The effect of neutrophil/lymphocyte ratio on 1-year mortality in pulmonary embolism diagnosed patients

Background: Pulmonary embolism (PE) is one of the major causes of mortality, morbidity and hospitalizations. We aimed to investigate the effect of neutrophil/lymphocyte ratio (NLR) on 1-year mortality.

Material and Methods: Among the patients, were referred to the emergency department of our hospital within 1-year who underwent computed tomography pulmonary angiography (CTPA), patients who were interpreted as PE after CTPA were included in the study.

Results: The optimal NLR cutoff value for the power in predict 1-year mortality was determined as 4.74 with ROC analysis. The NLR cutoff value of 4.74 had sensitivity of 61%, specificity of 75%. There were statistically significant differences between groups in terms of NLR on 1-year mortality and mortality in patients with a NLR greater than 4.74 was statistically significant higher than in patients with a NLR of 4.74 or less.

Conclusion: We believe that NLR can be used in evaluating 1-year mortality of pulmonary embolism.
