Impact of abdominal obesity on outcomes of catheter ablation in Korean patients with atrial fibrillation.

ABSTRACT:

Background

Effects of abdominal obesity on outcomes of atrial fibrillation (AF) ablation remains ill-defined. Here, we evaluated the impact of abdominal obesity on the long-term efficacy and safety of catheter AF ablation among Korean patients.

Methods

We utilised the Korean National Health Insurance Service database to identify patients who underwent AF ablation. Abdominal obesity was defined as waist circumference ≥90 cm (males) and ≥85 cm (females). The primary endpoint was AF recurrence and secondary endpoints were ischaemic stroke, intracranial haemorrhage and death. Additionally, safety endpoints of peri-procedural complications were studied.

Results

Among 5397 patients (median age 58 [IQR 51-65] years; 23.6% females), abdominal obesity was present in 1759 (32.6
