Key result
Cardiac rehabilitation yields sustained improvements in physical and mental quality of life over 4 years.
Why the study?
Cardiac rehabilitation improves health-related quality of life, but evidence on long-term HRQoL changes after CR and their predictors was missing.
Does outpatient phase-II cardiac rehabilitation improve long-term health-related quality of life in patients with coronary heart disease?
Cohort (n=153)
No
Does outpatient phase-II cardiac rehabilitation improve long-term health-related quality of life in patients with coronary heart disease?
Phase-II cardiac rehabilitation is associated with significant improvements in physical and mental quality of life that are sustained for up to six years post-completion.

Supports durability of quality-of-life benefits after cardiac rehabilitation in coronary disease; extends prior observations but leaves open randomized confirmation of causality.
Background: Low health-related quality of life (HRQoL) is associated with adverse cardiovascular outcomes in coronary heart disease (CHD) patients. Cardiac rehabilitation (CR) improves HRQoL; however, evidence on long-term HRQoL changes after CR, and their predictors, is missing. Methods: A total of 153 patients with complete HRQoL data in the short-form (SF)-36 Health Survey at CR entry, discharge and follow-up were included. Using linear mixed-effects regression models for repeated time measurements, we examined predictors of follow-up HRQoL, including age and clinical characteristics. Results: Both physical (t = −5.66, p < 0.001) and mental (t = −2.06, p = 0.040) HRQoL improved significantly from CR entry to discharge, with improvements remaining stable over a mean follow-up of four years (range 2.4–6.1). Better functional capacity (6MWT) at CR entry predicted better physical HRQoL (t = 5.50, p < 0.001) and, with a trend, better mental HRQoL (t = 1.92, p = 0.056) at follow-up. A psychiatric diagnosis at CR entry predicted better mental HRQoL at follow-up (t = 3.85, p < 0.001). Conclusions: Improvements in HRQoL during CR remain stable during long-term follow-up. Levels of functional capacity appear to be relevant to both physical and mental HRQoL at follow-up.

Auschra et al. (2024) conducted a cohort in Coronary heart disease (n=153). Outpatient phase-II cardiac rehabilitation was evaluated on Physical health-related quality of life (HRQoL) improvement from cardiac rehabilitation entry to discharge (t = -5.66, p=<0.001). Physical and mental health-related quality of life improved significantly during cardiac rehabilitation and remained stable over a mean follow-up of 4 years, with better baseline functional capacity predicting long-term physical quality of life.
