Samsung study points to Galaxy Watch hypertension alerts

Samsung has started recruiting Galaxy Watch users for a new study focused on hypertension. The interesting bit is not simply that Samsung wants more health data, but what it might eventually do with it.

Samsung wants more than the occasional blood pressure reading

Samsung already offers manual blood pressure checks on compatible Galaxy Watch models, while the newer Blood Pressure Trend feature looks at overnight data to estimate morning blood pressure.

The new hypertension study goes beyond simply giving users another blood pressure reading. Samsung is collecting Galaxy Watch and phone sensor data specifically to study hypertension, with the stated aim of using that research to help create future health features. That points to Samsung exploring whether the watch can do more than estimate blood pressure. 

Hypertension alerts would be the obvious next step

Our guess, and this is speculation, is that Samsung is looking beyond showing people blood pressure estimates. The bigger prize would be identifying longer-term patterns that suggest someone may have hypertension, then prompting them to check with a proper cuff or seek medical advice.

There is already plenty of movement in that direction elsewhere. Apple introduced hypertension notifications that look for cardiovascular patterns over time rather than trying to turn the Watch into a traditional blood pressure monitor.

Google followed a remarkably similar research path. It recruited Pixel Watch users for a hypertension study last year, collecting wearable data and comparing a subset of it with ambulatory blood pressure measurements. That work has since fed into Google’s wider Health Guardian push, including Blood Pressure Trends for Fitbit and Pixel Watch devices.

Samsung therefore has plenty of incentive to push further. Giving someone a morning blood pressure estimate is useful, but automatically noticing that their cardiovascular data has been drifting in the wrong direction for several weeks would be even more useful.

Who can join the study

Samsung is recruiting participants through the Samsung Health app, with the invitation appearing in the Promotions section for eligible users. The study uses data from both the Galaxy Watch and connected phone, so Samsung is clearly looking at a broader set of health signals rather than just individual blood pressure readings.

For Galaxy Watch owners, it is worth checking Samsung Health to see whether the invitation has appeared. The study itself may not change anything on your watch today, but it gives us a pretty good indication of where Samsung’s cardiovascular health work is heading next.
