概括
双重抗血小板疗法 (DAPT) 在选择性冠状动脉旁路移植 (CABG) 后显著改善了存活率. 与阿司匹林单一治疗相比,DAPT降低了死亡率,尽管出血风险略有增加.
科学领域:
- 心血管外科心血管外科
- 药理学 药理学是指药理学的学科.
- 临床结果研究研究
背景情况:
- 双抗血小板疗法 (DAPT) 已为接受冠状动脉旁路移植 (CABG) 的急性冠状动脉综合征患者建立.
- 在选择性CABG程序中DAPT的有效性仍然不太清楚.
研究的目的:
- 评估DAPT与阿司匹林单疗对接受选择性CABG患者死亡率的影响.
- 为了比较二次结果,包括CABG后并发症和主要心血管不良事件.
主要方法:
- 2012-2015年CABG程序的单中心回顾性观察性研究.
- 主要结局:全因和心血管死亡率.
- 二次结局:CABG后的急性冠状动脉综合征,脑血管事故,主要心血管不良事件,出血和输血率.
主要成果:
- 与阿司匹林单一治疗相比,DAPT与明显较低的全因死亡率 (OR 0.43) 和心血管死亡率 (OR 0.30) 相关.
- 总体生存率在DAPT (97%) 与阿司匹林 (93%) 相比较高.
- 在CABG后发生的ACS,CVA和MACE的发病率相似;DAPT显示在医院出血率较高 (OR1.48),但输血需要相似.
结论:
- 在选择性CABG患者中使用DAPT与更高的生存率有关.
- 与阿司匹林单一疗法相比,DAPT在这个人群中显示,与阿司匹林单一疗法相比,所有原因和心血管死亡率降低.
- 在选择性CABG中,DAPT的好处超过了增加的出血风险,同样需要输血.

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.
