BACKGROUND: Air pollution is a major global health concern and a well-established risk factor for cardiovascular disease (CVD). While earlier bibliometric efforts provided useful insights into early research patterns using MeSH term clustering, they were limited in scope and time frame. A more comprehensive synthesis is needed to reflect the expanding and evolving nature of this field. OBJECTIVES: To map the global research landscape on air pollution and cardiovascular health, identifying trends, key contributors, and thematic developments through bibliometric analysis. METHODS: A bibliometric study was conducted using the Scopus database, including 6,663 publications from 1963 to 2025. Data was analyzed using Bibliometrix (R), VOSviewer, and CiteSpace. Analytical approaches included performance analysis, coauthorship networks, co-citation mapping, keyword co-occurrence, and thematic evolution analysis. RESULTS: , cardiovascular outcomes (e.g. hypertension, myocardial infarction), and biological mechanisms (e.g. inflammation, oxidative stress). Thematic evolution reflected a shift from acute exposure studies to broader interdisciplinary concerns like climate change, urban planning, and environmental justice. Collaboration networks highlighted strong interregional partnerships, particularly among North American, European, and Asian researchers. However, contributions from low-income regions remain limited. CONCLUSION: This study provides an expanded and updated overview of research linking air pollution to cardiovascular health. By building on earlier bibliometric work, it highlights emerging interdisciplinary priorities and underscores the need for equitable, evidence-based policy responses to environmental health risks.
