Circulation:肾功能恶化的患者可以服用利伐沙班降低卒中或全身性栓塞的风险

尽管新型抗凝药物在临床上被快速采用,但这些新型药物与华法林相比,对于肾功能恶化(WRF)患者的结果还是未知的。该研究的目的是确定在ROCKET AF试验(利伐沙班,每日一次,口服,在房颤患者中直接因子Xa抑制剂 vs 维生素K对于预防卒中和栓塞的试验)的主要疗效(卒中或全身性栓塞)和安全终点(大出血和不严重的临床相关出血)是否与WRF患者服用利伐沙班和服用华法林的结果不同。排除了缺少至少一次随访肌

尽管新型抗凝药物在临床上被快速采用,但这些新型药物与华法林相比,对于肾功能恶化(WRF)患者的结果还是未知的。该研究的目的是确定在ROCKET AF试验(利伐沙班,每日一次,口服,在房颤患者中直接因子Xa抑制剂 vs 维生素K对于预防卒中和栓塞的试验)的主要疗效(卒中或全身性栓塞)和安全终点(大出血和不严重的临床相关出血)是否与WRF患者服用利伐沙班和服用华法林的结果不同。

排除了缺少至少一次随访肌酐测量患者(n=1624)后,该研究包括了所有剩余的患者(n=12612),将其随机分配到利伐沙班或剂量调整的华法林组。在治疗的WRF患者(研究过程中任一时间点测量肌酐清除率减少>20%)通过一个随时间变化的协变量的Cox比例风险模型进行评估。

在肾功能稳定(n=9292)和WRF(n=3320)患者中基线特征是相似的。卒中或全身性栓塞,心肌梗死,出血的发生率也相似,但WRF患者与稳定肾功能患者相比,出现血管性死亡的发生率较高(每100人年2.2 vs 11.41例事件; P=0.026)。随机分配接受利伐沙班的WRF患者与那些服用华法林的患者相比,卒中或全身性栓塞的发生率较低(每100人年1.54 vs 3.25例事件),而在接受利伐沙班的肾功能稳定患者中没有发生这种情况(相互作用P=0.050)。在接受华法林 vs 利伐沙班的WRF患者中,发生大出血或不严重的临床先关的大出血没有差异。

在正接受治疗的WRF患者中,与华法林相比,利伐沙班可以降低卒中和全身性栓塞的风险,也并没有增加在复合出血事件率。
