<bold>Aims</bold>: This study assessed the effects of individualized dialysis sodium prescription on changes of echo-cardiography in hemodialysis (HD) patients.
<bold>Methods</bold>: 77 chronic hemodialysis patients were analysed. In the first phase all patients underwent dialysis with standard dialysate sodium of 138 mmol/L followed by the second phase where dialysis was performed with individualized dialysate sodium concentration according to average pre HD serum sodium concentration. After the first phase, the subjects were divided into 3 groups: normotensive, hypertensive and hypotensive based on the average pre-HD systolic BP during the first phase. In all patients echocardiography was performed at the end of the first and second phase.
<bold>Results</bold>: Patients had no statistical significant change in blood pressure compared with standard dialysate sodium, only statistical significant change in interdialytic weight gain (IDWG). By dividing the patients, sodium individualization resulted in significantly lower blood pressure and IDWG (p=0.018) in hyper-tensive patients, whereas normotensive patients showed only significant decrease in IDWG (p=0,004). Hypertensive patients had significant highest sodium gradient compared to other patients (p&lt;0.05), followed by significant increase of 0,6% IDWG confirmed with univariate regression analysis. In all patients, echocardiography analysis showed an increase of 2.04 mm of LVDD by increasing the sodium gradient for 1 mmol/L and significantly increased LVM of 35.69 gr by 1 kg increase in IDWG.
<bold>Conclusions</bold>: A reduction of the dialysate sodium concentration based on the pre HD serum sodium level of the patient, reduced the SBP, DBP and IDWG and decreased the volume overload upon the heart and consequently heart hypertrophy assessed by echocardiography.

Aims: This study assessed the effects of individualized dialysis sodium prescription on changes of echo-cardiography in hemodialysis (HD) patients.
Methods: 77 chronic hemodialysis patients were analysed. In the first phase all patients underwent dialysis with standard dialysate sodium of 138 mmol/L followed by the second phase where dialysis was performed with individualized dialysate sodium concentration according to average pre HD serum sodium concentration. After the first phase, the subjects were divided into 3 groups: normotensive, hypertensive and hypotensive based on the average pre-HD systolic BP during the first phase. In all patients echocardiography was performed at the end of the first and second phase.
Results: Patients had no statistical significant change in blood pressure compared with standard dialysate sodium, only statistical significant change in interdialytic weight gain (IDWG). By dividing the patients, sodium individualization resulted in significantly lower blood pressure and IDWG (p=0.018) in hyper-tensive patients, whereas normotensive patients showed only significant decrease in IDWG (p=0,004).

In all patients, echocardiography analysis showed an increase of 2.04 mm of LVDD by increasing the sodium gradient for 1 mmol/L and significantly increased LVM of 35.69 gr by 1 kg increase in IDWG.
Conclusions: A reduction of the dialysate sodium concentration based on the pre HD serum sodium level of the patient, reduced the SBP, DBP and IDWG and decreased the volume overload upon the heart and consequently heart hypertrophy assessed by echocardiography.
