or mortality (hazard ratio, 3.39; confidence interval, 2.65-4.33). Thus, there is a high risk of infection in advanced CKD being associated with subsequent adverse outcomes. PMID:27591084

    Coagulation markers may improve monitoring the risk of stroke and bleeding in patients with atrial fibrillation (AF) during anticoagulant treatment. We examined baseline levels of D-dimer and their association with stroke, cardiovascular death and major bleeding in 6,202 AF patients randomised to dabigatran or warfarin in the RE-LY trial. The effects of treatment on serial levels of D-dimer and coagulation factor (F) VIIa in 2,567 patients were also analysed. Baseline D-dimer levels were related to the rate of stroke/systemic embolism (SEE) with 0.64 % in the lowest quartile (Q1, as reference) (D-dimer < 298 µg/l), 1.38 % Q2 (D-dimer 298-473 µg/l), 1.71 % Q3 (D-dimer 474-822 µg/l) and 2.00 % in Q4 (D-dimer > 822 µg/l) (p=0.0007). Similar associations were shown for cardiovascular death and major bleeding. Addition of baseline D-dimer to established clinical risk factors improved prediction of stroke/SEE, cardiovascular death and major bleeding (C-index increased from 0.66 to 0.68, 0.71 to 0.73 and 0.66 to 0.67, respectively). Dabigatran provided a greater reduction of D-dimer levels than warfarin regardless of baseline anticoagulant treatment. On-treatment levels of FVIIa were markedly reduced by warfarin (median 12.1-13.8 mU/ml) but significantly higher with dabigatran (median 39.4-49.0 mU/ml) at all-time points. Dabigatran is associated with greater reduction in D-dimer without the pronounced reduction of FVIIa seen with warfarin. These different effects on the coagulation system might explain the better efficacy and less intracranial bleeding observed with dabigatran compared with warfarin.

    Among the new cardiovascular event (CVE) risk biomarkers, C-reactive protein detected using high sensitive techniques (hs-CRP) has been one of the most commonly evaluated. In this review, the available evidence on the usefulness of hs-CRP was explored as an independent risk event factor in subjects with no cardiovascular history and as prognosis in case of chronic or acute cardiovascular condition. An overview (revision of revisions) was carried out searching in the main bibliographic databases and in other general Internet search engines. During the first stage, systematic reviews, clinical practice guidelines, health technology assessments and coverage policies were found and, during the second stage primary studies published after the systematic review search dates were added. Seven hundred and seventy four quotes were found, including 36 papers assessing the role of hs-CRP in healthy populations or with cardiovascular history. High quality evidence was found pointing out hs-CRP, both as risk factor in the general population and as prognostic factor in those with CVE, in all the populations assessed. It was most useful in subjects with a history of CVE and intermediate risk of events at 10 years; where adding hs-CRP to the classical models for event risk estimation improves risk staging. There was no consensus on its clinical usefulness as a prognostic marker in subjects with chronic or acute disease. PMID:25700576

    On the basis of a critical literature review, this article deals with the concepts of global cardiovascular risk and cardiometabolic risk, pointing out their links but also their unresolved issues and discussing their usefulness in clinical practice. The global cardiovascular risk is the probability of suffering from a coronary event or stroke in a given period of time and in this sense it is an absolute risk, generally reported as percentage at 10 years. Usually risk functions are used, derived from longitudinal studies of healthy people at baseline. They consider some factors that are coherently linked with events in population analyses: among these there are some metabolic factors (total cholesterol, HDL cholesterol, fasting blood glucose), some biological factors (blood pressure) and some lifestyle factors (tobacco smoking), all modifiable beyond those non-modifiable like age and gender. The chosen factors must be independent at multivariate analysis, simple and standardized to measure, and contribute to significantly increase the risk-function predictivity. To be reliable, these risk functions must be derived from the same population where they will be later administered. For this reason the Italian Progetto CUORE, in the longitudinal study section, built a database of risk factors from longitudinal comparable studies started between the mid '80s and '90s and followed up the participants for cardiovascular mortality and morbidity to estimate the Italian global cardiovascular risk (first coronary or cerebrovascular event) for men and women. Two tools have been produced, the risk charts and a score software (see www.cuore.iss.it). The ongoing epidemics of obesity and diabetes and the fact that diabetes is associated with classical risk factors like hypertension and dyslipidemia induced the American Diabetes Association and the American Heart Association to launch a "call to action" to prevent both cardiovascular disease and diabetes.

    Background New‐onset atrial fibrillation (AF) is reported to increase the risk of death in myocardial infarction (MI) patients. However, previous studies have reported conflicting results and no data exist to explain the underlying cause of higher death rates in these patients. Methods and Results All patients with first acute MI between 1997 and 2009 in Denmark, without prior AF, were identified from Danish nationwide administrative registers. The impact of new‐onset AF on all‐cause mortality, cardiovascular death, fatal/nonfatal stroke, fatal/nonfatal re‐infarction and noncardiovascular death, were analyzed by multiple time‐dependent Cox models and additionally in propensity score matched analysis. In 89 703 patients with an average follow‐up of 5.0±3.5 years event rates were higher in patients developing AF (n=10 708) versus those staying in sinus‐rhythm (n=78 992): all‐cause mortality 173.9 versus 69.4 per 1000 person‐years, cardiovascular death 137.2 versus 50.0 per 1000 person‐years, fatal/nonfatal stroke 19.6/19.9 versus 6.2/5.6 per 1000 person‐years, fatal/nonfatal re‐infarction 29.0/60.7 versus 14.2/37.9 per 1000 person‐years. In time‐dependent multiple Cox analyses, new‐onset AF remained predictive of increased all‐cause mortality (HR: 1.9 [95% CI: 1.8 to 2.0]), cardiovascular death (HR: 2.1 [2.0 to 2.2]), fatal/nonfatal stroke (HR: 2.3 [2.1 to 2.6]/HR: 2.5 [2.2 to 2.7]), fatal/nonfatal re‐infarction (HR: 1.7 [1.6 to 1.8]/HR: 1.8 [1.7 to 1.9]), and non‐ cardiovascular death (HR: 1.4 [1.3 to 1.5]) all P<0.001). Propensity‐score matched analyses yielded nearly identical results (all P<0.001). Conclusions New‐onset AF after first‐time MI is associated with increased mortality, which is largely explained by more cardiovascular deaths. Focus on the prognostic impact of post‐infarct AF is warranted. PMID:24449803

    Although being a relatively old phenomenon, drug-facilitated crime has been well described over the past 20 years as being the administration without the knowledge of the victim of a psychoactive substance in criminal purposes (rape, robbery, theft, money extortion, even murder). Drug-facilitated crime involves also mistreatment of older people or children treated by their parents in order to obtain sedation. Drug-facilitated crimes are often difficult to solve mainly due to analytical issues. Since 10 years, we developed and improved specific methods using LC-MS/MS (benzodiazepines, neuroleptics) and GC-MS/MS (GHB, cannabis) to detect the drugs involved in such crimes. After the intake of a low dosage of a particular drug, those methods allow to detect the analyte of interest up to 3-5 days in blood, 10-15 days in urine, and more than 1 year in hair. In drug-facilitated crime cases, blood and urine are frequently collected too late, more than 12 h after the drug intake and in some cases with a delay greater than 48 h after the event. Thus, the most used molecules are undetectable by the techniques classically used in a laboratory of biology. Moreover, a "good" compound that can be used to commit a drug-facilitated crime usually possesses a short elimination half-life and amnesic properties, so that the victim is less able to accurately recall the circumstances under which the offence occurred. The recent progress in analytical toxicology, particularly for laboratories working in the field of forensic toxicology, permits to elucidate many cases of drug-facilitated crimes. Heaven to the introduction of the sequential analysis of hair and the use of sophisticated analytical techniques such as tandem mass-spectrometry for the toxicologist to bring the scientific proof to the applicant authorities in the description of the criminal act and to confuse the offender. The author presents the results of 583 presumed cases of drug-facilitated crimes analyzed by his

    Adipose tissue tumors in ten years of diagnostic activity (1979-1988). We have reconsidered our material on tumors of adipose tissue, which were observed for 10 years, from 1979 to 1988, at Istituto di Anatomia Patologica dell'Università degli Studi - Arcispedale S. Anna di Ferrara. The whole collection consists of 772 tumors, 742 lipomas and 30 liposarcomas. We have intended to examine the development of our diagnostic experience through time and compare our data with those of literature. Simple lipomas and fibrolipomas are the most common histological types (78.8%), followed by angiolipomas (3.6%) and intramuscular lipomas (2.5%). The other types have a lower percentage. In every cases the morphologic and clinicopathologic features are shown, as well as compared with those of literature, and discordances that may result are interpreted. We are firmly convinced that routine diagnosis is not always compatible with rigid classifications and that it is not easy to use morphologic criteria which vary in quality and quantity. We have consequently aimed at reducing any possible distortion in diagnosis due to subjectivity, by sticking rigorously to consolidated morphology. Although our findings mostly agree with those of literature, some discordances still exist; the most significant of them regard age incidence. Among spindle cell lipomas there are two cases diagnosed in early childhood; the number of angiolipomas as well seems to be very high in this period of life. Particularly important from the clinical point of view has been the decision of diagnosing a thigh tumor as lipoblastoma in an eighteen-year-old boy. Other discordances seem to us less significant, as, for example, the absence of intramuscular lipomas in the thigh, which is to be considered, in our opinion, a chance event that we could not explain otherwise. Liposarcomas represent the 4% of the cases. Only one cases has been diagnosed in a patient less than 40 years old. The location sites agree with those

    AIM: To evaluate the predictors of 10-year survival of patients with hepatitis C recurrence. METHODS: Data from 358 patients transplanted between 1989 and 2010 in two Italian transplant centers and with evidence of hepatitis C recurrence were analyzed. A χ2, Fisher’s exact test and Kruskal Wallis’ test were used for categorical and continuous variables, respectively. Survival analysis was performed at 10 years after transplant using the Kaplan-Meier method, and a log-rank test was used to compare groups. A P level less than 0.05 was considered significant for all tests. Multivariate analysis of the predictive role of different variables on 10-year survival was performed by a stepwise Cox logistic regression. RESULTS: The ten-year survival of the entire population was 61.2%. Five groups of patients were identified according to the virological response or lack of a response to antiviral treatment and, among those who were not treated, according to the clinical status (mild hepatitis C recurrence, “too sick to be treated” and patients with comorbidities contraindicating the treatment). While the 10-year survival of treated and untreated patients was not different (59.1% vs 64.7%, P = 0.192), patients with a sustained virological response had a higher 10-year survival rate than both the “non-responders” (84.7% vs 39.8%, P < 0.0001) and too sick to be treated (84.7% vs 0%, P < 0.0001). Sustained virological responders had a survival rate comparable to patients untreated with mild recurrence (84.7% vs 89.3%). A sustained virological response and young donor age were independent predictors of 10-year survival. CONCLUSION: Sustained virological response significantly increased long-term survival. Awaiting the interferon-free regimen global availability, antiviral treatment might be questionable in selected subjects with mild hepatitis C recurrence. PMID:25852276

    The aims of this prospective randomised clinical study were to clinically evaluate a radiopaque, highly filled, hybrid, light-activated resin-based composite for posterior teeth (Occlusin, ICI Dental, Macclesfield, UK and GC Dental, Tokyo, Japan) and compare the performance of restorations placed using rubber dam or cotton roll isolation. One clinician placed 100 (42 Class I and 58 Class II) restorations of the material under investigation. The isolation mode for each restoration was determined randomly: 52 preparations were protected from contamination with cotton rolls and aspiration, and 48 preparations were isolated under rubber dam. At baseline and periodically thereafter (0.5, 1, 2, 3, 4, 5, 6, and 10 years), each composite was evaluated by two practitioners using a modified (USPHS) rating system. After 10 years, 37 restorations were reviewed. The results showed satisfactory clinical performance with and without rubber dam after 10 years. A concern was the number of failures at 10 years due to unsatisfactory proximal contact. The evaluations for the surviving restorations were acceptable but with a large reduction in the percentage with ideal occlusal and proximal anatomy. The 10-year comparison of isolation modes showed no statistically significant differences (Kruskal-Wallis test) for each of the evaluation criteria. Furthermore, survival analysis showed no significant difference between the groups (Mantel-Haenszel method). It was concluded that the 10-year clinical behaviour of the restorations of a posterior composite placed under well-controlled, effective isolation with cotton rolls and aspiration, was not significantly different from the behaviour of restorations placed using rubber dam isolation.

    The objective of the study was to assess the development and evolution of visual and nonvisual hallucinations in patients with Parkinson's disease over 10 years. Hallucinations increase over time, but minimal attention has been placed on nonvisual domains. We studied 60 patients with Parkinson's disease who had never hallucinated at baseline and followed them over 10 years. The Rush Hallucination Inventory monitored frequency and type (visual, auditory, tactile, olfactory) of hallucinations at baseline and after 0.5, 1.5, 4, 6, and 10 years. Descriptive statistics were applied, and general estimating equation modeling assessed longitudinal risks. Over 10 years, visual hallucinations were endorsed by patients more frequently than other sensory modalities. Whereas isolated visual hallucinations dominated the early hallucination profile, visual plus nonvisual hallucinations accounted for progressively higher proportions of hallucinators over 10 years: 0.5 years, 0%; 4 years, 26%; 6 years, 47%; 10 years, 60% (odds ratio, 1.17; confidence interval, 1.01-1.37; P = .04). Once visual plus nonvisual hallucinations developed, the risk of continuing to have multidomain hallucinations was high (odds ratio, 3.67; confidence interval, 1.13-11.93; P = .03). Hallucination severity was highly associated with current visual plus nonvisual hallucinations (odds ratio, 4.06; confidence interval, 2.93-5.61; P < .0001) and the continuation of multidomain hallucinations (odds ratio, 1.58; confidence interval, 1.12-2.24; P = .01). Whereas visual hallucinations in isolation are classic in Parkinson's disease, nonvisual hallucinations emerge over time, and the combination of visual with nonvisual hallucinations predominates in late Parkinson's disease. To capture the breadth and severity of hallucinations in chronically hallucinating patients with Parkinson's disease, screening inventories and practice-based interviews must include questions on both visual and nonvisual components.

  2. Relationship of Blood Pressure With Mortality and Cardiovascular Events Among Hypertensive Patients aged ≥ 60 years in Rural Areas of China: A Strobe-Compliant Study.

    The Eighth Joint National Committee (JNC-8) panel recently recommended a systolic blood pressure (BP) threshold of ≥ 150 mmHg for the initiation of drug therapy and a therapeutic target of <150/90 mmHg in patients ≥ 60 years of age. However, results from some post-hoc analysis of randomized controlled trials and observational studies did not support these recommendations. In the prospective cohort study, 5006 eligible hypertensive patients aged ≥ 60 years from rural areas of China were enrolled for the present analysis. The association between the average follow-up BP and outcomes (all-cause and cardiovascular death, incident coronary heart disease [CHD], and stroke), followed by a median of 4.8 years, were evaluated using Cox proportional hazards models adjusting for other potential confounders. The relationship between BP (systolic or diastolic) showed an increased or J-shaped curve association with adverse outcomes. Compared with the reference group of BP <140/90 mmHg, the risk of all-cause death (hazard ratio [HR]: 2.698; 95% confidence interval [CI]: 1.989-3.659), cardiovascular death (HR: 2.702; 95% CI: 1.855-3.935), incident CHD (HR: 3.263; 95% CI: 2.063-5.161), and stroke (HR: 2.334; 95% CI: 1.559-3.945) was still significantly increased in the group with BP of 140-149/<90 mmHg. Older hypertensive patients with BP of 140-149/<90 mmHg were at higher risk of developing adverse outcomes, implying that lenient BP control of 140-149/<90 mmHg, based on the JNC-8 guidelines, may not be appropriate for hypertensive patients aged ≥ 60 years in rural areas of China.

    Context: Growth hormone (GH) treatment increases bone mineral density (BMD) in women with postmenopausal osteoporosis. Objective: The objective was to report bone data, fractures, and quality of life (QoL) in a 10-year follow-up of women who had received GH for 3 years and compared with controls followed in parallel. Design and Setting: A follow-up of a double-blind, placebo-controlled study conducted at Sahlgrenska University Hospital was performed. Patients: Eighty women aged between 50 and 70 years with osteoporosis and estrogen hormone replacement were studied and compared with an age-matched random population sample of women (n = 120) from the World Health Organization Monitoring of Trends and Determinants in Cardiovascular Disease project (Gothenburg, Sweden). Interventions: Patients were randomized to GH 1.0 U or GH 2.5 U recombinant human GH or placebo sc daily during 3 years. All received calcium 750 mg and vitamin D 400 U and were followed up during 10 years. Main Outcome Measures: BMD and bone mineral content were measured with dual-energy X-ray absorptiometry. QoL was estimated with the 36-item Short Form. Results: GH increased BMD and bone mineral content dose dependently in all regions (P = .01, GH 1.0 U, and P = .0006, GH 2.5 U vs placebo). After 10 years the number of fractures decreased from 56% to 28% (P = .0003) in patients evenly distributed between groups. In controls, fractures increased from 8% to 32% (P = .0008). QoL did not change during GH treatment or during the 10-year follow-up and did not differ compared with controls. Conclusion: GH treatment was beneficial for bone and fracture outcome after 10 years but did not affect the QoL of the women with postmenopausal osteoporosis. PMID:26312576

    A 10-year (1979-1988) integration of Goddard Laboratory for Atmospheres (GLA) general circulation model (GCM) under Atmospheric Model Intercomparison Project (AMIP) is analyzed and compared with observation. The first momentum fields of circulation variables and also hydrological variables including precipitation, evaporation, and soil moisture are presented. Our goals are (1) to produce a benchmark documentation of the GLA GCM for future model improvements; (2) to examine systematic errors between the simulated and the observed circulation, precipitation, and hydrologic cycle; (3) to examine the interannual variability of the simulated atmosphere and compare it with observation; and (4) to examine the ability of the model to capture the major climate anomalies in response to events such as El Nino and La Nina. The 10-year mean seasonal and annual simulated circulation is quite reasonable compared to the analyzed circulation, except the polar regions and area of high orography. Precipitation over tropics are quite well simulated, and the signal of El Nino/La Nina episodes can be easily identified. The time series of evaporation and soil moisture in the 12 biomes of the biosphere also show reasonable patterns compared to the estimated evaporation and soil moisture.

    The 2010 impact goal of the American Heart Association is to reduce death rates from heart disease and stroke by 25% and to lower the prevalence of the leading risk factors by the same proportion. Much of the burden of acute heart disease is initially experienced out of hospital and can be reduced by timely delivery of effective prehospital emergency care. Many patients with an acute myocardial infarction die from cardiac arrest before they reach the hospital. A small proportion of those with cardiac arrest who reach the hospital survive to discharge. Current health surveillance systems cannot determine the burden of acute cardiovascular illness in the prehospital setting nor make progress toward reducing that burden without improved surveillance mechanisms. Accordingly, the goals of this article provide a brief overview of strategies for managing out-of-hospital cardiac arrest. We review existing surveillance systems for monitoring progress in reducing the burden of out-of-hospital cardiac arrest in the United States and make recommendations for filling significant gaps in these systems, including the following: 1. Out-of-hospital cardiac arrests and their outcomes through hospital discharge should be classified as reportable events as part of a heart disease and stroke surveillance system. 2. Data collected on patients' encounters with emergency medical services systems should include descriptions of the performance of cardiopulmonary resuscitation by bystanders and defibrillation by lay responders. 3. National annual reports on key indicators of progress in managing acute cardiovascular events in the out-of-hospital setting should be developed and made publicly available. Potential barriers to action on cardiac arrest include concerns about privacy, methodological challenges, and costs associated with designating cardiac arrest as a reportable event. PMID:18413503

    The present study examines psychiatric symptom levels during a 10-year period in a community sample of mothers of young children. All were identified in the early aftermath of the 1979 Three Mile Island nuclear accident, and followed through the accident's 1989 anniversary. Cluster analysis was used to identify long-term distress profiles during the study period; women's temporal profiles were found to be either (a) stable and at low, clinically nonsignificant levels of distress across all measurement points or (b) at consistently elevated, clinically significant levels that varied with the timing of postaccident events such as the restart of the undamaged reactor and the 10th anniversary. Subsequent multivariate analyses indicated that preaccident characteristics, as well as parameters reflecting respondents' initial involvement with, and reactions to the accident, were important for distinguishing between women within the two temporal profile groups. Implications of the results for both policy formulation and continued research on significant environmental stressors is discussed. PMID:8511662

    2011-01-01

    Objective To determine whether adolescent attitudes towards sports, exercise and fitness predict moderate-to-vigorous physical activity (MVPA) 5 and 10 years later. Method A diverse group of 1902 adolescents participating in Project EAT (Eating and Activity in Teens), reported weekly MVPA and attitudes toward sports, exercise and fitness in EAT-I (1998-99), EAT-II (2003-04), and EAT-III (2008-09). Results Mean MVPA was 6.4, 4.8, and 4.0 hrs/wk at baseline, 5-yr, and 10-yr follow-up, respectively. Attitudes toward sports, exercise, and fitness together predicted MVPA at 5- and 10-years. Among the predictors of 5- and 10-year MVPA, attitude’s effect size, though modest, was comparable to the effect sizes for sports participation and BMI. Adolescents with more-favorable attitudes toward sports, exercise and fitness engaged in approximately 30-40% more weekly MVPA at follow-up (1.7 hr/wk at 5 years and 1.2 hr/wk at 10 years) than those with less-favorable attitudes. Conclusion Adolescents’ exercise-related attitudes predict subsequent MVPA independent of baseline behavior suggesting that youth MVPA promotion efforts may provide long-term benefits by helping youth develop favorable exercise attitudes.

    Objective Pregnancies complicated by diabetes mellitus impair offspring memory functions during infancy and early childhood. The purpose of this study was to investigate the long term consequences of such pregnancies on memory and memory-related brain regions in 10-year-old children. Method Nineteen (19) children of diabetic mothers (CDMs) and thirty-five (35) children of non-diabetic mothers participated in this 10 year follow-up study. Memory performance was assessed using a continuous recognition memory task during which children made old/new judgments in response to pictures of concrete and abstract objects presented after different lags or delays. In addition, the volume of the hippocampal formation was measured using high resolution structural images. Results At 10 years of age, recognition memory performance of CDMs did not differ from children of non-diabetic mothers. Similarly, the volume of the hippocampal formation did not differ between groups. However, the size of the hippocampal formation in CDMs predicted the time those children needed to provide accurate responses in the continuous recognition memory task. Conclusion CDMs do not show memory impairments by 10 years of age, despite evidence for such impairments early in life. However, subtle differences in underlying neural processes may still be present. These results have important implications for long-term cognitive development of CDMs. PMID:26348971

    We aimed to present our experience with carotid angioplasty and stenting (CAS) and to document how the technique evolved over the last decade (1997-2007). A retrospective study of 333 patients (259 men; median age, 69 years) who underwent 336 CAS procedures. Of these, 118 (35%) patients were symptomatic and 164 (49%) lesions involved the left carotid bifurcation. The first 163 patients received a balloon-expandable stent, whereas the remaining 173 received a self-expandable one. Cerebral protection devices were used in the last 84 (25%) procedures. Access was via the femoral artery in all but six cases, in which direct puncture of the common carotid was necessary. The left common carotid originated from the innominate artery in 18 cases (5%). Conversion to open endarterectomy was necessary in two patients due to inability to remove the filter. Perioperative neurological events included stroke in 6 patients (1.8%), transient ischemic attack in 15 (4.5%), and hyperperfusion syndrome in 10 (3.0%). Three patients died during the first 30 days. As a result, the mortality and the combined stroke/death rate were 0.9 and 2.4%, respectively, with no differences between symptomatic and asymptomatic patients. Bradycardia was noted in 48 patients (14%), and hypotension in 45 (13%). Univariate analysis identified hypertension (P = 0.03), hyperlipidemia (P = 0.02), and current or ex-smoking (P = 0.02) as significant risk factors for death/stroke. On multivariate analysis using logistic regression, only hyperlipidemia [odds ratio (OR), 53.90; 95% confidence interval (CI), 4.19-693.47; P = 0.002] and current or ex-smoking (OR, 63.84; 95% CI,: 4.80-848.68; P = 0.001) remained statistically significant. In conclusion, CAS can be performed safely and effectively, with acceptable mortality, stroke/death, and cardiovascular complication rates. Although technological advances (stent design, cerebral protection devices), perioperative pharmacological management, and increasing experience

    Residual cardiovascular risk and failure of high density lipoprotein cholesterol raising treatment have refocused interest on targeting hypertriglyceridemia. Hypertriglyceridemia, triglyceride-rich lipoproteins, and remnant cholesterol have demonstrated to be important risk factors for cardiovascular disease; this has been demonstrated in experimental, genetic, and epidemiological studies. Fibrates can reduce cardiovascular event rates with or without statins. High dose omega-3 fatty acids continue to be evaluated and new specialized targeting treatment modulating triglyceride pathways, such as inhibition of apolipoprotein C-III and angiopoietin-like proteins, are being tested with regard to their effects on lipid profiles and cardiovascular outcomes. In this review, we will discuss the role of hypertriglyceridemia, triglyceride-rich lipoproteins and remnant cholesterol on cardiovascular disease, and the potential implications for treatment stargeting hypertriglyceridemia.

    2016-07-01

    Chronic kidney disease, defined as reduced glomerular filtration rate (estimated using serum creatinine- and/or serum cystatin C-based equations) or excess urinary protein excretion, affects approximately 13% of adult Americans and is linked to a variety of clinical complications. Although persons with end-stage renal disease requiring chronic dialysis therapy experience a substantially high cardiovascular burden, whether mild-to-moderate chronic kidney disease is an independent risk factor for fatal and nonfatal cardiovascular events has been more controversial. This review evaluates the current evidence about the clinical and subclinical cardiovascular consequences associated with chronic kidney disease of varying levels of severity. In addition, it discusses the predictors of adverse cardiovascular outcomes while also focusing on recent insights into the relationships between chronic kidney disease and cardiovascular disease from the Chronic Renal Insufficiency Cohort study, a large current prospective cohort study of adults from across the spectrum of chronic kidney disease.

    This study evaluated the long-term clinical performance of a self-etching adhesive system, Clearfil Liner Bond 2. Two operators placed a total of 87 restorations among 42 patients. Carious dentin was identified with the help of Caries Detector and was removed using only a low speed round bur. Clearfil Liner Bond 2 was applied following the manufacturer's directions, and the resin composite was then placed. The number of restorations placed by cavity classification were: 8-Class I, 11-Class II, 21-Class III, 2-Class IV and 45-Class V. The restorations were evaluated in 5 categories according to modified USPHS criteria: pulpal response, marginal integrity, marginal discoloration, retention and secondary caries. Assessments were done at baseline, immediately after placement and at 6-months and 1, 5, 7 and 10 years. Recall rates at each assessment period were 83.9% (6-months), 82.8% (1 year), 59.8% (5 years), 77.0% (7 years) and 50.6% (10 years). In terms of assessment categories, there were no recorded sensitivity, retention loss or secondary caries at any of the five recall periods. At the 10-year assessment, 40 out of 44 restorations (90.9%) were rated Bravo for marginal integrity and 39 restorations (88.6%) were rated Bravo for marginal discoloration (Wilcoxon signed-ranks test p < 0.05). This data demonstrates the retention rate and pulpal response of the self-etching adhesive system Clearfil Liner Bond 2 was excellent at 10 years. Most cases showed slight marginal changes during clinical function; however, these changes were not clinically severe by USPHS criteria. These data demonstrate that placement of the Clearfil Liner Bond 2 self-etching adhesive system was demonstrated to be acceptable for the clinical restoration of human teeth following 10 years of clinical function.

    2012-01-01

    OBJECTIVE The Diabetes Prevention Program (DPP) and its Outcomes Study (DPPOS) demonstrated that either intensive lifestyle intervention or metformin could prevent type 2 diabetes in high-risk adults for at least 10 years after randomization. We report the 10-year within-trial cost-effectiveness of the interventions. RESEARCH DESIGN AND METHODS Data on resource utilization, cost, and quality of life were collected prospectively. Economic analyses were performed from health system and societal perspectives. RESULTS Over 10 years, the cumulative, undiscounted per capita direct medical costs of the interventions, as implemented during the DPP, were greater for lifestyle ($4,601) than metformin ($2,300) or placebo ($769). The cumulative direct medical costs of care outside the DPP/DPPOS were least for lifestyle ($24,563 lifestyle vs. $25,616 metformin vs. $27,468 placebo). The cumulative, combined total direct medical costs were greatest for lifestyle and least for metformin ($29,164 lifestyle vs. $27,915 metformin vs. $28,236 placebo). The cumulative quality-adjusted life-years (QALYs) accrued over 10 years were greater for lifestyle (6.81) than metformin (6.69) or placebo (6.67). When costs and outcomes were discounted at 3%, lifestyle cost $10,037 per QALY, and metformin had slightly lower costs and nearly the same QALYs as placebo. CONCLUSIONS Over 10 years, from a payer perspective, lifestyle was cost-effective and metformin was marginally cost-saving compared with placebo. Investment in lifestyle and metformin interventions for diabetes prevention in high-risk adults provides good value for the money spent. PMID:22442395

    Background. The NCEP metabolic syndrome (MetS) is a combination of dichotomized interrelated risk factors from predominantly Caucasian populations. We propose a continuous MetS score based on principal component analysis (PCA) of the same risk factors in a multiethnic cohort and compare prediction of incident CVD events with NCEP MetS definition. Additionally, we replicated these analyses in the Health, Aging, and Body composition (Health ABC) study cohort. Methods and Results. We performed PCA of the MetS elements (waist circumference, HDL, TG, fasting blood glucose, SBP, and DBP) in 2610 Caucasian Americans, 801 Chinese Americans, 1875 African Americans, and 1494 Hispanic Americans in the multiethnic study of atherosclerosis (MESA) cohort. We selected the first principal component as a continuous MetS score (MetS-PC). Cox proportional hazards models were used to examine the association between MetS-PC and 5.5 years of CVD events (n = 377) adjusting for age, gender, race, smoking and LDL-C, overall and by ethnicity. To facilitate comparison of MetS-PC with the binary NCEP definition, a MetS-PC cut point was chosen to yield the same 37% prevalence of MetS as the NCEP definition (37%) in the MESA cohort. Hazard ratio (HR) for CVD events were estimated using the NCEP and Mets-PC-derived binary definitions. In Cox proportional models, the HR (95% CI) for CVD events for 1-SD (standard deviation) of MetS-PC was 1.71 (1.54–1.90) (P < 0.0001) overall after adjusting for potential confounders, and for each ethnicity, HRs were: Caucasian, 1.64 (1.39–1.94), Chinese, 1.39 (1.06–1.83), African, 1.67 (1.37–2.02), and Hispanic, 2.10 (1.66-2.65). Finally, when binary definitions were compared, HR for CVD events was 2.34 (1.91–2.87) for MetS-PC versus 1.79 (1.46–2.20) for NCEP MetS. In the Health ABC cohort, in a fully adjusted model, MetS-PC per 1-SD (Health ABC) remained associated with CVD events (HR = 1.21, 95%CI 1.12–1.32) overall, and for each ethnicity

    Study Design Systematic review. Clinical Questions (1) Has the proportion and number of randomized controlled trials (RCTs) as an indicator of quality of evidence regarding lumbar fusion increased over the past 10 years? (2) Is there a difference in the proportion of RCTs among the four primary fusion diagnoses (degenerative disk disease, spondylolisthesis, deformity, and adjacent segment disease) over the past 10 years? (3) Is there a difference in the type and quality of clinical outcomes measures reported among RCTs over time? (4) Is there a difference in the type and quality of adverse events measures reported among RCTs over time? (5) Are there changes in fusion surgical approach and techniques over time by diagnosis over the past 10 years? Methods Electronic databases and reference lists of key articles were searched from January 1, 2004, through December 31, 2013, to identify lumbar fusion RCTs. Fusion studies designed specifically to evaluate recombinant human bone morphogenetic protein-2 or other bone substitutes, revision surgery studies, nonrandomized comparison studies, case reports, case series, and cost-effectiveness studies were excluded. Results Forty-two RCTs between January 1, 2004, and December 31, 2013, met the inclusion criteria and form the basis for this report. There were 35 RCTs identified evaluating patients diagnosed with degenerative disk disease, 4 RCTs evaluating patients diagnosed with degenerative spondylolisthesis, and 3 RCTs evaluating patients with a combination of degenerative disk disease and degenerative spondylolisthesis. No RCTs were identified evaluating patients with deformity or adjacent segment disease. Conclusions This structured review demonstrates that there has been an increase in the available clinical database of RCTs using patient-reported outcomes evaluating the benefit of lumbar spinal fusion for the diagnoses of degenerative disk disease and degenerative spondylolisthesis.

    Air pollution is increasingly recognized as an important and modifiable determinant of cardiovascular diseases in urban communities. The potential detrimental effects are both acute and chronic having a strong impact on morbidity and mortality. The acute exposure to pollutants has been linked to adverse cardiovascular events such as myocardial infarction, heart failure and life-threatening arrhythmias. The long-terms effects are related to the lifetime risk of death from cardiac causes. The WHO estimates that air pollution is responsible for 3 million premature deaths each year. The evidence supporting these data is very strong nonetheless, epidemiologic and observational data have the main limitation of imprecise measurements. Moreover, the lack of clinical experimental models makes it difficult to demonstrate the individual risk. The other limitation is related to the lack of a clear mechanism explaining the effects of pollution on cardiovascular mortality. In the present review we will explore the epidemiological, clinical and experimental evidence of the effects of ozone on cardiovascular diseases. The pathophysiologic consequences of air pollutant exposures have been extensively investigated in pulmonary systems, and it is clear that some of the major components of air pollution (e.g. ozone and particulate matter) can initiate and exacerbate lung disease in humans 1. It is possible that pulmonary oxidant stress mediated by particulate matter and/or ozone (O3) exposure can result in downstream perturbations in the cardiovasculature, as the pulmonary and cardiovascular systems are intricately associated, and it is well documented that specific environmental toxins (such as tobacco smoke 2) introduced through the lungs can initiate and/or accelerate cardiovascular disease development. Indeed, several epidemiologic studies have proved that there is an association between PM and O3 and the increased incidence of cardiovascular morbidity and mortality 3. Most of the

    Total hip arthroplasty is a common and important treatment for osteoarthritis patients. Long-term cardiovascular effects elicited by osteoarthritis or the implant itself remain unknown. The purpose of the present study was to determine if there is an increased risk of late cardiovascular mortality and morbidity after total hip arthroplasty surgery.A nationwide matched cohort study with data on 91,527 osteoarthritis patients operated on, obtained from the Swedish Hip Arthroplasty Register. A control cohort (n = 270,688) from the general Swedish population was matched 1:3 to each case by sex, age, and residence. Mean follow-up time was 10 years (range, 7-21).The exposure was presence of a hip replacement for more than 5 years. The primary outcome was cardiovascular mortality after 5 years. Secondary outcomes were total mortality and re-admissions due to cardiovascular events.During the first 5 to 9 years, the arthroplasty cohort had a lower cardiovascular mortality risk compared with the control cohort. However, the risk in the arthroplasty cohort increased over time and was higher than in controls after 8.8 years (95% confidence interval [CI] 7.0-10.5). Between 9 and 13 years postoperatively, the hazard ratio was 1.11 (95% CI 1.05-1.17). Arthroplasty patients were also more frequently admitted to hospital for cardiovascular reasons compared with controls, with a rate ratio of 1.08 (95% CI 1.06-1.11).Patients with surgically treated osteoarthritis of the hip have an increased risk of cardiovascular morbidity and mortality many years after the operation when compared with controls.

    Introduction Managing postoperative pain in patients undergoing minimally invasive pectus excavatum repair (Nuss procedure) is challenging but essential in facilitating ambulation and minimizing the length of stay. Although multiple epidural regimens with varying opioids are presently used for pain management, there is currently no clinical consensus regarding which epidural regimen provides the best analgesia outcomes with the fewest side effects. This 10-year retrospective cohort study was performed to compare the quality of analgesia and the incidence of side effects associated with the three most common epidural regimens used at a tertiary care children’s hospital, in patients undergoing the Nuss procedure. Methods Seventy-two pediatric patients were identified as having been treated with one of three epidural regimens for postoperative pain management following the Nuss procedure: Group A (n=12) received 0.125% bupivacaine and 5 µg/mL fentanyl, Group B (n=21) received 0.125% bupivacaine and 10 µg/mL hydromorphone, and Group C (n=39) received 0.1% ropivacaine and 20 µg/mL hydromorphone. Our primary outcome was maximal daily pain scores (numerical rating scale 0–10), with an analytical focus on postoperative day 1 scores. The primary outcome was analyzed using linear regression. The secondary outcomes included the length of stay, side-effect profiles as reflected by the number of treatments for nausea and pruritus, pain scores according to epidural site insertion, occurrence of breakthrough pain, and presence of severe pain throughout their hospital stay. Secondary outcomes were analyzed using linear or logistic regression adjusted for pain scores at baseline. The criterion for statistical significance was set a priori at alpha =0.05. Results Group A had significantly higher day-1 pain scores (score 5.42/10) than Group B (4.52/10; P=0.030) and Group C (4.49/10; P=0.015) after adjusting for baseline pain and age. No significant difference in maximum daily

    OBJECTIVE To analyze the relationships between cardiovascular complications and geriatric scale scores in French elderly (≥70 years of age) type 2 diabetic patients at inclusion in the GERODIAB cohort. RESEARCH DESIGN AND METHODS GERODIAB is the first French multicenter, prospective, observational survey designed to analyze the influence of glycemic control on morbidity/mortality in type 2 diabetic patients aged ≥70 years during a 5-year follow-up period. This study analyzed the relationships between classical macroangiopathic complications and geriatric scale scores in 987 patients at baseline, using bivariate and multivariate analyses. RESULTS Cardiac ischemia (31.2%) was significantly associated with impaired activities of daily living (ADL) scores (P < 0.001). Stepwise logistic regression included hypercholesterolemia, ADL, sex, and hypertension successively (70.3% concordance; P < 0.001). Heart failure (10.1%) was associated with impaired Mini Mental State Examination (MMSE), instrumental ADL (IADL) (P < 0.05), and ADL scores (P < 0.001). With the logistic model, waist circumference, age, and HDL cholesterol were significant factors (70.7% concordance; P < 0.001). Arterial disease of the lower limbs (25.6%) was associated with impaired IADL and ADL scores (P < 0.001). Significant factors using the logistic model were duration of diabetes, IADL score, hypertension, and sex (62.8% concordance; P < 0.001). Cerebral ischemia (15.8%) was associated with impaired MMSE, Mini Nutritional Assessment, ADL, and IADL scores (P < 0.01). IADL, sex, hypertension, and ADL were included in the logistic model successively (65.6% concordance; P < 0.001). CONCLUSIONS In this specific population, impaired geriatric scale scores were found to be associated with classical macrovascular complications, notably using multivariate analyses. This suggests the benefits of thorough screening and management of cognitive and functional decline in elderly type 2 diabetic patients.

    A 31-year-old female with a history of lupus nephritis on Hydroxychloroquine, Prednisone, and Mycophenolate Mofetil (MMF) for 10 years presented to the hospital for ankle swelling. On day four, she started to have severe, nonbloody, watery diarrhea with abdominal distension and tenderness. Stool PCR was negative for C. difficile. CT abdomen/pelvis showed gaseous distension of the colon without any obstruction. Flexible sigmoidoscopy revealed a normal looking mucosa. Histopathology showed crypt atrophy and increased crypt apoptosis, consistent with MMF colitis. The diarrhea resolved three days after stopping MMF. Although generally well tolerated, diarrhea is a common side effect of MMF. Most cases occur in the first six months of starting MMF. This case is unique because it describes MMF colitis in lupus after more than 10 years. Thus, MMF colitis should be considered as a differential in patients taking it, regardless of the duration of use.

    This study examined (a) the role of avoidance coping in prospectively generating both chronic and acute life stressors and (b) the stress-generating role of avoidance coping as a prospective link to future depressive symptoms. Participants were 1,211 late-middle-aged individuals (500 women and 711 men) assessed 3 times over a 10-year period. As predicted, baseline avoidance coping was prospectively associated with both more chronic and more acute life stressors 4 years later. Furthermore, as predicted, these intervening life stressors linked baseline avoidance coping and depressive symptoms 10 years later, controlling for the influence of initial depressive symptoms. These findings broaden knowledge about the stress-generation process and elucidate a key mechanism through which avoidance coping is linked to depressive symptoms. PMID:16173853

    Advanced Trauma Life Support (ATLS) programs are recognized as the standard educational trauma program worldwide. Data suggest that ATLS has a positive impact on the value of trauma care. The ATLS Hungary program has been started in 2005, celebrating its 10-year anniversary this year. In the present brief communication a brief overview is provided on the program.Student evaluation and statistical data about the participants were collected throughout the 10-year history of the Hungarian program.Student evaluation shows a high level of satisfaction amongst the participating doctors. Most participants are working in higher level centers. The Hungarian program shows good quality according to the participants. Establishing at least one new center is crucial to be able to provide the course for every professional interested in it or required to take it. PMID:27162927

    A 10-year review (1987-1996) of injuries sustained to the spine and spinal cord in rugby players with resultant paralysis has been undertaken. This article reviews that the incidence of serious rugby spine and spinal cord injuries in South Africa has increased over the 10-year period reviewed, despite stringent new rules instituted in an attempt to decrease the incidence of these injuries. The mechanisms of injury, as previously reported, remain the same as well as the phases of game responsible for injury of the tight scrum, tackle, rucks, and mauls. Two new observations are reported: the first is related to the occurrence of spinal cord concussion with transient paralysis, and the second is related to the increased incidence of osteoarthritis of the cervical spine in rugby players.
