[The diagnostic significance of creatine phosphokinase antibodies in the cardiac muscle in non-coronarogenic myocardial diseases].

Complement-binding antibodies to myocardium and cardiospecific enzyme creatine phosphokinase were determined in 25 patients with dilated cardiomyopathy, 29 patients with rheumatic myocarditis and in 21 patients with non-rheumatic myocarditis. The antibodies were shown to have diagnostic and differentiating significance in severe non-coronary heart disease associated with disordered systolic function of the heart.
