Attended and Unattended Automated Office Blood Pressure Measurements Have Better Agreement With Ambulatory Monitoring Than Conventional Office Readings.

Background: Automated office blood pressure (AOBP) measurement is superior to conventional office blood pressure (OBP) because it eliminates the "white coat effect" and shows a strong association with ambulatory blood pressure.

Methods And Results: We conducted a cross-sectional study in 146 participants with office hypertension, and we compared AOBP readings, taken with or without the presence of study personnel, before and after the conventional office readings to determine whether their variation in blood pressure showed a difference in blood pressure values. We also compared AOBP measurements with daytime ambulatory blood pressure monitoring and conventional office readings.
