BMJ:直接口服抗凝药与华法林的风险和益处比较

2018-07-06 xing.T MedSci原创

总的来说,与华法林相比,阿哌沙班被认为是最安全的药物,其降低了大出血、颅内出血和胃肠道出血的风险。然而,与华法林相比,利伐沙班和低剂量阿哌沙班与全因死亡风险增加有关。

近日,顶级杂志BMJ上发表了一篇研究文章,研究人员旨在评估与华法林相比,直接口服抗凝剂(DOACs)与出血风险、缺血性卒中、静脉血栓栓塞和全因死亡率之间的关联。

该研究为前瞻性开放队列研究,132231名参与者服用华法林,7744名参与者服用达比加群,37863名参与者服用利伐沙班和18223名参与者服用阿哌沙班,在进入研究之前12个月未接受抗凝治疗,在2011年至2016年间参与者分为103270例房颤患者和92791例无房颤患者。该研究的主要结局指标为引起入院或死亡的大出血,还分析了出血的特定部位和全因死亡率。

在房颤患者中,与华法林相比,服用阿哌沙班与大出血(校正风险比为0.66,95%置信区间为0.54-0.79)和颅内出血(0.40,0.25-0.64)风险降低相关;达比加群与颅内出血风险降低有关(0.45,0.26-0.77)。在服用利伐沙班(1.19,1.09-1.29)或较低剂量的阿哌沙班(1.27,1.12-1.45)的患者中可观察到全因死亡的风险增加。在无房颤的患者中,与华法林相比,服用阿哌沙班与大出血(0.60,0.46-0.79)、任何消化道出血(0.55,0.37-0.83)和上消化道出血(0.55,0.36-0.83)风险降低有关;利伐沙班与颅内出血风险降低有关(0.54,0.35-0.82)。在服用利伐沙班(1.51,1.38-1.66)和较低剂量阿哌沙班(1.34,1.13-1.58)的患者可观察到全因死亡的风险增加。

总的来说,与华法林相比,阿哌沙班被认为是最安全的药物,其降低了大出血、颅内出血和胃肠道出血的风险。然而,与华法林相比,利伐沙班和低剂量阿哌沙班与全因死亡风险增加有关。
