The study on microalbuminuria and the thickness of carotid artery intima-media in patients with subclinical hypothyroidism / 中国基层医药

ABSTRACT

Objective To observe the level of urinary microalbumin(MAU) and carotid artery intima-media thickness(CIMT) in patients with subclinical hypothyroidism,and to explore the relationship between subclinical hypothyroidism and MAU,arteriosclerosis.Methods 70 patients with subclinical hypothyroidism were randomly divided into the two groups according to the level of CIMT.33 patients were selected as the arteriosclerosis group and 37 patients were selected as the non-arteriosclerosis group,and 30 healthy people were selected as the control group.The levels of FT3,FT4,TSH,blood fat,MAU,CIMT observed.Results Compared with the healthy controls,the levels of TC,TG,LDL-C,CIMT were significantly higher in the arteriosclerosis group (P =0.008,0.007,0.009,0.006),the level of HDL-C was significantly lower in the arteriosclerosis group(P =0.006).The levels of TC,TG,LDL-C,CIMT were significantly higher in the non-arteriosclerosis group (P =0.042,0.037,0.008,0.035),the level of HDL-C was significantly lower in the non-arteriosclerosis group(P =0.038).The levels of TC,TG,LDL-C,CIMT in arteriosclerosis group were significantly higher than those in the non-arteriosclerosis group (P =0.032,0.041,0.039,0.007).The level of HDL-C in the arteriosclerosis group was significantly lower than the non-arteriosclerosis group(P =0.044).The level of MAU had no significant difference among the three groups(P =0.052,0.087,0.092).TSH had no relationship with MAU (r =0.195,P ＞ 0.05),TSH had positive correlation with CIMT(r =0.578,P ＜ 0.01).Conclusion The patients with subclinical hypothyroidism have lipid metabolism disorder and CIMT incrassation,which can increase the risk of arteriosclerosis.
