Comparison between hybrid cardiac rehabilitation and center-based cardiac rehabilitation: a noninferiority randomized controlled trial

What the paper says

Cardiac rehabilitation (CR) is a cornerstone of heart disease (HD) management, enhancing functional capacity and quality of life. Hybrid cardiac rehabilitation (hCR), combining supervised center-based sessions with synchronous, real-time telerehabilitation at home, offers an alternative to conventional CR to overcome logistical barriers such as facility limitations, distance, and pandemic-related disruptions. This randomized controlled trial evaluated the noninferiority of hCR compared to standard CR in improving functional capacity in patients with chronic heart disease, including those with stable coronary artery disease. Seventy-five participants were randomized into two groups: the CR group, with exclusively center-based sessions, and the hCR group, with synchronous tele-rehabilitation sessions at home complemented by center-based sessions. Functional capacity was assessed using cardiopulmonary exercise testing, the six-minute walk test, and the wall squat test. Both groups showed significant improvements in functional outcomes, including walking distance (six-minute walk test), strength capacity (wall squat test), and cardiopulmonary exercise testing performance ( P < 0.001). The improvements in the hCR group were statistically noninferior to those in the CR group. These findings demonstrate that hCR provides an effective alternative to conventional CR while addressing practical challenges in access to care. The hCR protocol represents a viable solution for expanding rehabilitation options without compromising outcomes, particularly for patients facing logistical constraints or during emergencies such as pandemics.
