Relation of Neutrophil-to-Lymphocyte Ratio With GRACE Risk Score to In-Hospital Cardiac Events in Patients With ST-Segment Elevated Myocardial Infarction

In this study, we aimed to investigate the association of the neutrophil-to-lymphocyte ratio (NLR) with Global Registry of Acute Coronary Events (GRACE) risk score in patients with ST-segment elevated myocardial infarction (STEMI). We analyzed 101 consecutive patients with STEMI. Patients were divided into 3 groups by use of GRACE risk score. The association between NLR and GRACE risk score was assessed. The NLR showed a proportional increase correlated with GRACE risk score (P < .001). The occurrence of in-hospital cardiac death, reinfarction, or new-onset heart failure was significantly related to NLR at admission (P < .001). Likewise, NLR and GRACE risk score showed a significant positive correlation (r = .803, P < .001). In multivariate analysis, NLR resulted as a predictor of worse in-hospital outcomes independent of GRACE risk score. Our study suggests that the NLR is significantly associated with adverse in-hospital outcomes, independent of GRACE risk score in patients with STEMI.
