[Subclinical hypothyroidism and cardiovascular risk].
OBJECTIVE
To assess whether subclinical hypothyroidism can behave as a cardiovascular risk factor or a modifier thereof, identifying epidemiological variables and estimated in a sample of patients diagnosed in the province of Albacete (Spain) cardiovascular risk.


METHODS
Observational, descriptive study was carried out in Albacete during the first half of January 2012 in patients of both genders with subclinical hypothyroidism. The following variables were analyzed: Fasting glucose , total cholesterol , HDL cholesterol, LDL cholesterol , triglycerides , TSH , T4 , weight, height, Body Mass Index , blood pressure, a history of cardiovascular disease , cardiovascular risk factors and estimated cardiovascular risk.


RESULTS
326 patients younger than 65 years at 78% without cardiovascular risk factors in 48.61 %, with female predominance (79.2 %). The prevalence of cardiovascular risk factors was identified: smoking (33.2 %), diabetes mellitus (24.9%), hypertension (23.4 %), lipid abnormalities (28.9%) and atrial fibrillation (4,9%). No association between subclinical hypothyroidism and most lipid profile parameters that determine a pro- atherogenic profile, except with hypertriglyceridemia was found. Likewise, neither association with increased cardiovascular risk was found.


CONCLUSIONS
The profile of patients with subclinical hypothyroidism is a middle-aged woman with no cardiovascular risk factors in half of cases. It has been found relationship between subclinical hypothyroidism and hypertriglyceridemia, but not with the other parameters of lipid profile, other cardiovascular risk factors or with increased risk. However, 25% of diabetics and 22% of non-diabetics are at moderate to high cardiovascular risk.
