2017年9月,发表在《N Engl J Med》的一项由瑞典科学家进行的研究比较了比伐卢定和肝素治疗心梗的效果。

2017年9月,发表在《N Engl J Med》的一项由瑞典科学家进行的研究比较了比伐卢定和肝素治疗心梗的效果。

背景:根据目前的实践,包括桡动脉入路经皮冠状动脉介入(PCI),以及使用有效的P2Y12抑制剂,但没有有计划地使用糖蛋白IIb/IIIa抑制剂,行PCI的急性心梗患者多种抗凝策略的疗效比较尚未明确。

方法:在这项多中心、随机化、基于注册的、开放性临床试验中,研究者纳入正在行PCI或接受有效P2Y12抑制剂(替卡格雷、普拉格雷或坎格雷洛)治疗,但没有有计划地使用糖蛋白IIb/IIIa抑制剂的ST段抬高心梗(STEMI)或非STEMI(NSTEMI)患者。在主要通过桡动脉入路进行操作的PCI期间,这些患者被随机分配至接受比伐卢定或肝素。主要终点为随访180天期间任何原因死亡、心梗或大出血的复合。

结果:本试验共纳入6006例患者(3005例STEMI患者,3001例NSTEMI患者)。在180天时,比伐卢定组有12.3%(369/3004)的患者出现主要终点事件,肝素组有12.8%(383/3002)的患者出现主要终点事件(风险比,0.96;95%置信区间[CI],0.83~1.10;P=0.54)。STEMI患者与NSTEMI患者之间,及其它主要亚组之间的结果一致。比伐卢定组和肝素组发生心梗的比例分别为2.0%和2.4%(风险比,0.84;95% CI,0.60~1.19;P=0.33),发生大出血的比例分别为8.6%和8.6%(风险比,1.00;95% CI,0.84~1.19;P=0.98),确诊支架内血栓的比例分别为0.4%和0.7%(风险比,0.54;95% CI,0.27~1.10;P=0.09),死亡比例分别为2.9%和2.8%(风险比,1.05;95% CI,0.78~1.41;P=0.76)。

结论:在因心梗行PCI的患者中,比伐卢定使用者任何原因死亡、心梗或大出血的复合终点的发生率不低于接受肝素单药治疗的患者。(VALIDATE-SWEDEHEART ClinicalTrialsRegister.eu编号,2012-005260-10;ClinicalTrials.gov编号,NCT02311231)
