目的 探讨高踝肱指数(ABI)与糖尿病患者微血管并发症发生的相关性.方法 选择2009年3月至2012年3月就诊的2型糖尿病患者共1360例,均行ABI测定,按ABI水平分为ABI＜ 0.7组、ABI 0.7～0.9组、0.9＜ ABI≤1.3组以及ABI＞ 1.3组,对ABI与糖尿病患者微血管并发症发生的关系进行单因素分析和Logistic回归分析.结果 0.9＜ ABI≤1.3组患者1260例,ABI＜0.7组患者20例,ABI 0.7 ～ 0.9组患者60例,ABI＞ 1.3组患者20例.Logistic回归分析显示与ABI高水平相关的因素是吸烟和收缩压(P＜0.05).而ABI高水平与微血管并发症糖尿病肾脏病变、糖尿病周围神经病变和糖尿病视网膜病变无明显相关性.结论 无糖尿病大血管病变的2型糖尿病患者,ABI高水平并没有增加动脉粥样硬化的危险,且不增加微血管并发症发生率.“,”Objective To explore the correlation between high ankle brachial index (ABI) and microvascular complications in patients with diabetes.Methods A total of 1360 patients with type 2 diabetes mellitus were selected from March 2009 to March 2012.ABI test was performed in all the patients.The patients were divided into ABI ＜ 0.7 group,ABI 0.7-0.9 group,0.9 ＜ ABI ≤ 1.3 group and ABI ＞ 1.3group according to the ABI level.The correlation between ABI and microvascular complications in patients of type 2 diabetes mellitus was analyzed by single factor analysis and Logistic regression analysis.Results A total of 1260 patients were in 0.9 ＜ABI ≤1.3 group,20 patients in ABI ＜0.7 group,60 patients in ABI 0.7-0.9 group,and 20 patients in ABI ＞ 1.3 group.Logistic regression analysis showed that related factors of the high ABI level were smoking and systolic blood pressure (P ＜ 0.05).The high ABI level showed no correlation with microvascular complications such as diabetic nephropathy,diabetic perineuropathy and diabetic retinopathy.Conclusion In patients with type 2 diabetes mellitus and without diabetic macroangiopathy,the high ABI level does not increase the risk of atherosclerosis and the incidence of microvascular complications.
