Of these, 192 women and 164 men had thyrotropin levels within the clinical reference range of 0.50 to 3.5 mIU / L.

Methods In a Norwegian population - based cohort study, we prospectively studied the association between thyrotropin levels and fatal CHD in 17 311 women and 8002 men without known thyroid or cardiovascular disease or diabetes mellitus at baseline.

Overall, thyrotropin levels within the reference range were positively associated with CHD mortality (P for trend =.01); the trend was statistically significant in women (P for trend =.005) but not in men.

Treatment of patients with thyrotropin levels at or below 10 mIU / L without symptoms may cause more harm than good and may represent overtreatment.

American Thyroid Association guidelines recommend considering levothyroxine therapy at thyrotropin levels of 10 mIU / L or less when there are clear symptoms of hypothyroidism, positive thyroid autoantibodies or evidence of atherosclerotic cardiovascular disease (hardening of the arteries) or heart failure.

The study findings indicate that between 2001 and 2009, the median (midpoint) thyrotropin level at the start of levothyroxine treatment declined from 8.7 to 7.9 mIU / L, with an increase in the odds of having levothyroxine therapy start at a thyrotropin level of 10 mIU / L or less.

Compared with women in the lower part of the reference range (thyrotropin level, 0.50 - 1.4 mIU / L), the hazard ratios for coronary death were 1.41 (95 % confidence interval [CI], 1.02 - 1.96) and 1.69 (95 % CI, 1.14 - 2.52) for women in the intermediate (thyrotropin level, 1.5 - 2.4 mIU / L) and higher (thyrotropin level, 2.5 - 3.5 mIU / L) categories, respectively.

When thyroid hormone levels are too low, your brain's hypothalamus releases thyrotropin - releasing hormone (TRH), which stimulates the adjacent pituitary gland to produce thyroid - stimulating hormone (TSH).

When thyroid hormone levels are low, the hypothalamus produces a hormone called thyrotropin - releasing hormone or TRH.
