ABSTRACT
INTRODUCTION:
Cardiovascular (CV) events are a major cause of morbidity and mortality in haemodialysis (HD) patients. Hypertension, increased arterial stiffness and left ventricular (LV) hypertrophy are highly prevalent and are often poorly controlled. Volume overload is an important factor and survival could be improved by treatment strategies that preserve residual renal function (RRF), reduce blood pressure, and decrease arterial stiffness and LV hypertrophy. Angiotensin II receptor blocker (ARB) treatment can prevent CV events in patients with hypertension and heart failure. However, few data exist in patients with chronic renal failure and it is not known whether ARB treatment improves clinical outcome in HD patients. MATERIAL ANDMETHODS:
This is a randomized, controlled and double-blinded intervention study. A total of 82 HD patients from six Danish HD centres will be treated for a year with an ARB (irbesartan) or placebo. The inclusion criteria are urine output > 300 ml/day, dialysis vintage < 1 year and LV ejection fraction > 30%. The primary outcomes are change in RRF, LV hypertrophy, arterial stiffness and intra-dialytic haemodynamics.CONCLUSION:
If ARB-treatment improves RRF and intermediate CV endpoints in a group of newly started HD patients, it may improve the survival for this high risk population.FUNDING:
The trial is investigator-initiated, investigator-driven and supported by the Danish Agency for Science, Technology and Innovation and several private foundations.
