To investigate the effect of different dosages of aspirin on platelet aggregation and to determine the possible mechanisms of aspirin resistance, we intend to compare the effects of low, medium dose aspirin with clopidogrel (an alternative antiplatelet agent) in patients after coronary artery bypass surgery.
