Prognostic Value of a High On-Clopidogrel Treatment Platelet Reactivity in Bivalirudin Versus Abciximab Treated Non–ST-Segment Elevation Myocardial Infarction Patients: ISAR-REACT-4 (Intracoronary Stenting and Antithrombotic Regimen: Rapid Early Action for Coronary Treatment-4) Platelet Substudy

Study Questions:

What is the relevance of high on-clopidogrel treatment platelet reactivity (HPR) in non–ST-segment elevation myocardial infarction (NSTEMI) patients that received abciximab with unfractionated heparin (UFH) or bivalirudin during percutaneous coronary intervention (PCI)?
