阿司匹靈對心血管疾病的初級預防無效

Dr Gerry Fowkes根據Aspirin for Asymptomatic Atherosclerosis (AAA)試驗報告顯示，在無症狀的動脈硬化的健康人身上，使用低劑量的阿司匹靈來預防心血管疾病並沒有顯著的效果，但用在中風或心血管疾病後預防則有降低再發的機率的效果。

clipped from www.medscape.com August 30, 2009 (Barcelona, Spain) — The use of low-dose aspirin in the primary prevention of cardiovascular events in healthy individuals with asymptomatic atherosclerosis is currently not warranted, according to the lead researcher of a large "real-world" study presented today at the European Society of Cardiology (ESC) 2009 Congress. In the randomized trial of 3350 subjects deemed at high risk for cardiovascular and cerebrovascular events because of a low ankle-brachial index (ABI) (<0.95), aspirin had absolutely no effect on reducing events compared with placebo, Dr Gerry Fowkes (University of Edinburgh, Scotland) reported on behalf of the University of Edinburgh, Scotland) reported on behalf of the Aspirin for Asymptomatic Atherosclerosis (AAA) trialists.
