研究目的:

在无严重冠脉狭窄的患者中,以冠脉造影血流储备分数>0.8 且负荷核素心肌灌注显像结果阳性为原发性微循环障碍性心肌缺血诊断金标准,评价冠脉造影血流储备分数分析系统(FlashAngio FFR System,FAS)测量舒张期微循环阻力指数(IDMR)诊断心肌缺血的价值与安全性。  

Objectives of Study:

To evaluate the accuracy of the FlashAngio FFR System (FAS) measuring index of diastolic microcirculatory resistance (IDMR) in the diagnosis of myocardial ischemia without severe coronary stenosis. The gold standard for the diagnosis of myocardial ischemia with primary microcirculatory disorders is coronary angiography-derived fractional flow reserve >0.8 with a positive myocardial perfusion imaging result.
