  1. Values are means ± SEM of control (C, n = 10), infarcted (MI, n = 9) and infarcted and trained (MIT, n = 9) groups. Absolute masses of the cardiac chambers were indexed by the respective body mass (relative, mg/g of body mass)
  2. RV, right ventricle. LV, left ventricle
  3. *p < 0.05 vs. C. †p < 0.05 vs. MI, by 1-way ANOVA plus Tukey’s post hoc
