BACKGROUND: An early prediction of prognosis in pulmonary embolism (PE) is a crucial clinical entity. The aim of the study is to investigate whether growth differentiation factor-15 (GDF-15) or N-terminal pro-brain natriuretic peptide levels (NT-proBNP) can better predict the 30 day overall mortality in patients with normotensive acute PE. METHODS: Patients with a high clinical probability of PE, or with low/intermediate probability and a positive D-dimer test, underwent contrast-enhanced computed tomography and ventilation/perfusion lung scan. Simplified pulmonary embolism severity index, the presence of echocardiographic right ventricular dysfunction, and ROC curve analysis by calculated cut-off value of serum GDF-15 and NT-proBNP levels were evaluated for each individual of study population. RESULTS: The serum levels of GDF-15 and NT-proBNP were found to be significantly higher in patients with PE compared with controls (p < 0.0001). In this study, GDF-15 provided better results compared to NT-proBNP in predicting the short-term or 30 day mortality (p = 0.046 and p = 0.418, respectively). Serum GDF-15 with a cut-off value of > 2943 pg/mL yielded a 75% sensitivity, 68.7% specificity, 91.6% negative predictive value, and 90% accuracy for predicting 30 day overall mortality. The results of these tests were found as 62.5%, 40.6%, 81.2%, and 40% for NT-proBNP (with the cut-off value of > 1409 pg/mL), respectively. CONCLUSIONS: High serum GDF-15 levels may provide better information than NT-proBNP for early death in the subjects with normotensive PE and these patients should be closely followed up.
