Implication
AF ablation success appears comparable across BMI groups; observational data leaves open need for randomized confirmation.
Structured PICO
Does catheter ablation improve freedom from atrial fibrillation and quality of life in obese patients with symptomatic, medication-refractory atrial fibrillation?
P
Population
523 consecutive patients with symptomatic, medication-refractory atrial fibrillation, grouped by body mass index (lean, < 25 kg/m2; overweight, 25 to 29.9 kg/m2; obese, >= 30 kg/m2)
I
Intervention
Catheter ablation
C
Comparator
Lean (BMI < 25 kg/m2) and overweight (BMI 25 to 29.9 kg/m2) patients
O
Outcome
Freedom from atrial fibrillation without the use of antiarrhythmic agents at 12 months
Catheter ablation is an effective treatment for atrial fibrillation in obese patients, yielding similar arrhythmia-free survival and quality of life improvements as seen in lean patients.
