Objectives: To evaluate the admission neutrophil-to-lymphocyte ratio (NLR) for risk stratification for in-hospital outcomes and complications in non-ST-elevation acute coronary syndrome (non-ST-ACS) patients. Methods: We recruited consecutive patients with non-ST-ACS. The NLR was obtained and stratified as low, intermediate, and high-risk based on6.0, respectively. The new ST-T changes, arrhythmias, contrast-induced nephropathy (CIN), and mortality were recorded. Results: Median NLR was 3 [2.1-5.3] for 346 patients with 19.9% and 30.6% in high- and intermediate-risk group. New ST-T changes were observed in 3.5%(12) out of which 8, 3, and 1 patient in low, intermediate, and high-risk group (p=0.424), respectively. Arrhythmias were observed in 5.8%(20) with 7, 5, and 8 patients in low, intermediate, and high-risk group (p=0.067), respectively. CIN was observed in 4.9%(17) with 5, 5, and 7 in low, intermediate, and high-risk group (p=0.064), respectively. In-hospital mortality was recorded in 1.4%(5) with 2 and 3 patients in high and low-risk group (p=0.260), respectively. Conclusion: A significant number of non-ST-ACS patients fall in the high-risk category of NLR. Although, the association between NLR and in-hospital mortality and adverse events was not statistically significant but relatively higher rates of events were observed in high risk group.
