YES
To evaluate in-stent protrusion volume evaluated by optical coherence tomography (OCT) 14 days after undergoing primary-PCI with stenting in patients with ST-segment elevation myocardial infarction who receive prasugrel or clopidogrel
Efficacy
Confirmatory
Pragmatic
Phase IV
In-stent protrusion volume with stent-length correction, evaluated by OCT 14 days after primary PCI
*Median variation of in-stent protrusion volume evaluated by OCT
* Median PRU value (or % inhibition) assessed with VerifyNow-P2Y12 assay 1 hour after a loading dose of prasugrel or clopidogrel
* Median variation of PRU value (or % inhibition) using with VerifyNow-P2Y12 assay during treatment period
* Median variation of AUC (or occlusion time) evaluated with T-TAS system during treatment period
* Frequency of 30-day adverse cardiovascular events (including all-cause death, re-infarction, heart failure, target vessel revascularization, stent thrombosis)

Treatment
Medicine |
Patients were randomly assigned by computer-generated randomization sequence to receive prasugrel. Prasugrel treatment was started with a loading dose of 20mg orally before stent implantation, followed by a maintenance dose of 3.75mg once daily (2.5mg once daily for patients with high risk of hemorrhagic complication) in addition to aspirin 100mg once daily for at least 30 days.
Patients were randomly assigned by computer-generated randomization sequence to receive clopidogrel. Clopidogrel treatment was started with a loading dose of 300mg orally before stent implantation, followed by a maintenance dose of 75mg once daily (50mg once daily for patients with high risk of hemorrhagic complication) in addition to aspirin 100mg once daily for at least 30 days.
