Moon S, et al. - Researchers studied the link between subclinical hypothyroidism (SCH) and cardiovascular (CVD) events, and mortality, using the atherosclerotic CVD risk (ASCVD) risk score in this observational study. Participants were aged ≥ 40 years at baseline from the Ansung cohort of the Korean Genome and Epidemiology Study, and followed up for 12 years. With a cutoff age of 65 years or 7.5% of the 10-year ASCVD risk score, subgroup analysis was carried out. They found an association of high TSH levels with an increased risk of mortality and new CVD risks. This association was specifically seen among subjects with high CVD risk.
