Thanks to the Apple Watch, time may be up for this silent killer

Study aims to find out if it can reduce risk of stroke by detecting early signs

Apple wants to know if its Apple Watch can reduce the risk of stroke by detecting early signs of atrial fibrillation (AFib). To help find out, the company announced a partnership with Johnson & Johnson on Tuesday to conduct a three-year stroke study. 

Apple and Johnson & Johnson are seeking eligible adults in the U.S. ages 65 and older to participate in the study, called Heartline. Participants would download the Heartline Study app on their iPhones, along with an electrocardiogram (ECG) app, to see if the Apple Watch can successfully detect irregular heart rhythms. 

“Heartline is a study that has the potential to fundamentally change our understanding of how digital health tools, like the ECG app and irregular rhythm notification feature on Apple Watch, could lead to earlier detection of AFib, helping patients understand and directly engage in their heart health, prompting potentially lifesaving conversations with their doctors, and improving health outcomes,” said Dr. C. Michael Gibson, co-chair of the Heartline executive committee and professor of medicine at Harvard Medical School, in a press release. 

The goal of the study is to see if the Apple Watch can better detect early signs of AFib, which is the leading cause of stroke, but doesn’t always show symptoms. According to a 2017 study, 30% of people don’t know they have AFib until suffering a severe cardiovascular event, such as a stroke. 

Participants of the study will get heart health tips, as well as surveys and questionnaires to fill out, each week during the study. You’ll need an iPhone to participate, but you don’t need to own an Apple Watch. Apple will give participants a discount on the purchase of an Apple Watch or it can loan one out to those involved in the study. 

Apple also has other health studies in the works, including a hearing study that analyzes how daily sound exposure will impact your long-term hearing health. There’s also a women’s health study that looks at menstrual cycles and mensuration tracking, and a heart and movement study to better detect early signs of heart disease. 

More than 400,000 people participated in Apple’s original heart study that monitored irregular heart rates on the Apple Watch. The study was published in November in the New England Journal of Medicine and revealed that a little over 2,000 people received a notification about an irregular pulse. 

The OnePlus Buds Clip are a new pair of open-ear earbuds built around a simple convenience. They join Sony’s LinkBuds Clip in the growing ear-cuff category, but either OnePlus bud can go on either ear.

Sensors recognize how the earbuds are being worn and route the audio channels accordingly. There’s no label to check before putting them on, and the feature also works when only one bud is used.

We buy fitness bands and activity trackers to keep tabs on our exercise, but it is easy to forget to start tracking or switch modes when moving between different activities. For Fitbit and Pixel Watch users, that could soon become a lot less annoying, as Google is rolling out a major upgrade to automatic activity tracking that can recognize more than 100 types of exercise, up from just 10 before.

Google first showed off the improved tracking earlier this month alongside the Fitbit Edge. It is now coming to Fitbit Air and the Pixel Watch 3, 4, and 5, and Google claims the added context behind the system makes workout detection nearly twice as accurate while cutting missed activities by more than half. Fitbit Edge will support it too.
