Cardiomiopatia infiammatoria: posizione del Gruppo di lavoro della Società Italiana di Cardiologia sulle cardiomiopatie e le malattie pericardiali in collaborazione con il Gruppo di lavoro della Società Italiana di Cardiologia sulla risonanza magnetica cardiaca.

Inflammatory cardiomyopathy (iCMP) usually represents the chronic, hypokinetic phenotype within the myocarditis spectrum, characterized by persistent myocardial inflammation, systolic ventricular dysfunction, and adverse remodelling. It frequently evolves from prior acute or subacute myocarditis and is associated with significantly worse outcomes, including progression to dilated cardiomyopathy, heart failure, and arrhythmias. The condition arises from heterogeneous causes-infectious, autoimmune, or idiopathic-and may be influenced by genetic susceptibility, supporting a two-hit model in which environmental triggers interact with pathogenic variants. Diagnosis requires a multimodal approach.
