Inclusion Criteria:(A patient will be included in the study when the following criteria and requirements are met)
① Patient age of ≥25 years but ≤85 years, and patients with CAD who require multivessel coronary bypass surgery. ② Angina that affects daily life and work and is uncontrollable with conservative treatment. ③ Significant stenosis in the left main (LM) coronary artery, left anterior descending (LAD) branch or left circumflex (LCX) branch \>70%. ④ Severe stenosis (stenosis degree \>70%) of three main branches of the coronary artery (anterior descending branch, circumflex branch, right coronary artery) with the need to undergo off-pump coronary artery bypass surgery.
Exclusion Criteria:
