Objective To analyse the knowledge graph of papers in the field of cardiac rehabilitation at home and abroad in recent 20 years to explore the development process, research hotspot and cutting-edge trend of this field.
Methods By searching and screening the relevant literature on cardiac rehabilitation published in CNKI and Web of Science databases from January 2000 to August 2021, the authors, institutions and countries of the included literature were analysed by CiteSpace software and the graphs were generated by keyword co-occurrence, clustering and emergence for visual analysis.
Results Through subject word search, a total of 1 238 Chinese documents and 10 098 English documents were obtained. A total of 197 and 233 Chinese and English documents were excluded on the basis of the exclusion criteria. Finally, 1 041 and 9 865 Chinese and English documents were included in the analysis. Fuwai Hospital, Peking University People's Hospital, Beijing Anzhen Hospital and other institutions had a large number of Chinese papers. English papers were represented by the United States, with a large number of documents issued by European and American developed countries. Most research institutions are hospitals or schools, lacking leading participation at the national or government level and the scientific research force was single. For international cooperation, the European and American countries represented by the United States cooperate closely but the cooperation showed the characteristics of localisation. The contents mainly focused on six aspects ： medical evaluation of cardiac rehabilitation, evaluation of exercise training, compre- hensive health management, social psychological evaluation, evaluation of results and new exploration of cardiac rehabilitation model.
Conclusion Knowledge graph analysis intuitively shows the current situation of the development of cardiac rehabilitation at home and abroad. Compared with the development of cardiac rehabilitation abroad, priority should speed up the development process of cardiac rehabilitation discipline, improve the cardiac rehabilitation model, pay equal attention to traditional Chinese and Western medicine and form a cardiac rehabilitation scheme with Chinese characteristics.
摘要：目的 本研究对近20年国内外心脏康复领域研究文献进行知识图谱分析, 以探索本领域发展的进程、研 究热点和前沿趋势。 方法通过对2000年1月一2021年8月发表在中国知网和Web of Science数据库的心脏康 复相关文献进行检索并筛选, 利用CiteSpace软件对纳人的文献进行作者、机构国家共现分析, 关键词共现、聚类 和突现生成图谱, 进行可视化分析。 结果通过主题词检索, 共获得中文文献1 238篇, 英文文献10 098篇, 通过 排除标准, 剔除中英文文献各197篇和233篇, 最终纳人分析的中英文文献分别为1 041篇和9 865篇。中文文 献以阜外医院、北京大学人民医院和北京安贞医院等机构发文量较多, 英文文献是以美国为代表的欧美发达国家 发文数量多。研究机构多为医院或学校, 缺乏国家或政府层面的牵头参与, 科研力量单一。对于国际间的合作, 与以美国为代表的欧美国家合作较密切, 但合作呈现局域性特点。研究内容主要集中在心脏康复医疗评估、运动 训练评估、健康综合管理、社会心理评估、对结果的评估和心脏康复模式新探索6个方面。 结论通过知识图谱 分析直观地展示了国内外心脏康复发展的现状, 相对于国外心脏康复的发展, 我国应加快心脏康复学科发展进 程, 改善心脏康复模式, 中西医并重, 形成符合中国特色的心脏康复方案。
