Hypertension notifications available today on Apple Watch
Starting today, hypertension notifications on Apple Watch are available in the Philippines, which can alert users if signs of hypertension — or chronic high blood pressure — are detected.1
Hypertension is the leading modifiable risk factor for heart attack, stroke, and kidney disease, and impacts approximately 1.4 billion adults globally. It is frequently undiagnosed because it often has no symptoms, many people do not see a doctor regularly, and even during a clinical visit, it can be easily missed with a single measurement.
Hypertension notifications on Apple Watch use data from the optical heart sensor to analyze how a user’s blood vessels respond to the beats of the heart. The algorithm works passively in the background reviewing data over 30-day periods, and will notify users if it detects consistent signs of hypertension. These notifications provide users with valuable insights into their health as it relates to this widespread condition simply by wearing their Apple Watch, so they can begin making potentially lifesaving behavioral changes or start treatment to reduce their risk of serious, long-term health events.
As with all of Apple’s health features, hypertension notifications are grounded in rigorous scientific validation. The feature was developed with advanced machine learning and training data from multiple studies totaling over 100,000 participants. Its performance was then validated in a clinical study of over 2,000 participants. While hypertension notifications will not detect all instances of hypertension, with the reach of Apple Watch, many lives will be meaningfully changed due to their awareness of this asymptomatic condition.
If users receive a hypertension notification, it is recommended that they log their blood pressure for seven days using a third-party blood pressure cuff and share the results with their provider at their next visit, which is consistent with the latest American Heart Association guidelines for the diagnosis and management of hypertension.
Hypertension notifications are currently available on Apple Watch Series 9, Apple Watch Series 10, Apple Watch Series 11, Apple Watch Ultra 2, and Apple Watch Ultra 3. Hypertension notifications will not be initially available in the Philippines on Apple Watch Series 12 or Apple Watch Ultra 4, as additional regulatory clearances for the feature on these models are in process; availability for these models is expected next year. Please see the feature availability status for more information.
