Key result
Voluntary exercise post-MI increases ventricular dilation but improves survival to ~62% in severe remodeling.

In a murine model of myocardial infarction, voluntary exercise paradoxically increased ventricular chamber size but improved survival, especially in mice with severe initial ventricular dilation.
Ferrari et al. (2025) studied Myocardial Infarction (n=26). Voluntary exercise vs. Sedentary (no wheel access) was evaluated on Ventricular chamber size (p=<0.05). Voluntary exercise post-MI led to significantly larger ventricular chambers (p<0.05) but improved survival (62% vs 0%) in mice with severe ventricular dilation (>100 µL).
