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 .
Home-based cardiac rehabilitation is an attractive alternative to no cardiac rehabilitation for elderly patients with coronary heart disease: results from a randomised clinical trial
Objective To compare home-based cardiac rehabilitation ( CR ) with usual care ( control group with no rehabilitation ) in elderly patients who declined participation in centre-based CR . Design R and omised clinical trial with 12 months follow-up and mortality data after 5.5 years ( mean follow-up 4½ years ) . Setting Rehabilitation unit , Department of Cardiology , Copenhagen , Denmark . Participants Elderly patients ≥65 years with coronary heart disease . Intervention A physiotherapist made home visits in order to develop an individualised exercise programme that could be performed at home and surrounding outdoor area . Risk factor intervention , medical adjustment , physical and psychological assessment s were offered at baseline and after 3 , 6 and 12 months . Main outcome measurements The primary outcome was 6 min walk test ( 6MWT ) . Secondary outcomes were blood pressure , body composition , cholesterol profile , cessation of smoking , health-related quality of life ( HRQoL ) , anxiety and depression . Results 40 patients participated . The study population was characterised by high age ( median age 77 years , range 65–92 years ) and high level of comorbidity . Patients receiving home-based CR had a significant increase in the primary outcome 6MWT of 33.5 m ( 95 % CI : 6.2 to 60.8 , p=0.02 ) at 3 months , whereas the usual care group did not significantly improve , but with no significant differences between the groups . At 12 months follow-up , there was a decline in 6MWT in both groups ; −55.2 m ( 95 % CI : 18.7 to 91.7 , p<0.01 ) in the home group and −52.1 m ( 95 % CI : −3.0 to 107.1 , p=0.06 ) in the usual care group . There were no significant differences in blood pressure , body composition , cholesterol profile , cessation of smoking or HRQoL after 3 , 6 and 12 months follow-up . Conclusions Participation in home-based CR improved exercise capacity among elderly patients with coronary heart disease , but there was no significant difference between the home intervention and the control group . In addition , no significant difference was found in the secondary outcomes . When intervention ceased , the initial increase in exercise capacity was rapidly lost
