4.1 Our results
In this large prospective controlled study, we report a significant increase in the carotid intima-media thickness in adult patients with SCH when compared to healthy controls. In addition, carotid intima-media thickness showed a significant reduction following treatment with levothyroxine at a six-month follow-up. Based on these findings, the current study suggests that there is an increase in cardiovascular risk in SCH with TSH less or greater than 10 µIU/ml, and its treatment could potentially reduce this risk.
