Abstract: The authors sought to define which guideline-advocated therapies are associated with the greatest benefit with respect to 6-month survival in patients hospitalised with an acute coronary syndrome (ACS). The authors conducted a nested case-control study of ACS patients within the Global Registry of Acute Coronary Events cohort between April 1999 and December 2007. The cases were ACS patients who survived to discharge but died within 6 months. The controls were patients who survived to 6 months, matched for ACS diagnosis, age and the Global Registry of Acute Coronary Events risk score. Rates of use of evidence-based medications and coronary interventions (angiography, percutaneous coronary intervention and coronary artery bypass graft surgery) were compared. Logistic regression including matched variables was used, and the attributable mortality from incomplete application of each therapy was calculated. A total of 1716 cases and 3432 controls were identified. Coronary artery bypass graft surgery and percutaneous coronary intervention were associated with the greatest 6-month survival benefit (OR for death 0.60 (95% CI 0.39 to 0.90) and 0.57 (0.48 to 0.72), respectively). Statins and clopidogrel provided the greatest independent pharmacologic benefit (ORs for death 0.85 (0.73 to 0.99) and 0.84 (0.72 to 0.99)) with lesser effects seen with other pharmacotherapies. A diminishing benefit associated with each additional ACS therapy is evident. These data may provide a rational basis for selecting between therapeutic options when compliance or cost is an issue.

Abstract: Marked changes in the prevalence of noncommunicable diseases such as obesity, diabetes, and cardiovascular disease have occurred in developed and developing countries in recent decades. The overarching aim of the study is to examine the relationship of societal influences on human lifestyle behaviors, cardiovascular risk factors, and incidence of chronic noncommunicable diseases. The Prospective Urban Rural Epidemiology (PURE) study is a large-scale epidemiological study that plans to recruit approximately 140,000 in iduals residing in >600 communities in 17 low-, middle-, and high-income countries around the world. In idual data collection includes medical history, lifestyle behaviors (physical activity and dietary profile), blood collection and storage for biochemistry and future genetic analysis, electrocardiogram, and anthropometric measures. In addition, detailed information is being collected with respect to 4 environmental domains of interest-the built environment, nutrition and associated food policy, psychosocial/socioeconomic factors, and tobacco environment. A minimum follow-up of 10 years is currently planned. This report describes the design, justification, and methodology of the PURE study. The PURE study has been recruiting since 2002 and has enrolled 139,506 in iduals by March 31, 2009. The PURE study builds on the work and experience gained through conduct of the INTERHEART study. Its design and extensive data collection are geared toward addressing major questions on causation and development of the underlying determinants of cardiovascular disease in populations at varying stages of epidemiologic transition.

Abstract: To analyse whether the benefits and risks of rivaroxaban plus aspirin vary in patients with comorbidities and receiving multiple drugs. In patients with coronary or peripheral artery disease, adding low-dose rivaroxaban to aspirin reduces cardiovascular events and mortality. Polypharmacy and multimorbidity are frequent in such patients. We describe ischaemic events (cardiovascular death, stroke, or myocardial infarction) and major bleeding in participants from the randomized, double-blind COMPASS study by number of cardiovascular medications and concomitant medical conditions. We compared event rates and hazard ratios (HRs) for rivaroxaban plus aspirin vs. aspirin alone by the number of medications and concomitant conditions, and tested for interaction between polypharmacy or multimorbidity and the antithrombotic regimen. The risk of ischaemic events was higher in patients with more concomitant drugs (HR 1.7, 95% confidence interval 1.5–2.1 for & vs. 0–2) and with more comorbidities (HR 2.3, 1.8–2.1 for & vs. 0–1). Multimorbidity, but not polypharmacy, was associated with a higher risk of major bleeding. The relative efficacy, safety, and net clinical benefit of rivaroxaban were not affected by the number of drugs or comorbidities. Patients taking more concomitant medications derived the largest absolute reduction in the net clinical outcome with added rivaroxaban (1.1% vs. 0.4% reduction with & vs. 0–2 cardiovascular drugs, number needed to treat 91 vs. 250). Adding low-dose rivaroxaban to aspirin resulted in benefits irrespective of the number of concomitant drugs or comorbidities. Multiple comorbidities and/or polypharmacy should not dissuade the addition of rivaroxaban to aspirin in otherwise eligible patients.

Abstract: We evaluated lipoprotein‐associated phospholipase A 2 (Lp‐ PLA 2 ) activity in patients with stable coronary heart disease before and during treatment with darapladib, a selective Lp‐ PLA 2 inhibitor, in relation to outcomes and the effects of darapladib in the STABILITY trial. Plasma Lp‐ PLA 2 activity was determined at baseline (n=14 500) at 1 month (n=13 709) serially (n=100) at 3, 6, and 18 months and at the end of treatment. Adjusted Cox regression models evaluated associations between Lp‐ PLA 2 activity levels and outcomes. At baseline, the median Lp‐ PLA 2 level was 172.4 μmol/min per liter (interquartile range 143.1–204.2 μmol/min per liter). Comparing the highest and lowest Lp‐ PLA 2 quartile groups, the hazard ratios were 1.50 (95% CI 1.23–1.82) for the primary composite end point (cardiovascular death, myocardial infarction, or stroke), 1.95 (95% CI 1.29–2.93) for hospitalization for heart failure, 1.42 (1.07–1.89) for cardiovascular death, and 1.37 (1.03–1.81) for myocardial infarction after adjustment for baseline characteristics, standard laboratory variables, and other prognostic biomarkers. Treatment with darapladib led to a ≈65% persistent reduction in median Lp‐ PLA 2 activity. There were no associations between on‐treatment Lp‐ PLA 2 activity or changes of Lp‐ PLA 2 activity and outcomes, and there were no significant interactions between baseline and on‐treatment Lp‐ PLA 2 activity or changes in Lp‐ PLA 2 activity levels and the effects of darapladib on outcomes. Although high Lp‐ PLA 2 activity was associated with increased risk of cardiovascular events, pharmacological lowering of Lp‐ PLA 2 activity by ≈65% did not significantly reduce cardiovascular events in patients with stable coronary heart disease, regardless of the baseline level or the magnitude of change of Lp‐ PLA 2 activity.

Abstract: The COMPASS (Cardiovascular Outcomes for People Using Anticoagulation Strategies) trial showed that the combination of low-dose rivaroxaban and aspirin reduced major vascular events in patients with stable vascular disease. The purpose of this study was to identify subsets of patients at higher risk of recurrent vascular events, which may help focus the use of rivaroxaban and aspirin therapy. COMPASS patients with vascular disease were risk stratified using 2 methods: the REACH (REduction of Atherothrombosis for Continued Health) atherothrombosis risk score and CART (Classification and Regression Tree) analysis. The absolute risk differences for rivaroxaban with aspirin were compared to aspirin alone over 30 months for the composite of cardiovascular death, myocardial infarction, stroke, acute limb ischemia, or vascular utation for severe bleeding and for the net clinical benefit. High-risk patients using the REACH score were those with 2 or more vascular beds affected, history of heart failure (HF), or renal insufficiency, and by CART analysis were those with ≥2 vascular beds affected, history of HF, or diabetes. Rivaroxaban and aspirin combination reduced the serious vascular event incidence by 25% (4.48% vs. 5.95%, hazard ratio: 0.75 95% confidence interval: 0.66 to 0.85), equivalent to 23 events prevented per 1,000 patients treated for 30 months, at the cost of a nonsignificant 34% increase in severe bleeding (1.34 95% confidence interval: 0.95 to 1.88), or 2 events caused per 1,000 patients treated. Among patients with ≥1 high-risk feature identified from the CART analysis, rivaroxaban and aspirin prevented 33 serious vascular events, whereas in lower-risk patients, rivaroxaban and aspirin treatment led to the avoidance of 10 events per 1,000 patients treated for 30 months. In patients with vascular disease, further risk stratification can identify higher-risk patients (≥2 vascular beds affected, HF, renal insufficiency, or diabetes). The net clinical benefit remains favorable for most patients treated with rivaroxaban and aspirin compared with aspirin.

Abstract: To determine the effect of education and other measures of socioeconomic status (SES) on risk of acute myocardial infarction (AMI) in patients and controls from countries with erse economic circumstances (high, middle, and low income countries). Case-control study. 52 countries from all inhabited regions of the world. 12242 cases and 14622 controls. First non-fatal AMI. SES was measured using education, family income, possessions in the household and occupation. Low levels of education (< or =8 years) were more common in cases compared to controls (45.0% and 38.1% p<0.0001). The odds ratio (OR) for low education adjusted for age, sex and region was 1.56 (95% confidence interval 1.47 to 1.66). After further adjustment for psychosocial, lifestyle, other factors and mutually for other socioeconomic factors, the OR associated with education < or =8 years was 1.31 (1.20 to 1.44) (p<0.0001). Modifiable lifestyle factors (smoking, exercise, consumption of vegetables and fruits, alcohol and abdominal obesity) explained about half of the socioeconomic gradient. Family income, numbers of possessions and non-professional occupation were only weakly or not at all independently related to AMI. In high-income countries (World Bank Classification), the risk factor adjusted OR associated with low education was 1.61 (1.33 to 1.94), whereas it was substantially lower in low-income and middle-income countries: 1.25 (1.14 to 1.37) (p for interaction 0.045). Of the SES measures we studied, low education was the marker most consistently associated with increased risk for AMI globally, most markedly in high-income countries.

Abstract: Rosuvastatin (10 mg per day) compared with placebo reduced major adverse cardiovascular (CV) events by 24% in 12 705 participants at intermediate CV risk after 5.6 years. There was no benefit of blood pressure (BP) lowering treatment in the overall group, but a reduction in events in the third of participants with elevated systolic BP. After cessation of all the trial medications, we examined whether the benefits observed during the active treatment phase were sustained, enhanced, or attenuated. After the randomized treatment period (5.6 years), participants were invited to participate in 3.1 further years of observation (total 8.7 years). The first co-primary outcome for the entire length of follow-up was the composite of myocardial infarction, stroke, or CV death [major adverse cardiovascular event (MACE)-1], and the second was MACE-1 plus resuscitated cardiac arrest, heart failure, or coronary revascularization (MACE-2). In total, 9326 (78%) of 11 994 surviving Heart Outcomes Prevention Evaluation (HOPE)-3 subjects consented to participate in extended follow-up. During 3.1 years of post-trial observation (total follow-up of 8.7 years), participants originally randomized to rosuvastatin compared with placebo had a 20% additional reduction in MACE-1 [95% confidence interval (CI), 0.64–0.99] and a 17% additional reduction in MACE-2 (95% CI 0.68–1.01). Therefore, over the 8.7 years of follow-up, there was a 21% reduction in MACE-1 (95% CI 0.69–0.90, P = 0.005) and 21% reduction in MACE-2 (95% CI 0.69–0.89, P = 0.002). There was no benefit of BP lowering in the overall study either during the active or post-trial observation period, however, a 24% reduction in MACE-1 was observed over 8.7 years. The CV benefits of rosuvastatin, and BP lowering in those with elevated systolic BP, compared with placebo continue to accrue for at least 3 years after cessation of randomized treatment in in iduals without cardiovascular disease indicating a legacy effect.

Abstract: Antiplatelets and anticoagulants are associated with increased upper gastrointestinal bleeding. We evaluated whether proton pump inhibitor therapy could reduce this risk. We performed a 3 × 2 partial factorial double-blind trial of 17,598 participants with stable cardiovascular disease and peripheral artery disease. Participants were randomly assigned to groups given pantoprazole 40 mg daily or placebo, as well as rivaroxaban 2.5 mg twice daily with aspirin 100 mg once daily, rivaroxaban 5 mg twice daily, or aspirin 100 mg alone. The primary outcome was time to first upper gastrointestinal event, defined as a composite of overt bleeding, upper gastrointestinal bleeding from a gastroduodenal lesion or of unknown origin, occult bleeding, symptomatic gastroduodenal ulcer or ≥5 erosions, upper gastrointestinal obstruction, or perforation. There was no significant difference in upper gastrointestinal events between the pantoprazole group (102 of 8791 events) and the placebo group (116 of 8807 events) (hazard ratio, 0.88 95% confidence interval [CI], 0.67-1.15). Pantoprazole significantly reduced bleeding of gastroduodenal lesions (hazard ratio, 0.52 95% confidence interval, 0.28-0.94 P = .03) this reduction was greater when we used a post-hoc definition of bleeding gastroduodenal lesion (hazard ratio, 0.45 95% confidence interval, 0.27-0.74), although the number needed to treat still was high (n = 982 95% confidence interval, 609-2528). In a randomized placebo-controlled trial, we found that routine use of proton pump inhibitors in patients receiving low-dose anticoagulation and/or aspirin for stable cardiovascular disease does not reduce upper gastrointestinal events, but may reduce bleeding from gastroduodenal lesions.

Abstract: Cholesterol and blood pressure (BP) can be effectively and safely lowered with statin drugs and BP-lowering drugs, reducing major cardiovascular (CV) events by 20%-30% within 5 years in high-risk in iduals. However, there are limited data in lower-risk populations. The Heart Outcomes Prevention Evaluation-3 (HOPE-3) trial is evaluating whether cholesterol lowering with a statin drug, BP lowering with low doses of 2 antihypertensive agents, and their combination safely reduce major CV events in in iduals at intermediate risk who have had no previous vascular events and have average cholesterol and BP levels. A total of 12,705 women 65 years or older and men 55 years or older with at least 1 CV risk factor, no known CV disease, and without any clear indication or contraindication to the study drugs were randomized to rosuvastatin 10 mg/d or placebo and to candesartan/hydrochlorothiazide 16/12.5 mg/d or placebo (2 × 2 factorial design) and will be followed for a mean of 5.8 years. The coprimary study outcomes are the composite of CV death, nonfatal myocardial infarction (MI), and nonfatal stroke and the composite of CV death, nonfatal MI, nonfatal stroke, resuscitated cardiac arrest, heart failure, and arterial revascularization. Participants were recruited from 21 countries in North America, South America, Europe, Asia, and Australia. Mean age at randomization was 66 years and 46% were women. The HOPE-3 trial will provide new information on cholesterol and BP lowering in intermediate-risk populations with average cholesterol and BP levels and is expected to inform approaches to primary prevention worldwide (HOPE-3 ClinicalTrials.gov NCT00468923).

Abstract: Covert vascular disease of the brain manifests as infarcts, white matter hyperintensities, and microbleeds on MRI. Their cumulative effect is often a decline in cognition, motor impairment, and psychiatric disorders. Preventive therapies for covert brain ischemia have not been established but represent a huge unmet clinical need. The MRI substudy examines the effects of the antithrombotic regimens in COMPASS on incident covert brain infarcts (the primary outcome), white matter hyperintensities, and cognitive and functional status in a s le of consenting COMPASS participants without contraindications to MRI. COMPASS is a randomized superiority trial testing rivaroxaban 2.5 mg bid plus acetylsalicylic acid 100 mg and rivaroxaban 5 mg bid against acetylsalicylic acid 100 mg per day for the combined endpoint of MI, stroke, and cardiovascular death in in iduals with stable coronary artery disease or peripheral artery disease. T1-weighted, T2-weighted, T2*-weighted, and FLAIR images were obtained close to randomization and near the termination of assigned antithrombotic therapy biomarker and genetic s les at randomization and one month, and cognitive and functional assessment at randomization, after two years and at the end of study. Between March 2013 and May 2016, 1905 participants were recruited from 86 centers in 16 countries. Of these participants, 1760 underwent baseline MRI scans that were deemed technically adequate for interpretation. The mean age at entry of participants with interpretable MRI was 71 years and 23.5% were women. Coronary artery disease was present in 90.4% and 28.1% had peripheral artery disease. Brain infarcts were present in 34.8%, 29.3% had cerebral microbleeds, and 93.0% had white matter hyperintensities. The median Montreal Cognitive Assessment score was 26 (interquartile range 23–28). The COMPASS MRI substudy will examine the effect of the antithrombotic interventions on MRI-determined covert brain infarcts and cognition. Demonstration of a therapeutic effect of the antithrombotic regimens on brain infarcts would have implications for prevention of cognitive decline and provide insight into the pathogenesis of vascular cognitive decline.

Abstract: Stroke is a major global health problem. It is the third leading cause of death and the leading cause of adult disability. INTERHEART, a global case-control study of acute myocardial infarction in 52 countries (29,972 participants), identified nine modifiable risk factors that accounted for % of population-attributable risk. However, traditional risk factors (e.g. hypertension, cholesterol) appear to exert contrasting risks for stroke compared with coronary heart disease, and the etiology of stroke is far more heterogeneous. In addition, our knowledge of risk factors for stroke in low-income countries is inadequate, where a very large burden of stroke occurs. Accordingly, a similar epidemiological study is required for stroke, to inform effective population-based strategies to reduce the risk of stroke. i Methods: /i INTERSTROKE is an international, multicenter case-control study. Cases are patients with a first stroke within 72 h of hospital presentation in whom CT or MRI is performed. Proxy respondents are used for cases unable to communicate. Etiological and topographical stroke subtype is documented for all cases. Controls are hospital- and community-based, matched for gender, ethnicity and age (±5 years). A questionnaire (cases and controls) is used to acquire information on known and proposed risk factors for stroke. Cardiovascular (e.g. blood pressure) and anthropometric (e.g. waist-to-hip ratio) measurements are obtained at the time of interview. Nonfasting blood s les and random urine s les are obtained from cases and controls. i Study Significance: /i An effective global strategy to reduce the risk of stroke mandates systematic measurement of the contribution of the major vascular risk factors within defined ethnic groups and geographical locations.

Abstract: To assess whether long-term treatment with candesartan/hydrochlorothiazide, rosuvastatin, or their combination can slow cognitive decline in older people at intermediate cardiovascular risk. The Heart Outcomes Prevention Evaluation-3 (HOPE-3) study was a double-blind, randomized, placebo-controlled clinical trial using a 2 × 2 factorial design. Participants without known cardiovascular disease or need for treatment were randomized to candesartan (16 mg) plus hydrochlorothiazide (12.5 mg) or placebo and to rosuvastatin (10 mg) or placebo. Participants who were ≥70 years of age completed the Digit Symbol Substitution Test (DSST), the modified Montreal Cognitive Assessment, and the Trail Making Test Part B at baseline and study end. Cognitive assessments were completed by 2,361 participants from 228 centers in 21 countries. Compared with placebo, candesartan/hydrochlorothiazide reduced systolic blood pressure by 6.0 mm Hg, and rosuvastatin reduced low-density lipoprotein cholesterol by 24.8 mg/dL. Participants were followed up for 5.7 years (median), and 1,626 completed both baseline and study-end assessments. Mean participant age was 74 years (SD ±3.5 years) 59% were women 45% had hypertension and 24% had ≥12 years of education. The mean difference in change in DSST scores was −0.91 (95% confidence interval [CI] −2.25 to 0.42) for candesartan/hydrochlorothiazide compared with placebo, −0.54 (95% CI −1.88 to 0.80) for rosuvastatin compared with placebo, and −1.43 (95% CI −3.37 to 0.50) for combination therapy vs double placebo. No significant differences were found for other measures. Long-term blood pressure lowering with candesartan plus hydrochlorothiazide, rosuvastatin, or their combination did not significantly affect cognitive decline in older people. NCT00468923. This study provides Class II evidence that for older people, candesartan plus hydrochlorothiazide, rosuvastatin, or their combination does not significantly affect cognitive decline.

Abstract: OBJECTIVE—Impaired glucose tolerance (IGT) and/or impaired fasting glucose (IFG) are risk factors for diabetes, cardiovascular disease (CVD), and kidney disease. We determined the effects of ramipril and rosiglitazone on combined and in idual CVD and renal outcomes in people with IGT and/or IFG in the Diabetes REduction Assessment With ramipril and rosiglitazone Medication (DREAM) trial. RESEARCH DESIGN AND METHODS—A total of 5,269 people aged ≥30 years, with IGT and/or IFG without known CVD or renal insufficiency, were randomized to 15 mg/day ramipril versus placebo and 8 mg/day rosiglitazone versus placebo. A composite cardiorenal outcome and its CVD and renal components were assessed during the 3-year follow-up. RESULTS—Compared with placebo, neither ramipril (15.7% [412 of 2,623] vs. 16.0% [424 of 2,646] hazard ratio [HR] 0.98 [95% CI 0.84–1.13] P = 0.75) nor rosiglitazone (15.0% [394 of 2,635] vs. 16.8% [442 of 2,634] 0.87 [0.75–1.01] P = 0.07) reduced the risk of the cardiorenal composite outcome. Ramipril had no impact on the CVD and renal components. Rosiglitazone increased heart failure (0.53 vs. 0.08% HR 7.04 [95% CI 1.60–31.0] P = 0.01) but reduced the risk of the renal component (0.80 [0.68–0.93] P = 0.005) prevention of diabetes was independently associated with prevention of the renal component (P & 0.001). CONCLUSIONS—Ramipril did not alter the cardiorenal outcome or its components. Rosiglitazone, which reduced diabetes, also reduced the development of renal disease but not the cardiorenal outcome and increased the risk of heart failure.
