We sought to determine the prognostic value of neutrophil to lymphocyte ratio (NLR) in non-ST elevation myocardial infarction (NSTEMI) and unstable angina pectoris (UAP). A total of 308 (mean age 59.22 +/- 11.93) patients with NSTEMI and UAP were prospectively evaluated. The study population was divided into tertiles based on admission NLR values. The patients were followed for clinical outcomes for up to 3 years after discharge. In the Kaplan-Meier survival analysis, 3-year mortality was 21.6% in patients with high NLR versus 3% in the low-NLR group (P < .001). In a receiver-operating characteristic curve analysis, an NLR value of 3.04 was identified as an effective cut point in NSTEMI and UAP of a 3-year cardiovascular mortality (area under curve [AUC] = 0.86, 95% confidence interval [CI] 0.8-0.92). An NLR value > 3.04 yielded a sensitivity of 79% and specificity of 71%. Admission NLR is the strong and independent predictor of a 3-year cardiovascular mortality in patients with NSTEMI and UAP.
