Abstract
Refractory angina is a condition where the patient suffers from symptomatic objective ischaemia with Canadian Cardiovascular Society CCS functional class III or IV. Symptoms often continue despite maximum medical and interventional therapy to attempt revascularization or patients do not tolerate the standard treatments. Spinal Cord Stimulation is one of the possible treatments for this disease and is used with relative safety. Randomized controlled trials have shown efficacy for quality of life, exercise tolerance and reduced nitrate consumption. Prospective observational studies have shown long term reduction in hospital admission. Cost reduction in terms of health utilization has been demonstrated in a retrospective study (4). Postulated mechanisms of actions are reduction in pain, sympathetic tone, myocardial oxygen consumption and increased microcirculation (5). There are many challenges in the use of SCS for refractory angina in the areas of suitability, funding, surgical technique, programming and patient acceptance. In this presentation some of these challenges and the recent developments in the field of

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
