Background: Because of its high prevalence, subclinical hypothyroidism (SCH) has clinical significance as it is associated with many of the risks of atherosclerotic cardiovascular disease (CVD) due to its direct and indirect effect on lipid profile, diastolic function, and endothelial dysfunction. However, the link between SCH and CVD is still unknown.Objectives: This study aimed to evaluate the carotid intima media thickness (CIMT) and the lipid profile as evidence of endothelial dysfunction and atherosclerosis on patients with SCH. Patients and methods: The current study was a cross-section study carried out on 50 patients with SCH who were enrolled from the
