    BackgroundIn recent years, many studies have addressed cardiac aging and related diseases. This study aims to understand the research trend of cardiac aging and find new hot issues.MethodsWe searched the web of science core collection database for articles published between 2003 and 2022 on the topic of "cardiac aging." Complete information including keywords, publication year, journal title, country, organization, and author were extracted for analysis. The VOS viewer software was used to generate network maps of keywords, countries, institutions, and author relationships for visual network analysis.ResultsA total of 1002 papers were analyzed in the study. Overall, the number of annual publications on cardiac aging has increased since 2009, and new hot topics are emerging. The top 3 countries with the most publications were the United States (471 articles), China (209 articles) and Italy (101 articles). The University of Washington published the most papers (35 articles). The cluster analysis with author as the keyword found that the connections among different scholars are scattered and clustered in a small range. Network analysis based on keyword co-occurrence and year of publication identified relevant features and trends in cardiac aging research. According to the results of cluster analysis, all the articles are divided into 4 topics: "mechanisms of cardiac aging", "prevention and treatment of cardiac aging", "characteristics of cardiac aging", and "others." In recent years, the mechanism and treatment of cardiac aging have attracted the most attention. In both studies, animal models are used more often than in human populations. Mitochondrial dysfunction, autophagy and mitochondrial autophagy are hotspots in current research.ConclusionIn this study, bibliometric analysis was used to analyze the research trend of cardiac aging in the past 20 years. The mechanism and treatment of cardiac aging are the most concerned contents. Mitochondrial dysfunction, autophagy and mitophagy are the focus of future research on cardiac aging.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
