Myocarditis classification



Myocarditis is inflammation of myocardium. It is usually viral and Cocksackie B is the commonest virus isolated. Myocarditis can be classified into the following 3 types based on pathologic findings per the Dallas Criteria (1987):

Active myocarditis - Characterized by abundant inflammatory cells and myocardial necrosis (subclassified into ongoing, resolving, or resolved myocarditis.)

Borderline myocarditis - Characterized by an inflammatory response that is too sparse for this type to be labeled as active myocarditis; degeneration of myocytes not demonstrated with light microscopy (subclassified into ongoing, resolving, or resolved myocarditis.)

    Is this really USMLE stuff? Do they really ask all this?
