Abstract
The purpose of the present study was to analyze the effects of transmyocardial laser revascularization (TMLR) on myocardial perfusion. The value of (99m)Tc-MIBI scintigraphy in the detection of changes in perfusion of the lased and nonlased segments was assessed as well. In 15 patients before TMLR and then 3 and 6 months afterwards, MIBI scintigraphy and a stress test were carried out. At the beginning of the study, all patients were classified as having angina pectoris class III or IV (according to the criteria of the Canadian Cardiac Society); their ejection fraction was >30%. The parameters of the stress test increased significantly in 70% of the patients. Cardiac scintigraphy revealed improved perfusion of 33.7% of the transient defects within 3 months after TMLR which persisted at 6 months with a clear trend towards further improvement in the lased segments. TMLR has been found to be particularly beneficial in patients in whom other invasive methods of treatment cannot be applied.

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 it
