UNLABELLED We evaluated the response to clopidogrel among aspirin-resistant versus aspirin-sensitive patients undergoing elective coronary stenting. Patients (n = 150) treated with aspirin but not clopidogrel had blood samples drawn at baseline and 24 h after clopidogrel loading. Depending on the definition used, 9% to 15% were resistant to aspirin and 24%(More)
CONTEXT Clinical trials that have excluded patients at high risk for cardiac events have led to commercial labeling approval of drug-eluting stents; nevertheless, such high-risk patients commonly undergo stent placement in clinical practice. The degree to which they experience cardiac events at a higher rate than non-high-risk patients is unclear. (More)
Asian Indians are reported to have higher mortality and morbidity from coronary artery disease (CAD) than other ethnic groups. This variation in events cannot be explained only by differences in conventional risk factors. Platelet activation is an important factor in the pathogenesis of CAD, however, there are limited data concerning platelet reactivity in(More)
BACKGROUND Clinical trials have shown drug-eluting stents (DES) to be superior to bare metal stents (BMS) in preventing in-stent restenosis and target vessel revascularization. Although these results have ushered in a sea change in the practice of myocardial revascularization, important questions remain unanswered concerning rates of ischemic complications(More)
BACKGROUND The direct thrombin inhibitor bivalirudin has previously been associated with better efficacy and lower hemorrhage risk than heparin during balloon angioplasty. This agent has not yet been tested with stenting or in combination with platelet glycoprotein IIb/IIIa antagonists. METHODS AND RESULTS In a pilot trial, 268 patients who underwent(More)
OBJECTIVE The study was done to determine whether eptifibatide, a platelet glycoprotein (GP) IIb/IIIa antagonist, prevents ischemic complications following percutaneous coronary interventions (PCIs) in women as well as in men. BACKGROUND Eptifibatide reduces ischemic complications after nonurgent coronary stent interventions. METHODS We compared(More)
BACKGROUND Although cardiac troponin (cTn) elevation is associated with periprocedural complications during percutaneous coronary intervention (PCI) in the setting of acute coronary syndromes, the prevalence and prognostic significance of preprocedural cTn elevation among patients with stable coronary artery disease undergoing PCI are unknown. METHODS AND(More)
BACKGROUND Recent case control studies suggest that patients with subacute stent thrombosis (SAT) have increased platelet reactivity. However, SAT often presents as acute myocardial infarction (AMI), which is also associated with augmented platelet activation. We therefore compared platelet reactivity in patients with SAT and patients with AMI unrelated to(More)
BACKGROUND Because of the adverse characteristics associated with heparin, direct antagonists of thrombin have been investigated as anticoagulants during percutaneous coronary interventions. However, the hematologic and clinical interactions between direct thrombin antagonists and inhibitors of platelet glycoprotein IIb-IIIa are incompletely explored. (More)
Ticlopidine and abciximab are two antiplatelet agents that are frequently administered during percutaneous coronary interventions. Although they have different mechanisms of action and pharmacological profiles, the two agents are often concomitantly used in complicated stent placements. The purpose of the study was to evaluate the effect of ticlopidine(More)
