概括
通过皮肤冠状动脉干预 (PCI) 和非心脏手术之前继续抗血小板治疗 (APT) 可以减少不良事件. 这种策略显示了较低的净不良临床事件 (NACE) 和主要不良心血管事件 (MACE) 发生率,而不会增加出血风险.
科学领域:
- 心脏病学 心脏病学
- 血管外科 血管外科
- 药理学 药理学是指药理学的学科.
背景情况:
- 在皮肤冠状动脉干预 (PCI) 一年内接受非心脏手术的患者的最佳抗血小板治疗 (APT) 仍然不清楚.
- 通常使用的是第二代药物排泄支架,需要仔细管理外科手术期间的抗血小板策略.
- 平衡支架血栓形成风险与手术出血并发症之间的平衡是一个关键的临床挑战.
研究的目的:
- 评估在非心脏手术期间继续APT的安全性和有效性,在最近的PCI患者中.
- 为了比较APT继续和停止策略之间的净不良临床事件 (NACE) 和重大出血的发生率.
- 为在这种高风险患者群体中管理抗血小板治疗提供基于证据的指导.
主要方法:
- 韩国的一项多中心前性注册研究包括在第二代药物释放支架植入后一年内接受非心脏手术的患者.
- 主要终点是30天的NACE,包括全因死亡,主要不良心血管事件 (MACE) 和重大出血.
- 倾向性得分调整用于控制APT继续和停止组之间的混变量.
主要成果:
- 在1130名符合条件的患者中,708人 (62.7%) 继续接受APT.
- 在倾向得分调整后,APT延续与NACE (3.7%与5.5%相比;调整后的OR,0.48;P=.019) 和MACE (1.1%与1.9%相比;调整后的OR,0.35;P=.046) 的明显较低率有关.
- 在两种策略之间,重大出血事件的发生率没有显著差异 (1.7%对2.6%;调整后OR,0.61;P=.273).
结论:
- 在第二代药物释放支架植入后一年内,在非心脏手术期间继续接受APT的患者与NACE和MACE的减少有关.
- 与停止APT相比,这种策略没有增加重大出血事件的风险.
- 这些发现表明,在这个患者队列中,APT延续的潜在好处是值得在临床实践中考虑的.

Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.
