Cardiovascular Diseases Clinical Trial
Official title:
HaemoDialysis Interventions to REduce Multi-Organ Dysfunction and Effect on Quality of Life (HD-REMODEL) Assessed by MRI Scanning
The purpose of this study is to characterise in detail cardiac, cerebral and renal structure, function and perfusion in patients on haemodialysis (HD) using magnetic imaging techniques. The effects of a standard prescription haemodialysis (dialysate temperature 37 C) will be compared to a thermocontrolled (or isothermic) haemodialysis prescription to ascertain if thermocontrolled HD provides a protective effect on organ perfusion and circulatory stress when compared to conventional haemodialysis. The BTM (blood temperature monitor, Fresenius) offers a way to overcome this to regulate thermal balance during dialysis and achieve a neutral thermal balance (isothermic) over the dialysis session. Other dialysis parameters will be standardised between treatment arms using blood volume monitoring (BVM) and clinical assessments.
The purpose of this study is to characterise in detail cardiac, cerebral and renal structure, function and perfusion in patients on haemodialysis (HD) using magnetic imaging techniques. The Primary objectives are to investigate the difference in cardiac perfusion, structure and function between standard HD and thermocontrolled HD using magnetic imaging techniques, to observe the the changes in renal perfusion and oxygenation within one dialysis session and the changes to cerebral perfusion within one dialysis session. The secondary objectives are to investigate the difference in cerebral perfusion, structure, oedema and function between standard HD and thermocontrolled HD, the difference in renal perfusion and oxygenation between standard HD and thermocontrolled HD and the differences in visual acuity and cognitive assessment across a dialysis session and over a dialysis treatment course. ;
