摘要
目的探讨脑梗死二级预防中阿司匹林抵抗(AR)发生率,随访期AR与脑梗死复发及其他血管事件发生的关系。方法 600例脑梗死患者,入院当日开始服用阿司匹林,服用7~10 d后检测血小板聚集率,筛选出AR患者及敏感患者,并对患者进行6~24个月随访,观察脑梗死复发及其他血管事件发生情况,采用Logistic回归分析AR及血管事件发生的危险因素和预后。结果 600例脑梗死患者中有AR者150例(25.0%),敏感者450例(75.0%);AR组女性、糖尿病患者比例及血低密度脂蛋白(LDL)胆固醇水平均高于阿司匹林敏感组;糖尿病(OR=2.58,95%CI 1.37~4.85,P=0.003)、高LDL血症(OR=1.89,95%CI 1.21~2.93,P=0.005)为AR发生的独立危险因素;AR组随访期脑梗死复发率、心肌梗死发生率以及全因死亡率均高于阿司匹林敏感组;糖尿病(OR=2.47,95%CI 1.36~4.65,P=0.003)、动脉粥样硬化血栓型脑梗死(OR=2.13,95%CI 1.24~3.95,P=0.023)及AR(OR=3.86,95%CI 1.79~5.87,P=0.002)是随访期血管事件发生的独立危险因素,有AR者血管事件发生的风险增加3.86倍。结论脑梗死二级预防中AR发生率高,AR与脑梗死复发及其他血管事件的发生密切相关。
