Eur Heart J:老年房颤患者更宜应用阿派沙班

2014-02-27 高晓方 译 医学论坛网

一项多国研究表明,阿派沙班和华法林疗效不受房颤患者年龄影响,但阿派沙班在老年人群中的绝对获益优于华法林。论文2月20日在线发表于《欧洲心脏杂志》(Eur Heart J)。 此项研究共纳入18201例卒中风险升高的房颤患者,并随机给予华法林或阿派沙班治疗。在中位随访1.8年期间,利用Cox模型比较相对患者年龄的转归情况。纳入人群中<65岁、65~75岁和≥75岁者分别占30%、39%和31

此项研究共纳入18201例卒中风险升高的房颤患者,并随机给予华法林或阿派沙班治疗。在中位随访1.8年期间,利用Cox模型比较相对患者年龄的转归情况。纳入人群中<65岁、65~75岁和≥75岁者分别占30%、39%和31%。

结果显示,老年组患者的卒中、全因死亡和大出血发生率均显著升高(P<0.001)。在各年龄组患者中,阿派沙班预防卒中和减少死亡的效果均优于华法林。无论年龄如何,阿派沙班均与大出血、总体出血和颅内出血发生率较低具有相关性。在≥80岁患者中可得出一致结果。阿派沙班剂量与主要转归疗效无显著交互作用。
