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.
Conclusion: Measurement of serum PTH provides complementary information for the diagnosis and prognosis of HF-PEF.
