概括
冠状动脉旁路移植 (CABG) 后的双抗血小板治疗 (DAPT) 降低了死亡率和主要心脏不良事件,但与单一抗血小板治疗 (SAPT) 相比,增加了出血风险. 与提卡格勒勒或普拉苏格勒 (DAPT-T/P) 联合的DAPT与克洛皮多格勒 (DAPT-C) 相比,进一步降低了死亡率.
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:
- 冠状动脉旁路移植 (CABG) 是复杂冠状动脉疾病的标准治疗方法.
- 阿司匹林通常用于CABG后,但最佳的抗血小板策略仍在争论中.
- 存在不同的双重抗血小板治疗 (DAPT) 方案,包括用克洛皮多格勒 (DAPT-C) 与提卡格勒或普拉苏格勒 (DAPT-T/P) 的方案.
研究的目的:
- 评估CABG后不同抗血小板治疗方案的疗效和安全性.
- 为了比较双抗血小板治疗 (DAPT) 与单抗血小板治疗 (SAPT).
- 为了比较DAPT与蒂卡格勒勒/普拉苏格勒 (DAPT-T/P) 与克洛皮多格勒 (DAPT-C).
主要方法:
- 按照PRISMA指南进行系统审查和元分析.
- 在主要数据库 (PubMed,Embase,Cochrane) 进行文献搜索.
- 包括38项研究,包括77,447名CABG患者;数据采用随机效应模型汇总.
主要成果:
- 与SAPT相比,DAPT显著降低了全因死亡率,心血管死亡率以及主要的心脏和脑血管不良事件 (MACCE).
- 与SAPT相比,DAPT与较大和较小出血率的增加有关.
- 与DAPT-C相比,DAPT-T/P显著降低了全因和心血管死亡率,其他结果没有显著差异.
结论:
- DAPT提高了生存率,并减少了CABG后的MACCE,特别是在急性冠状动脉综合征患者中,但增加了出血风险.
- 与DAPT-C相比,DAPT-T/P提供了优越的死亡率降低.
- 个性化抗血小板治疗选择至关重要,平衡CABG患者的缺血和出血风险.

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.
