| Popis: | Aim. To study the diagnostic value of the left atrial stiffness index (LASI) of heart failure with preserved ejection fraction (HFpEF) depending assessed by transthoracic echocardiography (TTE) in the diagnosis on diastolic stress test (DST) results.Material and methods. DST was performed in cases of insufficient criteria for increased left ventricular filling pressure assessed by TTE. One hundred patients were examined (52,0% men, 66,1±5,4 years). Patients with a ratio of early transmitral flow velocity to early diastolic mitral annulus velocity (E/e') ratio >15 in DST were included in group I (n=45), patients with E/e' 0,38 has the greatest ability to detect HFpEF among the possible pretest diagnostic methods. |
