Clinical Assessment of New Treatment Regimen for Adult Fulminant Myocarditis

Inclusion Criteria: * 16 years of age or older; * Diagnosed as fulminant myocarditis: * Evidence of myocarditis on biopsy or increased biomarkers of myocardial injury (TNI and CK-MB and BNP or NT-pro-BNP); * Acute onset of symptoms of cardiac dysfunction: dyspnea, palpation, chest pain, and/or syncope; * Image for cardiac injury: marked diffused reduction in left ventricle wall movement, with dramatically decreased left ventricle ejection fraction (LVEF) \< 45%; * Cardiogenic shock, e.g., systolic blood pressure ≤90 mmHg or mean arterial pressure \< 70mm Hg or a systolic blood pressure decrease \> 40 mm Hg, which is associated with the signs of hypofusion: cyanosis, cold extremities, oliguria, and/or changes in mental status. Exclusion Criteria: * Also considering acute coronary syndrome but unable to perform coronary angiography to distinguish acute coronary syndrome from fulminant myocarditis; * Myocardial injury caused by sepsis, chemotherapeutical agents, or poisons; * Unstable hemodynamics or shock caused by hypovolemia.
