Background
Obesity is an important risk factor for atrial fibrillation (AF), and negatively affects health-related quality of life (QoL) and treatment efficacy. The impact of obesity on the improvement of QoL and on AF recurrence in patients undergoing thoracoscopic AF ablation is unknown.
Purpose
To assess the change in QoL and the risk of AF recurrence in obese and non-obese patients with atrial fibrillation undergoing thoracoscopic ablation
Methods
Patients undergoing thoracoscopic AF ablation were prospectively included. Holters were performed before and at 3, 6, 9 and 12 months after the procedure. AF recurrence was defined as any atrial tachyarrhythmia episode >30 seconds during one year of follow-up. QoL and AF recurrence rate were assessed for normal weight (BMI ≤ 24,9 kg/m2), overweight (25,0 – 29,9 kg/m2) and obese (≥ 30,0 kg/m2) patients. QoL was measured by the Short Form 36 questionnaire at baseline and at one year follow-up.
Results
Four hundred and eight patients were included for analysis. Six out of eight QoL domains scored lower in obese versus non-obese patients before the procedure. In all patients, six out of eight domains increased after the procedure (p<0.01 for most domains). Obese patients showed a larger improvement of emotional related QoL (p=0.01) and a trend towards a larger improvement of mental QoL (p=0.07), while physical QoL increased similarly to non-obese patients (figure). In obese patients, QoL increased similarly for those with and without AF recurrence (p=0.78), whereas in non-obese patients, AF recurrence was associated with less improvement in mental QoL. AF recurrence at 1-year was similar in all groups (normal weight 72.4%, overweight 68%, obese 70.4%, p=0.692).
Conclusion
After thoracoscopic ablation, obese patients have a similar AF freedom rate as non-obese patients, but a greater improvement in mental quality of life, irrespective of AF recurrence status, after thoracoscopic ablation.
