Hypothesis
Does early and prolonged exercise training improve left ventricular remodeling in patients after myocardial infarction?
Conclusion
Starting exercise training earlier after a heart attack and continuing it for longer leads to better heart recovery.
Supporting Evidence
- Exercise training improves overall and cardiovascular-related mortality after myocardial infarction.
- Earlier initiation of exercise training leads to greater reductions in left ventricular volumes.
- Each week of delay in starting exercise requires an additional month of training for similar benefits.
Takeaway
If you start exercising soon after a heart attack and keep it up for a long time, your heart can get better faster.

Potential Biases
Trials did not report randomization procedures or blinding methods.
Limitations
The included studies were mostly low to moderate quality and predominantly involved younger males.
Participant Demographics
Mean age of participants was 55 years, primarily younger males with reduced systolic function.
