Study on the value of color Doppler ultrasound scanner in screening peripheral artery atherosclerosis of undergraduates on campus / 中国医学装备

ABSTRACT

Objective:To explore the value of color Doppler ultrasound scanner in screening peripheral artery atherosclerosis(AS)of undergraduates on campus.Methods:From June 2020 to June 2022,a total of 300 college student volunteers were selected from Sichuan University of Arts and Sciences and Dazhou Vocational and Technical College,and they were divided into peripheral AS group(59 cases)and healthy control group(241 cases)according to the occurrence of peripheral AS.The general data and blood flow parameters of the two groups were compared,and the risk factors of peripheral AS of undergraduates on campus were further analyzed.Results:The differences of the gender,hyperglycemia rate,hypertension rate,smoking history rate,triglycerides(TG),total cholesterol(TC)and high-density lipoprotein cholesterol(HDL-C)between the AS group and the healthy control group were not statistically significant(P>0.05).The differences of age,obesity rate,hyperlipidemia rate and low-density lipoprotein cholesterol(LDL-C)between AS group and healthy control group were statistically significant(t=6.666,x2=4.256,5.292,t=4.515,P<0.05),respectively.The maximum blood flow velocity(Vmax)and minimum blood flow velocity(Vmin)of the AS group were lower than those of the healthy control group,with statistically significant differences(t=-3.753,-3.905,P<0.05).The resistance index(RI)of the AS group was higher than that of the healthy control group,with statistically significant differences(t=3.126,P<0.05).The dependent variable of the AS group was assigned a value of 1,and the healthy control group was assigned a value of 0.The factors with P<0.05 in univariate analysis were used as independent variables.The multiple factor binary logistic analysis showed that age and high LDL-C were risk factors for peripheral AS(OR=1.664,1.192,P<0.05),while high Vmax and high Vmin were protective factors for peripheral AS(OR=-0.102,-0.170,P<0.05),respectively.Conclusion:The higher the LDL-C level,the lower the Vmax and Vmin,are the higher risks of undergraduates who occur peripheral AS.The LDL-C and ultrasonic blood flow parameters(Vmax and Vmin)can be used to assist the diagnosis about whether occurs peripheral AS.
