摘      要：Objective To investigate the prognostic value of myocardial flow reserve(MFR)measured by SPECT myocardial blood flow(MBF)quantitative technique in patients with intermediate stenoses of coronary *** From September 2019 to May 2021,patients with intermediate stenoses(50%to 80%)identified by invasive coronary angiography in Fuwai Hospital,Chinese Academy of Medical Sciences,Fuwai Center China Cardiovascular Hospital,and TEDA International Cardiovascular Hospital were prospectively *** patients underwentaone-dayrest/stress SPECT myocardial perfusion imaging(MPI)and SPECT MBF *** radioactivity distribution of each segment of the MPI bullseye polar maps were obtained according to the standard 5-point method to obtain the summed stress score(SSS)and the summed difference score(SDS)to determine the existence of *** curve analysis was used to obtain the optimal prognostic cut-off value for MFR.
