Abstract:
Objective To explore the clinical value of wave intensity (WI) in evaluating early changes of cardiovascular function in patients with type 2 diabetes mellitus (T2DM).Methods Thirty T2DM patients without atherosclerosis by conventional ultrasonography were enrolled as case group,while thirty healthy volunteers were enrolled as control group.Two groups were well-matched in age and sex.Both of the case and control groups were taken WI test of carotid artery.The parameters of WI examinations in two groups were measured and compared.Results Compared to the control group,values of arterial stiffness index (β),elasticity modulus (Ep),pulse wave transit velocity (PWVβ),and decelerating wave intensity (W2) were significantly higher in T2DM group (P ＜0.05).Arterial compliance (AC) value was significantly reduced in T2DM group (P ＜0.05).Accelerating wave intensity (W1) value was higher in T2DM group without significant statistical differences (P ＞ 0.05).Conclusions WI technique which can early assess the changes of left ventricular function and vascular elasticity in T2DM patients has important clinical value.
