Abstract
Objective: High levels of serum uric acid (SUA) and triglycerides (TG) might promote high-cardiovascular risk phenotypes, including subclinical atherosclerosis. An interaction between plaques Xanthine Oxidase (XO) expression, SUA, and HDL-C has been recently postulated Design and method: N = 6211 patients from the URic acid Right for heArt Health (URRAH) study with carotid ultrasound and without previous cardiovascular diseases (CVD), followed over 20 years, were included in the analysis. Hypertriglyceridemia (hTG) was defined as TG > = 150 mg/dL. Higher levels of SUA (hSUA) were defined as > = 5.6 mg/dL in men and 5.1 mg/dl in women Results: A carotid plaque was identified in 1742 subjects (28 %). SUA and TG predicted carotid plaque (HR 1.09 [1.04 - 1.27], p < 0.001 and HR 1.25 [1.09 - 1.45], p < 0.001) in the whole population, independently of age, sex, diabetes, systolic blood pressure, HDL and LDL cholesterol and treatment. Four different groups were identified (normal SUA and TG, hSUA and normal TG, normal SUA and hTG, hSUA and hTG). The prevalence of plaque was progressively greater in subjects with normal SUA and TG (23%), hSUA and normal TG (31%), normal SUA and hTG (34%), hSUA and hTG (38%) chisquare 0,0001) Logistic regression analysis showed that hSUA and normal TG [HR 1.159 (1.002 to 1,341); P = 0.001], normal SUA and hTG [HR 1. 305 (1.057 to 1.611); P = 0.001], and the combination of hUA and hTG [HR 1. 539 (1.274 to 1.859); P = 0.001], were associated with a higher risk of plaque Conclusions: Our findings demonstrate that SUA is independently associated with the presence of carotid plaque and suggest that the combination of hyperuricemia and hypertriglyceridemia is a stronger determinant of carotid plaque than hSUA or hTG taken as single wisk factors. The association between SUA and CVD events may be explained in part because of a direct association of UA with carotid plaqu
