Overview
Myocarditis may be classified according to pathologic findings into 4 subtypes: fulminant myocarditis, acute myocarditis, chronic active myocarditis, and chronic persistent myocarditis.
Classification
Myocarditis may be classified according to pathologic findings into 4 subtypes:[1]
- Fulminant myocarditis: Fulminant myocarditis occurs following a viral prodrome. Fulminant myocarditis presents as acute severe cardiovascular compromise with ventricular dysfunction.[2] On endomyocardial biopsy, there are multiple foci of inflammation.
- Acute myocarditis: Acute myocarditis presents with a less distinct onset of the illness. When the patient does present, there is already a decline in left ventricular dysfunction. Acute myocarditis may progress to dilated cardiomyopathy.
- Chronic active myocarditis: Chronic active myocarditis has a less distinct onset of the illness. There are clinical and histologic relapses and the development of ventricular dysfunction. Histologically, chronic inflammatory changes with mild to moderate fibrosis may be present.
- Chronic persistent myocarditis: Chronic persistent myocarditis has a less distinct onset of the illness. Histologically it is characterized by persistent infiltration and myocyte necrosis. Despite the presence of symptoms, ventricular dysfunction is absent.
