Stroke:抗血小板药物治疗可预防腔隙性卒中复发

2015-05-05 徐媛媛译 MedSci原创

腔隙性卒中约占缺血性卒中的25%,但最佳预防卒中复发的抗血小板治疗仍不明确。旨在评估抗血小板药物在腔隙性卒中后二次卒中复发的有效性。 我们在MEDLINE,Embase和Cochrane library系统中检索了与接受抗血小板治疗后的腔隙性卒中患者的卒中复发或死亡有关的随机对照试验。 我们收纳了17项试验,参与者42234名(平均年龄64.4岁,男性65%),随访时间从4周至3.5年。与安慰

腔隙性卒中约占缺血性卒中的25%,但最佳预防卒中复发的抗血小板治疗仍不明确。旨在评估抗血小板药物在腔隙性卒中后二次卒中复发的有效性。

我们在MEDLINE,Embase和Cochrane library系统中检索了与接受抗血小板治疗后的腔隙性卒中患者的卒中复发或死亡有关的随机对照试验。

我们收纳了17项试验,参与者42234名(平均年龄64.4岁,男性65%),随访时间从4周至3.5年。与安慰剂组相比,单独使用任何抗血小板药物与任何卒中复发(风险比 [RR] 0.77, 0.62-0.97, 2 研究)和缺血性卒中复发(RR 0.48, 0.30-0.78, 2 项研究)显著下降,但与任何卒中、心肌梗死或死亡的复合终点(RR 0.89, 0.75-1.05, 2 项研究)不相关。与阿司匹林相比,其他抗血小板药(噻氯匹定、西洛他唑和双嘧达莫)卒中复发率并没有降低(RR 0.91, 0.75-1.10, 3 项研究)。双联抗血小板治疗较单抗治疗没有获得明显效益(任何卒中 RR 0.83, 0.68-1.00, 3 项研究;缺血性卒中 RR 0.80, 0.62-1.02, 3 项研究;复合终点 RR 0.90, 0.80-1.02, 3 项研究)。

研究结果表明在所纳入的这些试验中,与安慰剂组相比,单独使用任何抗血小板药物足以预防腔隙性卒中后二次卒中复发。双联抗血小板治疗不应被用于长期卒中预防。
