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 .
Effects of home-based rehabilitation on health-related quality of life and psychological status in Chinese patients recovering from acute myocardial infarction.
OBJECTIVE This study evaluated the effects of a home-based rehabilitation program for Chinese patients with myocardial infa rct ion in terms of health-related quality of life and psychological status . METHODS This was a r and omized , controlled trial with data collected at 2 university-affiliated public general hospitals in Xian ( Shaanxi Province , People 's Republic of China ) . One hundred and sixty patients with a myocardial infa rct ion were r and omly assigned to either the interventional group ( a home-based cardiac rehabilitation program using a self-help manual ) or the control group ( usual care ) . Health-related quality of life ( generic , Chinese Short Form 36-Item Health Survey ; disease-specific , Chinese Myocardial Infa rct ion Dimensional Assessment Scale ) and psychological status ( the Chinese Hospital Anxiety and Depression Scale ) were measured at baseline , program completion ( 6 weeks ) , and 3 and 6 months after hospital discharge . RESULTS Significant differences were evident in the main outcomes when the home-based group was compared with the usual care group at 6 weeks , 3 months , and 6 months . The home-based group had significantly higher scores on 4 of the 8 domains of the Chinese Short Form 36-Item Health Survey and on 3 of the 7 dimensions of the Chinese Myocardial Infa rct ion Dimensional Assessment Scale , with significantly lower scores on the anxiety , but not the depression , subscale of the Chinese Hospital Anxiety and Depression Scale . CONCLUSIONS A simple , home-based cardiac rehabilitation program for patients with acute myocardial infa rct ion , using a self-help manual , improves health-related quality of life and reduces anxiety . It appears feasible and acceptable , and does not produce inferior outcomes compared with usualcare in China
