Infarct size, echocardiography, and hemodynamic evaluation. A: example of a left ventricular (LV) infarct (dotted line) compared with a sham heart at 12 wk after myocardial infarction (MI). Sham sedentary (Sham-Sed), n = 6; sham exercise-trained (Sham-ExT), n = 5; chronic heart failure sedentary (CHF-Sed), n = 6; and CHF-ExT, n = 4. B: ejection fraction (EF) at 3 time points: before MI or sham surgery, 4 wk after surgery, and after exercise training (ExT). Sham-Sed, n = 5; Sham-ExT, n = 6; CHF-Sed, n = 6; CHF-ExT, n = 5. C: representative M-mode, long-axis, and two-dimensional echocardiography images of the LV from each group. D: representative traces (1 s) of left ventricular pressure (LVP) and left ventricular dP/dt. Sham-Sed, n = 5; Sham-ExT, n = 6; CHF-Sed, n = 6; CHF-ExT, n = 7. n = no. of mice.
