Future Perspectives in the Pharmacological Treatment of Atrial Fibrillation and Ventricular Arrhythmias in Heart Failure
Bibliographic record
Abstract
Heart failure (HF) is a clinical syndrome characterized by significant impairment of cardiac ventricular function. Atrial fibrillation (AF) is the most commonly observed sustained arrhythmia in clinical practice. Both HF and AF are associated with increased morbidity and mortality and their prevalence increases with age. Approximately 50% of patients with moderate HF die due to ventricular fibrillation that leads to sudden cardiac death. Patients with AF exhibit increased mortality due to HF and stroke. HF and AF often co-exist, and the development of the other condition further deteriorates prognosis. Both chronic HF and AF lead to structural and electrophysiological changes in the heart called remodeling, modifying therapeutic targets including those for antiarrhythmic intervention. Current pharmacological treatment of arrhythmias has major limitations due to low efficacy and serious adverse effects. In this review, the main aspects of electrical remodeling in HF and AF are discussed along with possible novel targets identified for future pharmacological antiarrhythmic therapy.

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.
