Evaluation of epicardial fat tissue thickness in patients with Hashimoto thyroiditis

Summary Objective Hypothyroidism, whether overt or subclinical, has multiple effects on the cardiovascular system. Epicardial fat tissue (EFT) is closely related to cardiovascular disorders and atherosclerosis. Our study aimed to assess EFT thickness and carotid artery intima‐media thickness (CIMT) in patients with Hashimoto's thyroiditis (HT) displaying overt and subclinical hypothyroidism (SCH). Design and patients The study included 33 patients with SCH and 24 patients with overt hypothyroidism (OH) with HT as well as 32 healthy controls. EFT thickness, CIMT, thyroid hormone levels and lipid parameters were measured in all subjects. Correlation analysis and linear regression analysis were performed for EFT thickness. Results Mean EFT thickness was 2·89 ± 0·38, 3·53 ± 0·92 and 4·56 ± 1·61 mm in control, SCH and OH groups, respectively (P
