title: [Size of myocardial necrosis and left ventricular insufficiency in acute myocardial infarct].
abstract: The dependence between the severity of cardiac insufficiency and the size of the necrotic lesion of the heart muscle, measured according to the area of 99m Tc-pyrophosphate cumulation and the rate of liberation of the isoenzyme MV creatine phosphokinase into the blood, was studied in 77 patients with myocardial infarction in the acute period of the disease. It was demonstrated that the severity of left ventricular insufficiency is directly dependent on the size of necrosis of the heart muscle. Not only the size of the necrotic focus but also the state of the contractility of the other parts of the myocardium is an important factor determining the origin and severity of cardiac insufficiency.
