It is uncommonly observed in infections such as parvovirus B19 or human herpesvirus 6 which according to a distinct pathophysiology do not directly affect contractile cells of the myocardium.Parvovirus B19 and human herpes virus 6 respond less well upon IFN-β treatment with respect to virus clearance and haemodynamic changes, although affected patients too improve clinically despite incomplete virus clearance following reduction of virus load and/or improvement of endothelial dysfunction.Information taken from uncontrolled cohorts of treated virus-positive patients may be, however, of limited value for general treatment recommendations for a number of reasons.
