Abstract
Rate of resistance to aspirin and clopidogrel was assessed in 44 patients with non ST elevation acute coronary syndrome. Platelet aggregation was studied by method of Born. Criterion of resistance to aspirin was arachidonic acid induced aggregation > or =20%. Patients with lowering of ADP induced aggregation < 10%, 10 - 29% and 30% relative to initial level were considered resistant, partially resistant, and sensitive to therapy with clopidogrel, respectively. It was shown that rate of resistance to aspirin, clopidogrel, and both drugs reached 25.7, 17.1, and 5.7%, respectively.
