Abstract

Objective: To assess the relationship between neutrophil-lymphocytes ratio (NLR) at admission and patient outcome over a period of six month in subjects with acute coronary syndrome (ACS).

Methods: A total of 435 consecutive patients presenting with ACS were enrolled and 400 patients completed the study. Patients were categorized into 2 groups: the NLR group 1 (NLR≤5.25; n=265, 66.25%) and the NLR group 2 (NLR>5.25; n=135, 33.75%). The primary outcomes were in-hospital and 6 months mortality.

Results: Forty-seven (11.8%) patients died during 6 months follow up. Higher mortality was seen in NLR group 2 (42/135, 34.1%) compared to NLR group 1 (5/265, 1.9%) with p value <0.001.

Conclusion: Our study suggest that elevated NLR (>5.25) is independently associated with higher all-cause mortality rate up to 6 months period irrespective of ACS type.

Keywords: Acute coronary syndrome (ACS); Mortality; Neutrophil–lymphocytes ratio (NLR).
