Aspirin and clopidogrel resistance.
Aspirin and clopidogrel provide significant clinical benefit in patients with cardiovascular disease. However, given the complexity of platelet activation, it is not surprising that aspirin or clopidogrel prevent a small proportion of cardiovascular events. Of late, the terms aspirin and clopidogrel "resistance" have entered the physicians' lexicon, and infer a lack of therapeutic response and ...
متن کاملThe antithrombotic profile of aspirin. Aspirin resistance, or simply failure?
Introduction Cyclooxygenase-1 [COX-1, prostaglandin synthase] catalyses the transformation of arachidonic acid to the unstable intermediate prostaglandin PGH2. Subsequently, thromboxane synthase acts on PGH2 to form TXA2, a transient biological product that induces platelet aggregation and is a powerful vasoconstrictor. Aspirin acts primarily by interfering with the biosynthesis of cyclic prost...
متن کاملAspirin and clopidogrel resistance: methodological challenges and opportunities
Antiplatelet drug resistance is one of the urgent issues in current cardiovascular medicine. Many platelet function tests have been used to define responsiveness of patients with cardiovascular disease to aspirin and clopidogrel. In most studies, cut-off values of platelet function tests for defining responsiveness to antiplatelets were chosen arbitrarily. Different tests provided wide-ranging ...
متن کاملAspirin and Clopidogrel Resistance in Drug Eluting Stent Era
Platelets play a central role in the pathogenesis of atherothrombosis. Dual antiplatelet therapy with clopidogrel plus aspirin has been shown to reduce ischemic events in patients undergoing percutaneous coronary intervention (PCI) and stenting. Although dual antiplatelet therapy reduces the risk of cardiovascular episodes after PCIs, a substantial number of incidents continue to occur. Many ca...
متن کاملAspirin and clopidogrel resistance: an emerging clinical entity.
Antiplatelet therapy is a cornerstone of cardiovascular medicine. Aspirin and clopidogrel have emerged as critical therapies in the treatment of cardiovascular disease. Despite their efficacy, patients on these medications continue to suffer complications. Millions of patients are currently on low-dose antiplatelet therapy but it is unknown how many of these patients are under-treated or on the...
