Coronary heart disease, a common cardiovascular disease, severely impacts patients' quality of life and survival rate globally. Cardiac rehabilitation, crucial for post-coronary heart disease recovery, significantly improves patient prognosis and quality of life. In recent years, with the development of information technology, telemedicine has emerged in cardiac rehabilitation for coronary heart disease patients, showing good prospects and providing more convenient rehabilitation support. However, differences in rehabilitation quality among centers affect the stability and accessibility of rehabilitation outcomes.

This scoping review aims to summarize existing research on telemedicine application in cardiac rehabilitation for coronary heart disease patients, providing a reference for healthcare professionals conducting remote cardiac rehabilitation.

Based on Arksey and O'Malley's scoping review framework, we searched multiple databases including Cochrane Library, PubMed, Web of Science, Embase, EBSCO, China Biology Medicine disc, China National Knowledge Infrastructure, Wanfang Data, and VIP Network from their inception to August 20, 2024. We screened, summarized, and analyzed the included literature.

We included 23 articles from 10 countries: 21 randomized controlled trials, 1 quasi-experimental study, and 1 qualitative study. Telemedicine carriers mainly included apps and remote monitoring systems. Telemedicine could guide rehabilitation exercise frequency and intensity, monitor arrhythmias, provide health education and social support. Most studies focused on coronary heart disease-related indicators, symptom assessment, quality of life, self-management, rehospitalization and mortality rates, resource costs, user experience (satisfaction and safety) , anxiety, depression, and physical activity levels.

Telemedicine enhances cardiac rehabilitation participation, exercise motivation, and medication adherence in coronary heart disease patients, improves sedentary behavior, and increases survival rate and quality of life. Although China's telemedicine is rapidly developing, it still faces challenges. Future improvements should involve optimizing remote cardiac rehabilitation platforms with AI technology, refining evaluation systems, and strengthening community service integration to enhance application effectiveness.
