title: Plasma concentration of coagulation and fibrinolysis factors and platelet function in hypertension.
abstract: Fifty-one patients with mild hypertension were evaluated in relation to the plasma concentrations of coagulation and fibrinolysis factors as well as for the aggregability of their platelets. In a considerable number of the patients (18/51), a significantly enhanced in vitro ADP (2 mumol/l)-induced aggregation was found. In the coagulation line significant increases could be demonstrated in fibrinogen, fibrin monomers and thrombin-antithrombin III. The fibrinolysis system showed significant increases for D-dimers, tissue plasminogen activator antigen and plasminogen activator inhibitor, whereas the tissue plasminogen activator activity was significantly diminished. Remarkably, there seems to be a discrepancy between the (low) tissue plasminogen activator activity and the (higher) plasminogen activator antigen concentration. Alterations in the plasma concentrations of the investigated coagulation and fibrinolysis factors and in the aggregability of the platelets are indicative of an involvement of coagulation, fibrinolysis and platelets in hypertension, which can be considered as partial risk factors for thrombophilia.
