Lancet:心血管事件风险一般的老年人群不需要服用阿司匹林

研究认为,对于心血管事件风险一般的老年人群不需要使用阿司匹林作为一级预防手段

阿司匹林在血管事件一级预防中的应用仍有争议。近日研究人员比较了阿司匹林和安慰剂在首次血管事件一般风险人群中的效果和安全性。

ARRIVE研究为多中心、随机、双盲、安慰剂对照研究,在7个国家开展。55岁以上男性或60岁以上女性参与,参与者心血管事件风险与一般人群相当,随机接受100mg阿司匹林或安慰剂,每天1次。研究的主要终点为心血管死亡、心肌梗死、不稳定心绞痛、中风或短暂性缺血发作。安全性终点为出血事件和其他不良事件。

12546人参与研究,其中阿司匹林组6270人,安慰剂组6276人,平均随访60个月。意向分析显示,阿司匹林组269人(4.29%)发生终点事件,安慰剂组为281人(4.48%,HR=0.96)。阿司匹林组61人(0.97%)与安慰剂组29人(0.46%,HR=2.11)出现中度出血,其他严重不良事件率(20.19% vs 20.89%)、总不良事件率(82.01% vs 81.72%)差异不显著。总体治疗相关的不良事件率较低,组间死亡率差异不显著。

研究认为,对于心血管事件风险一般的老年人群不需要使用阿司匹林作为一级预防手段。
