踝肱指数评价老年男性高血压患者下肢动脉病变的临床意义

目的通过测量踝肱指数（ABI）评价老年男性高血压患者下肢外周动脉病（PAD）的患病情况,并对发生高血压和PAD的共同危险因素进行评价。方法选取我院老年男性高血压患者264例,按ABI〈0.9者入选PAD组（88例）,ABI≥0.9者为非PAD组（176例）。比较两组患者年龄、身高、体质量、血压、ABI、BMI、共患病情况及是否吸烟等指标。结果 264例患者中ABI异常88例,检出率为33.3%。PAD组的冠心病、高脂血症、糖尿病、吸烟的检出率分别为77.27%、35.22%、51.13%6、5.90%,高于非PAD组的62.50%2、1.59%、33.52%和19.88%,P值分别为0.018,0.025,0.0070,.000。通过PAD患病率危险因素Logistic回归分析,年龄、冠心病、高脂血症、糖尿病、吸烟为独立危险因素（P〈0.05或P〈0.01）。结论老年男性高血压患者有较高的PAD发生率,其合并有冠心病、高脂血症、糖尿病、吸烟的检出率远高于非PAD高血压患者。ABI可用于早期诊断其下肢血管病变。

The clinical value of ankle brachial index in the evaluation of peripheral artery disease in patients of aged men with hypertension

Objective To evaluate the prevalence of peripheral arterial disease（PAD） in patients of aged men with hypertension by measuring the ankle-brachial index（ABI）.Methods A total of 264 patients of aged men with hypertension were recruited in the study.The patients were divided into PAD group（ABI0.9） and non PAD group（ABI≥0.9）.Age,height,weight,body mass index,blood pressure concomitant diseases and smoking status were recorded.Results The incidence of ABI0.9 in the total subjects was 33.3%.The incidences of CHD,hyperlipidemia,diabetes,tobacco use in PAD group were significantly higher than those in non PAD group.Conclusions PAD is highly prevalent among the patients of aged men with hypertension and more popular in the patients with other risk factors added.It was related the age,CHD,diabetes and tobacco use to patients of aged men with hypertension.Detection of ABI could early make the diagnosis of PAD to the patients of aged men with hypertension.
