[Sympathetic-adrenal system in various complications of myocardial infarct]

The condition of the blood sympathetico-adrenal system was studied in 200 patients suffering from macrofocal myocardial infarction with various clinical courses. Considerable hyperadrenalia was determined when myocardial infarction was complicated by acute cardiac insufficiency, cardiogenic shock or acute disorders of rhythm. High noradrenalin ejection was noted in rupture of the myocardium. Determination of activity of the sympathetico-adrenal system is important in appriasal of the severity and prognosing of the disease and the choice of the tactics of rational therapy in myocardial infarction and its complications.
