Background. Changes in the circulating volume associated with hemodialysis (HD) resulted in alternations of left ventricular (LV) filling. However, previous studies offered conflicting findings. This study thus evaluated the impact of HD on LV diastolic filling indices and hemodynamics. Materials and Methods. Forty patients with end-stage renal disease were studied by Doppler echocardiography immediately before and after HD. The cardiac size, volume and mass were determined by M-mode and two-dimensional echocardiography. LV diastolic filling parameters and hemodynamics were assessed from mitral inflow using Doppler echocardiography. Results. Left atrial and LV dimension, LV volume, and LV mass decreased significantly after HD (p<0.001). Cardiac output declined from 5.74±1.37 to 4.98±1.27 L/min (p<0.001), whereas, the ejection fraction remained unchanged. HD elicited marked changes in the early diastolic E (95.1±20.5 to 70.3±18.2 cm/s, p<0.001) and late atrial filling A velocities (104.3±20.9 to 88.9±16.9 cm/s, p<0.001). In addition, correction of the deceleration time of E and isovolumic relaxation time prolonged significantly (p=0.011 and p<0.001, respectively). Conclusions. Findings in this study indicate that HD altering the loading condition significantly influenced the LV diastolic function and hemodynamics. Moreover, Doppler echocardiography provides an effective means of assessing the effects on LV diastolic filling and hemodynamics during HD.
