[Clinical outcome of patients after transmyocardial laser revascularization alone and combined with coronary artery bypass grafting].
Bibliographic record
Abstract
The aim of the study was to assess the effect of transmyocardial laser revascularization (TMLR) alone and in combination with coronary artery bypass grafting (CABG) on the angina score (CCS--Canadian Cardiovascular Society class), exercise tolerance and left ventricular function 6 months after the procedures. Sixty two patients were subjected to revascularization, 38 to sole TMLR procedure and 24 to combination CABG and TMLR (CABG/TMLR group). The angina score and exercise stress test together with radionuclide ventriculography were performed before and 6 months after the operation. The angina class and exercise tolerance were similar in both groups preoperatively. After the operation the improvement was seen in both groups with no statistical difference. The left ventricular ejection fraction were 61 +/- 8% and 54 +/- 8% (p < 0.05) before operation and after 6 months respectively. Transmyocardial laser revascularisation alone and in combination with coronary artery bypass grafting may relieve the angina and improve the exercise tolerance. However the left ventricular ejection fraction may drop significantly.

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.
