SUMMARY OBJECTIVE Inflammation-related markers provide diagnostic and prognostic information for coronary artery disease and acute coronary syndrome. We aimed to compare neutrophil count and neutrophil/lymphocyte ratio (NLR) in acute coronary syndrome patients with coronary collateral development in our study. METHODS A total of 426 patients (102 unstable angina pectoris (USAP), 223 non-ST-elevation myocardial infarction (non-STEMI), 103 ST-elevation myocardial infarction (STEMI) were compared regarding hemoglobin, platelet, lymphocyte, neutrophil count, and NLR. RESULTS Neutrophil count and NLR were significantly lower in USAP patients and higher in STEMI patients; 5.14± 1.79 vs. 7.21± 3.05 vs. 9.93±4.67 and 2.92±2.39 vs. 5.19±4.80 vs. 7.93±6.38, p <0.001. Other parameters, i.e., hemoglobin, platelet, and lymphocyte count, were not significantly different between the groups. CONCLUSIONS In our study, it was concluded that there may be a statistically significant difference in the number of neutrophil counts and NLR among the types of acute coronary syndromes with coronary collateral development.

Several inflammatory biomarkers have been implicated in the pathogenesis of acute coronary syndromes. The present study aims to determine the prognostic value of neutrophil lymphocyte ratio (NLR) to predict the immediate outcomes in patients with acute ST elevation myocardial infarction and if any correlation exists between NLR and TIMI risk score. A review of articles published in Pubmed database on the prognostic importance of neutrophil lymphocyte ratio in determining major adverse cardiac events (MACE) such as arrhythmias, cardiogenic shock and in hospital mortality was done. NLR was found to be a reliable prognostic tool to assess the immediate outcome in ST elevation myocardial infarction (STEMI) patients.

Background: The aim of this study is to investigate the role of the neutrophil-lymphocyte ratio (NLR) in the differential diagnosis of non-ST elevation myocardial infarction (NSTEMI) and unstable angina pectoris (USAP). Material and Method: Patients who had been admitted to the emergency ward with complaints of chest pain and who were diagnosed with USAP and NSTEMI in further examination were retrospectively included in this study. The NLR level was measured for each patient both at the times of application and of discharge. The NLR was calculated by dividing the neutrophil count by the lymphocyte count. Results: WBC (8107.38±1405.5 vs 7452.46±1427.9, p: 0.020), neutrophil (5620 vs 4300, p: 0.001), and NLR (3.86 vs 2.14, p: 0.001) values were higher, whereas the lymphocyte value (1505 vs 2100, p: 0.001) was lower in the NSTEMI versus the USAP group. According to the multivariable logistic regression analysis that was done, NLR appeared to be an independent predictor of NSTEMI. The predictive value of NLR for NSTEMI diagnosis was >3.22 with 61.9% sensitivity and 86.96% specificity (74.3% positive predictive, 78.9% negative predictive) (AUC: 0.761; p< 0.001). Conclusion: As a cheap inexpensive and easy-to-calculate index that can be applied in every medical establishment within the first 20 minutes of application, it is possible to state that NLR is a good marker in distinguishing NSTEMI from USAP patients.
