[The intravital determination of the mass of necrotized myocardium by the myoglobin concentration in the blood serum in large-focus myocardial infarct].

The investigations indicate high informative value for determination of blood serum myoglobin content for assessment of the degree of myocardial lesion. Determination of myoglobin may be used for indirect evaluation of the mass of myocardium infarction during life. The proposed method of quantitative determination of myocardial lesion in acute macrofocal infarction allows to prognosticate the mass of necrotized myocardium.
