Serum uric acid predicts progression of subclinical coronary atherosclerosis in individuals without renal disease.

Objective: To examine uric acid (UA) as a possible predictor of the progression of coronary artery calcification (CAC) using data from the prospective Coronary Artery Calcification in Type 1 Diabetes (CACTI) Study.
Research Design and Methods: CAC was measured by electron beam tomography at the baseline and at a follow-up 6.0±0.5 years later. The study population included 443 participants with type 1 diabetes and 526 control subjects who were free of diagnosed coronary artery disease at baseline. The presence of renal disease was defined by the presence of albuminuria and/or low glomerular filtration rate.
Results: In subjects without renal disease, serum UA predicted CAC progression (odds ratio 1.30 [95% CI 1.07-1.58], P=0.007) independent of conventional cardiovascular risk factors including diabetes and the presence of metabolic syndrome.
Conclusions: Serum UA levels predict the progression of coronary atherosclerosis and may be useful in identifying who is at risk for vascular disease in the absence of significant chronic kidney disease.
