Exclusion Criteria:
- Severe valvular heart disease requiring concomitant or staged valvular surgery;
- History of non-skin cancer in the past 3 years;
- Inflammatory bowel disease or chronic diarrhea;
- Neuromuscular diseases or non-transient creatine kinase levels greater than 3 times the upper limit of the normal range (except those associated with myocardial infarction);
- Clinically significant non-transient (At least 2 laboratory tests) blood abnormalities (Hemoglobin <100g/L or hematocrit < 30% or > 52% or white blood cell count < 3×109/L or platelet count < 100×109/L);

Eksperimentel: Colchicine group
Patients are randomized within 3 days after successful isolated CABG, and on the day of randomization, eligible patients receive guideline-directed standard secondary prevention therapy plus colchicine (0.5 mg qd) starting as soon as possible (within 24 hours) and continuing for 24 months.
|
Colchicine 0.5 mg once daily will be given on the basis of guideline-recommended standard secondary prevention therapy after CABG for 24 months.

Placebo komparator: Placebo group
Patients are randomized within 3 days after successful isolated CABG, and on the day of randomization, eligible patients receive guideline-directed standard secondary prevention therapy plus matching placebo (1 tablet qd) starting as soon as possible (within 24 hours) and continuing for 24 months.
|
Placebo one tablet once daily will be given on the basis of guideline-recommended standard secondary prevention therapy after CABG for 24 months.

graft failure rate
Tidsramme: 2 year after randomization
|
At 24 months postoperatively, all patients who complete the study will undergo coronary computed tomographic angiography (CCTA) to assess graft patency, calculated as 1 minus graft failure rate, where graft failure rate = (number of grafts graded B or O according to the Fitzgibbon classification / total number of grafts) × 100%.
