Key result
Comprehensive outpatient cardiac rehabilitation in the UK resulted in a small overall increase in cardiorespiratory fitness of 0.52 METs (effect size d=0.59; 95% CI 0.58 to 0.60).
Why the study?
Does comprehensive outpatient cardiac rehabilitation improve cardiorespiratory fitness in UK patients?
Population
950 patients who completed cardiac rehabilitation at four UK centres
Design
Cohort
Follow-up
Post-rehabilitation (after 6 to 16 sessions)

Modest CRF gains with current UK volumes support limited efficacy; leaves open whether higher-intensity protocols improve outcomes.
Observational (n=950)
Yes
Does comprehensive outpatient cardiac rehabilitation improve cardiorespiratory fitness in UK patients?
Standardized Mean Difference: 0.59 (95% CI 0.58–0.6)
UK cardiac rehabilitation programs prescribe significantly lower exercise volumes than international trials, resulting in modest fitness gains that may explain reported inefficacy in reducing mortality and morbidity.
Sandercock et al. (2012) conducted an observational in Cardiac rehabilitation (n=950). Comprehensive outpatient cardiac rehabilitation was evaluated on Change in cardiorespiratory fitness (d 0.59, 95% CI 0.58 to 0.60). Comprehensive outpatient cardiac rehabilitation in the UK resulted in a small overall increase in cardiorespiratory fitness of 0.52 METs (effect size d=0.59; 95% CI 0.58 to 0.60).
