Association Between Diagnosis-to-Ablation Time and Postablation Outcomes in Older Patients With Persistent Atrial Fibrillation.

ABSTRACT:

Background

The relationship between the timing of catheter ablation and post-ablation outcomes in older patients with persistent atrial fibrillation (AF) remains uncertain.

Objectives

This study aimed to investigate whether diagnosis-to-ablation time (DAT) influences post-ablation outcomes in older patients with persistent AF.

Methods

From January 2020 to December 2022, 587 patients were stratified into 2 groups: the early ablation group (DAT ≤12 months, n = 332) and the late ablation group (DAT >12 months, n = 255) based on DAT. The study outcomes included freedom from atrial arrhythmia (AA) recurrence and adverse cardiovascular outcomes (death, cardiovascular hospitalization, ischemic stroke, and a composite outcome comprising all 3 outcomes).
