Background: The aim of this study was to evaluate the influence of residential (RCR) vs ambulatory (ACR) cardiac rehabilitation (CR) on health-related quality of life (QOL) connected with changes in exercise capacity of patients with coronary heart disease (CHD).
Methods and results: The 562 patients with CHD were studied: 313 participants in RCR and 249 participants in ACR. The examination was performed at the beginning of CR and after 8 weeks. QOL was assessed using the EuroQuol 5D (EQ-5D) and SF36 questionnaires. Exercise testing was performed with evaluation of workload during the last stage of the test and rate of perceived exertion intensity. In the first examination, patients from both groups did not differ significantly. After 8 weeks, a similar improvement in QOL was observed in both settings of CR according to EQ-5D and SF36 results. Health status was improved by 11.1% in the RCR group and by 10.4% in the ACR group. Last workload's intensity increased significantly by 32.1% in the RCR group and by 38.1% in the ACR group. The rate of perceived exertion intensity did not change despite the bigger workloads during the exercise test.
Conclusions: Comprehensive CR improves health-related QOL and exercise capacity without differences between residential and ambulatory models.
