title: [Study on the correlation of lower extremity arterial vessels by ultrasonography and atherosclerosis detection indicators].
abstract: OBJECTIVE
  To examine the correlation between lower extremity artery ultrasound and arteriosclerosis detection indicators, including ankle-brachial index (ABI) and Cardiac Ankle Vascular Index (CAVI).
  
  
  METHODS
  According to the level of lower extremity arterial disease by ultrasonography, 320 patients were divided into 3 groups (normal group, mild lesions group and severe lesions group). Comparative analysis of the difference of arteriosclerosis detection indicators among the groups, including ABI and CAVI . To analyze the correlation of two test results and explore the risk factors of lower extremity atherosclerotic lesions.
  
  
  RESULTS
  To compare ABI among the three groups, the differences were statistically significant (P < 0.05 ) . Lower extremity arterial disease was negatively correlated with ABI and positively correlated with CAVI (P = 0.000 ). Using Logistic regression analysis: age, gender, diabetes, pulse pressure is the impact of lower extremity arterial disease risk factors.
  
  
  CONCLUSIONS
  ABI and CAVI can be used as reliable indicators for the screening of artery stenosis, occlusion and atherosclerosis, combined with color Doppler ultrasonography can improve the diagnosis rate of lower extremity arterial disease.
