摘要
目的 探讨踝动脉压力指数 (ankle armindex ,AAI)对老年下肢动脉硬化症 (LEASD)患者的诊断价值。方法 连续 3个月在我院住院的患者中选择 6 0岁以上男性高血压病患者 6 5例 ,其中LEASD患者 38例 ,无LEASD患者 2 7例。所有患者均接受下肢动脉超声多普勒检查 ,并测定AAI。以超声多普勒为标准 ,分别比较了AAI不同取值范围对LEASD的诊断价值。统计分析采用SPSS 8.0系统 ,t检验与 χ2 检验。结果 LEASD组患者的AAI值明显低于无LEASD组 ;与超声多普勒诊断结果相比 ,AAI≤ 0 .85时诊断符合率为最好。结论 (1)LEASD组患者的AAI值明显低于无LEASD组 ;(2 )在 6 0岁以上的无LEASD的男性患者中 ,AAI的平均值为 0 .98± 0 .2 7;(3)AAI≤ 0 .85时高度提示有LEASD的可能。
Objective To investigate the clinical diagnostic method for lower extremity atherosclerosis disease (LEASD),based on the measurements of ankle-arm index (AAI) in the aged male patients with hypertension.Methods Sixty-five male patients were selected from the General Hospital of Chinese People’s Liberation Army during a three-month period.The mean age was 77 years old.Of them,38 patients (group A) had lower extremity atherosclerosis disease (LEASD) as defined by ultrasound Doppler examination.In the control group (group B),27 cases had no LEASD.Throughout the research,two doctors took turns to examine the arteries in both legs with Doppler and to measur AAI.According to the results of Doppler examination,the diagnostic value for LEASD were compared for the different given value ranges of AAI.The statistic analysis was performed using t-test and χ 2 test in SPSS 8.0 format.Results The values of AAI in group A were much lower than those in group B.The diagnostic accordance rate for LEASD was 70% when AAI was ≤0.85.Conclusions (1)The values of AAI in group A were much lower than those in group B;(2)The mean of AAI was 0.98±0.27 in male patients over 60 years old without LEASD;(3)AAI≤0.85 suggests the possibility of presence of LEASD.
