Exercise-based cardiac rehabilitation likely results in a slight reduction in all-cause mortality in patients with coronary heart disease.
While the reduction in death risk from exercise-based cardiac rehab is slight in the short term, it is a statistically significant benefit that contributes to overall survival.
GoodQualifiesMEDIUM confidence
Exercise-based CR likely results in a slight reduction in all-cause mortality (risk ratio (RR) 0.87, 95% confidence interval (CI) 0.73 to 1.04; 25 trials; moderate certainty evidence).
Why this rating
Moderate certainty evidence from 25 RCTs, but the confidence interval crosses 1.0.
