Dialysis patients have 10–20 higher mortality rates compared to controls. Factors discussed to influence mortality in dialysis patients are hypertension, left ventricular hyper-trophy (LVH), increased pulse pressure, phosphorus, calci-fication, inflammation, malnutrition, fluid and sodium balance , interdialytic weight gain, removal of middle molecule uraemic toxins and residual renal function (RRF) [1]. LVH and hypertension are frequent findings in dialysis patients
