Introduction
Hypertension is an established, strong trigger of cardiovascular events. However, the relative importance of its various components remains unclear. The prognostic value of hypertension in patients with end-stage renal disease (ESRD) has long been taken for granted and for this reason there is a paucity of high-quality studies in this area. There are very few prospective studies aimed at clarifying the impact of arterial pressure components on the incidence of cardiovascular complications in ESRD. Uncertainty enshrouds the optimal timing of blood-pressure (BP) measurement in relation to dialysis treatment, the threshold for treatment and the prognostic usefulness of 24-h ambulatory monitoring. In this brief review I will touch upon these important, unresolved arterial-pressure issues in ESRD.
Systolic, diastolic or pulse pressure?
Diastolic BP depends on peripheral vascular resistance and on central artery stiffness. High peripheral vascular resistance raises diastolic pressure while high arterial stiffness has an opposite influence on this component so that the relative contribution
