*P < 0.05 vs control group (CTL); #P < 0.05 vs heart failure group (HF). AOD: aortic diameter; BNP: brain natriuretic peptide; E/A: early diastolic filling to atrial filling velocity ratio of mitral flow; EF: ejection fraction; FS: fractional shortening; IVST: interventricular septal thickness; LAD: left arterial diameter; LVDD: left ventricular end-diastolic dimension; LVDS: left ventricular end-systolic dimension; LVPW: left ventricular posterior wall.
