- Circulating neutrophil gelatinase-associated lipocalin (NGAL) concentration increases in cardiovascular disease, but the long-term prognostic value of NGAL concentration has not been evaluated in acute coronary syndrome (ACS). We examined the association between NGAL concentration and prognosis in patients with ACS after non-ST-elevation myocardial infarction (NSTEMI) or STEMI.NGAL concentration was measured in blood from 1121 consecutive ACS patients (30% women, mean age 65years) on the first morning after admission. After adjustment for 14 variables, NGAL concentration predicted long-term (median 167months) mortality (hazard ratio [HR] 1.33, 95% confidence interval [CI] 1.10-1.61, P=0.003) for quartile (q) 4 of NGAL concentration. NGAL concentrations also predicted long-term mortality (HR=1.63, 95% CI 1.31-2.03, P<0.001, N=741) when adjusting for Global Registry of Acute Coronary Events (GRACE) score, left ventricular ejection fraction (LVEF), and pro-B-type natriuretic peptide (proBNP) and C-reactive protein (CRP) concentrations. With these adjustments, NGAL concentration predicted long-term mortality in NSTEMI patients (HR=2.02, 95% CI 1.50-2.72, P<0.001) but not in STEMI patients (HR=1.32, 95% CI 0.95-1.83, P=0.100). In all patients, the combination of NGAL concentration and GRACE score yielded an HR of 5.56 (95% CI 4.37-7.06, P<0.001) for q4/q4 for both variables.NGAL concentration in ACS is associated with long-term prognosis after adjustment for clinical confounders. Measuring circulating NGAL concentration may help to identify patients-particularly those with NSTEMI-needing closer follow-up after ACS.
