Short-duration exercise after MI promotes left ventricular ejection fraction (LVEF) and reduces mortality in aged mice. (a) Statistics of mouse body weight before and after 8-week swimming training (ST). (b) LVEF analysis. (c) Echocardiography of aged mice after 8-week ST. (d) Survival curves. ∗ P < 0.05 versus the sham group; # P < 0.05, ## P < 0.01 versus the MI-sedentary group; && P < 0.01 versus the MI + 15' ST group. N = 21–23 for survival rate analysis and N = 8–9 for other assessments.
