Arrhythmias & electrophysiologyCohort study
Coronary artery disease in atrial fibrillation ablation: impact on arrhythmic outcomes
- Prospective cohort study
- single-centre
- consecutive patients
Authors' conclusion
In patients undergoing CT scan before AF ablation, critical CAD was diagnosed in 7.1% of patients. Coronary artery disease and revascularization were not independent predictors of recurrence
Study context
- Population
- Patients with atrial fibrillation (AF) undergoing first cryoballoon catheter ablation (CA) with contrast computed tomography (CT) pre-ablation, Universitair Ziekenhuis Brussel, Belgium, 2015–2019
- Participants
- 576 consecutive patients
- Exposure
- Coronary artery disease (CAD) vs no CAD on pre-ablation CT
- Critical CADn = 41
- CADn = 122
- Outcome
- Prevalence of CAD detected by cardiac CT pre-ablation; impact of CAD and revascularization on outcomes after AF ablation
Main finding
As reported in the abstract
Prevalence of CAD at CT
Observational data: associations, not effects.
Further findings
| Outcome | HR |
|---|---|
| Atrial tachyarrhythmia (AT) recurrence: predictors · follow-up — Critical CAD | 1.79 |
| Atrial tachyarrhythmia (AT) recurrence: predictors · follow-up — Persistent AF · independent predictor (Cox multivariate) | 2.93 |
| Atrial tachyarrhythmia (AT) recurrence: predictors · follow-up — Left atrium volume index · independent predictor (Cox multivariate) | 1.04 |
- Atrial tachyarrhythmia (AT) recurrence: predictors: Cox univariate only; not an independent predictor in multivariate analysis
Atrial tachyarrhythmia (AT) recurrence: predictors · follow-up
- CAD and revascularization not independent predictors of recurrence
