Conclusions Exercise-based cardiac rehabilitation is effective at reducing important clinical outcomes in patients with coronary heart disease .
While our analysis was constrained by the quality of included trials and missing information about intervention components , there appears to be little differential effect of variations in exercise intervention , particularly on mortality outcomes .
Background While the clinical benefits of exercise-based cardiac rehabilitation are well established , there is extensive variation in the interventions used within these trials .
It is unknown whether variations in individual components of these exercise interventions provide different relative contributions to overall clinical outcomes .
This study aims to systematic ally examine the relationship between individual components of the exercise intervention in cardiac rehabilitation ( such as intensity and frequency ) and clinical outcomes for people with coronary heart disease .
Exercise after myocardial infarction: a controlled trial.
Six weeks after acute myocardial infa rct ion , 303 men were r and omly divided into exercise and control groups . The exercise group attended the hospital gymnasium twice weekly for a three-month supervised exercise course . Both groups were exercise tested before and after the course and at subsequent follow-up . The exercise group increased their physical fitness greatly compared with the control group . Eight per cent of the exercise group died during the period of follow-up , compared with 14 per cent of the control group ; this difference is not significant . There was an apparent improvement in mortality in those with inferior MI who completed the exercise course , which was not seen in those with MI in other sites . For many patients after MI progressive exercise is safe , improves physical fitness and may reduce mortality for those after inferior MI
