The miRNA-related research in the heart disease (HD) field has received close attention in the past two decades. However, there is a lack of studies that comprehensively and objectively analyze the current situation of miRNA application in the HD field using the bibliometrics method.<h4>Objective</h4>To comprehensively analyze the global scientific outputs of miRNAs in HD research from 2004 to 2023.<h4>Methods</h4>All the articles and reviews of miRNA-related research in the HD field were retrieved using the Web of Science core collection (WOSCC) title search, and bibliometric analysis was performed in Microsoft Excel 2019, CiteSpace, VOSviewer, and BibliomeFrontiers in cardiovascular medicine1465646https://www.ebi.ac.uk/biostudies/studies/S-EPMC11965657biostudies-literatureBibliometric and visual analysis of miRNAs in heart diseases from 2004 to 2023.PMC11965657Duan JZhang WYin QMa YJin YLou JfalseBibliometric and visual analysis of miRNAs in heart diseases from 2004 to 2023.<h4>Background</h4>MicroRNAs (miRNAs) add a new dimension to HD forecast, diagnosis, and therapy based on the potential applications.
