Treatment of intractable angina in a nonagenarian patient by direct coronary stenting
Bibliographic record
Abstract
BACKGROUND: A 91-year-old man presented with a 6-month history of exertional angina. As he was already on maximally tolerated medical therapy, we decided to perform coronary angiography, which revealed severe stenosis of the distal main stem coronary artery, OUTCOME: The lesion was crossed with an intra-coronary wire, and a stent placed to cover the distal main stem lesion, without prior balloon dilatation. The result was satisfactory and he remains symptom-free at 6-month follow-up. CONCLUSION: Treatment of left main stem lesions with percutaneous intervention may be an acceptable alternative to surgery in high-risk elderly patients. Since percutaneous coronary angioplasty can be performed on very elderly patients with a high degree of success, the decision to investigate and treat should not be based solely on biological age.

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.
