Quality of life and behavioral compliance in cardiac rehabilitation patients: a longitudinal survey

Background Few data regarding inter-relations between health-related quality of life (HRQoL) and compliance are available. The aim of present study was to assess which aspects of HRQoL might predict patients’ behavioral compliance to medical suggestions and whether questionnaires might be useful for patients undergoing cardiac rehabilitation. Methods HRQoL and compliance were measured in 52 consecutive patients undergoing cardiovascular rehabilitation. The measurements were performed at the beginning, at the end of rehabilitation, and after 6 months follow-up. Baseline, demographic and HRQoL characteristics were linked to compliance by multiple regression modelling. Results Over time no significant differences between HRQoL and compliance scores were observed. Age (odds ratio (OR) 1.37, 95% confidence interval (CI) 1.08–2.45), number of taken drugs (OR=1.45; 95% CI: 1.02–2.11), anxiety score (OR=0.32; 95% CI: 0.15–1.02), depression score (OR=0.48; 95% CI: 0.06–0.78), and social health score (OR=1.09; 95% CI: 1.01–1.24), appeared to be independent predictors of compliance. Conclusion Older age, higher number of drugs, high social health score, and low anxiety and depression scores predict better behavioral compliance in cardiac rehabilitation patients.
