[Blood kinin system in acute myocardial infarct treated with thrombolytic preparations]. / Kininovaia sistema krovi u bol'nykh ostrym infartom miokarda pri lechenii tromboliticheskimi preparatami

ABSTRACT

The treatment of patients with acute myocardial infarction by thrombolytic agents affects several indices characterizing the pathological process. The effect of thrombolytic therapy was studied with reference to the activation of the blood kinin system. The data on a activating effect of myocardial infarction upon the state of the kinin sys tem were proved. When thrombolytic agents (streptoliase, streptase and fibrinolysin) and heparin are given, the kinin system is activated still further which clearly correlates with an elevated fibrinolytic activity of the blood. Under fibrinolytic therapy the most sensitive component of the kinin system proves to be kallikreinogen. The possible effect of the activation of the blood kinin system by thrombolytics upon the state of myocardial infarction patients is discussed.
