Abstract：Objective To conduct a visual analysis of relevant Chinese and English literature on cardiopulmonary function in the field of heart failure,and explore its research hotspots and trends.Methods Retrieve relevant literature published in China National Knowledge Infrastructure(CNKI)and Web of Science Core Database(WoSCC)from 2000 to 2023,and use VOSviewer and CiteSpace to visualize the annual publication volume,authors,journals,and keywords.Results In recent years,the overall number of publications related to cardiovascular and pulmonary function in patients with heart failure has been on the rise.The authors with the highest publication volume in CNKI are Sun Xingguo,Zhang Zhenying,Liu Yanling,etc.The authors with the highest publication volume in WoSCC are Agostoni Piergiuseppe,Salviani Elisabetta,Arena Ross,etc.The Chinese and English journals with the highest number of published articles are the Integrated Traditional Chinese and Western Medicine Cardiovascular Disease Electronic Journal and the International Journal of Cardiology.Keyword analysis shows that exercise tolerance,cardiopulmonary exercise testing,cardiac rehabilitation,and quality of life are research hotspots in this field.Conclusion The relevant research on cardiopulmonary function in patients with heart failure is currently in the high fever period.Cardiopulmonary function plays an important role in reducing mortality,improving prognosis,and enhancing quality of life in patients with heart failure.Cardiopulmonary exercise testing is the main method for quantifying cardiopulmonary function,and cardiac rehabilitation,especially exercise training,is an important means of improving cardiopulmonary function in patients with heart failure.
