title: ANP, BNP and D-dimer predict right ventricular dysfunction in patients with acute pulmonary embolism.
abstract: BACKGROUND
  The aim of this study was to predict right ventricular dysfunction (RVD) using plasma concentration of D-dimer, pro-atrial natriuretic peptide (pro-ANP), brain natriuretic peptide (BNP), endothelin-1 (ET-1) and cardiac troponin I (TNI) in patients with pulmonary embolism (PE).
  
  
  METHODS
  Patients suspected of PE had a ventilation/perfusion-single-photon emission-tomography (V/Q-SPECT), pulmonary multidetector computer tomography (MDCT) angiography, blood samples and ECG-gated cardiac CT performed the same day.
  
  
  RESULTS
  Pro-ANP, BNP and D-dimer are associated with significantly elevated levels in PE patients with RVD. ROC curves demonstrated that D-dimer, pro-ANP and BNP were accurate for detection of RVD.
  
  
  CONCLUSIONS
  Because measurements of cardiac biomarkers are inexpensive and easily obtained they may prove useful in the clinical diagnosis of RVD. However because of the small sample size, the results need to be confirmed in larger studies.
