Apple Heart Study winds down ahead of January completion date

Last updated

A number of early participants in the Apple Heart Study received messages this weekend saying that their contributions to the program are complete.

In November of 2017, during the Apple Watch Series 3 release event, Apple announced the Apple Heart Study. The groundbreaking study, conducted in conjunction with Stanford Health, was designed to determine whether heart rate data collected from Apple Watch can be used to identify irregular heart rhythms and conditions like atrial fibrillation.

Earlier this month, Apple announced that it was closing enrollment for the study, and on Sept. 1, many participants received in-app notifications that the program was complete.

"Thank you for participating in the Apple Heart Study," read the notification received by one AppleInsider staffer. It went on to list his number of heart data rhythm contributions, as well as number of days in the study. Numerous Twitter users posted screenshots of similar messages on Saturday.

Along with the notification, participants were asked to take part in a survey from Stanford Health, with questions ranging from general health queries to whether users would be interested in "continuing to use the Apple Heart Study App to monitor your pulse for irregularities." The latter suggests Apple is considering keeping the app, which includes a mechanism to notify owners of detected irregularities, live following the study's conclusion as a value-added Apple Watch feature.

Apple had earlier announced the end date for the study as Jan. 31, 2019. It is unclear if the September announcement marks a study-wide change, though Apple and Stanford Health are likely closing the window for data contributions in stages, as the notifications appear to be going out to those participants who were among the first to sign up. While not confirmed, the Apple Heart Study might continue to collect data from Apple Watch owners whose data warrants further study.

Since its inception, the study has coincided with several news stories in which the Apple Watch has saved the lives of users by informing them in time of potential heart conditions and other maladies.

I was notified and took the survey. 

During my participation I noticed that my contributions increased dramatically faster when I wore my Apple Watch while sleeping. In turn, I started wearing my AW overnight much more frequently figuring more contributions were likely to better than fewer. 

I’m hoping we’ll hear about what sort of results came from the study.

Got the notification and survey yesterday. Are there any alternative apps that do the heart monitoring and notification if it detects a problem?

My Watch and stock Health app have already notified me of an irregular heartbeat on a couple occasions. It takes a while for the combo to figure out what your normal range is. When it detects something way out of the parameters, it sends an alert.

It's still early days as far as these devices giving what would constitute medical advice; but, besides what Apple provides with the watch/watchOS itself, you might want to keep an eye on what https://cardiogr.am/ is doing.

I also use these:

Received the completion survey as well. I did get three notifications of unusual heart rate increase while still; so that feature seems invaluable in my opinion. (I had no need to panic though as I was playing chess in the park when those notifications happened) who knew my heart could get a workout from chess stress?
