How Samsung Is Expanding Heart-Health Tracking With Galaxy Watch and Samsung Health

Samsung’s heart-health strategy is to make Galaxy Watch measurements more useful between medical appointments. At a Sept. 9, 2026 briefing in Seoul ahead of World Heart Day, digital health executive Choi Jong-min presented a combination of watch-based monitoring, Samsung Health guidance and health-data sharing with family members.268

From readings to a Heart Health Score

Galaxy Watch and Samsung Health already cover blood pressure, electrocardiograms (ECGs) and irregular-heart-rhythm notifications alongside measures such as sleep and physical activity. The Heart Health Score on the Galaxy Watch9 and Watch Ultra2 brings everyday factors into one assessment and offers personalized suggestions for healthier habits.81216

Briefing coverage describes the score’s inputs as sleep, activity, body composition and vascular stress. Samsung’s support page describes them more specifically as sleep time, BMI, activity levels and vascular load. Either way, the emphasis is on helping people understand habits they may be able to change—not on presenting the score as a medical diagnosis.112

Samsung Health also offers dietary guidance elsewhere in the app, including tips based on its Antioxidant Index. The available reporting does not establish that those dietary tips are generated by the Heart Health Score itself.32

Overnight changes and reasons to seek care

The new watches’ Vital Signs feature tracks five measures during sleep: heart rate, heart-rate variability, respiratory rate, skin temperature and blood oxygen. Briefing coverage says it compares readings with a person’s usual pattern to flag meaningful changes, though the available excerpts do not spell out the alert thresholds.1037

Samsung offered two examples of alerts leading people to seek medical attention. In Jordan, the company said an irregular-rhythm notification preceded the detection and treatment of atherosclerosis. In Brazil, repeated inconclusive ECG readings prompted a hospital visit. These are company-reported cases of follow-up after an alert, not evidence that the watch diagnosed either person’s condition.8

Connected Care extends the picture to family

Samsung’s Connected Care approach lets people share selected health information with relatives with their consent. Reporting from the briefing describes sharing sleep, heart-rate and activity information, medication records and, where available, other data such as blood pressure or blood-glucose records. A family member could notice a change in a parent’s activity or a missed medication entry and check in.2935

One account describes linking a family profile and Samsung account to share chosen information. Sharing a glucose record does not mean a Galaxy Watch measures glucose on its own. The available reporting also does not establish a specific procedure for importing readings from an external blood-pressure cuff.3544

What remains a future goal

Samsung is researching noninvasive continuous glucose monitoring from the wrist, but Choi described it as something the company wants to achieve, not a feature available on current watches. No commercialization timetable had been announced. Reporting also mentions work on genomic analysis without establishing it as a direct Samsung Health feature.373941

Some reporting anticipates updates for older Galaxy Watches, but it does not confirm a Watch8 release date or which new features that model would receive.9 For now, the clearest distinction is between the Watch9 and Ultra2 features Samsung has described, consent-based sharing through Samsung Health, and longer-term research that should not be mistaken for a shipping capability.12162941
