Özet
Aim: Increased arterial stiffness is strongly associated with cardiovascular diseases, while thrombotic events are more common than hemorrhagic events in hypertensive patients. Markers of a hypercoagulable state may also predict future cardiovascular events in hypertensive patients. Here, we speculated that increased arterial stiffness might lead to the development of a hypercoagulable state that can play a role in the thrombotic complications of hypertension. Soluble endothelial protein C receptor (sEPCR) is one such marker of hypercoagulation. The ambulatory arterial stiffness index (AASI) could be accepted as a non-invasive measure of arterial stiffness. The aim of this study was to investigate association of AASI with levels of sEPCR in newly diagnosed hypertensive patients. Materials and methods: The study included 263 newly diagnosed essential hypertensive patients and 55 healthy normotensive controls. All subjects underwent 24 h ambulatory blood pressure monitoring (ABPM); the AASI was derived from ABPM tracings. Plasma sEPCR was measured by ELISA. Results: Hypertensive patients (n=263) had higher AASI, C-reactive protein (CRP) and sEPCR versus the normotensive healthy group (n=55). Univariate analysis showed that AASI was positively associated with age (r=0.212, p< 0.001) body mass index (r=0.412, p<0.001), pulse pressure (r=0.350, p<0.001), plasma sEPCR (r=0.894, p<0.001), 24-h heart rate (r=0.176, p=0.001) and inversely related to high-density lipoprotein (HDL) (r=-0.293, p<0.001). Multivariate analyses revealed that sEPCR and HDL are independently correlated to AASI. Conclusion: We suggest that increased AASI is associated with elevated sEPCR. It might be responsible for subsequent thrombotic events in newly diagnosed hypertensive patients.
