- AIMS: Age is one of the most powerful determinants of prognosis in myocardial infarction, but there is comparatively little recent data across the whole spectrum of acute coronary syndromes (ACS). We examined the impact of increasing age on clinical presentation and hospital outcome in a large sample of patients with ACS. METHODS AND RESULTS: Patients (n = 10 253) from the Euroheart ACS survey in 103 hospitals in 25 countries were investigated. There was a significant inverse association between the age and the likelihood of presenting with ST-elevation. For each decade of life, the odds of presenting with ST-elevation decreased by 0.82 [95% confidence interval (CI) 0.79-0.84]; P < 0.0001. Elderly patients were considerably less often treated by cardiologists, less extensively investigated, and, when presenting with ST-elevation ACS, less likely to be treated with reperfusion. Compared with patients <55 years, the odds ratios of hospital mortality were 1.87 (1.21-2.88) at age 55-64, 3.70 (2.51-5.44) at age 65-74, 6.23 (4.25-9.14) at age 75-84, and 14.5 (9.47-22.1) among patients > or =85 years, with no major differences across different types of admission or discharge diagnoses. CONCLUSION: Elderly ACS patients were less likely to present with ST-elevation but had substantial in-hospital mortality, yet they were markedly less intensively treated and investigated.

- Background Cardiac troponin T (cTnT) and I (cTnI) concentrations provide strong prognostic information in anticoagulated patients with atrial fibrillation (AF). Whether the associations between cardiac troponin concentrations and mortality and morbidity differ by sex is not known. Objectives To assess whether men and women have different concentrations and prognostic value of cTnT and cTnI measurements in anticoagulated patients with AF. Methods cTnT and cTnI concentrations were measured with high-sensitivity (hs) assays in EDTA plasma samples obtained from the multicentre ARISTOTLE trial, which randomized patients with AF and at least one risk factor for stroke or systemic embolic event to warfarin or apixaban. Patients were stratified according to sex and the associations between hs-troponin concentrations, and all-cause death, cardiac death, myocardial infarction, stroke or systemic embolic event and major bleeding were assessed in multivariable regression models. Results We found higher cardiac troponin concentrations in men (n = 9649) compared to women (n = 5331), both for hs-cTnT (median 11.8 [Q1-3 8.1-18.0] vs. 9.6 [6.7-14.3] ng L-1, P < 0.001) and hs-cTnI (5.8 [3.4-10.8] vs. 4.9 [3.1-8.8] ng L-1, P < 0.001). Adjusting for baseline demographics, comorbidities and medications, men still had significantly higher hs-troponin concentrations than women. C-reactive protein and N-terminal pro-B-type natriuretic peptide concentrations were higher in female patients. Both hs-cTnT and hs-cTnI concentrations were associated with all clinical outcomes similarly in men and women (p-value for interaction >0.05 for all end-points). Conclusion Men have higher hs-troponin concentrations than women in AF. Regardless of sex, hs-troponin concentrations remain similarly associated with adverse clinical outcomes in anticoagulated patients with AF.

- ObjectiveWe investigated the association between obesity and biomarkers indicating cardiac or renal dysfunction or inflammation and their interaction with obesity and outcomes.MethodsA total of 14 753 patients in the Apixaban for Reduction In STroke and Other ThromboemboLic Events in Atrial Fibrillation (ARISTOTLE) trial provided plasma samples at randomisation to apixaban or warfarin. Median follow-up was 1.9 years. Body Mass Index (BMI) was measured at baseline and categorised as normal, 18.5-25 kg/m(2); overweight, >25 to <30 kg/m(2); and obese, >= 30 kg/m(2). We analysed the biomarkers high-sensitivity C reactive protein (hs-CRP), interleukin 6 (IL-6), growth differentiation factor-15 (GDF-15), troponin T and N-terminal B-type natriuretic peptide (NT-pro-BNP). Outcomes included stroke/systemic embolism (SE), myocardial infarction (MI), composite (stroke/SE, MI, or all-cause mortality), all-cause and cardiac mortality, and major bleeding.ResultsCompared with normal BMI, obese patients had significantly higher levels of hs-CRP and IL-6 and lower levels of GDF-15, troponin T and NT-pro-BNP. In multivariable analyses, higher compared with normal BMI was associated with a lower risk of all-cause mortality (overweight: HR 0.73 (95% CI 0.63 to 0.86); obese: 0.67 (0.56 to 0.80), p<0.0001), cardiac death (overweight: HR 0.74 (95% CI 0.60 to 0.93); obese: 0.71 (0.56 to 0.92), p=0.01) and composite endpoint (overweight: 0.80 (0.70 to 0.92); obese: 0.72 (0.62 to 0.84), p<0.0001).ConclusionsRegardless of biomarkers indicating inflammation or cardiac or renal dysfunction, obesity was independently associated with an improved survival in anticoagulated patients with AF.

- AimsInflammation plays an important role in cardiovascular disease (CVD) development. The NOD-like receptor protein-3 (NLRP3) inflammasome contributes to the development of atherosclerosis in animal models. Components of the NLRP3 inflammasome pathway such as interleukin-1β can therapeutically be targeted. Associations of genetically determined inflammasome-mediated systemic inflammation with CVD and mortality in humans are unknown.Methods and resultsWe explored the association of genetic NLRP3 variants with prevalent CVD and cardiovascular mortality in 538 167 subjects on the individual participant level in an explorative gene-centric approach without performing multiple testing. Functional relevance of single-nucleotide polymorphisms on NLRP3 inflammasome activation has been evaluated in monocyte-enriched peripheral blood mononuclear cells (PBMCs). Genetic analyses identified the highly prevalent (minor allele frequency 39.9%) intronic NLRP3 variant rs10754555 to affect NLRP3 gene expression. rs10754555 carriers showed significantly higher C-reactive protein and serum amyloid A plasma levels. Carriers of the G allele showed higher NLRP3 inflammasome activation in isolated human PBMCs. In carriers of the rs10754555 variant, the prevalence of coronary artery disease was significantly higher as compared to non-carriers with a significant interaction between rs10754555 and age. Importantly, rs10754555 carriers had significantly higher risk for cardiovascular mortality during follow-up. Inflammasome inducers (e.g. urate, triglycerides, apolipoprotein C3) modulated the association between rs10754555 and mortality.ConclusionThe NLRP3 intronic variant rs10754555 is associated with increased systemic inflammation, inflammasome activation, prevalent coronary artery disease, and mortality. This study provides evidence for a substantial role of genetically driven systemic inflammation in CVD and highlights the NLRP3 inflammasome as a therapeutic target.

- Background: Although bradyarrhythmias have been observed with ticagrelor and its use with advanced atrioventricular block is not recommended, questions arise regarding its use in patients with mild conduction abnormalities. The objectives were to compare rates of clinically relevant arrhythmias in relation to any mild baseline conduction abnormality in patients with acute coronary syndrome randomized to ticagrelor versus clopidogrel. Methods: We included all subjects in the electrocardiographic (ECG) substudy of the Platelet Inhibition and Patient Outcomes trial, excluding those with missing baseline ECG or with a pacemaker at baseline (N = 15,460). Conduction abnormality was defined as sinus bradycardia, first-degree atrioventricular block, hemiblock, or bundle-branch block. The primary arrhythmic outcome was the composite of any symptomatic brady-or tachyarrhythmia, permanent pacemaker placement, or cardiac arrest through 12 months. Results: Patients with baseline conduction abnormalities (n = 4,256, 27.5%) were older and more likely to experience the primary arrhythmic outcome. There were no differences by ticagrelor versus clopidogrel in the composite arrhythmic end point in those with baseline conduction disease (1-year cumulative incidence rate: 17% for both study arms; hazard ratio: 0.99 [0.86-1.15]) or without baseline conduction disease (1-year cumulative incidence rate: clopidogrel 12.8% vs ticagrelor 12.4%; hazard ratio: 0.98 (0.88-1.09). There were also no statistically significant differences between ticagrelor and clopidogrel in the rates of bradycardic (or any individual arrhythmic) events in patients with baseline conduction abnormalities. Conclusions: Ticagrelor compared to clopidogrel did not increase arrhythmic events even in subjects with acute coronary syndrome who present with mild conduction abnormalities on their baseline ECG.

- Background Patients with a recent acute coronary syndrome (ACS) receiving oral antiplatelets and anticoagulants are at risk for bleeding and subsequent adverse non-bleeding-related events. Methods In this post hoc analysis, we evaluated 7,392 high-risk patients (median follow-up 241 days) with a recent ACS randomized to apixaban or placebo in APPRAISE-2. Clinical events during a 30-day period after Thrombolysis in Myocardial Infarction (TIMI) major/minor bleeding were analyzed using unadjusted and adjusted Cox proportional-hazards models. Results In total, 153 (2.1%) patients experienced TIMI major/minor bleeding during follow-up. Bleeding risk for patients on triple therapy (apixaban, thienopyridine, and aspirin) was increased compared with those on dual therapy (apixaban plus aspirin: hazard ratio [HR] 2.02, 95% CI 1.08-3.79; thienopyridine plus aspirin: HR 1.99, 95% CI 1.41-2.83). Those receiving apixaban/aspirin had similar bleeding risk compared with those receiving thienopyridine/aspirin (HR 1.01, 95% CI 0.53-1.95). Patients who experienced TIMI major/minor bleeding had an increased risk of 30-day all-cause mortality (HR 24.7, 95% CI 15.34-39.66) and ischemic events (HR 6.7, 95% CI 3.14-14.14). Conclusions In a contemporary cohort of high-risk patients after ACS, bleeding was associated with a significantly increased risk of subsequent ischemic events and mortality regardless of antithrombotic or anticoagulant strategy. Patients receiving apixaban plus aspirin had a similar bleeding risk compared with those receiving thienopyridine plus aspirin. Interventions to improve outcomes in patients after ACS should include strategies to optimize the reduction in ischemic events while minimizing the risk of bleeding.

- Background: Atrial fibrillation is associated with an increased risk of death. High-sensitivity troponin T, growth differentiation factor-15, NT-proBNP (N-terminal pro-B-type natriuretic peptide), and interleukin-6 levels are predictive of cardiovascular events and total cardiovascular death in anticoagulated patients with atrial fibrillation. The prognostic utility of these biomarkers for cause-specific death is unknown. Methods: The ARISTOTLE trial (Apixaban for the Prevention of Stroke in Subjects With Atrial Fibrillation) randomized 18201 patients with atrial fibrillation to apixaban or warfarin. Biomarkers were measured at randomization in 14798 patients (1.9 years median follow-up). Cox models were used to identify clinical variables and biomarkers independently associated with each specific cause of death. Results: In total, 1272 patients died: 652 (51%) cardiovascular, 32 (3%) bleeding, and 588 (46%) noncardiovascular/nonbleeding deaths. Among cardiovascular deaths, 255 (39%) were sudden cardiac deaths, 168 (26%) heart failure deaths, and 106 (16%) stroke/systemic embolism deaths. Biomarkers were the strongest predictors of cause-specific death: a doubling of troponin T was most strongly associated with sudden death (hazard ratio [HR], 1.48; P<0.001), NT-proBNP with heart failure death (HR, 1.62; P<0.001), and growth differentiation factor-15 with bleeding death (HR, 1.72; P=0.028). Prior stroke/systemic embolism (HR, 2.58; P>0.001) followed by troponin T (HR, 1.45; P<0.0029) were the most predictive for stroke/ systemic embolism death. Adding all biomarkers to clinical variables improved discrimination for each cause-specific death. Conclusions: Biomarkers were some of the strongest predictors of cause-specific death and may improve the ability to discriminate among patients' risks for different causes of death. These data suggest a potential role of biomarkers for the identification of patients at risk for different causes of death in patients anticoagulated for atrial fibrillation.

- BACKGROUND AND PURPOSE: Patients with prior stroke are at greater risk for recurrent cardiovascular events post-acute coronary syndromes (ACS) and may have a different risk/benefit profile with antithrombotic therapy than patients without prior stroke.METHODS: We studied 7391 patients with ACS from APPRAISE-2, stratified by the presence or absence of prior stroke. Baseline characteristics and outcomes of cardiovascular death, myocardial infarction (MI), or stroke were compared between groups. Interactions between prior stroke, treatment assignment (apixaban vs placebo), and outcomes were tested before and after multivariable adjustment with Cox proportional hazards models.RESULTS: A total of 902 patients (12%) had prior stroke. Those with prior stroke were older (69 vs 67 years), had more hypertension (91% vs 77%), peripheral vascular disease (22% vs18%), and impaired renal function (38% vs 30%) but less diabetes (44% vs 48%) than those without prior stroke. Patients with prior stroke vs no prior stroke had higher unadjusted rates of cardiovascular death (4.8% vs 4.0%), MI (11.2% vs 7.1%), and ischemic stroke (3.2% vs 0.9%). Patients with prior stroke assigned to apixaban had similar rates of the composite of cardiovascular death, MI, or stroke compared with those assigned to placebo (HR 1.39; 95% CI 0.92-2.08). Patients without prior stroke assigned to apixaban had similar rates of cardiovascular death, MI, or ischemic stroke compared with those assigned to placebo (HR 0.87; 95% CI 0.73-1.04; P-interaction=.041). Median follow-up was 240 days.CONCLUSIONS: Patients with prior stroke are at higher risk for recurrent cardiovascular events post-ACS and had a differential risk/benefit profile with oral anticoagulation.
