Summary

The Hypertension Canada Clinical Practice Guidelines for blood pressure measurement using AOBP recommend against any wait time prior to commencing the measurement. The recent AHA guidelines however call for a 5-minute rest first. In uncontrolled hypertension, AOBP is typically higher than the daytime readings from ambulatory blood pressure monitoring (ABPM), but this is not the case for patients with controlled hypertension.

Detailed description

Objective: Does a 5 minute rest or no rest before measurement using AOBP provide the most accurate reading in patients with controlled and uncontrolled hypertension, and in patients with white coat hypertension compared to daytime ABPM? Implications: Through this study, we hope to: (i) Advance the understanding of the role of AOBP in measuring blood pressure. (ii) Determine whether a 5-minute rest, or no rest at all is needed prior to AOBP measurement. (iii) Assess the relationship of AOBP to daytime ABPM for patient with controlled and uncontrolled hypertension and in patients with white coat hypertension.
