The dismal odds of surviving a sudden cardiac arrest

Windsor Star  

The shocking recent deaths of two prominent, apparently healthy men in their 40s underscores the “really, really poor” odds you’ll survive a sudden cardiac arrest — 10 per cent — when it happens outside a hospital.

Long-term dual antiplatelet therapy for secondary prevention of cardiovascular events in the subgroup of patients with previous myocardial infarction Oxford University Press


"Aims : Recent trials have examined the effect of prolonged dual antiplatelet therapy (DAPT) in a variety of patient populations, with heterogeneous results regarding benefit and safety, specifically with regard to cardiovascular and non-cardiovascular mortality. We performed a meta-analysis of randomized trials comparing more than a year of DAPT with aspirin alone in high-risk patients with a history of prior myocardial infarction (MI)."

Saxagliptin and Cardiovascular Outcomes in Patients with Type 2 Diabetes Mellitus The New England Journal of Medicine


"Background: Type 2 diabetes mellitus doubles the risk of major cardiovascular complications in patients with and in patients without established cardiovascular disease,1-3 such that the majority of patients with diabetes die of cardiovascular diseases.4 Although improved glycemic control has repeatedly been shown to reduce microvascular diabetic complications,5 uncertainty remains regarding whether any particular glucose-lowering strategy, or specific therapeutic agent, is safe from a cardiovascular standpoint or can actually lower cardiovascular risk. With the possible exception of trials of metformin6 and insulin,7 most reported trials to date evaluating the effects on cardiovascular outcomes of specific glucose-lowering strategies or medications either have been insufficiently powered or have shown no significant cardiovascular benefit8-10 or an increased risk of death11 or heart failure.12-15 Thus, there remains a strong clinical need to identify antihyperglycemic agents that are, at a minimum, safe and that can potentially reduce cardiovascular complications. Moreover, in 2008, the Food and Drug Administration and the European Medicines Agency simultaneously revised their approval processes for all new glucose-lowering therapies to require a demonstration of cardiovascular safety.16

Saxagliptin (Onglyza, AstraZeneca and Bristol-Myers Squibb) is a selective dipeptidyl peptidase 4 (DPP-4) inhibitor. 17 In phase 2–3 studies, treatment with saxagliptin improved glycemic control as compared with placebo and in pooled analyses reduced the risk of major cardiovascular events.18 The Saxagliptin Assessment of Vascular Outcomes Recorded in Patients with Diabetes Mellitus (SAVOR)–Thrombolysis in Myocardial Infarction (TIMI) 53 trial was designed to evaluate the safety and efficacy of saxagliptin with respect to cardiovascular outcomes in patients with diabetes mellitus who are at risk for cardiovascular events.
