Brief summary
Antiplatelet therapy is critical in the management of coronary artery disease.For patients undergoing off-pump coronary artery bypass graft,controversy remains regarding the safety of preoperative antiplatelet therapy.And there is little study about the effect of continuing aspirin until the surgery day on graft patency.So we would like to perform this study to evaluate the effects of preoperative aspirin on graft patency and cardiac events in off-pump coronary bypass.
Interventions
aspirin 100mg daily until the surgery day

Eligibility
Inclusion criteria
* Patients undergoing elective, off-pump coronary artery bypass with at least two grafts * patient able to give informed consent
Exclusion criteria
* on-pump CABG * combined with the valve surgery * Preoperative use of clopidogrel and warfarin * allergy to aspirin * History of severe liver disease * History of bleeding diathesis,significant GI bleed * Patient has known renal failure or contraindication for Cardiac CT Angio * Redo CABG
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| graft patency examined by CT scan | one week after surgery | we would like to compare the graft patency within the one week after the surgery between the preoperative aspirin use and preoperative nonuse.We just want to know wether preoperative aspirin use could improve the graft patency in off-pump coronary artery bypass. |
Secondary
| Measure | Time frame |
|---|---|
| Bleeding, transfusion, re-exploration | perioperative |
