Bivalirudin/Prasugrel Versus Abciximab/Clopidogrel in Patients Presenting With STEMI
Bivalirudin Plus Prasugrel vs Abciximab Plus Clopidogrel. Optimizing Ischemic Protection and Bleeding Risk in Patients With ST Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention

  • Study Participants

In the setting of ST elevation myocardial infarction newer therapies has been recently studied and, following encouraging results, introduced into the clinical practice. Prasugrel showed to be a valid alternative to overcome limitation of clopidogrel therefore providing a better ischemic protection. On the other hand, bivalirudin is at least as beneficial as heparin/abciximab as anticoagulant agent but associated with fewer hemorrhagic events. The primary hypothesis of the study is that the combination of prasugrel plus bivalirudin can be associated with a better risk/benefit profile.

In the setting of STEMI, adjunctive pharmacological therapy plays a key role in the acute management. Along with the clear benefit of mechanical reperfusion strategies, several drugs showed to be beneficial. On top of clopidogrel, heparins and IIB/IIIa glycoprotein, other drugs have been recently introduced showing encouraging results. These "new" drugs, namely prasugrel and bivalirudin, have only been compared separately.

Primary hypothesis: the combination of prasugrel/bivalirudin is superior to the combination of clopidogrel and heparin/abciximab in terms of net adverse clinical events, i.e. ischemic events plus hemorrhagic events

Drug prasugrel/bivalirudin

60mg loading dose followed by 10mg or 5 mg (according to body weight or age)maintenance dose of prasugrel. Bivalirudin during the primary PCI (bolus plus infusion)

  • Other names: Efient, Angiox

Drug clopidogrel/abciximab

600mg loading dose of clopidogrel followed by 75mg maintenance dose. Abciximab will be used during primary PCI, bolus plus infusion.

  • Other names: Plavix, ReoPro

prasugrel/bivalirudin Active Comparator

60 mg loading dose of prasugrel will be followed by maintenance dose of 10mg (or 5mg according to body weight and age). During primary PCI, Bivalirudin will be used as anticoagulant (bolus plus infusion), on a weight-adjusted dose.

clopidogrel/abciximab Active Comparator

600mg loading dose of clopidogrel will be followed by 75mg maintenance dose. During primary PCI abciximab (bolus plus infusion) will be used as anticoagulant.
