New NDT study [1] shows that `normal´ pre-dialysis blood pressure measurement is not reliable. “Without performing extended ambulatory BP recordings (44h - 48h) we approvingly accept an error rate of about 30% in the diagnosis of hypertension in dialysis patients, a highly vulnerable patient group with a dramatically elevated cardiovascular risk. This is why EURECA-m recommends ambulatory blood pressure monitoring as gold standard for the diagnosis for hypertension in hemodialysis patient."
