Differential analysis of cardiac ultrasonic features in patients with different types of cardiomyopathy

Abstract

Objective To observe the differences of cardiac ultrasonic features in patients with different types of cardiomyopathy. Methods From January 2017 to September 2018, 55 patients with dilated cardiomyopathy (DCM group) and 55 patients with ischemic cardiomyopathy (ICM group) were enrolled in the study. All patients underwent echocardiographic examination. The echocardiographic parameters such as LVEDD, LVESD, LAD, RAD, RVD, EF, FS, SV and the changes of cardiac morphology were compared between the two groups. Results The levels of LVEDD, LVESD, LAD, RAD, RVD and SV in ICM group were lower than those in DCM group, and the levels of EF and FS were higher than those in DCM group (P<0.05). The incidence rates of left ventricular spherical shape change and diffuse wall motion reduction in DCM group were higher than those in ICM group, and the incidence rates of left ventricular arcuate shape change, segmental wall motion abnormality, round and thin apex of left ventricle, calcification of aortic root were higher than those in ICM group. The incidence rate of root calcification in ICM group was lower than that in ICM group (P<0.05). Conclusion There were significant differences in echocardiographic parameters and cardiac morphology between DCM and ICM. Most patients with DCM had both left and right ventricles enlarged at the same time, while patients with ICM had more severe aortic valve calcification.
