Comparison of Conventional and Tele-cardiac Rehabilitation

This prospective, patient-preference, controlled study aimed to investigate the comparative effects of tele-cardiac rehabilitation (TCR) and hospital-based cardiac rehabilitation (HBCR) on functional capacity, fear of activity, and quality of life in patients with coronary artery disease (CAD). The study was conducted between February 2022 and May 2024 at the university's Physical Medicine and Rehabilitation Department. Patients were enrolled based on specific inclusion and exclusion criteria, including stable CAD and adequate technological access for TCR participation. The study design allowed participants to choose between TCR and HBCR after receiving information about both programs, reflecting real-life clinical decision-making scenarios. Both rehabilitation programs lasted for four weeks, with three exercise sessions per week. In the HBCR group, patients underwent supervised exercise sessions in the cardiac rehabilitation (CR) unit, including individualized aerobic and resistance training. Aerobic exercises were based on the patient's peak VO2 from a baseline cardiopulmonary exercise test (CPET), aiming to achieve 60-80% of the maximum heart rate. Resistance training involved the use of elastic bands targeting major muscle groups, with a progressive increase in repetitions based on patient tolerance. The TCR group received a home-based exercise program that included aerobic and resistance training. Aerobic exercises, such as walking, were performed for 30 minutes, three times a week, monitored via a Polar H9 heart rate device. Patients were instructed to maintain heart rates within the same range as the HBCR group. Resistance exercises were similar to those in the HBCR group, using elastic bands provided at the beginning of the study. Weekly remote follow-ups were conducted via phone calls to assess adherence, review heart rate data, and provide encouragement. Initial and final evaluations included the CPET, the Coronary Artery Disease-Specific Activity Fear Scale (AKKOR-KAH), and the WHOQOL-BREF Quality of Life Questionnaire. Outcome measures assessed changes in peak oxygen consumption (VO2 max), exercise capacity, quality of life, and fear of activity.
