Background Risk stratification among patients with coronary artery disease ( CAD ) is of considerable interest due to the potential to guide secondary preventive therapies. Thus, we evaluated the predictive value of soluble urokinase‐type plasminogen activator receptor (su PAR ) levels for cardiovascular mortality and nonfatal myocardial infarction in patients with CAD . Methods and Results Plasma levels of su PAR were measured in a cohort of 1703 patients with documented CAD as evidenced by coronary angiography—including 626 patients with acute coronary syndrome and 1077 patients with stable angina pectoris. Cardiovascular death and/or nonfatal myocardial infarction were defined as main outcome measures. During a median follow‐up of 3.5 years, su PAR levels reliably predicted cardiovascular death or myocardial infarction in CAD , evidenced by survival curves stratified for tertiles of su PAR levels. In Cox regression analyses, the hazard ratio for the prediction of cardiovascular death and/or myocardial infarction was 2.19 ( P <0.001) in the overall cohort and 2.56 in the acute coronary syndrome cohort ( P <0.001). Even after adjustment for common cardiovascular risk factors, renal function and the biomarkers C‐reactive protein, N‐terminal pro‐B‐type natriuretic peptide and high‐sensitivity troponin I su PAR still enabled a reliable prediction of cardiovascular death or myocardial infarction with a hazard ratio of 1.61 ( P =0.022) in the overall cohort and 2.22 ( P =0.005) in the acute coronary syndrome cohort. Conclusions Su PAR has a strong and independent prognostic value in secondary prevention settings, and thereby might represent a valuable biomarker for risk estimation in CAD .
