Evidence that pre-existent variability in platelet response to ADP accounts for 'clopidogrel resistance': a rebuttal.

BACKGROUND Clopidogrel is a widely used antithrombotic agent that inhibits the platelet P2Y(12) adenosine diphosphate (ADP) receptor. There is increasing interest in 'clopidogrel resistance'. OBJECTIVES To determine whether 'clopidogrel resistance' is accounted for by a pre-existent variability in platelet response to ADP. METHODS Platelet response to 20 microm ADP was analyzed by four inde...

Clopidogrel for coronary stenting: response variability, drug resistance, and the effect of pretreatment platelet reactivity.

BACKGROUND Clopidogrel is administered to prevent stent thrombosis; however, the uniformity of platelet inhibition after treatment and the influence of pretreatment reactivity on drug response have not been described. METHODS AND RESULTS Platelet aggregation (5 and 20 micromol/L ADP), the activation of glycoprotein IIb/IIIa (PAC-1 antibody), and the expression of P-selectin were measured in p...

Variability in platelet responsiveness to clopidogrel among 544 individuals.

OBJECTIVES We sought to describe the responses of patients to clopidogrel using ex vivo measures of platelet aggregation and activation in a large, heterogeneous population. BACKGROUND Recently, a number of reports, using various definitions, have dichotomized patients who are treated with clopidogrel into a minority of "non-responders" and a majority of "responders." Such classifications imp...

Options to overcome clopidogrel response variability.

Oral antiplatelet agents targeting the platelet P2Y12 receptor are an integral component of treating patients with acute coronary syndrome and those undergoing percutaneous coronary intervention. Clopidogrel has been the most commonly used agent in this respect worldwide. However, there are certain shortcomings of clopdiogrel, the most important of which is the wide response variability of plat...

Adrenoreceptors, platelet reactivity and clopidogrel resistance.

Thromb Haemost 2008; 100: 729–730 Platelet activation plays a central role in haemostasis and thrombosis. Antiplatelet therapy is considered to be the ‘cornerstone’in the prevention and treatment of thrombotic diseases such as coronary artery disease (CAD), stroke and peripheral arterial disease (PAD). While dual antiplatelet therapy with aspirin and clopidogrel is currently the standard therap...
