To differentiate viral myocarditis from immune-mediated myocarditis in absence of the detected viral pathogen within EMB, several cardiac autoantibodies (e.g., anti-myosin, anti-fibrillary, anti-intercalated disk antibodies) have been described as possible serum markers for an immune-mediated process [4,23,31,32,33]. Here, MYH14 is linked to viral myocarditis.
