What the research found
Preliminary American Heart Association research followed 4,190 adults ages 40 to 85 with stage 2 high blood pressure (at least 140/90 mm Hg; average age 62.4; 46 percent women and 54 percent men) at one hospital in Sindh, Pakistan, from January 2025 to January 2026. A model using a portable cuff and a wrist-worn device flagged hypertensive-crisis risk up to 72 hours ahead. Over 12 months, 312 people had 418 crises, about 7 percent of participants. Among people with a positive alert, about 32 percent had a crisis. Among people with no alert, 97.4 percent stayed crisis-free. This conference abstract is not a peer-reviewed study. It does not turn a wristband into a diagnosis. Not medical advice.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
