Abstract There is a paucity of high quality studies on the prognostic importance of arterial pressure in end-stage renal disease. Furthermore, the optimal timing for blood pressure (BP) measurements (pre- or postdialysis), and the prognostic value of 24-hour ambulatory BP monitoring in these patients remain to be established. In end-stage renal disease patients without diabetes and heart failure, predialysis systolic, diastolic, and pulse pressure are strongly and independently related to left ventricular mass, and the strength of these relationships is higher than that between the corresponding postdialysis values and left ventricular mass. Average predialysis systolic pressure (monthly average) is associated with left ventricular mass as strongly as 24-hour systolic BP, which suggests that the average routine predialysis BP taken over 1 month may be equally representative of the "true" BP (the integrated BP load) than 24-hour ambulatory BP monitoring. Mortality is U shaped in large hemodialysis databases. In the only prospective study that adequately controlled for cardiac function at baseline, it was shown that hypertension is associated with a higher risk of developing congestive heart failure, and that patients with left ventricular hypertrophy or chronic heart failure are at a much higher risk of mortality than patients without these complications. The role of arterial stiffening (pulse pressure) as a cardiovascular risk factor has been firmly established in an analysis of a very large dialysis database in the United States, and by recent studies based on direct measurements of pulse wave velocity.
