Investigating Atrial Fibrillation After ICU Discharge

Post Intensive Care Unit Atrial Fibrillation

NA · Centre Hospitalier Universitaire de Besancon · NCT05860894

This study is testing how often atrial fibrillation comes back in adults who had it while in the ICU, using a heart monitor for a year to see how it affects their recovery.

What this trial studies

This study examines the recurrence of atrial fibrillation (AF) in patients who have been discharged from the intensive care unit (ICU). It focuses on adults who experienced new onset AF during their ICU stay and aims to monitor their heart rhythm for up to one year using an implantable ECG Holter device. The research seeks to understand the long-term implications of AF in critically ill patients and the factors that may contribute to its persistence post-ICU. By gathering data on AF recurrence, the study hopes to improve patient outcomes and management strategies.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who experienced new onset atrial fibrillation during their ICU stay.

Not a fit: Patients with a documented history of atrial fibrillation or those admitted to the ICU after cardiothoracic surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better monitoring and management of atrial fibrillation in patients after ICU discharge.

How similar studies have performed: While there is limited data on the long-term persistence of AF post-ICU, similar studies have shown the importance of monitoring heart rhythm in critically ill patients, suggesting potential for success.
