Cell adhesion is essential for tissue integrity and the regulation of inflammation and fibrosis. This study aimed to identify key cell adhesion-related genes (CARGs) and explore their roles in HF.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>HF-related transcriptomic datasets (GSE1621, GSE5500, GSE36074, GSE18224, GSE308859, and GSE116250) were obtained from GEO. Differentially expressed genes were intersected with cell adhesion-related genes from MSigDB to identify CARGs. Functional enrichment and protein-protein interaction analyses were performed. A CARG-based CelladhesionScore was constructed to evaluate its discriminatory value and associated pathways. Key CARGs were identified using CytoHubba. Single-cell transcriptomic analysis was conducted to assess fibroblast states and gene dynamics. GSE36074 and a transverse aortic constriction (TAC) mouse model were used for validation by qPCR, Western blotting, and immunohistochemistry.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Forty-five differentially expressed CARGs were identified and were mainly enriched in cell adhesion, extracellular region, and ECM-receptor interaction pathways.
