Smartwatches vs. heart disease: brazilian study tests AI-Powered early warning system
NCT ID NCT07174206
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study is testing whether a smartwatch, combined with artificial intelligence and remote doctor check-ins, can help detect heart issues like atrial fibrillation and unstable angina earlier than usual. Researchers at the University of Sao Paulo will enroll 520 adults with heart conditions or recent heart procedures. Participants will wear a smartwatch and a portable heart monitor for up to 45 days, and doctors will be alerted if the watch detects something concerning. The goal is to see if this approach is practical, accurate, and could improve patient care.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Smartwatch and portable holter devices for heart monitoring
What this could lead to
If successful, this could show that smartwatches and AI can help doctors catch heart rhythm problems early and manage patients remotely, potentially reducing hospital visits.
What could go wrong
This is an early feasibility study, not a large treatment trial. The smartwatch may miss some heart events or cause false alarms, and results may not apply to all heart patients.
