The Apple Watch on the wrist can serve as an important medical monitoring tool under the right circumstances. According to MyHealthyApple and MacRumors, Stanford researchers funded by Apple, have determined that the Apple Watch can accurately measure the weakness (or rather, the distance traveled six minutes) of patients with cardiovascular disease while at home. Using a personal smartwatch was almost as good as a clinic test, Stanford’s study revealed.
Researchers collected the data using the Apple Watch Series 3 and a custom-made VascTrac app, but third-party software is unlikely to be needed in the future. WatchOS 7 includes a six-minute walk test and other mobility data, and you can review your performance in the Health app on your iPhone (in the Browse tab under Respiratory).
The findings suggest that the Apple Watch and other smartwatches can save patients the hassle of visiting their doctor to measure their functional capacity ̵
