Özet

BackgroundStroke therapy options have focused on limiting the infarct volume. Neutrophil to lymphocyte ratio (NLR) can be valuable to detect the patients that required intensive treatment at early stage by predicting infarct volume. The aim of this study is to evaluate the relationship between NLR and infarct volume according to the stroke territory, and to determine the prognostic value of NLR for predicting 3-month mortality in acute ischemic stroke (AIS) patients.MethodsA total of 107 patients with AIS were enrolled and followed up 3months in terms of mortality. Study population was divided into two groups according to the stroke territory: anterior circulating stroke (ACS) and posterior circulating stroke (PCS). All patients underwent magnetic resonance imaging. The complete blood count and venous blood samples were obtained from the patients on admission to the emergency department.ResultsThere were no difference between ACS and PCS groups regarding baseline characteristics and co-morbid diseases. Also, C-reactive protein and NLR were similar between two groups. In correlation analyses, infarct volume was significantly correlated with CRP and NLR in ACS (r=0.350, p=0.001 and r=0.482, p0.001, respectively), but not correlated with infarct volume in PCS. Also, NLR was correlated with NIHHS in only ACS group (r=0.326, p=0.002). Multivariate analysis showed that NLR was the only independent predictor of 3-month mortality (OR 1.186, 95% CI 1.032-1.363, p=0.016).ConclusionNLR is significantly correlated with ACS infarct volume, but not with PCS infarct volume in AIS. Also, NLR was an independent predictor of 3-month mortality in AIS patient.
