BACKGROUND: Neutrophil-to-lymphocyte ratio (NLR) has been found to be a good predictor of future adverse cardiovascular outcomes in @entity1 with @entity583 ( @entity583 ). Changes in the QRS terminal portion have also been associated with adverse outcomes following @entity583 . OBJECTIVE: To investigate the relationship between ECG @entity63 grade and NLR in @entity1 presenting with @entity583 , in order to determine additional conventional risk factors for early risk stratification. METHODS: @entity1 with @entity583 were investigated. The grade of @entity63 was analyzed from the ECG performed on admission. White blood cells and subtypes were measured as part of the automated complete blood count (CBC) analysis. @entity1 were classified into two groups according to the @entity63 grade presented on the admission ECG, as grade 2 @entity63 ( @entity68511 ) and grade 3 @entity63 (G3I). RESULTS: @entity1 with G3I had significantly lower mean left ventricular ejection fraction than those in G2I (44.58    7.23 vs. 48.44    7.61, p = 0.001). As expected, in-hospital mortality rate increased proportionally with the increase in @entity63 grade (p = 0.036). There were significant differences in percentage of lymphocytes (p = 0.010) and percentage of neutrophils (p = 0.004), and therefore, NLR was significantly different between G2I and G3I @entity1 (p < 0.001). Multivariate logistic regression analysis revealed that only NLR was the independent variable with a significant effect on ECG @entity63 grade (odds ratio = 1.254, 95% confidence interval 1.120-1.403, p < 0.001). CONCLUSION: We found an association between G3I and elevated NLR in @entity1 with @entity583 . We believe that such an association might provide an additional prognostic value for risk stratification in @entity1 with @entity583 when combined with standardized risk scores.
