Background: The eotaxin family comprises three distinct peptides (eotaxin, eotaxin-2 and eotaxin-3) which have been implicated in eosinophilic inflammation. In vitro and clinical studies suggest that eotaxins could play a role in vascular inflammation, but no data are available on their prognostic significance in patients with angiographically documented coronary artery disease (CAD). Materials and methods: Baseline plasma samples were obtained from 1014 patients with documented CAD. We tested the predictive effect of markers of eosinophilic inflammation and C-reactive protein (CRP) on death from cardiovascular causes and nonfatal myocardial infarction over a 2.7-4.1-year follow-up period. Results: Unexpectedly, lower eotaxin-3 concentrations were observed in patients with adverse cardiovascular events, whereas both eotaxin and eotaxin-2 showed no association with risk. After adjustment for most potential confounders, patients in the upper-quartile of eotaxin-3 levels had a 0.42 hazard-ratio (95% CI, 0.29-0.61, P <0.001) for adverse events compared with subjects in the lower-quartile. The highest risk of future cardiovascular events was observed in subjects with combined elevation of CRP and reduction of eotaxin-3; 4.4 hazard-ratio (95% CI, 2.1-9.5, P <0.001). Importantly, receiver-operating-characteristic curves analysis suggested a superior prognostic value of eotaxin-3 compared with CRP for predicting cardiac events in patients with CAD. Conclusions: Low levels of eotaxin-3 are an independent predictor of future adverse cardiovascular events in patients with CAD and may be useful for risk stratification.
