INTRODUCTION: According to current ESC guidelines not only hemodynamic parameters, but also indices of right ventricular dysfunction such as NT-proBNP have a significant prognostic value in acute pulmonary embolism (PE). MR-proADM is a significant predictor of short-term mortality in acute heart failure and adds prognostic value to NT-proBNP. We hypothesized that plasma MR-proADM is elevated in acute PE, correlates with the severity of PE and has prognostic value. We also compared prognostic values of MR-proADM and NT-proBNP for the prediction of early mortality in acute PE.
MATERIAL & METHODS: We studied 98 patients (51F/47M, 59.6±18.4yr) with acute PE. On admission blood samples were collected for MR-proADM and NT-proBNP.
RESULTS: MR-proADM reflected the severity of acute PE: 0.734nmol/L in low-risk acute PE (0.384-1.342), 0.995nmol/L in intermediate-risk acute PE (0.394-7.499) and 2.062nmol/L in high-risk acute PE (0.447-3.098), p<0.001. MR-proADM was higher in non-survivors than in survivors 2.123nmol/L (1.543-4.220), vs. 0.910nmol/L (0.384-7.449), p=0.0003. The AUC of MR-proADM and NT-proBNP ROC curves for predicting all-cause mortality were 0.935 (95% CI 0.861-0.977) and 0.844 (95% CI 0.749-0. 913), respectively. In univariable analysis NT-proBNP and MR-proADM were significant predictors of all-cause mortality HR 1.00 (95% CI 1.000-1.0002, p=0.029) and 1.65 (95% CI 1.214 - 2.249, p=0.015). However, in multivariate analysis, MR-proADM but not NT-proBNP was a significant predictor of all-cause mortality.
CONCLUSION: NT-proBNP and MR-proADM are of similar predictive value in the assessment of outcome in acute PE, however MR-proADM seems to be superior in predicting all-cause mortality.
