The effect of restoring sinus rhythm by pulmonary vein isolation (PVI) on the quality of life (QOL) of patients with persistent atrial fibrillation (PerAF) has not been adequately investigated. This study was performed to compare the changes in QOL after extended PVI between patients with PerAF and paroxysmal AF (PAF).

Patients with PAF (n = 38) and PerAF (n = 22) who underwent their first PVI and developed no AF recurrence 6 months after PVI were enrolled. QOL surveys were performed at baseline and 6 months post-ablation using Short Form-36 surveys.

The mental component summary score (MCS) (53.4 ± 10.2 to 56.5 ± 7.1, P = 0.019) and physical component summary score (PCS) (46.1 ± 10.6 to 48.5 ± 8.3, P = 0.015) improved after PVI in the PAF group. The PCS, but not the MCS, improved after PVI in the PerAF group (45.8 ± 7.9 to 51.5 ± 6.2, P < 0.001). Changes in the PCS were greater in the PerAF group than in the PAF group (8.6 ± 6.9 versus 2.8 ± 5.2, P = 0.009). Multivariate regression analysis demonstrated that a low baseline MCS and the type of AF (PAF) were independent predictors of an increased MCS and that a low baseline PCS and the type of AF (PerAF) were independent predictors of an increased PCS.

The changes in QOL differed between PAF and PerAF after PVI. Although most patients with PerAF were asymptomatic before PVI, their improvement in physical QOL was greater than that in patients with PAF. Such beneficial effects on physical QOL are likely expected in patients with PerAF with a low PCS before PVI.
