JAMA子刊:阿司匹林基础上,替格瑞洛vs氯吡格雷DAPT治疗中风的效果无差!

2021-12-16 MedSci原创 MedSci原创

阿司匹林与替格瑞洛或氯吡格雷相结合的DAPT优于单用阿司匹林,但在主要结果方面,2种方案之间没有发现统计学上的显著差异。

氯吡格雷和阿司匹林的双重抗血小板治疗(DAPT)能有效预防轻微缺血性卒中或短暂性脑缺血发作(TIA)后的复发卒中。近期,有专家提出,替格瑞洛联合阿司匹林治疗的证据正在出现,而这两种DAPT方案还没有被直接比较。

为了比较替格瑞洛和阿司匹林与氯吡格雷和阿司匹林在急性轻微缺血性卒中或TIA患者中预防复发卒中或死亡的效果,来自加拿大渥太华大学流行病学和公共卫生学院的专家开展了一项meta分析,结果发表在JAMA Neurology杂志上。

从MEDLINE、Embase和Cochrane等数据库搜索从开始到2021年2月的数据。研究选择随机的临床试验,这些试验招募了患有急性轻微缺血性卒中或TIA的成人,并在症状发生后72小时内提供上述干预措施,至少随访30天。

主要结果是90天内复发中风或死亡的综合结果。次要结果包括大出血、死亡率、不良事件和功能障碍。在30天时对主要结果进行了敏感性分析。

结果共筛选了4014条引文;纳入了5项随机临床试验。分析了22098名患者的数据,包括氯吡格雷和阿司匹林组的5517人,替格瑞洛和阿司匹林组的5859人,以及阿司匹林组的10722人。

与单纯使用阿司匹林相比,氯吡格雷和阿司匹林(HR=0.74;95% CrI,0.65-0.84)以及替格瑞洛和阿司匹林(HR=0.79;95% CrI,0.68-0.91)在预防复发卒中和死亡方面更好,分别降低26%与21%。氯吡格雷和阿司匹林与替格瑞洛和阿司匹林相比没有统计学上的显著差异(HR=0.94;95% CrI,0.78-1.13)。

三组治疗主要治疗结局的差异

同时,两种DAPT方案的大出血率都高于单用阿司匹林。与单独使用阿司匹林(HR=0.82;95% CrI,0.74-0.91)和替格瑞洛和阿司匹林(HR=0.85;95% CrI,0.75-0.97)相比,氯吡格雷和阿司匹林与功能障碍风险的降低有关。

综上,阿司匹林与替格瑞洛或氯吡格雷相结合的DAPT优于单用阿司匹林,但在主要结果方面,2种方案之间没有发现统计学上的显著差异。
