Background: Cardiac rehabilitation (CR) is a widely recommended evidence-based intervention for patients with cardiovascular disease. However, the participation rate in CR has been reported to be low globally, mainly due to barriers in access to the CR center. We evaluated the feasibility and safety of a new remote real-time monitoring system for supervising home-based CR among elderly patients with heart failure (HF).
Methods: Hospitalized patients or outpatients followed for HF were enrolled. Patients received 12-week home-based CR under remote supervision using an integrated platform for telerehabilitation. Feasibility was evaluated by the participation and completion rates of the home-based CR sessions. Safety was assessed by adverse events during the sessions. All patients underwent baseline and 12-week assessment of exercise tolerance and lower extremity muscle strength.
Results: All 10 patients (mean age 76 ± 7 years; 60% male) who participated in the study completed the program without withdrawal during the study period. Median participation rate in the exercise sessions was 94.4% (interquartile range: 88.9-97.9%). While fatigue, common cold, and palpitation were observed, no serious cardiovascular events were reported. Six-minute walk distance significantly improved from 383 ± 94 m to 432 ± 83 m (p=0.003).
Conclusions: Home-based CR under real-time supervision was feasible and safe among elderly HF patients. Our study suggests that home-based CR using an integrated telerehabilitation platform may be a potential option for patients who are unable to participate in center-based CR due to geographic or social accessibility and physical barrier issues.
