Measure
Active Colchicine
On the day of surgery, the intervention group will receive 2 doses of colchicine 0.6 mg orally. The first dose will be administered within 4 hours before surgery. The second dose will be given between 6:00PM and 11:59PM after surgery. All patients will receive colchicine 0.6 mg or placebo twice daily orally for 10 days. Colchicine
Placebo Colchicine
On the day of surgery, the intervention group will receive 2 doses of colchicine placebo 0.6 mg orally. The first dose will be administered within 4 hours before surgery. The second dose will be given between 6:00PM and 11:59PM after surgery. All patients will receive colchicine 0.6 mg or placebo twice daily orally for 10 days. Colchicine Placebo

SECONDARY outcome

Timeframe: Post-operative Day 1 until Postoperative Day 30

Requires one of the following criteria: A) Elevated troponin or CK-MB measurement with one or more of the following defining features: 1. Ischemic signs or symptoms (i.e., chest, arm, neck, or jaw discomfort; shortness of breath, pulmonary edema); 2. Development of pathologic Q waves present in any two contiguous leads that are \>30 milliseconds; 3. Electrocardiogram (ECG) changes indicative of ischemia (i.e., ST segment elevation \[\>2 mm in leads V1, V2, or V3 OR \>1 mm in the other leads\], ST segment depression \[\>1 mm\], OR symmetric inversion of T waves \>1 mm) in at least two contiguous leads; 4. New LBBB; or v. new or presumed new cardiac wall motion abnormality on echocardiography or new or presumed new fixed defect on radionuclide imaging; B) Elevated troponin measurement after surgery with no alternative explanation (e.g., pulmonary embolism, sepsis) to myocardial injury
