Bibliometric Analysis on the Progress of Chronic Heart Failure

Abstract

Chronic heart failure (CHF) is the terminal stage of a variety of heart diseases with higher morbidity and mortality. Although CHF has been studied for decades, the comprehensive analysis by bibliometrics has not been done. So, we analyzed the scientific outputs of global chronic heart failureresearches, explored the current research status and hotpots from 2009 to 2019. Web of Science Core Collection was the data source, and the data was retrieved on June 25, 2020, according to the set search strategy. Bibliometrics tools- CiteSpace V (Drexel university, Chaomei Chen) and VOS viewer (Leiden University, van Eck NJ)-were used for analyzing published literature and exploring research hotspots and frontier directions. A total of 21,484 articles were included, and the rate of published articles increased from 2009 to 2019 annually. United States of America was the leading country, Duke University was the leading institution, and Stefan D Anker was the most productive researcher in this field. The analysis of keywords showed that mortality, risk, outcomes, association, and dysfunction were the main hotpots and frontier directions of CHF. Bibliometric analysis of the outputs on CHF shows an overall view about the current status of the research on CHF. Clinical treatment and the associations among organs in the patients with CHF are the major research frontiers. However, further research and collaboration are still required worldwide. Our findings can help researchers grasp the research status of CHF and determine new directions for future researches as soon as possible.
