*P<0.05 versus control group, #P<0.05 versus LVDD, &P<0.05 versus HFpEF. LVDD, left ventricular diastolic dysfunction; HFpEF, heart failure with preserved ejection fraction; HFrEF, heart failure with reduced ejection fraction; Te-SD, standard deviation of time to peak early diastolic strain rate; Ts-SD, standard deviation of time to peak systolic strain.
