Background and rationale: excess body weight is an established cardiovascular risk factor. Current literature on the effects of cardiac rehabilitation (CR) in weight reduction has been inconclusive and none has provided results for an ongoing long term supervised exercise program beyond 3 months. We therefore undertake to determine the relationship of CR with ongoing supervised exercise program for over two years on weight reduction and fitness. Method: This is an observational study of 47 CR patients who were followed up for ≥24 months. Patients were assessed at their entry and exit of Phase II CR and at 12 and 24 months of Phase III programs. Results: No significant weight change occurred during either phase of CR for all pre-defined weight ranges in either Phase II or Phase III while exercise capacity increased by 3.3±1.1 METs (P<0.0001) and 0.6±1.24 METs, (p=0.1) respectively. Conclusion: The study demonstrates that CR even in a long-term setting does not significantly reduce weight amongst participants. To reduce excess weight as a risk factor, further interventions such as more exercise sessions or longer, more strenuous sessions, or dietary interventions should be considered.
