Abstract
BACKGROUND: Heart transplantation (HT) remains the most effective long-term treatment for end-stage heart failure (HF). As the field continues to evolve, bibliometric analysis offers insights into historical developments and emerging trends. METHODS: A comprehensive bibliometric analysis was conducted using the Web of Science Core Collection (WOSCC), covering HT-related publications from 1975 to 2023. Extracted data included publication year, type, citation metrics, contributing countries and institutions, journals, authors, keywords, and references. RESULTS: A total of 8414 publications were retrieved, comprising 6356 original articles and 1018 reviews. Global research output steadily increased over the study period. The United States led in publication volume and citations, with significant contributions from institutions in Europe and Asia. Core journals and prolific authors were identified, highlighting the academic landscape. Research hotspots included clinical immunosuppressive therapy, ventricular assist device (VAD) technology, and donor allocation strategies. CONCLUSIONS: The field of HT for HF has experienced substantial growth, with continued focus on immunosuppression, mechanical circulatory support, and organ allocation. These areas are likely to remain central in future research, reflecting ongoing efforts to improve patient outcomes and expand transplant accessibility.
