BACKGROUND: Hypertension is one of the principal risk factors for cardiovascular disease. We aimed to evaluate the impact of hypertension on fibrinolytic balance and endothelial function by measuring plasma levels of plasminogen activator inhibitor-1 (PAI-1), tissue plasminogen activator antigen (tPA), tPA/PAI-1 complex and fibrinogen. METHODS: Patients enrolled into the study were divided into four groups: 22 essential hypertensive (EH), 22 white coat hypertensive (WCH), 22 renovascular hypertensive (RH) and 22 normotensive control subjects. Plasma PAI-1, tPA, tPA/PAI-1 complex levels were measured by enzyme linked immunosorbent assays. RESULTS: There was no difference in the systolic and diastolic blood pressure measurements of the EH and RH groups. The four groups were comparable for age, gender, smoking habits and BMI. Patients with EH, RH and WCH had increased plasma levels of PAI-1, tPA, tPA/PAI-1 complex and fibrinogen compared with controls. No fibrinolytic parameter was associated with blood pressure in hypretensive subjects. CONCLUSION: This prospective study showed that fibrinolytic markers such as PAI-1, tPA, tPA/PAI-1 complex are independently associated with the development of hypertension. This supports the hypothesis that disturbances in fibrinolysis precede a cardiovascular event. Therefore, hypertension may be associated with impaired fibrinolysis.
