Atrial fibrillation recurrence risk after single catheter ablation in patients with history of hyperthyroidism: systematic review and meta-analysis.
Review in The Egyptian heart journal : (EHJ) : official bulletin of the Egyptian Society of Cardiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAtrial fibrillation (AF) is the most common arrhythmias. Other than pharmacotherapy, catheter ablation is preferred especially for symptomatic paroxysmal AF or persistent AF. However, recurrence of atrial fibrillation following catheter ablation can occur due to several factors. Hyperthyroidism is known as a factor in atrial fibrillation pathogenesis but its role in AF recurrence following ablation is not known yet. Therefore, we aimed to assess the recurrence risk after catheter ablation in patients with a history of hyperthyroidism.
methodsSystematic searching was performed through three databases: MEDLINE, EMBASE, and SCOPUS for studies reporting the recurrence of AF (hazard ratio) following catheter ablation in patients with a history of hyperthyroidism. The risk of bias assessment of included studies was performed using quality in prognosis studies (QUIPS). Meta-analysis (random effect model and inverse variance) was conducted using RevMan software version 5.4.
resultsFour studies involving 837 subjects were included. Pooled analysis shows a higher risk of recurrence of atrial fibrillation following catheter ablation in patients with history of hyperthyroidism (HR 1.86 [CI 95% 1.26-2.75]; I
conclusionsHistory of hyperthyroidism was found as the risk of recurrence of atrial fibrillation after a single ablation procedure. Patients with amiodarone-induced hyperthyroidism have a higher recurrence risk. Further studies with larger participants are needed for subgroup analysis on specific parameters of the ablation.
