Abstract: Background　In China，there are a large number of cardiovascular disease patients，which highlights the important role of cardiac rehabilitation in improving patients' prognosis and reducing their treatment burden. To promote domestic development of cardiac rehabilitation，it is necessary to review the international research hotspots in this field regularly. Objective　To understand the distribution of countries and institutions studying cardiac rehabilitation, and hot topics of cardiac rehabilitation research since 2000，providing scientific evidence for carrying out relevant research in China. Methods　With "(cardiac or heart) and rehab*" as theme，studies regarding cardiac rehabilitation included in the Web of Science Core Collection from 2000 to 2020 were searched in August 1，2020. VOSviewer 1.6.14 and CiteSpace 5.6.R3 were used to perform visualization analyses of the trend of publication，countries of publication，author institutions，and research hotspots of the eligible studies. Results　A total of 9 793 articles were included. The yearly number of publications was on the rise overall. The author institutions in developed countries have a long history of cardiac rehabilitation research and a great influence on this field. The topics in these studies mainly focused on：the exploration of new forms of cardiac rehabilitation，forms of exercise interventions，integrated health management and psychological interventions for cardiac rehabilitation. Conclusion　Our analysis indicated that for exploring forms of cardiac rehabilitation suitable for Chinese cardiovascular disease patients，priority should be given to strengthening the idea of patient-centered rehabilitation，with enough consideration on current research hotspots，and the use of the emerging technologies and family- and community-related factors.
