This study sought to investigate the clinical correlates and prognostic roles of urokinase-type plasminogen activator receptor (uPAR) on circulating monocytes in patients with coronary artery disease (CAD).


263 angina patients were included in this study. The percentage of uPAR expressing monocytes (PUEM) and the mean fluorescence intensity (MFI) index of uPAR were measured using flow cytometry. Patient follow-up was on average 604 days. Major adverse cardiac events (MACE) were defined as a composite of cardiac death, reinfarction, acute heart failure and hospitalization for revascularization.


The PUEM and MFI index levels were significantly more elevated in acute coronary syndrome patients than in stable ones. uPAR expressions on circulating monocytes at admission were correlated to inflammatory biomarkers and myocardial necrosis. Logistic regression analysis revealed that PUEM ≥15% (OR 21.96, 95% CI 7.31-65.98, p < 0.001) and uPAR MFI index ≥3.00 (OR 3.54, 95% CI 1.18-10.59, p = 0.024) were independent determinants of clinical instability in patients with CAD. When followed up, a high PUEM level at admission was an independent prognostic parameter for long-term MACE (HR 3.99, 95% CI 1.31-12.11, p = 0.015).


uPAR expression on circulating monocytes is associated with clinical instability and myocardial necrosis and independently predicts the risk of MACE in patients with CAD.
