Abstract

Objective To investigate the value of echocardiography in the differential diagnosis of ischemic cardiomyopathy (ICM) and dilated cardiomyopathy (DCM).Methods One hundred and seventy-five cases were enrolled into this study who had been diagnosed with the symptoms of heart failure, low ejection fraction and enlargement of the heart indicated by cardiac ultrasound.After the remission of heart failure,they underwent selective coronary angiography (CAG)and were definitely diagnosed with ICM or DCM. The ICM group consisted of 94 patients and the DCM group 81 patients. Two dimensional color Doppler ultrasound echocardiography was used to find the difference in cardiac morphology, hemodynamics and ventricular function.Results There was significant difference in ultrasound echocardiography between the two groups (P<0.05 or P<0.01).Conclusions There is significant difference between ischemic cardiomyopathy and dilated cardiomyopathy in ultrasound echocardiography. In DCM, the chambers are relatively larger, and blood flow is faster.

Key words
