The therapeutic potential of angiotensin II receptor blockers in the treatment of heart failure
Bibliographic record
Abstract
In clinical heart failure (HF) the renin-angiotensin-aldosterone system is an important component of neurohormonal activation. Angiotensin-converting enzyme inhibitors have been shown to be of great clinical benefit in reducing the production of angiotensin II. However, they do not fully suppress angiotensin II production in HF because there are other pathways through which angiotensin II can be produced. Theoretically, angiotensin II receptor blockers (ARBs) have great potential because of their ability to directly block angiotensin II produced through any pathway. A large body of literature has accumulated examining the effects of ARBs in HF. The earlier, smaller studies examined outcomes such as symptoms, neurohormonal concentrations and cardiac function. More recent, larger studies have examined the effects of ARBs on mortality and morbidity. This paper reviews the data defining the role of ARBs in the treatment of HF patients, focusing more on the large randomised clinical outcome trials.

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.
