JAMA Neurol:轻度房颤相关卒中抗凝策略选择——利伐沙班vs华法林钠

2017-09-12 zhangfan MedSci原创

研究认为,对于轻度房颤相关卒中患者,利伐沙班与华法林表现出相近的疗效和安全性

目前对于房颤(AF)相关的急性缺血性卒中患者,最佳抗凝策略仍不清楚。近日研究人员比较了利伐沙班和华法林钠在治疗AF相关急性缺血性卒中的疗效和安全性。

这项随机、多中心、开放、盲终点评估,比较II期试验从2014年4月持续至2015年12月,在韩国的14个医疗中心开展。参与者为5天内有轻度房颤相关卒中的、适合早期抗凝治疗患者。患者随机接受利伐沙班10 mg/d持续5天,之后进行15或20 mg/d的维持治疗或2-3国际标准化比值的华法林治疗,持续4周。研究的主要终点为4周后磁共振成像检查发现新缺血性病变或颅内出血,次要终点主包括主要终点的个体差异和住院时间。

共195名患者参与研究,其中184人完成试验,患者平均年龄70.4岁。利伐沙班组(n=95)以及华法林组(n=88)在主要终点(47 [49.5%] vs 48 [54.5%]; rr, 0.91; 95% CI, 0.69-1.20)以及主要终点的个体差异方面(新发缺血性病变: 28例 [29.5%] vs 31例 [35.6%];rr,0.83;95% CI,0.54-1.26; 新发颅内出血: 30例 [31.6%] vs 25例[28.7%];rr,1.10;95% CI,0.70-1.71)无显著差异。各组均发生1例临床缺血性卒中,所有颅内出血均为无症状性出血性改变。利伐沙班可减少患者住院时间(4.0天 vs 6.0 天)。

研究认为,对于轻度房颤相关卒中患者,利伐沙班与华法林表现出相近的疗效和安全性。
