Left atrial low voltage areas and heart failure in patients with atrial fibrillation: Implication of the atrial myopathy.
Observational study in ESC heart failure, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
aimsAtrial fibrillation (AF) and heart failure (HF) affect each other and are often co-morbid. The fact that HF development is not uncommon even after ablation suggests that we need a deeper understanding of the pathology of these conditions. Atrial myocardial degeneration is an underlying factor in AF patients and may be associated with HF development after ablation. This study aimed to investigate the impact of low-voltage areas (LVAs) on HF prognosis after AF ablation. METHODS AND
resultsThis observational study included 1481 consecutive patients undergoing initial ablation for AF. Left atrial LVAs were defined as regions with a bipolar peak-to-peak voltage of <0.50 mV. Patients were divided into three groups: no LVA (LVA size indexed to body surface area <3 cm
conclusionsLVA presence and its extent were associated with frequent HF hospitalization and death. Underlying atrial myopathy appears to define a poor HF prognosis after AF ablation.
