Leukocyte count predicted the risk of first-time myocardial infarction and ischemic stroke. The aim of this study was to determine the role of elevated leukocyte count in non-diabetic patients admitted for acute first-ever ischemic stroke on clinical presentation and 3-year mortality. We studied 462 patients with acute first-ever ischemic stroke without diabetes mellitus or active infection at admission. Patients were classified into 2 groups according to their leukocyte count. A white blood cell (WBC) count ≥10,000/μL was defined as an elevated leukocyte count, otherwise as normal. Clinical presentation, risk factors for stroke, laboratory data, co-morbidities, and outcomes were recorded. 64 patients (13.9%) had elevated leukocytes. Multivariate logistic regression showed that an elevated platelet count was positively associated with the elevated leukocyte count, while a low serum sodium level was negatively associated with an elevated leukocyte count (P=0.008, P=0.003, respectively). An elevated leukocyte count was associated with a higher risk of a stroke in evolution (P=0.021). Multivariate Cox regression analysis revealed that an elevated leukocyte count is a significant predictor of 3-year mortality [P=0.010, HR=3.26 (1.33-7.98)]. In conclusion, higher leukocyte counts during the acute stroke stage are associated with increased risk of 3-year mortality in patients with acute, first-ever ischemic stroke.
