The mode of transmission is unknown and in the majority of cases the viral agent is also unknown. About a third of patients with viral myocarditis get worse, a third stay the same and a third get better. There is no way to tell what group an individual is in except to wait and see. There is no treatment of viral myocarditis per se. The symptoms and the heart failure are treated with ACE inhibitors, diuretics, and digoxin.
Cardiac transplant is an option for some individuals.
