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 Multimodal Behavioral Intervention on Myocardial Perfusion—a Randomized Controlled Trial
Background Recent advances in drug therapy question as to the additional impact behavioral interventions may have on the prognosis of patients with clinical ly stable coronary heart disease ( CHD ) . Purpose The aim of the study was to evaluate the effects of a multimodal , behavioral intervention on myocardial perfusion ( MP ) and cardiac events , compared to st and ardized cardiologic care , in patients with stable CHD . Methods Seventy-seven CHD patients ( age 54.2 ± 6.9 years , male 87 % ) were r and omly assigned to a behavioral intervention plus st and ardized cardiologic care ( INT , n = 39 ) or st and ardized cardiologic care alone ( CO , n = 38 ) . MP was assessed by 201Thallium MP-scintigrams ( SPECT ) at baseline , after 2 , 3 , and 7 years , respectively . Subsequent cardiac events ( MI , PCI , CABG ) were assessed using the cardiologists ’ charts . Results Sixty-five patients ( 84 % ) completed the study . In all patients , the course of MP was significantly better in INT analysis of variance ( ANOVA group × time p = 0.001 ) ; this was also true for patients without subsequent PCI/CABG ( ANOVA group × time p = 0.002 ) . Incidence of cardiac events was significantly associated with INT ( 6 vs. 14 ; log rank test p = .047 ) . Conclusion The study suggests additional long-term benefits of a behavioral intervention  on myocardial perfusion and cardiac events in patients with stable CHD compared to st and ardized cardiologic care only
