Atrial Structural Remodeling as an Antiarrhythmic Target
Bibliographic record
Abstract
Atrial fibrillation (AF) is the most common clinically encountered arrhythmia. Conventional pharmacological antiarrhythmic approaches suffer from poor efficacy and risk of serious complications, particularly proarrhythmia. More recently, the notion of "upstream" therapy, targeting the processes involved in the development of the substrate that supports AF, has increasingly become the focus of attention. Many clinical conditions associated with AF are characterized by prominent atrial fibrosis, and pharmacological strategies targeted at the fibrotic substrate itself may aid in the management of AF. Experimental and clinical data suggest that there exists an interplay among angiotensin II-related signaling, inflammation, and oxidative stress in the pathogenesis of AF-promoting structural remodeling, and these processes have become of particular therapeutic interest. This review will highlight pharmacologic approaches that have shown promise for attenuating structural remodeling to achieve antiarrhythmic efficacy in AF.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
