Chronic heart failure and multiple micronutrient supplementation: realistic hope or idealistic conjecture?
Bibliographic record
Abstract
Recent studies have demonstrated the inefficacy of nutritional supplements containing various combinations of vitamins and minerals for otherwise healthy elderly people and patients with ischemic heart disease. However, patients with chronic heart failure (CHF) have, up until recently, been excluded from such studies. CHF has a high mortality and morbidity and patients are often elderly with poor general nutrition and high levels of micronutrient deficiency. It is in this population that nutritional supplementation has the most potential benefit. Evidence is accumulating that a strategy of long-term highdose multiple micronutrient supplementation might improve symptoms and cardiac function in elderly patients with CHF. In this article, we review the effects of individual micronutrients and how they might impact on CHF, and present recent data that dietary supplementation might offer an addition to standard therapy for CHF.

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.
