Publication trends and research hotspots of the cardiorenal syndrome: A bibliometrics and visual analysis from 2003 to 2023.

INTRODUCTION:Cardiorenal syndrome encompasses a range of disorders involving both the heart and kidneys, wherein dysfunction in one organ may induce dysfunction in the other, either acutely or chronically. This study conducted a literature search on cardiorenal syndrome from January 1, 2003, to September 8, 2023. Meanwhile, a quantitative analysis of the developmental trajectory, research hotspots and evolutionary trends in the field of cardiorenal syndrome through bibliometric analysis and knowledge mapping. SUMMARY:The field of cardiorenal syndrome exhibits promising potential to grow and is emerging as a prominent research area. Future endeavours should prioritise a comprehensive understanding of the field and foster multi-centre co-operation among different countries and regions. KEY MESSAGES:The annual publication trend analysis revealed a consistent annual increase in cardiorenal syndrome literature over the last 20 years. The IL6, REN and INS genes were identified as the current research hotspots.
