Official Title: Post-Surgical Enhanced Monitoring for Cardiac Arrhythmias and Atrial Fibrillation (SEARCH-AF): A Randomized Controlled Trial
Brief Summary:
The aim of the SEARCH-AF trial is to evaluate a novel diagnostic tool for detecting post-operative atrial fibrillation or flutter (POAF/AFL) in cardiac surgical subjects during the early, sub-acute post-operative period. The population includes cardiac surgical subjects who have either developed or are at risk for developing new onset POAF/AFL and who are at risk for stroke, as determined by their CHA2DS2-VASC (congestive heart failure, hypertension, age ≥75 years (2 points), diabetes mellitus, previous stroke/transient ischemic attack (TIA) (2 points), vascular disease, age 65-74 years, sex class (female)) score. These subjects must not have had a history of AF/AFL before cardiac surgery.
The intervention group will undergo 30 days of continuous cardiac rhythm monitoring with an adhesive, patch-based monitor (Medtronic SEEQ™ mobile cardiac telemetry system). The control group will receive usual care, which does not involve planned cardiac rhythm testing within the first 30 days after study randomization. The primary outcome is documentation of sustained atrial fibrillation or flutter within the first 30 days after randomization. In addition, subjects in both groups will undergo 14 days of continuous cardiac rhythm monitoring with the Medtronic SEEQ™ mobile cardiac telemetry system at 6±1 months after their index cardiac surgery.
