CM, cardiomyopathy; DCM, dilated cardiomyopathy; HCM, hypertrophic cardiomyopathy; LVNC, left ventricular non-compaction; LVEDD, left ventricular end-diastolic dimension; LVESD, left ventricular end-systolic dimension; IVS, interventricular septum; PW, posterior wall; LV, left ventricle; LA, left atrium; e', early diastolic mitral annular tissue; E/e', ratio of early diastolic mitral inflow velocity to early diastolic mitral annular tissue velocity; RVSP, right ventricular systolic pressure.
Values are presented as mean±standard deviation unless otherwise indicated.
*p<0.05 compared to the group with no CM; †p<0.05 compared to the DCM group; ‡p<0.05 compared to the HCM group.
