The watch may be smart, but it can't replace your doctor
The Apple Watch has been quite successful as a smartwatch. The company would also like it to succeed as a medical device. The recently published results of the Apple Heart Study in the New England Journal of Medicine show there is still a long way to go.
To test the device’s ability to aid diagnosis, a group of researchers enrolled almost 420,000 Apple Watch wearers in a study. Participants were monitored for about four months. Over that time, 2,161 of the study participants were notified of an irregular pulse, representing just over 0.5% of the sample.
Of the 450 participants who returned patches, atrial fibrillation was confirmed in 34%, or 153 people. Those 153 are about 0.04% of the 420,000 participants. But this result wasn’t calculated from any of the numbers above. It specifically refers to the subset of patients who had an irregular pulse notification while wearing their confirmatory patch. That’s a very small minority of participants. Of the 86 who got a notification while wearing a patch, 72 had confirmed evidence of atrial fibrillation.
Other methods to screen and diagnose people with atrial fibrillation are available. A systematic review of mobile health devices for atrial fibrillation found 22 studies between 2014 and 2019 that reported on many of them. Some had sensitivities and specificities pretty close to the ideal of 100. None are close to as large as this study, though.
