(Central News Agency, reporter Wu Chia-Hao, Taipei, 13th) Apple Inc. announced that it has enabled the Apple Watch hypertension notification feature in Taiwan today. The system will review relevant data on a 30-day cycle and remind the user when it detects signs that may indicate the onset of hypertension.
The hypertension notification feature is available on Apple Watch Series 9 and later models, as well as Apple Watch Ultra 2 and later models. This feature also has usage restrictions and is not suitable for individuals under 22 years of age or those who have already been diagnosed with hypertension. Pregnant women are also not suitable for use due to different characteristics of vascular waveforms during pregnancy.
Apple explained on its official website that hypertension is a major controllable risk factor for heart attack, stroke, and kidney disease, affecting approximately 1.3 billion adults worldwide. Since hypertension often has no obvious symptoms, and many people do not see a doctor regularly, it can often be missed even during clinical examinations due to a single measurement, and is therefore frequently undiagnosed.
The Apple Watch's hypertension notification feature analyzes the user's vascular response to heartbeats using data from the optical heart rate sensor. The algorithm runs continuously in the background, reviewing relevant data over a 30-day period; it sends a notification when it detects persistent signs of hypertension.
Users wearing an Apple Watch can receive notifications and gain important related health insights, helping them to adjust their lifestyle habits early or seek treatment.
Apple noted that the hypertension notification feature uses advanced machine learning technology, trained on data from multiple studies with a total of over 100,000 participants, and was subsequently validated through a clinical study with over 2,000 participants.
However, Apple also reminds users that the hypertension notification cannot detect all cases of hypertension. If a user receives a hypertension notification, it is recommended to use a third-party blood pressure monitor to record blood pressure data for 7 consecutive days and share it with their healthcare provider at their next appointment.
