The Association between Serum Lactate Dehydrogenase Level and In-hospital Death due to Pulmonary Embolism

Background: Few studies are evaluating the prognostic value of lactate dehydrogenase (LDH) in patients with pulmonary embolism (PE). We analyzed the possible power of serum LDH levels to predict in-hospital mortality.Methods: In this cross-sectional study 217 patients with confirmed PE diagnosis with CT angiography and available serum LDH level at first 24-hours upon admission were included.Results: The mean age of patients was 63.04±16.81 years old, 23 patients (10.6%) died during hospitalization. Multivariate analysis showed that only LDH, WBC were independent predictors of in-hospital mortality, however, this association was not significant.Conclusion: LDH can be a good prognostic marker for predicting in-hospital death in patients with pulmonary embolism.
