JAMA Neurol:中风预防人群抗凝血剂颅内出血风险差异研究——阿司匹林vs口服抗凝剂

2018-08-14 zhangfan MedSci原创

研究认为,每日15-20mg利伐沙班会导致患者颅内出血风险增加,低剂量的利伐沙班或阿哌沙班则较为安全

非维生素K拮抗剂类口服抗凝血剂(NOACs)在非房颤人群中风预防中具有不错的应用前景。近日研究人员比较了NOACs与阿司匹林在中风预防过程中导致颅内出血的可能性。

本次研究为系统综述及荟萃分析研究,NOACs与阿司匹林关于颅内出血不良事件的随机研究纳入本次研究中,检索关键词包括新型口服抗凝剂、非维生素K拮抗剂口服抗凝剂、直接口服抗凝剂、达比加群、利伐沙班、阿哌沙班、依度沙班、华法林、华法林纳片、维生素K拮抗剂、阿司匹林、乙酰水杨酸、ASA,大出血、致命出血或颅内出血。研究的主要终点为NOAC与阿司匹林颅内出血风险比值比。

5个临床研究比较了1种及以上NOACs与阿司匹林颅内出血风险差异,总计39398名患者参与。相比于阿司匹林,每天一次性服用15-20mg的利伐沙班会增加颅内出血风险(2项研究,OR=3.31),而每日一次性服用10mg利伐沙班(3个研究,OR=1.43)或每次5mg每日2次服用阿哌沙班(1个研究,OR=0.84)不会增加患者颅内出血风险。

研究认为,每日15-20mg利伐沙班会导致患者颅内出血风险增加,低剂量的利伐沙班或阿哌沙班则较为安全。
