RESUMO
Objective To investigate the correlation of intima-media thickness (IMT) of the lower peripheral arteries and maximal shear rate (SR) in diabetic (DM) patients and to analyze the related risk factors.Methods A total of 84 diabetic patients and 46 controls were recruited in the study.Color Doppler ultrasonography technique was applied to observe the IMT,diameter(D) and hemodynamics of the lower peripheral arteries and the comparison with biochemical parameters was carried out in order to reveal their correlation to the pathological changes of vascular in DM patients.ResultsIn DM group,the SR was lower than that in control group (P＜0.05).The risk factors related to the lower peripheral arteries of DM patients also were significant difference to that of control group (P＜0.05).Conclusion The decrease of SR in diabetes patients can cause the thicker IMT,which is one of the important factors leading to atherosclerosis and is correlated to various risk factors for metabolic syndrome.
