Abstract BACKGROUND Novel collagen-derived circulating peptides, such as endotrophin, have been proposed as biomarkers of myocardial fibrosis. OBJECTIVES We aimed to determine the effect of pirfenidone, an antifibrotic agent, on circulating levels of these peptides, and their association with cardiovascular magnetic resonance extracellular volume (ECV). METHODS In the PIROUETTE (Pirfenidone in Patients with Heart Failure […]
