Stroke Risk Could Be Flagged Early Using Apple Watch Technology, Studies Show

The latest research shows that wearables could soon be a vital part of tracking your heart health.

For millions at risk of stroke, a simple tap on the wrist could one day save lives. New studies from the Amsterdam University Medical Center and St. Bartholomew’s Hospital in London showed that wearables, such as the Apple Watch, can improve the detection of atrial fibrillation compared to standard care. Atrial fibrillation, often referred to as A-fib, is a heart arrhythmia, which means an irregular or abnormal heartbeat. The condition can cause blood clots and is one of the leading causes of a stroke.

The Amsterdam study enrolled 437 patients aged 65 or older with elevated stroke risk and required 219 of them to wear an Apple Watch to track their heart rate for 12 hours a day for 6 months. The remaining 218 patients didn’t wear a watch and relied on standard care.

The experiment detected heart arrhythmias four times more frequently in patients wearing an Apple Watch versus those who didn’t. Specific versions of the Apple Watch use photoplethysmography, a heart rate-detecting LED light sensor, and have a built-in single-lead electrocardiogram sensor to read your heart rate.

Wearables that track heart rate and other health markers aren’t new, and previous studies have shown promise in detecting A-fib. Although wearables are known to track this type of data, no prior research has examined how well they detect potential health risks for A-fib.

«We saw that after six months we diagnosed and treated 21 patients in the group wearing the smartwatch, of whom 57% were asymptomatic,» said Michiel Winter, a cardiologist at Amsterdam UMC, in a statement. «This was against just five diagnoses in the group receiving standard care, all of whom experienced symptoms.»

The second clinical study, conducted by St. Bartholomew’s Hospital, showed that the Apple Watch could also be beneficial for detecting A-fib symptoms earlier and for monitoring patients after a standard treatment, such as a catheter ablation. The hospital found that patients could record clinical-grade ECGs on their Apple Watches at home when experiencing symptoms. Similar to the first study, the hospital found that patients using an Apple Watch detected A-fib earlier and more frequently than those receiving standard care. Catching symptoms earlier also reduces anxiousness and the likelihood that a patient will need to be hospitalized.

The findings from these studies show that wearables such as the Apple Watch could be used for long-term heart screening to detect heart health abnormalities and improve patient care for those in treatment. And it can help diagnose those who don’t know they have the condition.

«Using smartwatches with PPG and ECG functions aids doctors in diagnosing individuals unaware of their arrhythmia, thereby expediting the diagnostic process,» said Winter.
