Interventions/Control_1

Patients with ACS were randomly assigned to clopidogrel (loading/maintenance dose: 300/75 mg) or prasugrel (20/3.75 mg). Aspirin (200/100 mg) was administered in both groups. We evaluated the platelet aggregation at baseline, 0.5-1.0 hours, 2-4 hours, 6-12 hours and 18-24 hours after the loading dose, using T10 (time to reach 10 kPa from baseline) and AUC10 (area under the flow pressure curve for 10 min). T10 represented the onset of platelet thrombus formation and AUC10 represented total thrombogenicity.

Interventions/Control_2

Patients with ACS were randomly assigned to clopidogrel (loading/maintenance dose: 300/75 mg) or prasugrel (20/3.75 mg). Aspirin (200/100 mg) was administered in both groups. We evaluated the platelet aggregation at baseline, 0.5-1.0 hours, 2-4 hours, 6-12 hours and 18-24 hours after the loading dose, using T10 (time to reach 10 kPa from baseline) and AUC10 (area under the flow pressure curve for 10 min). T10 represented the onset of platelet thrombus formation and AUC10 represented total thrombogenicity.
