概括
冠状动脉旁路移植 (CABG) 显示出较好的长期存活率和较少的并发症,而不是对于左主冠状动脉疾病 (LMCAD) 的皮肤通冠状动脉干预 (PCI). 对于具有可接受的外科风险的LMCAD患者来说,CABG仍然是首选的治疗方法.
科学领域:
- 心血管医学 心血管医学
- 干预心脏病学 干预心脏病学
- 心脏外科手术 心脏外科手术
背景情况:
- 左主冠状动脉疾病 (LMCAD) 是一种危急的疾病,通常用冠状动脉旁路移植 (CABG) 或皮肤冠状动脉干预 (PCI) 来治疗.
- 之前对LMCAD重血管化策略的研究受样本大小和随访持续时间的限制.
- 这项研究提供了长期对CABG与PCI进行长达14年的LMCAD结果的比较.
研究的目的:
- 在LMCAD患者中比较CABG与PCI的长期疗效和安全性.
- 评估所有原因死亡率,心肌梗塞 (MI),中风和重复血管化率的差异.
- 为临床决策提供有关LMCAD.LMCAD最佳再血管化策略的信息.
主要方法:
- 一个省级数据库的回顾性分析,包括18岁以上的LMCAD患者接受CABG或PCI.
- 主要结局:全因死亡率. 二次结局:重新住院,心脏病发作,中风,重复血管化.
- 结果根据年龄,性别和并发症进行了调整,随访时间长达14年.
主要成果:
- 在1706名患者 (1180名CABG,526名PCI) 的队列中,CABG显示14年全因死亡率 (40.0%对58.4%;aHR0.58) 显著降低.
- 与PCI相比,CABG还显示心肌梗塞 (MI) 的发生率显著降低 (10.7%与22.3%相比;aHR 0.40) 和重复复血管化 (5.4%与16.3%相比;aHR 0.25).
- 所有比较都有利于CABG,p值<0.001.
结论:
- 冠状动脉旁路移植 (CABG) 为患有左主冠状动脉疾病 (LMCAD) 的患者提供了比皮肤冠状动脉干预 (PCI) 显著的长期生存益处.
- CABG与心肌梗塞和重复血管化的风险降低有关.
- 这些发现支持CABG作为可接受的外科风险的LMCAD患者首选的重血管化策略.
