BACKGROUND In patients on dual antiplatelet therapy with aspirin and clopidogrel, the adjunctive use of cilostazol is associated with enhanced platelet inhibition. However, if cilostazol exerts different pharmacodynamic (PD) effects according to levels of on-treatment platelet reactivity remains unknown. This study aimed to determine the PD effects of(More)
BACKGROUND Several studies have shown that patients with diabetes mellitus (DM) exhibit an impaired response to clopidogrel. This may contribute to their increased risk of recurrent atherothrombotic events, despite the use of dual-antiplatelet therapy. The mechanisms for impaired clopidogrel response in DM patients have not been fully elucidated. (More)
Patients with type 2 diabetes mellitus (T2DM) have impaired clopidogrel-induced antiplatelet effects, which may be in part attributed to their reduced sensitivity to insulin and consequently, results in upregulation of the P2Y12 signalling pathway. It has been hypothesised that insulin sensitising strategies may enhance clopidogrel-mediated P2Y12 inhibitory(More)
Dual antiplatelet therapy--the combination of aspirin and a P2Y12-receptor inhibitor--is the cornerstone of treatment of patients with acute coronary syndromes (ACS) and of those undergoing percutaneous coronary intervention. Prasugrel and ticagrelor have more prompt, potent, and predictable antiplatelet effects than those of clopidogrel, and result in(More)
OBJECTIVES The goal of this study was to assess the pharmacokinetic (PK) and pharmacodynamic (PD) profiles of escalating ticagrelor loading dose (LD) regimens in primary percutaneous coronary intervention (PPCI). BACKGROUND Patients with ST-segment elevation myocardial infarction undergoing PPCI frequently have suboptimal platelet inhibition in the early(More)
Dual antiplatelet therapy with aspirin and an oral ADP P2Y12 receptor antagonist is the standard-of-care for the prevention of ischemic events in patients with acute coronary syndrome or undergoing percutaneous coronary intervention (PCI). However, currently available ADP P2Y12 receptor antagonists have several limitations, such as interindividual response(More)
The University of Florida (UF) Health Personalized Medicine Program launched in 2012 with CYP2C19 genotyping for clopidogrel response at UF Health Shands Hospital. We have since expanded CYP2C19 genotyping to UF Health Jacksonville and established the infrastructure at UF Health to support clinical implementation for five additional gene-drug pairs:(More)
Antiplatelet therapy is the cornerstone of treatment in preventing ischemic events in patients with coronary artery disease (CAD), particularly in the setting of acute coronary syndromes and percutaneous coronary interventions. However, antiplatelet therapy is also associated with an increased risk of bleeding complications, which are more frequent with the(More)
Patients with diabetes mellitus (DM) are at high risk for several cardiovascular disorders such as coronary heart disease, stroke, peripheral arterial disease, and congestive heart failure. DM has reached epidemic proportions and its strong association with coronary artery disease is responsible for increased cardiovascular morbidity and mortality. DM(More)
