摘要(Abstract)：

<正>近年来,我国经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)迅猛发展,每年的PCI例数明显增长,据不完全统计,2019年达100万例以上[1]。大量的证据表明,PCI不仅提高急性冠状动脉综合征患者的生存率,也缓解慢性心肌缺血患者的临床症状、改善其生活质量。但是,COURAGE研究[2]和ISCHEMIA研究[3]显示,稳定性冠心病患者早期PCI并不降低缺血性心血管事件风险。部分原因是由于医师目测或定量冠状动脉造影(quantitifying coranary angiography,QCA)分析获得的冠状动脉狭窄严重性并不能精确反映客观心肌缺血程度[4]。
