title: Usefulness of parathyroid hormone as a predictor of heart failure with preserved ejection fraction.
abstract: OBJECTIVE
  To investigate the relation between parathyroid hormone (PTH) and heart failure with preserved ejection fraction (HF-PEF) in outpatients.
  
  
  METHODS
  One hundred consecutive patients who had preserved left ventricular (LV) ejection fraction and heart failure (HF) symptoms, were enrolled. Echocardiography, assessing the diastolic functions was performed. Blood samples were collected for intact PTH and brain natriuretic peptide (BNP).
  
  
  RESULTS
  Significant correlations between PTH level and predictors of advanced HF-PEF were found (p < 0.05). PTH level and left atrium diameter were found to be independent predictors of DHF.
  
  
  CONCLUSIONS
  Measurement of serum PTH provides complementary information for the diagnosis and prognosis of HF-PEF.
