Evidence and perspectives on miRNA, circRNA, and lncRNA in myocardial ischemia-reperfusion injury: a bibliometric study.

Objective: miRNA, circRNA, and lncRNA play crucial roles in the pathogenesis and progression of myocardial ischemia-reperfusion injury (MI/RI). This study aims to provide valuable insights into miRNA, circRNA, lncRNA, and MI/RI from a bibliometric standpoint, with the goal of fostering further advancements in this area.

Methods: The relevant literature in the field of miRNA, circRNA, lncRNA, and MI/RI was retrieved from the Science Citation Index Expanded (SCI-E) database within Web of Science. The "Analyze Results" and "Citation Report" functions in WOS were utilized to compile the annual publication and citation counts in this field. Microsoft Office Excel 2019 was used to organize and visualize the data. Furthermore, bibliometric and visualization analyses of countries/regions, institutions, authors, keywords, and references were conducted using the bibliometric visualization software CiteSpace.

Results: A total of 858 publications were included for further analysis in this field. The literature was published across 297 journals, with Molecular Medicine Reports contributing the highest number of publications. Researchers from 45 countries participated in studies within this field, with those from China contributing the most publications. The research hotspots in this field primarily focus on three areas: the role of miRNA, circRNA, and lncRNA in the pathogenesis of MI/RI, their potential as therapeutic targets, and their role as biomarkers. Among these, circular RNA, therapy target, inflammatory response, and cardiomyocyte ferroptosis are likely to emerge as emerging trends in this field.

Conclusion: The overall development of research in this field is on the rise. The compilation of research hotspots and emerging trends in this area may provide researchers with more references and assistance in selecting research directions, ultimately benefiting MI/RI patients.
