在 ACC 2021年会上,韩国首尔圣玛丽医院介入心脏病专家Kiyuk Chang教授公布了一项随机对照试验结果,在急性心梗置入支架的患者中,与继续使用高强度双联抗血小板治疗(DAPT)方案相比,30天后改用阿司匹林+氯吡格雷的双抗方案在预防不良事件方面安全性和有效性更优。这是目前探讨双抗降级策略有效性和安全性的最大规模的研究,结果表明,对于已经接受了新一代支架置入的急性心梗患者,1个月后将双抗方案中的替格瑞洛降级为氯吡格雷更安全,更有效。 图1 急性心梗后患者血栓形成和出血风险变化趋势 本研究旨在比较氯吡格雷和替格瑞洛对稳定期急性心肌梗死(AMI)患者使用药物洗脱支架(DES)进行经皮冠状动脉介入治疗(PCI)的疗效和安全性。 TALOS-AMI是一项多中心、随机、开放标签研究,共纳入2590名AMI患者,在PCI手术后的第一个月内无不良事件发生。在PCI术后一个月,符合条件的患者按照1: 1比例被随机分配到1)阿司匹林100 mg+氯吡格雷75mg/天,或2)阿司匹林100 mg+替格瑞洛90 mg两次/天。根据出血学术研究协会(BARC)的标准,研究的主要终点事件是净临床不良事件
