Abstract

Artificial intelligence (AI) has increasingly become a central component of healthcare research, yet a systematic understanding of its scholarly evolution remains limited. This study presents a comprehensive bibliometric analysis of 594 peer-reviewed publications indexed in Scopus between 2012 and April 2024, retrieved using a focused title-based search strategy. Using VOSviewer, we examine publication and citation trends, leading contributing countries and institutions, and thematic structures through keyword co-occurrence networks. Results reveal a marked acceleration in research output after 2018, with the United States, China, and the United Kingdom emerging as dominant contributors and central hubs in international collaboration networks. Keyword analysis indicates a strong methodological emphasis on machine learning, deep learning, and medical imaging, while comparatively limited attention is given to ethical, implementation, and equity-related themes. These findings highlight both the rapid growth and the thematic concentration of AI-in-healthcare research, underscoring the need for future studies to address translational and governance challenges alongside technical innovation.

A Bibliometric Analysis of Artificial Intelligence and Machine Learning Trends in Chronic Disease Management

Chronic diseases represent one of the most critical fields in healthcare systems, driving the majority of global deaths and healthcare costs. Artificial Intelligence (AI), Machine Learning (ML), and Deep Learning (DL) have increasingly shown their potential in disease diagnosis, prediction and management. In this study, we conducted a bibliometric analysis of the scientific literature on AI and ML applications in chronic disease. We applied a structured multi-criteria selection process in different steps to retain 566 publications for analysis. Publication trends, geographic distribution, journals, and keyword cooccurrence patterns were examined using multiple tools to analyse the retrieved documents. Results show an acceleration in research growth and the application of numerous AI approaches in various fields of chronic disease. However, we found a concentration of study and activity around some diseases and countries. These findings provide a consolidated overview of current research dynamics and establish a foundation for future investigations and foster more balanced international collaboration in chronic disease management.

Trends and hotspots in artificial intelligence applications for atherosclerosis research: A bibliometric analysis

Background Atherosclerosis (AS) is a complex systemic, immune-inflammatory vascular disease, and there is an urgent need to innovate its diagnostic and therapeutic strategies. The rapid advancement of artificial intelligence (AI) technology has opened up new avenues for the early diagnosis, risk prediction, and precision treatment of AS. However, a systematic quantitative analysis of global knowledge and collaboration in this field is still lacking. Methods This study conducted a systematic search of the Web of Science Core Collection (WoSCC), Scopus, and PubMed databases for literature on the application of AI in AS research published between 2000 and 2025. Advanced bibliometric tools, such as CiteSpace, VOSviewer, and R-Bibliometrix, were employed to conduct multidimensional visual analyses of publication trends, transnational collaboration networks, knowledge flows in core journals, and the emergence of keywords. Results A total of 258 core publications were ultimately included, involving 1,900 authors, 44 countries/regions, and 1,152 research institutions. The spatio-temporal distribution revealed that the volume of publications in this field has grown significantly, with rapid growth beginning after 2021. Globally, a China-U.S. dual-center pattern has emerged: China leads in terms of output scale and growth rate, while the United States holds higher citation accumulation in terms of total citations and average citations per paper. However, raw citation counts and average citations per paper are influenced by publication year, document type, and denominator size; these cross-country differences should therefore be interpreted with caution, and future studies using normalized indicators are warranted. The evolution of research hotspots has undergone a distinct three-stage transition: from early basic algorithm development (2000–2014), through multimodal image intelligent analysis (2015–2020), to the current phase of clinical multicenter validation and in-depth mechanism decoding (2021–2025). Journal overlay analysis further confirms that clinical medicine is increasingly intersecting with basic life sciences, driving bidirectional knowledge transfer. Conclusions This study systematically maps the global research landscape of AI in the field of AS, revealing its evolutionary path from methodological exploration to clinical translation. Future research should break down data barriers, advance multinational, multiethnic, and multicenter cohort validation, and focus on the development of interpretable AI models. The observed trends in the bibliometric data suggest that the integration of AI technology with systems biology and a holistic medical approach may play an increasingly important role in personalized, precision interventions for AS.
