Relief of Refractory Angina With Vericiguat
Bibliographic record
Abstract
BACKGROUND: Refractory angina represents a challenging clinical symptom, with limited therapeutic options beyond conventional antianginal therapy and revascularization. CASE SUMMARY: A 43-year-old man with a history of hypertension, diabetes mellitus, and coronary atherosclerotic heart disease presented with persistent angina pectoris, classified as Canadian Cardiovascular Society class IV, despite being on optimized antianginal therapy including calcium-channel blockers, nitrates, and other adjunctive medications. His Seattle Angina Questionnaire score was 12.61. Introduction of vericiguat 10 mg daily resulted in marked symptom improvement, with Seattle Angina Questionnaire score increasing to 57.35 and angina classification improving to class II. DISCUSSION: This represents to our knowledge the first documented use of vericiguat for refractory angina. Vericiguat stimulates soluble guanylate cyclase and enhances cyclic GMP production, improving endothelial dysfunction and impaired vasodilation; this may be the mechanism by which it relieves refractory angina. TAKE-HOME MESSAGES: Vericiguat may offer therapeutic benefit in refractory angina patients unresponsive to conventional therapy. Further investigation is warranted.

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.
