初诊2型糖尿病患者踝肱指数的影响因素

The Factors Influencing Ankle Brachial Index in Newly Diagnosed Patients with Type 2 Diabetes

目的探讨初诊2型糖尿病(T2DM)患者踝肱指数(ABI)的影响因素。方法采用多普勒血流探测仪检测初诊190例T2DM患者足背动脉、胫后动脉与肱动脉血压的比值,即ABI值,采用逐步回归分析其影响因素。结果 190例T2DM患者中ABI<0.9的29例,占15%,回归分析显示,年龄、高血压病程、低密度脂蛋白为ABI的影响因素(p均<0.05)。结论 ABI检测诊断初诊T2DM下肢动脉病变简便可靠,年龄、病程、低密度脂蛋白、高血糖、高血压为下肢动脉病变的主要危险因素。

Objective： To figure out the factors influencing Ankle Brachial Index in newly diagnosed patients with Type 2 diabetes. Methods： Ankle Brachial Index of the 190 newly diagnosed patients with Type 2 diabetes was evaluated by Doppler ultrasonic blood stream detector. Stepwise regression analysis was applied to explore the influencing factors. Results： There were 29 patients with Ankle Bracbial Index less than 0.9, the percentage was 15%. The results of stepwise regression analysis showed that age, hypertension duration, low density lipoprotein affected tile Ankle Brachial Index （all ps〈0.05）. Conclusion： Measuring Ankle Brachial Index was a simple and precise method for diagnoses of pathological change of the artery of low limbs caused by Type 2 diabetes. Age, diabetes duration, low density lipoprotein, hyperglycemia, and hypertension are the major risk factors of pathological change of the artery of low limbs caused by Type 2 diabetes.
