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 .
Long-term effects of a comprehensive rehabilitation programme after myocardial infarction.
The aim of this study was to determine the long-term effects on myocardial infa rct ion ( MI ) patients of a six-month comprehensive rehabilitation programme ( CRP ) conducted by an interdisciplinary team regarding cardiac events , physical and psychological conditions , life habits , and cardiac health knowledge . The results of a multivariate analysis carried out five years after the MI showed that cardiac events and psychological condition were not significantly influenced by the CRP . However , it was found that the physical condition of the patients benefited from the CRP ;  self-reported physical fitness ( p < 0.002 ) and physical exercise test ( p < 0.007 ) . CRP participation was linked to significant modifications of life habits ( diet change ; p < 0.04 , sexual activity ; p < 0.000 ) . The cardiac health knowledge was significantly improved by participation in the CRP ( basic cardiac knowledge ; p < 0.005 ; knowledge about misconceptions ; p < 0.04 ) . In conclusion , CRPs have had positive long-term effects on physical condition , life habits and cardiac health knowledge . No such effects , however , were found regarding either cardiac events or psychological condition
