踝肱比测定在2型糖尿病患者下肢动脉病变诊断中的临床意义

The Clinical Significance of ABI for the Diagnosis of LEAD in Type 2 Diabetes Mellitus

目的:探讨踝肱比(ABI)测定在诊断2型糖尿病患者下肢动脉病变中的临床意义。方法:采用多普勒血流探测仪检测2型糖尿病患者足背动脉、胫后动脉与肱动脉血压的比值,以ABI<0.9为切割点将患者分为低ABI组与对照组,分析比较两组代谢参数。结果:121例2型糖尿病患者中ABI<0.9的患者22例,占总例数18%,低ABI组与对照组相比,其年龄、糖尿病病程、HbA1C及LDL明显增高,低ABI组患者下肢血管彩超显示均有不同程度的动脉硬化改变。结论:ABI是诊断2型糖尿病下肢动脉病变的一种简易而经济的方法,年龄、病程、HbA1C及LDL为下肢动脉病变的主要危险因素。

Objective：To investigate the clinical significance of Ankle-Brachial Index（ABI）in the diagnosis of lower extremity arterial disease（LEAD） in type 2 diabetes mellitus.Methods：ABI was examined in the 121 patients with type 2 diabetes.The patients were divided into the group with low ABI（ABI 0.9）、and the group with normal ABI（ABI≥0.9）.The two groups were compared for clinical parameters.Results：22 of the 121 patients had low ABI,the rate of low ABI was 18%;the age,duration of diabetes,HbA1C and LDL in low ABI group were significantly higher than those in normal ABI group;ultrasonic examination showed that all the patients in low ABI group had different vascular lesions in the lower limbs.Conclusions：ABI is an easy and economical method for diagnosing LEAD in patients with type 2 diabetes.the older age,longer duration of diabetes,higher levels of HbA1C and LDL are the risk factors of the patients with abnormal ABI in type 2 diabetes.
