Bibliometric analysis of postoperative atrial fibrillation following coronary artery bypass grafting surgery

Background: Postoperative atrial fibrillation (POAF) is a common and serious complication following cardiac surgery, particularly after coronary artery bypass grafting. Despite extensive research into its pathophysiology and management, the incidence of POAF remains high, reflecting the complexity of its underlying mechanisms. Methods: This study provides a comprehensive bibliometric analysis of the literature on POAF following coronary artery bypass grafting from 1999 to 2023, utilizing tools such as VOSviewer, Bibliometrix, and CiteSpace. Results: We analyzed 1457 publications, identifying trends in publications, citation patterns, and collaborative networks. Key contributors, including influential authors, institutions, and countries, were mapped, and the thematic evolution of research was explored. Our findings highlight the prominent role of the United States in POAF research, the impact of key journals, and the evolving focus towards understanding inflammation, autonomic modulation, and epicardial adipose tissue in POAF development. Conclusion: This analysis underscores the need for further research to develop personalized prevention and management strategies, ultimately aiming to reduce the burden of POAF and improve patient outcomes.
