Clinical Features and Therapeutic Outcome of Fulminant Myocarditis / 日本農村医学会雑誌

ABSTRACT

Four patients with fulminant myocarditis (two males and two females, age 21-67 years old) were examined during 1995-2001. Fulminant myocarditis was diagnosed based on clinical features, abnormal electrocardiographic and echocardiographic findings, and increased serum enzyme levels. In three of four cases, the diagnoses were confirmed histologically in autopsy. All four patients had flu-like symptoms and fever at the start. One patient died suddenly next day. Other three patients went into cardiogenic shock five and seven days after the onset of symptoms and hospitalized, and treated with temporary pacing, steroid pulse therapy, catecholamine (in all three patients) and percutaneous cardiopulmonary support PCPS (in one patient), but they died within ten days. Electrocardigrams showed ventricular escape rhythm, ST elevation associated with Q wave, and low voltage of the QRS complex. Markedly increased serum enzyme levels, severe metabolic acidosis and disseminated intravascular coagulation were thought to be indicative of poor prognosis. Early recognition of cardiac involvement and using of PCPS without hesitation in an acute phase could improve the outcome of fulminant myocarditis.
