Abstract
IntroductionNeutrophil to lymphocyte ratio (NLR) was revaled to have a close relation with atherosclerotic cardiovascular disease. The relationship between NLR and culprit plaque localization has never been studied.Aim of the studyTo evaluate the association between NLR and unstable plaque localization of left anterior descending artery (LAD) in anterior miyocardial infarction patients.Material and methodsPatients admitted to our hospital with acute anterior STEMI were included. Fifhy-eight patients who have single-vessel disease at LAD and their hematological parameters were analyzed retrospectively. Proximal segment of LAD lesions were groupped as Group I and mid segment of the LAD lesion groupped as Group II. The groups were compared according to their NLR and other parameters.ResultsBetween group I (n = 41, mean age 52.5 ±12.7) and group II (n = 17, mean ages 52.0 ±10.8); NLR, were significantly higher in group I compared to the group II (6.9 ±5.6 vs. 3.3 ±2.0, p = 0.01). In group I, left ventricular ejection fraction (LVEF) was significantly lower (p = 0.02). In correlation analyzes, NLR was positively correlated with CK MB (r = 0.32, p = 0.01) and negatively correlated with LVEF (r = –0.28, p = 0.03).ConclusionsThe present study demonstrated that anterior myocardial infarction patients with high NLR had a greater possibility having proximal culprit lesion on the LAD. Therefore NLR can be used as a useful tool to culprit plaque localization in patients with acute miyocardial infarction patients.
