Uric acid is predictive of cardiovascular mortality and sudden cardiac death in subjects referred for coronary angiography.
G Silbernagel, MM Hoffmann... - Nutrition, metabolism, ..., 2011 - BACKGROUND AND AIMS: High serum uric acid (SUA) is suggested to be causally involved
in the pathogenesis of vascular disease. The present study aimed to investigate whether SUA
independently predicts all-cause mortality, cardiovascular mortality and sudden cardiac ...
We studied participants of the L Udwigshafen R Isk and Cardiovascular health (LURIC) study. A total of 3245 individuals were included in the analysis. There was a follow-up for all-cause mortality, cardiovascular mortality, and sudden cardiac death with a mean (±standard deviation) duration of 7.3 (±2.3) years. Sex-specific quartiles of SUA were established and multivariate statistical models were used. A total of 730 deaths occurred during the follow-up. Among these, 473 (64.8%) were accounted for by cardiovascular diseases. Sudden cardiac death occurred in 184 (25.2%) cases. Adjusting for sex and age subjects in the fourth SUA quartile had increased all-cause (hazard ratio (HR) = 1.68, p < 0.001) and cardiovascular (HR = 2.00, p < 0.001) mortality compared to individuals in the first quartile. Furthermore, high SUA was a risk factor for sudden cardiac death (HR = 2.27, p < 0.001). These associations remained significant including cardiovascular risk factors and the severity of coronary atherosclerosis as covariates in the models. After additional adjustment for medication use statistical significance for the association between the SUA quartiles and all-cause mortality disappeared.
