Observational Study on Atrial Fibrillation After Cardiac Surgery

This study is looking at how common and impactful atrial fibrillation (AFib), a type of irregular heartbeat, is for patients who have had heart surgery. AFib is a very common issue after heart surgery, and it can lead to longer hospital stays, a higher risk of stroke, and other complications. Researchers will use a Vivalink wearable life sensor (a device that collects EKG data) to monitor your heart rhythm for up to 30 days after you leave the hospital. The goal is to better understand the full burden of AFib after surgery. You may be able to join if you are between 20 and 90 years old and are having elective open-heart surgery.

Study design
This is an observational study planning to enroll 150 participants. It is not testing a new drug or treatment.
What's involved
You would wear a Vivalink wearable life sensor to collect EKG data. This monitoring would continue for up to 30 days after you are discharged from the hospital.
Compensation
Not stated in the trial record.
Follow-up
Your heart rhythm will be measured for up to 30 days after you are discharged from the hospital.
