FIELD: medicine.
SUBSTANCE: method involves examining myocardium by examining myocardium biopsy material stained with silver nitrate. Stroma cell nuclei area is determined and cardiac hystiocyte manifesting protein synthesis function disorders are detected as micronuclei and ring-shaped nuclei. The stroma cell nuclei area being greater than 40 mcm2 and share of cardiac hystiocyte manifesting protein synthesis function disorders being not less than 30%, idiopathic restrictive cardiac myopathy is to be diagnosed.
EFFECT: high specificity and simplicity of the method.
