摘要
目的系统评价不同血压靶目标值对心血管事件的影响。方法计算机检索PubMed、EmBase、Cochrane图书馆、中国知网、中国生物医学文献数据库(CBM)等中英文数据库,筛选不同血压靶目标值对心血管事件影响的随机对照试验,运用RveMan 5.3软件对纳入资料进行Meta分析。结果共纳入7项随机对照试验,共32 315例病人。与标准降压(<140/90 mmHg)比较,强化降压(<130/80 mmHg)心肌梗死风险比(HR)为0.84,卒中HR为0.82,心力衰竭HR为0.77,并未发现强化降压降低或增加全因死亡及心血管死亡的风险。结论强化降压与标准降压相比,可降低心肌梗死、卒中、心力衰竭的风险。
