Effects of physical training on cardiovascular function following myocardial infarction
Why the study?
Does a high-intensity exercise program improve cardiovascular function compared to a low-intensity exercise program in patients post-myocardial infarction?
Population
79 subjects under 54 years old, 3 to 12 months post-myocardial infarction.
Comparison
High-intensity exercise program for 12 months vs Low-intensity exercise program (LIE) for 12 months
Design
RCT, assigned randomly
Follow-up
12 months

Implication
Supports high-intensity exercise in post-MI rehabilitation; extends RCT evidence for sustained superiority over low-intensity training.
Structured PICO
Does a high-intensity exercise program improve cardiovascular function compared to a low-intensity exercise program in patients post-myocardial infarction?
P
Population
79 subjects under 54 years old (mean age 45.0 +/- 4.7 years), 3 to 12 months (mean 7.1 +/- 3.2 months) post-myocardial infarction.
I
Intervention
High-intensity exercise program (HIE) for 12 months
C
Comparator
Low-intensity exercise program (LIE) for 12 months
O
Outcome
Cardiovascular function (cardiac output, stroke volume, predicted maximal O2 intake, heart rate) measured during graded bicycle ergometer exercise at 6 and 12 monthssurrogate
Sustained high-intensity exercise training over 12 months significantly improves maximal oxygen intake and stroke volume in post-myocardial infarction patients compared to low-intensity exercise.
