title: Viral myocarditis.
abstract: Although most cases of viral myocarditis are subclinical, some patients develop overt symptomatic disease. These patients may present with findings that range from benign myopericarditis to frank heart failure. Furthermore, a growing body of evidence links viral myocarditis with idiopathic dilated cardiomyopathy, sudden death, and chronic arrythmias. The pathogenesis of the disease is currently incompletely understood in humans but is being investigated in animal models. A multifactorial process involving direct viral damage, autoimmunity, and possibly vascular damage is emerging. Breakthroughs in rapid diagnosis, such as the use of DNA probes, are occurring and may soon provide the opportunity for early intervention. Although there is currently no widely accepted standard of treatment, promising new therapeutic modalities are under investigation. These include the use of general immunosuppressive agents, T cell monoclonal antibody, interferon, specific immunization, and synthetic antiviral agents.
