Assessment of the Response to Antiplatelet Treatment in Cardiovascular Patients With the Optical Aggregometer and PFA-100

Abstract

Many studies have shown that antiplatelet drugs decrease vascular events while some patients experience vascular events despite the antiplatelet treatment. We evaluated the effects of aspirin and clopidogrel on platelet functions and investigated the incidence of antiplatelet drug resistance. The study group consisted of 72 cardiovascular patients using antiplatelet drugs and 22 volunteers. The % maximum aggregation and time to reach maximum aggregation against ADP, collagen and epinephrine were determined. Collagen/Epinephrine and Collagen/ADP cartridges closure times were recorded. Those with platelet functions within the control group limits despite antiplatelet treatment were considered to be resistant to drugs. Aspirin decreased the aggregation response especially against epinephrine and collagen while clopidogrel mainly decreased the aggregation response against ADP. The combined drug group had the lowest maximum aggregation responses. PFA- 100 showed that aspirin increased only Collagen/Epinephrine cartridge's closure times. The incidence of aspirin resistance was 12/37 and clopidogrel resistance was 1/17. We found no association between the PFA-100 and the aggregometer in determining drug resistance. We observed that antiplatelet drugs had various effects on platelets and that the methods used to assess platelet functions did not show correlation with each other.
