AbstractTo comprehensively review cardiorenal syndrome (CRS)-related research, this study analyzes its whole landscape and future trends from a bibliometric perspective. Using "cardiorenal syndrome" as the key word, a representative dataset of CRS was constructed in the Web of Science Core Collection (Science Citation Index Expanded) database up to November 2023. VOSviewer (version 1.6.18) and R-Studio (version 1.4) were used to visualize CRS-related author and national collaboration networks, hotspot distribution clustering and historical citation networks. The annual number of publications shows an upward trend, especially since 2009. The United States is the most active country and closely cooperates with European countries. Cardiorenal Medicine is the journal that publishes the most CRS-related research. Urology & Nephrology and Cardiovascular System & Cardiology are the most prominent areas of CRS literature output. The leaders in CRS-related research are Ronco C from Italy and Mccullough PA, from the United States. Combined with keyword co-occurrence, theme evolution, and strategic distribution analysis, it was found that centering on the mechanism of CRS (cardiovascular lesions, venous congestion, and fibrosis), prognosis (transplantation, dialysis, hospitalization, mortality) and cardiac function management (b-type natriuretic peptide, diastolic dysfunction, left ventricular hypertrophy) is a possible research direction for a long time to come. Although CRS has a relatively short history, it has received a lot of attention and is currently enjoying a high level of overall acceptance. In conclusion, this study explores the major research areas, frontiers and trends in CRS, which are important for future research.Copyright © 2024 the Author(s).
