Short-Duration Swimming Exercise after Myocardial Infarction Attenuates Cardiac Dysfunction and Regulates Mitochondrial Quality Control in Aged Mice

Figure 2

Short-duration exercise after MI inhibits cardiac fibrosis and apoptosis in aged mice. (a, b) Myocardial interstitial fibrosis determined by Masson trichrome staining. Black arrows indicate the ligation of left coronary artery. Scale bars, 50 μm. (c, d) Cardiomyocyte apoptosis determined by TUNEL staining. Scale bars, 30 μm. versus the sham group; , versus the MI-sedentary group; versus the MI + 15’ ST group. .
