Purpose
This is a single-centre, open-label prospective randomized pharmacodynamic investigation of 2 antiplatelet regimens in patients undergoing coronary intervention for ST segment elevation myocardial infarction(STEMI):
- Tirofiban bolus only or bolus followed by 2 hour infusion on top of 600 mg clopidogrel or 60 mg prasugrel.
- Prasugrel given at 60 mg.

Primary Outcome Measures:
- Percentage IPA after 20uMol/ADP at 30' will be superior in the tirofiban arm (as aggregate) versus prasugrel alone arm [ Time Frame: 30 minutes ]Platelet aggregation (PA) will be performed as previously reported [J Am Coll Cardiol 2006;48:2178-85]. Blood samples anticoagulated with 0.129 mol/l sodium citrate will be collected for platelet reactivity. Platelet-rich plasma, obtained by centrifuging whole blood for 10 min at 200 g, will be stimulated with 5 and 20 µmol/l adenosine 5'-diphosphate (ADP) (Alfa Wasserman, Bologna, Italia) and aggregation will be assessed using a AggRAM Advanced Modular System light transmittance aggregometer.
Secondary Outcome Measures:
- Percentage IPA at 15 minutes after ADP or TRAP induced platelet aggregation via traditional light transmission aggregometry. [ Time Frame: 15 minutes ]Blood samples draen at 15', 30', 1H, 2H, 6H and 18-24H, anticoagulated with 0.129 mol/l sodium citrate will be collected for platelet reactivity. Platelet-rich plasma, obtained by centrifuging whole blood for 10 min at 200 g, will be stimulated with 5 and 20 µmol/l adenosine 5'-diphosphate (ADP) and 5 and 15 TRAP.
- Clinical outcomes [ Time Frame: 1 year ]Death, Myocardial infarction, stroke and the need for target vessel revascularisation will be monitored up to 1 year
- Percentage IPA at 1 hour after ADP or TRAP induced platelet aggregation via traditional light transmission aggregometry. [ Time Frame: 1 hour ]Blood samples draen at 15', 30', 1H, 2H, 6H and 18-24H, anticoagulated with 0.129 mol/l sodium citrate will be collected for platelet reactivity. Platelet-rich plasma, obtained by centrifuging whole blood for 10 min at 200 g, will be stimulated with 5 and 20 µmol/l adenosine 5'-diphosphate (ADP) and 5 and 15 TRAP.
- Percentage IPA at 2 hours after ADP or TRAP induced platelet aggregation via traditional light transmission aggregometry. [ Time Frame: 2 hours ]Blood samples draen at 15', 30', 1H, 2H, 6H and 18-24H, anticoagulated with 0.129 mol/l sodium citrate will be collected for platelet reactivity. Platelet-rich plasma, obtained by centrifuging whole blood for 10 min at 200 g, will be stimulated with 5 and 20 µmol/l adenosine 5'-diphosphate (ADP) and 5 and 15 TRAP.
- Percentage IPA at 6 hours after ADP or TRAP induced platelet aggregation via traditional light transmission aggregometry. [ Time Frame: 6 hours ]Blood samples draen at 15', 30', 1H, 2H, 6H and 18-24H, anticoagulated with 0.129 mol/l sodium citrate will be collected for platelet reactivity. Platelet-rich plasma, obtained by centrifuging whole blood for 10 min at 200 g, will be stimulated with 5 and 20 µmol/l adenosine 5'-diphosphate (ADP) and 5 and 15 TRAP.
- Percentage IPA at 18-24 hours after ADP or TRAP induced platelet aggregation via traditional light transmission aggregometry. [ Time Frame: 18-24 hours ]Blood samples draen at 15', 30', 1H, 2H, 6H and 18-24H, anticoagulated with 0.129 mol/l sodium citrate will be collected for platelet reactivity. Platelet-rich plasma, obtained by centrifuging whole blood for 10 min at 200 g, will be stimulated with 5 and 20 µmol/l adenosine 5'-diphosphate (ADP) and 5 and 15 TRAP.

Detailed Description:
Primary hypothesis: Percentage IPA after 20uMol/ADP at 30' will be superior in the tirofiban arm (as aggregate) versus prasugrel alone arm Percentage IPA at 30' after 20uMol/ADP 90%±15 and 80%±15 in the tirofiban and prasugrel alone arm, respectively. For a power of 90% and an alpha error set at 5%, 50 patients per group have to be recruited.
