Abstract
Background: The research explores the predictive efficacy of the neutrophil-to-lymphocyte ratio (NLR) in conjunction with the Global Registry of Acute Coronary Events (GRACEs) score for inhospital major adverse cardiovascular events (MACEs) among acute ST-segment elevation myocardial infarction (STEMI) subjects with primary percutaneous coronary intervention (PCI) history.
Materials and methods: Patients were categorized into MACE (n = 58) and non-MACE cohorts (n = 184) based on MACE occurrence events during hospitalization. The predictive value of the NLR, GRACE score, and their combination for inhospital MACE events in STEMI subjects was assessed by the receiver operating characteristic curve (ROC).
Results: NLR (8.99 [5.06, 12.01] vs. 5.15 [3.13, 7.66]) and GRACE scores (159.62 ± 43.39 vs. 116.96 ± 28.15) within MACE group notably surpassed the non-MACE group (P < 0.05). ROC curve analysis demonstrated that the area under the curve (AUC) for NLR in forecasting inhospital MACE events was 0. 72 (95% confidence interval [CI]: 0.645-0.795), with 0.655 sensitivity and 0.723 specificity, and optimal cutoff value as 7.01. The AUC for the GRACE score was 0.791 (95% CI: 0.717-0.865), with 0.862 sensitivity and 0.598 specificity, and the optimal cutoff value was 121.5. The combined AUC of NLR and GRACE score was 0.814 (95% CI: 0.745-0.884), with 0.707 sensitivity and 0.837 specificity.
Conclusion: Both NLR and GRACE score independently predict inhospital MACE events in STEMI patients post-PCI. Integration of the NLR and GRACE score enhances accuracy in forecasting inhospital MACE event occurrences.
