Elevated serum lipoprotein(a) in subclinical hypothyroidism
Objectives. Asymptomatic lymphocytic thyroiditis and subclinical hypothyroidism are associated with increased risk for coronary artery disease. The present study aimed at evaluating serum lipoprotein(a)(Lp(a)), measured as apo(a), and other lipid parameters in 32 subjects with asymptomatic subclinical hypothyroidism. Subjects. Thirty-two Chinese subjects with asymptomatic subclinical hypothyroidism were compared to 96 age and sex-matched healthy controls. Results. Subclinical hypothyroid patients had higher (P 5.2 mmol/l in 10; TC > 5.2 mmol/l and TG > 2.3 mmol in six) as compared to 21 (20.8%) in the control group (P < 0.005). Subjects with TSH ≥ 11.0 mIU/l had significantly higher TC/HDL and LDL/HDL ratios. A significant correlation was observed between TSH levels and TC/HDL ratios (r = 0.455, P < 0.01). Conclusions. Subclinical hypothyroidism is associated not only with elevated LDL-cholesterol levels and low HDL-cholesterol levels but also with elevated lipoprotein (a). This may further increase the risk development of atherosclerosis.link_to_subscribed_fulltex
