Stroke:房颤患者冠状动脉支架置入术后卒中预防方案

2019-07-15 xing.T MedSci原创

由此可见,直接口服抗凝血方案与较少的大出血和主要心血管不良事件相关,但维生素K拮抗剂与死亡和卒中发生率降低相关。这些结果表明,经皮冠状动脉介入治疗后房颤患者的抗血栓治疗方案需要个体化。

冠状动脉支架置入术后房颤患者需要平衡血栓栓塞和出血事件,特别是急性卒中的最佳抗血栓治疗策略仍然存在争议。近日,心血管疾病领域权威杂志Stroke上发表了一篇研究文章,研究人员进行了网络荟萃分析,以确定与冠状动脉支架术后房颤患者出血和血栓栓塞事件发生率最低相关的抗血栓形成治疗方案。

研究人员检索了PubMed、Scopus和Cochrane Central,确定了冠状动脉支架置入术后房颤患者的随机对照试验和观察性研究。感兴趣的结局是卒中、心肌梗塞、主要不良心脏事件、死亡和大出血。研究人员进行网络荟萃分析比较了文献中可用的抗血栓形成方案。

该分析纳入了三项随机和15项观察性研究,共有23478名参与者。中位随访时间为2年。网络荟萃分析表明,维生素K拮抗剂加单一抗血小板治疗或直接口服抗凝剂加单一抗血小板治疗是预防卒中的最有效方案。与维生素K拮抗剂方案相比,直接口服抗凝血方案与较低的大出血率相关。采用双重抗血小板治疗与较低的心肌梗死发生率相关。维生素K拮抗剂加双重抗血小板治疗与较低的死亡率,并且低剂量直接口服抗凝剂与主要心血管不良事件减少相关。

由此可见,直接口服抗凝血方案与较少的大出血和主要心血管不良事件相关,但维生素K拮抗剂与死亡和卒中发生率降低相关。这些结果表明,经皮冠状动脉介入治疗后房颤患者的抗血栓治疗方案需要个体化。
