Purpose: Cardiovascular and cerebrovascular diseases related to atherosclerosis represent a leading global health burden, contributing substantially to morbidity, disability, and premature mortality. The Ankle-Brachial Index (ABI) has emerged as a valuable non-invasive tool for screening peripheral artery disease and assessing the burden of systemic atherosclerosis. This bibliometric analysis aims to evaluate the research landscape, key contributors, and evolving trends in ABI and atherosclerosis studies.
Patients and Methods: A bibliometric analysis was conducted using data from the Web of Science Core Collection from 1989 to 2024. The data were analyzed using the R package “bibliometrix”, CiteSpace, and VOSviewer to identify research outputs, influential institutions, journals, authors, and keywords.
Results: This study included a total of 1896 eligible publications. The number of publications on ABI and atherosclerosis has steadily increased, peaking in 2021. The United States led in research output (n = 448) and citation impact (n = 29,980), followed by China and Japan. University of California System contributed the most publications, while Circulation and Atherosclerosis were the most influential journals. Criqui Michael H. emerged as the most cited author, with 5848 citations. Keyword analyses showed that the terms “cardiovascular disease”, “mortality”, “risk factors”, and “prevalence” terms had a high co-occurrence rate, while burst analyses showed that key terms such as “disease”, “epidemiology” and “events” were prominent in recent studies.
Conclusion: This bibliometric analysis offers a comprehensive perspective on the role of the ABI in the field of atherosclerosis research, and it offers crucial support for guiding future research directions.
