[Protein C and plasma serine protease inhibitors in patients with essential hypertension].

Plasma protein C and serine protease inhibitors together with some other hemostasis parameters have been determined in 60 patients with essential hypertension. Significant decrease in protein C and alpha 2-antiplasmin levels, increased fibrinogen, fibrinopeptide A, WF: Ag, plasminogen, and prolongation of euglobulin fibrinolysis time have been observed. Results indicate hypercoagulability and fibrinolysis defect in hypertensive patients.
