The Application Value And Risk Factor Analysis Of Atherosclerosis Were Evaluated By Ultrasonography

Objective:Color doppler ultrasound was used to detect carotid atherosclerosis(CAS),to clarify risk factors and to guide early clinical intervention to prevent the occurrence of complications.Methods: Selected 2016-2017 of 372 cases with functional examination as the research object,according to the result of color doppler ultrasound imaging examination will be divided into the normal group(n=158),IMT thickening group(n=104)and plaque group(n=110).Improve the basic information and test results,detailed record client age,sex,high blood pressure,uric acid(UA),blood sugar,blood fat and BMI pathogenic factors such as situation,first of all,the comparison between the three groups each risk factor,and then into the multi-factor Logistic regression analysis,screening out of carotid artery atherosclerosis statistically significant risk factors.Results:1.The thickening of the carotid intima-medium film(1mm≤IMT ≤1.5mm): the intimal echo is enhanced,and the arterial wall is not only unitary or coarse.Carotid atherosclerotic plaques(IMT≥1.5mm): when the patch is single or multiple,tend to occur in the common carotid artery bifurcation and its nearby area(see figure 2,4),according to the size and uniformity of the echo can be divided into three types: weak echo(soft spot)(see figure 3),mixed echo plaques(mixed stain)(see figure 4)or strong echo(hard plaque)(see figure 2),with mixed stain,behind the plaque calcification with acoustic shadow,color doppler blood flow image display tube cavity filling is not completely,plaques have color filling defect.2.IMT thickened group compared with normal group: the history of high blood pressure,SBP,age,blood UA,HDL-C statistically significant(P< 0.05),gender,history of diabetes,DBP,TC,TG,LDL-C and there was no statistically significant difference BMI(P> 0.05).See table 13.Compared with the normal group,the results of the patch group were: history of hypertension,SBP,DBP,age,history of diabetes,blood UA and ldl-c were statistically significant(P<0.05).There was no significant difference in gender,TC,TG,hdl-c and BMI(P BBB 0.05).See table 2.4.Compared with IMT thickening group,the history of hypertension,SBP,age,history of diabetes and ldl-c were statistically significant(P < 0.05).There was no significant difference in gender,DBP,blood UA,TC,TG,hdl-c and BMI(P < 0.05).See table 35.Multivariate Logistic regression analysis showed that age,hypertension,and blood UA were risk factors for CAS.(P < 0.05).See table 4Conclusion:1.The formation of CAS is the result of multiple factors,which is closely related to the traditional risk factors such as age,hypertension,diabetes and dysplasia.2.Uric acid can be used as a new risk factor to evaluate CAS.3.Ultrasonography has high application value in the pathogenesis,plaque morphology and screening risk factors of CAS.
