Bibliometric and visual analysis of hypoxic pulmonary hypertension from 2013 to 2022

Hypoxic pulmonary hypertension (HPH) is caused by chronic persistent hypoxia, which leads to the continuous increase of pulmonary artery pressure and pulmonary vascular resistance. In recent years, there has been a substantial increase in research on HPH. To study the trends of HPH research over the last decade, we used WOSCC to search for relevant research on this topic, and dealt with the relevant information using VOSviewer, CiteSpace, and R-tool. Our results show that the number of publications on HPH has generally increased in the last decade, albeit not significantly, while the average number of citations has been declining year by year. Researchers from the USA top the list with 5498 publications, who widely cooperate with researchers from other countries, followed by those from China. Kurt R. Stenmark has an authoritative position in this field, ranking first with 635 citations. American Journal of Physiology Lung Cellular and Molecular Physiology and Pulmonary Circulation have published 151 articles on HPH in the last 10 years, but the former has higher impact factor and article quality. Circulation proved its leadership in this field with 8812 citations. Our findings reveal the trends in HPH research and should provide researchers with plenty of useful information.
