Objective-Inflammation plays a key role in atherosclerosis. We hypothesized that novel inflammatory markers may predict the risk of coronary heart disease (CHD). Approach and Results-We investigated the association of 16 inflammatory biomarkers with the risk of CHD in a random subset of 839 CHD-free individuals in a prospective population-based cohort study. A Bonferroni corrected P value of 3.1x10(-3) was used as a threshold of statistical significance. The mean age at baseline was 72.8 years. During a median follow-up of 10.6 years, 99 cases of incident CHD were observed. Among all inflammatory biomarkers, neutrophil-derived human s100a12 (extracellular newly identified receptor for advanced glycation end-products binding protein [ EN-RAGE]) showed the strongest association with the risk of CHD (P value 2.0x10(-3)). After multivariable adjustment for established cardiovascular risk factors, each standard deviation increase in the natural log-transformed EN-RAGE was associated with 30% higher risk of incident CHD (hazard ratio, 1.30; 95% confidence interval, 1.06-1.59). Further adjustment for previously studied inflammatory markers did not attenuate the association. Excluding individuals with prevalent type 2 diabetes mellitus, impaired kidney function, or individuals using antihypertensive medication did not change the effect estimates. Cause-specific hazard ratios suggested a stronger association between EN-RAGE and CHD mortality compared with stable CHD. Conclusions-Our results highlight EN-RAGE as an inflammatory marker for future CHD in a general population, beyond traditional CHD risk factors and inflammatory markers.
