Abstract
Objective To analyze 274 patients underwent off-pump coronary artery bypass grafting surgery(OPCAB)in order to summarize surgical techniques and clinical outcome.Methods 274 patients underwent off-pump CABG(OPCAB) were collected and retrospectively analyzed.196 patients were male and 78 patients were female.Age range was 45-80(average 70.5±5.7).19 patients had single vessel disease.54 patients had twi-vessels disease.201 patients had triple vessels disease.36 patients had left main stem stenosos.Results All of the 274 patients underwent off-pump CABG(OPCAB).The average graft was 3.14 per case.One patient(0.36%) with left main stem stenosis was transferred to on-pump CABG.IABP was used in 4(1.46%) patients preoperative.There were 196 patients(71.5%) left operation room without using dopamine.only 78 patients(28.5%) left with using it.The respirator was used 4-108 hours(average time 8±5.5).The average chest drainage and blood transfusion were(415±260)ml and(260±107) ml.The average ICU and hospital stay were(1.8±0.8)d and(14.8±5.5)d.The operative mortality was 11(4.01%).There are 57 patients had mental symptom after operation without stroke.Infection appeared in 59 patients(21.5%).Atrial fibrillation appeared in 77 patients(28.1%).5 of the all survival patients had symptoms of angina during the follow-up(0-96 months).There were 223(94.5%)of 236 patients over 6 months follow-up without using nitroglycerin.Only 13(5.5%) needed it.Conclusion OPCABG is safe,cost-effective,and suitable for patients with high risk of extracorporeal circulation.

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.
