Outcomes of patients with heart failure with preserved ejection fraction undergoing catheter ablation of atrial fibrillation.

ABSTRACT:

Background

Limited real-world data exist on early outcomes in patients with heart failure with preserved ejection fraction (HFpEF) undergoing atrial fibrillation (AF) ablation.

Objectives

The purpose of this study was to examine and compare rates of index procedural complications and 30-day readmissions after AF ablation in patients with HFpEF, with heart failure with reduced ejection fraction (HFrEF), and without heart failure.

Methods

Using the Nationwide Readmissions Database (NRD), we examined 50,299 admissions of adults with heart failure undergoing AF catheter ablation between 2010 and 2014. Using ICD-9-CM codes, we identified procedural complications and causes of readmission after AF ablation.

Results

From 2010 to 2014, the prevalence of HFpEF among pat
