A new study led by researchers at UHN's Peter Munk Cardiac Centre and the Ted Rogers Centre for Heart Research shows that data from a consumer smartwatch can detect early signs of worsening heart failure — days to weeks before unplanned medical care is needed.
The findings, recently published on the cover of Nature Medicine, suggest that monitoring physical fitness capacity with wearable devices, such as Apple Watch, could help identify real-time changes in heart health without additional tests or extra effort from patients.
These changes can act as early warning signs, allowing clinicians to intervene faster with more responsive care.
Researchers also found that patients with a 10 percent or more drop-in daily cardiopulmonary fitness had a more than three-fold increased risk of unplanned hospitalization or urgent treatment.
