The goal of this clinical trial is to learn if screening for atrial fibrillation (AFib), a common irregular heart rhythm, through daily home blood pressure monitoring will decrease the time to atrial fibrillation diagnosis in older adults with hypertension. The main question it aims to answer is:
-- Does introducing screening for AFib using a blood pressure monitor with AFib detection technology decrease time to AFib diagnosis in patients with high blood pressure, compared to usual care using a conventional home blood pressure monitor with no AFib detection?
Participants will participate in two phases of the study: (1) clinical trial and (2) the registry.
During the 6-month clinical trial period, participants will be asked to:
* Take blood pressure measurements twice daily * Answer short weekly mobile app-based surveys * If assigned, complete continuous heart monitoring for 2 weeks and complete 1 blood test
During the 12-month registry period, participants will be asked to:
* Take blood pressure measurements twice daily * Answer monthly mobile app-based surveys
Researchers will compare standard blood pressure measurements and AFib screening blood pressure measurements to see if there is a difference in the time to AFib diagnosis and other cardiovascular events.
