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.
