为探讨阿司匹林在预防心脑血管病中的作用,检索了国外近年来的相关文献。在100项随机对照临床研究分析说明,阿司匹林在心脑血管的预防中具有相当的作用,可以使心脑血管事件减少1/6-1/3,并以小剂量(75mg~150mg/d)口服为宜,研究证明增大剂量只能增加副作用,不能增加疗效。并提出临床应用阿司匹林中应注意事项,以免滥用。 In order to investigate the role of aspirin in the prevention of cardiovascular and cerebrovascular diseases, the related literatures in recent years were retrieved. Analysis of 100 randomized controlled clinical studies shows that aspirin plays a significant role in the prevention of cardiovascular and cerebrovascular diseases and can reduce cardiovascular and cerebrovascular events by 1 / 6-1 / 3, and in small doses (75-150 mg / d) orally As appropriate, studies have shown that increasing the dose can only increase the side effects, can not increase the efficacy. And clinical application of aspirin should be noted in order to avoid abuse.
