JAHA:阿哌沙班、达比加群,利伐沙班预防房颤患者卒中发生的有效性和安全型

2016-07-25 phylis 译 MedSci原创

背景:非维生素K拮抗剂这种口服抗凝剂是房颤患者卒中预防的一大进步;然而,临床试验中取得的成果不能转化到日常实践中。研究者通过与华法林对比,旨在评估利伐沙班、达比加群和阿哌沙班的有效性和安全性。方法和结果:使用美国大型保险数据库,研究者确定私人保险和医疗保险中,2010年10月1日和2015年6月30日期间,应用阿哌沙班、达比加群,利伐沙班,或华法林的非瓣膜性房颤患者。研究者采用1:1的倾向得分匹配

背景:非维生素K拮抗剂这种口服抗凝剂是房颤患者卒中预防的一大进步;然而,临床试验中取得的成果不能转化到日常实践中。研究者通过与华法林对比,旨在评估利伐沙班、达比加群和阿哌沙班的有效性和安全性。

方法和结果:使用美国大型保险数据库,研究者确定私人保险和医疗保险中,2010年10月1日和2015年6月30日期间,应用阿哌沙班、达比加群、利伐沙班或华法林的非瓣膜性房颤患者。研究者采用1:1的倾向得分匹配设为3组:阿哌沙班 vs华法林(n = 15,390),达比加群vs华法林(n = 28,614)和利伐沙班vs华法林(n = 32,350)。采用Cox比例风险回归分析,研究者发现,阿哌沙班与卒中或全身性栓塞低风险(HR 0.67,95% CI 0.46-0.98,P = 0.04)相关,但达比加群和利伐沙班发生卒中或全身性栓塞的风险与华法林类似(达比加群:HR 0.98,95% CI 0.76-1.26,P = 0.98;利伐沙班:HR 0.93,95% CI 0.72-1.19,P = 0.56)。阿哌沙班和达比加群严重出血的风险较低(阿哌沙班:HR 0.45,95% CI 0.34-0.59,P<0.001;达比加群:HR 0.79,95% CI 0.67-0.94,P<0.01),利伐沙班与华法林发生严重出血的风险类似(HR 1.04,95% CI 0.90-1.20 ])。所有非维生素K拮抗剂口服抗凝药与颅内出血风险较低相关。

结论:在非瓣膜性房颤患者中,阿哌沙班降低卒中和大出血风险,达比加群与卒中发生的风险类似,与较低的大出血风险相关,利伐沙班卒中和出血风险与华法林相似。
