Abstract:
Objective To investigate the relationship between thyroid hormone levels and carotid artery disease in maintenance hemodialysis ( MHD ) patients and evaluate its value. Methods Clinical data of one hundred and twenty?one MHD patients during January 2014 to July 2016 in Yanan University Affiliated Hospital were collected. The patients were divided into the normal carotid artery group and the carotid artery lesion group according to whether there was plaque or stenosis in the carotid artery ultrasonography. Clinical data related to the carotid artery lesions was collected, and the single factors that may affect the carotid artery lesions were analyzed,multivariate logistic regression was used to analyze independent risk factors for carotid artery disease, and the greatest independent risk factor of OR value was used to establish a ROC curve for evaluating carotid atherosclerosis in patients with MHD. Results The levels of serum calcium, TC, TG, LDL?C, TSH, CRP and Hcy in the carotid artery group were higher than those in the normal group ( P<0. 05 ) . The levels of serum phosphorus and FT3 in the lesion group were lower than those in the normal group ( P<0. 05 ) . Multivariate logistic regression analysis of risk factors for carotid atherosclerosis showed that CRP ( OR=1. 620,95%CI1. 288-2. 038,P=0. 048),Hcy (OR=1. 976,95%CI 1. 135?3. 441,P=0. 021),FT3 (OR=2. 521,95%CI 1. 584-4. 012,P=0. 017) were independent risk factors for carotid artery disease. FT3 evaluation of the ROC curve showed AUC=0. 848,P=0. 000,the cut?off value was 3. 705pmol/L,the diagnostic sensitivity was 0. 670,and the specificity was 0. 879. CRP valuation of the ROC curve suggested that AUC=0. 619,P=0. 000,the cut?off value was 16. 215 mg/L,the diagnostic sensitivity was 0. 932 and the specificity was 0. 333. Hcy evaluation of the ROC curve showed AUC=0. 767,P=0. 000,the cut?off value was 12. 565μmol/L,the diagnostic sensitivity was 0. 784 and the specificity was 0. 881. Conclusion Low concentration of FT3,high concentration of Hcy and high concentration of CRP in MHD patients were independent risk factors for carotid artery disease. The use of FT3 to evaluation the carotid atherosclerosis has a certain value.
