New pharmacotherapy for heart failure with reduced ejection fraction
Bibliographic record
Abstract
INTRODUCTION: The European Society of Cardiology (ESC), Canadian Cardiovascular Society, and the American College of Cardiology Heart Failure (HF) guidelines all currently recommend the use of Angiotensin Converting Enzyme (ACE) inhibitors or Angiotensin Receptor Blockers (ARBs) and Beta Blockers (BB) in the treatment of HF with a reduced ejection fraction (HFrEF). Newer medications targeting combining an ARB with a neprilysin inhibitor (ARNI) sacubitril/valsartan have shown benefits in mortality and can be used in place of an ACE inhibitor or an ARB. Additionally, dapagliflozin, a medication targeting the sodium-glucose cotransporter 2 (SGLT2) can be used in addition to current therapies. AREAS COVERED: This review provides a comprehensive analysis of the evidence around the new pharmacotherapies for HFrEF, specifically, sacubitril/valsartan and dapagliflozin. A comprehensive review of the literature using keywords such as heart failure with reduced ejection fraction, angiotensin receptor, neprilysin inhibitor, and sodium glucose transporter was conducted within the National Centre for Biotechnology Information (NCBI) and Google Scholar databases. The reference sections of articles were also examined to find additional articles. EXPERT OPINION: Sacubitril/valsartan and dapagliflozin both show marked benefits on mortality in HFrEF patients. More research needs to be conducted on the mechanisms of action on disease modification.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
