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.

Condition Intervention Phase
Coronary Artery Disease Off-pump Coronary Artery Bypass Aspirin Drug: aspirin Phase 3

Further study details as provided by Chinese Academy of Medical Sciences, Fuwai Hospital:

Primary Outcome Measures:
  • graft patency examined by CT scan [ Time Frame: 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 Outcome Measures:
  • Bleeding, transfusion, re-exploration [ Time Frame: perioperative ]

Estimated Enrollment: 200
Study Start Date: March 2010
Estimated Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: preoperative aspirin use Drug: aspirin
aspirin 100mg daily until the surgery day
No Intervention: preoperative aspirin nonuse Drug: aspirin
aspirin is stopped 5-7 days before operation
