The aim of this study was to evaluate the fibrinolytic system by measurement of fibrinogen, plasminogen, tissue-type plasminogen activator (t-PA), and plasminogen activator inhibitor-1 (PAI-1) in healthy normotensive subjects and in patients with essential hypertension. A group of 21 healthy normotensive subjects [age, 39.2 +/- 1.8 years; 8 males, 13 females; body mass index (BMI) = 27.9 kg/m] and 42 patients with untreated essential hypertension (age, 47.6 +/- 1.7 years; 19 males, 23 females; BMI = 28.3 kg/m) were studied. Blood samples and clinical measurement were taken between 7 am and 9 am by an observer in a blind fashion. The systolic/diastolic blood pressure of normotensive subjects was 121.3 +/- 2.5/78.4 +/- 1.3 mm Hg and that of hypertensive patients was 166.4 +/- 4.3/102.9 +/- 1.83 mm Hg, measured in the sitting position. Plasma fibrinogen levels in the normotensive and hypertensive individuals were 295.7 +/- 9.4 mg/dL and 305.67 +/- 10.9 mg/dL, respectively (P = 0.456). The corresponding values for plasminogen were 71.4 +/- 3.8% and 89.5 +/- 2.5%, (P = 0.0031), for t-PA were 6.3 +/- 0.5 ng/mL and 7.6 +/- 0.4 ng/mL (P = 0.0487), and for PAI-1 were 46.9 +/- 5.1 ng/mL and 63.0 +/- 5.6 ng/mL (P = 0.0324), respectively. In conclusion, patients with essential hypertension have disequilibrium in the fibrinolytic system with a tendency toward a hypercoagulability state when compared with normotensive subjects. This state could explain, in part, the thrombotic complications that occur with a higher frequency in hypertensive patients as compared with normotensive subjects.

We studied specific features of erythrocyte membrane response to short-term occlusion of the brachial artery in patients with cardiovascular pathology. Under ischemic conditions, processes of sorption were primarily intensified in patients with effort angina and processes of hemoglobin binding with erythrocyte membrane predominated in patients with essential hypertension. These changes in the cell membrane were related to modulation of aggregation properties of erythrocytes (in patients with angina) and plasminogen activity (in patients with essential hypertension). They can also be associated with changes in glucose levels (effort angina) and uric acid (essential hypertension) whose effects can be significantly modified by other endogenous factors.
