AHA 2013:房颤患者用依度沙班疗效不劣于华法林(ENGAGE AF-TIMI 48研究)

2013-11-22 高晓方 译 医学论坛网

于AHA 2013科学年会公布的ENGAGE AF-TIMI 48研究显示,对于房颤患者预防卒中或系统性栓塞而言,大、小剂量(60 mg和30 mg)依度沙班均不劣于华法林,并且两种剂量依度沙班所致的大出血发生率显著低于华法林。研究论文还发表于《新英格兰医学杂志》(NEJM)。 此项研究共纳入21105例中、高危房颤患者,并将其随机分入高、低剂量依度沙班(60和30 mg)组或华法林组。

此项研究共纳入21105例中、高危房颤患者,并将其随机分入高、低剂量依度沙班(60和30 mg)组或华法林组。华法林组患者的中位用药时间为907天,并且INR介于2.0~3.0的时间占68.4%。平均随访时间为2.8年。主要有效性终点为卒中或系统性栓塞,主要安全性终点为大出血。

结果显示,与华法林组相比,高剂量依度沙班组患者的出血性卒中风险降低46%,低剂量依度沙班组则降低53%(P<0.001)。两种剂量依度沙班组患者的心血管死亡率均显著低于华法林组。高剂量依度沙班组的缺血性卒中发生率与华法林组相似,低剂量依度沙班组则较高。与华法林相比,高、低剂量依度沙班组的大出血危险比分别为0.79和1.07。
