【每日动态】新英格兰杂志:房颤抗凝治疗的新选择,新希望-Apixaban
Apixaban是Xa因子的直接抑制剂,不用检测INR,已有研究显示它可以有效预防矫形外科手术后的静脉血栓,那么他对房颤病人如何?
AVERROES研究共纳入5599例不适宜或不愿意用华法林治疗的房颤病人,将其随机分为apixaban组 (at a dose of 5 mg twice daily) 和aspirin组 (81 to 324 mg per day),一级终点是系统性栓塞和脑卒中。
病人的基本特征如下表:


病人不适宜用华法林的理由见下表:

两组人群结果差异:

apixaban组卒中和栓塞发生明显较阿司匹林组减少,两组出血事件相似。

结论:In patients with atrial fibrillation for whom vitamin K antagonist therapy was unsuitable, apixaban reduced the risk of stroke or systemic embolism without significantly increasing the risk of major bleeding or intracranial hemorrhage.
