Study of Continuous Heart Rhythm Monitoring to Detect Atrial Fibrillation After Noncardiac Surgery

What this Trial Is About

This research focuses on patients undergoing noncardiac surgery to detect postoperative atrial fibrillation POAF, a condition linked to long-term health issues but often missed in routine care. The study aims to determine how often clinically important POAF occurs by using continuous heart monitoring after surgery. It is a multicenter prospective cohort study sponsored by the Population Health Research Institute. Participants will wear a portable cardiac monitoring device to continuously record their heart rhythm for up to 14 days, starting within 72 hours after their surgery. The monitoring period can last up to 14 days, and the study observes the incidence of POAF and related heart rhythm problems within 35 days of surgery. This approach seeks to improve detection compared to usual clinical monitoring. During the study, researchers will collect continuous ECG data, and participants will be followed to track heart rhythm events and any complications. The main measurement is the occurrence of clinically important POAF within 35 days after surgery. Secondary outcomes include other heart rhythm disturbances and death within the same period. The total participation time includes continuous monitoring and follow-up assessments within 35 days after surgery.
