[Status of the kallikrein-kinin system of the blood in young and middle-aged patients with ischemic heart disease].

Increase in BAEE-esterase and kallikrein activities, simultaneously with decrease in alpha 2-macroglobulin and prekallikrein activities were found in blood plasma of young and middle age patients with heart ischemic disease. The maximal alterations were observed in young patients as well as in patients, subjected to heart infarction less than a year before the examination. Maximal activity of kallikrein was accompanied by deterioration of fibrinolytic activity, by hypertriglyceridemia and by increase in adrenaline excretion. Dietetics normalized partially the state of kallikrein-kinin system, especially, in patients ration of which contained soybean products.
