Multicenter Study
Twenty-five-year trends in myocardial infarction attack and mortality rates, and case-fatality, in six European populations.
Due to the burden of coronary heart disease (CHD), the monitoring of CHD trends is required. This study sought to examine the acute myocardial infarction (AMI) trends in attack and mortality rates, and in 28-day case-fatality, in six European populations during 1985-2010. ⋯ AMI event rates and inhospital case-fatality declined in 1985-2010 in almost all populations analysed. Prehospital case-fatality declined only in certain population groups, showing differences by sex. These results highlight the need of specific strategies in AMI prevention for certain groups and populations.

Randomized Controlled Trial Multicenter Study
Characterising and predicting bleeding in high-risk patients with an acute coronary syndrome.
In the Apixaban for Prevention of Acute Ischemic Events (APPRAISE-2) trial, the use of apixaban, when compared with placebo, in high-risk patients with a recent acute coronary syndrome (ACS) resulted in a significant increase in bleeding without a reduction in ischaemic events. The aim of this analysis was to provide further description of these bleeding events and to determine the baseline characteristics associated with bleeding in high-risk post-ACS patients. ⋯ NCT00831441.

Review
Surgical threshold for bicuspid aortic valve aneurysm: a case for individual decision-making.
The bicuspid aortic valve (BAV) affects 1-2% of the population and may be associated with important valvular disease and an increased risk of aortic root and/or ascending aortic aneurysm and dissection. BAV aortic aneurysm and dissection occur earlier in life than when these disorders are associated with a tricuspid aortic valve (TAV). Alterations in the aortic media and differences in aortic elastic properties and wall stress also accompany BAV aortopathy. ⋯ Guidelines have previously recommended prophylactic aortic surgery at a smaller aortic aneurysm size for patients with BAV compared with aneurysms in patients with a TAV. Recent guidelines have presented differing indications regarding the appropriate timing of prophylactic surgery for BAV aneurysms, giving the recommendation for surgery when the aortic root and/or ascending aortic exceeds 5.5 cm (unless certain factors are present), the same size for which TAV-associated aortic aneurysm surgery is recommended. We review the pathophysiology of BAV aortopathy, the clinical history of BAV ascending aortic disease, areas of uncertainty and make a case for a patient-centered, individualised decision regarding the optimal timing of aortic aneurysm surgery in BAV disease.
