Objective: This research was aimed at determining research hotspots and major topics in the field of international home-based cardiac rehabilitation (HBCR) over the past 20 years, and exploring future trends in HBCR. Methods: A total of 757 research articles from 2002 to 2022, with themes of home-based cardiac rehabilitation, were included in the core collection database of Web of Science. CiteSpace software was used for literature metrology and visualization analysis. Results: (1) The total number of research articles on HBCR is increasing. (2) Research hotspots in HBCR include the effectiveness of rehabilitation after coronary heart disease or heart failure; quality of life; mental health; and home rehabilitation after COVID-19. (3) Research trends in HBCR include wearable intelligent technology; telerehabilitation; lifestyle interventions; and home-based rehabilitation prescriptions for exercise, nutrition, psychology and continuous management. Conclusion: The effects of HBCR have been continuously verified. Research has focused primarily on secondary prevention and rehabilitation after coronary heart disease and heart failure. More attention must be paid to improving patients' quality of life by HBCR. Telerehabilitation based on wearable intelligent technology, home-based lifestyle interventions and continuous management are future trends of HBCR development.
