What this trial studies

This clinical trial is designed to compare the effectiveness of the Aktiia Optical Blood Pressure Monitoring (OBPM) device against standard home blood pressure monitoring (HBPM) in patients with hypertension. Participants will be divided into three groups based on their treatment status and blood pressure control, with each group undergoing a series of blood pressure measurements while taking different antihypertensive medications. The study will last between 4 to 19 weeks, depending on the group, and will involve continuous monitoring with the Aktiia device. The goal is to assess the accuracy and reliability of the Aktiia device in managing blood pressure in hypertensive patients.
