Samsung has announced that it will shut down its “Vascular Load” feature on Galaxy Watch, replacing it with a new metric.
In a notice sent to users (via Reddit), Samsung explains that it will shut down support for measuring a user’s “Vascular Load” on Galaxy Watch starting with the next major update One UI 9 Watch (Wear OS 7) and Samsung Health 7.0. This affects Galaxy Watch owners in the United States, with previous data going away.
What is “Vascular Load?”
Samsung previously explained the feature as follows:
While you sleep, [Galaxy Watch] reads Photoplethysmogram (PPG) waveforms – optical signals associated with blood flow during sleep. It measures blood volume and vascular stiffness and precisely analyses changes in stress on blood vessels. Because diet, stress, and rest all affect this metric, regular monitoring shows which habits to fine-tune and helps you cut cardiovascular risk before it takes hold.
