LVEF, left ventricular ejection fraction; LVFS, left ventricular fraction shortening; LVID(d), left ventricular internal dimension in diastole; LVID(s), left ventricular internal dimension in systole; HR, heart rate; dP/dt max, maximal slope of systolic pressure increment; dP/dt min, minimal slope of diastolic pressure decrement; LVEDP, left ventricular end-diastolic pressure. Data are means ± SEM. ∗ P < 0.05 versus the sham group; #P < 0.05 versus the MI group.
