LOAD limits for ambulatory pulse pressure and double product in normotensive and hypertensive subjects.

Objective: The aim of this study was to to determine possible daytime (awake hours) and nighttime (sleeping hours) LOAD limits for ambulatory pulse pressure (PP) and double product (DP) in hypertensive (HT) subjects and secondly to assess whether there were significant differences in the LOAD values between hypertensive (HT) and normotensive (NT) subjects.

Methods: Seventy-eight untreated essential HT (46 female, 32 male; mean age 51.9+/-1.
