Abstract
Atrial fibrillation (AF) is the most common sustained arrhythmia in clinical practice and is associated with morbidity and mortality. Over the past 2 decades, there have been major advances in understanding AF pathophysiology, but important knowledge gaps, particularly about targetable basic mechanisms, remain. Recent metabolomic and proteomic studies have shown changes in the expression of molecules involved in metabolic pathways in human and experimental AF, indicating a role for metabolic alterations in AF pathophysiology. AF is characterized by irregular high-frequency excitation and contraction that affect atrial energy demands, circulation and oxygen supply, and change the balance between metabolic demand and supply, causing metabolic stress. Here, we review the information available about AF-induced metabolic changes and their pathophysiological contribution. We also discuss the possibilities of developing novel therapeutic strategies that act by modulating cardiac metabolic processes during AF.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
