Key result
A 13.5-month physical training program in patients with healed myocardial infarction was associated with higher maximal oxygen intake (2.50 vs 2.07 L/min) and greater maximal A-V O2 difference.

May support training to boost post-MI oxygen uptake via extraction; extends observations but leaves causal effects open.

Does a physical training program improve maximal oxygen intake and hemodynamic parameters in patients with healed myocardial infarction?
Absolute Event Rate: 2.5% vs 2.07%
Long-term physical training in patients with healed myocardial infarction increases maximal oxygen intake primarily by enhancing peripheral oxygen extraction by working muscles.
Rousseau et al. (1973) conducted an observational in Healed myocardial infarction (n=14). Physical training program vs. Untrained group (2 months post-MI) was evaluated on Maximal oxygen intake (VO2 max). A 13.5-month physical training program in patients with healed myocardial infarction was associated with higher maximal oxygen intake (2.50 vs 2.07 L/min) and greater maximal A-V O2 difference.
