Abstract
Clinically, viral myocarditis may appear in a wide variety of forms, ranging from a total lack of clinical manifestations to sudden, unexpected death. Myocarditis may be subacute or even chronic, leading to progressive myocardial failure and death [1, 2]. We have developed animal models for viral myocarditis using encephalomyocarditis (EMC) virus in which congestive heart failure developed in a range of the acute to subacute stages [5], and dilatation and hypertrophy as seen in dilated cardiomyopathy developed in the chronic stage [6]. Histologically, myocardial necrosis became apparent on day 7, cellular infiltration was most marked on day 14, and thereafter, inflammatory reaction decreased, and fibrosis appeared; calcification persisted to day 28. Marked myocardial fibrosis and hypertrophy of myocardial cells became evident on day 90. We have investigated the natural history and pathogenesis of viral myocarditis and assessed diagnostic methods and therapeutic and preventive interventions in these models [7–20, 23, 26–28, 30, 31, 34]. This review discusses our recent therapeutic trials of viral myocarditis.
