Efficacy of Home-Based Telerehabilitation Versus Center-Based Cardiac Rehabilitation on Cardiopulmonary Function and Exercise Capacity in Patients After Coronary Artery Bypass Grafting

Purpose: The objective is to compare the effects of a home-based telerehabilitation (HBTCR) program, traditional center-based cardiac rehabilitation (CBCR), and usual care on cardiopulmonary function and exercise capacity in patients after coronary artery bypass grafting (CABG). Methods: In this randomized controlled trial, 111 patients, 4 to 8 weeks after CABG surgery, were assigned to 12 weeks of HBTCR (n = 37), CBCR (n = 37), or to a control group (n = 37). The HBTCR group utilized wearable sensors and a mobile app for remote monitoring and coaching. The CBCR group underwent supervised on-site sessions. Primary outcomes were changes in peak oxygen uptake ( ) and 6-minute walk distance. Secondary outcomes included left ventricular ejection fraction, psychological status, and quality of life. Results: Among 101 completers, both HBTCR and CBCR groups showed significant improvements in (HBTCR: +5.1; CBCR: +4.8 mL/kg/min) and 6-minute walk distance (HBTCR: +85.2 m; CBCR: +81.5 m) versus control ( P < .001), with no difference between interventions. Significant improvements in left ventricular ejection fraction, psychological scores, and quality of life were also observed in both intervention groups compared with control ( P < .05). Adherence was high (HBTCR: 92.1%; CBCR: 85.3%) with no major adverse events. Conclusions: The findings suggest that an HBTCR program has similar efficacy as CBCR in improving cardiopulmonary function, exercise capacity, and patient-centered outcomes after CABG. An HBTCR program represents a viable, accessible alternative model for delivering comprehensive cardiac rehabilitation and secondary prevention.
