Prothrombin activation fragment 1 + 2 and thrombin-antithrombin-III complexes in plasma of patients with essential arterial hypertension.

Prothrombin activation fragment 1 + 2 (F1 + 2) and thrombin-antithrombin-III complexes (TAT) were measured in plasma of 34 patients with newly diagnosed essential hypertension. The patients with hypertension showed an increase in both F1 + 2 and TAT concentrations. The obtained results point to the intravascular thrombin generation in very early stages of essential hypertension.
