RESUMO
Background: NGAL serum concentration have predictive value for cardiovascular events and mortality in patients with acute coronary syndrome (ACS). Objectives: Assessed the all-cause mortarlity prognosis value of serum neutrophil gelatinase-associated lipocalin (NGAL), combination with N-terminal pro B-type natriuretic peptide (NT-proBNP), and hsTnT, and GRACE score in patients with ACS. Materials and methods: We conducted a cross-sectional analysis study used in this study in 58 patients with ACS. Serum NGAL, NT-proBNP, hs-TnT concentration and GRACE score associated with death events (after 3 months of follow-up) were assessed by receiver operating characteristic (ROC) curve. Results: High performance in predicting mortality of NGAL with a cut-off value of 154.55 ng/mL (AUC, 95% CI = 0.96, 0.90 - 1.0; p = 0.001), GRACE score with 140.50 scores (AUC, 95% CI = 0.76, 0.57 - 0.96; p = 0.051). Combination of NTproBNP plus NGAL indicated with the highest value (AUC, 95% CI = 0.96, 0.91 - 1.0; Se = 80.0; Sp = 92.5; p = 0.001). The relative risk assessment indicated a high value in mortality prediction of NGAL with a cut-off value of 154.55 (OR, 95% CI = 49.0, 4.3 - 549.2; p < 0.001), and GRACE score with 140.50 scores (OR, 95% CI = 11.1, 1.1 - 108.4; p = 0.013). Conclusion: NGAL can be employed as a biomarker for the early prediction of mortality events in individuals with ACS. The combination of NGAL, NT-proBNP, hsTnT, and GRACE score showed the higher outcome but not worth mentioning.
