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 .
Changes in cardiorespiratory fitness, psychological wellbeing, quality of life, and vocational status following a 12 month cardiac exercise rehabilitation programme.
OBJECTIVE To examine and evaluate improvements in cardiorespiratory fitness , psychological wellbeing , quality of life , and vocational status in postmyocardial infa rct ion patients during and after a comprehensive 12 month exercise rehabilitation programme . SUBJECTS The sample population comprised 124 patients with a clinical diagnosis of myocardial infa rct ion ( 122 men and two women ) . INTERVENTIONS 62 patients were r and omly allocated to a regular weekly aerobic training programme , three times a week for 12 months , and compared with 62 matched controls who did not receive any formal exercise training . A five year follow up question naire/interview was subsequently conducted on this population to determine selected vocational/lifestyle changes . RESULTS Significant improvements in cardiorespiratory fitness ( p < 0.01 - 0.001 ) , psychological profiles ( p < 0.05 - 0.001 ) , and quality of life scores ( p < 0.001 ) were recorded in the treatment population when compared with their matched controls . Although there were no significant differences in mortality , a larger percentage of the regular exercisers resumed full time employment and they returned to work earlier than the controls . Controls took lighter jobs , lost more time from work , and suffered more non-fatal reinfa rct ions ( p < 0.05 - 0.01 ) . CONCLUSIONS Regularly supervised and prolonged aerobic exercise training improves cardiorespiratory fitness , psychological status , and quality of life . The trained population also had a reduction in morbidity following myocardial infa rct ion , and significant improvement in vocational status over a five year follow up period
