title: Neutrophil-lymphocyte ratio may predict in-hospital mortality in patients with acute type A aortic dissection.
abstract: BACKGROUND
  Inflammation has been reported to be associated with aortic dissection (AD), from the development to the prognosis of AD. In this study we aimed to find the role of the neutrophil-lymphocyte ratio (NLR) in the prediction of clinical events in patients with acute AD type A.
  
  
  METHODS
  The study comprised 37 patients who were hospitalized at our center between 2009 and 2013 with the diagnosis of acute AD type A.
  
  
  RESULTS
  The mean NLR was significantly higher in patients with pericardial effusion than those without effusion (15.6 ± 11.4 vs. 7.5 ± 4.8, p = 0.005). An NLR value > 8.51 yielded an area under the curve (AUC) value of 0.829 [95 % confidence interval (CI) 0.674-0.984, p = 0.004], which demonstrated a sensitivity of 77 % and specificity of 74 % for the prediction of mortality.
  
  
  CONCLUSIONS
  The novel inflammatory marker NLR could be used to predict pericardial effusion and in-hospital mortality in patients with acute AD type A.
