About this trial

Most patients who receive hemodialysis treatments have excess fluid in their body that has slowly built up over the course of kidney disease. This extra fluid is the main cause of high blood pressure in dialysis and leads to stress on the heart and lungs.that causes debilitating symptoms and frequent hospitalizations.

This trial will test whether a focused program of 4 or 8 weeks of extra ultrafiltration treatments can remove most of this extra fluid. We believe that getting rid of large amounts of extra fluid will result in sustained improvements in blood pressure and symptoms. Ultrafiltration is a gentler type of dialysis that removes fluid but does not clean the blood.

Trial outcomes

Primary outcomes

1

24-hour continuous ambulatory blood pressure

Blood pressure measured continously for a 24-hour period by wearing a blood pressure cuff on the upper arm.

Time frame
Measurement performed at baseline compared to measurement performed at 24 weeks.
2

Symptoms of congestion.

Change in sypmtoms of congestion caused by fluid overload which we will access by using the Kidney-modified Kansas City Cardiomyopathy Questionnaire.

Time frame
Questionnaire taken at Baseline compared the the questionnaire taken at 24 weeks.
