[Possibilities of prevention and therapy of arteriosclerosis by influencing hemostatic functions].

Thrombotic processes play a role not only as a sequel of arteriosclerosis, but also for its pathogenesis. Under this aspect a pharmacological regulation of the course of the reaction of thrombpcytes, the blood coagulation and the fibrinolysis gets significance. The prevention of the formation of fibrin by well-known anticoagulants, such as coumarines and heparin, seems little suited for a prophylaxis of arteriosclerosis. By a pharmacological regulation of the reaction of the blood platelets which are decisive for the initial phase of the formation of thrombi new possibilities for an intervention into the pathomechanisms of arteriosclerosis are the result. Her also realizations concerning the prostaglandin metabolism of the blood platelets and of the wall of vessels can be evaluated. The activation of fibrinolysis by means of the hitherto introduced fibrinolytics, such as streptokinase and urokinase, is used above all for the treatment of acute thrombi. In the sense of a prevention of arteriosclerosis the activation of the endogenic fibrinolysis with the help of indirect fibrinolytics, which effect a liberation of the activators of fibrinolysis localised in the wall of the vessels, is a hopful way.
