title: [Clinical value of brain natriuretic peptide level in patients with atrial fibrillation].
abstract: PURPOSE of this investigation was to study correlation between brain natriuretic peptide (BNP), extent of cardiac abnormalities, and six minute walk test (6-MWT) in order to asses diagnostic value of BNP in patients with trial fibrillation (F), heart failure (HF) and preserved systolic function.
  
  
  METHODS
  Sixty five patients with history of hypertension, permanent F, and shortness of breath in absence of signs of congestive hemodynamics were included into this study.
  
  
  RESULTS
  Concentration of BNP in serum n the day of inclusion was significantly inversely related to results of 6-MWT, and positively related to left atrial dilation, to hospitalizations due to cardiovascular causes.
  
  
  CONCLUSIONS
  Measurement of BNP concentration in patients with AF allows to diagnose HF at early stages and to predict cardiovascular complications.
