    To determine the incidence of coronary heart disease (CHD) events in an urban Aboriginal population. Cohort study of 906 Aboriginal people without CHD from 998 who had undergone risk-factor assessment in the Perth Aboriginal Atherosclerosis Risk Study (PAARS) in 1998-1999. PAARS cohort data were electronically linked to a range of databases that included Western Australian hospital morbidity data and death registry data. We analysed data from January 1980 to December 2006 to identify previous admissions for CHD from 1980 to baseline (1998-1999) and new events from baseline to 2006. First CHD event (hospital admission or death). There were 891 linked records for the 906 participants without previous CHD. The event rate was 12.6/1000 person-years (95% CI, 10.2-15.6/1000 person-years). Annual CHD event rates ranged from 8 to 18/1000 person-years. After adjustment for age (sex was not associated with the risk factors assessed), factors associated with risk of a CHD event in the PAARS cohort were a history of diabetes, overweight or obesity (indicated by body mass index), smoking, and hypertension, but not waist circumference. People with these risk factors were 1.9-2.7 times more likely to experience a CHD event. Compared with previously published information from a remote Aboriginal community in the Northern Territory, the incidence of CHD events among urban-dwelling Aboriginal people was not significantly different (P > 0.05 overall and for subgroups defined by age and sex). City-dwelling Aboriginal Australians have an incidence of CHD events comparable to that of Aboriginal people living in remote northern Australia.

    Full Text Available BACKGROUND: The role of coffee intake as a risk factor for coronary heart disease (CHD has been debated for decades. We examined whether the relationship between coffee intake and incidence of CHD events is dependent on the metabolism of circulating catecholamines, as determined by functional polymorphism of the catechol-O-methyltransferase (COMT gene. METHODOLOGY/PRINCIPAL FINDINGS: In a cohort of 773 men who were 42 to 60 years old and free of symptomatic CHD at baseline in 1984-89, 78 participants experienced an acute coronary event during an average follow-up of 13 years. In logistic regression adjusting for age, smoking, family history of CHD, vitamin C deficiency, blood pressure, plasma cholesterol concentration, and diabetes, the odds ratio (90% confidence interval comparing heavy coffee drinkers with the low activity COMT genotype with those with the high activity or heterozygotic genotypes was 3.2 (1.2-8.4. Urinary adrenaline excretion increased with increasing coffee intake, being over two-fold in heavy drinkers compared with nondrinkers (p = 0.008 for trend. CONCLUSIONS/SIGNIFICANCE: Heavy coffee consumption increases the incidence of acute coronary events in men with low but not high COMT activity. Further studies are required to determine to which extent circulating catecholamines mediate the relationship between coffee intake and CHD.

    Background We examined whether type of menopause affects sex differences in coronary heart disease (CHD) events and whether the impact is similar in blacks and whites. Methods and Results Participants were enrolled in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) cohort between 2003 and 2007 without CHD at baseline (n=23 086). Cox regression models were used to calculate the hazard of incident nonfatal CHD (definite or probable myocardial infarction) and acute CHD death, adjusting for age, age at last menstrual period menopause (hazard ratio [HR], 0.45; 95% confidence interval [CI], 0.31, 0.66) and surgical menopause (HR, 0.65; 95% CI, 0.42, 0.99) had a reduced hazard of nonfatal events, compared to white men. Black women in natural menopause (HR, 0.69; 95% CI, 0.47, 1.03), but not surgical menopause (HR, 0.81; 95% CI, 0.51, 1.29), had a marginally reduced hazard of nonfatal events, compared to black men. Women had lower risk of acute CHD death than men regardless of their menopause type and race. Conclusions Sex differences in the risk of incident CHD events were larger among whites than blacks and varied by type of menopause. Women consistently had a lower risk of incident CHD death than men, but the magnitude of sex differences was greater in whites than blacks for nonfatal events, regardless of menopause type.

    Full Text Available Abstract Of the associations between dietary elements and coronary artery disease (CAD, the greatest body of evidence deals with the beneficial effect of reducing the dietary intake of saturated fatty acids and cholesterol. Furthermore, it is well established, on the basis of convincing evidence, that reduction in serum total cholesterol results in reduction in coronary morbidity and mortality, as well as in regression of other atherosclerotic manifestations.In fact, dietary intervention studies revealed that it is possible to reduce the incidence of coronary death and nonfatal myocardial infarction, as well as manifestations of atherosclerosis in cerebral and peripheral arteries, by reducing dietary intake of saturated fat and cholesterol. In two recently reported dietary interventions the incidence of coronary events, especially coronary mortality, and total mortality were reduced by increased intake of n-3 long-chain polyunsaturated fatty acids and by a modification of the diet toward a Mediterranean-type diet (rich in α-linolenic acid. In addition to those findings, the potential efficacy of the dietary newcomers phytostanol and phytosterol esters on reducing coronary incidence is discussed in the present review.

    Hypertension is an atherosclerosis factor and is associated with cardiovascular risk. We investigated the relationship between hypertension and the presence, extent, and severity of coronary atherosclerosis in coronary computed tomographic angiography and cardiac events risk. Of 17 181 patients enrolled in the CONFIRM registry (Coronary CT Angiography Evaluation for Clinical Outcomes: An International Multicenter Registry) who underwent ≥64-detector row coronary computed tomographic angiography, we identified 14 803 patients without known coronary artery disease. Of these, 1434 hypertensive patients were matched to 1434 patients without hypertension. Major adverse cardiac events risk of hypertension and non-hypertensive patients was evaluated with Cox proportional hazards models. The prognostic associations between hypertension and no-hypertension with increasing degree of coronary stenosis severity (nonobstructive or obstructive ≥50%) and extent of coronary artery disease (segment involvement score of 1-5, >5) was also assessed. Hypertension patients less commonly had no coronary atherosclerosis and more commonly had nonobstructive and 1-, 2-, and 3-vessel disease than the no-hypertension group. During a mean follow-up of 5.2±1.2 years, 180 patients experienced cardiac events, with 104 (2.0%) occurring in the hypertension group and 76 (1.5%) occurring in the no-hypertension group (hazard ratios, 1.4; 95% confidence intervals, 1.0-1.9). Compared with no-hypertension patients without coronary atherosclerosis, hypertension patients with no coronary atherosclerosis and obstructive coronary disease tended to have higher risk of cardiac events. Similar trends were observed with respect to extent of coronary artery disease. Compared with no-hypertension patients, hypertensive patients have increased presence, extent, and severity of coronary atherosclerosis and tend to have an increase in major adverse cardiac events. © 2017 American Heart Association, Inc.

    Few studies have used individual person data to study whether contemporary trends in the incidence of coronary heart disease are associated with changes in modifiable coronary risk factors. We identified 29 582 healthy men and women ≥25 years of age who participated in 3 population surveys conducted between 1994 and 2008 in Tromsø, Norway. Age- and sex-adjusted incidence rates were calculated for coronary heart disease overall, out-of-hospital sudden death, and hospitalized ST-segment-elevation and non-ST-segment-elevation myocardial infarction. We measured coronary risk factors at each survey and estimated the relationship between changes in risk factors and changes in incidence trends. A total of 1845 participants had an incident acute coronary heart disease event during 375 064 person-years of follow-up from 1994 to 2010. The age- and sex-adjusted incidence of total coronary heart disease decreased by 3% (95% confidence interval, 2.0-4.0; Pcoronary risk factors accounted for 66% (95% confidence interval, 48-97; Pcoronary heart disease. Favorable changes in cholesterol contributed 32% to the decline, whereas blood pressure, smoking, and physical activity each contributed 14%, 13%, and 9%, respectively. We observed a substantial decline in the incidence of coronary heart disease that was driven by reductions in out-of-hospital sudden death and hospitalized ST-segment-elevation myocardial infarction. Changes in modifiable coronary risk factors accounted for 66% of the decline in coronary heart disease events. © 2015 American Heart Association, Inc.

    Background: Epidemiologic evidence for work stress as a risk factor for coronary heart disease is mostly based on a single measure of stressful work known as job strain, a combination of high demands and low job control. We examined whether a complementary stress measure that assesses an imbalance between efforts spent at work and rewards received predicted coronary heart disease. Methods: This multicohort study (the “IPD-Work” consortium) was based on harmonized individual-level data from 11 European prospective cohort studies. Stressful work in 90,164 men and women without coronary heart disease at baseline was assessed by validated effort–reward imbalance and job strain questionnaires. We defined incident coronary heart disease as the first nonfatal myocardial infarction or coronary death. Study-specific estimates were pooled by random effects meta-analysis. Results: At baseline, 31.7% of study members reported effort–reward imbalance at work and 15.9% reported job strain. During a mean follow-up of 9.8 years, 1,078 coronary events were recorded. After adjustment for potential confounders, a hazard ratio of 1.16 (95% confidence interval, 1.00–1.35) was observed for effort–reward imbalance compared with no imbalance. The hazard ratio was 1.16 (1.01–1.34) for having either effort–reward imbalance or job strain and 1.41 (1.12–1.76) for having both these stressors compared to having neither effort–reward imbalance nor job strain. Conclusions: Individuals with effort–reward imbalance at work have an increased risk of coronary heart disease, and this appears to be independent of job strain experienced. These findings support expanding focus beyond just job strain in future research on work stress. PMID:28570388

    The population analysis of cardiovascular risk and non-risk genetic variation can help to identify adaptive or random demographic processes that shaped coronary incidence variation across geography. In this study, 114 single nucleotide polymorphisms and 17 tandem repeat polymorphisms from Nitric Oxide Synthases (NOS) regions were analyzed in 1686 individuals from 35 populations from Europe, North Africa, and the Middle East. NOS genes encode for key enzymes on nitric oxide availability, which is involved in several cardiovascular processes. These genetic variations were used to test for selection and to infer the population structure of NOS regions. Moreover, we tested whether the variation in the incidence of coronary events and in the levels of classical risk factors in 11 of these European populations could be explained by the population structure estimates. Our results supported, first, the absence of clear signs of selection for NOS genetic variants associated with cardiovascular diseases, and second, the presence of a continuous genetic pattern of variation across European and North African populations without a Mediterranean barrier for gene flow. Finally, population structure estimates from NOS regions are closely correlated with coronary event rates and classical risk parameters (explaining 39-98%) among European populations. Our results reinforce the hypothesis that genetic bases of cardiovascular diseases and associated complex phenotypes could be geographically shaped by random demographic processes. © 2016 Wiley Periodicals, Inc.

    Noncardiac surgery after percutaneous coronary intervention (PCI) has been reported to be carrying high risk for both ischemic and bleeding complications. However, there has been no report comparing the incidence and outcomes of surgical procedures after coronary artery bypass grafting (CABG) with those after PCI. Among 14 383 patients undergoing first coronary revascularization (PCI, n=12 207; CABG, n=2176) enrolled in the Coronary Revascularization Demonstrating Outcome Study in Kyoto (CREDO-Kyoto) PCI/CABG Registry Cohort-2, surgical procedures were performed more frequently after CABG (n=560) than after PCI (n=2398; cumulative 3-year incidence: 27% versus 22%; unadjusted PPCI groups (cumulative incidence: 3.1% versus 3.2%; unadjusted P=0.9; adjusted hazard ratio, 0.97; 95% confidence interval, 0.47-1.89; P=0.9). The risk for the primary bleeding outcome measure (moderate or severe bleeding by Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries classification) was lower in the CABG groups than in the PCI group (cumulative incidence: 1.3% versus 2.6%; unadjusted P=0.07; adjusted hazard ratio, 0.36; 95% confidence interval, 0.12-0.87; P=0.02). There were no interactions between the timing of surgery and the types of coronary revascularization (CABG/PCI) for both ischemic and bleeding outcomes. Surgical procedures were performed significantly more frequently after CABG than after PCI, particularly PCI were associated with similar risk for ischemic events and lower risk for bleeding events, regardless of the timing after coronary revascularization. © 2014 American Heart Association, Inc.

    Computed tomography (CT) allows estimation of coronary artery calcium (CAC) progression. We evaluated several progression algorithms in our unselected, population-based cohort for risk prediction of coronary and cardiovascular events. In 3281 participants (45-74 years of age), free from cardiovascular disease until the second visit, risk factors, and CTs at baseline (b) and after a mean of 5.1 years (5y) were measured. Hard coronary and cardiovascular events, and total cardiovascular events including revascularization, as well, were recorded during a follow-up time of 7.8±2.2 years after the second CT. The added predictive value of 10 CAC progression algorithms on top of risk factors including baseline CAC was evaluated by using survival analysis, C-statistics, net reclassification improvement, and integrated discrimination index. A subgroup analysis of risk in CAC categories was performed. We observed 85 (2.6%) hard coronary, 161 (4.9%) hard cardiovascular, and 241 (7.3%) total cardiovascular events. Absolute CAC progression was higher with versus without subsequent coronary events (median, 115 [Q1-Q3, 23-360] versus 8 [0-83], P value of baseline CT and risk assessment in terms of C-statistic or integrated discrimination index, especially for total cardiovascular events. However, CAC progression did not improve models including CAC 5y and 5-year risk factors. An excellent prognosis was found for 921 participants with double-zero CAC b =CAC 5y =0 (10-year coronary and hard/total cardiovascular risk: 1.4%, 2.0%, and 2.8%), which was for participants with incident CAC 1.8%, 3.8%, and 6.6%, respectively. When CAC b progressed from 1 to 399 to CAC 5y ≥400, coronary and total cardiovascular risk were nearly 2-fold in comparison with subjects who remained below CAC 5y =400. Participants with CAC b ≥400 had high rates of hard coronary and hard/total cardiovascular events (10-year risk: 12.0%, 13.5%, and 30.9%, respectively). CAC progression is associated with

    The volume and density of coronary artery calcium (CAC) both independently predict cardiovascular disease (CVD) beyond standard risk factors, with CAC density inversely associated with incident CVD after accounting for CAC volume. We tested the hypothesis that ascending thoracic aorta calcium (ATAC) volume and density predict incident CVD events independently of CAC. The Multi-Ethnic Study of Atherosclerosis (MESA) is a prospective cohort study of participants without clinical CVD at baseline. ATAC and CAC were measured from baseline cardiac computed tomography (CT). Cox regression models were used to estimate the associations of ATAC volume and density with incident coronary heart disease (CHD) events and CVD events, after adjustment for standard CVD risk factors and CAC volume and density. Among 6811 participants, 234 (3.4%) had prevalent ATAC and 3395 (49.8%) had prevalent CAC. Over 10.3 years, 355 CHD and 562 CVD events occurred. One-standard deviation higher ATAC density was associated with a lower risk of CHD (HR 0.48 [95% CI 0.29-0.79], pdensity was inversely associated with incident CHD and CVD after adjustment for CVD risk factors and CAC volume and density.

    Understanding the determinants of persistent smoking after a coronary event constitutes the basis of modelling interventions of smoking cessation in secondary prevention programs. We aim to identify the potentially modifiable medical, sociodemographic and psychosocial factors, comprising the study factors, associated with unfavourable risk factor control after CHD events. A cross-sectional explorative study used logistic regression analysis to investigate the association between study factors and smoking status in 1083 patients hospitalized with myocardial infarction and/or coronary revascularization. Hospital record data, a self-report questionnaire, clinical examination and blood samples were applied. At the index hospitalization, 390 patients were smoking and at follow-up after 2-36 months 167 (43%) of these had quit, while 230 reported persistent smoking. In adjusted analyses, unemployed or disability benefits (Odds ratio (OR) 4.1), low education (OR 3.5), longer smoking duration (OR 2.3) and not having ST-elevation myocardial infarction (STEMI) as index event (OR 2.3) were significantly associated with persistent smoking. Psychosocial factors at follow-up were not associated with persistent smoking. Smokers reported high motivation for cessation, with 68% wanting help to quit. Only 42% had been offered nicotine replacement therapy or other cessation aids. Smokers rated use of tobacco as the most important cause of their coronary disease (6.8 on a 1-10 Likert scale). Low socioeconomic status, prior duration of smoking, and not having STEMI as index event were associated with persisting smoking. Persistent smokers in this study seem to have an acceptable risk perception and were motivated to cease smoking, but needed assistance through cessation programs including prescription of pharmacological aids.

    The aim of this study was to determine whether post-traumatic stress disorder (PTSD) is associated with coronary heart disease (CHD) using a prospective twin study design and objective measures of CHD. It has long been hypothesized that PTSD increases the risk of CHD, but empirical evidence using objective measures is limited. We conducted a prospective study of middle-aged male twins from the Vietnam Era Twin Registry. Among twin pairs without self-reported CHD at baseline, we selected pairs discordant for a lifetime history of PTSD, pairs discordant for a lifetime history of major depression, and pairs without either condition. All underwent a clinic visit after a median follow-up of 13 years. Outcomes included clinical events (myocardial infarction, other hospitalizations for CHD and coronary revascularization) and quantitative measures of myocardial perfusion by [(13)N] ammonia positron emission tomography, including a stress total severity score and coronary flow reserve. A total of 562 twins (281 pairs) with a mean age of 42.6 years at baseline were included in this study. The incidence of CHD was more than double in twins with PTSD (22.6%) than in those without PTSD (8.9%; p Stress total severity score was significantly higher (+95%, p = 0.001) and coronary flow reserve was lower (-0.21, p = 0.02) in twins with PTSD than in those without PTSD, denoting worse myocardial perfusion. Associations were only mildly attenuated in 117 twin pairs discordant for PTSD. Among Vietnam-era veterans, PTSD is a risk factor for CHD. Copyright © 2013 American College of Cardiology Foundation.

The aim of this study was to investigate the incidence and severity of CAD in patients with AF.From January 2005 until December 2009, we included 261 consecutive patients admitted to hospital with paroxysmal, persistent or permanent AF in this prospective study. All patients underwent coronary angiography and the Framingham risk score (FRS was calculated. Patients with previously diagnosed or previously excluded CAD were excluded.The overall incidence of CAD in patients presenting with AF was 34%; in patients >70 years, the incidence of CAD was 41%. The incidence of patients undergoing a percutaneous coronary intervention (PCI or coronary artery bypass graft (CABG was 21%. Patients with CAD were older (73±8 years vs 68±10 years, p = 0.001, had significantly more frequent hypercholesterolemia (60% vs 30%, p<0.001, were more frequent smokers (26% vs 13%, p = 0.017 and suffered from angina more often (37% vs 2%, p<0.001. There was a significant linear trend among the FRS categories in percentage and the prevalence of CAD and PCI/CABG (p<0.0001.The overall incidence of CAD in patients presenting with AF was relatively high at 34%; the incidence of PCI/CABG was 21%. Based upon increasing CRF in the western world, we recommend a careful investigation respecting the FRS to either definitely exclude or establish an early diagnosis of CAD--which could contribute to an early and safe therapeutic strategy considering type Ic antiarrhythmics and oral anticoagulation.

    Epidemiologic evidence for work stress as a risk factor for coronary heart disease is mostly based on a single measure of stressful work known as job strain, a combination of high demands and low job control. We examined whether a complementary stress measure that assesses an imbalance between efforts spent at work and rewards received predicted coronary heart disease. This multicohort study (the "IPD-Work" consortium) was based on harmonized individual-level data from 11 European prospective cohort studies. Stressful work in 90,164 men and women without coronary heart disease at baseline was assessed by validated effort-reward imbalance and job strain questionnaires. We defined incident coronary heart disease as the first nonfatal myocardial infarction or coronary death. Study-specific estimates were pooled by random effects meta-analysis. At baseline, 31.7% of study members reported effort-reward imbalance at work and 15.9% reported job strain. During a mean follow-up of 9.8 years, 1,078 coronary events were recorded. After adjustment for potential confounders, a hazard ratio of 1.16 (95% confidence interval, 1.00-1.35) was observed for effort-reward imbalance compared with no imbalance. The hazard ratio was 1.16 (1.01-1.34) for having either effort-reward imbalance or job strain and 1.41 (1.12-1.76) for having both these stressors compared to having neither effort-reward imbalance nor job strain. Individuals with effort-reward imbalance at work have an increased risk of coronary heart disease, and this appears to be independent of job strain experienced. These findings support expanding focus beyond just job strain in future research on work stress.

    Full Text Available Aims. To investigate the treatment of hospitalized patients with coronary artery disease (CAD and the prognostic factors in Beijing, China. Materials and Methods. A multicenter prospective study was conducted through an integrative platform of clinical and research at 12 hospitals in Beijing, China. The clinical information of 3537 hospitalized patients with CAD was collected from September 2009 to May 2011, and the efficacy of secondary prevention during one-year followup was evaluated. In addition, a logistic regression analysis was performed to identify some factors which will have independent impact on the prognosis. Results. The average age of all patients was 64.88 ± 11.97. Of them, 65.42% are males. The medicines for patients were as follows: antiplatelet drugs accounting for 91.97%, statins accounting for 83.66%, β-receptor blockers accounting for 72.55%, ACEI/ARB accounting for 58.92%, and revascularization (including PCI and CABG accounting for 40.29%. The overall incidence of cardiovascular events was 13.26% (469/3537. The logistic stepwise regression analysis showed that heart failure (OR, 3.707, 95% CI = 2.756–4.986, age ≥ 65 years old (OR, 2.007, 95% CI = 1.587–2.53, and myocardial infarction (OR, 1.649, 95% CI = 1.322–2.057 were the independent risk factors of others factors for cardiovascular events that occurred during followup of one-year period. Integrative medicine (IM therapy showed the beneficial tendency for decreasing incidence of cardiovascular events, although no statistical significance was found (OR, 0.797, 95% CI = 0.613~1.036.

    The long-term outcomes of radiofrequency catheter ablation (RFCA) in patients with Wolff-Parkinson-White syndrome (WPW) remain unclear. We investigated the impact of RFCA on the long-term risk of coronary events and mortality in WPW patients. We conducted a prospective cohort study utilizing the Taiwan National Health Insurance Research Database. Between 2000 and 2003, WPW patients with no prior coronary artery disease (CAD) history, aged over 18 years, who underwent RFCA were identified. WPW patients without RFCA were matched with propensity-score 1:4 matching for confounding coronary risk factors. The study outcomes were total mortality and coronary events. A total of 1524 matched non-ablated WPW patients (Group 1) and 381 ablated WPW patients (Group 2) were included. After a mean follow-up of 9.6 ± 2.9 and 10.3 ± 1.9 years, respectively, ablation group demonstrated a lower incidence of mortality compared with non-ablation group (17 vs. 26/1000 person-years, P < 0.001; adjusted HR: 0.57, 95% CI: 0.44-0.7). However, ablation group had a higher incidence of coronary events compared with non-ablation group (47 vs. 82/1000 person-years, P < 0.001; adjusted HR: 1.69, 95% CI: 1.4-2.04). The ablation-treated WPW patients had lower risk of total mortality but higher risk of coronary events than non-ablated WPW patients during the long-term follow-up. Coronary artery injury produced by RFCA may account for the increased risk of coronary events. Therefore, the ablation strategies to avoid coronary artery injury should be implemented.

    2008-01-01

    The reported low mortality rate from coronary heart disease in Portugal, Spain, Italy, Greece, and France, to a lesser extent, has been attributed in numerous nutritional studies to the consumption of a Mediterranean-type diet. There are still many unresolved issues about the direct causal effect of the Mediterranean dietary regime on low incidence of coronary heart disease. An analysis of coronary heart disease mortality rates in Europe from a latitudinal gradient perspective has shown to have a close correlation to incident solar radiation. It is surmised that the resulting increased in situ biosynthesis of Vitamin D 3 could be the critical missing confounder in the analysis of the beneficial health outcome of the Mediterranean diet

    Coronary heart disease is a major cause of heart failure. Availability of risk-prediction models that include both clinical parameters and biomarkers is limited. We aimed to develop such a model for prediction of incident heart failure. A multivariable risk-factor model was developed for prediction of first occurrence of heart failure death or hospitalization. A simplified risk score was derived that enabled subjects to be grouped into categories of 5-year risk varying from 20%. Among 7101 patients from the LIPID study (84% male), with median age 61years (interquartile range 55-67years), 558 (8%) died or were hospitalized because of heart failure. Older age, history of claudication or diabetes mellitus, body mass index>30kg/m 2 , LDL-cholesterol >2.5mmol/L, heart rate>70 beats/min, white blood cell count, and the nature of the qualifying acute coronary syndrome (myocardial infarction or unstable angina) were associated with an increase in heart failure events. Coronary revascularization was associated with a lower event rate. Incident heart failure increased with higher concentrations of B-type natriuretic peptide >50ng/L, cystatin C>0.93nmol/L, D-dimer >273nmol/L, high-sensitivity C-reactive protein >4.8nmol/L, and sensitive troponin I>0.018μg/L. Addition of biomarkers to the clinical risk model improved the model's C statistic from 0.73 to 0.77. The net reclassification improvement incorporating biomarkers into the clinical model using categories of 5-year risk was 23%. Adding a multibiomarker panel to conventional parameters markedly improved discrimination and risk classification for future heart failure events. Copyright © 2017 Elsevier Ireland Ltd.

    Paraoxonase 1 (PON1) plays a major role in the oxidation of low density lipoprotein and in the prevention of coronary atherogenesis. In this context, coding region polymorphisms of PON1 gene, responsible for the enzyme activity, has become of interest as a marker for atherogenesis. A study and follow-up was conducted on 529 patients with an acute coronary event in order to assess the association between the PON1 Q192R (rs662;A/G) polymorphism, the type of acute coronary syndrome, cardiovascular risk factors (arterial hypertension, diabetes mellitus, dyslipidaemia, and smoking), the extent and severity of coronary atherosclerosis, and the medium-term clinical follow-up. The QQ genotype was found in 245 (46.3%) patients, with 218 (41.2%) patients showing the QR genotype, and 66 (14.5%) patients had the RR genotype. No significant differences were found between the QQ and QR/RR genotypes as regards the clinical characteristics, the analytical data, and the angiographic variables. Similarly, Kaplan-Meier survival analysis showed no significant differences in presenting with a new acute coronary event (p=0.598), cardiac mortality (p=0.701), stent thrombosis (p=0.508), or stent re-stenosis (p=0.598) between QQ and QR/RR genotypes during the follow-up period (3.3±2.2 years). In patients with an acute coronary syndrome, the PON1 Q192R genotypes did not influence the risk of suffering a new acute coronary event during the medium-term follow-up.

    Full Text Available Introduction: An excess in cardiovascular (CV morbidity and mortality has been recognized in Rheumatoid Arthritis (RA patients when compared to the general population. Given the paucity of prospective data, our aim was to estimate the incidence of CV events and the contribution of traditional CVD risk factors and RA-related parameters to future events. Methods: Incident fatal and non-fatal CV events (hospitalizations due to unstable angina, myocardial infarction, coronary artery revascularization procedures, stroke, or CV death were assessed in a prospective cohort of RA women followed since 2007 and without CV events at cohort entry. The presence of traditional CV risk factors, disease characteristics, medication, carotid ultrasound, and biomarkers of inflammation and endothelial activation were evaluated at baseline. Univariate Cox proportional hazard models were used to identify risk factors for CV events. Results: Among 106 women followed over 565 patient-years we identified 4 CV events (1 fatal stroke, 2 myocardial infarction and 1 unstable angina, which contributed to an incidence rate of 7 per 1000 person-years (95%CI 2.0- 13.9. Patients who developed CV events were older, but the distribution of other traditional CV risk factors was otherwise similar in both groups. Also, corticosteroid dosage and proportion of patients with carotid atherosclerotic plaques was higher in those with CV events. Erythrocyte sedimentation rate (ESR (HR 1.036; 95%CI 1.005-1.067 and soluble intercellular adhesion molecule-1 (sICAM-1 serum levels (HR 1.002; 95%CI 1.000-1.003 significantly contributed to CV events. These results remained significant after adjusting for patients’ age. Conclusion: We found an incidence of cardiovascular events in women with RA of 7 per 1000 patent-years. This value is similar to that found in other Portuguese cohort of RA patients1 and much higher than the incidence reported for the general Portuguese population. Markers of

    Chemical, biological, radiological and nuclear (CBRN) incidents, both caused accidentally by human error or natural/technological events and determined intentionally as criminal/malicious/terroristic acts, have consequences that could be differently characterized. In the last years many efforts to analyze the economic impact of terrorist threat have been carried out, while researches specifically concerning CBRN events have not been extensively undertaken. This paper in particular aims at proposing a methodological approach for studying macro-level economic impact profiles of biological incidents caused by weaponized and non-weaponized materials. The suggested approach investigates the economic consequences of biological incidents according to two main dimensions: type of large-scale effect and persistence of effect. Biological incident economic impacts are analyzed taking into account the persistence of effect during time as short-term impact (i.e. immediately after the incident), medium-term impact (i.e. by a month) and long-term impact (i.e. by years). The costs due to preventive countermeasure against biological threats (e.g. prevention, protection and preparedness expenses) are not taken into account. To this purpose, information on the key features of past biological incidents can be used as case studies to try to build impact profiles taking into account the proposed two main dimensions. Consequence management and effect mitigation of CBRN emergencies and disasters may benefit from an ex ante definition of the impact profiling related to this kind of incidents. The final goal of this paper is to define an approach to organize information on possible biological events according to their impact profile for supporting more effective and efficient first responders' prompt actions and policy makers' strategic decisions after the event occurrence.

    Cardiovascular disease (CVD) is the leading cause of death in rheumatoid arthritis (RA) patients. This study is the first to report the association of hydroxychloroquine (an antirheumatic medication that has been associated with decreased risk of diabetes, a less atherogenic lipid profile, and antithrombotic properties) with CVD in RA. A retrospective incident RA cohort from January 1, 2001, to October 31, 2013, excluding patients with CVD prior to RA diagnosis, was constructed. Patients were categorized as hydroxychloroquine users versus nonusers and were allowed to contribute time to either group according to hydroxychloroquine exposure. The primary outcome was adjudicated incident CVD defined as a composite of coronary artery disease, stroke, transient ischemic attack, sudden cardiac death, and peripheral artery disease with arterial revascularization procedure. The secondary outcome was a composite of incident coronary artery disease, stroke, and transient ischemic attack. Cox time-varying regression models were used to estimate the association between hydroxychloroquine exposure and development of CVD, after adjusting for propensity score and relevant confounders, including demographics, CVD-related comorbidities, RA severity, and activity indicators and medications. We included 1266 RA patients, 547 hydroxychloroquine users, and 719 nonusers. During the observation period, 102 CVD events occurred, 3 in hydroxychloroquine users and 99 in nonusers. The fully adjusted Cox model showed a hazard ratio of 0.28 (95% CI 0.12-0.63, P=0.002) for incident CVD and 0.30 (95% CI 0.13-0.68, P=0.004) for incident composite coronary artery disease, stroke, and transient ischemic attack for hydroxychloroquine users versus nonusers, respectively. In this hypothesis-generating study, hydroxychloroquine use was associated with a 72% decrease in the risk of incident CVD in RA patients. If these preliminary results are confirmed in larger studies, our findings may be used as a

    Cerebrovascular accident (CVA) and transient ischemic attack (TIA) related to percutaneous coronary intervention (PCI) are relatively rare complications, but they are associated with high morbidity and mortality. Given the evolution of both CVA risk and PCI techniques over time, this study was conducted to evaluate trends in CVA and TIA associated with PCI and to identify variables associated with neurologic events. Consecutive patients undergoing PCI at the Washington Hospital Center between January 2002 and June 2015 were included. Prespecified data were prospectively collected, including baseline and procedural characteristics, in-hospital outcomes, and 1-year mortality. The subjects who had a CVA or TIA during or immediately after PCI were compared with those without procedure-associated CVA or TIA. Overall, 25,626 patients were included in the study. The mean age was 65.0 ± 12.4 years, 16,949 (65.2%) were male, and 7,436 (28.6%) were African American. From 2002 to 2015, 110 neurologic events post-PCI were diagnosed (0.43%); this included 86 CVAs (0.34%) and 24 TIAs (0.09%). The annual rate of postprocedural neurologic events was 0.42% ± 0.12%. There were significant changes in baseline risk factors over time, with increasing age, incidence of insulin-dependent diabetes, and chronic kidney disease. Patients with neurologic events were more often African American (43.6% vs 28.6%, P < .001) with prior history of CVA (24.5% vs 7.8%, P < .001), chronic renal insufficiency (26.6% vs 15.2%, P < .001), and insulin-dependent diabetes (19.1% vs 12.4%, P = .03). Acute myocardial infarction (56% vs 30.4%, P < .001) and cardiogenic shock (20.2% vs 3%, P < .001) were also more common among patients with neurologic events post-PCI. After multivariable adjustment, use of an intraaortic balloon pump was strongly associated with neurologic events (odds ratio [OR] 4.9, 95% CI 2.7-8.8, P < .001), as was prior CVA (OR 2.4, 95% CI 1.4-4.4, P = .002) and African American race (OR

    Background The incremental prognostic value of assessing the metabolic syndrome has been disputed. Little is known regarding its prognostic value in patients after an acute coronary syndrome. Design and methods The presence of metabolic syndrome (2005 International Diabetes Federation) was assessed at baseline in SOLID-TIMI 52, a trial of patients within 30 days of acute coronary syndrome (median follow-up 2.5 years). The primary endpoint was major coronary events (coronary heart disease death, myocardial infarction or urgent coronary revascularization). Results At baseline, 61.6% ( n = 7537) of patients met the definition of metabolic syndrome, 34.7% (n = 4247) had diabetes and 29.3% had both ( n = 3584). The presence of metabolic syndrome was associated with increased risk of major coronary events (adjusted hazard ratio (adjHR) 1.29, p metabolic syndrome was numerically but not significantly associated with the risk of major coronary events (adjHR 1.13, p = 0.06). Conversely, diabetes was a strong independent predictor of major coronary events in the absence of metabolic syndrome (adjHR 1.57, p metabolic syndrome identified patients at highest risk of adverse outcomes but the incremental value of metabolic syndrome was not significant relative to diabetes alone (adjHR 1.07, p = 0.54). Conclusions After acute coronary syndrome, diabetes is a strong and independent predictor of adverse outcomes. Assessment of the metabolic syndrome provides only marginal incremental value once the presence or absence of diabetes is established.

    Full Text Available The chemokine RANTES (regulated on activation, normal T-cell expressed and secreted/CCL5 is involved in the pathogenesis of cardiovascular disease in mice, whereas less is known in humans. We hypothesised that its relevance for atherosclerosis should be reflected by associations between CCL5 gene variants, RANTES serum concentrations and protein levels in atherosclerotic plaques and risk for coronary events.We conducted a case-cohort study within the population-based MONICA/KORA Augsburg studies. Baseline RANTES serum levels were measured in 363 individuals with incident coronary events and 1,908 non-cases (mean follow-up: 10.2±4.8 years. Cox proportional hazard models adjusting for age, sex, body mass index, metabolic factors and lifestyle factors revealed no significant association between RANTES and incident coronary events (HR [95% CI] for increasing RANTES tertiles 1.0, 1.03 [0.75-1.42] and 1.11 [0.81-1.54]. None of six CCL5 single nucleotide polymorphisms and no common haplotype showed significant associations with coronary events. Also in the CARDIoGRAM study (>22,000 cases, >60,000 controls, none of these CCL5 SNPs was significantly associated with coronary artery disease. In the prospective Athero-Express biobank study, RANTES plaque levels were measured in 606 atherosclerotic lesions from patients who underwent carotid endarterectomy. RANTES content in atherosclerotic plaques was positively associated with macrophage infiltration and inversely associated with plaque calcification. However, there was no significant association between RANTES content in plaques and risk for coronary events (mean follow-up 2.8±0.8 years.High RANTES plaque levels were associated with an unstable plaque phenotype. However, the absence of associations between (i RANTES serum levels, (ii CCL5 genotypes and (iii RANTES content in carotid plaques and either coronary artery disease or incident coronary events in our cohorts suggests that RANTES may not be a

    Previous studies have suggested that a high intake of sugar-sweetened beverages is positively associated with the risk of a coronary event. However, a few studies have examined the association between sucrose (the most common extrinsic sugar in Sweden) and incident coronary events. The objective of the present study was to examine the associations between sucrose intake and coronary event risk and to determine whether these associations are specific to certain subgroups of the population (i.e. according to physical activity, obesity status, educational level, alcohol consumption, smoking habits, intake of fat and intake of fruits and vegetables). We performed a prospective analysis on 26 190 individuals (62 % women) free from diabetes and without a history of CVD from the Swedish population-based Malmö Diet and Cancer cohort. Over an average of 17 years of follow-up (457 131 person-years), 2493 incident cases of coronary events were identified. Sucrose intake was obtained from an interview-based diet history method, including 7-d records of prepared meals and cold beverages and a 168-item diet questionnaire covering other foods. Participants who consumed >15 % of their energy intake (E%) from sucrose showed a 37 (95 % CI 13, 66) % increased risk of a coronary event compared with the lowest sucrose consumers (<5 E%) after adjusting for potential confounders. The association was not modified by the selected lifestyle factors. The results indicated that sucrose consumption higher than 15 E% (5 % of this population) is associated with an increased risk of a coronary event.

    Genetic variants have been associated with the risk of coronary heart disease. In this study, we tested whether or not a composite of these variants could ascertain the risk of both incident and recurrent coronary heart disease events and identify those individuals who derive greater clinical benefit from statin therapy. A community-based cohort study (the Malmo Diet and Cancer Study) and four randomised controlled trials of both primary prevention (JUPITER and ASCOT) and secondary prevention (CARE and PROVE IT-TIMI 22) with statin therapy, comprising a total of 48,421 individuals and 3477 events, were included in these analyses. We studied the association of a genetic risk score based on 27 genetic variants with incident or recurrent coronary heart disease, adjusting for traditional clinical risk factors. We then investigated the relative and absolute risk reductions in coronary heart disease events with statin therapy stratified by genetic risk. We combined data from the different studies using a meta-analysis. When individuals were divided into low (quintile 1), intermediate (quintiles 2-4), and high (quintile 5) genetic risk categories, a significant gradient in risk for incident or recurrent coronary heart disease was shown. Compared with the low genetic risk category, the multivariable-adjusted hazard ratio for coronary heart disease for the intermediate genetic risk category was 1·34 (95% CI 1·22-1·47, pgenetic risk category was 1·72 (1·55-1·92, pgenetic risk categories. Similarly, we noted greater absolute risk reductions in those individuals in higher genetic risk categories (p=0·0101), resulting in a roughly threefold decrease in the number needed to treat to prevent one coronary heart disease event in the primary prevention trials. Specifically, in the primary prevention trials, the number needed to treat to prevent one such event in 10 years was 66 in people at low genetic risk, 42 in those at intermediate genetic risk, and 25 in those at high

    Full Text Available Analyses of circulating metabolites in large prospective epidemiological studies could lead to improved prediction and better biological understanding of coronary heart disease (CHD. We performed a mass spectrometry-based non-targeted metabolomics study for association with incident CHD events in 1,028 individuals (131 events; 10 y. median follow-up with validation in 1,670 individuals (282 events; 3.9 y. median follow-up. Four metabolites were replicated and independent of main cardiovascular risk factors [lysophosphatidylcholine 18∶1 (hazard ratio [HR] per standard deviation [SD] increment = 0.77, P-value<0.001, lysophosphatidylcholine 18∶2 (HR = 0.81, P-value<0.001, monoglyceride 18∶2 (MG 18∶2; HR = 1.18, P-value = 0.011 and sphingomyelin 28∶1 (HR = 0.85, P-value = 0.015]. Together they contributed to moderate improvements in discrimination and re-classification in addition to traditional risk factors (C-statistic: 0.76 vs. 0.75; NRI: 9.2%. MG 18∶2 was associated with CHD independently of triglycerides. Lysophosphatidylcholines were negatively associated with body mass index, C-reactive protein and with less evidence of subclinical cardiovascular disease in additional 970 participants; a reverse pattern was observed for MG 18∶2. MG 18∶2 showed an enrichment (P-value = 0.002 of significant associations with CHD-associated SNPs (P-value = 1.2×10-7 for association with rs964184 in the ZNF259/APOA5 region and a weak, but positive causal effect (odds ratio = 1.05 per SD increment in MG 18∶2, P-value = 0.05 on CHD, as suggested by Mendelian randomization analysis. In conclusion, we identified four lipid-related metabolites with evidence for clinical utility, as well as a causal role in CHD development.

    Coronary angiography (CAG) is an invasive diagnostic procedure, which could lead to procedure related complications. One of the well known post-procedural complications is cerebral embolic infarction with or without symptoms. Silent embolic cerebral infarction (SECI) has clinical significance because it can progress to a decline in cognitive function and increase the risk of dementia in the long term. The aim of this study was to detect the incidence and predictors of SECI after diagnostic CAG using diffusion-weighted magnetic resonance imaging (DW-MRI). A total of 197 patients with coronary artery disease who underwent DW-MRI for evaluation of intracranial vasculopathy before coronary artery bypass graft surgery were retrospectively enrolled in the present study. DW-MRI was performed within 48 h after diagnostic CAG. SECI was diagnosed as presence of focal bright high signal intensity in DW-MRI. Patients were divided into groups according to presence/absence of SECI (+ SECI vs. - SECI, respectively). The clinical and angiographic characteristics were analyzed and independent predictors were evaluated. Of the 197 patients, SECI occurred in 20 patients (10.2%) after diagnostic CAG. Age, female gender, frequency of underlying atrial fibrillation, extent of coronary disease, and fluoroscopic time during diagnostic CAG were not different between the + SECI and - SECI groups. Left ventricular ejection fraction was significantly lower in the + SECI group than in the - SECI group (45.9 ± 8.5% vs. 51.4 ± 13.1%, p=0.014) and performance rate of internal mammary artery (IMA) angiography was significantly higher in the + SECI group compared with the - SECI group (85% vs. 37.2%, pSECI (OR=14.642; 95% CI=3.201 to 66.980, p=0.001). The incidence of SECI after diagnostic CAG was not infrequent. Diagnostic CAG with IMA angiography may increase the risk of SECI. Copyright © 2009 Elsevier Ireland Ltd. All rights reserved.

    Aims To study the effects of smoking restrictions in Germany on coronary syndromes and their associated costs. Methods and results All German states implemented laws partially restricting smoking in the public and hospitality sectors between August 2007 and July 2008. We conducted a before-and-after study to examine trends for the hospitalization rate for angina pectoris and acute myocardial infarction (AMI) for an insurance cohort of 3,700,384 individuals 30 years and older. Outcome measures were hospitalization rates for coronary syndromes, and hospitalization costs. Mean age of the cohort was 56 years, and two-thirds were female. Some 2.2 and 1.1% persons were hospitalized for angina pectoris and AMI, respectively, during the study period from January 2004 through December 2008. Law implementation was associated with a 13.3% (95% confidence interval 8.2, 18.4) decline in angina pectoris and an 8.6% (5.0, 12.2) decline in AMI after 1 year. Hospitalization costs also decreased significantly for the two conditions—9.6% (2.5, 16.6) for angina pectoris and 20.1% (16.0, 24.2) for AMI at 1 year following law implementation. Assuming the law caused the observed declines, it prevented 1,880 hospitalizations and saved 7.7 million Euros in costs for this cohort during the year following law implementation. Conclusions Partial smoking restrictions in Germany were followed by reductions in hospitalization for angina pectoris and AMI, declines that continued through 1 year following these laws and resulted in substantial cost savings. Strengthening the laws could further reduce morbidity and costs from acute coronary syndromes in Germany. PMID:22350716

    Full Text Available Previous studies in mice and humans have implicated the lipoprotein receptor SCARB1 in association with atherosclerosis and lipid levels. In the current study, we sought to examine association of SCARB1 missense single nucleotide polymorphism (SNP rs4238001 with incident coronary heart disease (CHD.Genotypes for rs4238001 were imputed for 2,319 White, 1,570 African American, and 1,292 Hispanic-American MESA participants using the 1,000 Genomes reference set. Cox proportional hazards models were used to determine association of rs4238001 with incident CHD, with adjustments for age, sex, study site, principal components of ancestry, body mass index, diabetes status, serum creatinine, lipid levels, hypertension status, education and smoking exposure. Meta-analysis across race/ethnic groups within MESA showed statistically significant association of the T allele with higher risk of CHD under a consistent and formally adjudicated definition of CHD events in this contemporary cohort study (hazard ratio [HR] = 1.49, 95% CI [1.04, 2.14], P = 0.028. Analyses combining MESA with additional population-based cohorts expanded our samples in Whites (total n = 11,957 with 871 CHD events and African Americans (total n = 5,962 with 355 CHD events and confirmed an increased risk of CHD overall (HR of 1.19 with 95% CI [1.04, 1.37], P = 0.013, in African Americans (HR of 1.49 with 95% CI [1.07, 2.06], P = 0.019, in males (HR of 1.29 with 95% CI [1.08, 1.54], P = 4.91 x 10(-3 and in White males (HR of 1.24 with 95% CI [1.03, 1.51], P = 0.026.SCARB1 missense rs4238001 is statistically significantly associated with incident CHD across a large population of multiple race/ethnic groups.

    Cell adhesion molecules are key regulators of atherosclerotic plaque development, but circulating levels of soluble fragments, such as intercellular adhesion molecule (sICAM-1) and vascular cell adhesion molecule (sVCAM-1), have yielded conflicting associations with atherosclerotic cardiovascular disease (ASCVD). Endothelial cell-selective adhesion molecule (ESAM) is expressed exclusively in platelets and endothelial cells, and soluble ESAM (sESAM) levels have been associated with prevalent subclinical atherosclerosis. We therefore hypothesized that sESAM would be associated with incident ASCVD. sESAM, sICAM-1, and sVCAM-1 were measured in 2,442 participants without CVD in the Dallas Heart Study, a probability-based population sample aged 30-65 years enrolled between 2000 and 2002. ASCVD was defined as first myocardial infarction, stroke, coronary revascularization, or CV death. A total of 162 ASCVD events were analyzed over 10.4 years. Increasing sESAM was associated with ASCVD, independent of risk factors (HR Q4 vs Q1: 2.7, 95% CI 1.6-4.6). Serial adjustment for renal function, sICAM-1, VCAM-1, and prevalent coronary calcium did not attenuate these associations. Continuous ESAM demonstrated similar findings (HR 1.31, 95% CI 1.2-1.4). Addition of sESAM to traditional risk factors improved discrimination and reclassification (delta c-index: P = .009; integrated-discrimination-improvement index P = .001; net reclassification index = 0.42, 95% CI 0.15-0.68). Neither sICAM-1 nor sVCAM-1 was independently associated with ASCVD. sESAM but not sICAM-1 or sVCAM-1 levels are associated with incident ASCVD. Further studies are warranted to investigate the role of sESAM in ASCVD. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Contrast induced nephropathy (CIN is one of important complication of contrast media administration. Its incidence and risk factors among Indonesian patients undergoing coronary intervention has not been reported yet. CIN was defined as increasing of serum creatinine by 0.5 mg/dl or more in the third day following contrast media exposure. Of 312 patients undergoing coronary intervention, 25% developed CIN. Patient-related risk factors comprised of hypertension, diabetes mellitus, NYHA class, proteinuria, serum creatinine > 1.5 mg/dl and ejection fraction ≤ 35%. Contrast-related risk factors comprised of contrast media volume > 300 ml, contrast media type. However, our final model demonstrated that only hypertension [Hazard ratio (HR = 2.89, 95% confidence intrval (CI = 1.78 to 4.71, P = 0.000], diabetes mellitus (HR = 3.09, 95% CI = 1.89 to 5.06, P = 0.000, ejection fraction (EF ≤ 35% (HR = 2.92; 95% CI = 1.72 to 4.96; P = 0.000, total contrast volume > 300 ml (HR = 7.73; 95% CI = 3.09 to 19.37; P = 0.000 and proteinuria (HR = 14.96; 95% CI = 3.45 to 64.86; P = 0.000 were independent risk factors of CIN. In conclusion, CIN developed in 25% of patients undergoing coronary intervention. The independent risk factors of CIN included hypertension, diabetes mellitus, EF ≤ 35%, contrast volume > 300 ml and proteinuria.

    Full Text Available Inflammation is an important factor in the pathogenesis of atherosclerosis, and several markers of inflammation have been associated with an increased risk of cardiovascular events. Physical activity may lower the risk of coronary heart disease(CHD by mitigating inflammation. The aim of the study was to investigate the effects of aerobic exercise training on systemic inflammatory response in patients with stabile coronary artery disease participating in a cardiovascular rehabilitation exercise program. Male (n=29 and female (n=23 patients with stable coronary heart disease were recruited for this study. All patients were divided into two groups: group with regular aerobic physical training during cardiovascular rehabilitation program phase II along 3 weeks in rehabilitation center and 3 weeks after that in home of patients and sedentary lifestyle group. There were no significant differences in gender distribution among analyzed groups. Student’s t test showed no significant difference in mean age, waist circumference (OS and waist/hip ratio (WHR. Degree of obesity was measured by BMI, and there was a significant improvement in BMI in patients who underwent the six-week physical training compared to control group (p<0.05.Physical training during 6 weeks did not show any effects on leukocyte count and ICAM-1 levels compared to control group. The exercise training induced reduction in plasma CRP levels by 23.72%, p<0.001, and reduction in plasma VCAM-1 levels by Moderate aerobic exercise training resulted in a significant reduction of inflammatory state by decreasing CRP and VCAM-1 levels without significant body mass and visceral obesity reduction. The obtained results indicate that regular physical activity is clinically attractive in primary and secondary prevention of coronary heart diseases.

    Longstanding uncontrolled atherogenic risk factors may contribute to left atrial (LA) hypertension, LA enlargement (LAE) and coronary vascular dysfunction. Together they may better identify risk of major adverse cardiac events (MACE). The aim of this study was to test the hypothesis that chronic LA hypertension as assessed by LAE modifies the relationship between coronary vascular function and MACE. In 508 unselected subjects with a normal clinical {sup 82}Rb PET/CT, ejection fraction ≥40 %, no prior coronary artery disease, valve disease or atrial fibrillation, LAE was determined based on LA volumes estimated from the hybrid perfusion and CT transmission scan images and indexed to body surface area. Absolute myocardial blood flow and global coronary flow reserve (CFR) were calculated. Subjects were systematically followed-up for the primary end-point - MACE - a composite of all-cause death, myocardial infarction, hospitalization for heart failure, stroke, coronary artery disease progression or revascularization. During a median follow-up of 862 days, 65 of the subjects experienced a composite event. Compared with subjects with normal LA size, subjects with LAE showed significantly lower CFR (2.25 ± 0.83 vs. 1.95 ± 0.80, p = 0.01). LAE independently and incrementally predicted MACE even after accounting for clinical risk factors, medication use, stress left ventricular ejection fraction, stress left ventricular end-diastolic volume index and CFR (chi-squared statistic increased from 30.9 to 48.3; p = 0.001). Among subjects with normal CFR, those with LAE had significantly worse event-free survival (risk adjusted HR 5.4, 95 % CI 2.3 - 12.8, p < 0.0001). LAE and reduced CFR are related but distinct cardiovascular adaptations to atherogenic risk factors. LAE is a risk marker for MACE independent of clinical factors and left ventricular volumes; individuals with LAE may be at risk of MACE despite normal coronary vascular function. (orig.)

    The high prevalence of cardiovascular risk factors among the renal transplant population accounts for increased mortality. The aim of this study is to determine the incidence of cardiovascular events and factors associated with cardiovascular events in these patients. An observational ambispective follow-up study of renal transplant recipients (n = 2029) in the health district of A Coruña (Spain) during the period 1981-2011 was completed. Competing risk survival analysis methods were applied to estimate the cumulative incidence of developing cardiovascular events over time and to identify which characteristics were associated with the risk of these events. Post-transplant cardiovascular events are defined as the presence of myocardial infarction, invasive coronary artery therapy, cerebral vascular events, new-onset angina, congestive heart failure, rhythm disturbances, peripheral vascular disease and cardiovascular disease and death. The cause of death was identified through the medical history and death certificate using ICD9 (390-459, except: 427.5, 435, 446, 459.0). The mean age of patients at the time of transplantation was 47.0 ± 14.2 years; 62% were male. 16.5% had suffered some cardiovascular disease prior to transplantation and 9.7% had suffered a cardiovascular event. The mean follow-up period for the patients with cardiovascular event was 3.5 ± 4.3 years. Applying competing risk methodology, it was observed that the accumulated incidence of the event was 5.0% one year after transplantation, 8.1% after five years, and 11.9% after ten years. After applying multivariate models, the variables with an independent effect for predicting cardiovascular events are: male sex, age of recipient, previous cardiovascular disorders, pre-transplant smoking and post-transplant diabetes. This study makes it possible to determine in kidney transplant patients, taking into account competitive events, the incidence of post-transplant cardiovascular events and

    Full Text Available BACKGROUND: This study compares inflammation-related biomarkers with established cardiometabolic risk factors in the prediction of incident type 2 diabetes and incident coronary events in a prospective case-cohort study within the population-based MONICA/KORA Augsburg cohort. METHODS AND FINDINGS: Analyses for type 2 diabetes are based on 436 individuals with and 1410 individuals without incident diabetes. Analyses for coronary events are based on 314 individuals with and 1659 individuals without incident coronary events. Mean follow-up times were almost 11 years. Areas under the receiver-operating characteristic curve (AUC, changes in Akaike's information criterion (ΔAIC, integrated discrimination improvement (IDI and net reclassification index (NRI were calculated for different models. A basic model consisting of age, sex and survey predicted type 2 diabetes with an AUC of 0.690. Addition of 13 inflammation-related biomarkers (CRP, IL-6, IL-18, MIF, MCP-1/CCL2, IL-8/CXCL8, IP-10/CXCL10, adiponectin, leptin, RANTES/CCL5, TGF-β1, sE-selectin, sICAM-1; all measured in nonfasting serum increased the AUC to 0.801, whereas addition of cardiometabolic risk factors (BMI, systolic blood pressure, ratio total/HDL-cholesterol, smoking, alcohol, physical activity, parental diabetes increased the AUC to 0.803 (ΔAUC [95% CI] 0.111 [0.092-0.149] and 0.113 [0.093-0.149], respectively, compared to the basic model. The combination of all inflammation-related biomarkers and cardiometabolic risk factors yielded a further increase in AUC to 0.847 (ΔAUC [95% CI] 0.044 [0.028-0.066] compared to the cardiometabolic risk model. Corresponding AUCs for incident coronary events were 0.807, 0.825 (ΔAUC [95% CI] 0.018 [0.013-0.038] compared to the basic model, 0.845 (ΔAUC [95% CI] 0.038 [0.028-0.059] compared to the basic model and 0.851 (ΔAUC [95% CI] 0.006 [0.003-0.021] compared to the cardiometabolic risk model, respectively.

    Full Text Available Patients with metabolic syndrome are at high-risk for development of atherosclerosis and cardiovascular events. The objective of this study was to examine the major determinants of coronary disease severity, including those coronary risk factors associated with metabolic syndrome, during the early period after an acute coronary episode. We tested the hypothesis that inflammatory markers, especially highly sensitive C-reactive protein (hsCRP, are related to coronary atherosclerosis, in addition to traditional coronary risk factors. Subjects of both genders aged 30 to 75 years (N = 116 were prospectively included if they had suffered a recent acute coronary syndrome (acute myocardial infarction or unstable angina pectoris requiring hospitalization and if they had metabolic syndrome diagnosed according to the National Cholesterol Education Program/Adult Treatment Panel III. Patients were submitted to a coronary angiography and the burden of atherosclerosis was estimated by the Gensini score. The severity of coronary disease was correlated (Spearman’s or Pearson’s coefficient with gender (r = 0.291, P = 0.008, age (r = 0.218, P = 0.048, hsCRP (r = 0.256, P = 0.020, ApoB/ApoA ratio (r = 0.233, P = 0.041, and carotid intima-media thickness (r = 0.236, P = 0.041. After multiple linear regression, only male gender (P = 0.046 and hsCRP (P = 0.012 remained independently associated with the Gensini score. In this high-risk population, male gender and high levels of hsCRP, two variables that can be easily obtained, were associated with more extensive coronary disease, identifying patients with the highest potential of developing new coronary events.

    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.

    Global Registry of Acute Coronary Events (GRACE) risk score and red blood cell distribution width (RDW) content can both independently predict major adverse cardiac events (MACEs) in patients with acute coronary syndrome (ACS). We investigated the combined predictive value of RDW and GRACE risk score for cardiovascular events in patients with ACS undergoing percutaneous coronary intervention (PCI) for the first time. We enrolled 480 ACS patients. During a median follow-up time of 37.2 months, 70 (14.58%) patients experienced MACEs. Patients were divided into tertiles according to the baseline RDW content (11.30-12.90, 13.00-13.50, 13.60-16.40). GRACE score was positively correlated with RDW content. Multivariate Cox analysis showed that both GRACE score and RDW content were independent predictors of MACEs (hazard ratio 1.039; 95% confidence interval [CI] 1.024-1.055; p risk of MACEs increased with increasing RDW content (p value of combining RDW content and GRACE risk score was significantly improved, also shown by the net reclassification improvement (NRI = 0.352, p value of RDW and GRACE risk score yielded a more accurate predictive value for long-term cardiovascular events in ACS patients who underwent PCI as compared to each measure alone.

    Background Cumulative exposure to lead is associated with cardiovascular outcomes. Polymorphisms in the δ-aminolevulinic acid dehydratase (ALAD), hemochromatosis (HFE), heme oxygenase-1 (HMOX1), vitamin D receptor (VDR), glutathione S-transferase (GST) supergene family (GSTP1, GSTT1, GSTM1), apolipoprotein E (APOE),angiotensin II receptor-1 (AGTR1) and angiotensinogen (AGT) genes, are believed to alter toxicokinetics and/or toxicodynamics of lead. Objectives We assessed possible effect modification by genetic polymorphisms in ALAD, HFE, HMOX1, VDR, GSTP1, GSTT1, GSTM1, APOE, AGTR1 and AGT individually and as the genetic risk score (GRS) on the association between cumulative lead exposure and incident coronary heart disease (CHD) events. Methods We used K-shell-X-ray fluorescence to measure bone lead levels. GRS was calculated on the basis of 22 lead-related loci. We constructed Cox proportional hazard models to compute adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for incident CHD. We applied inverse probability weighting to account for potential selection bias due to recruitment into the bone lead sub-study. Results Significant effect modification was found by VDR, HMOX1, GSTP1, APOE, and AGT genetic polymorphisms when evaluated individually. Further, the bone lead-CHD associations became larger as GRS increases. After adjusting for potential confounders, a HR of CHD was 2.27 (95%CI: 1.50–3.42) with 2-fold increase in patella lead levels, among participants in the top tertile of GRS. We also detected an increasing trend in HRs across tertiles of GRS (p-trend = 0.0063). Conclusions Our findings suggest that lead-related loci as a whole may play an important role in susceptibility to lead-related CHD risk. These findings need to be validated in a separate cohort containing bone lead, lead-related genetic loci and incident CHD data. PMID:27584680

    To compare gender-related lifestyle changes and risk factor management after hospitalisation for a coronary event or revascularisation intervention in Europe. The EUROASPIRE III survey was carried out in 22 European countries in 2006-2007. Consecutive patients having had a coronary event or revascularisation before the age of 80 were identified. A total of 8966 patients (25.3% women) were interviewed and underwent clinical and biochemical tests at least 6 months after hospital admission. Trends in cardiovascular risk management were assessed on the basis of the 1994-1995, 1999-2000 and 2006-2007 EUROASPIRE surveys. Female survey participants were generally older and had a lower educational level than male participants (pevent. This gap did not appear to narrow between 1994 and 2007.

    Approximately 16,000 study subjects in the Adult Health Study sample who had received examination at least once during the 20 years (1958 - 78) in Hiroshima or Nagasaki and were found to have neither stroke nor coronary heart disease (CHD) at the initial examination were studied for the incidence of stroke and CHD and the relationship of these to atomic bomb radiation exposure. Their secular trends were also studied. Findings suggestive of a relationship between stroke and radiation exposure among Hiroshima females were first discovered for the years 1969 - 73, that is, 24 - 28 years after A-bomb exposure. In general, this association is supported by the present analysis. Stroke incidence continued to decrease during the present report's period of observation. Analysis by type showed that cerebral infarction and cerebral hemorrhage both decreased, but the decrease of the latter is especially remarkable. The trend to decrease is observed in both sexes and in both cities. A relationship between CHD and radiation exposure was, as noted for stroke, first observed only in Hiroshima females for the years 1969 - 73, but from this analysis it appears that the trend began earlier and the association is getting stronger with the passage of time. Analysis by type showed myocardial infarction (MI), but not angina pectoris, to be related to radiation exposure. The incidence rate for CHD, especially for MI, was almost constant during the observation period, it being 1.2/1,000 person-years on the average. Comparing by sex, the incidence rate was constant in males. In females, the pattern varied with time. There appear to be no between-city differences in secular trends - essentially constant.

    Arterial hypertension is an established risk factor for acute coronary syndrome (ACS). Multidetector computed tomography (MDCT) is an accurate and less invasive technique for assessment of the degree of coronary artery luminal narrowing and characterization of coronary atherosclerosis. We therefore aimed to investigate the predictive power of MDCT for future ACS events and compared with traditional parameters in patients with hypertension. One hundred and thirty-four patients (93 men, mean age 70±11 years) with hypertension underwent MDCT for evaluation of coronary artery disease. MDCT analysis focused on the presence of plaques, the degree of stenosis, and the plaque characteristics. Traditional parameters included Framingham risk score, carotid intima-media thickness, and left ventricular mass index. During a mean follow-up of 39±10 months, ACS events occurred in 10 patients, including myocardial infarction (n=3) and unstable angina (n=7). Multivariate analysis identified total number of low attenuation plaques as an independent predictor of ACS events (p<0.001). We demonstrated that non-obstructive low attenuation coronary plaques on MDCT predicted more accurately future ACS events in patients with hypertension than traditional parameters. (author)

    Longstanding uncontrolled atherogenic risk factors may contribute to left atrial (LA) hypertension, LA enlargement (LAE) and coronary vascular dysfunction. Together they may better identify risk of major adverse cardiac events (MACE). The aim of this study was to test the hypothesis that chronic LA hypertension as assessed by LAE modifies the relationship between coronary vascular function and MACE. In 508 unselected subjects with a normal clinical (82)Rb PET/CT, ejection fraction ≥40 %, no prior coronary artery disease, valve disease or atrial fibrillation, LAE was determined based on LA volumes estimated from the hybrid perfusion and CT transmission scan images and indexed to body surface area. Absolute myocardial blood flow and global coronary flow reserve (CFR) were calculated. Subjects were systematically followed-up for the primary end-point - MACE - a composite of all-cause death, myocardial infarction, hospitalization for heart failure, stroke, coronary artery disease progression or revascularization. During a median follow-up of 862 days, 65 of the subjects experienced a composite event. Compared with subjects with normal LA size, subjects with LAE showed significantly lower CFR (2.25 ± 0.83 vs. 1.95 ± 0.80, p = 0.01). LAE independently and incrementally predicted MACE even after accounting for clinical risk factors, medication use, stress left ventricular ejection fraction, stress left ventricular end-diastolic volume index and CFR (chi-squared statistic increased from 30.9 to 48.3; p = 0.001). Among subjects with normal CFR, those with LAE had significantly worse event-free survival (risk adjusted HR 5.4, 95 % CI 2.3 - 12.8, p < 0.0001). LAE and reduced CFR are related but distinct cardiovascular adaptations to atherogenic risk factors. LAE is a risk marker for MACE independent of clinical factors and left ventricular volumes; individuals with LAE may be at risk of MACE despite normal coronary vascular function.

    Full Text Available Abstract Background We investigated whether 9p21 polymorphisms are associated with cardiovascular events in a group of 611 patients enrolled in the Medical, Angioplasty or Surgery Study II (MASS II, a randomized trial comparing treatments for patients with coronary artery disease (CAD and preserved left ventricular function. Methods The participants of the MASS II were genotyped for 9p21 polymorphisms (rs10757274, rs2383206, rs10757278 and rs1333049. Survival curves were calculated with the Kaplan–Meier method and compared with the log-rank statistic. We assessed the relationship between baseline variables and the composite end-point of death, death from cardiac causes and myocardial infarction using a Cox proportional hazards survival model. Results We observed significant differences between patients within each polymorphism genotype group for baseline characteristics. The frequency of diabetes was lower in patients carrying GG genotype for rs10757274, rs2383206 and rs10757278 (29.4%, 32.8%, 32.0% compared to patients carrying AA or AG genotypes (49.1% and 39.2%, p = 0.01; 52.4% and 40.1%, p = 0.01; 47.8% and 37.9%, p = 0.04; respectively. Significant differences in genotype frequencies between double and triple vessel disease patients were observed for the rs10757274, rs10757278 and rs1333049. Finally, there was a higher incidence of overall mortality in patients with the GG genotype for rs2383206 compared to patients with AA and AG genotypes (19.5%, 11.9%, 11.0%, respectively; p = 0.04. Moreover, the rs2383206 was still significantly associated with a 1.75-fold increased risk of overall mortality (p = 0.02 even after adjustment of a Cox multivariate model for age, previous myocardial infarction, diabetes, smoking and type of coronary anatomy. Conclusions Our data are in accordance to previous evidence that chromosome 9p21 genetic variation may constitute a genetic modulator in the cardiovascular system in different

    Full Text Available BACKGROUND: Neopterin is a soluble biomarker of monocyte activation and its increased concentration might be expressed in atherosclerosis. Until recently, there has been lacking of information on the prognostic role of neopterin in acute coronary syndromes (ACS. The study was aimed at measuring the associations between elevated serum neopterin and increased risk of cardiovascular (CV events in ACS. METHODS: This was a prospective cohort study, recruited 71 ACS patients from January 31 through August 31, 2007 in Sanglah Hospital of Udayana School of Medicine, Denpasar, Bali. Cardiovascular events, such as: CV death, recurrent myocardial infarction, stroke and recurrent myocardial ischemia were previously defined. Relative risk and survival rate were measured successively by Cox proportional model and Kaplan-Meier curve. RESULTS: Of 71 ACS patients aged 56.8±9.5 years, 21 (29.5% subjects underwent CV events. Overall mean followup was 151.6 (95% CI: 129.7-173.5 days. Baseline characteristic were similarly distributed between groups with the highest quartile neopterin level (≥14.7 nmol/L than those with lowest quartile (≤6.2 nmol/L. Patients with the highest quartile had the worst survival curve than those with the lowest quartile (log-rank test; p=0.047. On Cox proportional model, relative risk of highest quartile group was 5.84 (95% CI: 1.19-28.47; p=0.029 compared to lowest quartile, after being adjusted with other predictors. CONCLUSIONS: Elevated serum neopterin is associated with increased risk of CV events in acute coronary syndromes. KEYWORDS: neopterin, cardiovascular events, acute coronary syndromes.

    Persons of lower socioeconomic status have greater cardiovascular risk than those of higher socioeconomic status. However, the mechanism through which socioeconomic status affects cardiovascular disease (CVD) is uncertain. Virtually no data are available that examine the prospective association between novel inflammatory and hemostatic CVD risk indicators, socioeconomic status, and incident CVD events. We assessed the relationship between 2 indicators of socioeconomic status (education and income), traditional and novel CVD risk factors (high sensitivity C-reactive protein, soluble intercellular adhesion molecule-1, fibrinogen, and homocysteine), and incident CVD events among 22,688 apparently healthy female health professionals participating in the Women's Health Study. These women were followed up for 10 years for the development of myocardial infarction, ischemic stroke, coronary revascularization, and cardiovascular death. More educated women were less likely to be smokers; had a lower prevalence of hypertension, diabetes, and obesity; and were more likely to participate in vigorous physical activity than less educated women. At baseline, median total cholesterol, low-density lipoprotein, triglyceride, C-reactive protein, intercellular adhesion molecule-1, fibrinogen, and homocysteine levels for women in 5 categories of education (master's degree, and a doctoral degree) and 6 categories of income [ or = 100,000 dollars) decreased progressively with increasing education or income levels (all Prisk of incident CVD events decreased with increasing education (1.0, 0.7, 0.5, 0.4, and 0.5; P for trend risk factors on the relationship between education/income and CVD events, the relative hazard of incident CVD associated with a 1-category-higher level of education changed from 0.79 in age- and race-adjusted analysis to 0.89 in fully adjusted analysis. The 11% lower risk per 1 category of education remained significant (P for trend=0.006), suggesting that controlling

    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 1.92 mg/L identified a cohort with a 3-year rate of 18.5%, and C-peptide 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. Copyright © 2015 Elsevier Inc. All rights reserved.

    Silent embolic cerebral infarction (SECI) is a major complication of coronary angiography (CAG) and percutaneous coronary intervention (PCI). Patients with stable coronary artery disease (CAD) who underwent CAG with or without PCI were recruited. Cerebral diffusion-weighted magnetic resonance imaging was performed for SECI within 24 hours. Clinical and angiographic characteristics were compared between patients with and without SECI. Silent embolic cerebral infarction occurred in 12 (12%) of the 101 patients. Age, total cholesterol, SYNTAX score (SS), and coronary artery bypass history were greater in the SECI(+) group (65 ± 10 vs 58 ± 11 years,P= .037; 223 ± 85 vs 173 ± 80 mg/dL,P= .048; 30.1 ± 2 vs 15 ± 3,PSECI was more common in the PCI group (8/24 vs 4/77,P= .01). On subanalysis, the SS was significantly higher in the SECI(+) patients in both the CAG and the PCI groups (29.3 ± 1.9 vs 15 ± 3,PSECI after CAG and PCI increases with the complexity of CAD (represented by the SS). The SS is a predictor of the risk of SECI, a complication that should be considered more often after CAG. © The Author(s) 2015.

    Coronary lipid core plaque may be associated with the incidence of subsequent cardiovascular events. We analyzed outcomes of 239 patients who underwent near-infrared spectroscopy (NIRS) coronary imaging between 2009-2011. Multivariable Cox regression was used to identify variables independently associated with the incidence of major adverse cardiovascular events (MACE; cardiac mortality, acute coronary syndromes (ACS), stroke, and unplanned revascularization) during follow-up. Mean patient age was 64±9years, 99% were men, and 50% were diabetic, presenting with stable coronary artery disease (61%) or an acute coronary syndrome (ACS, 39%). Target vessel pre-stenting median lipid core burden index (LCBI) was 88 [interquartile range, IQR 50-130]. Median LCBI in non-target vessels was 57 [IQR 26-94]. Median follow-up was 5.3years. The 5-year MACE rate was 37.5% (cardiac mortality was 15.0%). On multivariable analysis the following variables were associated with MACE: diabetes mellitus, prior percutaneous coronary intervention performed at index angiography, and non-target vessel LCBI. Non-target vessel LCBI of 77 was determined using receiver-operating characteristic curve analysis to be a threshold for prediction of MACE in our cohort. The adjusted hazard ratio (HR) for non-target vessel LCBI ≥77 was 14.05 (95% confidence interval (CI) 2.47-133.51, p=0.002). The 5-year cumulative incidence of events in the above-threshold group was 58.0% vs. 13.1% in the below-threshold group. During long-term follow-up of patients who underwent NIRS imaging, high LCBI in a non-PCI target vessel was associated with increased incidence of MACE. Published by Elsevier Inc.

    Full Text Available Global Registry of Acute Coronary Events (GRACE risk score and red blood cell distribution width (RDW content can both independently predict major adverse cardiac events (MACEs in patients with acute coronary syndrome (ACS. We investigated the combined predictive value of RDW and GRACE risk score for cardiovascular events in patients with ACS undergoing percutaneous coronary intervention (PCI for the first time. We enrolled 480 ACS patients. During a median follow-up time of 37.2 months, 70 (14.58% patients experienced MACEs. Patients were divided into tertiles according to the baseline RDW content (11.30-12.90, 13.00-13.50, 13.60-16.40. GRACE score was positively correlated with RDW content. Multivariate Cox analysis showed that both GRACE score and RDW content were independent predictors of MACEs (hazard ratio 1.039; 95% confidence interval [CI] 1.024-1.055; p < 0.001; 1.699; 1.294-2.232; p < 0.001; respectively. Furthermore, Kaplan-Meier analysis demonstrated that the risk of MACEs increased with increasing RDW content (p < 0.001. For GRACE score alone, the area under the receiver operating characteristic (ROC curve for MACEs was 0.749 (95% CI: 0.707-0.787. The area under the ROC curve for MACEs increased to 0.805 (0.766-0.839, p = 0.034 after adding RDW content. The incremental predictive value of combining RDW content and GRACE risk score was significantly improved, also shown by the net reclassification improvement (NRI = 0.352, p < 0.001 and integrated discrimination improvement (IDI = 0.023, p = 0.002. Combining the predictive value of RDW and GRACE risk score yielded a more accurate predictive value for long-term cardiovascular events in ACS patients who underwent PCI as compared to each measure alone.

    Background: Only few data are available regarding the prognostic impact of myocardial perfusion scintigraphy with 99mTc-sestamibi (MPS) regarding emerging cardiac events in elderly patients Purpose: To evaluate the prognostic value of MPS regarding emerging cardiac events in patients aged =70 years with known or suspected coronary artery disease (CAD). Material and Methods: One hundred and thirty-three patients (74.6 +- 3.7 years) who underwent exercise or pharmacological stress/rest MPS were included in this analysis. Semi-quantitative visual interpretation of MPS images was performed and Summed-Stress- (SSS), Summed-Difference- (SDS), and Summed-Rest Scores (SRS) were calculated. Multivariate logistic regression analyses were calculated for evaluation of the independent prognostic impact of MPS results and several cardiac-related patient characteristics with regard to emerging cardiac events. Kaplan-Meier survival- and log rank analyses were calculated for assessment of cardiac event-free survival. Results: Pathological SSS (OR: 3.3), angina (OR: 2.7) and ischemic ECG (OR: 3.0) were independently associated with cardiac events. Patients with pathological SSS (p = 0.005) and ischemic ECG (p = 0.012) had a significantly lower incidence of cardiac event-free survival. Conclusion: Pathological MPS is independently associated with emerging cardiac events predicting a significantly lower incidence of cardiac event-free survival in patients aged =70 years

Ecological time series analysis, 1982-2009. All public and private hospitals in Spain. General population. Incident coronary disease hospitalisation as derived from official hospital discharge data. Annual hospitalisation rates were modelled according to nationwide use of statins, antihypertensive, antidiabetic and antiplatelet drugs, and prevalences of smoking, obesity and overweight. Additive generalised models and mixed Poisson regression models were used for the purpose, taking year as the random-effect variable and adjusting for age, sex, prevalence of vascular risk factors and the number of hospital beds in intensive and coronary care units. Across 28 years and 671.5 million person-years of observation, there were 2 986 834 hospitalisations due to coronary disease; of these, 1 441 980 (48.28%) were classified as incident. Hospitalisation rates increased from 1982 to 1996, with an inflection point in 1997 and a subsequent 52% decrease until 2009. Prevalences of smoking, obesity, overweight and use of vascular risk drug therapy were significantly associated with hospitalisation rates (pcrisis. Future strategies ought to lay special stress on excessive body weight prevention.

    Acute coronary syndromes (ACS) are common, but their incidence and outcome might depend greatly on how data are collected. We compared case ascertainment rates for ACS and myocardial infarction (MI) in a single institution using several different strategies. The Hull and East Yorkshire Hospitals serve a population of ∼560 000. Patients admitted with ACS to cardiology or general medical wards were identified prospectively by trained nurses during 2005. Patients with a death or discharge code of MI were also identified by the hospital information department and, independently, from Myocardial Infarction National Audit Project (MINAP) records. The hospital laboratory identified all patients with an elevated serum troponin-T (TnT) by contemporary criteria (>0.03 µg/L in 2005). The prospective survey identified 1731 admissions (1439 patients) with ACS, including 764 admissions (704 patients) with MIs. The hospital information department reported only 552 admissions (544 patients) with MI and only 206 admissions (203 patients) were reported to the MINAP. Using all 3 strategies, 934 admissions (873 patients) for MI were identified, for which TnT was >1 µg/L in 443, 0.04-1.0 µg/L in 435, ≤0.03 µg/L in 19 and not recorded in 37. A further 823 patients had TnT >0.03 µg/L, but did not have ACS ascertained by any survey method. Of the 873 patients with MI, 146 (16.7%) died during admission and 218 (25.0%) by 1 year, but ranging from 9% for patients enrolled in the MINAP to 27% for those identified by the hospital information department. MINAP and hospital statistics grossly underestimated the incidence of MI managed by our hospital. The 1-year mortality was highly dependent on the method of ascertainment.

    Myocardial perfusion imaging (MPI) has limitations in the presence of balanced multivessel disease (MVD) and left main (LM) coronary artery disease, occasionally resulting in false-normal results despite the high cardiovascular risk associated with this condition. The purpose of this study was to assess the incidence of severe coronary artery disease (CAD) in the presence of a very high Agatston coronary artery calcium (CAC) score (>1,000) in stable symptomatic patients without known CAD but with normal MPI results. A total of 2,659 prospectively acquired consecutive patients were referred for MPI and evaluation of CAC score by CT. Of this patient population, 8 % (222/2,659) had ischemia without myocardial infarction (MI) on MPI and 11 % (298/2,659) had abnormal MPI (MI and/or ischemia). On presentation 1 % of the patients (26/2,659) were symptomatic, had a CAC score >1,000 and normal MPI results. The definition of normal MPI was strict and included a normal hemodynamic response without ischemic ECG changes and normal imaging, particularly absence of transient ischemic dilation. All of these 26 patients with a CAC score >1,000 and normal MPI findings underwent cardiac catheterization. Of these 26 patients, 58 % (15/26) had severe disease (≥70 % stenosis) leading to revascularization. Of this group, 47 % (7/15) underwent percutaneous intervention, and 53 % (8/15) underwent coronary artery bypass grafting. All of these 15 patients had either MVD (14/15) or LM coronary artery disease (1/15), and represented 0.6 % (15/2,659) of all referred patients (95 % CI 0.3 - 0.9 %). The majority, 90 % (8/9), had severe CAD with typical chest pain. A very high CAC score (>1,000) with normal MPI in a small subset of symptomatically stable patients was associated with a moderate incidence of severe CAD (95 % CI 37 - 77 %). Larger studies and/or a meta-analysis of small studies are needed to more precisely estimate the incidence of CAD in this population. This study also supports

    Coronary artery disease (CAD) is a major cause of cardiovascular morbidity and mortality in patients with diabetes mellitus, yet CAD often is asymptomatic prior to myocardial infarction (MI) and coronary death. To assess whether routine screening for CAD by coronary computed tomography angiography (CCTA) in patients with type 1 or type 2 diabetes deemed to be at high cardiac risk followed by CCTA-directed therapy would reduce the risk of death and nonfatal coronary outcomes. The FACTOR-64 study was a randomized clinical trial in which 900 patients with type 1 or type 2 diabetes of at least 3 to 5 years' duration and without symptoms of CAD were recruited from 45 clinics and practices of a single health system (Intermountain Healthcare, Utah), enrolled at a single-site coordinating center, and randomly assigned to CAD screening with CCTA (n = 452) or to standard national guidelines-based optimal diabetes care (n = 448) (targets: glycated hemoglobin level 50 mg/dL [women] or >40 mg/dL [men], triglycerides level <150 mg/dL, systolic blood pressure <120 mm Hg), or aggressive therapy with invasive coronary angiography, was recommended based on CCTA findings. Enrollment occurred between July 2007 and May 2013, and follow-up extended to August 2014. The primary outcome was a composite of all-cause mortality, nonfatal MI, or unstable angina requiring hospitalization; the secondary outcome was ischemic major adverse cardiovascular events (composite of CAD death, nonfatal MI, or unstable angina). At a mean follow-up time of 4.0 (SD, 1.7) years, the primary outcome event rates were not significantly different between the CCTA and the control groups (6.2% [28 events] vs 7.6% [34 events]; hazard ratio, 0.80 [95% CI, 0.49-1.32]; P = .38). The incidence of the composite secondary end point of ischemic major adverse cardiovascular events also did not differ between groups (4.4% [20 events] vs 3.8% [17 events]; hazard ratio, 1.15 [95% CI, 0.60-2.19]; P = .68).

    Aldosterone may have adverse effects in the myocardium and vasculature. Treatment with an aldosterone antagonist reduces cardiovascular risk in patients with acute myocardial infarction complicated by heart failure (HF) and left ventricular systolic dysfunction. However, most patients with acute coronary syndrome do not have advanced HF. Among such patients, it is unknown whether aldosterone predicts cardiovascular risk. To address this question, we examined data from the dal-OUTCOMES trial that compared the cholesteryl ester transfer protein inhibitor dalcetrapib with placebo, beginning 4 to 12 weeks after an index acute coronary syndrome. Patients with New York Heart Association class II (with LVEF coronary heart disease death, nonfatal myocardial infarction, stroke, hospitalization for unstable angina, or resuscitated cardiac arrest. Hospitalization for HF was a secondary endpoint. Over a median follow-up of 37 months, the primary outcome occurred in 366 patients (9.0%), and hospitalization for HF occurred in 72 patients (1.8%). There was no association between aldosterone and either the time to first occurrence of a primary outcome (hazard ratio for doubling of aldosterone 0.92, 95% confidence interval 0.78-1.09, P=0.34) or hospitalization for HF (hazard ratio 1.38, 95% CI 0.96-1.99, P=0.08) in Cox regression models adjusted for covariates. In patients with recent acute coronary syndrome but without advanced HF, aldosterone does not predict major cardiovascular events. URL: http://www.clinicaltrials.gov.

    Type D personality is associated with an increased morbidity and mortality risk in cardiovascular disease patients, but the mechanisms explaining this risk are unclear. We examined whether Type D was associated with coronary artery disease (CAD) risk factors, estimated risk of developing CAD, and previous cardiac events. Cross-sectional study in the general Icelandic population. A random sample of 4753 individuals (mean age 49.1 ± 12.0 years; 49% men) from the REFINE-Reykjavik study completed assessments for Type D personality and conventional CAD risk factors. Ten-year risk of developing CAD was estimated with the Icelandic risk calculator. Type D personality (22% of sample) was associated with a higher prevalence of hypertension (35 vs. 31%, p = 0.009), but less use of hypertension medication (58 vs. 65%, p = 0.013) in hypertensives, more diabetes (6 vs. 4%, p = 0.023), wider waist circumference (p = 0.007), and elevated body mass index (p = 0.025) and blood lipids (p lifestyle-related CAD risk factors, a higher estimated risk of developing CAD, and higher incidence of previous cardiac events. Unhealthy lifestyles may partly explain the adverse cardiovascular effect of Type D personality.

    To examine the association between elevated leukocyte count and hospital mortality and heart failure in patients enrolled in the multinational, observational Global Registry of Acute Coronary Events (GRACE). Elevated leukocyte count is associated with adverse hospital outcomes in patients presenting with acute myocardial infarction (AMI). The association of this prognostic factor with hospital mortality and heart failure in patients with other acute coronary syndromes (ACS) is unclear. We examined the association between admission leukocyte count and hospital mortality and heart failure in 8269 patients presenting with an ACS. This association was examined separately in patients with ST-segment elevation AMI, non-ST-segment elevation AMI, and unstable angina. Leukocyte count was divided into 4 mutually exclusive groups (Q): Q1 12,000. Multiple logistic regression analysis was performed to examine the association between elevated leukocyte count and hospital events while accounting for the simultaneous effect of several potentially confounding variables. Increasing leukocyte count was significantly associated with hospital death (adjusted odds ratio [OR] 2.8, 95% CI 2.1-3.6 for Q4 compared to Q2 [normal range]) and heart failure (OR 2.7, 95% CI 2.2-3.4) for patients presenting with ACS. This association was seen in patients with ST-segment elevation AMI (OR for hospital death 3.2, 95% CI 2.1-4.7; OR for heart failure 2.4, 95% CI 1.8-3.3), non-ST-segment elevation AMI (OR for hospital death 1.9, 95% CI 1.2-3.0; OR for heart failure 1.7, 95% CI 1.1-2.5), or unstable angina (OR for hospital death 2.8, 95% CI 1.4-5.5; OR for heart failure 2.0, 95% CI 0.9-4.4). In men and women of all ages with the spectrum of ACS, initial leukocyte count is an independent predictor of hospital death and the development of heart failure.

    To examine trends in incidence and 28-day case fatality of myocardial infarction (MI) in persons aged 75-99 years in four areas of Finland. The Finnish Acute Myocardial Infarction (FINAMI) register is a population-based MI register study, which during 1995-2012 recorded 30561 suspected acute coronary syndromes in persons aged ≥75 years. Of them, 16229 fulfilled the American Heart Association criteria for a definite, probable or possible MI or coronary death. This age-group contributed 56.8% of all MIs of which 62.7% occurred in women. The incidence of MI decreased by -3.3%/year (95% CI -4.2; -2.4) in women aged 75-84 years, and by -1.2%/year (-1.9; -0.5) in women aged 85-99 years, but among men in these age-groups, only a non-significant reduction occurred. The 28-day case fatality of MI was high. In the age-group 75-84 years, it decreased non-significantly by -1.6%/year in men, and significantly by -2.4%/year (-3.9; -0.8) in women. In the age-group 85-99 years, the decrease was more remarkable: -5.1%/year (-7.8; -2.3) and -3.9%/year (-5.5; -2.2), respectively. In Finland, more than half of MIs occur in the age-group 75-99 years, and most of them in women. The incidence of MI decreased significantly in elderly women but non-significantly in elderly men. The 28-day case fatality decreased especially in the age-group 85-99 years. Key Messages In Finland, more than one half of all myocardial infarctions (MIs) occur in the age-group of 75 years or older. Furthermore, 62.7% of MIs among elderly patients occur among women, although 58.0% of the elderly population are women. The incidence of MI decreased significantly in elderly women but not in elderly men. The 28-day case fatality in elderly patients was high but decreased significantly during the study period 1995-2012. This study provides population-based data on treatment strategies and trends in incidence, event rate, mortality and case fatality of MI in elderly individuals. Elderly patients with acute coronary

    Though much evidence indicates that work stress increases the risk of incident of coronary heart disease (CHD), little is known about the role of work stress in the development of recurrent CHD events. The objective of this study was to review and synthesize the existing epidemiological evidence on whether work stress increases the risk of recurrent CHD events in patients with the first CHD. A systematic literature search in the PubMed database (January 1990 - December 2013) for prospective studies was performed. Inclusion criteria included: peer-reviewed English papers with original data, studies with substantial follow-up (> 3 years), end points defined as cardiac death or nonfatal myocardial infarction, as well as work stress assessed with reliable and valid instruments. Meta-analysis using random-effects modeling was conducted in order to synthesize the observed effects across the studies. Five papers derived from 4 prospective studies conducted in Sweden and Canada were included in this systematic review. The measurement of work stress was based on the Demand- Control model (4 papers) or the Effort-Reward Imbalance model (1 paper). According to the estimation by meta-analysis based on 4 papers, a significant effect of work stress on the risk of recurrent CHD events (hazard ratio: 1.65, 95% confidence interval: 1.23-2.22) was observed. Our findings suggest that, in patients with the first CHD, work stress is associated with an increased relative risk of recurrent CHD events by 65%. Due to the limited literature, more well-designed prospective research is needed to examine this association, in particular, from other than western regions of the world.

  14. The Thrombin Receptor Antagonist for Clinical Event Reduction in Acute Coronary Syndrome (TRA*CER) trial: study design and rationale.

    Science.gov (United States)

    2009-09-01

    The protease-activated receptor 1 (PAR-1), the main platelet receptor for thrombin, represents a novel target for treatment of arterial thrombosis, and SCH 530348 is an orally active, selective, competitive PAR-1 antagonist. We designed TRA*CER to evaluate the efficacy and safety of SCH 530348 compared with placebo in addition to standard of care in patients with non-ST-segment elevation (NSTE) acute coronary syndromes (ACS) and high-risk features. TRA*CER is a prospective, randomized, double-blind, multicenter, phase III trial with an original estimated sample size of 10,000 subjects. Our primary objective is to demonstrate that SCH 530348 in addition to standard of care will reduce the incidence of the composite of cardiovascular death, myocardial infarction (MI), stroke, recurrent ischemia with rehospitalization, and urgent coronary revascularization compared with standard of care alone. Our key secondary objective is to determine whether SCH 530348 will reduce the composite of cardiovascular death, MI, or stroke compared with standard of care alone. Secondary objectives related to safety are the composite of moderate and severe GUSTO bleeding and clinically significant TIMI bleeding. The trial will continue until a predetermined minimum number of centrally adjudicated primary and key secondary end point events have occurred and all subjects have participated in the study for at least 1 year. The TRA*CER trial is part of the large phase III SCH 530348 development program that includes a concomitant evaluation in secondary prevention. TRA*CER will define efficacy and safety of the novel platelet PAR-1 inhibitor SCH 530348 in the treatment of high-risk patients with NSTE ACS in the setting of current treatment strategies.

    Objective of this study was to assess the risk of coronary heart disease (CHD) associated with the combination of employment status and child care among women of working age, also examining the sex of the offspring. Only two previous studies investigated the effect of double burden on CHD, observing an increased risk among employed women with high domestic burden or providing child care, although the relative risks were marginally or not significant. The study population was composed of all women 25-50 years old at 2001 census, living in Turin in families composed only by individuals or couples, with or without children (N = 109,358). Subjects were followed up during 2002-2010 for CHD incidence and mortality through record-linkage of the cohort with the local archives of mortality and hospital admissions. CHD risk was estimated by multivariate Poisson regression models. Among employed women, CHD risk increased significantly by 29% for each child in the household (IRR = 1.29) and by 39% for each son (IRR = 1.39), whereas no association with the presence of children was found among non-employed women or among employed women with daughters. When categorized, the presence of two or more sons significantly increased CHD risk among employed women (IRR = 2.23), compared to those without children. The study found a significant increase in CHD risk associated with the presence of two or more sons in the household, but not daughters, among employed women. This is a new finding, which should be confirmed in other studies, conducted also in countries where the division of domestic duties between males and females is more balanced, such as the European Nordic countries.

    Patients with diabetes mellitus have reduced longevity after acute coronary syndromes and revascularization. However, knowledge of the long-term complication rates and patterns from an everyday life setting is lacking. Consecutive patients undergoing percutaneous coronary intervention included in the Swedish Coronary Angiography Angioplasty Registry (SCAAR) between 2006 and 2010 and with no previous revascularization were prospectively followed up for combined cardiovascular events (first of all-cause mortality, myocardial infarction, stroke, and heart failure) until December 31, 2010. The mean follow-up period was 920 days (SD, 530 days). Differences in background and procedural characteristics were adjusted for in a multivariate Cox regression model. Of 58 891 patients, mean age 67 years, 19% had diabetes mellitus; 27% of them were on diet treatment, 33% on oral glucose lowering, and 40% on insulin treatment. At admission, cardiovascular risk factors, multiple coronary vessel, and left main stem disease were more frequent in patients with diabetes mellitus and their revascularization was less often complete. The adjusted risk for combined cardiovascular events was higher in patients on insulin (hazard ratio [95% confidence interval], 1.63 [1.55-1.72]), on oral treatment (1.23 [1.15-1.31]), and on diet alone (1.21 [1.12-1.29]) compared with patients without diabetes mellitus. Insulin-treated patients ran an increased risk of restenosis (1.54 [1.39-1.71]) and stent thrombosis (1.56 [1.25-1.96]). The prognosis after a first percutaneous coronary intervention is more severe in patients with diabetes mellitus, in particular, in patients treated with insulin, with higher rates of mortality, cardiovascular events, and stent thrombosis over the following 5 years. © 2015 American Heart Association, Inc.

    Non-high-density lipoprotein cholesterol (non-HDLC) levels reflect the full burden of cholesterol transported in atherogenic lipoproteins. Genetic studies suggest a causal association between elevated triglycerides (TGs)-rich lipoproteins and atherosclerosis. We evaluated associations between achieved non-HDLC and TG levels on changes in coronary atheroma volume. Data were analyzed from 9 clinical trials involving 4957 patients with coronary disease undergoing serial intravascular ultrasonography to assess changes in percent atheroma volume (ΔPAV) and were evaluated against on-treatment non-HDLC and TG levels. The effects of lower (0) was associated with achieved TG levels >200 mg/dL, respectively. Lower on-treatment non-HDLC and TG levels associated with significant PAV regression compared with higher non-HDLC and TG levels across all levels of LDLC and C-reactive protein and irrespective of diabetic status (P<0.001 across all comparisons). ΔPAV were more strongly influenced by changes in non-HDLC (β=0.62; P<0.001) compared with changes in LDLC (β=0.51; P<0.001). Kaplan-Meier sensitivity analyses demonstrated significantly greater major adverse cardiovascular event rates in those with higher versus lower non-HDLC and TG levels, with an earlier separation of the non-HDLC compared with the LDLC curve. Achieved non-HDLC levels seem more closely associated with coronary atheroma progression than LDLC. Plaque progression associates with achieved TGs, but only above levels of 200 mg/dL. These observations support a more prominent role for non-HDLC (and possibly TG) lowering in combating residual cardiovascular risk. © 2016 American Heart Association, Inc.

    Chronically ill patients such as people with type 2 diabetes develop perceptions of their illness, which will influence their coping behaviour. Perceptions are formed once a health threat has been recognised. Many people with type 2 diabetes suffer from multimorbidity, for example the combination with cardiovascular disease. Perceptions of one illness may influence perceptions of the other condition. The aim of the current study was to evaluate the effect of an intervention in type 2 diabetes patients with a first acute coronary event on change in illness perceptions and whether this mediates the intervention effect on health status. The current study is a secondary data analysis of a RCT. Two hundred one participants were randomised (1:1 ratio) to the intervention (n = 101, three home visits) or control group (n = 100). Outcome variables were diabetes and acute coronary event perceptions, assessed with the two separate Brief Illness Perceptions Questionnaires (BIPQs); and health status (Euroqol Visual Analog Scale (EQ-VAS)). The intervention effect was analysed using ANCOVA. Linear regression analyses were used to assess whether illness perceptions mediated the intervention effect on health status. A positive intervention effect was found on the BIPQ diabetes items coherence and treatment control (F = 8.19, p = 0.005; F = 14.01, p effect was found on the other BIPQ diabetes items consequence, personal control, identity, illness concern and emotional representation. Regarding the acute coronary event, a positive intervention effect on treatment control was found (F = 7.81, p = 0.006). No intervention effect was found on the other items of the acute coronary event BIPQ. Better diabetes coherence was associated with improved health status, whereas perceiving more treatment control was not. The mediating effect of the diabetes perception 'coherence' on health status was not significant. Targeting illness perceptions of people with

    Positive psychological constructs, especially optimism, have been linked with superior cardiovascular health. However, there has been minimal study of positive constructs in patients with acute coronary syndrome (ACS), despite the prevalence and importance of this condition. Furthermore, few studies have examined multiple positive psychological constructs and multiple cardiac-related outcomes within the same cohort to determine specifically which positive construct may affect a particular cardiac outcome. The Gratitude Research in Acute Coronary Events (GRACE) study examines the association between optimism/gratitude 2weeks post-ACS and subsequent clinical outcomes. The primary outcome measure is physical activity at 6months, measured via accelerometer, and key secondary outcome measures include levels of prognostic biomarkers and rates of nonelective cardiac rehospitalization at 6months. These relationships will be analyzed using multivariable linear regression, controlling for sociodemographic, medical, and negative psychological factors; associations between baseline positive constructs and subsequent rehospitalizations will be assessed via Cox regression. Overall, 164 participants enrolled and completed the baseline 2-week assessment; the cohort had a mean age of 61.5+/?10.5years and was 84% men; this was the first ACS for 58% of participants. The GRACE study will determine whether optimism and gratitude are prospectively and independently associated with physical activity and other critical outcomes in the 6months following an ACS. If these constructs are associated with superior outcomes, this may highlight the importance of these constructs as independent prognostic factors post-ACS. Copyright © 2015 Elsevier Inc.

    In this study, we aimed to establish whether age-sex-specific percentiles of coronary artery calcium (CAC) predict cardiovascular outcomes better than the actual (absolute) CAC score. The presence and extent of CAC correlates with the overall magnitude of coronary atherosclerotic plaque burden and with the development of subsequent coronary events. MESA (Multi-Ethnic Study of Atherosclerosis) is a prospective cohort study of 6,814 asymptomatic participants followed for coronary heart disease (CHD) events including myocardial infarction, angina, resuscitated cardiac arrest, or CHD death. Time to incident CHD was modeled with Cox regression, and we compared models with percentiles based on age, sex, and/or race/ethnicity to categories commonly used (0, 1 to 100, 101 to 400, 400+ Agatston units). There were 163 (2.4%) incident CHD events (median follow-up 3.75 years). Expressing CAC in terms of age- and sex-specific percentiles had significantly lower area under the receiver-operating characteristic curve (AUC) than when using absolute scores (women: AUC 0.73 versus 0.76, p = 0.044; men: AUC 0.73 versus 0.77, p better model fit with the overall score. Both methods robustly predicted events (>90th percentile associated with a hazard ratio [HR] of 16.4, 95% confidence interval [CI]: 9.30 to 28.9, and score >400 associated with HR of 20.6, 95% CI: 11.8 to 36.0). Within groups based on age-, sex-, and race/ethnicity-specific percentiles there remains a clear trend of increasing risk across levels of the absolute CAC groups. In contrast, once absolute CAC category is fixed, there is no increasing trend across levels of age-, sex-, and race/ethnicity-specific categories. Patients with low absolute scores are low-risk, regardless of age-, sex-, and race/ethnicity-specific percentile rank. Persons with an absolute CAC score of >400 are high risk, regardless of percentile rank. Using absolute CAC in standard groups performed better than age-, sex-, and race

    Although the elderly comprise the majority of acute coronary syndrome (ACS) patients, limited data exist on major adverse cardiovascular events (MACEs) and quality of life (QoL). To study MACEs and QoL prospectively in ACS patients >70years referred for coronary angiography. A prospective observational study that included ACS patients >70years undergoing coronary angiography. The outcomes were MACEs and QoL 3years after inclusion. MACEs were defined as death, recurrent ACS, new-onset of heart failure and repeated revascularization by coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI). A QoL questionnaire was completed by the patients along with a physical examination and a personal interview at the 3-year follow-up. Multivariate analysis was performed to identify the predictors for MACEs. In total, 138 patients (mean age 78.8±3.8years) with ACS were included in the study. Mean follow-up was 1196±296days. In all, 42% of the patients had MACEs and 25% had post-ACS heart failure. The mortality rate was 11%. After adjusting for significant cardiovascular risk factors, the following factors were significantly associated with MACEs: Age, high-sensitive troponin T (hsTNT), use of diuretics and reduced left ventricular ejection fraction (LVEF). Furthermore, the QoL evaluated with SF-36 in survivors from ACS at the end of study was similar to the QoL in an age-matched healthy Swedish population. In this prospective study on elderly ACS patients MACEs still occurred in 42% of the cases (despite low mortality and good QoL), with post-ACS heart failure as the most important event.

    Five percent of patients who went through Percutaneous Coronary Intervention (PCI) experienced Major Adverse Cardiac Events (MACE) after PCI procedure. Risk prediction of MACE following a PCI procedure therefore is helpful. This work describes a review of such prediction models currently in use. Literature search was done on PubMed and SCOPUS database. Thirty literatures were found but only 4 studies were chosen based on the data used, design, and outcome of the study. Particular emphasis was given and commented on the study design, population, sample size, modeling method, predictors, outcomes, discrimination and calibration of the model. All the models had acceptable discrimination ability (C-statistics >0.7) and good calibration (Hosmer-Lameshow P-value >0.05). Most common model used was multivariate logistic regression and most popular predictor was age.

    We investigated whether number of recent stressful life events is associated with incident cardiovascular disease (CVD) and whether this relationship is stronger in adults with a history of clinical depression. Prospective data from 28,583 U.S. adults (mean age=45years) initially free of CVD who participated in Waves 1 (2001-2002) and 2 (2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were examined. Number of past-year stressful life events (Wave 1), lifetime depressive disorder (Wave 1), and incident CVD (Wave 2) were determined by structured interviews. There were 1069 cases of incident CVD. Each additional stressful life event was associated with a 15% increased odds of incident CVD [Odds Ratio (OR)=1.15, 95% Confidence Interval (CI): 1.11, 1.19]. As hypothesized, a stressful life events by lifetime depressive disorder interaction was detected (P=0.003). Stratified analyses indicated that stressful life events had a stronger association with incident CVD among adults with (OR=1.18, 95% CI: 1.10, 1.27, n=4908) versus without (OR=1.10, 95% CI: 1.07, 1.14, n=23,675) a lifetime depressive disorder. Our findings suggest that a greater number of recent stressful life events elevate the risk of new-onset CVD and that this risk is potentiated in adults with a history of clinical depression.

    Although previous epidemiological studies have investigated the relationship between sleep duration and various cardiovascular events, the results have been inconsistent. Accordingly, we conducted a follow-up survey to investigate the relationship between sleep duration and cardiovascular events among male workers, accounting for occupational factors that might confound the true relationship. A total of 2282 male employees aged 35-54 years based in a factory in Japan were followed for 14 years. The risk of cardiovascular events was compared among 4 groups stratified based on sleep duration at baseline (hours). Cardiovascular events included stroke, coronary events and sudden cardiac death. The hazard ratios for events were calculated using a Cox proportional hazards model, with the 7-7.9-hour group serving as a reference. The model was adjusted for potential confounders including traditional cardiovascular risk factors and working characteristics. During 14 years of follow-up, 64 cardiovascular events were recorded including 30 strokes, 27 coronary events and 7 sudden cardiac deaths. After adjustment for possible confounders, the hazard ratios for cardiovascular and coronary events in the hour group were 3.49 [95% confidence interval (95% CI) 1.30-9.40] and 4.95 (95% CI 1.31-18.73), respectively. There was no significant increment in the risk of stroke for any sleep duration groups. Short sleep duration (hours) was a significant risk factor for coronary events in a Japanese male working population.

    Monocyte recruitment to damaged endothelium is enhanced by platelet binding to monocytes and contributes to vascular repair. Therefore, we studied whether the number of platelets per monocyte affects the recurrence of adverse events in patients after percutaneous coronary intervention (PCI). Platelet-monocytes complexes with high and low median fluorescence intensities (MFI) of the platelet marker CD42b were isolated using cell sorting. Microscopic analysis revealed that a high platelet marker MFI on monocytes corresponded with a high platelet density per monocyte while a low platelet marker MFI corresponded with a low platelet density per monocyte (3.4 ± 0.7 vs 1.4 ± 0.1 platelets per monocyte, P=0.01). Using real-time video microscopy, we observed increased recruitment of high platelet density monocytes to endothelial cells as compared with low platelet density monocytes (P=0.01). Next, we classified PCI scheduled patients (N=263) into groups with high, medium and low platelet densities per monocyte and assessed the recurrence of adverse events. After multivariate adjustment for potential confounders, we observed a 2.5-fold reduction in the recurrence of adverse events in patients with a high platelet density per monocyte as compared with a low platelet density per monocyte [hazard ratio=0.4 (95% confidence interval, 0.2-0.8), P=0.01]. We show that a high platelet density per monocyte increases monocyte recruitment to endothelial cells and predicts a reduction in the recurrence of adverse events in patients after PCI. These findings may imply that a high platelet density per monocyte protects against recurrence of adverse events.

    Coronary artery disease (CAD) patients who report low distress are considered to be at low psychological risk for clinical events. However, patients with a repressive coping style may fail to detect and report signals of emotional distress. The authors hypothesized that repressive CAD patients are at risk for clinical events, despite low self-rated distress. This was a prospective 5- to 10-year follow-up study, with a mean follow-up of 6.6 years. At baseline, 731 CAD patients filled out Trait-Anxiety (distress), Marlowe-Crowne (defensiveness), and Type D scales; 159 patients were classified as "repressive," 360 as "nonrepressive," and 212 as "Type D." The primary endpoint was a composite of total mortality or myocardial infarction (MI); the secondary endpoint was cardiac mortality/MI. No patients were lost to follow-up; 91 patients had a clinical event (including 35 cardiac death and 32 MI). Repressive patients reported low levels of anxiety, anger and depression at baseline, but were at increased risk for death/MI (21/159 = 13%) compared with nonrepressive patients (22/360 = 6%), p = .009. Poor systolic function, poor exercise tolerance, 3-vessel disease, index MI and Type-D personality--but not depression, anxiety or anger--also independently predicted clinical events. After controlling for these variables, repressive patients still had a twofold increased risk of death/MI, OR = 2.17, 95% CI = 1.10-4.08, p = .025). These findings were replicated for cardiac mortality/MI. CAD patients who use a repressive coping style are at increased risk for clinical events, despite their claims of low emotional distress. This phenomenon may cause an underestimation of the effect of stress on the heart. (PsycINFO Database Record (c) 2008 APA, all rights reserved).

  9. A taurine-supplemented vegan diet may blunt the contribution of neutrophil activation to acute coronary events.

    Science.gov (United States)

    McCarty, Mark F

    2004-01-01

    Neutrophils are activated in the coronary circulation during acute coronary events (unstable angina and myocardial infarction), often prior to the onset of ischemic damage. Moreover, neutrophils infiltrate coronary plaque in these circumstances, and may contribute to the rupture or erosion of this plaque, triggering thrombosis. Activated neutrophils secrete proteolytic enzymes in latent forms which are activated by the hypochlorous acid (HOCl) generated by myeloperoxidase. These phenomena may help to explain why an elevated white cell count has been found to be an independent coronary risk factor. Low-fat vegan diets can decrease circulating leukocytes--neutrophils and monocytes--possibly owing to down-regulation of systemic IGF-I activity. Thus, a relative neutropenia may contribute to the coronary protection afforded by such diets. However, vegetarian diets are devoid of taurine - the physiological antagonist of HOCl--and tissue levels of this nutrient are relatively low in vegetarians. Taurine has anti-atherosclerotic activity in animal models, possibly reflecting a role for macrophage-derived myeloperoxidase in the atherogenic process. Taurine also has platelet-stabilizing and anti-hypertensive effects that presumably could reduce coronary risk. Thus, it is proposed that a taurine-supplemented low-fat vegan diet represents a rational strategy for diminishing the contribution of activated neutrophils to acute coronary events; moreover, such a regimen would work in a number of other complementary ways to promote cardiovascular health. Moderate alcohol consumption, the well-tolerated drug pentoxifylline, and 5-lipoxygenase inhibitors--zileuton, boswellic acids, fish oil--may also have potential in this regard.

    Epidemiology and consequences of surgery in patients with coronary stents are not clearly defined, as well as the impact of different stent types in relationship with timing of surgery. Among 39 362 patients with previous coronary stenting enrolled in a multicenter prospective registry and followed for 5 years, 13 128 patients underwent 17 226 surgical procedures. The cumulative incidence of surgery at 30 days, 6 months, 1 year, and 5 years was 3.6%, 9.4%, 14.3%, and 40.0%, respectively, and of cardiac and noncardiac surgery was 0.8%, 2.1%, 2.6%, and 4.0% and 1.3%, 5.1%, 9.1%, and 31.7%, respectively. We assessed the incidence and the predictors of cardiac death, myocardial infarction, and serious bleeding event within 30 days from surgery. Cardiac death occurred in 438 patients (2.5%), myocardial infarction in 256 (1.5%), and serious bleeding event in 1099 (6.4%). Surgery increased 1.58× the risk of cardiac death during follow-up. Along with other risk factors, the interplay between stent type and time from percutaneous coronary intervention to surgery was independently associated with cardiac death/myocardial infarction. In comparison with bare-metal stent implanted >12 months before surgery, old-generation drug-eluting stent was associated with higher risk of events at any time point. Conversely, new-generation drug-eluting stent showed similar safety as bare-metal stent >12 months and between 6 and 12 months and appeared trendly safer between 0 and 6 months. Surgery is frequent in patients with coronary stents and carries a considerable risk of ischemic and bleeding events. Ischemic risk is inversely related with time from percutaneous coronary intervention to surgery and is influenced by stent type. © 2015 American Heart Association, Inc.

    Some evidence indicates the deterioration of the cardiovascular system during space storms. It is plausible that the space weather conditions during and after hospital admission may affect the risk of coronary events in patients with acute coronary syndromes (ACS). We analyzed the data of 1400 ACS patients who were admitted to the Hospital Lithuanian University of Health Sciences, and who survived for more than 4 days. We evaluated the associations between geomagnetic storms (GS), solar proton events (SPE), and solar flares (SF) that occurred 0-3 days before and after hospital admission and the risk of cardiovascular death (CAD), non-fatal ACS, and coronary artery bypass grafting (CABG) during a period of 1 year; the evaluation was based on the multivariate logistic model, controlling for clinical data. After adjustment for clinical variables, GS occurring in conjunction with SF 1 day before admission increased the risk of CAD by over 2.5 times. GS 2 days after SPE occurred 1 day after admission increased the risk of CAD and CABG by over 2.8 times. The risk of CABG increased by over 2 times in patients admitted during the day of GS and 1 day after SPE. The risk of ACS was by over 1.63 times higher for patients admitted 1 day before or after solar flares.

  16. Clinical review: Bleeding - a notable complication of treatment in patients with acute coronary syndromes: incidence, predictors, classification, impact on prognosis, and management

    Science.gov (United States)

    2013-01-01

    This article focuses on the incidence, predictors, classification, impact on prognosis, and management of bleeding associated with the treatment of acute coronary syndrome. The issue of bleeding complications is related to the continual improvement of ischemic heart disease treatment, which involves mainly (a) the widespread use of coronary angiography, (b) developments in percutaneous coronary interventions, and (c) the introduction of new antithrombotics. Bleeding has become an important health and economic problem and has an incidence of 2.0% to 17%. Bleeding significantly influences both the short- and long-term prognoses. If a group of patients at higher risk of bleeding complications can be identified according to known risk factors and a risk scoring system can be developed, we may focus more on preventive measures that should help us to reduce the incidence of bleeding.

    Continued advancements in congenital cardiac catheterization and interventions have resulted in increased patient and procedural complexity. Anticipation of life-threatening events and required rescue measures is a critical component to preprocedural preparation. We sought to determine the incidence and nature of life-threatening adverse events in congenital and pediatric cardiac catheterization, risk factors, and resources necessary to anticipate and manage events. Data from 8905 cases performed at the 8 participating institutions of the Congenital Cardiac Catheterization Project on Outcomes were captured between 2007 and 2010 [median 1,095/site (range 133-3,802)]. The incidence of all life-threatening events was 2.1 % [95 % confidence interval (CI) 1.8-2.4 %], whereas mortality was 0.28 % (95 % CI 0.18-0.41 %). Fifty-seven life-threatening events required cardiopulmonary resuscitation, whereas 9 % required extracorporeal membrane oxygenation. Use of a risk adjustment model showed that age events. Using this model, standardized life-threatening event ratios were calculated, thus showing that one institution had a life-threatening event rate greater than expected. Congenital cardiac catheterization and intervention can be performed safely with a low rate of life-threatening events and mortality; preprocedural evaluation of risk may optimize preparation of emergency rescue and bailout procedures. Risk predictors (age < 1, hemodynamic vulnerability, and procedure risk category) can enhance preprocedural patient risk stratification and planning.

    Full Text Available Abstract Background Atherosclerosis is a chronic progressive disease often presenting as clinical cardiovascular disease (CVD events. This study evaluated the characteristics of individuals with a diagnosis of atherosclerosis and estimated the incidence of CVD events to assist in the early identification of high-risk individuals. Methods Respondents to the US SHIELD baseline survey were followed for 2 years to observe incident self-reported CVD. Respondents had subclinical atherosclerosis if they reported a diagnosis of narrow or blocked arteries/carotid artery disease without a past clinical CVD event (heart attack, stroke or revascularization. Characteristics of those with atherosclerosis and incident CVD were compared with those who did not report atherosclerosis at baseline but had CVD in the following 2 years using chi-square tests. Logistic regression model identified characteristics associated with atherosclerosis and incident events. Results Of 17,640 respondents, 488 (2.8% reported having subclinical atherosclerosis at baseline. Subclinical atherosclerosis was associated with age, male gender, dyslipidemia, circulation problems, hypertension, past smoker, and a cholesterol test in past year (OR = 2.2 [all p Conclusion Self-report of subclinical atherosclerosis identified an extremely high-risk group with a >25% risk of a CVD event in the next 2 years. These characteristics may be useful for identifying individuals for more aggressive diagnostic and therapeutic efforts.

Although the association between cardiovascular diseases and cognitive impairments (CIs is well known, the prevalence particularly of mild CI in CR and the characteristics of affected patients have been insufficiently investigated so far. Methods: In this prospective observational study, 496 patients (54.5 ± 6.2 years, 79.8% men with coronary artery disease following an acute coronary event (ACE were analyzed. Patients were enrolled within 14 days of discharge from the hospital in a 3-week inpatient CR program. Patients were tested for CI using the Montreal Cognitive Assessment (MoCA upon admission to and discharge from CR. Additionally, sociodemographic, clinical, and physiological variables were documented. The data were analyzed descriptively and in a multivariate stepwise backward elimination regression model with respect to CI. Results: At admission to CR, the CI (MoCA score < 26 was determined in 182 patients (36.7%. Significant differences between CI and no CI groups were identified, and CI group was associated with high prevalence of smoking (65.9 vs 56.7%, P = 0.046, heavy (physically demanding workloads (26.4 vs 17.8%, P < 0.001, sick leave longer than 1 month prior to CR (28.6 vs 18.5%, P = 0.026, reduced exercise capacity (102.5 vs 118.8 W, P = 0.006, and a shorter 6-min walking distance

    Elevated serum bilirubin levels are associated with decreased coronary heart disease (CHD) risk in cross-sectional studies among diabetic patients, but prospective evidence is limited. We investigated the relationship of serum bilirubin levels with incident CHD risk among type 2 diabetes patients. In a prospective study of 2918 type 2 diabetes embedded in the Dongfeng-Tongji cohort, serum total bilirubin (TBil), direct bilirubin (DBil), and indirect bilirubin (IBil) were measured at baseline. Cox proportional hazards models were used to examine the association between serum bilirubin levels and CHD risk. A total of 440 CHD cases were identified during 12,017 person-years of follow-up. Compared with extreme quartiles, the adjusted hazard ratio and 95% confidence interval of incident CHD were 0.74 (0.56-0.99) with P trend = 0.08 in IBil, while in TBil and DBil, the bilirubin-CHD associations were not significant. Moreover, serum TBil and IBil levels were interacted with drinking status on the risk of incident CHD (P interaction = 0.021 and 0.037, respectively), and the associations were evident in ever drinkers. In drinkers, when serum TBil or IBil concentrations increased 1 μmol/L, the CHD risk both decreased 6% (95% CIs 0.89-0.99 and 0.87-1.00, respectively). Serum IBil levels were marginally related to decreased incident CHD risk among type 2 diabetes. Drinking could potentially enhance the associations of serum TBil and DBil levels with incident CHD risk.

    The outcome of patients with chronic heart failure (CHF) following an ischaemic event is poorly understood. We evaluated the management and outcomes of CHF patients presenting with an acute coronary syndrome (ACS) and explored changes in outcomes over time. A total of 5556 patients enrolled in the Australia-New Zealand population of the Global Registry of Acute Coronary Events (GRACE) between 1999 and 2007 were included. Patients with CHF (n = 609) were compared with those without CHF (n = 4947). Patients with CHF were on average 10 years older, were more likely to be female, had more co-morbidities and cardiac risk factors, and were more likely to have a prior history of angina, myocardial infarction, and revascularization by coronary artery bypass graft (CABG) when compared with those without CHF. CHF was associated with a substantial increase in in-hospital renal failure [odds ratio (OR) 1.76, 95% confidence interval (CI) 1.15-2.71], readmission post-discharge (OR 1.47, 95% CI 1.17-1.90), and 6-month mortality (OR 2.25, 95% CI 1.55-3.27). Over the 9 year study period, in-hospital and 6 month mortality in those with CHF declined by absolute rates of 7.5% and 14%, respectively. This was temporally associated with an increase in prescription of thienopyridines, beta-blockers, statins, and angiotensin II receptor blockers, increased rates of coronary angiography, and 31.8% absolute increase in referral rates for cardiac rehabilitation. Acute coronary syndrome patients with pre-existing CHF are a very high risk group and carry a disproportionate mortality burden. Encouragingly, there was a marked temporal improvement in outcomes over a 9 year period with an increase in evidence-based treatments and secondary preventative measures.

    Full Text Available The lack of association found in several cohort studies between dietary saturated fat and coronary heart disease (CHD risk has renewed debate over the link between dietary fats and CHD.We assessed the relationship between plasma phospholipid fatty acid (PFA concentration and incident CHD using a nested case control design within a prospective study (EPIC-Norfolk of 25,639 individuals aged 40-79 years examined in 1993-1997 and followed up to 2009. Plasma PFA concentrations were measured by gas chromatography in baseline samples retrieved from frozen storage. In 2,424 men and women with incident CHD compared with 4,930 controls alive and free of cardiovascular disease, mean follow-up 13 years, saturated PFA (14:0, 16:0,18:0 plasma concentrations were significantly associated with increased CHD risk (odds ratio [OR] 1.75, 95% CI 1.27-2.41, p<0.0001, in top compared to bottom quartiles (Q, and omega-6 polyunsaturated PFA concentrations were inversely related (OR 0.77, 0.60-0.99, p<0.05 after adjusting for age, sex, body mass index, blood pressure, smoking, alcohol intake, plasma vitamin C, social class, education, and other PFAs. Monounsaturated PFA, omega-3 PFA, and trans PFA concentrations were not significantly associated with CHD. Odd chain PFA (15:0, 17:0 concentrations were significantly inversely associated with CHD (OR 0.73, 0.59-0.91, p<0.001, Q4 versus Q1. Within families of saturated PFA or polyunsaturated PFA, significantly heterogeneous relationships with CHD were observed for individual fatty acids.In this study, plasma concentrations of even chain saturated PFA were found to be positively and omega-6 polyunsaturated PFA inversely related to subsequent coronary heart disease risk. These findings are consistent with accumulating evidence suggesting a protective role of omega-6 fats substituting for saturated fats for CHD prevention.

    The effects of loading doses of statins on clinical outcomes in patients with acute coronary syndrome (ACS) and planned invasive management remain uncertain. To determine if periprocedural loading doses of atorvastatin decrease 30-day major adverse cardiovascular events (MACE) in patients with ACS and planned invasive management. Multicenter, double-blind, placebo-controlled, randomized clinical trial conducted at 53 sites in Brazil among 4191 patients with ACS evaluated with coronary angiography to proceed with a percutaneous coronary intervention (PCI) if anatomically feasible. Enrollment occurred between April 18, 2012, and October 6, 2017. Final follow-up for 30-day outcomes was on November 6, 2017. Patients were randomized to receive 2 loading doses of 80 mg of atorvastatin (n = 2087) or matching placebo (n = 2104) before and 24 hours after a planned PCI. All patients received 40 mg of atorvastatin for 30 days starting 24 hours after the second dose of study medication. The primary outcome was MACE, defined as a composite of all-cause mortality, myocardial infarction, stroke, and unplanned coronary revascularization through 30 days. Among the 4191 patients (mean age, 61.8 [SD, 11.5] years; 1085 women [25.9%]) enrolled, 4163 (99.3%) completed 30-day follow-up. A total of 2710 (64.7%) underwent PCI, 333 (8%) underwent coronary artery bypass graft surgery, and 1144 (27.3%) had exclusively medical management. At 30 days, 130 patients in the atorvastatin group (6.2%) and 149 in the placebo group (7.1%) had a MACE (absolute difference, 0.85% [95% CI, -0.70% to 2.41%]; hazard ratio, 0.88; 95% CI, 0.69-1.11; P = .27). No cases of hepatic failure were reported; 3 cases of rhabdomyolysis were reported in the placebo group (0.1%) and 0 in the atorvastatin group. Among patients with ACS and planned invasive management with PCI, periprocedural loading doses of atorvastatin did not reduce the rate of MACE at 30 days. These findings do not support the routine use

    The prognosis of patients with coronary artery disease (CAD) at hospital discharge was constantly varying, and post-discharge risk of ischemic events remain a concern. However, risk prediction tools to identify risk of ischemia for these patients has not yet been reported. We sought to develop a scoring system for predicting long-term ischemic events in CAD patients receiving antiplatelet therapy that would be beneficial in appropriate personalized decision-making for these patients. In this prospective Optimal antiPlatelet Therapy for Chinese patients with Coronary Artery Disease (OPT-CAD, NCT01735305) registry, a total of 14,032 patients with CAD receiving at least one kind of antiplatelet agent were enrolled from 107 centers across China, from January 2012 to March 2014. The risk scoring system was developed in a derivation cohort (enrolled initially 10,000 patients in the database) using a logistic regression model and was subsequently tested in a validation cohort (the last 4,032 patients). Points in risk score was assigned based on the multivariable odds ratio of each factor. Ischemic events were defined as the composite of cardiac death, myocardial infarction or stroke. Ischemic events occurred in 342 (3.4%) patients in the derivation cohort and 160 (4.0%) patients in the validation cohort during 1-year follow-up. The OPT-CAD score, ranging from 0-257 points, consist of 10 independent risk factors, including age (0-71 points), heart rates (0-36 points), hypertension (0-20 points), prior myocardial infarction (16 points), prior stroke (16 points), renal insufficient (21 points), anemia (19 points), low ejection fraction (22 points), positive cardiac troponin (23 points) and ST-segment deviation (13 points). In predicting 1-year ischemic events, the area under receiver operating characteristics curve were 0.73 and 0.72 in derivation and validation cohort, respectively.

    Observational studies have shown a J-shaped relationship between diastolic blood pressure (BP) and cardiovascular events in hypertensive patients with coronary artery disease. We investigated whether the increased risk associated with low diastolic BP reflects elevated pulse pressure (PP). In 22 672 hypertensive patients with coronary artery disease from the CLARIFY registry (Prospective Observational Longitudinal Registry of Patients With Stable Coronary Artery Disease), followed for a median of 5.0 years, BP was measured annually and averaged. The relationships between PP and diastolic BP, alone or combined, and the primary composite outcome (cardiovascular death or myocardial infarction) were analyzed using multivariable Cox proportional hazards models. Adjusted hazard ratios for the primary outcome were 1.62 (95% confidence interval [CI], 1.40-1.87), 1.00 (ref), 1.07 (95% CI, 0.94-1.21), 1.54 (95% CI, 1.32-1.79), and 2.34 (95% CI, 1.95-2.81) for PPhypertensive patients with coronary artery disease persists in patients within the lowest-risk PP range and is therefore unlikely to be solely the consequence of an increased PP reflecting advanced vascular disease.

    Increased platelet aggregation during antiplatelet therapy may predict cardiovascular events in patients with coronary artery disease. The majority of these patients receive aspirin monotherapy. We aimed to investigate whether high platelet-aggregation levels predict cardiovascular events in stable coronary artery disease patients treated with aspirin. We included 900 stable coronary artery disease patients with either previous myocardial infarction, type 2 diabetes mellitus, or both. All patients received single antithrombotic therapy with 75 mg aspirin daily. Platelet aggregation was evaluated 1 hour after aspirin intake using the VerifyNow Aspirin Assay (Accriva Diagnostics) and Multiplate Analyzer (Roche; agonists: arachidonic acid and collagen). Adherence to aspirin was confirmed by serum thromboxane B 2 . The primary end point was the composite of nonfatal myocardial infarction, ischemic stroke, and cardiovascular death. At 3-year follow-up, 78 primary end points were registered. The primary end point did not occur more frequently in patients with high platelet-aggregation levels (first versus fourth quartile) assessed by VerifyNow (hazard ratio: 0.5 [95% CI, 0.3-1.1], P =0.08) or Multiplate using arachidonic acid (hazard ratio: 1.0 [95% CI, 0.5-2.1], P =0.92) or collagen (hazard ratio: 1.4 [95% CI, 0.7-2.8], P =0.38). Similar results were found for the composite secondary end point (nonfatal myocardial infarction, ischemic stroke, stent thrombosis, and all-cause death) and the single end points. Thromboxane B 2 levels did not predict any end points. Renal insufficiency was the only clinical risk factor predicting the primary and secondary end points. This study is the largest to investigate platelet aggregation in stable coronary artery disease patients receiving aspirin as single antithrombotic therapy. We found that high platelet-aggregation levels did not predict cardiovascular events. © 2017 The Authors. Published on behalf of the American Heart

    Acute myocardial infarction (AMI) is a leading cause of mortality in Asia. However, quantitative risk scores to predict mortality after AMI were developed without the participation of Asian countries. We evaluated the performance of the Global Registry of Acute Coronary Events (GRACE) in-hospital mortality risk score, directly and after recalibration, in a large Singaporean cohort representing 3 major Asian ethnicities. The GRACE cohort included 11,389 patients, predominantly of European descent, hospitalized for AMI or unstable angina from 2002 to 2003. The Singapore cohort included 10,100 Chinese, 3,005 Malay, and 2,046 Indian patients hospitalized for AMI from 2002 to 2005.Using the original GRACE score, predicted in-hospital mortality was 2.4% (Chinese), 2.0% (Malay), and 1.6% (Indian). However, observed in-hospital mortality was much greater at 9.8% (Chinese), 7.6% (Malay), and 6.4% (Indian). The c statistic for Chinese, Malays, and Indians was 0.86, 0.86, and 0.84, respectively, and the Hosmer-Lemeshow statistic was 250, 56, and 41, respectively. Recalibration of the GRACE score, using the mean-centered constants derived from the Singapore cohort, did not change the c statistic but substantially improved the Hosmer-Lemeshow statistic to 90, 24, and 18, respectively. The recalibrated GRACE score predicted in-hospital mortality as follows: 7.7% (Chinese), 6.0% (Malay), and 5.2% (Indian). In this large cohort of 3 major Asian ethnicities, the original GRACE score, derived from populations outside Asia, underestimated in-hospital mortality after AMI. Recalibration improved risk estimation substantially and may help adapt externally developed risk scores for local practice. Copyright © 2011 Mosby, Inc. All rights reserved.

    Full Text Available Background: According to some international studies, patients with acute coronary syndrome (ACS and increased left atrial volume index (LAVI have worse long-term prognosis. However, national Brazilian studies confirming this prediction are still lacking. Objective: To evaluate LAVI as a predictor of major cardiovascular events (MCE in patients with ACS during a 365-day follow-up. Methods: Prospective cohort of 171 patients diagnosed with ACS whose LAVI was calculated within 48 hours after hospital admission. According to LAVI, two groups were categorized: normal LAVI (≤ 32 mL/m2 and increased LAVI (> 32 mL/m2. Both groups were compared regarding clinical and echocardiographic characteristics, in- and out-of-hospital outcomes, and occurrence of ECM in up to 365 days. Results: Increased LAVI was observed in 78 patients (45%, and was associated with older age, higher body mass index, hypertension, history of myocardial infarction and previous angioplasty, and lower creatinine clearance and ejection fraction. During hospitalization, acute pulmonary edema was more frequent in patients with increased LAVI (14.1% vs. 4.3%, p = 0.024. After discharge, the occurrence of combined outcome for MCE was higher (p = 0.001 in the group with increased LAVI (26% as compared to the normal LAVI group (7% [RR (95% CI = 3.46 (1.54-7.73 vs. 0.80 (0.69-0.92]. After Cox regression, increased LAVI increased the probability of MCE (HR = 3.08, 95% CI = 1.28-7.40, p = 0.012. Conclusion: Increased LAVI is an important predictor of MCE in a one-year follow-up.

    Observational studies have raised concerns that high-potency statins increase the risk of acute kidney injury. We therefore examined the incidence of kidney injury across 2 randomized trials of statin therapy. PROVE IT-TIMI 22 enrolled 4162 subjects after an acute coronary syndrome (ACS) and randomized them to atorvastatin 80 mg/day versus pravastatin 40 mg/day. A-to-Z enrolled 4497 subjects after ACS and randomized them to a high-potency (simvastatin 40 mg/day × 1 months, then simvastatin 80 mg/day) versus a delayed moderate-potency statin strategy (placebo × 4 months, then simvastatin 20 mg/day). Serum creatinine was assessed centrally at serial time points. Adverse events (AEs) relating to kidney injury were identified through database review. Across both trials, mean serum creatinine was similar between treatment arms at baseline and throughout follow-up. In A-to-Z, the incidence of a 1.5-fold or ≥ 0.3 mg/dL rise in serum creatinine was 11.4% for subjects randomized to a high-potency statin regimen versus 12.4% for those on a delayed moderate-potency regimen (odds ratio [OR], 0.91; 95% confidence interval [CI], 0.76 to 1.10; P=0.33). In PROVE IT-TIMI 22, the incidence was 9.4% for subjects randomized to atorvastatin 80 mg/day and 10.6% for subjects randomized to pravastatin 40 mg/day (OR, 0.88; 95% CI, 0.71 to 1.09; P=0.25). Consistent results were observed for different kidney injury thresholds and in individuals with diabetes mellitus or with moderate renal dysfunction. The incidence of kidney injury-related adverse events (AEs) was not statistically different for patients on a high-potency versus moderate-potency statin regimen (OR, 1.06; 95% CI, 0.68 to 1.67; P=0.78). For patients enrolled in 2 large randomized trials of statin therapy after ACS, the use of a high-potency statin regimen did not increase the risk of kidney injury.

    Adverse events are unintended patient injuries or complications that arise from health care management resulting in death, disability or prolonged hospital stay. Adverse events that require critical care are a considerable financial burden to the health care system, but also their global impact on patients and society is probably underestimated. The objectives of this systematic review were to synthesize the best available evidence regarding the estimates of the incidence and preventability of adverse events that necessitate intensive care admission, to determine the type and consequences [mortality, length of intensive care unit (ICU) stay and costs] of these adverse events. MEDLINE (from 1966 to present), EMBASE (from 1974 to present) and CENTRAL (version 1-2010) were searched for studies reporting on unplanned admissions on ICUs. Several other sources were searched for additional studies. Only quantitative studies that used chart review for the detection of adverse events requiring intensive care admission were considered for eligibility. For the purposes of this systematic review, ICUs were defined as specialized hospital facilities which provide continuous monitoring and intensive care for acutely ill patients. Studies that were published in the English, Dutch, German, French or Spanish language were eligible for inclusion. Two reviewers independently extracted data and assessed the methodological quality of the included studies. A total of 27 studies were reviewed. Meta-analysis of the data was not appropriate because of methodological and statistical heterogeneity between studies; therefore, results are presented in a descriptive way. The percentage of surgical and medical adverse events that required ICU admission ranged from 1.1% to 37.2%. ICU readmissions varied from 0% to 18.3%. Preventability of the adverse events varied from 17% to 76.5%. Preventable adverse events are further synthesized by type of event. Consequences of the adverse events included a

    The aim of this study was to identify the characteristics of perioperative convulsion and to suggest possible correcting strategies. The multi-centre study was conducted prospectively in 22 hospitals across Thailand in 2015. The occurrences of perioperative adverse events were collected. The data was collated by site manager and forwarded to the data management unit. All perioperative convulsion incidences were enrolled and analysed. The consensus was documented for the relevant factors and the corrective strategies. Descriptive statistics were used. From 2,000 incident reports, perioperative convulsions were found in 16 patients. Six episodes (37.5%) were related to anaesthesia, 31.3% to patients, 18.8% to surgery, and 12.5% to systemic processes. The contributing factor was an inexperienced anaesthesia performer (25%), while the corrective strategy was improvements to supervision (43.8%). Incidents of perioperative convulsion were found to be higher than during the last decade. The initiation and maintenance of safe anaesthesia should be continued.

  2. Operating Experience from Events Reported to the IAEA Incident Reporting System for Research Reactors

    International Nuclear Information System (INIS)

    2015-03-01

    Operating experience feedback is an effective mechanism in providing lessons learned from events and the associated corrective actions to prevent them, helping to improve safety at nuclear installations. The Incident Reporting System for Research Reactors (IRSRR), which is operated by the IAEA, is an important tool for international exchange of operating experience feedback for research reactors. The IRSRR reports contain information on events of safety significance with their root causes and lessons learned which help in reducing the occurrence of similar events at research reactors. To improve the effectiveness of the system, it is essential that national organizations demonstrate an appropriate interest for the timely reporting of events important to safety and share the information in the IRSRR database. At their biennial technical meetings, the IRSRR national coordinators recommended collecting the operating experience from the events reported to the IRSRR and disseminating it in an IAEA publication. This publication highlights the root causes, safety significance, lessons learned, corrective actions and the causal factors for the events reported to the IRSRR up to September 2014. The publication also contains relevant summary information on research reactor events from sources other than the IRSRR, operating experience feedback from the International Reporting System for Operating Experience considered relevant to research reactors, and a description of the elements of an operating experience programme as established by the IAEA safety standards. This publication will be of use to research reactor operating organizations, regulators and designers, and any other organizations or individuals involved in the safety of research reactors

    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 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. © 2015 by the Society for Experimental Biology and Medicine.

    Data are sparse regarding which blood pressure (BP) components in young adulthood optimally determine cardiovascular disease (CVD) by middle age. To assess which BP components best determine incident CVD events in young adults and determine whether these associations vary by race and age at BP measurement. Using data from the Coronary Artery Risk Development in Young Adults (CARDIA) study, this study assessed the longitudinal race-stratified associations between BP and cardiovascular outcomes. CARDIA is a community-based cohort that recruited black and white individuals (age range, 18-30 years) from March 26, 1985, through June 7, 1986. CARDIA followed up participants for up to 28 years, and 94% of the surviving cohort completed at least 1 telephone interview or examination from August 2009 through August 2014. Blood pressures measubred at baseline (Y0) and 15 years later (Y15). Composite CVD events, including coronary heart disease, stroke, heart failure, and other vascular diseases. A total of 4880 participants participated in the study (mean [SD] age, 24.9 [3.6] years at Y0 and 25.0 [3.6] years at Y15; 2223 male [45.6%] at Y0 and 1800 [44.2%] at Y15; 2657 female [54.4%] at Y0 and 2277 [55.8%] at Y0; 2473 black individuals [50.7%] at Y0 and 1994 [48.9%] at Y15; and 2407 white individuals [49.3%] at Y0 and 2083 [51.1%] at Y15). The mean SBP/DBP was 112/69 mm Hg in blacks and 109/68 mm Hg in whites at Y0 and 117/77 mm Hg in blacks and 110/72 mm Hg in whites at Y15. During a 25-year follow-up from Y0, 210 CVD events occurred (twice as many events in blacks [n = 140] compared with whites), of which 131 (87 in blacks) occurred after Y15. With adjustments for covariates, results from Cox proportional hazards models, including SBP and DBP, jointly suggested that, at Y0, SBP (hazard ratio [HR] per 1-SD increase, 1.32; 95% CI, 1.09-1.61) but not DBP (HR, 1.05; 95% CI, 0.88-1.26) was associated with CVD risk in blacks, whereas DBP (HR, 1.74; 95% CI, 1.21-2.50) but not

    Full Text Available OBJECTIVE: To assess safety and efficacy of coronary angioplasty with stent implantation in unstable coronary syndromes. METHODS: Retrospective analysis of in-hospital and late evolution of 74 patients with unstable coronary syndromes (unstable angina or infarction without elevation of the ST segment undergoing coronary angioplasty with stent placement. These 74 patients were compared with 31 patients with stable coronary syndromes (stable angina or stable silent ischemia undergoing the same procedure. RESULTS: No death and no need for revascularization of the culprit artery occurred in the in-hospital phase. The incidences of acute non-Q-wave myocardial infarction were 1.4% and 3.2% (p=0.6 in the unstable and stable coronary syndrome groups, respectively. In the late follow-up (11.2±7.5 months, the incidences of these events combined were 5.7% in the unstable coronary syndrome group and 6.9% (p=0.8 in the stable coronary syndrome group. In the multivariate analysis, the only variable with a tendency to significance as an event predictor was diabetes mellitus (p=0.07; OR=5.2; 95% CI=0.9-29.9. CONCLUSION: The in-hospital and late evolutions of patients with unstable coronary syndrome undergoing angioplasty with intracoronary stent implantation are similar to those of the stable coronary syndrome group, suggesting that this procedure is safe and efficacious when performed in unstable coronary syndrome patients.

    Histidine is a semiessential amino acid with antioxidant and anti-inflammatory properties. Few data are available on the associations between genetic variants, histidine levels, and incident coronary heart disease (CHD) in a population-based sample. By conducting whole exome sequencing on 1152 African Americans in the Atherosclerosis Risk in Communities (ARIC) study and focusing on loss-of-function (LoF) variants, we identified 3 novel rare LoF variants in HAL, a gene that encodes histidine ammonia-lyase in the first step of histidine catabolism. These LoF variants had large effects on blood histidine levels (β=0.26; P=1.2×10(-13)). The positive association with histidine levels was replicated by genotyping an independent sample of 718 ARIC African Americans (minor allele frequency=1%; P=1.2×10(-4)). In addition, high blood histidine levels were associated with reduced risk of developing incident CHD with an average of 21.5 years of follow-up among African Americans (hazard ratio=0.18; P=1.9×10(-4)). This finding was validated in an independent sample of European Americans from the Framingham Heart Study (FHS) Offspring Cohort. However, LoF variants in HAL were not directly significantly associated with incident CHD after meta-analyzing results from the CHARGE Consortium. Three LoF mutations in HAL were associated with increased histidine levels, which in turn were shown to be inversely related to the risk of CHD among both African Americans and European Americans. Future investigations on the association between HAL gene variation and CHD are warranted. © 2015 American Heart Association, Inc.

    In 2009, researchers from Johns Hopkins University's Armstrong Institute for Patient Safety and Quality; public agencies, including the FDA; and private partners, including the Emergency Care Research Institute and the University HealthSystem Consortium (UHC) Safety Intelligence Patient Safety Organization, sought to form a public-private partnership for the promotion of patient safety (P5S) to advance patient safety through voluntary partnerships. The study objective was to test the concept of the P5S to advance our understanding of safety issues related to ventilator events, to develop a common classification system for categorizing adverse events related to mechanical ventilators, and to perform a comparison of adverse events across different adverse event reporting systems. We performed a cross-sectional analysis of ventilator-related adverse events reported in 2012 from the following incident reporting systems: the Pennsylvania Patient Safety Authority's Patient Safety Reporting System, UHC's Safety Intelligence Patient Safety Organization database, and the FDA's Manufacturer and User Facility Device Experience database. Once each organization had its dataset of ventilator-related adverse events, reviewers read the narrative descriptions of each event and classified it according to the developed common taxonomy. A Pennsylvania Patient Safety Authority, FDA, and UHC search provided 252, 274, and 700 relevant reports, respectively. The 3 event types most commonly reported to the UHC and the Pennsylvania Patient Safety Authority's Patient Safety Reporting System databases were airway/breathing circuit issue, human factor issues, and ventilator malfunction events. The top 3 event types reported to the FDA were ventilator malfunction, power source issue, and alarm failure. Overall, we found that (1) through the development of a common taxonomy, adverse events from 3 reporting systems can be evaluated, (2) the types of events reported in each database were related

    Admission hyperglycemia is associated with high inhospital and long-term adverse events in patients that undergo primary percutaneous coronary intervention (PCI). We aimed to evaluate whether hyperglycemia predicts inhospital mortality. We prospectively analyzed 503 consecutive patients. The patients were divided into tertiles according to the admission glucose levels. Tertile I: glucose 145 mg/dL (n = 169). Inhospital mortality was 0 in tertile I, 2 in tertile II, and 9 in tertile III (P < .02). Cardiogenic shock occurred more frequently in tertile III compared to tertiles I and II (10% vs 4.1% and 0.6%, respectively, P = .01). Multivariate logistic regression analysis revealed that patients in tertile III had significantly higher risk of inhospital major adverse cardiac events compared to patients in tertile I (odds ratio: 9.55, P < .02). Admission hyperglycemia predicts inhospital adverse cardiac events in mortality and acute ST-segment elevation myocardial infarction in patients that underwent primary PCI.

    Adverse events (AE) in trial populations present a major burden to researchers and patients, yet most events are unrelated to investigational treatment. We aimed to develop a coherent list of expected AEs, whose incidence can be predicted by patient characteristics that will inform future trials and perhaps general poststroke care. We analyzed raw AE data from patients participating in acute ischemic stroke trials. We identified events that occurred with a lower 99% confidence bound greater than nil. Among these, we applied receiver operating characteristic principles to select the fewest types of events that together represented the greatest number of reports. Using ordinal logistic regression, we modeled the incidence of these events as a function of patient age, sex, baseline National Institutes of Health Stroke Scale, and multimorbidity status, defining Ppatients, reporting 21 217 AEs. Among 756 types of AEs, 132 accounted for 82.7%, of which 80% began within 10 days after stroke. Right hemisphere (odds ratio [OR], 1.67), increasing baseline National Institutes of Health Stroke Scale (OR, 1.11), multimorbidity status (OR, 1.09 per disease), patient age (OR, 1.01 per year), height (OR, 1.01 per centimeter), diastolic blood pressure (OR, 0.99 per mm Hg), and smoking (OR, 0.82) were independently associated with developing more AEs but together explained only 13% of the variation. A list of 132 expected AEs after acute ischemic stroke may be used to simplify interpretation and reporting of complications. AEs can be modestly predicted by patient characteristics, facilitating stratification of patients by risk for poststroke complications. © 2014 American Heart Association, Inc.

    Modifiable lifestyle-related factors are associated with risk of coronary heart disease and may also influence kidney disease risk. Community-based prospective cohort study. 2,354 African American and white participants aged 28-40 years without baseline microalbuminuria or estimated glomerular filtration rate food habits, obesity, and diet quality, which was based on 8 fundamental components of the Dietary Approaches to Stop Hypertension (DASH) diet, including increased intake of fruits, vegetables, low-fat dairy products, whole grains, and nuts and legumes and reduced intake of sodium, sugar-sweetened beverages, and red and processed meats. Spot urine albumin-creatinine ratios were obtained at baseline (1995-1996) and three 5-year follow-up examinations (5, 10, and 15 years' follow-up). Incident microalbuminuria was defined as the presence of age- and sex-adjusted albumin-creatinine ratio ≥25 mg/g at 2 or more of the successive follow-up examinations. During the 15-year follow-up, 77 (3.3%) individuals developed incident microalbuminuria. After multivariable adjustment, poor diet quality (OR, 2.0; 95% CI, 1.1-3.4) and obesity (OR, 1.9; 95% CI, 1.1-3.3) were associated significantly with microalbuminuria; current smoking (OR, 1.6; 95% CI, 0.9-2.8) was associated with microalbuminuria, although the CI crossed 1.0. Neither low physical activity (OR, 1.0; 95% CI, 0.5-1.8) nor fast food consumption (OR, 1.2; 95% CI, 0.7-2.3) was associated with microalbuminuria. Compared with individuals with no unhealthy lifestyle-related factors (poor diet quality, current smoking, and obesity), adjusted odds of incident microalbuminuria were 131%, 273%, and 634% higher for the presence of 1 (OR, 2.3; 95% CI, 1.3-4.3), 2 (OR, 3.7; 95% CI, 1.8-7.7), and 3 (OR, 7.3; 95% CI, 2.1-26.1) unhealthy lifestyle-related factors.

    Percutaneous coronary intervention (PCI) after transcatheter aortic valve implantation (TAVI) can become technically challenging after implantation of the self-expanding Medtronic CoreValve (MCV) device, which completely covers the aortic root. The aim of this study was to report on the incidence, feasibility and outcome of PCI after TAVI with the MCV device. Between 2007 and 2014, all patients subjected to PCI after MCV implantation in a single-center institutional TAVI database were retrospectively identified. Clinical, angiographic and procedural characteristics were reviewed and analyzed. We identified a total of 17 patients (5.7%) treated with 24 PCI procedures for 29 lesions at a median of 17.7months (range 1-72) after MCV implantation. The mean age was 79.7±6.8years and the mean logistic EuroSCORE was 30.3%±18.9%. Nine procedures were performed for patients with acute coronary syndrome. 89.6% of the treated lesions were of type B2/C and 79.3% were de novo ones. A median of one guiding catheter was necessary to intubate the target coronary ostium (range 1-10) and 95% of the lesions on the left coronary artery were treated through a Judkins catheter. In one primary PCI for STEMI the intubation of the right coronary ostium was not successful. Final procedural success was obtained in 95.8%, and peri-procedural death occurred in one patient. The need for PCI after MCV is not uncommon and is mostly related to coronary artery disease progression. PCI after MCV is usually feasible and safe, but coronary intubation in an emergency setting can be challenging. Copyright © 2016 Elsevier Inc. All rights reserved.

    Apolipoprotein C-III (apoC-III) is a key regulator of triglyceride metabolism. Elevated triglyceride-rich lipoproteins and apoC-III levels are causally linked to coronary artery disease (CAD) risk. The mechanism(s) through which apoC-III increases CAD risk remains largely unknown. The aim was to confirm the association between apoC-III plasma levels and CAD risk and to explore which lipoprotein subfractions contribute to this relationship between apoC-III and CAD risk. Plasma apoC-III levels were measured in baseline samples from a nested case-control study in the European Prospective Investigation of Cancer (EPIC)-Norfolk study. The study comprised 2711 apparently healthy study participants, of whom 832 subsequently developed CAD. We studied the association of baseline apoC-III levels with incident CAD risk, lipoprotein subfractions measured by nuclear magnetic resonance spectroscopy and inflammatory biomarkers. ApoC-III levels were significantly associated with CAD risk (odds ratio, 1.91; 95% confidence interval, 1.48-2.48 for highest compared with lowest quintile), retaining significance after adjustment for traditional CAD risk factors (odds ratio, 1.47; 95% confidence interval, 1.11-1.94). ApoC-III levels were positively correlated with triglyceride levels, ( r =0.39), particle numbers of very-low-density lipoprotein ( r =0.25), intermediate-density lipoprotein ( r =0.23), small dense low-density lipoprotein ( r =0.26), and high-sensitivity C-reactive protein ( r =0.15), whereas an inverse correlation was observed with large low-density lipoprotein particle number ( r =-0.11), P C-reactive protein. ApoC-III levels are significantly associated with incident CAD risk. Elevated levels of remnant lipoproteins, small dense low-density lipoprotein, and low-grade inflammation may explain this association. © 2017 American Heart Association, Inc.

    Among adults, skipping meals is associated with excess body weight, hypertension, insulin resistance, and elevated fasting lipid concentrations. However, it remains unknown whether specific eating habits regardless of dietary composition influence coronary heart disease (CHD) risk. The objective of this study was to prospectively examine eating habits and risk of CHD. Eating habits, including breakfast eating, were assessed in 1992 in 26 902 American men 45 to 82 years of age from the Health Professionals Follow-up Study who were free of cardiovascular disease and cancer. During 16 years of follow-up, 1527 incident CHD cases were diagnosed. Cox proportional hazards models were used to estimate relative risks and 95% confidence intervals for CHD, adjusted for demographic, diet, lifestyle, and other CHD risk factors. Men who skipped breakfast had a 27% higher risk of CHD compared with men who did not (relative risk, 1.27; 95% confidence interval, 1.06-1.53). Compared with men who did not eat late at night, those who ate late at night had a 55% higher CHD risk (relative risk, 1.55; 95% confidence interval, 1.05-2.29). These associations were mediated by body mass index, hypertension, hypercholesterolemia, and diabetes mellitus. No association was observed between eating frequency (times per day) and risk of CHD. Eating breakfast was associated with significantly lower CHD risk in this cohort of male health professionals.

    Full Text Available Purpose: This study aims to assess the incidence of major life events during graduate medical education (GME training and to establish any associations with modifiable activities and career planning. Methods: The authors surveyed graduating GME trainees from their parent institution in June 2013. Demographic information (clinical department, gender, training duration and major life events (marriage, children, death/illness, home purchase, legal troubles, property loss were surveyed. Respondents were queried about the relationship between life events and career planning. A multivariable logistic regression model tested for associations. Results: A total of 53.2% (166/312 of graduates responded to the survey. 50% (83/166 of respondents were female. Major life events occurred in 96.4% (160/166 of respondents. Male trainees were more likely (56.1% [46/82] vs. 30.1% [25/83] to have a child during training (p=0.01. A total of 41.6% (69/166 of responders consciously engaged or avoided activities during GME training, while 31.9% (53/166 of responders reported that life events influenced their career plans. Trainees in lifestyle residencies (p=0.02, those who experienced the death or illness of a close associate (p=0.01, and those with legal troubles (p=0.04 were significantly more likely to consciously control life events. Conclusion: Major life events are very common and changed career plans in nearly a third of GME trainees. Furthermore, many trainees consciously avoided activities due to their responsibilities during training. GME training programs should closely assess the institutional support systems available to trainees during this difficult time.

    The IAEA convened the 1996 Joint Meeting to Exchange Information on Recent Events in Nuclear Power Plants and the Technical Committee-Annual Meeting of the Incident Reporting System (IRS) national co-ordinators, organized jointly with the Nuclear Energy Agency (NEA) of the OECD in Paris, France from 22-26 April 1996. These consecutive meetings took place at the OECD Headquarters, 2 rue Andre Pascal. The main objective of the first meeting (22-24 April 1996) was to exchange and discuss information on recent events which occurred in NPPs. The second meeting (25-26 April 1996) was devoted to the IAEA and NEA activity in the framework of the IRS. The main issues of the programme at the meetings were as follows: in-depth discussion on NPP recent events, presented by the participants; panel discussion on operational safety experience issues identified by the participants; IAEA and NEA activities on IRS subjects in 1995-1996 and plans for the future; issues from the inter-agency's IRS Advisory Committee. Annexes I and II provide more information on the programme at the meetings. A list of participants is given in Annex III (50 participants from 22 countries and 3 international organization).

    In both clinical development and post-marketing of a new therapy or a new treatment, incidence of an adverse event (AE) is always a concern. When sample sizes are small, large sample-based inferential approaches on an AE incidence proportion in a certain time period no longer apply. In this brief discussion, we introduce a simple Bayesian framework to quantify, in small sample studies and the rare AE case, (1) the confidence level that the incidence proportion of a particular AE p is over or below a threshold, (2) the lower or upper bounds on p with a certain level of confidence, and (3) the minimum required number of patients with an AE before we can be certain that p surpasses a specific threshold, or the maximum allowable number of patients with an AE after which we can no longer be certain that p is below a certain threshold, given a certain confidence level. The method is easy to understand and implement; the interpretation of the results is intuitive. This article also demonstrates the usefulness of simple Bayesian concepts when it comes to answering practical questions.

    Few instruments capture symptoms that predict cardiac events in the short-term. This study examines the ability of the McSweeney Acute and Prodromal Myocardial Infarction Symptom Survey to predict acute cardiac events within 3 months of administration and to identify the prodromal symptoms most associated with short-term risk in women without known coronary heart disease. The McSweeney Acute and Prodromal Myocardial Infarction Symptom Survey was administered to 1,097 women referred to a cardiologist for initial coronary heart disease evaluation. Logistic regression models were used to examine prodromal symptoms individually and in combination to identify the subset of symptoms most predictive of an event within 3 months. Fifty-one women had an early cardiac event. In bivariate analyses, 4 of 30 prodromal symptoms were significantly associated with event occurrence within 90 days. In adjusted analyses, women reporting arm pain or discomfort and unusual fatigue were more likely (OR, 4.67; 95% CI, 2.08-10.48) to have a cardiac event than women reporting neither. The McSweeney Acute and Prodromal Myocardial Infarction Symptom Survey may assist in predicting short-term coronary heart disease events in women without known coronary heart disease.

    Highlights: • Patients developing UAP had overall more atherosclerosis as patients without any events. • Patients developing MACE had only more mixed plaque as those developing UAP. • Different atherosclerotic plaque components by CTA carry different prognostic value. - Abstract: Objective: CT angiography (CTA) has prognostic value in patients. But it is unknown whether differences in atherosclerosis by CTA predict the development of unstable angina pectoris (UAP) vs. major adverse cardiac events (MACE). Methods: We followed patients undergoing CTA as part of their acute chest pain work-up. Primary outcome was the development of UAP or MACE (cardiac death, myocardial infarction, revascularization) during a minimum follow-up of 12-months. CTAs were assessed for extent and composition of coronary plaque and stenosis. Ordinal regression with a 3-level outcome (no events, UAP, MACE) was applied. Results: Among 315 patients, 22 developed UAP and 31 MACE. While UAP patients had higher atherosclerosis burden with respect to all assessed features compared to patients with no events (p ≤ 0.02), only mixed plaque extent was significantly different between UAP and MACE patients (p = 0.02). The odds ratio was 4.55 for being in a higher disease-level comparing patients with low extent to those with no mixed plaque, and 3.02 comparing patients with high to those with low. These findings remained after adjustments for potential confounders. Conclusion: The extent of mixed coronary plaque is different between patients who develop UAP vs. MACE, supporting the hypothesis that it is a more culprit morphology.

    Full Text Available BACKGROUND: Glucose, insulin and Homeostasis Model Assessment Insulin Resistance (HOMA-IR are markers of insulin resistance. The objective of this study is to compare fasting glucose, fasting insulin concentrations and HOMA-IR in strength of association with incident cardiovascular disease. METHODS: We searched the PubMed, MEDLINE, EMBASE, Web of Science, ScienceDirect and Cochrane Library databases from inception to March, 2011, and screened reference lists. Cohort studies or nested case-control studies that investigated the association between fasting glucose, fasting insulin or HOMA-IR and incident cardiovascular disease, were eligible. Two investigators independently performed the article selection, data extraction and risk of bias assessment. Cardiovascular endpoints were coronary heart disease (CHD, stroke or combined cardiovascular disease. We used fixed and random-effect meta-analyses to calculate the pooled relative risk for CHD, stroke and combined cardiovascular disease, comparing high to low concentrations of glucose, insulin or HOMA-IR. Study heterogeneity was calculated with the I(2 statistic. To enable a comparison between cardiovascular disease risks for glucose, insulin and HOMA-IR, we calculated pooled relative risks per increase of one standard deviation. RESULTS: We included 65 studies (involving 516,325 participants in this meta-analysis. In a random-effect meta-analysis the pooled relative risk of CHD (95% CI; I(2 comparing high to low concentrations was 1.52 (1.31, 1.76; 62.4% for glucose, 1.12 (0.92, 1.37; 41.0% for insulin and 1.64 (1.35, 2.00; 0% for HOMA-IR. The pooled relative risk of CHD per one standard deviation increase was 1.21 (1.13, 1.30; 64.9% for glucose, 1.04 (0.96, 1.12; 43.0% for insulin and 1.46 (1.26, 1.69; 0.0% for HOMA-IR. CONCLUSIONS: The relative risk of cardiovascular disease was higher for an increase of one standard deviation in HOMA-IR compared to an increase of one standard deviation in fasting

    Recent demographic changes have led to an increased risk of major vascular events among patients undergoing non-cardiac surgery. Troponin and electrocardiogram monitoring would further identify these major vascular events. Methods: we prospectively collected data on eligible patients (non-selected individuals aged 45 or older undergoing non-cardiac surgery under general or regional anesthesia in two hospitals in Bucaramanga, with expected length of stay longer than 24 hours) during a time-interrupted series,before and after postoperative diagnostic monitoring (blinded assessment of troponin T and electrocardiograms ignoring clinical data). For the period before the intervention (usual clinical care),two independent reviewers extracted clinical information from clinical histories (of all eligible patients from 3 randomly-selected months of 2005). For the period after diagnostic monitoring, we followed 100 consecutive eligible patients. Primary outcome was a composite of major vascular events within hospital, including myocardial infarction (defined as any troponin elevation associated with electrocardiographic changes suggesting ischemia, regardless of symptoms). Results: we included 534 clinical charts and 100 prospective surgical patients (mean age 62.2, SD 12.9 years; 56% women). The more frequent surgical procedures were orthopedics (26.8%) followed by abdominal (20.2%).The incidence of major vascular events recorded in clinical charts was 2.8%, compared with 7% among monitored patients (p=0,071). All four myocardial infarctions identified among the later group were silent. Conclusion: postoperative monitoring with troponin and electrocardiography identified a higher proportion of major vascular events, mainly silent myocardial infarctions.

    Intra-hospital transportation (IHT) might compromise patient safety because of different care settings and higher demand on the human operation. Reports regarding the incidence of IHT-related patient safety events and human failures remain limited. To perform a retrospective analysis of IHT-related events, human failures and unsafe acts. A hospital-wide process for the IHT and database from the incident reporting system in a medical centre in Taiwan. All eligible IHT-related patient safety events between January 2010 to December 2015 were included. Incidence rate of IHT-related patient safety events, human failure modes, and types of unsafe acts. There were 206 patient safety events in 2 009 013 IHT sessions (102.5 per 1 000 000 sessions). Most events (n=148, 71.8%) did not involve patient harm, and process events (n=146, 70.9%) were most common. Events at the location of arrival (n=101, 49.0%) were most frequent; this location accounted for 61.0% and 44.2% of events with patient harm and those without harm, respectively (pprocess step was the preparation of the transportation team (n=91, 48.9%). Contributing unsafe acts included perceptual errors (n=14, 7.5%), decision errors (n=56, 30.1%), skill-based errors (n=48, 25.8%), and non-compliance (n=68, 36.6%).

    Most patients with acute coronary syndrome (ACS) are treated with statins, which reduce atherogenic triglyceride-rich lipoproteins. It is uncertain whether triglycerides predict risk after ACS on a background of statin treatment. This study examined the relationship of fasting triglyceride levels to outcomes after ACS in patients treated with statins. Long-term and short-term relationships of triglycerides to risk after ACS were examined in the dal-OUTCOMES trial and atorvastatin arm of the MIRACL (Myocardial Ischemia Reduction with Acute Cholesterol Lowering) trial, respectively. Analysis of dal-OUTCOMES included 15,817 patients (97% statin-treated) randomly assigned 4 to 12 weeks after ACS to treatment with dalcetrapib (a cholesteryl ester transfer protein inhibitor) or placebo and followed for a median 31 months. Analysis of MIRACL included 1,501 patients treated with atorvastatin 80 mg daily beginning 1 to 4 days after ACS and followed for 16 weeks. Fasting triglycerides at initial random assignment were related to risk of coronary heart disease death, nonfatal myocardial infarction, stroke, and unstable angina in models adjusted for age, sex, hypertension, smoking, diabetes, high-density lipoprotein cholesterol, and body mass index. Fasting triglyceride levels were associated with both long-term and short-term risk after ACS. In dal-OUTCOMES, long-term risk increased across quintiles of baseline triglycerides (p175/≤80 mg/dl) was 1.61 (95% confidence interval: 1.34 to 1.94). There was no interaction of triglycerides and treatment assignment on the primary outcome. In the atorvastatin group of MIRACL, short-term risk increased across tertiles of baseline triglycerides (p=0.03), with a hazard ratio of 1.50 [corrected] (95% confidence interval: 1.05 to 2.15) in highest/lowest tertiles (>195/≤135 mg/dl). The relationship of triglycerides to risk was independent of low-density lipoprotein cholesterol in both studies. Among patients with ACS treated effectively

    Although preventive drug therapy is a priority after acute coronary syndrome, less is known about adherence to behavioral recommendations. The aim of this study was to examine the influence of adherence to behavioral recommendations in the short term on risk of cardiovascular events. The study population included 18 809 patients from 41 countries enrolled in the Organization to Assess Strategies in Acute Ischemic Syndromes (OASIS) 5 randomized clinical trial. At the 30-day follow-up, patients reported adherence to diet, physical activity, and smoking cessation. Cardiovascular events (myocardial infarction, stroke, cardiovascular death) and all-cause mortality were documented to 6 months. About one third of smokers persisted in smoking. Adherence to neither diet nor exercise recommendations was reported by 28.5%, adherence to either diet or exercise by 41.6%, and adherence to both by 29.9%. In contrast, 96.1% of subjects reported antiplatelet use, 78.9% reported statin use, and 72.4% reported angiotensin-converting enzyme/angiotensin receptor blocker use. Quitting smoking was associated with a decreased risk of myocardial infarction compared with persistent smoking (odds ratio, 0.57; 95% confidence interval, 0.36 to 0.89). Diet and exercise adherence was associated with a decreased risk of myocardial infarction compared with nonadherence (odds ratio, 0.52; 95% confidence interval, 0.4 to 0.69). Patients who reported persistent smoking and nonadherence to diet and exercise had a 3.8-fold (95% confidence interval, 2.5 to 5.9) increased risk of myocardial infarction/stroke/death compared with never smokers who modified diet and exercise. Adherence to behavioral advice (diet, exercise, and smoking cessation) after acute coronary syndrome was associated with a substantially lower risk of recurrent cardiovascular events. These findings suggest that behavioral modification should be given priority similar to other preventive medications immediately after acute coronary

    Crowd crushes with dozens or even hundreds of casualties have occurred several times at the Hajj in Saudi Arabia and also in soccer stadiums in Western Europe. As fatal accidents after human stampedes during mass events occur very rarely and are usually accompanied by many years of criminal court proceedings in order to identify underlying responsible mechanisms and culprits, it is very difficult to draw conclusions and formulate precautions from an emergency medical point of view. This study analyzed a fatal crowd crush which occurred on 4 December 1999 following the "Air & Style" snowboard contest with approximately 22,000 people attending in the Bergisel stadium in Innsbruck, Austria. Firstly, focused interviews were conducted with professional rescuers, police and physicians and secondly publicly available court records dealing with this incident in the district court of Innsbruck, Austria were analyzed. During the snowboard contest 87 emergency medical technicians, 6 emergency physicians, 1 leading emergency physician, 21 policemen and 140 security personnel were present. Following the accident additionally some 100 emergency medical technicians, 36 emergency medical service vehicles and 4 physician-staffed emergency medical service vehicles responded to the scene. The deadly crowd crush resulting in 6 fatalities, 4 patients still in a vegetative state and 38 injured, was due to a severe crowd accumulation at one stadium exit, which was not recognized and dispersed in time. Construction of the exit in line with darkness, steep slope and slippery surface contributed adversely to this dangerous situation, although panic did not occur at any time. Unfortunately, there is no patent remedy to completely prevent fatal accidents by a crowd crush at mass events. If planning is initiated early, sufficient material and personnel reserves are kept in reserve and despite conflicting interests of the organizers, the host community, security, police and emergency medical

    Hypoalbuminemia may increase the risk of acute kidney injury (AKI). The authors investigated whether the immediate preoperative administration of 20% albumin solution affects the incidence of AKI after off-pump coronary artery bypass surgery. In this prospective, single-center, randomized, parallel-arm double-blind trial, 220 patients with preoperative serum albumin levels less than 4.0 g/dl were administered 100, 200, or 300 ml of 20% human albumin according to the preoperative serum albumin level (3.5 to 3.9, 3.0 to 3.4, or less than 3.0 g/dl, respectively) or with an equal volume of saline before surgery. The primary outcome measure was AKI incidence after surgery. Postoperative AKI was defined by maximal AKI Network criteria based on creatinine changes. Patient characteristics and perioperative data except urine output during surgery were similar between the two groups studied, the albumin group and the control group. Urine output (median [interquartile range]) during surgery was higher in the albumin group (550 ml [315 to 980]) than in the control group (370 ml [230 to 670]; P = 0.006). The incidence of postoperative AKI in the albumin group was lower than that in the control group (14 [13.7%] vs. 26 [25.7%]; P = 0.048). There were no significant between-group differences in severe AKI, including renal replacement therapy, 30-day mortality, and other clinical outcomes. There were no significant adverse events. Administration of 20% exogenous albumin immediately before surgery increases urine output during surgery and reduces the risk of AKI after off-pump coronary artery bypass surgery in patients with a preoperative serum albumin level of less than 4.0 g/dl.

    Full Text Available Background: Information about post-acute coronary syndrome (ACS survival have been mostly short-term findings or based on specialized, cardiology referral centers. Objectives: To describe one-year case-fatality rates in the Strategy of Registry of Acute Coronary Syndrome (ERICO cohort, and to study baseline characteristics as predictors. Methods: We analyzed data from 964 ERICO participants enrolled from February 2009 to December 2012. We assessed vital status by telephone contact and official death certificate searches. The cause of death was determined according to the official death certificates. We used log-rank tests to compare the probabilities of survival across subgroups. We built crude and adjusted (for age, sex and ACS subtype Cox regression models to study if the ACS subtype or baseline characteristics were independent predictors of all-cause or cardiovascular mortality. Results: We identified 110 deaths in the cohort (case-fatality rate, 12.0%. Age [Hazard ratio (HR = 2.04 per 10 year increase; 95% confidence interval (95%CI = 1.75–2.38], non-ST elevation myocardial infarction (HR = 3.82 ; 95%CI = 2.21–6.60 or ST elevation myocardial infarction (HR = 2.59; 95%CI = 1.38–4.89 diagnoses, and diabetes (HR = 1.78; 95%CI = 1.20‑2.63 were significant risk factors for all-cause mortality in the adjusted models. We found similar results for cardiovascular mortality. A previous coronary artery disease diagnosis was also an independent predictor of all-cause mortality (HR = 1.61; 95%CI = 1.04–2.50, but not for cardiovascular mortality. Conclusion: We found an overall one-year mortality rate of 12.0% in a sample of post-ACS patients in a community, non-specialized hospital in São Paulo, Brazil. Age, ACS subtype, and diabetes were independent predictors of poor one‑year survival for overall and cardiovascular-related causes.

  13. EMIR: a configurable hierarchical system for event monitoring and incident response

    2014-07-01

    The Event Monitor and Incident Response system (emir) is a flexible, general-purpose system for monitoring and responding to all aspects of instrument, telescope, and general facility operations, and has been in use at the Automated Planet Finder telescope for two years. Responses to problems can include both passive actions (e.g. generating alerts) and active actions (e.g. modifying system settings). Emir includes a monitor-and-response daemon, plus graphical user interfaces and text-based clients that automatically configure themselves from data supplied at runtime by the daemon. The daemon is driven by a configuration file that describes each condition to be monitored, the actions to take when the condition is triggered, and how the conditions are aggregated into hierarchical groups of conditions. Emir has been implemented for the Keck Task Library (KTL) keyword-based systems used at Keck and Lick Observatories, but can be readily adapted to many event-driven architectures. This paper discusses the design and implementation of Emir , and the challenges in balancing the competing demands for simplicity, flexibility, power, and extensibility. Emir 's design lends itself well to multiple purposes, and in addition to its core monitor and response functions, it provides an effective framework for computing running statistics, aggregate values, and summary state values from the primitive state data generated by other subsystems, and even for creating quick-and-dirty control loops for simple systems.

    Red cell distribution width (RDW) has been found to be a novel prognostic biomarker in patients with coronary artery disease (CAD); however, the association between RDW and the risk of heart events in patients with CAD is yet to be fully elucidated. Thus, the aim of the present study was to determine whether an elevated RDW was associated with the Framingham risk score (FRS) in patients with CAD. Data were retrospectively collected from Affiliated Dongyang Hospital of Wenzhou Medical University (Dongyang, China). The patients had undergone a coronary angiography and their clinical data were integrated. The patients (male, 260; female, 132) were divided into two groups based on the results of the coronary angiography, namely the CAD (n=283) and control groups (n=109). The FRS was calculated for all the subjects, and complete blood count testing with biochemical measurements was performed. The mean RDW level was 13.7±1.8% in the CAD group and 13.1±1.0% in the control group, while the mean FRS was 9.0±4.9 in the CAD group and 6.4±3.9 in the control group. The RDW and FRS were significantly higher in the CAD group compared with the control group (P0.05). The RDW was shown to significantly correlate with the red blood cell (RBC) count ( r =-0.133, P=0.029), hemoglobin level ( r =-0.207, P=0.001) and TG level ( r =0.226, P<0.001) within the laboratory parameters, as well as the FRS ( r =0.206, P<0.001). In the stepwise multivariate linear regression, which included the RBC count, hemoglobin level, TG level and RDW, the FRS was predicted by hemoglobin ( r 2 =0.034, P=0.001), TG ( r 2 =0.059, P<0.001) and RDW ( r 2 =0.030, P=0.003) parameters. Therefore, a novel association was revealed between higher levels of RDW and an elevated FRS in patients with CAD, which raises the possibility that a simple marker, RDW, may be associated with an increased risk of heart events in CAD patients.

    Objective: To make a comprehensive evaluation of the efficacy and safety of different doses of clopidogrel that was used after percutaneous coronary intervention (PCI) in preventing the cardiovascular events in order to provide scientific basis for physician in making therapeutic strategic decision. Methods: The authors searched the electronic databases (PubMed, Cochrane Central Register of Controlled Trials, CNKI and Wan Fan) and reference lists from original studies and reviewed the related articles.Statistical analysis was performed by using RevMan 4.2 software. Results: A total of 6 studies containing 1027 patients were included. The results of meta-analysis showed that significant differences in the rate of cardiovascular events [OR = 0.52, 95%CI (0.36, 0.77)] existed between higher clopidogrel maintenance dose and standard dose. No obvious difference was found in major or minor bleeding [OR=1.25, 95%CI(0.43, 3.63)] and [OR = 1.25, 95%CI (0.77, 2.02)]. Conclusion: A higher maintenance dose of clopidogrel employed in patients undergoing PCI can reduce the occurrence of cardiovascular events after PCI without increasing the bleeding risk.

    The aim of this study was to identify aggressive event incidence rates in the inpatient psychiatric setting, describe characteristics of events and differences based on aggression target and type (verbal vs. physical). A longitudinal study was carried out of aggressive events identified by workers in four inpatient psychiatric units using the Staff Observation of Aggression Scale-Revised (SOAS-R) over 6 weeks. A total of 113 aggressive events were recorded resulting in a rate of 13.27 events per bed per year. Verbal aggression was demonstrated in 86 % and physical aggression in 57 % of events. Most events (70.8 %, n = 81) targeted a worker. Compared to other targets, workers were 3.4 times more likely to feel threatened (95 % CI 1.2-9.6, χ 2  = 5.08, p = 0.0242), and less likely to have a visible injury (OR 0.15, 95 % CI 0.04-0.6; χ 2  = 7.1, p = 0.0078). Event severity ranged from 0 to 21 with a mean of 9.5(SD = 5.1), with 20 % considered severe. Verbal events had lower mean severity of 6.5(SD = 3.8) versus physical events with a severity of 11.8(SD = 4.8; t = 6.5, df = 111, p Aggression incidence was similar to incidence found in other studies. Workers were the target of most aggressive events and many were identified as having no understandable provocation. Further understanding of event characteristics will promote more effective prevention and management of aggressive events.

    To investigate the progression of coronary atherosclerosis burden by coronary CT angiography (CCTA) and to demonstrate its association with the incidence of major adverse cardiac events (MACE). We retrospectively studied patients with stable angina who had undergone repeat CCTA due to recurrent or worsening symptoms. Lipid-rich, fibrous, calcified and total plaque burden as well as coronary diameter stenosis were quantitatively analysed. The incidence of MACE during follow-up was determined. The final cohort consisted of 268 patients (mean age 52.9 ± 9.8 years, 71 % male) with a mean follow-up period of 4.6 ± 0.9 years. Patients with lipid-rich, fibrous, calcified and total plaque burden (%) progression, as well as coronary diameter stenosis (%) progression had a significantly higher incidence of MACE than those without (all p < 0.05). The progression of lipid-rich plaque (HR = 1.601, p = 0.021), total plaque burden (HR = 2.979, p = 0.043) and coronary diameter stenosis (HR = 4.327, p <0.001) were independent predictors of MACE (all p < 0.05). Patients presenting with recurrent or worsening symptoms associated with coronary artery disease who have coronary atherosclerosis progression on CCTA are at an increased risk of future MACE.

    We investigated the association between income-education groups and incident coronary heart disease (CHD) in a national prospective cohort study. The REasons for Geographic And Racial Differences in Stroke study recruited 30,239 black and white community-dwelling adults between 2003 and 2007 and collected participant-reported and in-home physiologic variables at baseline, with expert adjudicated CHD endpoints during follow-up. Mutually exclusive income-education groups were: low income (annual household income events through December 31, 2011 (median follow-up 6.0 years; interquartile range 4.5-7.3 years). Those with low income/low education had the highest incidence of CHD (10.1 [95% CI 8.4-12.1]/1000 person-years). After full adjustment, those with low income/low education had higher risk of incident CHD (HR 1.42 [95% CI: 1.14-1.76]) than those with high income/high education, but findings varied by age. Among those aged independent effects of income and education are less pronounced.

    Hemodynamics has a key role in atheropathogenesis. Indeed, atherosclerotic phenomena occur in vessels characterized by complex geometry and flow pattern, like the carotid bifurcation. Moreover, lifestyle is a significant risk factor. The aim of this study is to evaluate the hemodynamic effects due to two sedentary lifestyles - sitting and standing positions - in the carotid bifurcation in order to identify the worst condition and to investigate the atherosclerosis incidence. The computational fluid dynamics (CFD) was chosen to carry out the analysis, in which in vivo non-invasive measurements were used as boundary conditions. Furthermore, to compare the two conditions, one patient-specific 3D model of a carotid bifurcation was reconstructed starting from computer tomography. Different mechanical indicators, correlated with atherosclerosis incidence, were calculated in addition to flow pattern and pressure distribution: the time average wall shear stress (TAWSS), the oscillatory shear index (OSI) and the relative residence time (RRT). The results showed that the bulb and the external carotid artery emergence are the most probable regions in which atherosclerotic events could happen. Indeed, low velocity and WSS values, high OSI and, as a consequence, areas with chaotic-swirling flow, with stasis (high RRT), occur. Moreover, the sitting position is the worst condition: considering a cardiac cycle, TAWSS is less than 17.2% and OSI and RRT are greater than 17.5% and 21.2%, respectively. This study suggests that if a person spends much time in the sitting position, a high risk of plaque formation and, consequently, of stenosis could happen.

    Background Denosumab therapy is commonly used for the prevention of skeletal-related events in patients with bone metastasis. However, a common side effect of denosumab is hypocalcemia. Objective The aim of the study is to determine the incidence of hypocalcemia in patients receiving denosumab for prevention of skeletal-related events in bone metastasis and evaluate risk factors for developing hypocalcemia. Methods This was a retrospective medication use evaluation reviewing the incidence of hypocalcemia in patients receiving outpatient denosumab for prevention of skeletal-related events at Yale-New Haven Hospital. Additionally, various risk factors were reviewed to determine their risk of developing hypocalcemia. Results As per Common Terminology Criteria for Adverse Events v4.03, of the 106 patients included in the study population, 37 (35%) patients had an incidence of hypocalcemia within 30 days of denosumab administration. Fourteen patients (13.2%) had an incidence of grade 1, 13 patients (12.3%) had an incidence of grade 2 hypocalcemia, and 7 patients (6.6%) had an incidence of grade 3 hypocalcemia. Grade 4 hypocalcemia occurred in three (2.8%) patients. Calcium supplementation did not decrease the risk of developing hypocalcemia. Patients who had one or more episodes of acute kidney insufficiency were at a higher risk of developing hypocalcemia (odds ratio = 7.5 (95% confidence interval = 1.8-36.3), p = 0.001). Conclusion This study found that the overall incidence of hypocalcemia and severe hypocalcemia was higher than reported in clinical trials. Additionally, calcium supplementation did not have an effect on incidence of hypocalcemia, while patients who experienced acute kidney insufficiency while on denosumab had a higher likelihood of developing hypocalcemia.

  9. New treatment of low probability events with particular application to nuclear power plant incidents

    The 'New Treatment' attempts to resolve the 'Zero-Infinity Dilemmas' posed by the threat of low probability events (LPE) philosophical approach which rejects mathematical idealism in favour of the engineering pragmatism that is characteristic of the scientific method. The LPE is seen as a rare singularity in the stream of 'Event-noise' of mundane, untoward incidents that afflict industrial systems. Engineering inspection which has evolved as a regulatory mechanism can be effective in reducing this 'noise' and the competent inspector is able to recognise the 'loss of resistance to failure' which so often comes before an LPE. Despite that an intractable residual risk remains, but this can be made societally tolerable if there is a justifiable conviction that safety is defended by trustworthy engineering. In an age marked by an increasing complexity and sophistication in its science and technology, the engineer is emerging as the proper central decision maker in such matters standing, athwart pure administration and theory on the one hand and expertise and practice on the other. Moreover, evidence that his intellect may be peculiarly adapted for such a role is coming from recent findings in neuropsychology. The Nuclear Installations Inspectorate is cited as an exemplar of the engineering inspection needed to apprehend those human fallibilities in design and application to which most catastrophic failures of technology are due. However, such regulatory systems and the assessment functions associated with them lack accountability and, as an interpretation of Goedel's theorem suggests, cannot assess their own efficiency. Independent, disinterested appraisal assisted by Signal Detection Theory is offered as a remedy.

    The metabolic syndrome defined by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) is a predictor of cardiovascular events. However, the significance of metabolic syndrome for cardiovascular events has been not clarified in Japan. The impact of metabolic syndrome and diabetes mellitus on cardiovascular events was investigated, especially in the high risk group after percutaneous coronary intervention. We studied 456 patients (mean age 63±10 years, range 36-88 years) without ischemia on stress thallium-201 single photon emission computed tomography after percutaneous coronary intervention. The diagnosis of metabolic syndrome was made according to the modified NCEP ATP III criteria. Cardiovascular events were examined for mean 3.7±1.8 years (range 2.0-8.7 years). There were 196 patients without diabetes mellitus or metabolic syndrome (Group D-M-), 89 patients without diabetes mellitus but with metabolic syndrome (Group D-M+), 61 patients with diabetes mellitus but without metabolic syndrome (Group D+M-), and 110 patients with both diabetes mellitus and metabolic syndrome (Group D+M+). The event-free survival curve in Group D-M+ was significantly lower than that in Group D-M- (p<0.05), but not different from that in Group D+M-. The survival curve was markedly lower in Group D+M+ than that in Group D-M+ (p<0.005). The Cox proportional hazard model revealed that diabetes mellitus and metabolic syndrome were independent significant risk factors for events. The diagnosis of metabolic syndrome was helpful for identification of patients with high cardiovascular event rate even in patients after percutaneous coronary intervention. The combination of metabolic syndrome and diabetes mellitus markedly increases the risk for cardiovascular events. (author)

    Obtaining serum troponin levels in every patient with acute stroke is recommended in recent stroke guidelines, but there is no evidence that these contribute positively to clinical care. We sought to determine the clinical significance of measuring troponin levels in acute ischemic stroke patients. We reviewed 398 consecutive patients with acute ischemic stroke at a large academic institution from 2010 to 2012. Troponin levels were measured as a result of protocol in place during part of the study period. The mean age was 70 years (standard deviation ±16 years) and 197 (49.5%) were men. Chronic kidney disease was present in 78 (19.6%), coronary artery disease in 107 (26.9%), and atrial fibrillation in 107 (26.9%). Serum troponin T was measured in 246 of 398 patients (61.8%). Troponin was elevated (>.01 ng/mL) at any point in 38 of 246 patients (15.5%) and was elevated in 28 patients at all 3 measurements (11.3% of those with troponin measured). Only 4 of 246 patients (1.6%) had a significant uptrend. Two were iatrogenic in the setting of hemodynamic augmentation using vasopressors to maintain cerebral perfusion. One case was attributed to stroke and chronic kidney disease and another case to heart failure from inflammatory fibrocalcific mitral valvular heart disease. Serum troponin elevation in patients with ischemic stroke is not usually caused by clinically significant acute myocardial ischemia unless iatrogenic in the setting of vasopressor administration. Serum troponin levels should be measured judicially, based on clinical context, rather than routinely in all stroke patients. Copyright © 2016 National Stroke Association. Published by Elsevier Inc.

    Women with acute coronary syndromes have lower rates of cardiac catheterization (CC) than men. To determine whether sex⁄gender, age, risk level and patient preference influence physician decision making to refer patients for CC. Twelve clinical scenarios controlling for sex⁄gender, age (55 or 75 years of age), Thrombolysis in Myocardial Infarction risk score (low, moderate or high) and patient preference for CC (agreeable or refused⁄no preference expressed) were designed. Scenarios were administered to specialists across Canada using a web-based computerized survey instrument. Questions were standardized using a five-point Likert scale ranging from 1 (very unlikely to benefit from CC) to 5 (very likely to benefit from CC). Outcomes were assessed using a two-tailed mixed linear regression model. Of 237 scenarios, physicians rated men as more likely to benefit from CC than women (mean [± SE] 4.44±0.07 versus 4.25±0.07, P=0.03), adjusted for age, risk and patient preference. Low-risk men were perceived to benefit more than low-risk women (4.20±0.13 versus 3.54±0.14, Pno comment at all (5.0±0.23, 3.67±0.21, 2.95±0.14, respectively, P<0.01). Canadian specialists' decisions to refer patients for CC appear to be influenced by sex⁄gender, age and patient preference in clinical scenarios in which cardiac risk is held constant. Future investigation of possible age and sex⁄gender biases as proxies for risk is warranted.

    Conventional cardiovascular risk estimators based on clinical demographics have limited prediction of coronary events. Markers for thrombogenicity and vascular function have not been explored in risk estimation of high-risk patients with coronary artery disease. We aimed to develop a clinical and biomarker score to predict 3-year adverse cardiovascular events. Four hundred eleven patients, with ejection fraction ≥40% undergoing coronary angiography, and found to have a luminal diameter stenosis ≥50%, were included in the analysis. Thrombelastography indices and central pulse pressure (CPP) were determined at the time of catheterization. We identified predictors of death, myocardial infarction (MI) or stroke and developed a numerical ischemia risk score. The primary endpoint of cardiovascular death, MI or stroke occurred in 22 patients (5.4%). The factors associated with events were age, prior PCI or CABG, diabetes, CPP, and thrombin-induced platelet-fibrin clot strength, and were included in the MAGMA-ischemia score. The MAGMA-ischemia score showed a c-statistic of 0.85 (95% Confidence Interval [CI] 0.80-0.87; pMAGMA-ischemia score greater than 5 had highest risk to develop clinical events, hazard ratio for the primary endpoint: 13.9 (95% CI 5.8-33.1, pMAGMA-ischemia score yielded a higher discrimination. Inclusion of CPP and assessment of thrombogenicity in a novel score for patients with documented CAD enhanced the prediction of events. Copyright © 2017 Elsevier B.V. All rights reserved.

    To evaluate the usefulness of systematic coronary angiography followed, if needed, by coronary artery angioplasty (percutaneous coronary intervention (PCI)) on the incidence of cardiac ischaemic events after carotid endarterectomy (CEA) in patients without evidence of coronary artery disease (CAD). From January 2005 to December 2008, 426 patients, candidates for CEA, with no history of CAD and with normal cardiac ultrasound and electrocardiography (ECG), were randomised into two groups. In group A (n=216) all the patients had coronary angiography performed before CEA. In group B, all the patients had CEA without previous coronary angiography. In group A, 66 patients presenting significant coronary artery lesions at angiography received PCI before CEA. They subsequently underwent surgery under aspirin (100 mg day(-1)) and clopidogrel (75 mg day(-1)). CEA was performed within a median delay of 4 days after PCI (range: 1-8 days). Risk factors, indications for CEA and surgical techniques were comparable in both groups (p>0.05). The primary combined endpoint of the study was the incidence of postoperative myocardial ischaemic events combined with the incidence of complications of coronary angiography. Secondary endpoints were death and stroke rates after CEA and incidence of cervical haematoma. Postoperative mortality was 0% in group A and 0.9% in group B (p=0.24). One postoperative stroke (0.5%) occurred in group A, and two (0.9%) in group B (p=0.62). No postoperative myocardial event was observed in group A, whereas nine ischaemic events were observed in group B, including one fatal myocardial infarction (p=0.01). Binary logistic regression analysis demonstrated that preoperative coronary angiography was the only independent variable that predicted the occurrence of postoperative coronary ischaemia after CEA. The odds ratio for coronary angiography (group A) indicated that when holding all other variables constant, a patient having preoperative coronary angiography

    Full Text Available Abstract Background In deciding where to undergo coronary-artery bypass grafting, the length of surgical wait lists is often the only information available to cardiologists and their patients. Our objective was to compare the cumulative incidence for death on the wait list according to the length of wait lists at the time of registration for the operation. Methods The study cohort included 8966 patients who registered to undergo isolated coronary-artery bypass grafting (82.4% men; 71.9% semi-urgent; 22.4% non-urgent. The patients were categorized according to wait-list clearance time at registration: either "1 month or less" or "more than 1 month". Cumulative incidence for wait-list death was compared between the groups, and the significance of difference was tested by means of regression models. Results Urgent patients never registered on a wait list with a clearance time of more than 1 month. Semi-urgent patients registered on shorter wait lists more often than non-urgent patients (79.1% vs. 44.7%. In semi-urgent and non-urgent patients, the observed proportion of wait-list deaths by 52 weeks was lower in category "1 month or less" than in category "more than 1 month" (0.8% [49 deaths] vs. 1.6% [39 deaths], P P Conclusion Long wait lists for coronary-artery bypass grafting are associated with increased probability that a patient dies before surgery. Physicians who advise patients where to undergo cardiac revascularization should consider the risk of pre-surgical death that is associated with the length of a surgical wait list.

    Objective: To investigate the correlation between recent cardiac events and the score of myocardial infarction by delayed-enhancement MRI (DE-MRI). Methods: DE-MRI was performed in 40 subjects with coronary artery disease. The score of myocardial infarction by DE-MRI, the ejection fraction (EF) by echocardiography, recent cardiac events (the number of weekly nitroglycerin, the number of weekly angina episodes and the onset number of heart failure in the last year), 6-minute walking distance, as well as the Seattle angina questionnaire (SAQ) score were assessed. The Spearman correlation test and Kruskal-Wallis test, Mann-Whitney test were used for the statistics. Results: There were negative correlation between the myocardial infarction score by DE-MRI (median 12, inter-quartile range: 6.0-19.8) and the 6-minute walking distance (378.93±100.53), SAQ score (74.55±11.40) (r was 0.66 and 0.54, P< 0.05). The myocardial infarction score by DE-MRI was strongly correlated with the number of weekly nitroglycerin (median 1; inter-quartile range: 0-2.8), the number of weekly angina episodes (median 3, inter-quartile range: 1-6.5) and the onset number of heart failure in the last year (median 0, inter-quartile range: 0-2) (r was 0.87, 0.85 and 0.89, P<0.05). EF [(49.2±13.72)%] was negative correlation with the number of weekly nitroglycerin, the number of weekly angina episodes and the onset number of heart failure in the last year (r were 0.67, 0.73 and 0.73, P<0.05). Conclusion: DE-MRI can be used for evaluation and prediction of future cardiac events. (authors)

    To determine the net economic impact of switching from low-osmolar contrast media (LOCM) to iso-osmolar contrast media (IOCM; iodixanol) in patients undergoing inpatient coronary or peripheral angioplasty in the United States (US). A budget impact model (BIM) was developed from a hospital perspective. Nationally representative procedural and contrast media prevalence rates, along with MARCE (major adverse renal cardiovascular event) incidence and episode-related cost data were derived from Premier Hospital Data (October 2014 to September 2015). A previously estimated relative risk reduction in MARCE associated with IOCM usage (9.3%) was applied. The higher cost of IOCM was included when calculating the net impact estimates at the aggregate, hospital type, and per hospital levels. One-way (±25%) and probabilistic sensitivity analyses identified the model's most important inputs. Based on weighted analysis, 513,882 US inpatient angioplasties and 35,610 MARCE cases were estimated annually. Switching to an "IOCM only" strategy from a "LOCM only" strategy increases contrast media cost, but prevents 2,900 MARCE events. The annual budget impact was an estimated saving of $30.71 million, aggregated across all US hospitals, $6,316 per hospital, or $60 per procedure. Net savings were maintained across all univariate sensitivity analyses. While MARCE/event-free cost differential was the most important factor driving total net savings for hospitals in the Northeast and West, procedural volume was important in the Midwest and rural locations. Switching to an "IOCM only" strategy from a "LOCM only" approach yields substantial net global savings to hospitals, both at the national level and within hospital sub-groups. Hospital administrators should maintain awareness of the factors that are likely to be more influential for their hospital and recognize that purchasing on the basis of lower contrast media cost may result in higher overall costs for patients undergoing inpatient

    The use of bivalirudin versus unfractionated heparin monotherapy in patients without ST-segment-elevation myocardial infarction is not well defined. The study population consisted of patients enrolled in the Evaluation of Drug-Eluting Stents and Ischemic Events (EVENT) registry with either non-ST-segment-elevation acute coronary syndromes or stable ischemic heart disease, who underwent percutaneous coronary intervention with either unfractionated heparin or bivalirudin monotherapy. Propensity score matching was used to adjust for baseline characteristics. The primary bleeding (in-hospital composite bleeding-access site bleeding, thrombolysis in myocardial infarction major/minor bleeding, or transfusion) and primary (in-hospital death/myocardial infarction) and secondary ischemic outcomes (death/myocardial infarction/unplanned repeat revascularization at 12 months) were evaluated. Propensity score matching yielded 1036 patients with non-ST-segment-elevation acute coronary syndromes and 2062 patients with stable ischemic heart disease. For the non-ST-segment-elevation acute coronary syndrome cohort, bivalirudin use was associated with lower bleeding (difference, -3.3% [-0.8% to -5.8%]; P=0.01; number need to treat=30) without increase in either primary (difference, 1.2% [4.1% to -1.8%]; P=0.45) or secondary ischemic outcomes, including stent thrombosis (difference, 0.0% [1.3% to -1.3%]; P=1.00). Similarly, in the stable ischemic heart disease cohort, bivalirudin use was associated with lower bleeding (difference, -1.8% [-0.4% to -3.3%]; P=0.01; number need to treat=53) without increase in either primary (difference, 0.4% [2.3% to -1.5%]; P=0.70) or secondary ischemic outcomes, including stent thrombosis (difference, 0.0% [0.7% to -0.7%]; P=1.00) when compared with unfractionated heparin monotherapy. Among patients with non-ST-segment-elevation acute coronary syndromes or stable ischemic heart disease undergoing percutaneous coronary intervention, bivalirudin use

    To identify the incidence and timing of venous thromboembolism as well as any associated risk factors in patients with ovarian, fallopian tube, or primary peritoneal cancer undergoing neoadjuvant chemotherapy. We conducted a retrospective cohort study of patients diagnosed with ovarian, fallopian tube, and primary peritoneal cancer and receiving neoadjuvant chemotherapy from January 2009 to May 2014 at a single academic institution. The timing and number of venous thromboembolic events for the entire cohort were categorized as follows: presenting symptom, during neoadjuvant chemotherapy treatment, after debulking surgery, and during adjuvant chemotherapy. Of the 125 total patients with ovarian cancer undergoing neoadjuvant chemotherapy, 13 of 125 patients (10.4%, 95% confidence interval [CI] 6.1-17.2%) had a venous thromboembolism as a presenting symptom and were excluded from further analysis. Of the 112 total patients at risk, 30 (26.8%, 95% CI 19.3-35.9%) experienced a venous thromboembolism. Based on the phase of care, 13 (11.6%, 95% CI 6.8-19.1%) experienced a venous thromboembolism during neoadjuvant chemotherapy, six (5.4%, 95% CI 2.4-11.5%) developed a postoperative venous thromboembolism, and 11 (9.9%, 95% CI 5.5-17%) developed a venous thromboembolism during adjuvant chemotherapy. Two of the four patients with clear cell histology developed a venous thromboembolism in this cohort. Overall new diagnosis of venous thromboembolism was associated with one fourth of the patients undergoing neoadjuvant chemotherapy for ovarian cancer with nearly half of these diagnosed during chemotherapy cycles before interval debulking surgery. Efforts to reduce venous thromboembolism so far have largely focused on the postoperative period. Additional attention to venous thromboembolic prophylaxis during chemotherapy (neoadjuvant and adjuvant) in this patient population is warranted in an effort to decrease the rates of venous thromboembolism.

    Full Text Available Background: The identification of coronary artery calcification (CAC detected coincidentally on chest CT exams could assist in cardiovascular risk assessment but may not be reported consistently on clinical studies. Cardiovascular risk factor stratification is important to predict short term cardiac events during cancer therapy and long term cardiac event free survival in cancer patients. We sought to determine the prevalence of CAC and clinical reporting rates in a cohort of cancer patients at high risk of cancer therapy related cardiac events. Methods: 408 Breast cancer patients who were referred to a cardiac oncology clinic were screened. Inclusion criteria included having had a CT chest and the absence of known coronary disease. Among those screened 263 patients were included in the study. Results: CAC was identified in 70 patients (26%. CAC was reported in 18% of studies. The reporting rates of CAC increased with the extent of coronary calcification (p < 0.01 and increased during the period of the study (p < 0.05. Conclusions: CAC was commonly detected on chest CT studies in this observational study of breast cancer patients at high risk of cardiac oncology events. The presence of CAC was often not reported clinically but reporting rates have increased over time. Recent SCCT/STR guidelines recommend reporting the presence of CAC on routine chest CT scans in recognition of the importance of CAC as a predictor of cardiovascular events. Reporting of CAC on chest CTs may help to further risk stratify breast cancer patients and improve cardiovascular outcomes in this vulnerable population.

    Contrast-induced acute kidney injury (CI-AKI) is associated with poor outcome. Whether this association differs in stable coronary artery disease (CAD) as compared to acute coronary syndrome (ACS) patients is unknown. Definitions and Methods: PRODIGY trial patients were defined as stable CAD or ACS according to the initial presentation. CI-AKI was defined as an increase (Δ) of serum creatinine (SCr) ≥25% above baseline. Two endpoints were considered: all-cause death and the composite of death, stroke, or myocardial infarction (MI). The interaction between CI-AKI, clinical setting, and the impact of increasing ΔSCr% cut-offs were also explored. Two thousand three patients were enrolled in the PRODIGY trial, 85 patients were excluded for missing SCr data, leading to a population of 1,918 patients. CI-AKI incidence was 6.7% in stable CAD and 12.2% in ACS patients. CI-AKI was associated with all-cause mortality [adjusted hazard ratio (aHR) of 2.05, 95% confidence interval (CI) 1.38-3.05, P  0.001]. In a large, contemporary, all-comers percutaneous coronary intervention population, CI-AKI was associated with an increased risk of all-cause death and the composite of death, stroke, or MI. While CI-AKI is more common in ACS than in stable CAD patients, its adjusted prognostic impact on the composite endpoint appears to be more pronounced in patients with stable CAD. © 2015 Wiley Periodicals, Inc.

    Full Text Available The role of fasting glucose, insulin levels, and C-peptide in coronary heart disease (CHD in non-diabetic individuals remains uncertain. We examined the association between fasting glucose, insulin and C-peptide with the long-term incidence of CHD in Japanese-American men. In 1980–1982, from a random sample of the Honolulu Heart Program men (n = 1378, aged 61–81 years, data on several CHD and metabolic risk factors were obtained to examine the relation of fasting glucose, insulin and C-peptide to 19-year CHD incidence. Age-adjusted incidence of CHD increased with increasing quintiles of glucose, insulin and C-peptide. Age-adjusted CHD rates in the glucose quintiles were 11.9, 11.6, 14.4, 18.1 and 24.1 per 1000 person-years (trend p < 0.001. In individual Cox models (lowest quintiles of glucose, insulin and C-peptide as reference the relative risks (95% confidence interval of CHD incidence for the glucose quintiles adjusting for age, smoking, hypertension, cholesterol, physical activity, and body mass index, were 0.9 (0.6–1.4, 1.2 (0.8–1.8, 1.4 (0.9–2.2, and 1.7 (1.1–2.6, respectively (trend p = 0.004. Insulin and C-peptide were not significantly associated with CHD on multivariate analysis. Fasting glucose remained the only significant predictor of increased CHD risk (p = 0.003 in a model combining all 3 metabolic variables. In this cohort, only fasting glucose independently predicts long-term incidence of CHD. Age-adjusted insulin and C-peptide levels were associated with CHD incidence, but after adjustment for other risk factors, do not independently predict CHD.

    Drug-eluting stents (DES) constitute a major achievement in preventing re-stenosis, concerns remain regarding the increased inflammatory responses associated with the polymers used. This analysis focuses on outcomes in patients receiving the polymer-free sirolimus-eluting stent system YUKON-Choice (Yukon-DES, Translumina, Germany). From 01/2006-09/2008 all patients receiving Yukon-DES (≥2.5 mm diameter) were prospectively enrolled in our registry. The primary endpoint was long-term major adverse cardiac events (MACE). 701 patients were included in our registry. Mean age was 65.7 ± 10 years (73% male gender, 35.5% diabetes, and 32.2% acute coronary syndrome). 76% of the lesions were of Type B2/C. Lesion length was 24.6 ± 5.2 mm and mean stent diameter was 2.8 ± 0.4 mm. A total of 511 pts (72%) underwent 6-months angiographic follow-up, target vessel revascularization was noted in 23.5%. At 5 years clinical outcomes were: cardiac death 5.8%; myocardial infarction 3.4%; and TVR 24.6%. The incidence of MACE differed significantly between "on-label" and "off-label" indications (14.8% vs. 40.8% MACE; P 1 year) ST occurred in 0.29%. Our data suggests that the implantation of the sirolimus-coated polymer-free YUKON-DES is safe and feasible with a very low incidence of ST in this real world patient cohort with high percentage of diabetes and small vessels. © 2013 Wiley Periodicals, Inc.

    Although serious complications during pediatric anesthesia are less common than they were 20 years ago, serious airway events continue to occur. Based on Quality Improvement (QI) data from our institution, a QI project was designed to reduce the incidence of serious airway events and airway cardiac arrests. A quality improvement team consisting of members of the Department of Anesthesia was formed and QI data from previous years were analyzed. The QI team developed a Smart Aim, Key Driver Diagram, and specific Interventions that focused on the accessibility of emergency drugs, the use of nondepolarizing muscle relaxants for endotracheal intubation in children 2 years and younger, and the presence of anesthesia providers until emergence from anesthesia in high-risk patients. The percentage of cases where muscle relaxants were utilized in children 2 years and younger for endotracheal intubation and where atropine and succinylcholine were readily available increased at both our base and outpatient facilities. Over the 2.5-year study period, the incidence of serious airway events and airway cardiac arrests was reduced by 44% and 59%, respectively compared to the previous 2-year period. We utilized QI methodology to design and implement a project which led to greater standardization of clinical practice within a large pediatric anesthesia group. Based on an understanding of system issues impacting our clinical practice, we designed and tested interventions that led to a significant reduction in the incidence of serious airway events and airway cardiac arrests. © 2015 John Wiley & Sons Ltd.

    The JUPITER trial showed that some patients with LDL-cholesterol concentrations less than 3·37 mmol/L (JUPITER, we established whether coronary artery calcium (CAC) might further stratify risk; additionally we compared hsCRP with CAC for risk prediction across the range of low and high hsCRP values. 950 participants from the Multi-Ethnic Study of Atheroslcerosis (MESA) met all criteria for JUPITER entry. We compared coronary heart disease and cardiovascular disease event rates and multivariable-adjusted hazard ratios after stratifying by burden of CAC (scores of 0, 1-100, or >100). We calculated 5-year number needed to treat (NNT) by applying the benefit recorded in JUPITER to the event rates within each CAC strata. Median follow-up was 5·8 years (IQR 5·7-5·9). 444 (47%) patients in the MESA JUPITER population had CAC scores of 0 and, in this group, rates of coronary heart disease events were 0·8 per 1000 person-years. 74% of all coronary events were in the 239 (25%) of participants with CAC scores of more than 100 (20·2 per 1000 person-years). For coronary heart disease, the predicted 5-year NNT was 549 for CAC score 0, 94 for scores 1-100, and 24 for scores greater than 100. For cardiovascular disease, the NNT was 124, 54, and 19. In the total study population, presence of CAC was associated with a hazard ratio of 4·29 (95% CI 1·99-9·25) for coronary heart disease, and of 2·57 (1·48-4·48) for cardiovascular disease. hsCRP was not associated with either disease after multivariable adjustment. CAC seems to further stratify risk in patients eligible for JUPITER, and could be used to target subgroups of patients who are expected to derive the most, and the least, absolute benefit from statin treatment. Focusing of treatment on the subset of individuals with measurable atherosclerosis could allow for more appropriate allocation of resources.

    Increasing global migration has made immigrants' health an important topic worldwide. We examined the effect of country of birth, migrant status (refugee/family-reunified) and income on coronary heart disease (CHD) incidence. This was a historical prospective register-based cohort study. The study cohort consisted of immigrants above 18 years from non-Western countries who had obtained a residence permit in Denmark as a refugee (n = 29,045) or as a family-reunified immigrant (n = 28,435) from 1 January 1993-31 December 1999 and a Danish-born reference population (n = 229,918). First-time CHD incidence was identified from 1 January 1993-31 December 2007. Incidence ratios for 11 immigrant groups were estimated using Cox regression analysis. Immigrants from Afghanistan, Iraq, Turkey, Eastern Europe and Central Asia, South Asia, the Former Yugoslavia, and the Middle East and North Africa had significantly higher incidences of CHD (hazard ratio (HR) = 1.36; 95% confidence interval (CI): 1.05-1.75 to HR = 2.86; 95% CI: 2.01-4.08) compared with Danish-born people. Immigrants from Somalia, South and Middle America, Sub-Saharan Africa and women from East Asia and the Pacific did not differ significantly from Danish-born people, whereas immigrant men from East Asia and the Pacific had a significantly lower incidence (HR = 0.32; 95% CI: 0.17-0.62). When also including migrant status, the higher incidences were reduced. Refugee men (HR = 1.35; 95% CI: 1.11-1.65) and women (HR = 1.33; 95% CI: 1.08-1.65) had a significantly higher incidence of CHD than family-reunified immigrants. When migrant status and income were included simultaneously, the incidences decreased to an insignificant level for most immigrant groups. Most non-Western immigrant groups had a higher incidence of CHD than Danish-born people. The study revealed that migrant status and income are important underlying mechanisms of the effect of country of birth on CHD. © The European

    We explored the impact of glycemic variability on the occurrence of periprocedural myocardial infarction and major adverse cardiovascular events (MACE) after coronary intervention in patients with stable angina pectoris (SAP) at 6months follow-up. From May 2015 to April 2016, a total of 746 patients with SAP were divided to high glycemic variability group (H group) (n=261) and low glycemic variability group (L group) (n=485). The primary end point was incidence of periprocedural myocardial infarction and MACE at 6months follow-up. The occurrence of periprocedural myocardial infarction occurred in 18.8% of patients in H group and in 12.4% in L group (P=0.03). The incidence of MACE at 6months follow-up was 9.6% in H group and 4.5% in L group (P=0.01). Multivariable analysis suggested that high glycemic variability conferred a 53% risk increment of 6months follow-up MACE (odds ratio 2.13, 95% confidence interval 1.85-5.38; P=0.01). The trial shows that higher blood glucose variability was correlated with higher incidence of periprocedural myocardial infarction and MACE at 6months follow-up. Copyright © 2017.

    It is unclear whether lifestyle changes can delay the need for surgical procedures in coronary heart disease (CHD) patients with asymptomatic reduced left ventricular ejection fraction (LVEF). The aim of this pilot study was to examine whether lifestyle changes can delay the need for surgical procedures in this population. We compared 3-year clinical events in 27 CHD patients eligible to receive revascularization (by insurance standards), but underwent lifestyle changes (low-fat diet, exercise, stress management) instead (intervention group [IG], LVEF Lifestyle Demonstration Project, an insurance-sponsored, community-based, secondary prevention study implemented at 8 hospital sites in the United States. At 3 months, there were more cardiac events in the UCG (6 events) than in the IG (1 event; P changes in lifestyle with no increased risk for cardiac events or overt heart failure over 3 years.

    Despite improvements in percutaneous coronary intervention (PCI), intraprocedural thrombotic events (IPTE) and bleeding complications occur and are prognostically important. These have not been included in prior economic studies. PHOENIX ECONOMICS was a substudy of the CHAMPION PHOENIX trial, evaluating cangrelor during PCI. Hospital bills were reviewed from 1,171 patients enrolled at 22 of 63 US sites. Costs were estimated using standard methods including resource-based accounting, hospital billing data, and the Medicare fee schedule. Bleeding and IPTE, defined as abrupt vessel closure (transient or sustained), new/suspected thrombus, new clot on wire/catheter, no reflow, side-branch occlusion, procedural stent thrombosis or urgent need for CABG were identified. Costs were calculated according to whether a complication occurred and type of event. Multivariate analyses were used to estimate the incremental costs of IPTE and postprocedural events. IPTE occurred in 4.3% and were associated with higher catheterization laboratory and overall index hospitalization costs by $2,734 (95%CI $1,117, $4,351; P = 0.001) and $6,354 (95% CI $4,122, $8,586; P < 0.001), respectively. IPTE were associated with MI (35.4% vs. 3.6%; P < 0.001), out-of-laboratory stent thrombosis (4.2% vs. 0.1%; 0 = 0.005), ischemia driven revascularization (12.5% vs. 0.3%; P < 0.001), but not mortality (2.1% vs. 0.2%; P = 0.12) vs. no procedural thrombotic complication. By comparison, ACUITY minor bleeding increased hospitalization cost by $1,416 (95%CI = 312, $2,519; P = 0.012). ACUITY major bleeding increased cost of hospitalization by $7,894 (95%CI $4,154, $11,635; P < 0.001). IPTE and bleeding complications, though infrequent, are associated with substantial increased cost. These complications should be collected in economic assessments of PCI. © 2018 Wiley Periodicals, Inc.

    Recent studies have demonstrated that aldosterone levels measured in patients with heart failure or acute myocardial infarction (MI) are associated with long-term mortality, but the association with aldosterone levels in patients with coronary artery disease (CAD) outside these specific settings remains unknown. In addition, no clear mechanism has been elucidated to explain these observations. The present study was designed to evaluate the relationship between the level of aldosterone and the risk of death and acute ischaemic events in CAD patients with a preserved left ventricular (LV) function and no acute MI. In 799 consecutive CAD patients referred for elective coronary angioplasty measurements were obtained before the procedure for: aldosterone (median = 25 pg/mL), brain natriuretic peptide (BNP) (median = 35 pg/mL), hsC-reactive protein (median = 4.17 mg/L), and left ventricular ejection fraction (mean = 58%). Patients with acute MI or coronary syndrome (ACS) who required urgent revascularization were not included in the study. The primary endpoint, cardiovascular death, occurred in 41 patients during a median follow-up period of 14.9 months. Secondary endpoints-total mortality, acute ischaemic events (acute MI or ischaemic stroke), and the composite of death and acute ischaemic events-were observed in 52, 54, and 94 patients, respectively. Plasma aldosterone was found to be related to BMI, hypertension and NYHA class, and inversely related to age, creatinine clearance, and use of beta-blockers. Multivariate Cox model analysis demonstrated that aldosterone was independently associated with cardiovascular mortality (P = 0.001), total mortality (P = 0.001), acute ischaemic events (P = 0.01), and the composite of death and acute ischaemic events (P = 0.004). Reclassification analysis, using integrated discrimination improvement (IDI) and net reclassification improvement (NRI), demonstrated incremental predictive value of aldosterone (P acute MI, the level of

    To compare the prognostic performance of three major risk scoring systems including global registry for acute coronary events (GRACE), thrombolysis in myocardial infarction (TIMI), and prediction of 30-day major adverse cardiovascular events after primary percutaneous coronary intervention (RISK-PCI). This single-center retrospective study involved 200 patients with acute coronary syndrome (ACS) who underwent invasive diagnostic approach, ie, coronary angiography and myocardial revascularization if appropriate, in the period from January 2014 to July 2014. The GRACE, TIMI, and RISK-PCI risk scores were compared for their predictive ability. The primary endpoint was a composite 30-day major adverse cardiovascular event (MACE), which included death, urgent target-vessel revascularization (TVR), stroke, and non-fatal recurrent myocardial infarction (REMI). The c-statistics of the tested scores for 30-day MACE or area under the receiver operating characteristic curve (AUC) with confidence intervals (CI) were as follows: RISK-PCI (AUC=0.94; 95% CI 1.790-4.353), the GRACE score on admission (AUC=0.73; 95% CI 1.013-1.045), the GRACE score on discharge (AUC=0.65; 95% CI 0.999-1.033). The RISK-PCI score was the only score that could predict TVR (AUC=0.91; 95% CI 1.392-2.882). The RISK-PCI scoring system showed an excellent discriminative potential for 30-day death (AUC=0.96; 95% CI 1.339-3.548) in comparison with the GRACE scores on admission (AUC=0.88; 95% CI 1.018-1.072) and on discharge (AUC=0.78; 95% CI 1.000-1.058). In comparison with the GRACE and TIMI scores, RISK-PCI score showed a non-inferior ability to predict 30-day MACE and death in ACS patients. Moreover, RISK-PCI was the only scoring system that could predict recurrent ischemia requiring TVR.

  17. Effects of Italian smoking regulation on rates of hospital admission for acute coronary events: a country-wide study.

    Full Text Available BACKGROUND: Several studies have reported a reduction in acute coronary events (ACEs in the general population after the enforcement of smoking regulations, although there is uncertainty concerning the magnitude of the effect of such interventions. We conducted a country-wide evaluation of the health effects of the introduction of a smoking ban in public places, using data on hospital admissions for ACEs from the Italian population after the implementation of a national smoking regulation in January 2005. METHODS AND FINDINGS: Rates of admission for ACEs in the 20 Italian regions from January 2002 to November 2006 were analysed using mixed-effect regression models that allowed for long-term trends and seasonality. Standard methods for interrupted time-series were adopted to assess the immediate and gradual effects of the smoking ban. Effect modification by age was investigated, with the assumption that exposure to passive smoking in public places would be greater among young people. In total, 936,519 hospital admissions for ACEs occurred in the Italian population during the study period. A 4% reduction in hospital admissions for ACEs among persons aged less than 70 years was evident after the introduction of the ban (Rate Ratio [RR], 0.96; 95% Confidence Interval [CI], 0.95-0.98. No effect was found among persons aged at least 70 years (RR 1.00; 95% CI 0.99-1.02. Effect modification by age was further suggested by analyses using narrower age categories. CONCLUSIONS: Smoke-free policies can constitute a simple and inexpensive intervention for the prevention of cardiovascular diseases and thus should be included in prevention programmes.

    Causal factors in aviation accidents and incidents related to system/component failure/malfunction (SCFM) were examined for Federal Aviation Regulation Parts 121 and 135 operations to establish future requirements for the NASA Aviation Safety Program s Integrated Vehicle Health Management (IVHM) Project. Data analyzed includes National Transportation Safety Board (NSTB) accident data (1988 to 2003), Federal Aviation Administration (FAA) incident data (1988 to 2003), and Aviation Safety Reporting System (ASRS) incident data (1993 to 2008). Failure modes and effects analyses were examined to identify possible modes of SCFM. A table of potential adverse conditions was developed to help evaluate IVHM research technologies. Tables present details of specific SCFM for the incidents and accidents. Of the 370 NTSB accidents affected by SCFM, 48 percent involved the engine or fuel system, and 31 percent involved landing gear or hydraulic failure and malfunctions. A total of 35 percent of all SCFM accidents were caused by improper maintenance. Of the 7732 FAA database incidents affected by SCFM, 33 percent involved landing gear or hydraulics, and 33 percent involved the engine and fuel system. The most frequent SCFM found in ASRS were turbine engine, pressurization system, hydraulic main system, flight management system/flight management computer, and engine. Because the IVHM Project does not address maintenance issues, and landing gear and hydraulic systems accidents are usually not fatal, the focus of research should be those SCFMs that occur in the engine/fuel and flight control/structures systems as well as power systems.

    Cardiovascular disease (CVD) disproportionately affects disadvantaged people, but reliable quantitative evidence on socioeconomic variation in CVD incidence in Australia is lacking. This study aimed to quantify socioeconomic variation in rates of primary and secondary CVD events in mid-age and older Australians. Baseline data (2006-2009) from the 45 and Up Study, an Australian cohort involving 267,153 men and women aged ≥ 45, were linked to hospital and death data (to December 2013). Outcomes comprised first event - death or hospital admission - for major CVD combined, as well as myocardial infarction and stroke, in those with and without prior CVD (secondary and primary events, respectively). Cox regression estimated hazard ratios (HRs) for each outcome in relation to education (and income and area-level disadvantage), separately by age group (45-64, 65-79, and ≥ 80 years), adjusting for age and sex, and additional sociodemographic factors. There were 18,207 primary major CVD events over 1,144,845 years of follow-up (15.9/1000 person-years), and 20,048 secondary events over 260,357 years (77.0/1000 person-years). For both primary and secondary events, incidence increased with decreasing education, with the absolute difference between education groups largest for secondary events. Age-sex adjusted hazard ratios were highest in the 45-64 years group: for major CVDs, HR (no qualifications vs university degree) = 1.62 (95% CI: 1.49-1.77) for primary events, and HR = 1.49 (1.34-1.65) for secondary events; myocardial infarction HR = 2.31 (1.87-2.85) and HR = 2.57 (1.90-3.47) respectively; stroke HR = 1.48 (1.16-1.87) and HR = 1.97 (1.42-2.74) respectively. Similar but attenuated results were seen in older age groups, and with income. For area-level disadvantage, CVD gradients were weak and non-significant in older people (> 64 years). Individual-level data are important for quantifying socioeconomic variation in CVD incidence, which

    The myocardial bridge (MB) is defined as a segment of an epicardial coronary artery that has an intramural course in the myocardium. Although MB is clinically silent in most cases, has been associated with myocardial ischemia, arrhythmias and sudden death. Coronary conventional angiography is the gold standard for detection of MB, but is invasive and cannot be sufficiently sensitive compared to autopsy studies. Recently, multislice computed tomography of coronary arteries (MCTCA) has allowed the detection of coronary artery course, including PM. Objectives: to evaluate MB prevalence in patients with suspected coronary artery disease undergoing MCTCA and to evaluate the predictive value of this method at medium term. Methods: during the period 2008 to 2011, 498 consecutive patients were examined by TMC for the diagnosis of coronary artery disease, being conducted to evaluate the presence of BM and followed for a mean follow-up of 23 months for the occurrence of cardiovascular hard events (death, hospitalization or revascularization). Results: patients mean age was 55.3 ± 14.2, being male 71.1%. Among the patients, 7.6% (38 patients) showed MB. Main findings included angina pectoris in 40% and a positive stress test in 34%. 34.2% had atherosclerotic disease, and one patient had significant coronary stenosis. During follow-up, no patients showed adverse events. Conclusion: MCTCA is a noninvasive technique with high accuracy in anatomical evaluation of the coronary arteries and may be particularly useful to assess the incidence, location and morphology of myocardial bridging in vivo.

    To systematically review the incidence rate of adverse drug reaction/event by Qingkailing injection. Such databases as the PubMed, EMbase, the Cochrane library, CNKI, VIP WanFang data and CBM were searched by computer from foundation to July 30, 2015. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and cross check data. Then, Meta-analysis was performed by using the R 3.2.0 software, subgroup sensitivity analysis was performed based on age, mode of medicine, observation time and research quality. Sixty-three studies involving 9,793 patients with Qingkailing injection were included, 367 cases of adverse reactions/events were reported in total. The incidence rate of adverse reaction in skin and mucosa group was 2% [95% CI (0.02; 0.03)]; the digestive system adverse reaction was 6% [95% CI(0.05; 0.07); the injection site adverse reaction was 4% [95% CI (0.02; 0.07)]. In the digestive system as the main types of adverse reactions/events, incidence of children and adults were 4.6% [0.021 1; 0.097 7] and 6.9% [0.053 5; 0.089 8], respectively. Adverse reactions to skin and mucous membrane damage as the main performance/event type, the observation time > 7 days and ≤ 7 days incidence of 3% [0.012 9; 0.068 3] and 1.9% [0.007 8; 0.046 1], respectively. Subgroup analysis showed that different types of adverse reactions, combination in the incidence of adverse reactions/events were higher than that of single drug, the difference was statistically significant (P reactions occur, and clinical rational drug use, such as combination, age and other fators, and the influence factors vary in different populations. Therefore, clinical doctors for children and the elderly use special care was required for a clear and open spirit injection, the implementation of individualized medication.

    The aim of this study was to clarify incidence and severity of oral adverse events induced by chemoradiotherapy and to explore efficient nursing-intervention or oral-care for the oral complications. Seventy-nine subjects who were treated with chemoradiotherapy at the radiation oncology unit of Gunma University Hospital were retrospectively analyzed using collected data from patients' medical chart including location of tumor, details of treatment, incidence and care of oral adverse events. Oral adverse events occurred in 7 (9%) of 79 patients. The complication rate in patients with lung or esophageal cancer was much higher than that with rectal or cervical cancer. All patients with the events received a total irradiation dose of 60 Gy in 30 fractions or higher. Oral mucositis was observed in 5 patients given antimetabolic chemotherapeutic agents, but they were successfully treated with steroids and/or gargles. Our results suggest that early intervention of oral care may reduce risks of developing severe oral adverse effects induced by chemoradiotherapy. (author)

    To evaluate the potential differences in risk factors' profile for in-hospital mortality and up to 1-year prognosis, between younger and older patients with first acute coronary syndromes (ACS). From October 2003 to September 2004, 1323 patients with first ACS event from 6 urban and rural Greek hospitals were enrolled into the study, classified as those period of 6-months, the event-rate was higher among the younger patients (p < 0.001). Current smoking was associated with increased risk of 1-month recurrent events, in patients < 65 years (p < 0.05). Myocardial infarction and history of diabetes were associated with increased risk in older patients (p < 0.1). Age-specific identification of the risk factors for recurrent events may have important clinical and public health implications and lead to the development of more effective risk reduction strategies.

    We evaluated the process of changing from conventional coronary artery bypass grafting (CABG) to totally arterial off-pump coronary artery bypass (TOPCAB) at a single heart center in Germany. We (1) used multivariate statistical methods to assess real-time monitoring of OPCAB effects, (2) conducted a case review to assess preventable deaths and identify areas of improvement, (3) conducted a team survey, and (4) evaluated benchmarking results. All surgeons and assistants (n = 18) at this center were involved and were guided by the department head and one of the consultants, who was trained in this procedure in 2004 at the Leuven OPCAB school. The frequency of OPCAB operations increased abruptly in 2005 from 5% to 43% and then increased gradually to 67% (n = 546) by 2008 (total, 1781 OPCAB cases and 1563 on-pump cases). The in-hospital and 30-day mortality rates for OPCAB surgeries (n = 10 [0.6%] and 21 [1.2%], respectively) were lower than for on-pump surgeries (n = 27 [1.7%] and 26 [1.7%], respectively). Stroke rates were also lower for OPCAB surgeries (7 cases [0.4%] versus 15 cases [1%]). The lower risk of stroke in the OPCAB group was significant (P popularity, and a top national rank). The change from conventional CABG to TOPCAB was effective in decreasing the incidence and severity of stroke, in developing a team routine and a positive team attitude, and in producing excellent benchmarking results. The presence of a training and communication deficiency at the beginning of the study suggested an area for further improvement. After 6 years TOPCAB had largely replaced conventional CABG.

    Full Text Available Social networking and network socialization provide abundant text information and social relationships into our daily lives. Making full use of these data in the big data era is of great significance for us to better understand the changing world and the information-based society. Though politics have been integrally involved in the hyperlinked world issues since the 1990s, the text analysis and data visualization of geo-events faced the bottleneck of traditional manual analysis. Though automatic assembly of different geospatial web and distributed geospatial information systems utilizing service chaining have been explored and built recently, the data mining and information collection are not comprehensive enough because of the sensibility, complexity, relativity, timeliness, and unexpected characteristics of political events. Based on the framework of Heritrix and the analysis of web-based text, word frequency, sentiment tendency, and dissemination path of the Huangyan Island incident were studied by using web crawler technology and the text analysis. The results indicate that tag cloud, frequency map, attitudes pie, individual mention ratios, and dissemination flow graph, based on the crawled information and data processing not only highlight the characteristics of geo-event itself, but also implicate many interesting phenomenon and deep-seated problems behind it, such as related topics, theme vocabularies, subject contents, hot countries, event bodies, opinion leaders, high-frequency vocabularies, information sources, semantic structure, propagation paths, distribution of different attitudes, and regional difference of net citizens’ response in the Huangyan Island incident. Furthermore, the text analysis of network information with the help of focused web crawler is able to express the time-space relationship of crawled information and the information characteristic of semantic network to the geo-events. Therefore, it is a useful tool to

    The clinical decision to treat hypercholesterolemia is premised on an awareness of patient risk, and cardiac risk prediction models offer a practical means of determining such risk. However, these models are based on observational cohorts where estimates of the treatment benefit are largely inferred. The West of Scotland Coronary Prevention Study (WOSCOPS) provides an opportunity to develop a risk-benefit prediction model from the actual observed primary event reduction seen in the trial. Five-year Cox model risk estimates were derived from all WOSCOPS subjects (n = 6,595 men, aged 45 to 64 years old at baseline) using factors previously shown to be predictive of definite fatal coronary heart disease or nonfatal myocardial infarction. Model risk factors included age, diastolic blood pressure, total cholesterol/ high-density lipoprotein ratio (TC/HDL), current smoking, diabetes, family history of fatal coronary heart disease, nitrate use or angina, and treatment (placebo/ 40-mg pravastatin). All risk factors were expressed as categorical variables to facilitate risk assessment. Risk estimates were incorporated into a simple, hand-held slide rule or risk tool. Risk estimates were identified for 5-year age bands (45 to 65 years), 4 categories of TC/HDL ratio ( or = 7.5), 2 levels of diastolic blood pressure ( or = 90 mm Hg), from 0 to 3 additional risk factors (current smoking, diabetes, family history of premature fatal coronary heart disease, nitrate use or angina), and pravastatin treatment. Five-year risk estimates ranged from 2% in very low-risk subjects to 61% in the very high-risk subjects. Risk reduction due to pravastatin treatment averaged 31%. Thus, the Cardiovascular Event Reduction Tool (CERT) is a risk prediction model derived from the WOSCOPS trial. Its use will help physicians identify patients who will benefit from cholesterol reduction.

    Human error classification systems theoretically allow researchers to analyze postaccident data in an objective and consistent manner. The Human Factors Analysis and Classification System (HFACS) framework is one such practical analysis tool that has been widely used to classify human error in aviation. The Cognitive Error Taxonomy (CET) is another. It has been postulated that the focus on interrelationships within HFACS can facilitate the identification of the underlying causes of pilot error. The CET provides increased granularity at the level of unsafe acts. The aim was to analyze the influence of factors at higher organizational levels on the unsafe acts of front-line operators and to compare the errors of fixed-wing and rotary-wing operations. This study analyzed 288 aircraft incidents involving human error from an Australasian military organization occurring between 2001 and 2008. Action errors accounted for almost twice (44%) the proportion of rotary wing compared to fixed wing (23%) incidents. Both classificatory systems showed significant relationships between precursor factors such as the physical environment, mental and physiological states, crew resource management, training and personal readiness, and skill-based, but not decision-based, acts. The CET analysis showed different predisposing factors for different aspects of skill-based behaviors. Skill-based errors in military operations are more prevalent in rotary wing incidents and are related to higher level supervisory processes in the organization. The Cognitive Error Taxonomy provides increased granularity to HFACS analyses of unsafe acts.

    Data on the associations between circulating magnesium (Mg) levels and incidence of coronary heart diseases (CHD), hypertension, and type 2 diabetes mellitus (T2DM) are inconsistent and inconclusive. The aim of this study was to examine circulating Mg levels in relation to incidence of CHD, hypertension, and T2DM. Prospective cohort studies published before May 2017 were searched through PubMed, EmBase, SCOPUS, and Google Scholar. A total of 11 studies that reported multivariable-adjusted associations of interest were identified. Information on the characteristics of study and participants, exposure, main outcomes, risk estimates, and cofounders was extracted and analyzed. Of the 11 included studies, 5 reported results on CHD (38,808 individuals [4437 cases] with an average 10.5-year follow-up), 3 on hypertension (14,876 participants [3149 cases] with a 6.7-year follow-up), and 4 on T2DM (31,284 participants [2680 cases] with an 8.8-year follow-up). Comparing the highest to the lowest category of circulating Mg concentration, the pooled relative risks [RRs] (95% confidence intervals [CIs]) were 0.86 (0.74, 0.996), 0.91 (0.80, 1.02), and 0.64 (0.50, 0.81) for incidence of CHD, hypertension, and T2DM, respectively. Every 0.1 mmol/L increment in circulating Mg levels was associated with 4% (RR, 0.96; 95% CI: 0.94, 0.99) reduction in hypertension incidence. No significant linear association was found between circulating Mg levels and incidence of CHD (RR, 0.89; 95% CI: 0.77, 1.03) and T2DM (RR, 0.90; 95% CI: 0.81, 1.002). The observed associations of interest were sensitive to exclusion of individual studies. Findings in this meta-analysis suggest that circulating Mg levels are inversely associated with incidence of CHD, hypertension, and T2DM. Additional studies are needed to provide more solid evidence and identify the optimal range of circulating Mg concentration with respect to primary prevention of CHD, hypertension, and T2DM.

  16. Masking in reports of "most serious" events: bias in estimators of sports injury incidence in Canadian children

    2016-08-01

    Full Text Available Introduction: Surveys that collect information on injuries often focus on the single "most serious" event to help limit recall error and reduce survey length. However, this can mask less serious injuries and result in biased incidence estimates for specific injury subcategories. Methods: Data from the 2002 Health Behaviour in School-aged Children (HBSC survey and from the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP were used to compare estimates of sports injury incidence in Canadian children. Results: HBSC data indicate that 6.7% of children report sustaining a sports injury that required an emergency department (ED visit. However, details were only collected on a child's "most serious" injury, so children who had multiple injuries requiring an ED visit may have had sports injuries that went unreported. The rate of 6.7% can be seen to be an underestimate by as much as 4.3%. Corresponding CHIRPP surveillance data indicate an incidence of 9.9%. Potential masking bias is also highlighted in our analysis of injuries attended by other health care providers. Conclusion: The "one most serious injury" line of questioning induces potentially substantial masking bias in the estimation of sports injury incidence, which limits researchers' ability to quantify the burden of sports injury. Longer survey recall periods naturally lead to greater masking. The design of future surveys should take these issues into account. In order to accurately inform policy decisions and the direction of future research, researchers must be aware of these limitations.

  17. Incidents in transport of radioactive materials for civil use: IRSN draws lessons from events reported between 1999 and 2007

    International Nuclear Information System (INIS)

    2008-01-01

    Some 900,000 packages of radioactive materials for civil use are transported each year in France. The great majority of these shipments involve radioactive materials used in the fields of medicine, pharmaceuticals, industry or property. Transport of radioactive materials linked to the nuclear fuel cycle actually represents only 15% of transport. A great variety of material is transported, differing in weight (from a few grams to tens of tons), form, activity and packaging. The associated risks are also different: radioactive contamination, external exposure to ionising radiation, chemical risk etc. In its role of technical support to safety and radioprotection authorities, IRSN's mission is to assess the design, manufacturing, testing and use of packaging and transport systems. The Institute is also involved in the management and analysis of events that occur during transport of radioactive materials. To assist with this, the IRSN manages a database which lists reported deviations, anomalies, incidents and accidents (known in a generic way as 'events') relating to transport. With an aim of reduction of the risks related to transport, the feedback resulting from the thorough analysis of the notified events is capitalized by IRSN, just as the feedback of the assessments of the safety analysis reports of the various package designs. Based on these feedbacks, IRSN proposes axes of improvement relating to package designs and transport operations, and regulatory evolutions, as well as priority topics for the inspections carried out by the French Nuclear safety authority (ASN). The IRSN has carried out a transversal analysis of all events in transport of radioactive materials that occurred in France from 1999 to 2007 as listed in its database (i.e. 901 events). For each event, some 70 parameters have been recorded from the analysis of the notifications and reports of the events, transmitted by the operators (type of event, type of package, level on the INES scale).

    Full Text Available C-reactive protein is a powerful independent predictor of cardiovascular events in patients with coronary artery disease. The relation between C-reactive protein (CRP concentration and in-hospital outcome, after coronary artery bypass grafting (CABG, has not yet been established. The study aims to evaluate the predictive value of pre-operative CRP for in-hospital cardiovascular events after CABG surgery. High-sensitivity CRP (hs-CRP levels were measured pre-operatively on the day of surgery in 66 patients scheduled for elective on pump CABG surgery. Post-operative cardiovascular events such as death from cardiovascular causes, ischemic stroke, myocardial damage, myocardial infarction and low output heart failure were recorded. During the first 30 days after surgery, 54 patients were free from observed events and 14 developed the following cardiovascular events: 10 (15% had myocardial damage, four (6% had low output heart failure and two (3% suffered stroke. No patients died during the follow-up period. Serum concentration of hs-CRP ≥ 3.3 mg/l (cut-off point obtained by ROC analysis was related to higher risk of post-operative cardiovascular events (36% vs 6%, P = 0.01, myocardial damage (24% vs 6%, P = 0.04 and low output heart failure (12% vs 0%, P = 0.04. Multivariate logistic regression analysis showed that hs-CRP ≥ 3.3 mg/l ( P = 0.002, O.R.: 19.3 (95% confidence interval (CI 2.9-128.0, intra-operative transfusion of red blood cells ( P = 0.04, O.R.: 9.9 (95% C.I. 1.1-85.5 and absence of diuretics in daily antihypertensive treatment ( P = 0.02, O.R.: 15.1 (95% C.I. 1.4-160.6 were independent predictors of combined cardiovascular event. Patients having hs-CRP value greater or equal to 3.3 mg/l pre-operatively have an increased risk of post-operative cardiovascular events after on pump coronary artery bypass grafting surgery.

  19. Modeling time to recovery and initiating event frequency for loss of off-site power incidents at nuclear power plants

    1988-01-01

    Industry data representing the time to recovery of loss of off-site power at nuclear power plants for 63 incidents caused by plant-centered losses, grid losses, or severe weather losses are fit with exponential, lognormal, gamma and Weibull probability models. A Bayesian analysis is used to compare the adequacy of each of these models and to provide uncertainty bounds on each of the fitted models. A composite model that combines the probability models fitted to each of the three sources of data is presented as a method for predicting the time to recovery of loss of off-site power. The composite model is very general and can be made site specific by making adjustments on the models used, such as might occur due to the type of switchyard configuration or type of grid, and by adjusting the weights on the individual models, such as might occur with weather conditions existing at a particular plant. Adjustments in the composite model are shown for different models used for switchyard configuration and for different weights due to weather. Bayesian approaches are also presented for modeling the frequency of initiating events leading to loss of off-site power. One Bayesian model assumes that all plants share a common incidence rate for loss of off-site power, while the other Bayesian approach models the incidence rate for each plant relative to the incidence rates of all other plants. Combining the Bayesian models for the frequency of the initiating events with the composite Bayesian model for recovery provides the necessary vehicle for a complete model that incorporates uncertainty into a probabilistic risk assessment

    To evaluate the target lesion failure (TLF) rate of the SYNERGY stent in all-comers, multiethnic Asian population. Currently, most drug eluting stents deliver anti-proliferative drugs from a durable polymer which is associated with a risk of late stent thrombosis. The novel everolimus-eluting, platinum chromium SYNERGY stent is coated with a bioabsorbable abluminal polymer that resolves within 4 months. This was a prospective, single center registry of consecutive patients treated with the SYNERGY stent between December 2012 and April 2015. The primary outcome was the incidence of TLF, defined as the combination of cardiac death, target vessel myocardial infarction, or clinically driven target lesion revascularization (TLR) at 1 year. A total of 807 patients received the SYNERGY stent during the study period. One-year clinical outcome data was available for 765 patients (94.8%) and were considered for statistical analysis. The mean age was 60.7 ± 10.8 years, and 83.4% were males. Patients with acute myocardial infarction consisted of 50.3% (ST-segment elevation myocardial infarction: 23.0%, Non-ST-segment elevation myocardial infarction: 27.3%) of the study population. The treated lesions were complex (ACC/AHA type B2/C: 72.7%). The primary end point of TLF at 1 year was 5.8%. Rates of cardiac mortality, target vessel myocardial infarction, and TLR were 4.2, 1.0, and 1.3%, respectively, at 1 year. Predictors of the incidence and time to early TLF were female gender, Malay ethnicity, diabetes mellitus, acute myocardial infarction at presentation, a prior history of coronary artery bypass surgery and the presence of lesion calcification. The incidence of definite stent thrombosis was 0.4% at 1 year. In this registry, the use of the SYNERGY stent was associated with low rates of TLF at 1 year. © 2018 Wiley Periodicals, Inc.

    2014-01-01

    Background The purpose of this study was to estimate the incidence of fatal and non-fatal Low Speed Vehicle Run Over (LSVRO) events among children aged 0–15 years in Queensland, Australia, at a population level. Methods Fatal and non-fatal LSVRO events that occurred in children resident in Queensland over eleven calendar years (1999-2009) were identified using ICD codes, text description, word searches and medical notes clarification, obtained from five health related data bases across the continuum of care (pre-hospital to fatality). Data were manually linked. Population data provided by the Australian Bureau of Statistics were used to calculate crude incidence rates for fatal and non-fatal LSVRO events. Results There were 1611 LSVROs between 1999–2009 (IR = 16.87/100,000/annum). Incidence of non-fatal events (IR = 16.60/100,000/annum) was 61.5 times higher than fatal events (IR = 0.27/100,000/annum). LSVRO events were more common in boys (IR = 20.97/100,000/annum) than girls (IR = 12.55/100,000/annum), and among younger children aged 0–4 years (IR = 21.45/100000/annum; 39% or all events) than older children (5–9 years: IR = 16.47/100,000/annum; 10–15 years IR = 13.59/100,000/annum). A total of 896 (56.8%) children were admitted to hospital for 24 hours of more following an LSVRO event (IR = 9.38/100,000/annum). Total LSVROs increased from 1999 (IR = 14.79/100,000) to 2009 (IR = 18.56/100,000), but not significantly. Over the 11 year period, there was a slight (non –significant) increase in fatalities (IR = 0.37-0.42/100,000/annum); a significant decrease in admissions (IR = 12.39–5.36/100,000/annum), and significant increase in non-admissions (IR = 2.02-12.77/100,000/annum). Trends over time differed by age, gender and severity. Conclusion This is the most comprehensive, population-based epidemiological study on fatal and non-fatal LSVRO events to date. Results from this study indicate

    Ibrutinib is associated with bleeding-related adverse events of grade ≤2 in severity, and infrequently with grade ≥3 events. To investigate the mechanisms of bleeding and identify patients at risk, we prospectively assessed platelet function and coagulation factors in our investigator-initiated trial of single-agent ibrutinib for chronic lymphocytic leukemia. At a median follow-up of 24 months we recorded grade ≤2 bleeding-related adverse events in 55% of 85 patients. No grade ≥3 events occurred. Median time to event was 49 days. The cumulative incidence of an event plateaued by 6 months, suggesting that the risk of bleeding decreases with continued therapy. At baseline, von Willebrand factor and factor VIII levels were often high and normalized on treatment. Platelet function measured via the platelet function analyzer (PFA-100™) was impaired in 22 patients at baseline and in an additional 19 patients on ibrutinib (often transiently). Collagen and adenosine diphosphate induced platelet aggregation was tested using whole blood aggregometry. Compared to normal controls, response to both agonists was decreased in all patients with chronic lymphocytic leukemia, whether on ibrutinib or not. Compared to untreated chronic lymphocytic leukemia patients, response to collagen showed a mild further decrement on ibrutinib, while response to adenosine diphosphate improved. All parameters associated with a significantly increased risk of bleeding-related events were present at baseline, including prolonged epinephrine closure time (HR 2.74, P=0.012), lower levels of von Willebrand factor activity (HR 2.73, P=0.009) and factor VIII (HR 3.73, P=0.0004). In conclusion, both disease and treatment-related factors influence the risk of bleeding. Patients at greater risk for bleeding of grade ≤2 can be identified by clinical laboratory tests and counseled to avoid aspirin, non-steroidal anti-inflammatory drugs and fish oils.

    Full Text Available Abstract Dual antiplatelet treatment with aspirin and clopidogrel is the antithrombotic treatment recommended after an acute coronary syndrome and/or coronary artery stenting. The evidence for optimal antiplatelet therapy for patients, in whom long-term treatment oral anticoagulation is mandatory, is however scarce. To evaluate the safety and efficacy of the various antithrombotic strategies adopted in this population, we reviewed the available evidence on the management of patients receiving oral anticoagulation, such as a vitamin-k-antagonists, referred for coronary artery stenting. Atrial fibrillation is the most frequent indication for oral anticoagulation. The need of starting antiplatelet therapy in this clinical scenario raises concerns about the combination to choose: triple therapy with warfarin, aspirin, and a thienopyridine being the most frequent and advised. The safety of this regimen appeared suboptimal because of an increased risk in hemorrhagic complications. On the other hand, the combination of oral anticoagulation and an antiplatelet agent is suboptimal in preventing thromboembolic events and stent thrombosis; dual antiplatelet therapy may be considered only when a high hemorrhagic risk and low thromboembolic risk are perceived. Indeed, the need for prolonged multiple-drug antithrombotic therapy increases the bleeding risks when drug eluting stents are used. Since current evidence derives mainly from small, single-center and retrospective studies, large-scale prospective multicenter studies are urgently needed.

    Amiodarone is a useful antiarrhythmic drug. Phlebitis, caused by intravenous amiodarone, is common in patients in coronary care units (CCUs). The aim of this study was to evaluate the effect of topical chamomile on the incidence of phlebitis due to the administration of an amiodarone infusion into the peripheral vein. This was a randomized, double-blind clinical trial, conducted on 40 patients (n = 20 per group) in two groups-an intervention group (chamomile ointment) and a control group (lanoline, as a placebo), hospitalized in the CCUs and undergoing an amiodarone infusion into the peripheral vein over 24 h. Following the cannulation and commencement of the infusion, placebo or chamomile ointment was rubbed in, up to 10 cm superior to the catheter and repeated every eight hours for three days. The cannula site was then assessed based on the phlebitis checklist. The incidence and time of occurrence of phlebitis, relative risk, severity of phlebitis were the main outcome measures. Nineteen patients (19/20) in the control group had phlebitis on the first day of the study and one patient (20/20) on the second day. In the intervention group, phlebitis occurred in 13 cases (13/20) on the first day and another two (2/7) was found on the second day. The incidence of phlebitis was significantly different between two groups (P = 0.023). The cumulative incidence of phlebitis in the intervention group (15/20) is significantly later and lower than that in the control group (20/20) during two days (P = 0.008). Two patients in the intervention group did not develop phlebitis at all during the 3-day study. Also, the relative risk of phlebitis in the two groups was 0.68 (P = 0.008 5). A significant difference was not observed with regard to phlebitis severity in both groups. It seems that phlebitis occurred to a lesser extent and at a later time frame in the intervention group compared to control group. Topical chamomile may be effective in decreasing the incidence of phlebitis

    A morphological study of coronary ostia was performed in 70 autopsied human hearts, with particular attention being focused on the funnel-shaped structure, aging changes, and relation to atherosclerosis. The following results were obtained: The ostium is particularly well-defined and forms a funnel-shaped structure. The structure is predominantly a double circular shape on the right and comet-shaped on the left. The funnel-shaped structure of coronary ostia is characterized by a longitudinal smooth muscle arrangement in the inner layer and circular one in the outer layer. Including overhang formation, coronary sclerosis of the ostium appears mainly on the upper margin of the funnel-shaped structure of the right ostium and at the upper right margin of the left. In ischemic heart disease, along with changes in coronary arteries themselves, changes in the ostia of these arteries should be paid close attention. Ostial stenosis of the coronary artery in the absence of distal vessel obstructions, isolated ostial stenosis, is a rare form of coronary artery disease. In a previous review of the international literature, the incidence of coronary ostial stenosis varied between 0.13% and 2.7%. Among 7,500 patients undergoing selective coronary cineangiography at Juntendo University Hospital and Juntendo Urayasu Hospital from 1975 to 1990, five women (0.07%) were diagnosed as having ''isolated coronary ostial stenosis'', of which the cause is unknown. Atherosclerosis, particularly early premature atherome, congenital coronary anomaly, fibro-muscular dysplasia, Takayasu's aortitis, humoral factors, spasm, and iatrogenic events have been considered as its causes. In contrast to usual atherosclerotic coronary artery disease, patients with isolated coronary ostial stenosis of unknown etiology were characterized as being middle-aged, premenopausal, slender females having few coronary risk factors, experiencing severe angina pector is with marked ischemic electrocardiogram changes

    In August 2005, New Orleans was hit by Hurricane Katrina, the costliest natural disaster in US history. Previous studies have shown an increase in acute myocardial infarction (AMI) in the immediate hours to weeks after natural disasters. The goals of our study were to detect any long-term increase in the incidence of AMI after Katrina and to investigate any pertinent contributing factors. This was a single-center retrospective cohort observational study. Patients admitted with AMI to Tulane Health Sciences Center hospital in the 2 years before Katrina and in the 2 years after the hospital reopened (5 months after Katrina) were identified from hospital records. The 2 groups (pre- and post-Katrina) were compared for prespecified demographic and clinical data. In the post-Katrina group, there were 246 admissions for AMI, out of a total census of 11,282 patients (2.18%), as compared with 150 AMI admissions out of a total of 21,229 patients (0.71%) in the pre-Katrina group (P affected (P housing (P = 0.003). The role of chronic stress in the pathogenesis of AMI is poorly understood, especially in the aftermath of natural disasters. Our data suggest that Katrina was associated with prolonged loss of employment and insurance, decreased access to preventive health services, and an increased incidence of AMI. In addition, it appears that chronic stress after a natural disaster can be associated with tobacco abuse and medication and therapeutic noncompliance. We found a 3-fold increased incidence of AMI more than 2 years after Hurricane Katrina. Even allowing for the loss of some local hospitals after the disaster, this represents a significant change in overall health of the study population and supports the need for further study into the health effects of chronic stress.

    With the social networking and network socialisation have brought more text information and social relationships into our daily lives, the question of whether big data can be fully used to study the phenomenon and discipline of natural sciences has prompted many specialists and scholars to innovate their research. Though politics were integrally involved in the hyperlinked word issues since 1990s, automatic assembly of different geospatial web and distributed geospatial information systems utilizing service chaining have explored and built recently, the information collection and data visualisation of geo-events have always faced the bottleneck of traditional manual analysis because of the sensibility, complexity, relativity, timeliness and unexpected characteristics of political events. Based on the framework of Heritrix and the analysis of web-based text, word frequency, sentiment tendency and dissemination path of the Huangyan Island incident is studied here by combining web crawler technology and the text analysis method. The results indicate that tag cloud, frequency map, attitudes pie, individual mention ratios and dissemination flow graph based on the data collection and processing not only highlight the subject and theme vocabularies of related topics but also certain issues and problems behind it. Being able to express the time-space relationship of text information and to disseminate the information regarding geo-events, the text analysis of network information based on focused web crawler technology can be a tool for understanding the formation and diffusion of web-based public opinions in political events.

    Purpose: 1) To define the incidence of isolated lung events in a cohort of women treated with conservative surgery (CS) and radiation therapy (RT) for early stage breast cancer. 2) Among such patients, to define the relative distribution of primary lung cancer, metastatic breast cancer, and indeterminate lesions; and to identify any predictors for a diagnosis of lung vs metastatic breast cancer. 3) To examine the cohort with respect to whether a higher than expected incidence of lung cancer is seen following breast irradiation. Materials and Methods: Between 1968 and 1986, 1865 patients with clinical stage I-II breast cancer were treated with CS and RT; the median follow-up for surviving patients is 129 months. The study population was limited to patients who developed a subsequent isolated lung event as the first site of distant disease. Isolated lung event was defined as disease limited to the thoracic cavity, without evidence of either uncontrolled local breast disease or metastatic disease elsewhere. Diagnosis of the lung event as a primary lung cancer, a metastatic breast lesion, or an indeterminate lesion was documented from the viewpoint of 1) the pathologic analysis and 2) the clinical impression at the time of the lung event. Results: Sixty six of the 1865 patients (3.5%) developed an isolated lung event. The relative distribution of the pathologic and clinical diagnoses is shown below: The 66 lung events were characterized either as a solitary pulmonary nodule (27), multiple nodules (23), pleural effusion alone (10), unknown (2), or miscellaneous other findings (4). Among the 47 patients for whom pathology was available, the diagnosis remained indeterminate for 24 (51%). For patients with a definitive pathologic diagnosis, 69% ((9(13))) of smokers had a new lung cancer compared to 20% ((2(10))) of non-smokers (p=0.036), and 67% ((10(15))) of patients with a solitary pulmonary nodule had lung cancer compared to 14% ((1(7))) for other lung presentations (p

    Full Text Available Background: Geriatric nutritional risk index (GNRI is a validated nutritional assessment method, and lower GNRI values are closely associated with adverse clinical outcomes in dialysis patients. This study investigated the impact of changes in GNRI during the first year of dialysis on cardiovascular outcomes in incident peritoneal dialysis (PD patients. Methods: We reviewed medical records in 133 incident PD patients to determine GNRI at the start of PD and after 12 months. Patients were categorized into improved (delta GNRI > 0 and worsening/stationary (delta GNRI ≤ 0 groups. The primary outcome was major adverse cardiac and cerebrovascular events (MACCEs. Results: During a mean follow-up of 51.1 months, the primary outcome was observed in 42 patients (31.6%. The baseline GNRI at PD initiation was not significantly associated with MACCEs (log-rank test, P = 0.40. However, the cumulative event-free rate was significantly lower in the worsening or stationary GNRI group than in the improved group (log-rank test, P = 0.004. Multivariate Cox analysis revealed that a worsening or stationary GNRI was independently associated with higher risk for MACCEs (hazard ratio, 2.47; 95% confidence interval, 1.15–5.29; P = 0.02. In subgroup analysis, patients with worsening or stationary GNRI were at significantly greater risk for MACCEs in both the lower (P = 0.04 and higher (P = 0.01 baseline GNRI groups. Conclusion: Baseline GNRI was not associated with MACCEs, but patients with deteriorating or stationary nutritional status were at significantly greater risk for MACCEs, suggesting that serial monitoring of nutritional status is important to stratify cardiovascular risk in incident PD patients.

    Normal stress myocardial perfusion images (MPI) generally show good prognosis for cardiovascular events. However, chronic kidney disease (CKD) is one of the important risk factors for coronary artery disease (CAD), and the interpretation of normal stress MPI has not been well established in CKD patients with no evidence of CAD. The purpose of this study was to evaluate the long-term prognostic value of stress MPI in CKD patients with no evidence of myocardial ischemia or infarction. Patients who had no history but were suspected of CAD and had normal stress MPI (n=307, male=208, age=67 years, CKD/non-CKD=46/261) were followed-up for 4.5 years. CKD was defined as a glomerular filtration ratio of 2 and/or persistent proteinuria. Cardiac death, non-fatal myocardial infarction, and unstable angina requiring hospitalization were defined as major cardiac events. Major cardiac events were observed in 3 of 261 (1.1%) non-CKD patients and 6 of 46 (13%) CKD patients (p<0.001, with log-rank test). CKD was an independent risk factor for major cardiac events (hazard ratio=13.1, p<0.001, multivariate Cox regression analysis). Normal stress MPI does not always promise a good prognosis for major cardiac events. Even in patients with no evidence of CAD from stress MPI, CKD can be an independent and significant risk factor for major cardiac events. (author)

  13. Plasminogen activator inhibitor-2 polymorphism associates with recurrent coronary event risk in patients with high HDL and C-reactive protein levels.

    James P Corsetti

    Full Text Available The objective of this work was to investigate whether fibrinolysis plays a role in establishing recurrent coronary event risk in a previously identified group of postinfarction patients. This group of patients was defined as having concurrently high levels of high-density lipoprotein cholesterol (HDL-C and C-reactive protein (CRP and was previously demonstrated to be at high-risk for recurrent coronary events. Potential risk associations of a genetic polymorphism of plasminogen activator inhibitor-2 (PAI-2 were probed as well as potential modulatory effects on such risk of a polymorphism of low-density lipoprotein receptor related protein (LRP-1, a scavenger receptor known to be involved in fibrinolysis in the context of cellular internalization of plasminogen activator/plansminogen activator inhibitor complexes. To this end, Cox multivariable modeling was performed as a function of genetic polymorphisms of PAI-2 (SERPINB, rs6095 and LRP-1 (LRP1, rs1800156 as well as a set of clinical parameters, blood biomarkers, and genetic polymorphisms previously demonstrated to be significantly and independently associated with risk in the study population including cholesteryl ester transfer protein (CETP, rs708272, p22phox (CYBA, rs4673, and thrombospondin-4 (THBS4, rs1866389. Risk association was demonstrated for the reference allele of the PAI-2 polymorphism (hazard ratio 0.41 per allele, 95% CI 0.20-0.84, p=0.014 along with continued significant risk associations for the p22phox and thrombospondin-4 polymorphisms. Additionally, further analysis revealed interaction of the LRP-1 and PAI-2 polymorphisms in generating differential risk that was illustrated using Kaplan-Meier survival analysis. We conclude from the study that fibrinolysis likely plays a role in establishing recurrent coronary risk in postinfarction patients with concurrently high levels of HDL-C and CRP as manifested by differential effects on risk by polymorphisms of several genes linked

    and occurrence of a first stroke was evaluated. Individual air pollution exposures were predicted from land-use regression models developed within the "European Study of Cohorts for Air Pollution Effects" (ESCAPE). The exposures were: PM2.5 (particulate matter [PM] below 2.5 µm in diameter), coarse PM (PM...... between 2.5 and 10 µm), PM10 (PM below 10 µm), PM2.5 absorbance, nitrogen oxides, and two traffic indicators. Cohort-specific analyses were conducted using Cox proportional hazards models. Random-effects meta-analysis was used for pooled effect estimation. RESULTS: 99,446 subjects were included, 3......,086 of whom developed stroke. A 5-μg/m(3) increase in annual PM2.5 exposure was associated with 19% increased risk of incident stroke (hazard ratio [HR] = 1.19, 95% confidence interval [CI]: 0.88, 1.62). Similar findings were obtained for PM10. The results were robust to adjustment for an extensive list...

    Measurement of testis volume (TV) is a reliable clinical procedure that predicts reproductive fitness. However, the role of TV in overall and cardiovascular (CV) fitness has never been studied. The study aims to analyze the clinical correlates of TV in patients with sexual dysfunction (SD) and to verify the value of this parameter and its determinants (i.e., luteinizing hormone [LH] levels) in predicting major adverse CV events (MACE). A consecutive series of 2,809 subjects without testiculopathy (age 51.2 ± 13.1) consulting for SD was retrospectively studied. A subset of this sample (n=1,395) was enrolled in a longitudinal study. Several clinical and biochemical parameters were investigated. After adjusting for confounders, TV was negatively associated with both LH (Adj. r=-0.234; PTV (hazard ratio [HR]=1.041 [1.021-1.061], PTV (Adj. r=0.157; PTV were only partially related to changes in gonadotropin levels. In the longitudinal analysis, after adjusting for confounders, TV was associated with a higher incidence of MACE (HR=1.066 [1.013-1.122]; P=0.014), and the stepwise introduction in the Cox model of lifestyle factors, mean blood pressure and body mass index progressively smoothed out the association, which was no longer statistically significant in the fully adjusted model. Conversely, the association of higher LH levels with increased incidence of MACE was not attenuated by the progressive introduction of the aforementioned confounders in the model. Our data show that in SD subjects, TV and LH are associated with an adverse CV risk profile that mediate the higher TV-associated incidence of MACE. High LH levels are an independent marker of CV risk. Further studies are needed for clarifying determinants and mechanisms of testis enlargement that, beyond gonadotropins, could mediate the increased incidence of MACE. © 2013 International Society for Sexual Medicine.

    Positive psychological constructs, such as optimism, are associated with beneficial health outcomes. However, no study has separately examined the effects of multiple positive psychological constructs on behavioral, biological, and clinical outcomes after an acute coronary syndrome (ACS). Accordingly, we aimed to investigate associations of baseline optimism and gratitude with subsequent physical activity, prognostic biomarkers, and cardiac rehospitalizations in post-ACS patients. Participants were enrolled during admission for ACS and underwent assessments at baseline (2 weeks post-ACS) and follow-up (6 months later). Associations between baseline positive psychological constructs and subsequent physical activity/biomarkers were analyzed using multivariable linear regression. Associations between baseline positive constructs and 6-month rehospitalizations were assessed via multivariable Cox regression. Overall, 164 participants enrolled and completed the baseline 2-week assessments. Baseline optimism was significantly associated with greater physical activity at 6 months (n=153; β=102.5; 95% confidence interval, 13.6-191.5; P=0.024), controlling for baseline activity and sociodemographic, medical, and negative psychological covariates. Baseline optimism was also associated with lower rates of cardiac readmissions at 6 months (n=164), controlling for age, sex, and medical comorbidity (hazard ratio, 0.92; 95% confidence interval, [0.86-0.98]; P=0.006). There were no significant relationships between optimism and biomarkers. Gratitude was minimally associated with post-ACS outcomes. Post-ACS optimism, but not gratitude, was prospectively and independently associated with superior physical activity and fewer cardiac readmissions. Whether interventions that target optimism can successfully increase optimism or improve cardiovascular outcomes in post-ACS patients is not yet known, but can be tested in future studies.

    The application of disease management algorithms by physician extenders has been shown to improve therapeutic adherence in selected populations. It is unknown whether this strategy would improve adherence to secondary prevention goals after acute coronary syndromes (ACSs) in a largely indigent county hospital setting. Patients admitted for ACS were randomized at the time of discharge to usual follow-up care versus the same care with the addition of a physician extender visit. Physician extender visits were conducted according to a treatment algorithm based on contemporary practice guidelines. Groups were compared using the primary end point of achievement of low-density lipoprotein treatment goals at 3 months after discharge and achievement of additional evidence-based practice goals. One hundred forty consecutive patients were randomized. A similar proportion of patients returned for study follow-up in both groups at 3 months (54 [79%]/68 in the usual care group vs 57 [79%]/72 in the intervention group; P = 0.97). Among those completing the 3-month visit, a low-density lipoprotein cholesterol level less than 100 mg/dL was achieved in 37 (69%) of the usual care patients compared with 35 (57%) of those in the intervention group (P = 0.43). There was no statistical difference in implementation of therapeutic lifestyle changes (smoking cessation, cardiac rehabilitation, or exercise) between groups. Prescription rates of evidence-based therapeutics at 3 months were similar in both groups. The implementation of a post-ACS clinic run by a physician extender applying a disease management algorithm did not measurably improve adherence to evidence-based secondary prevention treatment goals. Despite initially high rates of evidence-based treatment at discharge, adherence with follow-up appointments and sustained implementation of evidence-based therapies remains a significant challenge in this high-risk cohort.

    Objectives An additive genetic risk score (GRS) for coronary heart disease (CHD) has previously been associated with incident CHD in the population-based Greek European Prospective Investigation into Cancer and nutrition (EPIC) cohort. In this study, we explore GRS-‘environment’ joint actions on CHD for several conventional cardiovascular risk factors (ConvRFs), including smoking, hypertension, type-2 diabetes mellitus (T2DM), body mass index (BMI), physical activity and adherence to the Mediterranean diet. Design A case–control study. Setting The general Greek population of the EPIC study. Participants and outcome measures 477 patients with medically confirmed incident CHD and 1271 controls participated in this study. We estimated the ORs for CHD by dividing participants at higher or lower GRS and, alternatively, at higher or lower ConvRF, and calculated the relative excess risk due to interaction (RERI) as a measure of deviation from additivity. Results The joint presence of higher GRS and higher risk ConvRF was in all instances associated with an increased risk of CHD, compared with the joint presence of lower GRS and lower risk ConvRF. The OR (95% CI) was 1.7 (1.2 to 2.4) for smoking, 2.7 (1.9 to 3.8) for hypertension, 4.1 (2.8 to 6.1) for T2DM, 1.9 (1.4 to 2.5) for lower physical activity, 2.0 (1.3 to 3.2) for high BMI and 1.5 (1.1 to 2.1) for poor adherence to the Mediterranean diet. In all instances, RERI values were fairly small and not statistically significant, suggesting that the GRS and the ConvRFs do not have effects beyond additivity. Conclusions Genetic predisposition to CHD, operationalised through a multilocus GRS, and ConvRFs have essentially additive effects on CHD risk. PMID:24500614

    We examined the relationship between body mass index (BMI), waist circumference, and incident HF in men with and without pre-existing coronary heart disease (CHD) and assessed the contribution of plasma leptin concentration to these associations. Leptin has been proposed as a potential link between obesity and heart failure (HF). This was a prospective study of 4,080 men age 60 to 79 years with no diagnosed HF followed for a mean period of 9 years, in whom there were 228 incident HF cases. Increased BMI was associated with significantly increased risk of HF in men with and without pre-existing CHD (myocardial infarction or angina) after adjustment for cardiovascular risk factors including C-reactive protein. The adjusted hazard ratios (HRs) associated with a 1-SD increase in BMI were 1.37 (95% confidence interval [CI]: 1.09 to 1.72) and 1.18 (95% CI: 1.00 to 1.39) in men with and without CHD, respectively. Increased leptin was significantly associated with an increased risk of HF in men without pre-existing CHD, independent of BMI and potential mediators (adjusted HR for a 1-SD increase in log leptin: 1.30 [95% CI: 1.06 to 1.61]; p = 0.01). However, no association was seen in those with pre-existing CHD (corresponding HR: 1.06 [95% CI: 0.77 to 1.45]; p = 0.72). Adjustment for leptin abolished the association between BMI and HF in men with no CHD; in those with CHD, the association between BMI and HF remained significant (p = 0.03). Similar patterns were seen for waist circumference. In the absence of established CHD, the association between obesity and HF may be mediated by plasma leptin. In those with CHD, obesity appears to increase the risk of HF independent of leptin. Copyright © 2011 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.

    A study was made of the incidence of certain types of disease among Seventh-day Adventists, a religious group of special interest because they refrain from smoking and drinking. Epidermoid cancer of the lung, previously shown to be related to smoking, was 10 times less common among Seventh-day Adventists than among the general population, even among those Seventh-day Adventists living in the Los Angeles area where all are exposed to smog. Similarly, cancers of the mouth, larynx, and esophagus, previously shown to be related not only to smoking but also to heavy drinking, were at least 10 times less common among Seventh-day Adventist men than among men of the general population. All other types of cancer, with the exception of cancer of the bladder and cervix, occurred among Seventh-day Adventists with the same frequency as in the general population. The latter occurred slightly less than in the general population. Myocardial infarction in Seventh-day Adventist males was less frequent and occurred at a later age than among males in the general population; while the age distribution of the disease among the Seventh-day Adventist females was similar to that of females in the general population.

    Full Text Available BACKGROUND: Tuberculosis (TB and TB-human immunodeficiency virus infection (HIV coinfection is a major public health concern in resource-limited settings. Although TB treatment is challenging in HIV-infected patients because of treatment interactions, immunopathological reactions, and concurrent infections, few prospective studies have addressed this in sub-Saharan Africa. In this study we aimed to determine incidence, causes of, and risk factors for serious adverse events among patients on first-line antituberculous treatment, as well as its impact on antituberculous treatment outcome. METHODS AND FINDINGS: Prospective observational cohort study of adults treated for TB at the Internal Medicine department of the Kigali University Hospital from May 2008 through August 2009. Of 263 patients enrolled, 253 were retained for analysis: median age 35 (Interquartile range, IQR 28-40, 55% male, 66% HIV-positive with a median CD4 count 104 cells/mm(3 (IQR 44-248 cells/mm(3.

    Background Over the past five years, in most hospitals in England and Wales, incident reporting has become well established but it remains unclear how well reports match clinical adverse events. International epidemiological studies of adverse events are based on retrospective, multi‐hospital case record review. In this paper the authors describe the use of incident reporting, pharmacist surveillance and local real‐time record review for the recognition of clinical risks associated with hospital inpatient care. Methodology Data on adverse events were collected prospectively on 288 patients discharged from adult acute medical and surgical units in an NHS district general hospital using incident reports, active surveillance of prescription charts by pharmacists and record review at time of discharge. Results Record review detected 26 adverse events (AEs) and 40 potential adverse events (PAEs) occurring during the index admission. In contrast, in the same patient group, incident reporting detected 11 PAEs and no AEs. Pharmacy surveillance found 10 medication errors all of which were PAEs. There was little overlap in the nature of events detected by the three methods. Conclusion The findings suggest that incident reporting does not provide an adequate assessment of clinical adverse events and that this method needs to be supplemented with other more systematic forms of data collection. Structured record review, carried out by clinicians, provides an important component of an integrated approach to identifying risk in the context of developing a safety and quality improvement programme.

    We present a first description of a Heart Team (HT)-guided approach to coronary revascularization and its long-term effect on clinical events after percutaneous coronary intervention (PCI). The HT approach is a structured process to decide for coronary bypass grafting (CABG), PCI or conservative therapy in ad hoc situations as well as in HT conferences. As a hypothesis, during the long-term course after a PCI performed according to HT rules, a low number of late revascularizations, especially CABGs, are expected (F-PCI study). In this monocentric study, the HT approach to an all-comer population was first analyzed and described in general with the help of a database. Next the use of a HT approach was described for a more homogeneous subgroup with newly detected CAD (1.CAD). Those patients in whom the HT decision was PCI (which was a 1.PCI) were then studied with the help of questionnaires for clinical events during a very long-term follow-up. Events were CABG, PCI, diagnostic catheterization (DCath) and death. A significant number of patients were presented to HT conferences: 22 % out of all 11,174 catheterizations, 24 % out of all 7867 CAD cases and 35 % out of 3408 1.CAD cases. Most of these patients had multi-vessel disease (MVD). Conference decisions were isolated CABG in 46-66 %, PCI in 10-14 %, valvular surgery in 9-16 %, HTx in 10-21 % (Endstage heart failure candidates for surgery) and conservative therapy (Medical or no therapy, additional diagnostic procedures or no adherence to recommended therapy) in 2-3 %. However, most PCIs, ad hoc and elective, were performed under Heart Team rules, but without conference. During follow-up of 1.PCI patients (Kaplan-Meier analysis), CABG occurred in only 15 % of patients, PCI in 37 % and DCath in 65 %; mortality of any course was 51 %. Mortalities were similar in one-vessel disease and in a population of the same year, matched for age and sex (p PCI patients with MVD (p PCI) rates after a 1.PCI, without

    Background Evidence suggests that high-dose statin pretreatment may reduce the risk of periprocedural myocardial infarction (PMI) and major adverse cardiac events (MACE) for certain patients; however, previous analyses have not considered patients with a history of statin maintenance treatment. In this meta-analysis of randomized controlled trials (RCTs), we reevaluated the efficacy of short-term high-dose statin pretreatment to prevent PMI and MACE in an expanded set of patients undergoing elective percutaneous coronary intervention. Methods We searched the PubMed/Medline database for RCTs that compared high-dose statin pretreatment with no statin or low-dose statin pretreatment as a prevention of PMI and MACE. We evaluated the incidence of PMI and MACE, including death, spontaneous myocardial infarction, and target vessel revascularization at the longest follow-up for each study for subgroups stratified by disease classification and prior low-dose statin treatment. Results Twenty-four RCTs with a total of 5,526 patients were identified. High-dose statin pretreatment was associated with 59% relative reduction in PMI (odds ratio [OR]: 0.41; 95% confidence interval [CI]: 0.34–0.49; Pstatin pretreatment on MACE was significant for statin-naive patients (OR: 0.69; 95% CI: 0.50–0.95; P = 0.02) and prior low dose statin-treated patients (OR: 0.28; 95% CI: 0.12–0.65; P = 0.003); and for patients with acute coronary syndrome (OR: 0.52; 95% CI: 0.34–0.79; P = 0.003), but not for patients with stable angina (OR: 0.71; 95% CI 0.45–1.10; P = 0.12). Long-term effects on survival were less obvious. Conclusions High-dose statin pretreatment can result in a significant reduction in PMI and MACE for patients undergoing elective PCI. The positive effect of high-dose statin pretreatment on PMI and MACE is significant for statin-naïve patients and patients with prior treatment. The positive effect of high-dose statin pretreatment on MACE is significant for

    Our aim was to identify risk factors for coronary heart disease (CHD) events among asymptomatic persons with low (≤ 130 mg/dl) low-density lipoprotein cholesterol (LDL-C). Even among persons with low LDL-C, some will still experience CHD events and may benefit from more aggressive pharmacologic and lifestyle therapies. The MESA (Multi-Ethnic Study of Atherosclerosis) is a prospective cohort of 6,814 participants free of clinical cardiovascular disease. Of 5,627 participants who were not receiving any baseline lipid-lowering therapies, 3,714 (66%) had LDL-C ≤ 130 mg/dl and were included in the present study. Unadjusted and adjusted hazard ratios were calculated to assess the association of traditional risk factors and biomarkers with CHD events. To determine if subclinical atherosclerosis markers provided additional information beyond traditional risk factors, coronary artery calcium (CAC) and carotid intima media thickness were each separately added to the multivariable model. During a median follow-up of 5.4 years, 120 (3.2%) CHD events were observed. In unadjusted analysis, age, male sex, hypertension, diabetes mellitus, low high-density lipoprotein cholesterol (HDL-C), high triglycerides, and subclinical atherosclerosis markers (CAC >0; carotid intima media thickness ≥1 mm) predicted CHD events. Independent predictors of CHD events included age, male sex, hypertension, diabetes, and low HDL-C. After accounting for all traditional risk factors, the predictive value of CAC was attenuated but remained highly significant. The relationship of all independent clinical predictors remained robust even after accounting for elevated CAC. Among persons with low LDL-C, older age, male sex, hypertension, diabetes, and low HDL-C are associated with adverse CHD events. Even after accounting for all such variables, the presence of CAC provided incremental prognostic value. These results may serve as a basis for deciding which patients with low LDL-C may be considered for

    Full Text Available OBJECTIVE: To verify the results after the performance of primary coronary angioplasty in Brazil in the last 4 years. METHODS: During the first 24 hours of acute myocardial infarction onset, 9,434 (12.2% patients underwent primary PTCA. We analyzed the success and occurrence of major in-hospital events, comparing them over the 4-year period. RESULTS: Primary PTCA use increased compared with that of all percutaneous interventions (1996=10.6% vs. 2000=13.1%; p<0.001. Coronary stent implantation increased (1996=20% vs. 2000=71.9%; p<0.001. Success was greater (1998=89.5% vs. 1999=92.5%; p<0.001. Reinfarction decreased (1998=3.9% vs. 99=2.4% vs. 2000=1.5%; p<0.001 as did emergency bypass surgery (1996=0.5% vs. 2000=0.2%; p=0.01. In-hospital deaths remained unchanged (1996=5.7% vs. 2000=5.1%, p=0.53. Balloon PTCA was one of the independent predictors of a higher rate of unsuccessful procedures (odds ratio 12.01 [CI=95%] 1.58-22.94, and stent implantation of lower mortality rates (odds ratio 4.62 [CI=95%] 3.19-6.08. CONCLUSION: The success rate has become progressively higher with a significant reduction in reinfarction and urgent bypass surgery, but in-hospital death remains nearly unchanged. Coronary stenting was a predictor of a lower death rate, and balloon PTCA was associated with greater procedural failure.

    Type 2 diabetes mellitus (T2DM) carries significant risks for coronary heart disease (CHD). We examined the potential US population impact of single and composite risk factor control. Among US adults with diagnosed T2DM aged≥30 years in the National Health and Nutrition Examination Survey 2007 to 2012, we assessed CHD events preventable using the United Kingdom Prospective Diabetes Study CHD risk engine. We examined in all those not at goal the impact of statistical control of smoking, glycated hemoglobin, systolic blood pressure, and total and high-density lipoprotein cholesterol, according to the predefined criteria setting risk factors at different levels of control representing (1) "All to Goal," (2) at "Nominal Control," or (3) at "Aggressive Control." Preventable CHD events represented the difference between the number of events estimated from the control of these risk factors versus current levels of the risk factors. Of 606 men (representing 6.2 million) and 603 women (6.3 million) with DM and no previous CHD, 1.3 million men and 0.7 million women would develop a CHD event within 10 years if left uncontrolled. Controlling all risk factors to goal was projected to prevent 35% and 45% of CHD events in men and women, respectively. Nominal risk factor control was projected to prevent 36% and 38% and aggressive control 51% and 61% of CHD events, respectively. In conclusion, a significant proportion of CHD events in adults with T2DM could be prevented from composite control of risk factors often not at goal. Copyright © 2014 Elsevier Inc.

    To monitor the incidence change of acute coronary heart events in the all-ages farmers in Panyu District, Guangzhou City during 1991-2001 and 2010-2011. The surveillance on the same defined population as that from the PRC-USA cooperative epidemiologic project on the cardiovascular and pulmonary diseases 30-year ago was carried out in Panyu, Guangzhou in 1991-2001 and 2010-2011. The crude incidence of acute coronary events and the age-standardized incidence rate were calculated by the year, gender and age, and standardized with the world standard population age distribution. Incidences at the two different periods were compared. The annual average changing rate of the incidence was obtained by the regression analysis methods. In the 11 consecutive years of 1991-2001, a upward trend on the incidence of acute coronary events among the farmers in women in Panyu District was found (P acute coronary events in the year of 2010-2011 was significantly higher than that in the year of 1991 to 2001 [34.06 per 100 000 (age-adjusted rate as 28.50 per 100 000) versus 16.14 per 100 000 (age-adjusted rate as 16.57 per 100 000), P acute coronary events in males was noticed in 75-79 age group, and in 80-84 age group in females. Comparing to the period of 1991-2001, the largest incidence increases appeared in the age groups of 35-39 and 75-79 years in males, while in the age groups of 50-54 and 65-69 years in females. Up to 47.37% (36/76) events occurred on the age group older than 75 years, raised by 40.44% comparing to that in 1991-2001 (33.73%, 56/166). The incidence of acute coronary events among farmers in Panyu District is at middle or low level of China but there is an increasing trend in acute coronary incidence from 1991 to 2011. Our results suggest that the prevention and treatment on acute coronary syndrome should be strengthened, and especially on the age group with the largest increase of disease incidence.

    This study presents a quantitative analysis of the incidence of stressful life events (SLEs) and the variables gender, age at onset, family history and psychotic symptoms in patients with first-episode psychosis (FEP). A descriptive, cross-sectional methodology was used to interview 68 patients with FEP between 13 and 47 years of age. The Psychiatric Epidemiology Research Interview Life Events Scale collected one-year period prior to onset of FEP - used to analyse the subcategories academic, work, love and marriage, children, residence, legal affairs, finances and social activities-, Positive and Negative Syndrome Scale, and Clinical Global Impression-Schizophrenia scale were used to assess the relevance of certain SLEs during adolescence. Age at onset showed a significant negative correlation with the categories academic and social activities. By contrast, it showed a positive correlation with work and children. A significant relationship was found between paternal family history and social activities and between maternal family history and academic and love and marriage. Finally, an inverse relationship was observed between negative symptoms and the categories children and finance. Depressive symptoms were significantly correlated with the category academic. Our results show the importance of SLEs during adolescence and suggest that there is a clear need to develop preventive actions that promote effective strategies for dealing with the accumulation of psychosocial stress.

    A reduced risk of fatal coronary artery disease has been associated with a high intake of (n-3) fatty acids (FA) and a direct cardioprotective effect by their incorporation into myocardial cells has been suggested. Based on these observations, the omega-3 index (eicosapentaenoic acid + docosahexaenoic acid in cell membranes of RBC expressed as percent of total FA) has been suggested as a new risk marker for cardiac death. In this study, our aim was to evaluate the omega-3 index as a prognostic risk marker following hospitalization with an acute coronary syndrome (ACS). The omega-3 index was measured at admission in 460 patients with an ACS as defined by Troponin-T (TnT) > or = 0.02 microg/L. During a 2-y follow-up, recurrent myocardial infarctions (MI) (defined as TnT > 0.05 microg/L with a typical MI presentation) and cardiac and all-cause mortality were registered. Cox regression analyses were used to relate the risk of new events to the quartiles of the omega-3 index at inclusion. After correction for age, sex, previous heart disease, hypertension, diabetes, smoking, high-sensitivity C-reactive protein, brain natriuretic peptide, creatinine, total cholesterol, HDL-cholesterol, triacylglycerol, homocysteine, BMI, and medication, there was no significant reduction in risk for all-cause mortality, cardiac death, or MI with increasing values of the index. In conclusion, we could not confirm the omega-3 index as a useful prognostic risk marker following an ACS.

    Acute coronary syndromes (ACSs) are a major cause of morbidity and mortality, yet effective ACS treatments are frequently underused in clinical practice. Randomized trials including the CPACS-2 study suggest that quality improvement initiatives can increase the use of effective treatments, but whether such programs can impact hard clinical outcomes has never been demonstrated in a well-powered randomized controlled trial. The CPACS-3 study is a stepped-wedge cluster-randomized trial conducted in 104 remote level 2 hospitals without PCI facilities in China. All hospitalized ACS patients will be recruited consecutively over a 30-month period to an anticipated total study population of more than 25,000 patients. After a 6-month baseline period, hospitals will be randomized to 1 of 4 groups, and a 6-component quality improvement intervention will be implemented sequentially in each group every 6months. These components include the following: establishment of a quality improvement team, implementation of a clinical pathway, training of physicians and nurses, hospital performance audit and feedback, online technical support, and patient education. All patients will be followed up for 6months postdischarge. The primary outcome will be the incidence of in-hospital major adverse cardiovascular events comprising all-cause mortality, myocardial infarction or reinfarction, and nonfatal stroke. The CPACS-3 study will be the first large randomized trial with sufficient power to assess the effects of a multifaceted quality of care improvement initiative on hard clinical outcomes, in patients with ACS.

    The association between depression status and 10-year cardiovascular disease (CVD) incidence among acute coronary syndrome (ACS) patients, in relation to nutritional and financial status, was evaluated. From October 2003 to September 2004, a sample of 2172 consecutive ACS patients from 6 Greek hospitals was enrolled. In 2013-14, the 10-year follow-up was performed. Depressive symptoms were evaluated using the validated CES-D score (range 0-60). Adherence to Mediterranean diet was assessed through MedDietScore (range 0-55) and financial status was determined by the annual income. Ranking from the 1st to 3rd CES-D tertile, recurrent fatal/non fatal ACS rates were 33%, 37% and 42%, respectively (p=0.006). Multiple logistic regression models revealed an adverse association of severe depression status (i.e. 3rd tertile) compared to no depression (i.e. 1st tertile) [odds ratio (OR)=1.31, 95% confidence interval (95% CI) 1.01, 1.69]. When controlling for financial status, the relationship between depression and ACS prognosis remained marginally significant; while subgroup analysis revealed that only patients with low/moderate income were negatively affected [OR=1.36, 95% CI 0.98, 1.88]. Further stratified analysis, by MedDietScore group, was applied; the above association remained significant only in patients with low compliance to this dietary pattern [OR=1.68, 95% CI 1.10, 2.18]. ACS coexisting with severe depression status seems to result in adverse disease outcomes while financial status and Mediterranean diet are proposed as potential moderators. Public health programs should focus on vulnerable groups and minimize depressive symptoms through appropriate medical treatment and lifestyle interventions, so as to ameliorate the disease prognosis in clinical and community levels.

    Kampo medicine is traditional Japanese medicine, which originated in ancient traditional Chinese medicine, but was introduced and developed uniquely in Japan. Today, Kampo medicines are integrated into the Japanese national health care system. Incident reporting systems are currently being widely used to collect information about patient safety incidents that occur in hospitals. However, no investigations have been conducted regarding patient safety incident reports related to Kampo medicines. The aim of this study was to survey and analyse incident reports related to Kampo medicines in a Japanese university hospital to improve future patient safety. We selected incident reports related to Kampo medicines filed in Toyama University Hospital from May 2007 to April 2017, and investigated them in terms of medication errors and adverse drug events. Out of 21,324 total incident reports filed in the 10-year survey period, we discovered 108 Kampo medicine-related incident reports. However, five cases were redundantly reported; thus, the number of actual incidents was 103. Of those, 99 incidents were classified as medication errors (77 administration errors, 15 dispensing errors, and 7 prescribing errors), and four were adverse drug events, namely Kampo medicine-induced interstitial pneumonia. The Kampo medicine (crude drug) that was thought to induce interstitial pneumonia in all four cases was Scutellariae Radix, which is consistent with past reports. According to the incident severity classification system recommended by the National University Hospital Council of Japan, of the 99 medication errors, 10 incidents were classified as level 0 (an error occurred, but the patient was not affected) and 89 incidents were level 1 (an error occurred that affected the patient, but did not cause harm). Of the four adverse drug events, two incidents were classified as level 2 (patient was transiently harmed, but required no treatment), and two incidents were level 3b (patient was

    Human errors are common in clinical practice, but they are under-reported. As a result, very little is known of the types, antecedents and consequences of errors in nursing practice. This limits the potential to learn from errors and to make improvement in the quality and safety of nursing care. The aim of this study was to use an Organizational Accident Model to analyse critical incidents of errors in nursing. Twenty registered nurses were invited to produce a critical incident report of an error (which had led to an adverse event or potentially could have led to an adverse event) they had made in their professional practice and to write down their responses to the error using a structured format. Using Reason's Organizational Accident Model, supplemental information was then collected from five of the participants by means of an individual in-depth interview to explore further issues relating to the incidents they had reported. The detailed analysis of one of the incidents is discussed in this paper, demonstrating the effectiveness of this approach in providing insight into the chain of events which may lead to an adverse event. The case study approach using critical incidents of clinical errors was shown to provide relevant information regarding the interaction of organizational factors, local circumstances and active failures (errors) in producing an adverse or potentially adverse event. It is suggested that more use should be made of this approach to understand how errors are made in practice and to take appropriate preventative measures.

    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). 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. All-cause mortality and MACE. 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. 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.

    Despite diabetes patients' efforts to control their disease, many of them are confronted with an acute coronary event. This may evoke depressive feelings and self-management may be complicated. According to the American Diabetes Association, the transition from hospital to home after an acute coronary event (ACE) is a high-risk time for diabetes patients; it should be improved. Before developing an intervention for diabetes patients with an ACE in the period after discharge from hospital, we want to gain a detailed understanding of patients' views, perceptions and feelings in this respect. Qualitative design. Two semi-structured focus groups were conducted with 14 T2DM patients (71% male, aged 61-77 years) with a recent ACE. One focus group with partners (67% male, aged 64-75 years) was held. All interviews were transcribed verbatim and analyzed by two independent researchers. Patients believed that coping with an ACE differs between patients with and without T2DM. They had problems with physical exercise, sexuality and pharmacotherapy. Patients and partners were neither satisfied with the amount of information, especially on the combination of T2DM and ACE, nor with the support offered by healthcare professionals after discharge. Participants would appreciate tailored self-management support after discharge from hospital. Patients with T2DM and their partners lack tailored support after a first ACE. Our findings underpin the ADA recommendations to improve the transition from hospital to home. The results of our study will help to determine the exact content of a self-management support program delivered at home to help this specific group of patients to cope with both conditions.

    Background: small, retrospective studies suggest that major life events and/or sudden emotional stress may increase fall and fracture risk. The current study examines these associations prospectively. Methods: a total of 5,152 men aged ≥65 years in the Osteoporotic Fractures in Men study self-reported data on stressful life events for 1 year prior to study Visit 2. Incident falls and fractures were ascertained for 1 year after Visit 2. Fractures were centrally confirmed. Results: a total of 2,932 (56.9%) men reported ≥1 type of stressful life event. In men with complete stressful life event, fall and covariate data (n = 3,949), any stressful life event was associated with a 33% increased risk of incident fall [relative risk (RR) 1.33, 95% confidence interval (CI) 1.19–1.49] and 68% increased risk of multiple falls (RR = 1.68, 95% CI = 1.40–2.01) in the year following Visit 2 after adjustment for age, education, Parkinson's disease, diabetes, stroke, instrumental activities of daily living (IADL) impairment, chair stand time, walk speed, multiple past falls, depressive symptoms and antidepressant use. Risk increased with the number of types of stressful life events. Though any stressful life event was associated with a 58% increased age-adjusted risk for incident fracture, this association was attenuated and no longer statistically significant after additional adjustment for total hip bone mineral density, fracture after age 50, Parkinson's disease, stroke and IADL impairment. Conclusions: in this cohort of older men, stressful life events significantly increased risk of incident falls independent of other explanatory variables, but did not independently increase incident fracture risk.

    The importance of coronary anatomy in predicting cardiovascular events is well known. The use of traditional anatomical scores in routine angiography, however, has not been incorporated to clinical practice. SYNTAX score (SXscore) is a scoring system that estimates the anatomical extent of coronary artery disease (CAD). Its ability to predict outcomes based on a baseline diagnostic angiography has not been tested to date. To evaluate the performance of the SXscore in predicting major adverse cardiac events (MACE) in patients referred for diagnostic angiography. Prospective cohort of 895 patients with suspected CAD referred for elective diagnostic coronary angiography from 2008 to 2011, at a university-affiliated hospital in Brazil. They had their SXscores calculated and were stratified in three categories: no significant CAD (n = 495), SXscoreLOW-INTERMEDIATE: prospectiva de 895 pacientes com suspeita de DAC encaminhados para cineangiocoronariografia diagnóstica eletiva de 2008 a 2011, em hospital universitário no Brasil. Os pacientes tiveram seus SXescores calculados e foram estratificados em três categorias: 'sem DAC significativa' (n = 495); SXescoreBAIXO-INTERMEDIÁRIO: < 23 (n = 346); e SXescoreALTO: ≥ 23 (n = 54). O desfecho primário foi composto de morte cardíaca, infarto do miocárdio e revascularização tardia. Os desfechos secundários foram MACE e morte por todas as causas. Em média, os pacientes foram acompanhados por 1,8 ± 1,4 anos. Desfecho primário ocorreu em 2,2%, 15,3% e 20,4% nos grupos 'sem DAC significativa', SXescoreBAIXO-INTERMEDIÁRIO e SXescoreALTO, respectivamente (p < 0,001). Morte por todas as causas foi significativamente mais frequente no grupo de SXescoreALTO comparado ao grupo 'sem DAC significativa', 16,7% e 3,8% (p < 0,001), respectivamente. Após ajuste para fatores de confusão, todos os desfechos permaneceram associados com o SXescore. O SXescore prediz independentemente MACE em pacientes submetidos a

    Proteinuria was associated with cardiovascular events and mortality in community-based cohorts. The association of proteinuria with mortality and cardiovascular events in patients undergoing percutaneous coronary intervention (PCI) was unknown. The association of urinary dipstick proteinuria with mortality and cardiovascular events (composite of death, myocardial infarction, or nonhemorrhagic stroke) in 5,835 subjects of the EXCITE trial was evaluated. Dipstick urinalysis was performed before PCI, and proteinuria was defined as trace or greater. Subjects were followed up for 210 days/7 months after enrollment for the occurrence of events. Multivariate Cox regression analysis evaluated the independent association of proteinuria with each outcome. Mean age was 59 years, 21% were women, 18% had diabetes mellitus, and mean estimated glomerular filtration rate was 90 ml/min/1.73 m(2). Proteinuria was present in 750 patients (13%). During follow-up, 22 subjects (2.9%) with proteinuria and 54 subjects (1.1%) without proteinuria died (adjusted hazard ratio 2.83, 95% confidence interval [CI] 1.65 to 4.84, p use tool as urinary dipstick may be useful to identify and treat patients at high risk of mortality at the time of PCI.

    Full Text Available Elevated levels of matrix metalloproteinase (MMP-9 have been associated with the metabolic syndrome (MetS and cardiovascular events. The MMP-9 -1562 C/T polymorphism has furthermore been shown as a risk factor for coronary artery disease (CAD. The non-favourable cardiometabolic state in MetS may increase the risk. We aimed to investigate the influence of MMP-9 -1562 C/T polymorphism in subjects with CAD and MetS.Patients (n = 1000 with verified CAD stratified in Mets +/- (n = 244/756, were analyzed for the MMP-9 -1562 C/T polymorphism and related to clinical events after 2 years follow-up. Serum levels of total MMP-9 and tissue inhibitor of matrix metalloproteinases (TIMP-1 were analyzed in all, whereas MMP-9 activity, extracellular matrix metalloproteinase inducer (EMMPRIN, and expression of the two genes were analyzed in a subset of 240 randomly selected patients.Totally, 106 clinical endpoints were recorded. In MetS; the T-allele associated with 5.5 fold increase in event rate (p<0.0001, increased with number of MetS components, a 117% increase in total MMP-9 levels (TT homozygous, p = 0.05, significantly higher total- and endogenous active MMP-9 and TIMP-1 levels (p<0.01 all, and EMMPRIN was inversely correlated with pro- and endogenous active MMP-9 (p<0.05, both. In non-MetS; the T-allele was not associated with new events, nor higher MMP-9 levels. EMMPRIN was significantly correlated with total MMP-9 and TIMP-1 (p<0.01, both and the two genes were inter-correlated (p<0.001.In CAD patients with MetS, the MMP-9 T-allele increased the risk of clinical events, probably mediated through elevated MMP-9 levels and altered MMP-9 regulation.

    Randomized, controlled trials have demonstrated the superiority of sirolimus-eluting stent (SES) implantation during primary percutaneous coronary intervention (PCI), as opposed to bare-metal stents, in patients with ST-elevation myocardial infarction (STEMI). This study aimed to test the hypothesis that clinical benefits of SES treatment were independent of gender in this setting. A total of 2042 patients with STEMI undergoing SES-based primary PCI were prospectively enrolled into Shanghai Acute Coronary Event (SACE) registry (1574 men and 468 women). Baseline demographics, angiographic and PCI features, and in-hospital and 30-day major adverse cardiac events (MACE) were analyzed as a function of gender. Compared with men, women were older and more frequently had hypertension, diabetes, and hypercholesterolemia. Use of platelet glycoprotein IIb/IIIa receptor inhibitor (GPI, 65.5% vs. 62.2%, P = 0.10) and procedural success rate (95.0% vs. 94.2%, P = 0.52) were similar in both genders. In-hospital death and MACE occurred in 3.8% and 7.6%, and 4.5% and 8.1% in the male and female patients, respectively (all P > 0.05). At 30-day follow-up, survival (94.3% vs. 93.8%, P = 0.66) and MACE-free survival (90.2% vs. 89.3%, P = 0.52) did not significantly differ between men and women. After adjustment for differences in patient demographics, angiographic and procedural features, there were no significant difference in either in-hospital (OR = 0.77, 95%CI of 0.48 to 1.22, P = 0.30) or 30-day mortality (OR = 1.28, 95%CI of 0.73 to 2.23, P = 0.38) between women and men. Despite more advanced age and clustering of risk factors in women, female patients with STEMI treated by SES-based primary PCI had similar in-hospital and short-term clinical outcomes as their male counterparts.

    Highlights: • The incidence of silent in-stent restenosis at 1-year as revealed by CT is 7.6%. • The incidence of neointimal proliferation at 1-year as revealed by CT is 12.6%. • Diabetes are associated with higher incidence of neointimal proliferation. - Abstract: Objectives: To evaluate the incidence of coronary in-stent restenosis (ISR) and neointimal proliferation by coronary CT angiography (CCTA) at 1-year follow-up in asymptomatic patients. Methods: 234 patients (mean age: 67 ± 10.2 years, range 39–88 years, 180 males and 54 females) with 379 stents were prospectively enrolled in this study. Binary ISR was classified by CCTA into 4 types using Mehran classification. Neointimal proliferation was similarly classified into focal and diffuse types. All patients with CCTA-revealed ISR or neointimal proliferation underwent further invasive coronary angiography (ICA) for validation. Fisher's exact test was used for comparison. Results: ICA revealed patent stents with neointimal proliferation in 39 patients (16.7%, 39/234) and binary ISR in 23 patients (9.8%, 23/234). Lesion-based analysis showed 12 type I ISR lesions, 4 type II ISR lesions, 1 type III ISR lesion and 7 type IV ISR lesions. Among cases with neointimal proliferation, 27 lesions were classified as focal type whereas 13 lesions were classified as diffuse type. Patients with diabetes mellitus were associated with higher incidence of CCTA-revealed neointimal proliferation (21/77 vs. 18/157, p = 0.002) as well as ISR (12/77 vs. 11/157, p = 0.038), compared to patients without diabetes. CCTA was found to have good diagnostic performance for neointimal proliferation and ISR detection as well as classification, with an overall accuracy of 84.4% (54/64). Conclusions: Silent ISR as well as neointimal proliferation is not uncommon findings in asymptomatic post-stenting patients at 1-year interval, as revealed by CCTA. Patients with diabetes are prone to have higher incidence of neointimal

    The objective of this study was to determine if the extent of quantitative troponin elevation predicted mortality as well as in-hospital complications of cardiac arrest, new heart failure and cardiogenic shock. 16,318 patients with non-ST-segment elevation acute coronary syndromes (NSTE ACS) from the Global Registry of Acute Coronary Events (GRACE) were included. The maximum 24 h troponin value as a multiple of the local laboratory upper limit of normal was used. The population was divided into five groups based on the degree of troponin elevation, and outcomes were compared. An adjusted analysis was performed using quantitative troponin as a continuous variable with adjustment for known prognostic variables. For each approximate 10-fold increase in the troponin ratio, there was an associated increase in cardiac arrest, sustained ventricular tachycardia (VT) or ventricular fibrillation (VF) (1.0, 2.4, 3.4, 5.9 and 13.4%; p<0.001 for linear trend), cardiogenic shock (0.5, 1.4, 2.0, 4.4 and 12.7%; p<0.001), new heart failure (2.5, 5.1, 7.4, 11.6 and 15.8%; p<0.001) and mortality (0.8, 2.2, 3.0, 5.3 and 14.0%; p<0.001). These findings were replicated using the troponin ratio as a continuous variable and adjusting for covariates (cardiac arrest, sustained VT or VF, OR 1.56, 95% CI 1.39 to 1.74; cardiogenic shock, OR 1.87, 95% CI 1.61 to 2.18; and new heart failure, OR 1.57, 95% CI 1.45 to 1.71). The degree of troponin elevation was predictive of early mortality (HR 1.61, 95% CI 1.44 to 1.81; p<0.001 for days 0-14) and longer term mortality (HR 1.18, 95% CI 1.07 to 1.30, p=0.001 for days 15-180). The extent of troponin elevation is an independent predictor of morbidity and mortality.

    Full Text Available OBJECTIVE: To assess coronary stent placement in patients with multivessel coronary disease and involvement of the proximal portion of the anterior descending coronary artery. METHODS: We retrospectively analyzed the in-hospital and late evolution of 189 patients with multivessel coronary disease, who underwent percutaneous coronary stent placement. These patients were divided into 2 groups as follows: group I (GI - 59 patients with involvement of the proximal segment of the anterior descending coronary artery; and group II (GII - 130 patients without involvement of the proximal segment of the anterior descending coronary artery. RESULTS: No significant difference was observed in the success rate of the procedure (91.5% versus 97.6%, p=0.86, nor in the occurrence of major adverse cardiac events (5.1% versus 1.5%, p=0.38, nor in the occurrence of major vascular complications (1.7% versus 0%, p=0.69 in the in-hospital phase. In the late follow-up, the incidence of major adverse cardiac events (15.4% versus 13.7%, p=0.73 and the need for new revascularization (13.5% versus 10.3%, p=0.71 were similar for both groups. CONCLUSION: The in-hospital and late evolution of patients with multivessel coronary disease with and without involvement of the proximal segment of the anterior descending coronary artery treated with coronary stent placement did not differ. This suggests that this revascularization method is an effective procedure and a valuable option for treating these types of patients.

    Clinical outcomes and the effects of oral anticoagulants among patients with acute coronary syndrome (ACS) and either a history of or acute heart failure (HF) are largely unknown. We aimed to assess the relationship between prior HF or acute HF complicating an index ACS event and subsequent clinical outcomes and the efficacy and safety of apixaban compared with placebo in these populations. High-risk patients were randomly assigned post-ACS to apixaban 5.0 mg or placebo twice daily. Median follow-up was 8 (4-12) months. The primary outcome was cardiovascular death, myocardial infarction, or stroke. The main safety outcome was thrombolysis in myocardial infarction major bleeding. Heart failure was reported in 2,995 patients (41%), either as prior HF (2,076 [28%]) or acute HF (2,028 [27%]). Patients with HF had a very high baseline risk and were more often managed medically. Heart failure was associated with a higher rate of the primary outcome (prior HF: adjusted hazard ratio [HR] 1.73, 95% CI 1.42-2.10, P acute HF: adjusted HR 1.65, 95% CI 1.35-2.01, P acute HF: adjusted HR 2.52, 95% CI 1.82-3.50). Patients with acute HF also had significantly higher rates of thrombolysis in myocardial infarction major bleeding (prior HF: adjusted HR 1.22, 95% CI 0.65-2.27, P = .54, acute HF: adjusted HR 1.78, 95% CI 1.03-3.08, P = .04). There was no statistical evidence of a differential effect of apixaban on clinical events or bleeding in patients with or without prior HF; however, among patients with acute HF, there were numerically fewer events with apixaban than placebo (14.8 vs 19.3, HR 0.76, 95% CI 0.57-1.01, interaction P = .13), a trend that was not seen in patients with prior HF or no HF. In high-risk patients post-ACS, both prior and acute HFs are associated with an increased risk of subsequent clinical events. Apixaban did not significantly reduce clinical events and increased bleeding in patients with and without HF; however, there was a tendency toward fewer clinical

    Full Text Available Abstract Background Patient record review is believed to be the most useful method for estimating the rate of adverse events among hospitalised patients. However, the method has some practical and financial disadvantages. Some of these disadvantages might be overcome by using existing reporting systems in which patient safety issues are already reported, such as incidents reported by healthcare professionals and complaints and medico-legal claims filled by patients or their relatives. The aim of the study is to examine to what extent the hospital reporting systems cover the adverse events identified by patient record review. Methods We conducted a retrospective study using a database from a record review study of 5375 patient records in 14 hospitals in the Netherlands. Trained nurses and physicians using a method based on the protocol of The Harvard Medical Practice Study previously reviewed the records. Four reporting systems were linked with the database of reviewed records: 1 informal and 2 formal complaints by patients/relatives, 3 medico-legal claims by patients/relatives and 4 incident reports by healthcare professionals. For each adverse event identified in patient records the equivalent was sought in these reporting systems by comparing dates and descriptions of the events. The study focussed on the number of adverse event matches, overlap of adverse events detected by different sources, preventability and severity of consequences of reported and non-reported events and sensitivity and specificity of reports. Results In the sample of 5375 patient records, 498 adverse events were identified. Only 18 of the 498 (3.6% adverse events identified by record review were found in one or more of the four reporting systems. There was some overlap: one adverse event had an equivalent in both a complaint and incident report and in three cases a patient/relative used two or three systems to complain about an adverse event.

    Infection with Helicobacter pylori and Chlamydia pneumoniae is associated with coronary heart disease. We conducted an intervention study using antibiotics against these bacteria in patients with acute coronary syndromes to determine whether antibiotics reduce inflammatory markers and adverse cardiac events. Patients (n=325) admitted with acute myocardial infarction or unstable angina (acute coronary syndromes) were randomized to receive a 1-week course of 1 of 3 treatment regimens: (1) placebo; (2) amoxicillin (500 mg twice daily), metronidazole (400 mg twice daily), and omeprazole (20 mg twice daily); or (3) azithromycin (500 mg once daily), metronidazole (400 mg twice daily), and omeprazole (20 mg twice daily). Serum fibrinogen, white cell count, and high-sensitivity C-reactive protein were measured at study entry and at 1, 3, and 12 months during follow-up. Cardiac death and readmission with acute coronary syndrome were considered clinical end points. Patients were followed for 1 year. C-reactive protein levels were reduced (P=0.03) in unstable angina patients receiving amoxicillin, and fibrinogen was reduced in both patient groups receiving antibiotics (P=0.06). There were 17 cardiac deaths and 71 readmissions with acute coronary syndrome. No difference in frequency or timing of end points was observed between the 2 antibiotic groups. At 12 weeks, there was a 36% reduction in all end points in patients receiving antibiotics compared with placebo (P=0.02). This reduction persisted during the 1-year follow-up. Neither C pneumoniae nor H pylori antibody status was significantly related to response to treatment. Antibiotic treatment significantly reduced adverse cardiac events in patients with acute coronary syndromes, but the effect was independent of H pylori or C pneumoniae seropositivity.

    simulations based on Monte Carlo code form an essential component in the application of dose determinations by EPR and OSL to dose reconstruction problems. We include in the review examples where the translation from the physical quantity of cumulative dose determined in the sampled medium to a dose quantity that can be applied in the reconstruction of dose to individuals and/or populations; these take into account the source terms, release patterns and the movements of people in the affected areas. One role for retrospective luminescence dosimetry has been to provide benchmark dose determinations for testing the models employed in dose reconstruction for exposed populations, notably at Hiroshima and Nagasaki. The discussion is framed within the context of the well-known radiation incidents mentioned above. - Highlights: • Review of luminescence and EPR in retrospective and emergency dosimetry. • OSL, TL, and EPR results on biological and physical materials. • Use in emergency and retrospective dosimetry for large-scale radiological events.

    Electron-beam tomography (EBT) and multi-detector computed tomography (MDCT) enable the noninvasive assessment of coronary calcification. The amount of coronary calcification, as detected by EBT, has a close relation with the amount of coronary atherosclerosis, which is the substrate for the occurrence of myocardial infarction and sudden cardiac death. Calcification of the coronary arteries can be seen as a cumulative measure of life-time exposure to cardiovascular risk factors. Several studies have shown that the amount of coronary calcification is associated with the risk of coronary heart disease. Therefore, coronary calcification is a promising method for non-invasive detection of asymptomatic subjects at high risk of developing coronary heart disease. Whether measurement of coronary calcification also increases the predictive power of coronary events based on cardiovascular risk factors is topic of current research

    Acute myocardial infarction during pregnancy is associated with high maternal and fetal mortality. Coronary atherosclerosis is the most common cause due to an increase in the age of the patients and the association with cardiovascular risk factors such as smoking, hypertension, diabetes mellitus, preeclampsia, and the existence of family history of coronary disease. However, thrombosis, coronary dissection or coronary vasospasms are other causes that may justify it. We report the case of a 33 weeks pregnant first-time mother, without cardiovascular risk factors, who presented an acute coronary event in the context of atherosclerotic disease and coronary dissection after percutaneous coronary intervention.

    Few tools exist for assessing the risk for early atherosclerotic cardiovascular disease (ASCVD) events in young adults. To assess the performance of the Healthy Heart Score (HHS), a lifestyle-based tool that estimates ASCVD events in older adults, for ASCVD events occurring before 55 years of age. This prospective cohort study included 4893 US adults aged 18 to 30 years from the Coronary Artery Risk Development in Young Adults (CARDIA) study. Participants underwent measurement of lifestyle factors from March 25, 1985, through June 7, 1986, and were followed up for a median of 27.1 years (interquartile range, 26.9-27.2 years). Data for this study were analyzed from February 24 through December 12, 2016. The HHS includes age, smoking status, body mass index, alcohol intake, exercise, and a diet score composed of self-reported daily intake of cereal fiber, fruits and/or vegetables, nuts, sugar-sweetened beverages, and red and/or processed meats. The HHS in the CARDIA study was calculated using sex-specific equations produced by its derivation cohorts. The ability of the HHS to assess the 25-year risk for ASCVD (death from coronary heart disease, nonfatal myocardial infarction, and fatal or nonfatal ischemic stroke) in the total sample, in race- and sex-specific subgroups, and in those with and without clinical ASCVD risk factors at baseline. Model discrimination was assessed with the Harrell C statistic; model calibration, with Greenwood-Nam-D'Agostino statistics. The study population of 4893 participants included 2205 men (45.1%) and 2688 women (54.9%) with a mean (SD) age at baseline of 24.8 (3.6) years; 2483 (50.7%) were black; and 427 (8.7%) had at least 1 clinical ASCVD risk factor (hypertension, hyperlipidemia, or diabetes types 1 and 2). Among these participants, 64 premature ASCVD events occurred in women and 99 in men. The HHS showed moderate discrimination for ASCVD risk assessment in this diverse population of mostly healthy young adults (C statistic, 0

    Primary Care is the fundamental axis of our health system and obliges us to be consistent with our prescriptions. The non-steroidal anti-inflammatory drugs (NSAIDs) have been associated with increased cardiovascular risk and increased risk of all causes of death, as well as acute myocardial infarction (AMI) in patients with a previous myocardial infarction. Pain and cardiac patient management are 2 basic pillars in our daily activity, and we must know the limitations of NSAIDs in patients with established cardiovascular risk. We present a review of the scientific literature with primary interest in the role of NSAIDs and cardiovascular risk. The objective is to determine the relationship between the consumption of different NSAIDs and the fatal and non-fatal events among patients with known coronary disease. This is a review of the scientific literature with primary interest in the role of NSAIDs and cardiovascular risk. The literature review was conducted in PubMed search engines like Tripdatabase and with certain keywords. Of the 15 original papers found, 9 did not correspond completely to the central focus, so the approach was decided from 6 original articles from the past 5 years, which address the central focus of increased cardiovascular risk found (fatal and non-fatal events) in patients with prior cardiovascular disease or AMI being prescribed NSAIDs for any reason. The risk of fatal/non-fatal events in each of the studies is expressed by the odds ratio (OR)/hazard ratio (HR), defined as the probability of an event occurring. A moderate risk was observed for ibuprofen. It increases the risk of acute coronary syndrome after 5 years of cardiovascular event, especially in the 2nd year (OR 1.63; 95% CI 1.42-1.87). It also increases the risk of stroke (HR 1.23; 95% IC 1.10-1.38). Cyclo-oxygenase-2 inhibitors were the third risk group, after nabumetone and diclofenac. Celecoxib increases risk from the 14th day of treatment (HR 2.3; 95% CI 1.79-3.02), having an OR

    Full Text Available Abstract Background We need to know the scale and underlying causes of surgical adverse events (AEs in order to improve the safety of care in surgical units. However, there is little recent data. Previous record review studies that reported on surgical AEs in detail are now more than ten years old. Since then surgical technology and quality assurance have changed rapidly. The objective of this study was to provide more recent data on the incidence, consequences, preventability, causes and potential strategies to prevent AEs among hospitalized patients in surgical units. Methods A structured record review study of 7,926 patient records was carried out by trained nurses and medical specialist reviewers in 21 Dutch hospitals. The aim was to determine the presence of AEs during hospitalizations in 2004 and to consider how far they could be prevented. Of all AEs, the consequences, responsible medical specialty, causes and potential prevention strategies were identified. Surgical AEs were defined as AEs attributable to surgical treatment and care processes and were selected for analysis in detail. Results Surgical AEs occurred in 3.6% of hospital admissions and represented 65% of all AEs. Forty-one percent of the surgical AEs was considered to be preventable. The consequences of surgical AEs were more severe than for other types of AEs, resulting in more permanent disability, extra treatment, prolonged hospital stay, unplanned readmissions and extra outpatient visits. Almost 40% of the surgical AEs were infections, 23% bleeding, and 22% injury by mechanical, physical or chemical cause. Human factors were involved in the causation of 65% of surgical AEs and were considered to be preventable through quality assurance and training. Conclusions Surgical AEs occur more often than other types of AEs, are more often preventable and their consequences are more severe. Therefore, surgical AEs have a major impact on the burden of AEs during hospitalizations

    Business continuity management is often thought of as a proactive planning process for minimising impact from large-scale incidents and disasters. While this is true, and it is critical to plan for the worst, consistently validating plan effectiveness against smaller disruptions can enable an organisation to gain key insights about its business continuity readiness, drive programme improvements, reduce costs and provide an opportunity to quantitatively demonstrate the value of the programme to management. This paper describes a post mortem framework which is used as a continuous improvement mechanism for tracking, reviewing and learning from real-world events at Microsoft Customer Service & Support. This approach was developed and adopted because conducting regular business continuity exercises proved difficult and expensive in a complex and distributed operations environment with high availability requirements. Using a quantitative approach to measure response to incidents, and categorising outcomes based on such responses, enables business continuity teams to provide data-driven insights to leadership, change perceptions of incident root cause, and instil a higher level of confidence towards disaster response readiness and incident management. The scope of the framework discussed here is specific to reviewing and driving improvements from operational incidents. However, the concept can be extended to learning and evolving readiness plans for other types of incidents.

    Full Text Available To investigate if diet quality is related to incidence of cardiovascular (CV events.A diet quality index based on the 2005 Swedish Nutrition Recommendations and the Swedish Dietary Guidelines was created and included six dietary components: saturated fatty acids, polyunsaturated fatty acids, fish and shellfish, dietary fiber, fruit and vegetables, and sucrose. The index ranked 17126 participants (59% women of the population-based Malmö Diet and Cancer cohort (Sweden on their dietary intakes. Total index score was categorized as low, medium or high. Cox proportional hazard regression was used to model associations between index score categories and index components with risk of incident CV events, with adjustment for potential confounders. The incidence of first CV events (non-fatal or fatal myocardial infarction or ischemic stroke or death from ischemic heart disease was monitored from baseline (1991-1996 until December 31, 2008; 703 CV events occurred in women and 1093 in men.A high diet quality was associated with decreased risk of CV events when compared to a low diet quality. In multivariate analysis, the risk reduction was 32% (hazard ratio = 0.68, 95% confidence interval: 0.49-0.73 in men and 27% (hazard ratio = 0.73, 95% confidence interval: 0.59-0.91 in women. When examined separately and mutually adjusted for each other, the individual components were either not associated with CV risk or marginally decreased risks were seen.High quality diets in line with current recommendations may reduce the risk of CV events. This study illustrates the importance of considering a combination of dietary factors when evaluating diet-disease associations.

    To calculate the monthly incidence of gastric dilatation-volvulus (GDV) in a population of military working dogs during a 5-year period and determine whether there was an association with synoptic climatologic indices. Medical records of all military working dogs housed at Lackland Air Force Base,Tex, from Jan 1, 1993 to Dec 31, 1997. Confirmed cases of GDV were identified from evaluation of medical records and used to calculate incidence of GDV. Factor analysis of local climatologic data was used to classify each day into 1 of 8 meteorologically homogeneous types of days for this location. Occurrence of GDV was compared with frequency of occurrence of synoptic climatologic days. 48 cases of GDV were identified from January 1993 through December 1997 Mean monthly incidence was 2.5 cases/1,000 dogs at risk (range, 0 to 18.5 cases/1,000 dogs; median, 2.5 cases/1,000 dogs). A seasonal increase in incidence of GDV was detected, because half of the episodes were during November, December, and January. An association with a specific synoptic climatologic day was not detected. Seasonal fluctuations in incidence of GDV may be associated with external factors that precipitate physiologic changes resulting in GDV. Although a specific cause-effect relationship was not documented, clinicians must be alert for the potential of seasonal variation in incidence of GDV and accordingly heighten their index of suspicion for the condition, particularly in populations of dogs that are predisposed to development of GDV.

    Aortic valve calcification (AVC) is considered a manifestation of atherosclerosis. In this study, we investigated whether AVC adds to cardiovascular risk prediction beyond Framingham risk factors and coronary artery calcification (CAC). A total of 3944 subjects from the population based Heinz Nixdorf Recall Study (59.3±7.7 years; 53% females) were evaluated for coronary events, stroke, and cardiovascular disease (CVD) events (including all plus CV death) over 9.1±1.9 years. CT scans were performed to quantify AVC. Cox proportional hazards regressions and Harrell's C were used to examine AVC as event predictor in addition to risk factors and CAC. During follow-up, 138 (3.5%) subjects experienced coronary events, 101 (2.6%) had a stroke, and 257 (6.5%) experienced CVD events. In subjects with AVC>0 versus AVC=0 the incidence of coronary events was 8.0% versus 3.0% (pAVC scores (pAVC scores (3rd tertile) remained independently associated with coronary events (HR 2.21, 95% CI 1.28 to 3.81) and CVD events (HR 1.67, 95% CI 1.08 to 2.58). After further adjustment for CAC score, HRs were attenuated (coronary events 1.55, 95% CI 0.89 to 2.69; CVD events 1.29, 95% CI 0.83 to 2.00). When adding AVC to the model containing traditional risk factors and CAC, Harrell's C indices did not increase for coronary events (from 0.744 to 0.744) or CVD events (from 0.759 to 0.759). AVC is associated with incident coronary and CVD events independent of Framingham risk factors. However, AVC fails to improve cardiovascular event prediction over Framingham risk factors and CAC.

    The aim of this study was to determine whether markers of inflammation and coagulation are associated with short-term particulate matter exposure and predict major adverse cardiovascular events at 360 d in patients with acute coronary syndrome (ACS). We included 307 consecutive patients, and assessed the average concentrations of data on atmospheric pollution in ambient air and meteorological variables from 1 d up to 7 d prior to admission. In patients with ACS, the markers of endothelial activation and coagulation, but not black carbon exposure, are associated with major adverse cardiovascular events at one-year follow-up.

    Background Persons infected with human immunodeficiency virus (HIV) have increased rates of coronary artery disease (CAD). The relative contribution of genetic background, HIV-related factors, antiretroviral medications, and traditional risk factors to CAD has not been fully evaluated in the setting of HIV infection. Methods In the general population, 23 common single-nucleotide polymorphisms (SNPs) were shown to be associated with CAD through genome-wide association analysis. Using the Metabochip, we genotyped 1875 HIV-positive, white individuals enrolled in 24 HIV observational studies, including 571 participants with a first CAD event during the 9-year study period and 1304 controls matched on sex and cohort. Results A genetic risk score built from 23 CAD-associated SNPs contributed significantly to CAD (P = 2.9×10−4). In the final multivariable model, participants with an unfavorable genetic background (top genetic score quartile) had a CAD odds ratio (OR) of 1.47 (95% confidence interval [CI], 1.05–2.04). This effect was similar to hypertension (OR = 1.36; 95% CI, 1.06–1.73), hypercholesterolemia (OR = 1.51; 95% CI, 1.16–1.96), diabetes (OR = 1.66; 95% CI, 1.10–2.49), ≥1 year lopinavir exposure (OR = 1.36; 95% CI, 1.06–1.73), and current abacavir treatment (OR = 1.56; 95% CI, 1.17–2.07). The effect of the genetic risk score was additive to the effect of nongenetic CAD risk factors, and did not change after adjustment for family history of CAD. Conclusions In the setting of HIV infection, the effect of an unfavorable genetic background was similar to traditional CAD risk factors and certain adverse antiretroviral exposures. Genetic testing may provide prognostic information complementary to family history of CAD. PMID:23532479

    Full Text Available Abstract Background Adverse events are unintended patient injuries that arise from healthcare management resulting in disability, prolonged hospital stay or death. Adverse events that require intensive care admission imply a considerable financial burden to the healthcare system. The epidemiology of adverse events in Belgian hospitals has never been assessed systematically. Findings A multistage retrospective review study of patients requiring a transfer to a higher level of care will be conducted in six hospitals in the province of Limburg. Patient records are reviewed starting from January 2012 by a clinical team consisting of a research nurse, a physician and a clinical pharmacist. Besides the incidence and the level of causation and preventability, also the type of adverse events and their consequences (patient harm, mortality and length of stay will be assessed. Moreover, the adequacy of the patient records and quality/usefulness of the method of medical record review will be evaluated. Discussion This paper describes the rationale for a retrospective review study of adverse events that necessitate a higher level of care. More specifically, we are particularly interested in increasing our understanding in the preventability and root causes of these events in order to implement improvement strategies. Attention is paid to the strengths and limitations of the study design.

    Lyubov Chaykovska

    Full Text Available Vitamin-D-binding protein (VDBP is a low molecular weight protein that is filtered through the glomerulus as a 25-(OH vitamin D 3/VDBP complex. In the normal kidney VDBP is reabsorbed and catabolized by proximal tubule epithelial cells reducing the urinary excretion to trace amounts. Acute tubular injury is expected to result in urinary VDBP loss. The purpose of our study was to explore the potential role of urinary VDBP as a biomarker of an acute renal damage.We included 314 patients with diabetes mellitus or mild renal impairment undergoing coronary angiography and collected blood and urine before and 24 hours after the CM application. Patients were followed for 90 days for the composite endpoint major adverse renal events (MARE: need for dialysis, doubling of serum creatinine after 90 days, unplanned emergency rehospitalization or death.Increased urine VDBP concentration 24 hours after contrast media exposure was predictive for dialysis need (no dialysis: 113.06 ± 299.61 ng/ml, n = 303; need for dialysis: 613.07 ± 700.45 ng/ml, n = 11, Mean ± SD, p<0.001, death (no death during follow-up: 121.41 ± 324.45 ng/ml, n = 306; death during follow-up: 522.01 ± 521.86 ng/ml, n = 8; Mean ± SD, p<0.003 and MARE (no MARE: 112.08 ± 302.00 ng/ml, n = 298; MARE: 506.16 ± 624.61 ng/ml, n = 16, Mean ± SD, p<0.001 during the follow-up of 90 days after contrast media exposure. Correction of urine VDBP concentrations for creatinine excretion confirmed its predictive value and was consistent with increased levels of urinary Kidney Injury Molecule-1 (KIM-1 and baseline plasma creatinine in patients with above mentioned complications. The impact of urinary VDBP and KIM-1 on MARE was independent of known CIN risk factors such as anemia, preexisting renal failure, preexisting heart failure, and diabetes.Urinary VDBP is a promising novel biomarker of major contrast induced nephropathy-associated events 90 days after contrast media exposure.

    Obstructive sleep apnea (OSA) is associated with bad cardiovascular outcomes and a high prevalence of anxiety and depression. This study investigated the effects of continuous positive airway pressure (CPAP) on the severity of anxiety and depression in OSA patients with or without coronary artery disease (CAD) and on the rate of cardio- and cerebro-vascular events in those with OSA and CAD. This prospective study included patients with moderate-to-severe OSA, with or without a recent diagnosis of CAD; all were started on CPAP therapy. Patients completed the Chinese versions of the Beck Anxiety Inventory (BAI) and Beck Depression Inventory-II (BDI-II) at baseline and after 6-month follow-up. The occurrence of major adverse cardiac and cerebrovascular events (MACCE) was assessed every 3 months up to 1 year. BAI scores decreased from 8.5 ± 8.4 at baseline to 5.4 ± 6.9 at 6 months in CPAP-compliant OSA patients without CAD ( P < 0.05). BAI scores also decreased from 20.7 ± 14.9 to 16.1 ± 14.5 in CPAP-compliant OSA patients with CAD. BDI-II scores decreased in CPAP-compliant OSA patients without CAD (from 11.1 ± 10.7 at baseline to 6.6 ± 9.5 at 6 months) and in CPAP-compliant OSA patients with CAD (from 20.4 ± 14.3 to 15.9 ± 7.3). In addition, there was a large effect size (ES) of BAI and BDI in 6-month CPAP treatment of OSA patients with CAD and a large ES in those with OSA under CPAP treatment. In OSA patients with CAD, the occurrence of MACCE was significantly lower in CPAP-compliant patients than that in CPAP noncompliant patients (11% in CPAP compliant and 50% in noncompliant; P < 0.05). CPAP improved anxiety and depression in OSA patients regardless of CAD. In OSA patients with CAD, CPAP-compliant patients had a lower 1-year rate of MACCE than CPAP-noncompliant patients.

    Objectives To establish an accurate and comprehensive injury incidence registry of all rugby union-related catastrophic events in South Africa between 2008 and 2011. An additional aim was to investigate correlates associated with these injuries. Design Prospective. Setting The South African amateur and professional rugby-playing population. Participants An estimated 529 483 Junior and 121 663 Senior rugby union (‘rugby’) players (population at risk). Outcome measures Annual average incidences of rugby-related catastrophic injuries by type (cardiac events, traumatic brain and acute spinal cord injuries (ASCIs)) and outcome (full recoveries—fatalities). Playing level (junior and senior levels), position and event (phase of play) were also assessed. Results The average annual incidence of ASCIs and Traumatic Brain Injuries combined was 2.00 per 100 000 players (95% CI 0.91 to 3.08) from 2008 to 2011. The incidence of ASCIs with permanent outcomes was significantly higher at the Senior level (4.52 per 100 000 players, 95% CI 0.74 to 8.30) than the Junior level (0.24 per 100 000 players, 95% CI 0 to 0.65) during this period. The hooker position was associated with 46% (n=12 of 26) of all permanent ASCI outcomes, the majority of which (83%) occurred during the scrum phase of play. Conclusions The incidence of rugby-related catastrophic injuries in South Africa between 2008 and 2011 is comparable to that of other countries and to most other collision sports. The higher incidence rate of permanent ASCIs at the Senior level could be related to the different law variations or characteristics (eg, less regular training) compared with the Junior level. The hooker and scrum were associated with high proportions of permanent ASCIs. The BokSmart injury prevention programme should focus efforts on these areas (Senior level, hooker and scrum) and use this study as a reference point for the evaluation of the effectiveness of the programme.

    Full Text Available Abstract Background Objective data on the incidence and pattern of adverse events after orthopaedic surgical procedures remain scarce, secondary to the reluctance for encompassing reporting of surgical complications. The aim of this study was to analyze the nature of adverse events after orthopaedic surgery reported to a national database for patient claims in Sweden. Methods In this retrospective review data from two Swedish national databases during a 4-year period were analyzed. We used the "County Councils' Mutual Insurance Company", a national no-fault insurance system for patient claims, and the "National Patient Register at the National Board of Health and Welfare". Results A total of 6,029 patient claims filed after orthopaedic surgery were assessed during the study period. Of those, 3,336 (55% were determined to be adverse events, which received financial compensation. Hospital-acquired infections and sepsis were the most common causes of adverse events (n = 741; 22%. The surgical procedure that caused the highest rate of adverse events was "decompression of spinal cord and nerve roots" (code ABC**, with 168 adverse events of 17,507 hospitals discharges (1%. One in five (36 of 168; 21.4% injured patient was seriously disabled or died. Conclusions We conclude that patients undergoing spinal surgery run the highest risk of being severely injured and that these patients also experienced a high degree of serious disability. The most common adverse event was related to hospital acquired infections. Claims data obtained in a no-fault system have a high potential for identifying adverse events and learning from them.

    Up to 25% of patients with ST elevation myocardial infarction (STEMI) have ST segment re-elevation after initial regression post-reperfusion and there are few data regarding its prognostic significance.Methods and Results:A standard 12-lead electrocardiogram (ECG) was recorded in 662 patients with anterior STEMI referred for primary percutaneous coronary intervention (PPCI). ECGs were recorded 60-90 min after PPCI and at discharge. ST segment re-elevation was defined as a ≥0.1-mV increase in STMax between the post-PPCI and discharge ECGs. Infarct size (assessed as creatine kinase [CK] peak), echocardiography at baseline and follow-up, and all-cause death and heart failure events at 1 year were assessed. In all, 128 patients (19%) had ST segment re-elevation. There was no difference between patients with and without re-elevation in infarct size (CK peak [mean±SD] 4,231±2,656 vs. 3,993±2,819 IU/L; P=0.402), left ventricular (LV) ejection fraction (50.7±11.6% vs. 52.2±10.8%; P=0.186), LV adverse remodeling (20.1±38.9% vs. 18.3±30.9%; P=0.631), or all-cause mortality and heart failure events (22 [19.8%] vs. 106 [19.2%]; P=0.887) at 1 year. Among anterior STEMI patients treated by PPCI, ST segment re-elevation was present in 19% and was not associated with increased infarct size or major adverse events at 1 year.

    Clopidogrel has become standard treatment after urgent percutaneous coronary revascularization. Due to its enhanced and irreversible platelet inhibition, patients undergoing urgent surgical revascularization have a higher risk of bleeding complications and transfusions. Therefore, the effect of preoperative continuous administration of clopidogrel on the incidence of hemorrhagic complications in patients undergoing off-pump coronary artery bypass surgery with acute coronary syndrome was evaluated. From March 2004 to September 2006, 172 patients with acute coronary syndrome underwent isolated off-pump coronary artery bypass surgery; 70 (40.7%) and 102 (59.3%) of these patients did or did not take clopidogrel before surgery respectively. Seventy patients in each group were matched using propensity scores and associations between preoperative continuous administration of clopidogrel and postoperative bleeding, hemostatic reoperation, blood products received, the need for multiple transfusions and early graft patency by coronary computed tomography were assessed. Univariate analysis showed the continuous clopidogrel group had similar levels of postoperative bleeding for 24 h (601.4±312.6 ml vs 637.2±452.4 ml, p=0.616) and rates of reexploration (1.4% vs 1.4%), perioperative blood transfusion (33.3% vs 34.3%, p>0.05) and platelet transfusion (2.9% vs 7.1%, p=0.44) compared with the non-continuous group. Preoperative continuous administration of clopidogrel did not increase the risk of hemorrhagic complications in patients with acute coronary syndrome undergoing isolated off-pump coronary artery bypass surgery. These findings indicate that surgery after clopidogrel treatment in patients with acute coronary syndrome should not be delayed until platelet function returns to normal because they may have a higher risk of recurrent myocardial ischemic events.

    English national injury data collection systems are restricted to hospitalisations and deaths. With recent linkage of a large primary care database, the Clinical Practice Research Datalink (CPRD), with secondary care and mortality data, we aimed to assess the utility of linked data for injury research and surveillance by examining recording patterns and comparing incidence of common injuries across data sources. The incidence of poisonings, fractures and burns was estimated for a cohort of 2 147 853 0-24 year olds using CPRD linked to Hospital Episode Statistics (HES) and Office for National Statistics (ONS) mortality data between 1997 and 2012. Time-based algorithms were developed to identify incident events, distinguishing between repeat follow-up records for the same injury and those for a new event. We identified 42 985 poisoning, 185 517 fracture and 36 719 burn events in linked CPRD-HES-ONS data; incidence rates were 41.9 per 10 000 person-years (95% CI 41.4 to 42.4), 180.8 (179.8-181.7) and 35.8 (35.4-36.1), respectively. Of the injuries, 22 628 (53%) poisonings, 139 662 (75%) fractures and 33 462 (91%) burns were only recorded within CPRD. Only 16% of deaths from poisoning (n=106) or fracture (n=58) recorded in ONS were recorded within CPRD and/or HES records. None of the 10 deaths from burns were recorded in CPRD or HES records. It is essential to use linked primary care, hospitalisation and deaths data to estimate injury burden, as many injury events are only captured within a single data source. Linked routinely collected data offer an immediate and affordable mechanism for injury surveillance and analyses of population-based injury epidemiology in England.

    Full Text Available Ultrasound non-invasive coronary artery imaging contributes to the diagnosis of ischemic heart disease (IHD in clinical practice. However, data of the prognostic value obtained from a complex analysis of contractility disorders and coronary blood flow parameters during exercise tests in the world literature are still not available. Aim. To develop risk models for adverse outcomes in patients with probable or definite IHD based on the results of a stress test with a noninvasive coronary blood flow study. Material and methods. Medical data of 689 patients with probable or definite IHD who underwent stress echocardiography with satisfactory visualization of the anterior interventricular artery (AIVA were included in the analysis. All patients had stress echocardiography on a horizontal bicycle ergometer. Registration of coronary blood flow in the middle third of the AIVA was performed at rest and at the peak of the load with calculation of the coronary reserve value. Further patient follow-up lasted 3 years. Models of further negative outcomes were developed on the basis of the stress echocardiography results and of coronary blood flow parameters. Results. Three models that take into account the factors associated with further mortality, mortality/myocardial infarction and sum of negative outcomes were developed in the study. These models divide a cohort of patients with probable or definite IHD into groups of low, medium and very high risks. Factors associated with the risk of death include: age >56 years, load power <100 W, breach of contractility in the blood supply zone of the circumflex artery initially and during exercise, the difference in blood flow velocities in the AIVA<10 cm/s, coronary reserve of AIVA<2. The risk model of death, taking into account these factors, suggests dividing patients into low-risk group if there are ≤2 factors (mortality 0.6% for 3 years, medium risk – from 2 to 4 factors (mortality 1.8%, high risk – ≥5

    Current studies found an incidence of 12-31% ventricular tachyarrhythmias and sudden cardiac death during cardiac pacing months or even years after pacemaker insertion. MADIT(12) and MUSTT(13) demonstrated that patients with poor LV function after Myocardial infarction (MI) showing non-sustained ventricular tachycardia (nsVT) and inducibility during electrophysiologic testing benefit from an ICD. The present study was dedicated to assess the global incidence of non-sustained ventricular arrhythmias in a general population of pacemaker patients. Special regard was on patients with a potential ICD indication, e.g. those matching the MADIT/MUSTT criteria. Two hundred and thirty-one patients (72 +/- 11 years; 134 men) with an indication for dual chamber pacing entered the study. In all patients pacemaker systems capable of automatic storing of intracardiac electrocardiograms were implanted (Pulsar, Discovery, Guidant). Follow-up time was 15 months after inclusion. In 54 (25.7%) of 210 patients with at least one follow-up, episodes of nsVT were documented by stored electrocardiograms (up to >30 beats, >200 b.p.m.). Multiple-up to nine-episodes of ventricular tachycardia were retrieved in 31 of these patients. Three out of 14 patients with an LVEF <40% after MI presented nsVT during the follow-up. One of these patients received an ICD. A significant number of pacemaker patients present with ventricular tachycardia. Intracardiac electrocardiograms and alert functions from pacemakers may enhance physicians' awareness of the patient's intrinsic arrhythmic profile and help uncover underlying mechanisms of arrhythmias by storing the initiation of the arrhythmia.

    Association between the use of hemostatic agents made from collagen/gelatin mixed with thrombin and thromboembolic events in patients undergoing tumor resection has been suggested. This study evaluates the relationship between flowable hemostatic matrix and deep vein thrombosis in a large cohort of patients treated for brain tumor removal. The authors conducted a retrospective, multicenter, clinical review of all craniotomies for tumor removal performed between 2013 and 2014. Patients were classified in three groups: group I (flowable gelatin hemostatic matrix with thrombin), group II (gelatin hemostatic without thrombin), and group III (classical hemostatic). A total of 932 patients were selected: tumor pathology included 441 gliomas, 296 meningiomas, and 195 metastases. Thromboembolic events were identified in 4.7% of patients in which gelatin matrix with thrombin was applied, in 8.4% of patients with gelatin matrix without thrombin, and in 3.6% of cases with classical methods of hemostasis. Patients with venous thromboembolism had an increased proportion of high-grade gliomas (7.2%). Patients receiving a greater dose than 10 ml gelatin hemostatic had a higher rate of thromboembolic events. Intracranial hematoma requiring reintervention occurred in 19 cases: 4.5% of cases of group III, while reoperation was performed in 1.3 and 1.6% of patients in which gelatin matrix with or without thrombin was applied. Gelatin matrix hemostat is an efficacious tool for neurosurgeons in cases of difficult intraoperative bleeding during cranial tumor surgery. This study may help to identify those patients at high risk for developing thromboembolism and to treat them accordingly.

    As part of its Single Technology Appraisal process, the National Institute for Health and Care Excellence (NICE) invited the company that manufactures rivaroxaban (Xarelto, Bayer) to submit evidence of the clinical and cost effectiveness of rivaroxaban for the prevention of adverse outcomes in patients after the acute management of acute coronary syndrome (ACS). The School of Health and Related Research Technology Appraisal Group at the University of Sheffield was commissioned to act as the independent Evidence Review Group (ERG). The ERG produced a critical review of the evidence for the clinical and cost effectiveness of the technology, based upon the company's submission to NICE. The evidence was derived mainly from a randomised, double-blind, phase III, placebo-controlled trial of rivaroxaban (either 2.5 or 5 mg twice daily) in patients with recent ACS [unstable angina, non-ST segment elevation myocardial infarction (NSTEMI) or ST segment elevation myocardial infarction (STEMI)]. In addition, all patients received antiplatelet therapy [aspirin alone or aspirin and a thienopyridine either as clopidogrel (approximately 99 %) or ticlopidine (approximately 1 %) according to national or local guidelines]. The higher dose of rivaroxaban (5 mg twice daily) did not form part of the marketing authorisation. A post hoc subgroup analysis of the licensed patients who had ACS with elevated cardiac biomarkers (that is, patients with STEMI and NSTEMI) without prior stroke or transient ischaemic stroke showed that compared with standard care, the addition of rivaroxaban (2.5 mg twice daily) to existing antiplatelet therapy reduced the composite endpoint of cardiovascular mortality, myocardial infarction or stroke, but increased the risk of major bleeding and intracranial haemorrhage. However, there were a number of limitations in the evidence base that warrant caution in its interpretation. In particular, the evidence may be confounded because of the post hoc subgroup

    The French nuclear safety regulations lay down the action to be taken in the event of an incident or accident involving the types of radiological hazard that could arise in a nuclear installation or during the transport of radioactive material. The organization established for this purpose is designed to ensure that the technical measures taken by the authorities responsible for nuclear safety, radiation protection, public order and public safety are fully effective. The Interministerial Nuclear Safety Committee (Comite interministeriel de la securite nucleaire), which reports to the Prime Minister, co-ordinates the measures taken by the public authorities. The public authorities and the operators together organize exercises designed to verify the whole complex of measures foreseen in the event of an incident or accident. These exercises, which have been carried out in a systematic manner in France for some years, are based on scenarios which are as realistic as possible and enable the following objectives to be achieved: (1) analysis of the crisis apparatus (ORSECRAD plans, individual intervention plans, information conventions); (2) uncovering gaps or inadequacies; (3) arrangements for interchange of information between the various participants whose responsibilities involve them in the emergency; and (4) allowance for the information requirements of the media and the population. The information drawn from these exercises enables the various procedures to be improved step by step. (author)

    International Nuclear Information System (INIS)

    2012-01-01

    After the Fukushima Daiichi accident on March 11 th , 2011, the Swiss Federal Nuclear Safety Inspectorate (ENSI) conducted various analyses in order to understand the sequence of events and the contributing factors from both a human as well as an organizational point of view. This analysis considers reports published by TEPCO, the operator of the Fukushima power plants, the Japanese Authorities and IAEA. The deepening of the analysis of the human and organizational aspects became necessary as the accident and its causes are very complex. This complexity is not only the result of technical aspects, but it is also due to the interactions between technical, organizational and human aspects. It is to be considered that additional analyses will be required to exactly understand the physical, organizational and human processes involved. One has to keep in mind the tremendous dimension of the earthquake and the tsunami, as well as the courage and devotedness shown by the actors involved, especially the workers of the Fukushima plants. They had to treat the dramatic issues of the accident, which hit three reactor blocks, and they had to react on the spot to the catastrophic situation with many subsequent earthquakes and, sometimes, without news about their own families. It is necessary to understand the organizational weaknesses with respect to the protection of the plant against the danger of a very large tsunami and the management of a serious accident, in order to learn the necessary lessons. The weaknesses can only be explained by a thorough analysis of the situation which, at the same time, takes the technical environment into account as well as organizational aspects of the accident. The present report considers important event data which are necessary for the understanding of the situation that the various organizations and persons had to master. The role of the organizations in Tokyo and in the Fukushima prefecture is also analyzed. The Fukushima accident is the

    We sought to determine the prevalence, predictors, and clinical impact of target lesion calcification in patients undergoing percutaneous coronary intervention (PCI) with newer generation drug-eluting stents (DES) and devices. Coronary calcification is independently associated with adverse outcomes following PCI. While newer DES and contemporary devices are considered safer and more efficacious, their influence on outcomes following PCI of heavily calcified lesions is unknown. We performed a retrospective analysis of a large, multiethnic cohort of patients undergoing PCI with new generation DES at an academic center between 2009 and 2013. Coronary calcification was qualitatively assessed as none/mild, moderate, or severe. Independent demographic, clinical, and anatomic predictors of moderate/severe calcification were identified using logistic regression. Associations between coronary calcification and 1-year MACE (death, myocardial infarction, or target vessel revascularization) were examined using Cox modeling. Compared to patients with none/mild (n = 10,180; 82.0%), those with moderate (n = 1,271; 10.0%) or severe (n = 994; 8.0%) calcification were older, more often Caucasian, had more complex target lesions, and worse renal function. The strongest demographic, clinical, and anatomic correlates of moderate/severe calcification were age, Caucasian race, renal dysfunction, lesion length, and left main location. Unadjusted MACE rates among those with none/mild, moderate, and severe calcification were 8.3, 14.6, and 17.8%, respectively (P < 0.001). After multivariable adjustment, the hazard ratio (95% CI) for MACE associated with moderate or severe coronary calcification was 1.63. Target lesion calcification remains independently associated with adverse outcomes in patients treated with newer generation DES and modern devices. © 2017 Wiley Periodicals, Inc.

    Kaplan-Meier survival analysis overestimates cumulative incidence in competing risks (CRs) settings. The extent of overestimation (or its clinical significance) has been questioned, and CRs methods are infrequently used. This meta-analysis compares the Kaplan-Meier method to the cumulative incidence function (CIF), a CRs method. We searched MEDLINE, EMBASE, BIOSIS Previews, Web of Science (1992-2016), and article bibliographies for studies estimating cumulative incidence using the Kaplan-Meier method and CIF. For studies with sufficient data, we calculated pooled risk ratios (RRs) comparing Kaplan-Meier and CIF estimates using DerSimonian and Laird random effects models. We performed stratified meta-analyses by clinical area, rate of CRs (CRs/events of interest), and follow-up time. Of 2,192 identified abstracts, we included 77 studies in the systematic review and meta-analyzed 55. The pooled RR demonstrated the Kaplan-Meier estimate was 1.41 [95% confidence interval (CI): 1.36, 1.47] times higher than the CIF. Overestimation was highest among studies with high rates of CRs [RR = 2.36 (95% CI: 1.79, 3.12)], studies related to hepatology [RR = 2.60 (95% CI: 2.12, 3.19)], and obstetrics and gynecology [RR = 1.84 (95% CI: 1.52, 2.23)]. The Kaplan-Meier method overestimated the cumulative incidence across 10 clinical areas. Using CRs methods will ensure accurate results inform clinical and policy decisions.

    Full Text Available Abstract Background Breast cancer (BrCa is the most commonly diagnosed cancer among women in the industrialized world. More than half of women presenting with metastatic BrCa develop bone metastases. Bone metastases increase the risk of skeletal-related events (SREs, defined as pathological fractures, spinal cord compression, bone pain requiring palliative radiotherapy, and orthopaedic surgery. Both bone metastases and SREs are associated with unfavorable prognosis and greatly affect quality of life. Few epidemiological data exist on SREs after primary diagnosis of BrCa and subsequent bone metastasis. We therefore estimated the incidence of bone metastases and SREs in newly-diagnosed BrCa patients in Denmark from 1999 through 2007. Methods We estimated the overall and annual incidence of bone metastases and SREs in newly-diagnosed breast cancer patients in Denmark from January 1, 1999 to December 31, 2007 using the Danish National Patient Registry (DNPR, which covers all Danish hospitals. We estimated the cumulative incidence of bone metastases and SREs and associated 95% confidence intervals (CI using the Kaplan-Meier method. Results Of the 35,912 BrCa patients, 178 (0.5% presented with bone metastases at the time of primary breast cancer diagnosis, and of these, 77 (43.2% developed an SRE during follow up. A total of 1,272 of 35,690 (3.6% BrCa patients without bone metastases at diagnosis developed bone metastases during a median follow-up time of 3.4 years. Among these patients, 590 (46.4% subsequently developed an SRE during a median follow-up time of 0.7 years. Incidence rates of bone metastases were highest the first year after the primary BrCa diagnosis, particularly among patients with advanced BrCa at diagnosis. Similarly, incidence rates of a first SRE was highest the first year after first diagnosis of a bone metastasis. Conclusions The high incidence of SREs following the first year after first diagnosis of a bone metastasis

    Sexual assault in the United States is an important public health concern. Using prospective longitudinal methods and responses from 217 community men, we examined whether background characteristics predicted subsequent sexual aggression (SA) perpetration during a 3-month follow-up period. We also examined event-specific characteristics of reported SA occurrences. Consistent with predictions, SA perpetration history, aggressive and impulsive personality traits, rape myth attitudes, and alcohol expectancies predicted SA (both non- and alcohol-involved) at follow-up. In addition, alcohol-involved assaults occurred more often with casual (vs. steady) partners but were more likely to involve condom use with casual (vs. steady) partners. Results suggest important avenues for future research and SA prevention efforts. © The Author(s) 2015.

    The Mediterranean diet has been reported to be inversely associated with incident metabolic syndrome (MetSyn) among older adults; however, this association has not been studied in young African American and white adults. The objective of the present study was to evaluate the association of a modified Mediterranean diet (mMedDiet) score with the 25-year incidence of the MetSyn in 4713 African American and white adults enrolled in the Coronary Artery Risk Development in Young Adults (CARDIA) study. A diet history questionnaire was used to assess dietary intake at baseline, year 7 and year 20 and a mMedDiet score was created. Cardiovascular risk factors were measured at multiple examinations over 25 years. The MetSyn was defined according to the National Cholesterol Education Program Adult Treatment Panel III (ATP III) criteria. Cox proportional-hazards regression analysis was use to evaluate associations for incident MetSyn across the mMedDiet score categories adjusting for demographic characteristics, lifestyle factors and BMI. Higher mMedDiet scores represented adherence to a dietary pattern rich in fruit, vegetables, whole grains, nuts and fish, but poor in red and processed meat and snack foods. The incidence of MetSyn components (abdominal obesity, elevated TAG concentrations and low HDL-cholesterol concentrations) was lower in those with higher mMedDiet scores than in those with lower scores. Furthermore, the incidence of the MetSyn was lower across the five mMedDiet score categories; the hazard ratios and 95 % CI from category 1 to category 5 were 1·0; 0·94 (0·76, 1·15); 0·84 (0·68, 1·04); 0·73 (0·58, 0·92); and 0·72 (0·54, 0·96), respectively (P trend= 0·005). These findings suggest that the risk of developing the MetSyn is lower when consuming a diet rich in fruit, vegetables, whole grains, nuts and fish.

    Atherosclerosis and osteoporosis are chronic diseases that progress with age, and studies suggest aortic calcification, an indicator of atherosclerosis, is inversely associated with bone mineral density (BMD). The osteoprotegerin (OPG)/receptor activator of NF-κB (RANK)/RANK ligand (RANKL) system has been proposed as a shared regulatory system for bone and vasculature. Denosumab (DMAb), a monoclonal antibody against RANKL, improved BMD and reduced fracture risk in the Fracture Reduction Evaluation of Denosumab in Osteoporosis Every 6 Months (FREEDOM) trial. We evaluated whether or not treatment with DMAb influenced progression of aortic calcification (AC) and incidence of cardiovascular (CV) adverse events. We included 2363 postmenopausal women with osteoporosis (1142 placebo, 1221 DMAb), selected from 7808 participants in the FREEDOM trial (3906 placebo, 3902 DMAb), at high risk of CV events according to modified Raloxifene Use for the Heart (RUTH) criteria. CV adverse events were reported by participants. AC scores were assessed using a semiquantitative method from lateral spine X-rays. Change in AC score from baseline to 12 (n = 1377), 24 (n = 1231), and 36 months (n = 1045) was calculated as AC score at follow-up minus AC score at baseline. AC progression was defined as change in AC score >0. Baseline characteristics, CV risk factors, and AC scores were similar between treatment groups. Mean age of participants was 74 years (range, 60-90), 88% were white, and 77% had AC score >0 at baseline. Frequency of AC progression over 3 years did not differ between women in placebo (22%) and DMAb (22%) groups (p = 0.98). AC progression did not differ between treatment groups when analyzed by baseline estimated glomerular filtration rate or by baseline AC scores. Frequency of CV adverse events did not differ between placebo (40%) and DMAb (38%) groups (p = 0.26). In conclusion, DMAb treatment had no effect on progression of AC or incidence of CV

    Full Text Available Background Myocardial fibrosis (MF is a risk factor for poor prognosis in dilated cardiomyopathy (DCM. Late gadolinium enhancement (LGE of the myocardium on cardiac magnetic resonance (CMR represents MF. We examined whether the LGE amount increases the incidence of adverse cardiovascular events in patients with stage C or D heart failure (HF. Methods Eighty-four consecutive patients with stage C or D HF, either ischemic or non-ischemic, were enrolled. Comprehensive clinical and CMR evaluations were performed. All patients were followed up for a composite endpoint of cardiovascular death, heart transplantation, and cardiac resynchronization therapy with defibrillator (CRT-D.Results LGE was present in 79.7% of the end-stage HF patients. LGE distribution patterns were mid-wall, epi-myocardial, endo-myocardial, and the morphological patterns were patchy, transmural, and diffuse. During the average follow-up of 544 days, 13 (15.5% patients had endpoint events: 7 patients cardiac death, 2 patients heart transplantation, and 4 patients underwent CRT-D implantation. On univariate analysis, LGE quantification on cardiac magnetic resonance, blood urine nitrogen, QRS duration on electrocardiogram, left ventricular end-diastolic diameter (LVEDD and left ventricular end-diastolic volume (LVEDV on CMR had the strongest associations with the composite endpoint events. However, on multivariate analysis for both Model I (after adjusting for age, sex, and body mass index and Model II (after adjusting for age, sex, BMI, renal function, QRS duration and atrial fibrillation on electrocardiogram, the etiology of HF, LVEF, CMR-LVEDD and CMR-LVEDV, LGE amount was a significant risk factor for composite endpoint events (Model I 6SD HR 1.037, 95%CI 1.005-1.071, p=0.022; Model II 6SD HR 1.045, 95%CI 1.001-1.084, p=0.022. Conclusion LGE amount from high-scale threshold on CMR increased the incidence of adverse cardiovascular events for patients in either stage C or D HF.

    2012-06-01

    Abstract Adequate risk assessment for cardiovascular disease (CVD) is essential as a guide to initiate drug treatment. Current methods based on traditional risk factors could be improved considerably. Although brachial flow-mediated dilation (FMD) predicts subsequent cardiovascular events, its predictive value on top of traditional risk factors is unknown. We performed a systematic review to evaluate the incremental predictive value of FMD on top of traditional risk factors in asymptomatic individuals. Using PubMed and reference tracking, three studies were identified that reported on the incremental value of FMD using change in the area under the curve (AUC). Two large cohort studies found no improvement in AUC when FMD was added to traditional risk prediction models, whereas one small case-control study found an improvement. One study used the net reclassification improvement (NRI) to assess whether FMD measurement leads to correct risk stratification in risk categories. Although this study did not find an improvement in AUC, the NRI was statistically significant. Based on the reclassification results of this study, FMD measurement might be helpful in risk prediction. Evidence supporting the use of FMD measurement in clinical practice for risk stratification for CVD on top of traditional risk factors is limited, and future studies are needed.

    Diabetic patients have been associated with poor procedural and long term outcome if they were treated either with percutaneous coronary interventions or coronary artery bypass surgery. Recently several randomized clinical trials (RCT) in this subset of patients have been published showing a greater incidence of major adverse cardiovascular events, death/myocardial infarction/stroke, if they were treated with first generation drug eluting stents (DES) which was not observed previously in the bare metal stent era. However, almost simultaneously with this data, several RCT demonstrated better safety profile with new generation DES including biocompatible polymers, biodegradable polymers and lately complete absorbable DES, all of them showed reduction in adverse cardiac events compared to 1st generation DES in patients with diabetes. In this editorial we review the old and new randomized data in diabetic patients and conclude that there are many unresolved issues to make a definitive statement regarding which is the best revascularization preference in diabetic patients and the measured final efficacy of PCI and CABG will not be reached until the arrival of RCT using next generation DES, including complete absorbable scaffolds. - Highlights: • Diabetic patients have been associated with poor procedural and long term outcome if they were treated either with percutaneous coronary interventions or coronary artery bypass surgery.

    The aim of the present study was to determine the early and long-term outcomes of coronary artery bypass grafting in patients with acute coronary syndrome and stable angina pectoris. From September 2004 to September 2011, 382 patients with acute coronary syndrome (unstable angina pectoris and non-ST-segment elevation myocardial infarction) and 851 patients with stable angina pectoris underwent first-time isolated coronary artery bypass grafting at our institute. The early and long-term outcomes were compared between the 2 groups. Patients with acute coronary syndrome were older, were more likely to be women, had a smaller body surface area, and were more likely to have left main coronary artery disease. In both groups, bilateral internal thoracic artery grafts were used in approximately 89% of the patients, and off-pump techniques in approximately 97% of the patients. The acute coronary syndrome group had a greater operative death rate (2.6% vs 0.1%) and a greater incidence of low output syndrome (3.1% vs 1.2%) and hemodialysis requirement (2.9% vs 1.1%). Multivariate regression analysis demonstrated that age, acute coronary syndrome, lower ejection fraction, and higher creatinine level before surgery were independent predictors of operative death. However, among the hospital survivors, no differences were seen in freedom from all death (85.4% ± 2.5% vs 87.7% ± 2.0%), cardiac death (97.4% ± 0.9% vs 96.5% ± 0.9%), or major adverse cardiac and cerebrovascular events (78.0% ± 2.9% vs 78.1% ± 2.3%) at 7 years between the patients with acute coronary syndrome and stable angina pectoris. Although acute coronary syndrome is an independent predictor of early mortality in patients undergoing coronary artery bypass grafting, the long-term outcomes after surgery were similar between patients with acute coronary syndrome and stable angina pectoris who survived the early postoperative period.

    Objective: To evaluate the long-term effect of coronary stenting in young coronary artery diseased patients ( 45) undergoing coronary stenting were chosen randomly as the control group. Comparison the general characteristics, coronary angiographies, interventional and follow-up information between the two groups was undertaken. Results: Comparing with the control group, the young group patients presented much more myocardial infarctions (68% vs 35%, P<0.05) and single-vessel disease (83% vs 57%, P=0.001). Complete revascularization was achieved in 95% patients in the young group (95% vs control 78%, P=0.004). With a mean 67 ± 9 months follow-up, recurrent angina and readmission rate were higher in the young group, as well as the incidence of MACE. Repeat CAG revealed much more de novo lesions in the young group (44% vs 11%, P=0.02) and higher rate of re-stenting. Conclusions: Due to the high rate of complete circulatory reconstruction in young patients, the postprocedural events are probably caused by new coronary arterial lesions; therefore coronary stenting should be regarded as the primary choice of treatment.

    Although elderly people has a higher incidence of coronary heart disease, this group is seldom included in clinical trials. Studies performed in Spain on elderly coronary heart disease patients have been conducted in hospital settings. The aim of our study was to analyse wether the management of coronary heart disease patients over 64 years of age cared by family physicians differed from that of the rest. Cross-sectional multicentre study embedded in a clinical trial on 1,022 patients with stable coronary heart disease in which socio-demographic variables, comorbidity, treatment and cardiovascular risk- factor control were collected. Mean age was 64 10, 74.0% were men and 53.8% of subjects were over 64 years. Patients over 64 years had a greater cardiovascular comorbidity (87.7 vs 82.6%; p = 0.002) and received lower number of drugs than the rest in the prevention of recurrences (60.4 vs 70.9%; p < 0.001). Probability to receive less than two drugs on secondary prevention by subjects over 64 years was 0.45 (95% CI, 0.30-0.68) despite comorbidity, sex and cardiovascular risk profile.Conclusions. Coronary heart disease patients over 64 years receive less drugs for coronary event recurrence prevention than their younger counterparts despite their worse cardiovascular risk profile.

    Percutaneous coronary intervention (PCI) has been extensively applied to repair the forward flow of diseased coronary artery and can achieve significant curative results. However, some patients with acute myocardial infarction (AMI) develop non-perfusion or poor perfusion of cardiac muscle tissue after PCI, which increases the incidence of cardiovascular events and the death rate. PCI can dredge narrowed or infarct-related artery (IRA) and thus induce full reperfusion of ischemic myocardium. It is found in practice that some cases of AMI still have no perfusion or poor perfusion in myocardial tissue even though coronary angiography suggests opened coronary artery after PCI, which increases the incidence of vascular events and mortality. Therefore, to explore the detailed mechanism of PCI in treating coronary microcirculation of patients with stable angina pectoris, we selected 140 patients with stable angina pectoris for PCI, observing the index of microcirculatory resistance (IMR) of descending branch and changes of myocardial injury markers and left ventricular systolic function, and made a subgroup analysis based on the correlation between clinical indexes, IMR and other variables of diabetic and non-diabetic patients, PCI-related and non-PCI-related myocardial infarction patients. The results suggest that IMR of anterior descending branch after PCI was higher compared to that before PCI, and the difference was significant (P less than 0.05); creatine kinase-MB (CK-MB), myohemoglobin and high sensitive troponin T were all increased after PCI, and the difference was also significant (P less than 0.05); brain natriuretic peptide (BNP) level became higher after PCI, with significant difference (P less than 0.05); left ventricular ejection fraction (LVEF) declined after PCI, and the difference before and after PCI was statistically significant (P less than 0.05). Moreover, subgroup analysis results of the three groups all demonstrated statistically significant

  10. Computer simulation of nuclear pollutant diffusion from Shimane nuclear power plants and development of an evacuation strategy in the event of a nuclear incident

    Beginning from Tohoku (northeastern) Earthquake on March 11, an accident at the Fukushima Dai-ichi Nuclear Power Plant resulted in a substantial release of radioactivity to the environment. The accident forced a large number of residents to evacuate from surrounding areas. Moreover, the nuclear incident was life-threatening for the elderly and for people with serious illnesses who were confined in hospital or nursing homes. Strikingly, the causes of death were not directly attributed to radiation exposure but to problems encountered during evacuation. Using nuclear diffusion data from the Fukushima incident, we simulated nuclear pollutant dispersion using computer software A2C in an area of Tottori and Shimane Prefectures surrounding the Shimane Nuclear Power Plant. We generated a model for the spread of nuclear pollutants around the Emergency Planning Zone, id est (i.e.) EPZ. From these findings, we proposed evacuation strategies for residents near the power plant to ensure a safe and reliable escape from nuclear pollutants. Our recommendations include: immediate evacuation from PAZ area (within 5 km), securing indoor shelter in the area of the UPZ (from 5 km to 30 km) and preparations to evacuate further outwards from the nuclear plant site, daytime evacuation within a 30 km area after considering wind direction and velocity, and preparation of a planned evacuation strategy that identifies secure facilities for weaker people in the event of a disaster.

    To determine incidence rates (IRs) and potential risk factors for owner-reported adverse events (AEs) following vaccination of dogs that did or did not receive a Leptospira vaccine. Observational, retrospective cohort study. 130,557 dogs. Electronic records of mobile veterinary clinics from June 2012 to March 2013 were searched to identify dogs that received ≥ 1 vaccine in a given visit. Signalment data, vaccinations received, medications administered, and owner-reported clinical signs consistent with AEs that developed ≤ 5 days after vaccination were recorded. Associations between potential risk factors and owner-reported AEs were evaluated by logistic regression analysis. The IR/10,000 dogs for owner-reported postvaccination AEs was 26.3 (95% CI, 23.6 to 29.2), whereas that for dogs that received a Leptospira vaccine alone or with other vaccines was 53.0 (95% CI, 42.8 to 64.9). Significant factors for increasing or decreasing risk of AEs were as follows: receiving a Leptospira vaccine (adjusted OR, 2.13), age at vaccination 1 to dogs), and IRs for these events did not differ significantly between dogs vaccinated with or without a Leptospira component. The overall IR for owner-reported postvaccination AEs was low. Results suggested vaccination against Leptospira (an organism that can cause fatal disease) is safe in the majority of cases, slightly increasing the risk of owner-reported AEs but not associated with a significant increase in hypersensitivity reactions, compared with other vaccinations administered.

    Natriuretic peptides are recognized as important predictors of cardiovascular events in patients with heart failure, but less is known about their prognostic importance in patients with acute coronary syndrome. We sought to determine whether B-type natriuretic peptide (BNP) and N-terminal prohormone B-type natriuretic peptide (NT-proBNP) could enhance risk prediction of a broad range of cardiovascular outcomes in patients with acute coronary syndrome and type 2 diabetes mellitus. Patients with a recent acute coronary syndrome and type 2 diabetes mellitus were prospectively enrolled in the ELIXA trial (n=5525, follow-up time 26 months). Best risk models were constructed from relevant baseline variables with and without BNP/NT-proBNP. C statistics, Net Reclassification Index, and Integrated Discrimination Index were analyzed to estimate the value of adding BNP or NT-proBNP to best risk models. Overall, BNP and NT-proBNP were the most important predictors of all outcomes examined, irrespective of history of heart failure or any prior cardiovascular disease. BNP significantly improved C statistics when added to risk models for each outcome examined, the strongest increments being in death (0.77-0.82, P type 2 diabetes mellitus, BNP and NT-proBNP were powerful predictors of cardiovascular outcomes beyond heart failure and death, ie, were also predictive of MI and stroke. Natriuretic peptides added as much predictive information about death as all other conventional variables combined. URL: http://www.clinicaltrials.gov.

    A study was made of the incidence of certain types of disease among Seventh-day Adventists, a religious group of special interest because they refrain from smoking and drinking. Epidermoid cancer of the lung, previously shown to be related to smoking, was 10 times less common among Seventh-day Adventists than among the general population, even among those Seventh-day Adventists living in the Los Angeles area where all are exposed to smog. Similarly, cancers of the mouth, larynx, and esophagus, previously shown to be related not only to smoking but also to heavy drinking, were at least 10 times less common among Seventh-day Adventist men than among men of the general population. All other types of cancer, with the exception of cancer of the bladder and cervix, occurred among Seventh-day Adventists with the same frequency as in the general population. The latter occurred slightly less than in the general population. Myocardial infarction in Seventh-day Adventist males was less frequent and occurred at a later age than among males in the general population; while the age distribution of the disease among the Seventh-day Adventist females was similar to that of females in the general population.

    The main objective of this study is to describe incidence rates of low-speed vehicle run-over (LSVRO) events among children aged 0-14 years residing in Queensland from 1999 to 2009. A second objective was to describe the associated patterns of injury, with respect to gender, age group, severity, characteristics (host, vehicle and environment), and trends over time in relation to geographical remoteness. Final results are hoped to inform prevention policies. In this statewide, retrospective, population-based study, data were collected on LSVRO events that occurred among children aged 0-14 years in Queensland from 1999 to 2009 from all relevant data sources across the continuum of care, and manually linked to obtain the most comprehensive estimate possible of the magnitude and nature of LSVRO events to date. Crude incidence rates were calculated separately for males and females, for fatal events, non-fatal events (hospital admissions and non-admissions, respectively), and for all LSVRO events, for each area of geographical remoteness (major cities, inner regional, outer regional, remote/very remote). Relative risks and 95% confidence interval were calculated, and trends over time were examined. Data on host, injury and event characteristics were also obtained to investigate whether these characteristics varied between areas of remoteness. Incidence rates were lowest among children (0-14 years) living in major cities (13.8/100 000/annum, with the highest recorded incidence in outer regional areas (incidence rate =42.5/100 000/annum). Incidence rates were higher for children residing outside major cities for both males and females, for every age group, for each of the 11 years of the study, and consequences of LSVRO events were worse. Young children aged 0-4 years were identified as those most at risk for these events, regardless of geographical location. Differences were observed as a function of remoteness category in relation to injury characteristics (eg injury

    The prognostic impact of β-blockers (BB) in acute coronary syndrome (ACS) patients without heart failure (HF) or left ventricular dysfunction is controversial, especially in the postreperfusion era. We sought to determine whether a BB therapy before admission for ACS has a favorable in-hospital outcome in patients without HF, and whether they also reduce 12-month mortality if still prescribed on discharge. The GULF-RACE 2 (Gulf Registry of Acute Coronary Events-2) is a prospective multicenter study of ACS in 6 Middle Eastern countries. We studied in-hospital cardiovascular events in patients hospitalized for ACS without HF in relation to BB on admission, and 1-year mortality in relation to BB on discharge. Among the 7903 participants, 7407 did not have HF, of whom 5937 (80.15%) patients were on BB. Patients on BB tended to be older and have more comorbidities. However, they had a lower risk of in-hospital mortality, mitral regurgitation, HF, cardiogenic shock, and ventricular tachycardia/ventricular fibrillation. Furthermore, 4208 patients were discharged alive and had an ejection fraction ≥40%. Among those, 84.1% had a BB prescription. At 12 months, they also had a reduced risk of mortality as compared with the non-BB group. Even after correcting for confounding factors in 2 different models, in-hospital and 12-month mortality risk was still lower in the BB group. In this cohort of ACS, BB therapy before admission for ACS is associated with decreased in-hospital mortality and major cardiovascular events, and 1-year mortality in patients without HF or left ventricular dysfunction if still prescribed on discharge. © 2017 The Authors.

    To investigate whether adjunctive eslicarbazepine acetate (ESL) could lead to exacerbation of seizures in some patients. Post-hoc analysis of data pooled from three Phase III trials of adjunctive ESL (studies 301, 302, and 304) for refractory partial-onset seizures (POS). Following an 8-week baseline period, patients were randomized to receive placebo or ESL 400, 800, or 1,200 mg once daily (2-week titration, 12-week maintenance, 2-4 week tapering-off periods). Patient seizure diary data and seizure treatment-emergent adverse event (TEAE) reports were pooled for analysis. The modified intent-to-treat and safety populations comprised 1,410 patients and 1,447 patients, respectively. Titration period : Compared with placebo (32/21%), significantly smaller proportions of patients taking ESL 800 mg (20/15%) and 1,200 mg (22/12%) had a ≥25/≥50% increase in standardized seizure frequency (SSF) from baseline; there was no significant difference between placebo and ESL 400 mg. Maintenance period : Compared with placebo (20%), significantly smaller proportions of patients taking ESL (400 mg, 12%; 800 mg, 12%; 1,200 mg, 14%) had an increase in SSF ≥25%. When evaluating ≥50% increases in SSF, only ESL 800 mg (7%) was significantly different from placebo (12%). Some patients had no secondarily generalized tonic-clonic (sGTC) seizures during baseline but had ≥1 sGTC seizure during maintenance treatment (placebo, 11%; ESL 400 mg, 5%; 800 mg, 10%; 1,200 mg, 5%). Fewer patients had a ≥25% increase in sGTC seizure frequency with ESL (400 mg, 11%; 800 mg, 9%; 1,200 mg, 14%) versus placebo (19%). The incidence of seizures reported as TEAEs was low in all treatment groups; incidences were generally lower with ESL versus placebo. Tapering-off period : Similar proportions of patients taking ESL and placebo had a ≥25/≥50% increase in SSF. Seizure TEAE incidence was numerically higher with ESL versus placebo. Treatment with adjunctive ESL does not appear to

    The objective of this study is to evaluate the effects of cytochrome P450 2C19 (CYP2C19) polymorphism on adverse cardiovascular events (MACE) in Hakka patients with acute coronary syndrome (ACS) receiving clopidogrel who had undergone coronary drug-eluting stent placement after percutaneous coronary intervention (PCI) in southern China. Genotyping of CYP2C19 and MACE of 934 ACS patients with PCI on clopidogrel maintenance therapy were analyzed. Patients who carried loss-of-function CYP2C19 were treated with a 150-mg maintenance dose of clopidogrel or 90 mg of ticagrelor antiplatelet therapy, and patients who were non-carriers received clopidogrel therapy daily at a maintenance dose of 75 mg and the patients were followed-up for at least 12 months. The primary efficacy endpoint was a composite of cardiovascular death, myocardial infarction, and target vessel revascularization and stroke. The allelic frequency of CYP2C19*2 and CYP2C19*3 of Hakka patients in the current study was 31.64 and 5.19%, respectively. The CYP2C19 wild-type homozygotes (*1/*1) were the most predominant among the patients (40.36%), followed by the CYP2C19*2 heterozygotes (*1/*2) (40.26%). The distribution of CYP2C19 phenotypes was divided into extensive metabolizers (EM; 40.36%), intermediate metabolizers (IM; 45.61%), and poor metabolizers (PM; 14.03%). Based on the genotype-guided antiplatelet therapy, there was no significant association between the carrier status and the clinical outcome at 1, 6, and 12 months. In addition, no significant difference in the rates of bleeding was found among the three groups. After logistic regression analysis, hypertension was the only independent predictor of cardiovascular events (relative risk, 1.501; 95% CI, 1.011 to 2.229; P = 0.044). Our results shed new light on the important benefit of testing CYP2C19 polymorphisms before prescribing clopidogrel in patients treated with drug-eluting stent implantation after PCI. The testing may help to

To start with, we performed some exploratory studies aimed at learning some preliminary lessons on this type of analysis: Assessment of the interest of probabilistic incident analysis; possibility of using PSA scenarios; skills and resources required. At the same time, EPN created a working group whose assignment was to define a new approach for analysis of incidents on NPPs. This working group gave thought to both aspects of Operating Feedback that EPN wished to improve: Analysis of significant incidents; analysis of potential consequences. We took part in the work of this group, and for the second aspects, we proposed a method based on an adaptation of the event-tree method in order to establish a link between existing PSA models and actual incidents. Since PSA provides an exhaustive database of accident scenarios applicable to the two most common types of units in France, they are obviously of interest for this sort of analysis. With this method we performed some incident analyses, and at the same time explores some methods employed abroad, particularly ASP (Accident Sequence Precursor, a method used by the NRC). Early in 1994 EDF began a systematic analysis programme. The first, transient phase will set up methods and an organizational structure. 7 figs

    It is unclear whether a healthy lifestyle mitigates the adverse effects of job strain on coronary artery disease. We examined the associations of job strain and lifestyle risk factors with the risk of coronary artery disease. We pooled individual-level data from 7 cohort studies comprising 102 128 men and women who were free of existing coronary artery disease at baseline (1985-2000). Questionnaires were used to measure job strain (yes v. no) and 4 lifestyle risk factors: current smoking, physical inactivity, heavy drinking and obesity. We grouped participants into 3 lifestyle categories: healthy (no lifestyle risk factors), moderately unhealthy (1 risk factor) and unhealthy (2-4 risk factors). The primary outcome was incident coronary artery disease (defined as first nonfatal myocardial infarction or cardiac-related death). There were 1086 incident events in 743,948 person-years at risk during a mean follow-up of 7.3 years. The risk of coronary artery disease among people who had an unhealthy lifestyle compared with those who had a healthy lifestyle (hazard ratio [HR] 2.55, 95% confidence interval [CI] 2.18-2.98; population attributable risk 26.4%) was higher than the risk among participants who had job strain compared with those who had no job strain (HR 1.25, 95% CI 1.06-1.47; population attributable risk 3.8%). The 10-year incidence of coronary artery disease among participants with job strain and a healthy lifestyle (14.7 per 1000) was 53% lower than the incidence among those with job strain and an unhealthy lifestyle (31.2 per 1000). The risk of coronary artery disease was highest among participants who reported job strain and an unhealthy lifestyle; those with job strain and a healthy lifestyle had half the rate of disease. A healthy lifestyle may substantially reduce disease risk among people with job strain.

    Full Text Available Abstract Background Aspirin has been recommended for the prevention of major adverse cardiovascular events (MACE, composite of non-fatal myocardial infarction, non-fatal stroke, and cardiovascular death in diabetic patients without previous cardiovascular disease. However, recent meta-analyses have prompted re-evaluation of this practice. The study objective was to evaluate the relative and absolute benefits and harms of aspirin for the prevention of incident MACE in patients with diabetes. Methods We performed a systematic review and meta-analysis on seven studies (N = 11,618 reporting on the use of aspirin for the primary prevention of MACE in patients with diabetes. Two reviewers conducted a systematic search of electronic databases (MEDLINE, EMBASE, the Cochrane Library, and BIOSIS and hand searched bibliographies and clinical trial registries. Reviewers extracted data in duplicate, evaluated the quality of the trials, and calculated pooled estimates. Results A total of 11,618 participants were included in the analysis. The overall risk ratio (RR for MACE was 0.91 (95% confidence intervals, CI, 0.82-1.00 with little heterogeneity among trials (I2 0.0%. Secondary outcomes of interest included myocardial infarction (RR, 0.85; 95% CI, 0.66-1.10, stroke (RR, 0.84; 95% CI, 0.64-1.11, cardiovascular death (RR, 0.95; 95% CI, 0.71-1.27, and all-cause mortality (RR, 0.95; 95% CI, 0.85-1.06. There were higher rates of hemorrhagic and gastrointestinal events. In absolute terms, these relative risks indicate that for every 10,000 diabetic patients treated with aspirin, 109 MACE may be prevented at the expense of 19 major bleeding events (with the caveat that the relative risk for the latter is not statistically significant. Conclusions The studies reviewed suggest that aspirin reduces the risk of MACE in patients with diabetes without cardiovascular disease, while also causing a trend toward higher rates of bleeding and gastrointestinal complications

    The aim of this study was to assess the prognostic value of 64-slice CT angiography (CTA) in patients with known or suspected coronary artery disease (CAD). Sixty-four-slice coronary CTA was performed in 220 patients [mean age 63 {+-} 11 years, 77 (35%) female] with known or suspected CAD. CTA images were analyzed with regard to the presence and number of coronary lesions. Patients were followed-up for the occurrence of the following clinical endpoints: death, nonfatal myocardial infarction, unstable angina, and coronary revascularization. During a mean follow-up of 14 {+-} 4 months, 59 patients (27%) reached at least one of the predefined clinical endpoints. Patients with abnormal coronary arteries on CTA (i.e., presence of coronary plaques) had a 1st-year event rate of 34%, whereas in patients with normal coronary arteries no events occurred (event rate, 0%, p < 0.001). Similarly, obstructive lesions ({>=}50% luminal narrowing) on CTA were associated with a high first-year event rate (59%) compared to patients without stenoses (3%, p < 0.001). The presence of obstructive lesions was a significant independent predictor of an adverse cardiac outcome. Sixty-four-slice CTA predicts cardiac events in patients with known or suspected CAD. Conversely, patients with normal coronary arteries on CTA have an excellent mid-term prognosis. (orig.)

    Full Text Available OBJETIVO: Verificar o efeito da denervação cardíaca ventral na incidência de fibrilação atrial no pós-operatório de revascularização cirúrgica do miocárdio. MÉTODOS: Entre setembro e novembro de 2005, 50 pacientes consecutivos da mesma instituição foram alocados neste estudo prospectivo e randomizado. Foram selecionados pacientes portadores de insuficiência coronariana com indicação de revascularização cirúrgica do miocárdio, sem história ou diagnóstico prévio de arritmia atrial. Os critérios de exclusão foram: idade acima de 75 anos, história prévia de arritmia atrial e operações cardíacas associadas. A denervação era realizada antes do início da circulação extracorpórea pela remoção do tecido gorduroso ao redor da veia cava superior, aorta e artéria pulmonar. Os grupos foram comparados de acordo com as características clínicas, demográficas e variáveis operatórias. RESULTADOS: Não houve mortalidade hospitalar em ambos os grupos. O tempo médio adicional para realização da denervação foi de 7,64 + 2,33 minutos e não houve complicações associadas ao procedimento. Cinco pacientes apresentaram fibrilação atrial no pós-operatório, sendo dois (8% no grupo controle e três (12% no grupo denervação.

    The TRA·CER trial compared vorapaxar, a novel platelet protease-activated receptor (PAR)-1 antagonist, with placebo in 12 944 patients with high-risk non-ST-segment elevation acute coronary syndromes (NSTE ACS). In this analysis, we explored the effect of vorapaxar on myocardial infarction (MI). A blinded, independent central endpoint adjudication committee prospectively defined and classified MI according to the universal MI definition, including peak cardiac marker value (creatine kinase-MB [CK-MB] and/or troponin). Because the trial failed to meet its primary endpoint, these analyses are considered exploratory. During a median follow-up of 502 days, 1580 MIs occurred in 1319 patients. The majority (n = 1025, 64.9%) were type 1 (spontaneous) MI, followed by type 4a [percutaneous coronary intervention (PCI)-related] MI (n = 352; 22.3%). Compared with placebo, vorapaxar reduced the hazard of a first MI of any type by 12% [hazard ratio (HR), 0.88; 95% confidence interval (CI), 0.79-0.98; P = 0.021] and the hazard of total number of MIs (first and subsequent) by 14% (HR, 0.86; 95% CI, 0.77-0.97; P = 0.014), an effect that was sustained over time. Vorapaxar reduced type 1 MI by 17% (HR, 0.83; 95% CI, 0.73-0.95; P = 0.007). Type 4a MIs were not significantly reduced by vorapaxar (HR, 0.90; 95% CI, 0.73-1.12; P = 0.35). Vorapaxar effect was consistent across MI sizes defined by peak cardiac marker elevations and across key clinical subgroups; however, in patients not treated with thienopyridine at baseline (HR, 0.65; 95% CI, 0.46-0.92) compared with patients who received thienopyridine (HR, 0.91; 95% CI, 0.81-1.02), there was a trend towards a higher effect (Pint = 0.077). The PAR-1 antagonist vorapaxar was associated with a reduction of MI, including total number of infarctions. This reduction was sustained over time and was mostly evident in type 1 MI, the most common type of MI observed.

    In this 8 years' follow-up study, we evaluated the long-term outcomes of the addition of clopidogrel to aspirin during the first year after coronary artery bypass grafting, versus aspirin plus placebo, with respect to survival, major adverse cardiac, or major cerebrovascular events, including revascularization, functional status, graft patency, and native coronary artery disease progression. In the initial Clopidogrel After Surgery for Coronary Artery Disease trial, 113 patients were randomized to receive either daily clopidogrel (n = 56) or placebo (n = 57), in addition to aspirin, in a double-blind fashion for 1 year after coronary artery bypass grafting. All patients were re-evaluated to collect long-term clinical data. Surviving patients with a glomerular filtration rate > 30 mL/min were asked to undergo a coronary computed tomography angiogram to evaluate the late saphenous vein graft patency and native coronary artery disease progression. At a median follow-up of 7.6 years, survival rate was 85.5% ± 3.8% (P = .23 between the 2 groups). A trend toward enhanced freedom from all-cause death or major adverse cardiac or cerebrovascular events, including revascularization, was observed in the aspirin-clopidogrel group (P = .11). No difference in functional status or freedom from angina was observed between the 2 groups (P > .57). The long-term patency of saphenous vein graft was 89.11% in the aspirin-clopidogrel group versus 91.23% in the aspirin-placebo group (P = .79). A lower incidence of moderate to severe native disease progression was observed in the aspirin-clopidogrel group versus the aspirin-placebo group (7 out of 122 vs 13 out of 78 coronary segments that showed progression, respectively [odds ratio, 0.3 ± 0.2; 95% confidence interval, 0.1-0.8; P = .02]). At 8 years' follow-up, the addition of clopidogrel to aspirin during the first year after coronary artery bypass grafting exhibited a lower incidence of moderate to severe

    We sought to determine the impact of proximal cap ambiguity on procedural techniques and outcomes for coronary chronic total occlusion (CTO) percutaneous coronary intervention (PCI). We examined the clinical and angiographic characteristics and outcomes of 1021 CTO-PCIs performed between 2012 and 2015 at 11 United States centers. Proximal cap ambiguity was present in 31% of target lesions and was associated with increased clinical and angiographic complexity (prior coronary artery bypass graft surgery: 43% vs 33%; P=.01; moderate/severe calcification 66% vs 51%; Pambiguity (68% vs 33%; Pambiguity was associated with increased use of intravascular ultrasound (49% vs 36%; P=.01) and contrast (281 mL vs 250 mL; Pambiguity is present in one-third of CTO-PCI target lesions and is associated with lower success rates, higher utilization of the retrograde approach, and lower procedural efficiency, but no significant difference in the incidence of major adverse cardiac events.

    It is unknown how risk of myocardial infarction and stroke differ for patients with and without anxiety or depression, and whether this risk can be explained by demographics, medication use, cardiovascular risk factors. The aim of this study is to quantify differences in risk of non-fatal MI or stroke among patients with anxiety or depression. Prospective cohort study examining risk of incident MI and stroke between March 2005 and March 2015 for 524,952 patients aged 30 and over from the east London primary care database for patients with anxiety or depression. Amongst 21,811 individuals with depression at baseline, 1.2% had MI and 0.4% had stroke. Of 22,128 individuals with anxiety at baseline, 1.1% had MI and 0.3% had stroke. Depression was independently associated with both MI and stroke, whereas anxiety was associated with MI only before adjustment for cardiovascular risk factors. Antidepressant use increased risk for MI but not stroke. Mean age at first MI was lower in those with anxiety, while mean age at first stroke was lower in those with depression. The study was limited to patients currently registered in the database and thus we did not have any patients that died during the course of follow-up. Patients with depression have increased risk of cardiovascular events. The finding of no increased cardiovascular risk in those with anxiety after adjusting for cardiovascular risk factors is of clinical importance and highlights that the adequate control of traditional risk factors is the cornerstone of cardiovascular disease prevention. Targeting management of classical cardiovascular risk factors and evaluating the risks of antidepressant prescribing should be prioritized. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available Introduction. Psychological reactions are often comorbid with coronary risk factors and could be important for a six-month outcome. Objective. Determination of anxiety level, depression and aggression, persistence of risk health behaviour, stress life events, and coronary risk factors after coronary event and a predictive value of those parameters for six-month rehospitalization. Methods. In the group with Angina Pectoris (E1=30 and the group with Acute Myocardial Infarction (E2=33, there were applied, at baseline and after 6 months, the following: Semistructured Clinical Interview based on ICD-10, for depressive episode and anxiety disorder, Hamilton Anxiety Scale (HAMA, Hamilton Depression Scale (HAMD, KON-6 sigma Scale for aggression, Holms-Rahe Scale (H-R for stress events and Questionnaire for risk behaviour: alcohol consumption, smoking, lack of physical activity. Group differences were assessed by t-test and chi-square test, p<0.05, regression analysis for assessing initial variables, a predictive value for six month rehospitalization. Results. After acute coronary event, the anxiety and depression levels were mild and aggression was low in E1 and mild in E2. Stress event score was significantly higher in E2 (H-R=115.18 than in E1 (H-R=72.20, p<0.05. After 6 months, the results were the same except for a significantly lower stress event score in E1 (H-R=49.48, and in E2 (H-R=91.65, but still significantly higher than in E1. Coronary parameters were reduced, smokers' rate was increased in E1. Alcohol consumption, hypercholesterolaemia and hereditary tendency were predictive for six- month rehospitalization. Conclusion. After acute cardiac event, hospitalized coronary patients had a mild anxiety, depression and aggression level as well as after six months. The infarct patients had experienced more stress life events in the previous year than the angina patients. Risk health behaviour did not change in the following six months, with the

    The presence of heavy coronary artery calcification increases the complexity of percutaneous coronary intervention (PCI) and increases the incidence of major adverse cardiac events (MACE): death, myocardial infarction (MI), target vessel revascularization (TVR), and stent thrombosis. The ORBIT II (Evaluate the Safety and Efficacy of OAS in Treating Severely Calcified Coronary Lesions) trial reported low rates of procedural, 30-day, 1-year, and 2-year ischemic complications after treatment of de novo, severely calcified lesions with the Diamondback 360° Coronary Orbital Atherectomy System (OAS) (Cardiovascular Systems, Inc.). ORBIT II was a single-arm trial that enrolled 443 patients at 49U.S. sites; in this study, de novo, severely calcified coronary lesions were treated with OAS prior to stenting. The primary safety endpoint was 30-day MACE: the composite of cardiac death, MI, and TVR (inclusive of target lesion revascularization (TLR)). The primary efficacy endpoint was procedural success: stent delivery with a residual stenosis of atherectomy. There were 360 (81.3%) subjects who completed the protocol-mandated 3-year visit.The overall cumulative rate of 3-year MACE was 23.5%, including cardiac death (6.7%), MI (11.2%), and TVR (10.2%). The 3-year target lesion revascularization rate was 7.8%. In the final 3-year analysis of the ORBIT II trial, orbital atherectomy of severely calcified coronary lesions followed by stenting resulted in a low rate of adverse ischemic events compared with historical controls.Orbital atherectomy represents a safe and effective revascularization strategy for patients with severely calcified coronary lesions. The ORBIT II trial enrolled 443 subjects to study orbital atherectomy followed by stenting for de novo severely calcified coronary lesions. The overall cumulative 3-year MACE rate was 23.5%, including cardiac death (6.7%), MI (11.2%), and TVR (10.2%); the 3-year target lesion revascularization rate was 7.8%. Orbital atherectomy

    Williams syndrome is a contiguous gene deletion syndrome resulting from a heterozygous deletion on chromosome 7q11.23, and is characterized by distinctive facial features and supravalvular aortic stenosis (SVAS). This syndrome rarely presents unpredictable cardiac death, and yet, as illustrated in the present case, it is still not possible to predict it, even on close monitoring. We herein describe the case of a 6-year-old Japanese girl with Williams syndrome, who had sudden cardiac collapse due to cardiac infarction after pharyngitis. Cardiac failure followed a critical course that did not respond to catecholamine support or heart rest with extracardiac mechanical support. Although marked coronary stenosis was not present, the left coronary cusp abnormally adhered to the aortic wall, which may synergistically cause coronary ostium occlusion with SVAS. Altered hemodynamic state, even that caused by the common cold, may lead to critical myocardial events in Williams syndrome with SVAS. © 2015 Japan Pediatric Society.

    Full Text Available Acute pulmonary edema is a serious event. Its occurrence in association with interrupted aortic arch and coronary heart disease is rare. Recently, an old patient developed cardiogenic shock and acute pulmonary edema due to acute coronary insufficiency, associated with interrupted aortic arch. The coronary angiography revealed occlusion of the right coronary artery and 95% obstruction in the left main coronary artery, associated with interruption of the descending aorta. Coronary artery bypass graft was performed, without extracorporeal circulation, to the anterior descending coronary artery. We discuss the initial management, given the seriousness of the case.

    Full Text Available Abstract Aim To prospectively determine the role of platelet glycoprotein IIIa (GP IIIa gene PlA1/PlA2 polymorphism on the long-term clinical outcome in patients with coronary artery disease undergoing coronary stenting. Design and setting Prospective observational study in the University Hospital of Caen (France. Patients and methods 1 111 symptomatic consecutive Caucasian patients treated with percutaneous coronary intervention including stent implantation underwent genotyping for GP IIIa PlA1/A2. Main outcome measures Long-term clinical outcome in terms of the rate of major adverse cardiac events (MACE, ie death from any cause, non-fatal Q wave or non Q wave myocardial infarction, and need for coronary revascularisation was obtained and subsequently stratified according to the GP IIIa PlA1/A2 polymorphism. Results Three groups of patients were determined according to the GP IIIa PlA1/A2 polymorphism (71.6% had the A1/A1, 25.8% had the A1/A2 and 2.6% had the A2/A2 genotype. These three groups were comparable for all clinical characteristics including sex ratio, mean age, vascular risk factors, previous coronary events, baseline angiographic exam, indication for the percutaneous coronary intervention and drug therapy. The incidence of MACE was similar in these 3 groups of patients during a mean follow-up period of 654+/-152 days. Independent risk factors for MACE were a left ventricular ejection fraction Conclusion The GP IIIa PlA1/A2 polymorphism does not influence the clinical long-term outcome in patients with symptomatic coronary disease undergoing percutaneous coronary intervention with stent implantation.

    The chest pain can be use for stratifying the risk of the patients after coronary angioplasty. Nevertheless this strategy has shown to have a low accuracy in the detection of restenosis and myocardial ischemia. Aims: To establish the usefulness of the SPECT studies in the risk stratification after the coronary angioplasty. Evaluate the incidence of silent ischemia or symptomatic, and its impact on the prognosis. Method: There were included 107 patients (p) submitted to a gated SPECT between the year of the coronary angioplasty. The analysis of the images was performed according to different scores (SSS, SRS, SDS). These data was correlated with the symptoms of the patients. We define group 1 (G1) as the asymptomatic without ischemia (n 59p), group 2 (G2) as silent ischemia (n = 28p) and group 3 (G3) as symptomatic with ischemia (n = 20p). A clinical follow-up was done in search of events (target vessel revascularization, unstable angina, AMI and death). Results: Significant differences were not observed in the clinical variables between the different groups. The SSS was lower in the G1 compare with G2 and G3 (p 0.0001) and was similar between the last two, p = NS (SSS: G1: 2.2 ± 4.9; G2: 7.6 ± 5.9; G3: 9.5 ± 6.8). The SDS was greater in G3 vs. G1 and G2, p = 0.0001, and greater in G2 vs. G1, p = 0.0001 (SDS: G1: 0; G2: 4.8 ± 3.5; G3: 7.2 ± 6.5). No differences where observed in the SRS between the three groups. In the follow-up the total percentage of events was lesser when compare the G1 with the G2 and G3 (G1: 3.3%; G2 and G3: 18.7%; p 0.02). The percentage of annual events of the G3 symptomatic with ischemia (11.03%) and G2 silent ischemia (4.04%) did not present differences (p 0.7). When the events of the G2 (4.04%) were compared with the G1 (1.24%) we observed a trend to major frequency of events in the G2 (p = 0.6). Conclusions: The presence of myocardial ischemia after coronary angioplasty is a determinant of the prognosis. Nevertheless, the extension

    Elevated neutrophil-to-lymphocyte ratio (NLR) and mean platelet volume (MPV) are indirect inflammatory markers. There is some evidence that both are associated with worse outcomes in ST-segment elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (PCI). The aim of the present study was to compare the capacity of NLR and MPV to predict adverse events after primary PCI. In a prospective cohort study, 625 consecutive patients with STEMI, who underwent primary PCI, were followed. Receiver operating characteristic (ROC) curve analysis was performed to calculate the area under the curve (AUC) for the occurrence of procedural complications, mortality and major adverse cardiovascular events (MACE). Mean age was 60.7 (±12.1) years, 67.5% were male. The median of NLR was 6.17 (3.8-9.4) and MPV was 10.7 (10.0-11.3). In multivariate analysis, both NLR and MPV remained independent predictors of no-reflow (relative risk [RR] = 2.26; 95%confidence interval [95%CI] = 1.16-4.32; p = 0.01 and RR = 2.68; 95%CI = 1.40-5.10; p  0.05). NLR had an excellent negative predictive value (NPV) of 96.7 for no-reflow and 89.0 for in-hospital MACE. Despite no difference in the ROC curve comparison with MPV, only NLR remained an independent predictor for in-hospital MACE. A low NLR has an excellent NPV for no-reflow and in-hospital MACE, and this could be of clinical relevance in the management of low-risk patients. Copyright © 2018 Elsevier B.V. All rights reserved.

    We sought to estimate the incidence and predictors of all-cause mortality 6 months after heart failure hospitalization in Uganda. Mbarara Heart Failure Registry is a cohort of patients hospitalized with a clinical diagnosis of heart failure at Mbarara Regional Referral Hospital, Uganda. We measured serum electrolytes, cardiac markers, and echocardiograms. All participants were followed until death or end of 6 months. We used Fine and Gray models to estimate the incidence and predictors all-cause mortality. A total of 215 participants were enrolled, 141 (66%) were women, and mean age 53 (standard deviation 22) years. Nineteen (9%) had diabetes, 40 (19%) had HIV, and 119 (55%) had hypertension. The overall incidence of all-cause mortality was 3.58 (95% CI 2.92, 4.38) per 1000 person-days. Men had higher incidence of death compared to women (4.02 vs 3.37 per 1000 person-days). The incidence of all-cause mortality during hospitalization was almost twice that of in the community (27.5 vs 14.77 per 1000 person-days). In adjusted analysis, increasing age, NYHA class IV, decreasing renal function, smoking, each unit increase in serum levels of Potassium, BNP, and Creatine kinase-MB predicted increased incidence of 6 months all-cause death whereas taking beta-blockers and having an index admission on a weekend compared to a week day predicted survival. There is a high incidence of all-cause mortality occurring in-hospital among patients hospitalized with heart failure in rural Uganda. Heart failure directed therapies should be instituted to curb heart failure-related mortality. Copyright © 2017 Elsevier B.V. All rights reserved.

    Multidetector computed tomography (MDCT) has started its implementation in cardiology with calcium quantification of coronary plaques in the study without contrast, using the calcium score, demonstrating an important independent predictor of future cardiac events. The examination with intravenous contrast, coronary angiography, appeared later as a noninvasive method for evaluation of anatomy and obstructive coronary disease, characterizing the degree of stenosis and the presence of non calcified atherosclerotic plaques, assessing not only the lumen, but also the vessel wall. With the advent of new machines with more detectors and higher temporal resolution has been a reduction in radiation dose and the possibility of new applications. (author)

    The usefulness of percutaneous transluminal coronary angioplasty (PTCA) was assessed in patients with exercise-induced asymptomatic myocardial ischemia (silent ischemia) and compared with exercise-induced symptomatic myocardial ischemia (symptomatic ischemia). Patients with single vessel coronary artery disease (51 with angina pectoris, 40 with old myocardial infarction) and evidence of stress-induced ischemia on thallium-201 single photon emission computed tomography (SPECT) underwent successful PTCA. Thirty-seven percent of angina patients and 60% of infarction patients showed asymptomatic exercise-induced ischemia. There was no significant difference in population characteristics between silent and symptomatic patients. Patients with silent angina had significantly higher percentage thallium uptake and washout rate than symptomatic patients. After PTCA, both percentage diameter stenosis and percentage thallium uptake were improved in all patients with angina irrespective of the presence or absence of symptoms. There were no significant differences in percentage thallium uptake and washout rate between patients with silent and symptomatic infarction. After PTCA, percentage diameter stenosis, percentage thallium uptake, and washout rate improved in all infarction patients irrespective of the symptoms. Zero percent of silent angina patients, 12% of symptomatic angina patients, 12% of silent infarction patients, 19% of symptomatic infarction patients had cardiac events during about 4.5 years after PTCA. The incidence of cardiac events did not significantly differ in any patient group. PTCA improved myocardial perfusion in all patients, and the incidence of cardiac events did not differ between the silent and symptomatic groups. Revascularization with PTCA is suitable for patients with silent as well as symptomatic ischemia. (author)

    Full Text Available Abstract Background Coronary artery disease remains the dominant cause of mortality in developed countries. While platelets have been recognized to play a pivotal role in atherothrombosis, the ideal antiplatelet regime after coronary artery surgery remains elusive. The evolution of CABG has presently moved beyond technical improvements to involve modulation of pharmacologic management designed to improve patient outcomes. The aim of this trial will be to test the hypothesis that the addition of clopidogrel to patients with documented postoperative aspirin resistance will reduce the incidence of major cardiovascular events. Methods Patients scheduled for isolated coronary artery surgery will be eligible for the study. Patients in whom postoperative multiple electrode aggregometry documents aspirin resistance will be randomized into two groups. The control group will receive 300 mg of aspirin. The dual antiplatelet group will receive 75 mg of clopidogrel in addition to 300 mg of aspirin. Patients will be followed for 6 months. Major adverse cardiac and cerebrovascular events (death from any cause, myocardial infarction, stroke, hospitalization due to cardiovascular pathology as well as bleeding events will be recorded. Discussion This will be the first trial that will specifically address the issue of dual antiplatelet therapy in patients undergoing coronary artery surgery who have been found to be aspirin resistant. In the event that the addition of clopidogrel proves to be beneficial in this subset of surgical patients, this study could significantly impact their future antiplatelet management. This randomized controlled trial has been registered at the ClinicalTrials.gov website (Identifier NCT01159639.

    Coronary computed tomography angiography (CCTA) is a new approach for the diagnosis of anatomical coronary artery disease (CAD), but it is unclear how CCTA performs compared with the standard approach of functional stress testing. To compare the clinical effectiveness of CCTA with that of functional stress testing for patients with suspected CAD. A systematic literature search was conducted in PubMed and MEDLINE for English-language randomized clinical trials of CCTA published from January 1, 2000, to July 10, 2016. Researchers selected randomized clinical trials that compared a primary strategy of CCTA with that of functional stress testing for patients with suspected CAD and reported data on patient clinical events and changes in therapy. Two reviewers independently extracted data from and assessed the quality of the trials. This analysis followed the PRISMA statement for reporting systematic reviews and meta-analyses and used the Cochrane Collaboration's tool for assessing risk of bias in randomized trials. The Mantel-Haenszel method was used to conduct the primary analysis. Summary relative risks were calculated with a random-effects model. The outcomes of interest were all-cause mortality, cardiac hospitalization, myocardial infarction, invasive coronary angiography, coronary revascularization, new CAD diagnoses, and change in prescription for aspirin and statins. Thirteen trials were included, with 10 315 patients in the CCTA arm and 9777 patients in the functional stress testing arm who were followed up for a mean duration of 18 months. There were no statistically significant differences between CCTA and functional stress testing in death (1.0% vs 1.1%; risk ratio [RR], 0.93; 95% CI, 0.71-1.21) or cardiac hospitalization (2.7% vs 2.7%; RR, 0.98; 95% CI, 0.79-1.21), but CCTA was associated with a reduction in the incidence of myocardial infarction (0.7% vs 1.1%; RR, 0.71; 95% CI, 0.53-0.96). Patients undergoing CCTA were significantly more likely to undergo

    Full Text Available OBJECTIVE: To assess the in-hospital results and clinical follow-up of young patients (< 50 years with multivessel coronary artery disease undergoing stent implantation in native coronary arteries and to compare their results with those of patients with single-vessel coronary artery disease. METHODS: We retrospectively studied 462 patients undergoing coronary stent implantation. Patients were divided into 2 groups: group I (G-I - 388 (84% patients with single-vessel coronary artery disease; and group II (G-II - 74 (16% patients with multivessel coronary artery disease. RESULTS: The mean age of the patients was 45±4.9 years, and the clinical findings at presentation and demographic data were similar in both groups. The rate of clinical success was 95% in G-I and 95.8% in G-II (P=0.96, with no difference in regard to in-hospital evolution between the groups. Death, acute myocardial infarction, and the need for myocardial revascularization during clinical follow-up occurred in 10.1% and 11.2% (P=0.92 in G-I and G-II, respectively. By the end of 24 months, the actuarial analysis showed an event-free survival of 84.6 % in G-I and 81.1% in G-II (P=0.57. CONCLUSION: Percutaneous treatment with coronary stent implantation in young patients with multivessel disease may be safe with a high rate of clinical success, a low incidence of in-hospital complications, and a favorable evolution in clinical follow-up.

    Systematic reviews examining associations of depressive disorder with coronary heart disease and stroke produce mixed results. Failure to consider reverse causation and dose-response patterns may have caused inconsistencies in evidence. This prospective cohort study on depressive disorder, coronary heart disease, and stroke analysed reverse causation and dose-response effects using four 5-year and three 10-year observation cycles (total follow up 24 years) based on multiple repeat measures of exposure. Participants in the Whitehall II study (n = 10,036, 31,395 person-observations, age at start 44.4 years) provided up to six repeat measures of depressive symptoms via the 30-item General Health Questionnaire (GHQ-30) and one measure via Center for Epidemiologic Studies Depression Scale (CES-D). The cohort was followed up for major coronary events (coronary death/nonfatal myocardial infarction) and stroke (stroke death/morbidity) through the national mortality register Hospital Episode Statistics, ECG-screening, medical records, and self-report questionnaires. GHQ-30 caseness predicted stroke over 0-5 years (age-, sex- and ethnicity-adjusted HR 1.60, 95% CI 1.1-2.3) but not over 5-10 years (HR 0.94, 95% CI 0.6-1.4). Using the last 5-year observation cycle, cumulative GHQ-30 caseness was associated with incident coronary heart disease in a dose-response manner (1-2 times a case: HR 1.12, 95% CI 0.7-1.7; 3-4 times: HR 2.06, 95% CI 1.2-3.7), and CES-D caseness predicted coronary heart disease (HR 1.81, 95% CI 1.1-3.1). There was evidence of a dose-response effect of depressive symptoms on risk of coronary heart disease. In contrast, prospective associations of depressive symptoms with stroke appeared to arise wholly or partly through reverse causation.

    The prognostic importance of age among well-known prognostic factors such as extent of coronary artery lesions, cardiac function, and myocardial ischemia was evaluated in 147 elderly patients with coronary artery disease aged 65 years or older who underwent dipyridamole perfusion scintigraphy and coronary angiography. After excluding 32 patients who initially underwent percutaneous transluminal coronary angioplasty (PTCA) or coronary artery bypass grafting (CABG), 115 patients who were initially treated medically were analysed by the Cox model for cardiac events during a mean follow-up period of 29±22 months. Among the 114 patients who were available for follow-up, nine patients (7.9%) had cardiac events, including five cardiac deaths and four non-fatal cardiac events (requiring PTCA or CABG). When the 114 patients were divided into three age-groups; 53 patients aged 65-69 years, 42 aged 70-74 years and 19 aged 75 years or older, the incidence of cardiac death was highest in those aged 75 years or older. Univariate analysis showed that age of 70 years or older (hazards ratio 15.15, p=0.004), scintigraphic diffuse slow washout (hazards ratio 8.77, p=0.002), and triple-vessel or left main trunk disease (hazards ratio 6.36, p=0.05) were important prognostic factors. Multivariate analysis showed that scintigraphic diffuse slow washout (hazards ratio 6.33, p=0.05), and triple-vessel or left main trunk disease (hazards ratio 11.94 p=0.05) were statistically significant as independent prognostic factors. However, when age of 70 years or older was included in the analysis, it showed higher hazards ratio (21.21, p=0.03) than that of scintigraphic diffuse slow washout (7.36) or triple-vessel or left main trunk disease (5.30). Age of 70 years or older may be a significant prognostic factor in elderly patients with coronary artery disease which has an equivalent importance to the extent of coronary lesions. (author)

    The risk of incidents involving mass decontamination in response to a chemical, biological, radiological, or nuclear release has increased in recent years, due to technological advances, and the willingness of terrorists to use unconventional weapons. Planning for such incidents has focused on the technical issues involved, rather than on psychosocial concerns. This paper presents a novel experimental study, examining the effect of three different responder communication strategies on public experiences and behaviour during a mass decontamination field experiment. Specifically, the research examined the impact of social identity processes on the relationship between effective responder communication, and relevant outcome variables (e.g. public compliance, public anxiety, and co-operative public behaviour). All participants (n = 111) were asked to visualise that they had been involved in an incident involving mass decontamination, before undergoing the decontamination process, and receiving one of three different communication strategies: 1) ‘Theory-based communication’: Health-focused explanations about decontamination, and sufficient practical information; 2) ‘Standard practice communication’: No health-focused explanations about decontamination, sufficient practical information; 3) ‘Brief communication’: No health-focused explanations about decontamination, insufficient practical information. Four types of data were collected: timings of the decontamination process; observational data; and quantitative and qualitative self-report data. The communication strategy which resulted in the most efficient progression of participants through the decontamination process, as well as the fewest observations of non-compliance and confusion, was that which included both health-focused explanations about decontamination and sufficient practical information. Further, this strategy resulted in increased perceptions of responder legitimacy and increased

    Full Text Available The risk of incidents involving mass decontamination in response to a chemical, biological, radiological, or nuclear release has increased in recent years, due to technological advances, and the willingness of terrorists to use unconventional weapons. Planning for such incidents has focused on the technical issues involved, rather than on psychosocial concerns. This paper presents a novel experimental study, examining the effect of three different responder communication strategies on public experiences and behaviour during a mass decontamination field experiment. Specifically, the research examined the impact of social identity processes on the relationship between effective responder communication, and relevant outcome variables (e.g. public compliance, public anxiety, and co-operative public behaviour. All participants (n = 111 were asked to visualise that they had been involved in an incident involving mass decontamination, before undergoing the decontamination process, and receiving one of three different communication strategies: 1 'Theory-based communication': Health-focused explanations about decontamination, and sufficient practical information; 2 'Standard practice communication': No health-focused explanations about decontamination, sufficient practical information; 3 'Brief communication': No health-focused explanations about decontamination, insufficient practical information. Four types of data were collected: timings of the decontamination process; observational data; and quantitative and qualitative self-report data. The communication strategy which resulted in the most efficient progression of participants through the decontamination process, as well as the fewest observations of non-compliance and confusion, was that which included both health-focused explanations about decontamination and sufficient practical information. Further, this strategy resulted in increased perceptions of responder legitimacy and increased

    Full Text Available The enzyme in matrix metalloproteinase (MMP-9 has been suggested to be an important determinant of plaque degradation. While several studies have shown elevated levels in patients with coronary heart disease, results in prospective population based studies evaluating MMP-9 in relation to first time coronary events have been inconclusive. As of today, there are four published studies which have measured MMP-9 in serum and none using plasma. Measures of MMP-9 in serum have been suggested to have more flaws than measures in plasma.To investigate the independent association between plasma levels of MMP-9 and first-time incidence of coronary events in an 8-year follow-up.428 men and 438 women, aged 45-69 years, free of previous coronary events and stroke at baseline, were followed-up. Adjustments were made for sex, age, socioeconomic position, behavioral and cardiovascular risk factors, chronic disease at baseline, depressive symptoms, interleukin-6 and C-reactive protein.53 events were identified during a risk-time of 6 607 person years. Hazard ratio (HR for MMP-9 after adjustment for all covariates were HR = 1.44 (1.03 to 2.02, p = 0.033. Overall, the effect of adjustments for other cardiovascular risk factors was low.Levels of plasma MMP-9 are independently associated with risk of first-time CHD events, regardless of adjustments. These results are in contrast to previous prospective population-based studies based on MMP-9 in serum. It is essential that more studies look at MMP-9 levels in plasma to further evaluate the association with first coronary events.

    Full text: Introduction: Circumflex (Cx) coronary artery congenital anomaly is reported to be less than 1% incidence. Coronary arteries with aberrant origin are more likely to have atherosclerosis according to some published literatures. Objectives and tasks: In this study we aim to present computed tomography (CT) angiography findings of a patient, who has Cx artery with aberrant origin and atherosclerotic. Materials and methods: 57-year-old woman without any symptoms who has risk factors to atherosclerosis was referred to our clinic for coronary CT angiography. Results: In CT angiography; we detected Cx coronary artery with aberrant origin (right sinus of valsalva) and retroaortic course. Also we saw intimal irregularities and calcified plaque causing severe narrowing in the proximal segment of artery. Right coronary and left anterior descendant arteries had mild atherosclerosis. Conclusion: Coroner CT angiography, which allows multiplanar imaging with high resolution, is an effective diagnostic tool for coronary artery disease, like not only congenital anomalies but also acquired atherosclerotic disease

This study aimed to assess the effect of reaching an LDL-C goal of <70 mg/dL (<1.8 mmol/L on first composite cardiovascular outcomes in routine clinical practice in Thailand.Methods: A retrospective cohort study was conducted using medical charts and the electronic hospital database of patients diagnosed with ACS and treated with statins at a tertiary care hospital in Thailand between 2009 and 2012. After admission, patients were followed from the date of LDL-C goal assessment until the first event of composite cardiovascular outcomes (nonfatal ACS, nonfatal stroke, or all-cause death. Cox proportional hazard models adjusted for potential confounders were used.Results: Of 405 patients, mean age was 65 years (60% males. Twenty-seven percent of the patients attained an LDL-C goal of <70 mg/dL, 38% had LDL-C between 70 and 99 mg/dL, and 35% had LDL-C ≥100 mg/dL. Forty-six patients experienced a composite

    Full Text Available We here report a case of ST-elevation myocardial infarction (STEMI due to simultaneous acute coronary artery occlusions of two major coronary arteries in a patient with coronary ectasia. The patient had been previously submitted to percutaneous coronary angioplasty with bare metal stent implantation in both culprit vessels. Very late stent thrombosis could be the cause of the first occlusion, triggering the event in the other vessel. In addition, concomitant embolic sources were not identified. Although routine aspiration thrombectomy in STEMI was not proven to be beneficial in randomized clinical trials, it was of great value in this case. We also discuss the relation between coronary ectasia, chronic inflammatory status, and increased platelet activity which may have caused plaque disruption in another already vulnerable vessel.

    This study aimed to examine predictors and clinical outcomes of periprocedural myocardial infarction (PMI) after chronic total occlusion (CTO) intervention. There are limited data on the clinical implications of PMI after CTO intervention in the new-generation drug-eluting stent (DES) era. We enrolled 337 patients who underwent CTO intervention and met the study criteria. We evaluated the incidence and predictors of PMI, defined as an increase in creatine kinase-MB ≥3× the upper limit of normal (ULN) after intervention and compared the occurrence rates of major adverse cardiac and cerebrovascular events (MACCE, defined as the composite of cardiac death, myocardial infarction, stent thrombosis, target-vessel revascularization, or cerebrovascular accidents) between the PMI and non-PMI groups. PMI occurred in 23 (6.8%) patients after CTO intervention. Significant independent predictors were previous bypass surgery [odds ratio (OR) = 5.52, 95% confidence interval (CI) = 1.17-25.92; P = 0.03], Japan-CTO score ≥3 (OR = 7.06, 95%CI = 2.57-19.39; P PMI group had a significantly higher MACCE rate than the non-PMI group (23.7 vs. 5.6%, P = 0.008 by log-rank test). PMI was an independent predictor of MACCE (HR = 4.26, 95%CI = 1.35-13.43; P = 0.01). The MACCE rate gradually increased in a CK-MB-dependent fashion and was highest in patients with ≥10× ULN (P = 0.005). Previous bypass surgery, high Japan-CTO score, side branch occlusion, and longer procedure time were strongly related to PMI occurrence after CTO intervention. PMI was significantly associated with worse clinical outcomes in the new-generation DES era. © 2017 Wiley Periodicals, Inc.

    Recent studies have suggested ABO blood type locus as an inherited predictor of thrombosis, cardiovascular risk factors, myocardial infarction. However, data is scarce about the impact of non-O blood groups on prognosis in patients with ST-elevation myocardial infarction (STEMI). Therefore, we aimed to evaluate the prognostic importance of non-O blood groups in patients with STEMI undergoing primary percutaneous coronary intervention (pPCI) METHODS: 1835 consecutive patients who were admitted with acute STEMI between 2010 and 2015 were included and followed-up for a median of 35.6months. The prevalence of hyperlipidemia, total cholesterol, LDL, peak CKMB and no-reflow as well as hospitalization duration were higher in patients with non-O blood groups. Gensini score did not differ between groups. During the in-hospital and long-term follow-up period, MACE, the prevalence of stent thrombosis, non-fatal MI, and mortality were higher in non-O blood groups. In multivariate logistic regression analysis, non-0 blood groups were demonstrated to be independent predictors of in-hospital (OR:2.085 %CI: 1.328-3.274 p=0.001) and long term MACE (OR:2.257 %CI: 1.325-3.759 pblood group compared with O blood group (pblood groups were determined to be significant prognostic indicators of short- and long-term cardiovascular adverse events and mortality in patients with STEMI undergoing pPCI. In conjunction with other prognostic factors, evaluation of this parameter may improve the risk categorization and tailoring the individual therapy and follow-up in STEMI patient population.

    Among patients receiving clopidogrel for coronary artery disease, concomitant therapy with proton pump inhibitors (PPIs) has been associated with an increased risk for recurrent coronary events. Factores de Riesgo y ENfermedad Arterial (FRENA) is an ongoing, multicenter, observational registry of consecutive outpatients with coronary artery disease, cerebrovascular disease, or peripheral artery disease. We retrospectively examined the influence of concomitant use of PPIs on outcome in patients receiving clopidogrel. As of March 2009, 1222 patients were using clopidogrel: 595 had coronary artery disease, 329 cerebrovascular disease, and 298 had peripheral artery disease. Of these, 519 (42%) were concomitantly using PPIs. Over a mean follow-up of 15 months, 131 patients (11%) had 139 subsequent ischemic events: myocardial infarction 44, ischemic stroke 40, and critical limb ischemia 55. Seventeen of them (13%) died within 15 days of the subsequent event. PPI users had a higher incidence of myocardial infarction (rate ratio, 2.5; 95% confidence interval [CI], 1.3-4.8), ischemic stroke (rate ratio, 1.9; 95% CI, 1.03-3.7), and a nonsignificantly higher rate of critical limb ischemia (rate ratio, 1.6; 95% CI, 0.95-2.8) than nonusers. On multivariate analysis, concomitant use of clopidogrel and PPIs was independently associated with an increased risk for subsequent ischemic events both in the whole series of patients (hazard ratio, 1.8; 95% CI, 1.1-2.7) and in those with cerebrovascular disease or peripheral artery disease (hazard ratio, 1.5; 95% CI, 1.01-2.4). In patients with established arterial disease, concomitant use of PPIs and clopidogrel was associated with a nearly doubling of the incidence of subsequent myocardial infarction or ischemic stroke. This higher incidence persisted after multivariate adjustment.

    Objective: To explore the influence of thrombus aspiration combined with intra-coronary administration of the glycoprotein Ⅱ b/Ⅲ a inhibitor, Tirofiban, on myocardial microcirculation when percutaneous coronary intervention (PCI) is employed for the treatment of acute ST-segment elevation myocardial infarction. Methods: During the period from April 2008 to June 2010, percutaneous coronary interventional was performed in 184 consecutive patients with acute ST-segment elevation myocardial infarction. The patients were randomly divided into study group (n=78) and control group (n=106). Thrombus aspiration combined with intra-coronary administration of Tirofiban was used in patients of study group, while routine PCI together with intravenous administration of Tirofiban was adopted in patients of control group. Clinical features, TIMI grade, myocardial blush grade, ratio of ST falling >70% at 24 hours after treatment, incidence of massive haemorrhage, hospitalization, days, major adverse cardiac event within 30 days were observed, and the results were compared between two groups. Results: The incidence of no reflow phenomenon in study group was markedly lower than that in control group (5.67% vs. 21.14%, P=0.011), while the myocardial blush grade was much higher in study group than that in control group (2.03±0.32 vs. 1.12±0.47, P=0.021). The ratio of ST falling > 70% at 24 hours after treatment in study group was increased (94% vs. 85%, P=0.003), and the occurrence of perioperative massive haemorrhage was lower (9% vs. 4%, P=0.03). The incidence of major adverse cardiac event within 30 days was distinctly decreased although it was quite similar in both groups (5.5% vs. 6.1%, P=0.786). Conclusion: Thrombus aspiration combined with intra-coronary administration of Tirofiban is superior to conventional PCI in effectively improving the reperfusion of myocardial microcirculation and in reliably reducing perioperative risk.

    Although aortic stiffness assessed by pulse wave velocity (PWV) is a strong predictor of coronary artery disease, the significance of local coronary stiffness has never been tackled. The first objective of this study was to describe a method of measuring coronary PWV (CoPWV) invasively and to describe its determinants. The second objective was to assess both CoPWV and aortic PWV in patients presenting with acute coronary syndromes or stable coronary artery disease. In 53 patients, CoPWV was measured from the delay in pressure wave and distance traveled as a pressure wire was withdrawn from the distal to the proximal coronary segment. Similarly, aortic PWV was measured invasively when the wire was pulled across the ascending aorta; carotid-femoral PWV was also measured noninvasively using the SphygmoCor system (AtCor Medical). Mean CoPWV was 10.3±6.1 m/s. Determinants of increased CoPWV were fractional flow reserve, diastolic blood pressure, and previous stent implantation in the recorded artery. CoPWV was lower in patients with acute coronary syndromes versus stable coronary artery disease (7.6±3 versus 11.5±6.4 m/s; P=0.02), and this persisted after adjustment for confounders. In contrast, aortic stiffness, assessed by aortic and carotid-femoral PWV, did not differ significantly. CoPWV seems associated with acute coronary events more closely than aortic PWV. High coronary compliance, whether per se or because it leads to a distal shift in compliance mismatch, may expose vulnerable plaques to high cyclic stretch. CoPWV is a new tool to assess local compliance at the coronary level; it paves the way for a new field of research. © 2017 The Authors.

    Full Text Available Background: The impact of sequential vein bypass grafting on clinical outcomes is less known in off-pump coronary artery bypass grafting (CABG. We aimed to evaluate the effects of sequential vein bypass grafting on clinical outcomes in off-pump CABG. Methods: From October 2009 to September 2013 at the Fuwai Hospital, 127 patients with at least one sequential venous graft were matched with 127 patients of individual venous grafts only, using propensity score matching method to obtain risk-adjusted outcome comparison. In-hospital measurement was composite outcome of in-hospital death, myocardial infarction (MI, stroke, requirement for intra-aortic ballon pump (IABP assistance and prolonged ventilation. Major adverse cardiac events (MACEs: Death, MI or repeat revascularization and angina recurrence were considered as mid-term endpoints. Results: No significant difference was observed among the groups in baseline characteristics. Intraoperative mean blood flow per vein graft was 40.4 ml in individual venous grafts groups versus 59.5 ml in sequential venous grafts groups (P < 0.001. There were no differences between individual and sequential venous grafts groups with regard to composite outcome of in-hospital mortality, MI, stroke, IABP assistance and prolonged ventilation (11.0% vs. 14.2%, P = 0.45. Individual in-hospital measurement also did not differ significantly between the two groups. At about four years follow-up, the survival estimates free from MACEs (92.5% vs. 97.3%, P = 0.36 and survival rates free of angina recurrence (80.9% vs. 85.5%, P = 0.48 were similar among individual and sequential venous grafts groups with a mean follow-up of 22.5 months. In the Cox regression analysis, sequential vein bypass grafting was not identified as an independent predictor of both MACEs and angina recurrence. Conclusions: Compared to individual vein bypass grafting, sequential vein bypass grafting was not associated with an increase of either in

    An increase in the number of CT investigations will likely result in a an increase in unrequested information. Clinical relevance of these findings is unknown. This is the first follow-up study to investigate the prognostic relevance of subclinical coronary (CAC) and aortic calcification (TAC) as contained in routine diagnostic chest CT in a clinical care population. The follow-up of 10,410 subjects (>40 years) from a multicentre, clinical care-based cohort of patients included 240 fatal to 275 non-fatal cardiovascular disease (CVD) events (mean follow-up 17.8 months). Patients with a history of CVD were excluded. Coronary (0-12) and aortic calcification (0-8) were semi-quantitatively scored. We used Cox proportional-hazard models to compute hazard ratios to predict CVD events. CAC and TAC were significantly and independently predictive of CVD events. Compared with subjects with no calcium, the adjusted risk of a CVD event was 3.7 times higher (95% CI, 2.7-5.2) among patients with severe coronary calcification (CAC score ≥6) and 2.7 times higher (95% CI, 2.0-3.7) among patients with severe aortic calcification (TAC score ≥5). Subclinical vascular calcification on CT is a strong predictor of incident CVD events in a routine clinical care population. (orig.)
