【Abstract】ObjectiveTo investigate the sensitivity and specificity of cardiac color Doppler ultrasound in the diagnosis of coronary heart disease （CHD）combined with heart failure （CHF）.MethodsEighty-eight patients with suspected CHDcombined with CHFadmited toour hospital from December 2021to December 2023 were included in the study according to the retrospective analysis method，and allof them underwent color Dopplerultrasonography. The diagnostic accuracy of cardiaccolor Doppler ultrasonography wasanalyzed using the results of coronary artery angiography as thegold standard，andthe diagnostic eficacyof cardiac color Doppler ultrasonography was analyzed by the ROCcurve diagram.ResultsEighty-eight patients with suspected CHD combined with CHF were selected.Seventy cases were positive and18 cases were negative as confirmed bythe gold standard.Color Doppler ultrasound detected 57 positive cases and 31 negative cases， with a detection sensitivity of 79 % ， a specificity of 89 % ， an accuracy of 81% ， a leakage rate of 21% ，and a misdiagnosis rate of 11% . Among them， there were 4O cases of patients with cardiac function grades ⌊～⌋⌊ and 17 cases of patients with cardiac function grade II. The lower the cardiac function clas，the highertheleftventricularejectionfraction（LVEF），andthe lowertheleftventricularend diastolicdimension （LVDd），left anterior descending artery （LAD），andE/Ea （P
