摘要
目的 探讨趾动脉压力指数 (toepressureindex ,TPI )对下肢动脉硬化症 (lowextremityatherosclerosisdisease ,LEASD)患者的诊断价值。方法 在我院住院的患者中随机选择 6 0岁以上男性高血压病患者 6 5例 ,年龄 6 0～ 93(76 .5 7± 5 .89)岁 ,其中LEASD患者 38例 ,无LEASD患者 2 7例 ,对所有患者行肱动脉压及趾动脉压测量 ,分别计算TPI。结果 (1)LEASD组患者的TPI值明显低于无LEASD组 ;(2 )与超声多普勒诊断结果比较 ,随着TPI取值的下降 ,诊断LEASD的敏感性逐渐增加、特异性逐渐下降 ;(3)诊断符合率以TPI≤ 0 .6 0时为最好。结论 TPI≤ 0 .6 0时高度提示有LEASD的可能。
Objective To evaluate the diagnostic value of the toe pressure index (TPI) for the lower extremity atherosclerotic disease (LEASD) in the aged male patients.Methods Sixty-five male patients were selected from our hospital during a period of 3 months.The mean age of them was 77(60～93) years. Thirty eight (group A) of them had lower extremity atherosclerotic disease defined by ultrasound Doppler.As matched control (group B), the other 27 cases were without LEASD. The same two doctors examined the toe pressure of all patients.According to the results of Doppler examination,the sensitivity, specificity, positive and negative predictive values, and diagnostic accordance rate for LEASD were compared for the different ranges of toe pressure index (TPI) values.The statistic analysis was performed using t-test and χ2 test in SPSS 8.0 format.Results(1)The values of TPI in group A were much lower than those in group B (P<0.01).(2)The diagnostic sensitivity for LEASD increased and the specificity decreased gradually with decreasing values of TPI.(3)The diagnostic accordance rate for LEASD was 70% with TPI≤0.60.Conclusion The LEASD should be supposed if TPI is less than or equal to 0.60.
