The growing number of heart failure (HF) patients is becoming an important issue in cardiology. B-type natriuretic peptide (BNP) is a recognized marker of HF, including in patients with preserved systolic function. The TEI index is an indicator of left ventricular function. The aim of the study was to evaluate the relationship between BNP serum level, TEI index and the degree of diastolic dysfunction in patients with HF symptoms and preserved systolic function.
