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.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimsIdentifying 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
resultsThis 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: 1.11-1.31) and lower LA reservoir strain (OR 0.97, 95% CI: 0.94-0.99). General anaesthesia and non-sinus rhythm were linked to higher LAP but not independently; AF type showed no effect. Among 204 eligible patients, 36% had a high HFpEF probability. Over 12 months, AF recurrence (26% vs. 24%, P = 0.775) and repeat ablations (11% vs. 7.2%, P = 0.230) were similar regardless of LAP status, but severe adverse events (death, life-threatening situations, hospitalizations, or persistent disability) were more common in those with elevated LAP (6.7% vs. 1.7%, P = 0.044).
conclusionOver one-third of catheter ablation patients had elevated LAP. Poor agreement between elevated LAP and HFpEF risk scores suggests that using these risk scores may not be advisable in AF population.
