title: [Influenza myocarditis and pericarditis].
abstract: The true incidence of influenza myocarditis in the general population is unknown, because of the variable clinical presentation and the absence of a established noninvasive diagnostic test that can confirm the diagnosis. Influenza is, however, one of the frequently implicated viruses caused myocarditis as well as Coxsackie B, adenovirus, echovirus and cytomegalovirus. The clinical manifestations of viral myocarditis vary greatly from asymptomatic electrocardiographic changes to fulminant heart failure with fatal arrhythmias. We should recognize that subtle cardiac symptoms and signs in many subclinical cases may be overshadowed by systemic manifestations of the underlying influenza infection. Although specific therapy consisted of anti-viral agents, intravenous gamma-globulin treatment or mechanical ventricular supports may be available for influenza myocarditis, it has not been established that the myocarditic process itself will be favorably affected.
