What this Trial Is About
Researchers are investigating the occurrence and impact of atrial fibrillation (AF) in patients undergoing cardiac surgery. AF is a common complication after such surgery, affecting 30 to 60% of patients and leading to longer hospital stays, increased risk of stroke, and additional treatments like anticoagulation. This observational study aims to better understand how often AF occurs and identify risk factors to improve prediction models for patients undergoing elective open heart surgery. Participants will wear Vivalink wearable life sensors that collect electrocardiogram (EKG) data to monitor heart rhythms during and after surgery. The study focuses on tracking AF and other arrhythmias up to 30 days following hospital discharge. Data gathered from these devices will help researchers analyze the prevalence of AF and related heart rhythm issues in this patient group. During the study, patients will be monitored continuously with the wearable sensors to collect heart rhythm data. Researchers will evaluate the presence of atrial fibrillation and other arrhythmias within 30 days after surgery. Participants’ clinical and epidemiological information will also be collected to explore risk factors. The study is conducted by Brigham and Women's Hospital and plans to recruit adults aged 20 to 90 years undergoing elective cardiac surgery.
