title: Relationship between neutrophil to lymphocyte ratio and slow coronary flow.
abstract: OBJECTIVE
  We evaluated the relationship between neutrophil to lymphocyte ratio (NLR) and slow coronary flow (SCF).
  
  
  METHODS
  A total of 180 participants were recruited to the present study. Of all the participants, 82 patients were with SCF and 98 participants were with normal coronary arteries. Basal characteristics were recorded. Coronary flow was quantified by thrombolysis in myocardial infarction frame count.
  
  
  RESULTS
  Basal characteristics were similar between the 2 groups. The NLR was significantly higher in the SCF group when compared to the control group (2.3 ± 0.8 and 1.5 ± 0.4 respectively, P < .001). In multiple logistic regression analysis, NLR remained as the independent predictor of SCF (P < 0.001).
  
  
  CONCLUSIONS
  Our findings showed that NLR was significantly higher in the SCF group when compared to the control group with normal coronary arteries. We also showed that NLR was related to the presence of SCF rather than the extent of SCF. Besides these findings, we also showed the NLR as an independent predictor of SCF.
