Arterial stiffness is independently related to increased cardiovascular risk in the hypertensive population. The aim of the present study was to investigate whether various stages of abnormal glucose metabolism may differently affect arterial stiffness in hypertensive patients and whether there is any difference in arterial stiffness among patients with normal glucose regulation. We studied 1375 never-treated hypertensive subjects. Participants were divided into four metabolic groups: normal glucose regulation (NG), impaired fasting glucose, impaired glucose tolerance and type-2 diabetes mellitus (DM 2). Hypertensive subjects with NG were subdivided into three groups according to glucose levels. Arterial stiffness was estimated by carotid-femoral pulse wave velocity (PWV). PWV showed a significant increase from patients with NG to DM 2 (from 7.74 ± 1.38 to 8.40 ± 1.30 to 8.86 ± 1.30 to 10.09 ± 2.07 m/s respectively, p<0.001). Among hypertensive subjects with NG there was an increase in PWV from low normal to high normal values of glucose (p<0.01). PWV was independently related to all glucose metabolic parameters (p<0.001 for all). In the present study, we demonstrated an association between arterial stiffness and glucose tolerance in hypertensive subjects. Given the prognostic significance of arterial stiffness, aims should be towards closer monitoring and intensive care of hypertensive patients with abnormal glucose metabolism.
