Introduction:

The thyroid hormone acts as a regulator of lipids in metabolism and can affect the development of cardiovascular diseases and dyslipidemia.

Objective:

To determine the prevalence of hypothyroidism in patients older than 35 years, diagnosed with some dyslipidemia, with or without pharmacotherapy.

Materials and methods:

Cross-sectional study in which the lipid and thyroid profile of 206 patients, with some type of dyslipidemia, in a health delivery center of Manizales, was analyzed between January 15 and June 15, 2013; prior informed consent and completion of a survey were requested.

Results:

81.1% of participants had hypercholesterolemia that was not controlled with a commercial reference and 49% were considered hypercholesterolemic in relation to the ATP III reference value. Two participants (0.97%) had clinical hypothyroidism caused by low levels of FT4 and 8 (3.9%) had subclinical hypothyroidism due to TSH levels greater than 6.16 μIU/ml.

Conclusions:

The valuation of TSH levels in men and women over 35, with alterations in lipid metabolism, is recommended.
