Effectiveness of Digital Cardiac Rehabilitation on Functional Capacity in Patients With Myocardial Infarction

The goal of this clinical trial is to learn if a digital health-supported cardiac rehabilitation program works to improve functional capacity, adherence, quality of life, and psychological status in cardiac patients. It will also learn about the effect of digital health support when added to conventional outpatient cardiac rehabilitation. The main questions it aims to answer are: Does a digital health-supported cardiac rehabilitation program improve functional capacity? How does digital health support affect patients' adherence to cardiac rehabilitation? How does the program affect patients' quality of life and psychological status? Researchers will compare digital health-supported cardiac rehabilitation combined with conventional outpatient cardiac rehabilitation to conventional outpatient cardiac rehabilitation alone to determine whether digital support improves functional, behavioral, and psychological outcomes in phase II cardiac patients. Participants will: Be randomly assigned to receive either digital health-supported hybrid cardiac rehabilitation in addition to conventional outpatient cardiac rehabilitation or conventional outpatient cardiac rehabilitation alone. Have their functional exercise capacity assessed using the Six-Minute Walk Test (6MWT) as the primary outcome measure. Complete assessments to evaluate cardiac rehabilitation adherence and engagement, health-related quality of life, and psychological status. Have resting heart rate and blood pressure monitored as part of the clinical assessment. Participants in the digital health-supported group will also use digital health tools for activity monitoring, exercise adherence, reminders, education, communication, and weekly telecoaching.

Inclusion Criteria: * Men and women aged 55-65 years. * Medically stable patients with a documented history of myocardial infarction who have been referred for Phase II outpatient cardiac rehabilitation. * Body mass index (BMI) between 30.0 and 39.9 kg/m² (Obesity Classes I and II). * Clearance from a cardiologist to participate in the prescribed exercise program. * Ability to walk independently, with or without an assistive device. * Ownership of a smartphone with stable internet access, or availability of a caregiver who can assist with smartphone use. * Willingness to follow the study procedures and provide written informed consent. Exclusion Criteria: * Unstable angina or decompensated heart failure. * Uncontrolled arrhythmias, uncontrolled hypertension, or any other contraindication to exercise training. * A recent major cardiac event or intervention that has not yet been medically stabilized. * Severe orthopedic, neurological, or pulmonary conditions that limit exercise testing or training. * Severe cognitive impairment or communication difficulties that prevent adequate cooperation. * Severe visual or hearing impairment that prevents safe use of the required digital technologies. * Inability or unwillingness to use the digital rehabilitation platform, even with caregiver assistance.
