目的探讨2型糖尿病(T2DM)颈动脉血管弹性与糖尿病视网膜病变(DR)的关系。方法应用超声血管回声跟踪技术(ET)检测颈动脉内中膜厚度(IMT)在正常范围的经眼底荧光造影检查确诊为DR的T2DM患者的颈总动脉血管的各弹性参数,并进行相关性分析。结果颈动脉血管弹性参数β、Ep、AI测值越高,DR的发生率越高程度越重。结论T2DM患者颈动脉血管弹性参数的改变与DR的发生有密切关系。
Objective To investigate the relationship between carotid artery elasticity and diabetic retinopathy (DR) in type 2 diabetes mellitus (T2DM). Methods Echocardiography (ET) was used to detect the carotid artery intima - media thickness (IMT) in the normal range of fundus fluorescein angiography confirmed by DR of T2DM patients with common carotid artery elastic parameters and correlation analysis . Results The higher values of β, Ep, AI of carotid artery elasticity parameters were, the higher the incidence of DR was. Conclusion The changes of carotid artery elasticity parameters in T2DM patients are closely related to the occurrence of DR.
