The aspirin controversy in primary prevention.

Purpose Of Review: Apparently conflicting meta-analysis results have led to renewed debate about the role of aspirin for the primary prevention of cardiovascular disease. We review the results of meta-analyses comparing aspirin with placebo or no aspirin for the primary prevention of cardiovascular disease and critically evaluate whether aspirin provides a net benefit.

Recent Findings: The results of four independently conducted meta-analyses between 2009 and 2012 involving between 95 000 and 102 621 individuals at low risk of cardiovascular disease are consistent with the results of the 2002 Antithrombotic Trialists' Collaboration meta-analysis, which found that aspirin reduces cardiovascular events primarily by reducing nonfatal myocardial infarction (MI).

Effect of colchicine compared with placebo on high sensitivity C-reactive protein in patients with acute coronary syndrome or acute stroke: a pilot randomized controlled trial.

There is a need for more effective therapies to reduce morbidity and mortality from cardiovascular disease. Inflammation plays a central role in the pathogenesis of atherosclerosis but no randomized studies have evaluated anti-inflammatory therapy in patients with acute coronary or cerebrovascular disease. We performed a pilot randomized controlled trial comparing the effect of colchicine 1 mg per day with placebo on high sensitivity C-reactive protein (CRP) levels and platelet function in 80 patients with acute coronary syndrome or acute ischemic stroke who were followed for 30 days.

Effect of aspirin on mortality in the primary prevention of cardiovascular disease.

Objective: The lack of a mortality benefit of aspirin in prior meta-analyses of primary prevention trials of cardiovascular disease has contributed to uncertainty about the balance of benefits and risks of aspirin in primary prevention. We performed an updated meta-analysis of randomized controlled trials of aspirin to obtain best estimates of the effect of aspirin on mortality in primary prevention.

Methods: Eligible articles were identified by searches of electronic databases and reference lists.

Preventing thrombophilia-related complications of pregnancy.

Pregnancy is associated with an increased risk of venous thromboembolism (VTE) and approximately half of all pregnancy-related VTEs are associated with thrombophilia. Recent studies suggest that there is a link between thrombophilia and other adverse pregnancy outcomes, such as fetal loss, preeclampsia, placental abruption and intrauterine growth restriction. However, the associations reported are modest, and high quality data are limited.

Platelet ADP-receptor antagonists for cardiovascular disease: past, present and future.

Aspirin is the foundation antiplatelet therapy for patients at risk of cardiovascular events. The thienopyridine, clopidogrel, is modestly more effective than aspirin and in patients with stroke seems to be as effective as the combination of aspirin and dipyridamole. The addition of clopidogrel to aspirin further reduces the risk of cardiovascular events in patients with acute coronary syndromes and those who undergo percutaneous coronary intervention, but uncertainty remains about whether this combination has incremental efficacy over clopidogrel monotherapy in patients with stroke or peripheral arterial disease.
