Left ventricular diastolic function in patients on hemodialysis.
Additional Document Info
Previous studies have shown that the assessment of Doppler mitral flow velocity (DMFV) curves can be used to predict prognosis owing to left ventricular (LV) diastolic dysfunction in certain specific diseases. Our aim was to study whether the prognostic value of DMFV curves is affected by the many end-stage renal disease factors, such as chronic uremia and long-term hemodialysis (HD), which cause LV diastolic dysfunction and death.Retrospective echo Doppler studies obtained 10 to 12 hours after HD in 90 patients (52 males; mean age, 56 years) were analyzed to determine changes in deceleration time (DT) of the early mitral filling wave (E) and the ratio of E to the atrial velocity (A). The study findings (n = 83) showed 2 groups of DT: long DT (DT > 240 milliseconds) and normal/short DT (DT
