Myocarditis is a disease characterized by localized or diffuse inflammatory lesions in the myocardium. According to the established Dallas standard, histological evidence of myocardial infiltration is myocardial inflammatory cell infiltration, accompanied by degeneration and necrosis of adjacent myocardial cells. In 1991, Lieberman classified myocarditis into fulminant myocarditis, acute myocarditis, chronic active myocarditis and chronic protracted myocarditis according to the histological changes and clinical manifestations of myocardial biopsy.





　　According to BORSAM Biomedical,Clinical manifestations of myocarditis vary from asymptomatic to severe arrhythmia, acute cardiac insufficiency, cardiogenic shock and even death. Endocardial myocardial biopsy is the "gold standard" for the diagnosis of myocarditis. How is myocarditis treated? The treatment of myocarditis is mainly symptomatic auxiliary support treatment, mainly for active treatment of shock, heart failure and arrhythmia and other comprehensive treatment, especially the treatment of patients with fulminant myocarditis.
