Protein C antigen and amidolytic activity were assayed in 38 patients with essential hypertension at the first stage of disease. As compared to 20 normal healthy blood donors no abnormality was found.

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.

Undesirable changes of haemostasis induced by some anti-hypertensive drugs can encourage the acceleration of atherogenesis. Therefore, the changes of haemostasis parameters in 22 patients with essential hypertension under long-term celiprolol therapy (> 2 months) were of interest. In the placebo group of 15 essentially hypertensive patients there were no significant changes in platelet activity. On the other hand, the therapeutic dose of celiprolol was shown to reduce total platelet aggregation, without any harmful effects on fibrinolytic activity and coagulation inhibitors such as protein C and antithrombin III. The metabolic neutrality of celiprolol accompanied by the proven platelet-inhibitory tendency is desirable in the new approach to hypertension treatment. Potentially anti-thrombotic or at least neutral prothrombotic properties of celiprolol may be important in terms of the favourable role of anti-hypertensive drugs in cardiovascular morbidity.

This study was designed to investigate both resistance to activated protein C (APC-R) and the factor FV Q506 mutation incidence in patients with a history of acute myocardial infarction (AMI) and patients with primary hypertension (PH), a high-risk group for arterial thrombosis. Eighty patients with a history of AMI (group A), 160 patients with a history of PH (group B), and 124 age-matched controls without arterial disease (group C) were studied. APC-R was determined using the Coatest APC Resistance Kit of Chromagenix, Sweden. The prevalence of the FV Q506 mutation was estimated by DNA analysis (Bertina method). The prevalence of the FV Q506 mutation was 20%, 13.75%, and 8% in groups A, B, and C, respectively (A v C P = .0466). The prevalence of APC-R was 47.5% in group A v 13% in group C (P < .0001) and 36.25% in group B v 13% in group C (P < .0001). The response to activated protein C expressed as mean value +/- SD was 2.05 +/- 0.33 in group A v 2.56 +/- 0.46 in group C (P < .05) and 2 +/- 0.22 in group B v 2.56 +/- 0.46 in group C (P < .05). These findings suggest that patients with a history of AMI or PH have a significantly increased incidence of both APC-R and FV Q506 mutation compared with the control group. These findings support the hypothesis that these anticoagulant defects may be risk factors for arterial thrombosis.

Endothelial damage, platelet hyperactivity and other changes of blood coagulation may play a role in the vascular complications of essential hypertension. Undesirable changes of haemostasis induced by some anti-hypertensive drugs can encourage the acceleration of atherogenesis. Therefore, the effect of angiotensin-converting enzyme (ACE)-inhibitors on haemostasis is of interest. The therapeutic dose of perindopril was previously shown to reduce platelet aggregation. In the present study, selected parameters of haemostasis were investigated in 23 patients with first and second stage of non-treated essential hypertension. The measurements were carried out before therapy, after 1 week of placebo administration, and after 1 week and after 1 month of ACE-inhibitor perindopril therapy in a once-daily dose of 4 mg. Plasma prothrombin time, activated partial thromboplastin time, fibrinogen level, plasminogen and antithrombin III activities, protein C and free protein S antigens, total fibrinolytic activity as well as fibrin monomers and D-dimers were assayed. There were no significant changes in any haemostasis variables investigated following placebo administration or perindopril therapy. On the basis of this study, no unfavourable effects on haemostasis induced by this therapy were found. The platelet-inhibitory effect of perindopril, without any harmful effects on coagulation or fibrinolytic activity and coagulation inhibitors, is desirable in the new approach to hypertension treatment. These properties of perindopril may be important in terms of the beneficial role of anti-hypertensive drugs in cardiovascular morbidity.

It has been previously shown that essential hypertension (EH) is associated with coagulation-fibrinolytic balance disorders. Our study was conducted in order to investigate disturbances in coagulation-fibrinolysis in offsprings of hypertensive parents. Two groups were studied: 44 healthy normotensive individuals (17 male, 27 female, age range 12-22 years) with a documented family history of hypertension and 33 individuals (14 male, 19 female, age range 11-21 years) without a family history of essential hypertension. The following parameters were determined in both groups: plasminogen activator inhibitor-1 antigen, tissue plasminogen activator antigen, fibrinogen, fibrin degradation products, thrombomodulin, protein S antigen, protein C activity, von Willebrand factor Ag, factor VII and factor XII activity. Additionally, systolic and diastolic blood pressure, insulin levels, blood lipids and heart rate were determined. The two groups were not found to have differences with respect to age, gender, body mass index, blood lipids and insulin levels. Hypertensive offsprings had significantly higher plasma levels of plasminogen activator inhibitor-1 antigen, fibrinogen, fibrin degradation products, protein S antigen and factor XII activity, while no differences were observed to the other haemostatic variables studied. Hence, offsprings of hypertensives had significantly higher diastolic blood pressure and heart rate. In conclusion, alterations regarding blood pressure, heart rate and fibrinolytic function exist in offsprings of hypertensive parents compared to individuals without family history of hypertension.
