Endothelial damage, high fibrinogen levels, and platelet activity are the important accelerating factors for the development of hypertension (HT). von Willebrand factor (vWF; endothelial damage marker), fibrinogen levels, and platelet aggregability were compared between patients with uncomplicated, mild-to-moderate hypertension and healthy subjects. The relationship between traditional cardiovascular risk factors and endothelial damage and prothrombotic state was evaluated. One hundred sixty-nine (54 males, 115 females) patients with untreated and uncomplicated mild-to-moderate HT, and age, gender, and body mass index-matched 124 (58 males, 83 females) healthy subjects were enrolled in this study. Plasma vWF, fibrinogen levels, adenosine diphosphate-induced platelet aggregability, insulin, glucose, serum lipids, and uric acid were measured. Patients with HT had significantly increased fibrinogen, vWF, platelet number and aggregability induced by adenosine diphosphate, triglycerides, total/HDL-C, glucose, uric acid levels, and insulin resistance than control group. vWF and hemostatic markers were comparable between smoker and nonsmoker subjects. Platelet aggregability was positively related to systolic and diastolic blood pressure, and vWF. Fibrinogen was positively associated with body mass index (BMI), systolic and diastolic blood pressure, total cholesterol (TC), uric acid, vWF, and insulin resistance. vWF was significantly related to age, systolic blood pressure, TC, LDL-C, and total/HDL-C. Systolic blood pressure was independently related to vWF. vWF and diastolic blood pressure were significant predictors for adenosine diphosphate-induced platelet aggregability. Systolic blood pressure and vWF were independent predictors for fibrinogen levels. Uncomplicated mild-to-moderate HT had endothelial damage and is associated with a prothrombotic state. Traditional cardiovascular risk factors such as age, BMI, dyslipidemia, and insulin resistance are important contributors to the development of endothelial damage and a prothrombotic state. Therefore, it is important to control these cardiovascular risk factors along with proper treatment of HT for preventing target organ damage in mild-to-moderate HT.
