Using Apple Watch to Monitor Heart Failure Changes Over Time

Researchers want to see if an Apple Watch can help predict changes in your heart's fitness and warn of worsening heart failure by continuously tracking your biometric data (like heart rate and activity). The study aims to make heart health monitoring easier and more accessible for people with heart failure who might not be able to travel to specialized cardiac centers. This could help doctors spot problems earlier and keep you healthier.

Right now, doctors usually get a single snapshot of how well your heart is working at appointments, which may not catch early warning signs of decline. Travel to specialized testing centers is difficult for many patients due to distance, resources, or health barriers. This study tests whether continuous monitoring through wearable devices could provide a more practical, equitable way to track your heart health and catch problems before they become serious.
