title: [Antiviral therapy in viral heart disease].
abstract: Several investigations showed that in addition to genetic factors also virological and chronic inflammatory aspects are relevant pathogenic mechanisms for the development of dilated cardiomyopathy (DCM). Based on the etiopathogenic importance of viral persistence and chronic myocardial inflammation for disease progression, novel rational therapeutic strategies have been developed. The diagnosis of chronic myocardial inflammation and viral persistence has been a controversial issue for a long time due to diagnostic pitfalls. Detection of persistence of viral genomes with adequate sensitivity and specificity succeeded only by the establishment of sensitive molecular biological techniques such as in situ hybridization and nested polymerase chain reaction (nPCR). By the use of these molecular biological methods, further viruses have been detected in DCM patients in addition to the classic cardiotropic viruses (entero- and adenoviruses), particularly parvovirus B19, human herpes virus type 6 (HHV-6), and Epstein-Barr virus. Considering these different cardiotropic viruses, viral persistence can be proven in > 50% of the DCM patients, consistent with the diagnosis of viral heart disease. This differentiated diagnosis enables, in addition to symptomatic therapy of heart failure, novel rational therapeutic regimens (e. g., beta-interferon) in the setting of randomized trials such as the BICC Study (Betaferon In Patients with Chronic Viral Cardiomyopathy).
