Myocardial infarction (MI) leads to cardiomyocyte death and accumulation of myofibroblasts (MFs) at the site of injury, which produce large amounts of extracellular matrix (ECM), generating a scar. Initially, cardiac fibrosis protects from ventricular wall rupture, but subsequent myocardial remodelling causes heart failure, representing a leading cause of death in Europe. While MFs play a central ...
