Abstract

Accurate assessment of blood pressure (BP) is critical for the diagnosis and management of hypertension and is frequently performed sub-optimally in clinical practice. This study included 405 patients referred with uncontrolled hypertension to a tertiary Hypertension Clinic. Conventional attended office BP measurements significantly overestimated BP levels when compared to gold-standard daytime ambulatory BP. Measurements obtained by a standardized unattended automatic office BP measurement protocol demonstrated substantially higher concordance with daytime ambulatory BP. However, in the presence of a white coat component, even unattended automated BP measurements can overestimate ambulatory BP readings. Therefore, ambulatory BP measurements should be obtained wherever feasible.
