RE-LY研究显示了应用达比加群和华法林预防非血管性房颤患者卒中发生的安全性和有效性。进一步评估常规治疗药物的安全性和有效性是非常重要的。

研究应用序贯队列研究,按照倾向指数配对比较两个商业健康保险数据库中的患者应用达比加群和华法林的有效性和安全性。从起始到中止,研究结束或研究预后发生(主要研究预后是卒中及严重出血),随访首次抗凝药的患者。应用比例风险回归分别分析每个数据源和结果。

在19189配对的达比加群和华法林的受试者中(平均年龄68岁,36%为女性),按照治疗随访(达比加群平均为5个月,华法林4个月)。分别有62名,69名患者发生卒中(HR = 0.77; 95 % CI = 0.54 to 1.09);分别354名,395名患者发生严重出血(HR = 0.75; 0.65 to 0.87)。各亚组间没有明显的差异,但是在年龄大于75岁(HR = 0.57; 0.33 to 0.97),或应用小于6个月(HR = 0.51; 0.19 to 1.42)的患者对卒中的预防效果,达比加群优于华法林。应用达比加群,年龄小于55岁(HR = 0.51; 0.30 to 0.87),CHADS2小于2(HR = 0.58; 0.44 to 0.77)的患者,严重出血发生最少。

结论:非血管性房颤患者常规治疗改善健康预后,达比加群优于华法林。
