Correlation analysis between trace element levels and carotid atherosclerosis / 中风与神经疾病杂志

ABSTRACT

@#To analyze the correlation between trace element levels and carotid atherosclerosis（CAS），explore the risk factors of CAS. Methods People who underwent physical examination，and performed carotid artery ultrasonography，trace element detection and inflammatory factors detection were collected from January 2020 to February 2022 in the Physical Examination Center of the First Hospital of Jilin University. 325 cases were selected in strict accordance with the inclusion and exclusion criteria，the subjects were classified into two groups according to carotid intima-media thickness（IMT）. There were 146 cases in the normal carotid artery group and 179 cases in the carotid atherosclerosis group. Chi-square test，t test and rank sum test were used to compare the differences in basic information，serum trace element levels，C-reactive protein（CRP） and blood biochemistry between the two groups；Spearman correlation analysis was used to explore the correlation between carotid IMT and trace elements，CRP and inflammatory factors；multivariate Logistic regression was used to analyze the risk factors of CAS；all tests were performed on two sides，and the difference was statistically significant at P<0.05.Results （1）The age，waist circumference，carotid IMT，systolic blood pressure，prevalence rate of diabetes，the ratio of smoking，drinking and male in the carotid atherosclerosis group were higher than those in the normal carotid artery group，and the difference was statistically significant（P<0.05）. （2）There were statistical differences（P<0.05） in the contents of CRP，iron，zinc，LDL-C，FBG and UA between the normal carotid artery group and the carotid atherosclerosis group. The contents of CRP，iron，LDL-C，FBG and UA in the carotid atherosclerosis group were higher than those in the normal carotid group，and the zinc content in the carotid atherosclerosis group was lower than that in the normal carotid artery group. （3）Carotid IMT was positively correlated with age，waist circumference，systolic blood pressure，diastolic blood pressure，iron，CRP，triglycerides，LDL-C，fasting blood glucose，uric acid，while negatively correlated with zincand ratio of zinc and copper. （4）Multivariate Logistic regression analysis of carotid atherosclerosis，the results showed that age，gender，the ratio of smoking，the ratio of drinking，CRP，zinc，LDL-C，and fasting blood glucose were risk factors for carotid atherosclerosis，and zinc was a protective factor for carotid atherosclerosis. Conclusion Trace element iron is positively correlated with carotid IMT，and the higher its level is，the higher the risk of CAS；the trace element zinc is negatively correlated with carotid IMT，and the higher its level is，the lower the risk of CAS is；zinc is a protective factor for CAS.
