Title: Evaluation of correlation between carotid artery elasticity and lower extremity atherosclerosis in patients with diabetes mellitus by echo tracking technique
Abstract: Objective:To investigate the correlation between carotid artery elasticity and lower extremity atherosclerosis(LEA)in patientswith diabetesmellitus(DM)by echo tracking technique(ET).Methods 116 patientswith diabetes mellituswere examined by ETtechnique and vascular ultrasound technology,All the caseswere divided into non-LEA group(group A:control group)and four groups(B,C,D and E)according to the degree of stenosis of lower extremity arterial by vascular ultrasound examination.All the carotid artery elasticity parameters included(pressure strain elastic modulus, Ep)、(stiffness parameter,β)、(arterial compliance,AC)、(augmentindex,AI)、(pulsewave conductingvelocity,PWVβ)obtained by ETin the five groupswere measured respectively.ResultsThe value of Ep、β、PWVβ in the LEAgroupswere significantly higher than those in the control group,and the AC value were significantly lower than those(P 0.01或P0.05),Ep、β、PWVβ value increased significantly with the increase in the degree of stenosis of lower extremity arteria(P 0.01或P 0.05),There were no significant difference among the five groups about AI(P 0.05).Conclusions The echo tracking technique can reveal the correlation between carotid artery elasticity and lower extremity atherosclerosis in patientswith diabetesmellitus,it is an effective method in evaluating lower extremity atherosclerosis in diabetesmellitus patients.
