PARRAGA MARTINEZ, Ignacio et al. Comorbidity and Cardiovascular Risk in Subjects with Initial Diagnosis of Hypercholesterolemia. Rev. Esp. Salud Publica [online]. 2011, vol.85, n.3, pp.305-313. ISSN 2173-9110.

Background: For a proper approach to the subjects, in which the presence of hypercholesterolemia is identified for the first time, is important to consider simultaneously both cardiovascular risk factors and the presence of other diseases. The purpose of our study was to describe the lipid profile of patients in which the presence of hypercholesterolemia is detected for the frist time and to determine their cardiovascular risk and comorbidity. Methods: Observational cross-sectional study in a Primary Care setting. In 274 subjects with a plasma cholesterol level higher or equal to 200 mg / dL ("limit" hypercholesterolemia), selected by consecutive sampling, we assessed: lipid profile, cardiovascular risk factors and cardiovascular risk (SCORE and Castelli's atherogenic index), comorbidity (Charlson's Index) and sociodemographic characteristics. Results: The mean cholesterol level was 232.9 mg/dl. Hypercholesterolaemia was reported "definite" (>= 250 mg / dl) in 21.1% (95% CI: 16.2 to 26.1). A 9.5% showed a cardiovascular risk >= 5%. Lipoprotein ratio of total cholesterol/HDL cholesterol was higher in men than in women (4.4 vs. 3.8, p <0.001) in subjects with Charlson's Comorbidity Index > = 1 (4.1 vs. 3.9, p = 0.04), in smokers (4.3 vs. 3.9, p = 0.04) and in hypertensive subjects (4.2 vs. 3.9, p = 0.03), obese (4.2 vs 3 , 7, p <0.05) or with the metabolic syndrome (4.4 vs 3.9, p = 0.02). We observed a higher proportion of subjects with moderate cardiovascular risk / high or cardiovascular disease in those with comorbidity (87.3% vs 42.3%, p <0.01). Conclusions: More than a third of the subjects in which "limit" cholesterol was identifiyed for the first time presents comorbidity, being "defined" hypercholesterolemia in 21.1% of the cases. Takeing in consideration the Score function assessment, one outif 10 subjects presents high cardiovascular mortality risk after 10 years. Both lipoprotein ratio and cardiovascular risk are markedly higher in subjects with comorbidity.
