PRAGUE—Decreases in pulse pressure (PP), and to a lesser extent increases, predict worse survival in the first year for patients new to hemodialysis (HD), new findings suggest. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) changes also are associated with poorer outcomes. These results are consistent across the entire range of blood pressure (BP) and pulse pressure measurements within the first 30 days of starting dialysis.
