An observational study in Atrial Fibrillation, sponsored by Nantes University Hospital. Recruiting at 1 site in France. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-29.
Sponsored by Nantes University Hospital · Observational
The objective of this single-center pilot study is, with the help of a connected watch, to show the absence of recurrence or maintenance of sinus rhythm in patients with a Post Operative Atrial Fibrillation (POAF) and to help treating cardiologists in the care of these patients.
Patients with postoperative atrial fibrillation meeting the study eligibility criteria
Exclusion Criteria:
Other: Clinical follow-up (ECG)
Other: Clinical follow-up (ECG) · Other: Ongoing monitoring
Clinical follow-up with a consultation at the University Hospital at 3, 6, and 12 months, with an ECG at each visit.
Once operated, patients will be monitored remotely via a computerized data transfer routine anonymized by the WITHINGS software, based on the data from the watch. It's contractually agreed with WITHINGS that the transmissions will be scheduled and transmitted weekly to the center.
To compare the rate of recurrence of paroxysmal or persistent atrial fibrillation with continuous 12-month postoperative cardiac surgery monitoring in patients with POAF versus traditional follow-up with ECG recording at 3, 6 and 12 months
Recurrence rate of paroxysmal or persistent Atrial Fibrillation (AF) (ESC 2020 Definition) over a 12-month follow-up period post cardiac surgery according to traditional ECG monitoring at 3, 6, and 12 months more or less combined with connected watch monitoring
Time frame: 12 months
Assessment of the rate of patients on anticoagulant therapy by follow-up modality
Rate of anticoagulant use at 3, 6, and 12 months according to rhythm status in both modalities
Time frame: 12 months
Evaluation of complication rates related to the different treatments according to the follow-up modality
Cardiovascular mortality, ischemic stroke, anticoagulant-related events
Time frame: 12 months
Assessment of the number of patients in AF
Postoperative AF rate in each group
Time frame: 12 months
Assessment of the duration of AF transitions
Postoperative AF rate over periods of more than 6 hours and/or 12 hours
Time frame: 12 months
Assessment of quality of life and satisfaction with use by follow-up modality
European Quality of Life-5 Dimensions (EQ-5D), (the maximum value is 3 (wich is the worse outcome) and the minimum is 1 (wich is the best outcome)), before intervention, at 3, 6 and 12 months
Time frame: 12 months
Assessment of quality of life and satisfaction with use by follow-up modality
Hospital Anxiety and Depression scale (HAD) scores, (the maximum value is 21 (wich is the worse outcome) and the minimum is 0 (wich is the best outcome)), before intervention, at 3, 6 and 12 months
Time frame: 12 months
Evaluate the appropriateness of each of the two modalities with treating cardiologists
Satisfaction questionnaire for treating cardiologists
Time frame: 12 months
