Integrative Transcriptomic-Histological Analysis in Dilated Cardiomyopathy Unveils FGFR1 Inhibition as Anti-Cardiac Fibrotic and Cardioprotective Therapy.

ABSTRACT: Cardiac fibrosis drives dysfunction in dilated cardiomyopathy (DCM); yet, effective therapies are limited. This study identifies FGFR1 as a critical target in cardiac fibrosis using transcriptomic and histological analyses of 58 human DCM biopsies. FGFR1 expression correlated with fibrosis severity, and inhibition by AZD4547 reduced fibrosis and improved cardiac function in organoid and murine models. These findings validate FGFR1 inhibition as a promising therapeutic strategy for mitigating fibrosis and improving outcomes in heart failure associated with DCM.
