FIELD: medicine, obstetrics, pediatrics. SUBSTANCE: it is necessary to test blood serum in the newborns, on 3d-4th d of their life the activity of MV-fraction of creatine phosphokinase MV- CPK and troponine-T level are studied and at MV-CPK increase ranged 0.054-0.072 mccat/l, troponine-T 0.1-0.2 ng/ml against those in healthy babies antenatally appeared myocardial ischemia is diagnosed, and at MV-CPK increase ranged 0.081-0.092 mccat/l, troponine-T 0.4-16.0 ng/ml a postnatal myocardial ischemia is concluded on. EFFECT: higher accuracy of differential diagnostics.
