Key result
Plasma lipids and dietary fat intake show no reported link to atrial tachyarrhythmia recurrence.
Why the study?
No previous studies have examined the association between a broad lipid profile and the risk of atrial tachyarrhythmia recurrence after catheter ablation.
Do plasma lipid levels and dietary fat intake influence atrial tachyarrhythmia recurrence in patients undergoing catheter ablation?

Do plasma lipid levels and dietary fat intake influence atrial tachyarrhythmia recurrence in patients undergoing catheter ablation?
Plasma lipid profiles were associated with TAR risk after ablation; these observational data leave open whether targeted lipid changes affect recurrence.
Background/Objectives: Anti-arrhythmic properties have been attributed to several lipids.However, as far as we know, no previous studies have examined the association between a broad lipid profile and the risk of atrial tachyarrhythmia recurrence (TAR).We aimed to analyze the association of both plasma lipid levels and dietary fat intake with the risk of TAR after 18 months of follow-up in patients undergoing catheter ablation in the PREDIMAR (PRevención con DIeta Mediterránea de Arritmias Recurrentes) trial.

Belzunce et al. (2026) conducted a cohort in Atrial tachyarrhythmia. Plasma lipid levels and dietary fat intake was evaluated on Atrial tachyarrhythmia recurrence (TAR). Plasma lipid levels and dietary fat intake associations with atrial tachyarrhythmia recurrence were evaluated, but no results were reported in the provided abstract.
