A Bibliometric Analysis of Global Research Trends in Blood Pressure Variability

Abstract Background The term “blood pressure variability” refers to the degree of fluctuations in blood pressure over a specified period. Given the ongoing emergence of clinical concepts and innovative technologies, a bibliometric analysis was undertaken to reveal worldwide research patterns, focal areas, scientific frontiers, and output characteristics related to blood pressure variability between 2000 and 2022. Materials and Methods A bibliometric analysis was performed to assess the number of publications, keywords, journals, citations, affiliations, and countries. The Web of Science Core Collection was used to retrieve relevant literature and associated information from the period spanning 2000–2022. To provide a comprehensive visual analysis of the research trends and hotspots related to blood pressure variability, the visualization tools VOSviewer and CiteSpace were employed. Results A total of 3188 documents (including 2815 articles and 373 reviews) published from 2000 to 2022 were retrieved, indicating consistent growth in the volume of publications over the specified duration. JOURNAL OF HYPERTENSION is the leading journal on BPV. The United States was identified as the most significant contributor to this research area, whereas UDICE FRENCH RESEARCH UNIVERSITIES from France emerged as the leading institution actively engaging in relevant research. The scholarly contributions of Kario, Kazuomi, Su, Ding-Feng and other researchers were deemed notable. Powers. WJ's paper, published in 2018, received the highest global citation score. Keywords such as “hypertension”, “blood pressure”, “mortality” and “stroke” were found to be the most frequently recurring, and research on blood pressure variability encompasses both clinical and fundamental investigations. Conclusions The number of studies conducted in the field of blood pressure variability has consistently increased over time. This article presents a comprehensive overview of the foremost scholarly journals, nations, academic institutions, researchers, and extensively referenced articles on a global scale. Research in this domain has transitioned from investigating the underlying mechanisms associated with fluctuations in blood pressure to appraising the public health implications of blood pressure variability. Mounting recognition of the clinical significance of blood pressure variability has established robust groundwork for forthcoming advancements in clinical medicine and scientific inquiry.
