Epidemiological study of hypothyroidism as cardiovascular risk in population

BACKGROUND: Prevalence of hypothyroidism (HT) markedly differs among various populations. We aimed to establish the prevalence of HT in the Czech population and to assess its association with conventional cardiovascular risk factors. METHODS AND RESULTS: 1240 subjects (629 m, 611 f; mean age 52.3); a random, population-based sample were evaluated. Cut-off points for thyroid parameters were defined as follows: thyreostimulating hormone (TSH) 0.58-3.65 mU/I, free thyroxine (fT4) 9-22 pmol/l and thyroid peroxidase antibodies (TPOAb) or = 55 years (2.08 (1.29-3.36)) or hypertension (1.80 (1.03-3.13)), and moreover, in males and females with positive TPOAb (5.81 (2.57-13.13) and 5.92 (3.38-10.36), resp.) CONCLUSIONS: Hypothyroidism was found in Czech population highly prevalent and it can contribute to the coronary risk, produced by conventional factors.
