Trends in Acupuncture Therapy in Cardiovascular Disease: A Bibliometric Analysis.

ABSTRACT

Purpose: Acupuncture has been used for almost half a century to treat and prevent cardiovascular (CV) problems. However, most of its effects are poorly understood, and there are few studies based on bibliometric analysis of the general trends in acupuncture therapy in cardiovascular disorders (CVD). Thus, we aimed to show the present state and trends in this sector during the last few years. Methods: Articles were obtained from the Web of Science Core Collection (WOSCC) from its inception to May 30, 2021. The acquired information from the articles was analyzed by The Online Bibliometric Analysis Platform website (https//bibliometric.com), Citespace and VOSviewer in respective form in order to assess and forecast the hottest areas and trends in this field. Results: The final analysis included a total of 384 articles and reviews. Over the years, the number of publications has gradually increased. The United States and University of California Irvine were the country and institution that contributed the most to the field. John C Longhurst was the most productive author; Li P the most cited author. Co-occurrence analysis revealed 5 branches (including acupuncture, blood pressure, electroacupuncture, stimulation, cardiovascular responses) and 12 clusters. Recent keyword bursts included "reflex," "arcuate nucleus," "electroacupuncture," "cardiovascular disease" and "hypertension." Conclusion: Yearly publications continue to increase every decade, indicating a bright future in this scientific field. Acupuncture's function in CVD is a future study priority.
