A representative value for 24-hour monitored ambulatory blood pressure

Abstract

Several shorter-term alternatives for whole-day ambulatory monitoring of blood pressure using Pressurometer III or conventional sphygmomanometer were evaluated in 12 male patients with mild hypertension. Averages of BP reading at 8 AM once, 3 consecutive-readings either with Pressurometer or manually, serial readings for 2-hour intervals from 8-10 AM and 2-4 PM were compared with that of 24-hour ambulatory, non-invasive BP readings by Pressurometer. Both systolic and diastolic 2-hour BP averages in the morning (8 to 10 o'clock) correlated more strongly with 24-hour averages (r = 0.91 and 0.91) than the 3 consecutive (r = 0.88 and 0.66) or single (r = 0.49 and -0.35) reading alternatives did. In conclusion, the average of serial readings obtained during 2-hour monitoring period from 8 to 10 AM is a reliable predictor of 24-hour ambulatory BP and represents it more closely than the conventional single or multiple BP readings.

Diagnostic accuracy of manual office blood pressure measurement in ambulatory hypertensive patients in Korea

“…Thus, recent guidelines recommend the implementation of ABP in clinical practice [ 7 , 11 - 15 ]. However, there have been few studies on the relationship between OBP and ABP in Korean populations [ 16 , 17 ].…”

The validity of a daytime ambulatory blood pressure to diagnose masked hypertension

“…Prior studies reported that the average of serial BP readings obtained during a 2-hour monitoring period is a consistent predictor of the whole-day BP [9,10]. In 2008, Ernst et al studied ABPM in 569 patients with shortened intervals of 4-, 6-and 8 hour sessions and indicated that the shortened ABPM time period of 6 to 8 hours may potentially approximate the patient's overall BP obtained from a full 24 hour average [11].…”
