Abstract

Objective To study the relationship between brachium-ankle pulse wave velocity and 24hABPM, conventional blood pressure and 24 hABPM in prehypertensive subjects.

Methods 210 subjects were enrolled with prehypertension. Conventional blood pressure, 24-h ABPM and baPWV were performed. The patients were divided into dipper and non-dipper according to the decrease rate of nighttime MBP.

Results 1) Conventional blood pressure was obviously higher than mean 24-h BP, mean daylight BP and mean nighttime BP (p<0. 05). Conventional SBP was correlated with mean daylight BP (r=0.431, p=0.023), and with mean 24-h SBP (r=0.282, p=0.037). Conventional DBP was related to mean daylight DBP (r=0.241, p=0.0397), and related to 24-h blood pressure (r=0317, p=0.018). 2) baPWV was positive related to 24-h SBP, daylight SBP and PP, daylight and nighttime SBP load. 3) Conventional SBP was significant associated with daylight SBP (r=0.577, p=0.022) and 24-h SBP (r=0.611, p=0.019), and conventional DBP was significant related to daylight DBP (r=0.582, p=0.184) and 24-h DBP (r=0.693, p=0.007) in non-dipper prehypertensive patients. 4) baPWV was significant positive correlated with 24-h SBP, DBP, PP, daylight SBP, PP, SBP load, and nighttime SBP, PP, SBP load.

Conclusion There is a more value of 24-h ABPM in non-dipper prehypertensive patients than dipper prehypertensive patients. baPWV was closely correlation with 24-h SBP, daylight SBP and PP, daylight and nighttime SBP load in two groups.

  • Conventional blood pressure
  • Prehypertensive
  • 24-h ambulatory blood pressure monitoring
  • brachium-ankle pulse wave velocity
