Ivabradine for the treatment of chronic heart failure
Bibliographic record
Abstract
Several studies have underlined the beneficial effects of a lower heart rate on mortality in patients with chronic heart failure and reduced ejection fraction. In clinical practice, achieving a heart rate ≤70 bpm with beta-blockers is not always possible. In this context, the more recent guidelines added ivabradine to the management of those patients if heart rate remains ≥70 bpm in sinus rhythm and symptoms persist despite treatment with an evidence-based or maximum tolerated dose of a beta-blocker, an angiotensin converting enzyme inhibitor or angiotensin-receptor blocker, and a mineralocorticoid receptor antagonist. Ivabradine is a well-tolerated, safe and effective treatment option with the objective to improve prognosis, left ventricular structure and function, exercise tolerance and quality of life. Accordingly, the following article will evaluate the benefits of a combination of the currently recommended pharmacological therapy in chronic heart failure with the selective heart rate reducing agent ivabradine.

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.
