Discordance between left atrial pressure and risk scores in assessment of heart failure with preserved ejection fraction in patients with atrial fibrillation undergoing catheter ablation.

ABSTRACT:

Aims

Identifying risk or probability of heart failure with preserved ejection fraction (HFpEF) in patients with atrial fibrillation (AF) is challenging. This study aimed to assess the prevalence and factors associated with elevated left atrial pressure (LAP) in AF patients undergoing catheter ablation and to evaluate the concordance between elevated LAP and HFpEF risk scores.

Methods and results

This study included 336 symptomatic AF patients (median age 65 years, 41% female) undergoing catheter ablation. Elevated LAP was defined as a mean LAP ≥ 15 mmHg. High HFpEF probability was defined by H2FPEF ≥ 6 and/or HFA-PEFF ≥ 5. Elevated LAP was present in 37% (n = 125) of patients, and factors associated with elevated LAP included higher body mass index (BMI; OR 1.21, 95% CI: 1.1
