First seen Jun 26, 2026 · Last updated Aug 21, 2026 · Updated 2 times
Summary
This study tests different strategies to help people from diverse backgrounds monitor their blood pressure at home. About 330 adults with uncontrolled high blood pressure will receive training on using a blood pressure monitor and a mobile app, plus SMS reminders and education. The goal is to see if these tools safely improve blood pressure control and are cost-effective.
