Knowledge mapping of SGLT2-inhibitors and cardiovascular outcomes: A bibliometric analysis

Introduction

Initially developed for the treatment of type 2 diabetes mellitus (T2DM), SGLT2 inhibitors have increasingly been recognized for their substantial cardiovascular, renal, and metabolic benefits. This study undertakes a systematic bibliometric analysis to delineate research trends, quantify advancements, and identify influential studies on SGLT2 inhibitors and cardiovascular outcomes.

Methods

A comprehensive literature search was performed using the Scopus database, resulting in 10,211 documents up to the search date. Both original research articles and reviews (narrative and systematic) were included. Quantitative metrics such as publication count, citation analysis, and authorship were employed. Network visualization tools (e.g., VOSviewer) and bibliometric software (R Studio with bibliometrix packages) were used to analyze collaboration networks, keyword co-occurrence, and thematic clustering.

Results

The analysis revealed a significant upward trend in publication volume, with a notable peak in recent years, indicating a heightened interest in the topic among scientists. The United States and selected European institutions emerged as major contributors, with prominent authors and funding sources influencing the research output. Thematic analysis highlighted a focus on cardiovascular diseases, heart failure, renal outcomes, and mechanistic studies of SGLT2 inhibitor action. Notably, landmark randomized controlled trials have reported significant reductions in cardiovascular mortality, heart failure hospitalizations, and progression of kidney disease.

Conclusion

This study underscores the transformative impact of SGLT2 inhibitors on cardiovascular therapy. The analytical framework highlights the expansion of the field, and the integration of translational research.
