NEJM:达比加群预防未确定来源栓塞性卒中患者的复发性卒中

2019-05-16 xing.T 网络

由此可见,对于近期未确定来源的栓塞性卒中患者,达比加群在预防复发性卒中方面并不优于阿司匹林。达比加群组的主要出血发生率不高于阿司匹林组,但达比加群组的临床相关非大出血事件更多。

隐源性卒中占缺血性卒中的20%至30%,并且大多数隐源性卒中被认为是栓塞性卒中和未确定来源的卒中。一项早期的随机试验表明,利伐沙班在预测来自未确定来源的栓塞性卒中后预防复发性卒中并不比阿司匹林更有效。达比加群是否能有效预防此类卒中后复发性卒中尚不清楚。

近日,顶级医学期刊NEJM上发表了一篇研究文章,研究人员进行了一项多中心、随机、双盲试验,达比加群剂量为150mg或110mg,每日两次,与剂量为100mg,每日一次的阿司匹林进行比较未确定来源的栓塞性卒中患者。该研究主要结果是复发性卒中。主要安全性结果是大出血。

该研究共有564个地区的5390名患者入选,他们随机分配接受达比加群(2695例患者)或阿司匹林(2695例患者)治疗。在中位随访19个月期间,达比加群组177例(6.6%)(每年4.1%)和阿司匹林组207例(7.7%)(每年4.8%)发生复发性卒中(风险比为0.85; 95%置信区间[CI]为0.69至1.03; P=0.10)。缺血性卒中发生在172名患者(每年4.0%)和203名患者(每年4.7%)中(风险比为0.84; 95%CI为0.68至1.03)。达比加群组77名患者(每年1.7%)和阿司匹林组64名患者(每年1.4%)出现大出血(风险比为1.19; 95%CI为0.85-1.66)。临床相关的非大出血分别发生在70名患者(每年1.6%)和41名患者(每年0.9%)中。 

由此可见,对于近期未确定来源的栓塞性卒中患者,达比加群在预防复发性卒中方面并不优于阿司匹林。达比加群组的主要出血发生率不高于阿司匹林组,但达比加群组的临床相关非大出血事件更多。
