Background: There are few studies evaluating the prognostic value of lactate dehydrogenase (LDH) in patients with pulmonary embolism (PE). We analyzed possible power of serum LDH level 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 were 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. Conclusions: In patients with pulmonary embolism, LDH can be a good prognostic marker for predicting in-hospital death.
