[Importance of a comprehensive evaluation of the size of cardiac muscle necrosis for the prognosis and treatment of acute myocardial infarct patients].

The authors present comparative characteristics of different methods of assessing the size of myocardial infarction. They included among others radioimmunoassay of myoglobin and the activity of MB-CPK in the blood serum, ECG charting with the calculation of the ST-coefficient and 99mTc-pyrophosphate scanning of the myocardium. The most informative methods were determination of the serum content of myoglobin and of its hourly increment, monitoring of the total rise of the ST segment and ST coefficient on the cartogram and the measurement of the area of accumulation of radiopharmacologic preparations during myocardial scanning.
