Wearable Blood Pressure Devices to Identify Masked Uncontrolled Hypertension.

Uncontrolled out-of-office blood pressure (BP), measured by either home BP monitoring (HBPM) or ambulatory BP monitoring, has been shown to predict higher cardiovascular risk. However, HBPM could not identify daytime BP surge, which leads to underestimation of future risk among treated hypertensive individuals. HeartGuide provides validated out-of-office BP measurements, along with activity/sleep recordings. The present study is designed to examine whether BP monitoring with the HeartGuide could identify masked uncontrolled hypertension in controlled hypertensive patients based on office BP. We will enroll hypertensive patients with controlled office BP according to their cardiovascular risk profile. We will also examine prevalence of post-prandial BP changes and BP variability using HeartGuide.
