Key result
An 8-week cardiac rehabilitation program significantly improved maximal oxygen consumption by 2.7 mL/kg/min in male patients with myocardial infarction, with older patients (≥55 years) showing comparable or greater improvements than younger patients.
Why the study?
Does an 8-week cardiac rehabilitation program improve hemodynamic and metabolic outcomes differently in older (≥55 years) versus younger (<55 years) male patients following percutaneous coronary intervention for acute myocardial infarction?

Cardiac rehabilitation yields significant hemodynamic and metabolic improvements in older male patients post-myocardial infarction, suggesting aggressive CR programs are highly beneficial and safe for this demographic.
OBJECTIVE: To determine the age-related changes in cardiac rehabilitation (CR) outcomes, which includes hemodynamic and metabolic factors, in patients with myocardial infarction (MI). METHODS: CR was administered for 8 weeks to 32 men (mean age, 54.0±8.8 years) who underwent percutaneous coronary intervention for acute MI between July 2012 and January 2016. The exercise tolerance tests were performed before and after the CR. The results were stratified based on a cut-off age of 55 years. RESULTS: . The magnitude of the changes in the hemodynamic and metabolic variables before and after CR, based on age, did not differ between the groups; although, it tended to be greater among the older participants of this study's sample. CONCLUSION: Because the older participants tended to show greater hemodynamic and metabolic changes due to CR, a more aggressive CR program must be administered to elderly patients with MI.

Kong et al. (2017) conducted a cohort in Myocardial infarction (n=32). Cardiac rehabilitation vs. Baseline (pre-rehabilitation) was evaluated on Maximal oxygen consumption (VO2max) in mL/kg/min (MD 2.7, p=<0.01). An 8-week cardiac rehabilitation program significantly improved maximal oxygen consumption by 2.7 mL/kg/min in male patients with myocardial infarction, with older patients (≥55 years) showing comparable or greater improvements than younger patients.
