Body Fat Distribution and Left Atrial Reverse Remodeling After Catheter Ablation for Atrial Fibrillation
Authors' conclusion
Central adiposity was associated with a lack of LARR after CA
Study context
- Population
- Nonobese patients with atrial fibrillation (AF) undergoing first catheter ablation88 men
- Participants
- 116 patients
- Exposure
- Body size metrics and fat parameters and left atrial (LA) reverse remodeling
- Outcome
- Lack of LARR (<15% reduction or increase in LA volume index)
- Follow-up
- 6 months after CA
Main finding
As reported in the abstract
Lack of LARR (multivariable analysis)
Adjusted odds ratio
3.86
P < 0.01
W/H ratio · per 0.10 increase
Adjusted odds ratio
2.81
P < 0.01
CF% · per 10% increase
Observational data: associations, not effects.
Further findings
Baseline LA size
- Body size metrics and adiposity measures not independently associated with baseline LA size
LA enlargement 6 months after catheter ablation (CA)
- Higher W/H ratio and CF% groups had persistent LA enlargement vs counterparts
- both P < 0.01
Combined CF% and W/H ratio
- Complementary risk stratification for persistent LA enlargement
