To investigate the biosynthesis of PGD2 during percutaneous transluminal coronary angioplasty (PTCA) procedure.
A) To determine whether biosynthesis of PGD2 is altered in response to vascular injury in humans
B) Patients will be grouped base on their aspirin using status. Three groups of no aspirin but an alternative anti-platelet medicine, low dose (81 mg) aspirin, high dose 325 mg aspirin will be enrolled.
