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 .
Quality of life and return to work 5 years after coronary artery bypass surgery. Long-term results of cardiac rehabilitation.
BACKGROUND Rehabilitation is an important part of the treatment of patients with ischemic heart disease . Therefore , many patients undergoing coronary artery bypass surgery ( CABS ) also participate in cardiac rehabilitation programs . This study was conducted to investigate whether rehabilitation influences quality of life and work status after CABS . METHODS Consecutive patients undergoing elective CABS were r and omly assigned to a rehabilitation group ( R , N = 119 ) and a hospital-treatment group ( H N = 109 ) . All patients received usual medical care .  Group R participated in a rehabilitation program based on exercise and counseling . The follow-up time was 5 years . The measured domains of health-related quality of life were heart symptoms , functional class , exercise capacity , use of medication , depression , the patients ' perception of health , and overall life situation . The Nottingham Health Profile as a measure of perceived distress was used . RESULTS Symptoms , use of medication , exercise capacity , and depression scores did not differ between groups R and H. Five years after the CABS , the patients in group R reported less restriction in physical mobility on the Nottingham Health Profile than patients in group H ( P = 0.005 ) , and more patients in group R than in group H perceived their health ( P = 0.03 ) and overall life situation ( P = 0.02 ) as good . The increase in the proportion of subjects working was higher in group R than group H at 3 years after the CABS ( P = 0.02 ) , but not at other follow-up times . CONCLUSION A cardiac rehabilitation program in conjunction with usual medical care after CABS may induce a perception of improved health . The influence on return to work is limited
