Research map of global trends, hotspots, and emerging topics in cardiovascular disease: A bibliometric analysis.
Article in Medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Cardiology and cardiovascular medicine (CCM) journals hold a critical role in advancing medical research. This study aims to analyze bibliometric trends across CCM journals categorized into quartiles (Q1-Q4) based on the Scimago Journal Rank, to identify research hotspots, productive contributors, and emerging topics within the field. A systematic search was conducted in the Scopus database to collect bibliometric data from CCM journals spanning Q1 to Q4 categories. Journals were filtered by subject area "Medicine" and subject category "Cardiology and Cardiovascular Medicine." Bibliometric data were extracted using Excel and analyzed with VOSviewer software. Co-occurrence analysis of author keywords and visualization of research trends were performed for each quartile. A total of 113,482 documents from 381 CCM journals were analyzed, with 50.5% originating from Q1 journals, 24.5% from Q2, 17.3% from Q3, and 7.7% from Q4. "Heart Failure" emerged as the most frequent and influential keyword across all categories. "Cardiovascular Disease" and "COVID-19" are also showing high citation impact. Co-occurrence analysis revealed distinct research clusters, with thematic maps highlighting key topics. Emerging topics included "COVID-19" in Q2 journals and "Endovascular Procedures" in Q4 journals, reflecting current advancements in CCM research. This bibliometric analysis highlights variations in research focus and productivity across CCM journal quartiles. "Heart Failure" remains the primary research focus, while emerging topics like "COVID-19" and "Endovascular Procedures" demonstrate the field's evolving priorities. "Heart Failure" emerged as the most frequent and influential keyword across all categories. "Cardiovascular Disease" and "COVID-19" also show high citation impact.
