基于CiteSpace的肺动脉高压研究可视化分析OA

Objective To analyze the research frontiers and hot spots in the field of pulmonary hyper-tension(PH)in the past 10 years,and to provide a certain reference for the future research in this field.Meth-ods The related literatures in the field of PH in the core collection of the Web of science database from 2012 to 2021 were retrieved.The CiteSpace software was used to perform the co-occurrence analysis of authors,in-stitutions and countries,and the cluster analysis and burst analysis were conducted on the keywords.Results A total of 12 774 related articles were included.The analysis results showed that the researches on PH in recent years maintained an upward trend,the largest number of published articles in this field was in the United States.Among the research institutions,the University of California-San Diego has high academic in-fluence;In this field,there were 130 core authors who published more than 10 articles.The research hotspots in the field of PH mainly focused on the pathogenesis,early diagnosis and prognosis,targeted drugs,persistent PH in neonates and pulmonary fibrosis-related PH.Conclusion In the last 10 years,the research hotspots in the field of PH have been continuously updated.The value of new targeted drugs and biomarkers in the diag-nosis and prognosis is the focused research direction in the future.
