E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the inhibition of platelet aggegation in the early phase of primary PCI (i.e. 30 minutes after star of treatment as primary study endpoint). |
Valutare l’inibizione dell’aggregazione piastrinica in fase precoce dell’angioplastica primaria (l’endpoint primario è a 30 minuti dopo l’inizio del trattamento). |
|
E.2.2 | Secondary objectives of the trial |
To assess the inhibition of platelet aggegation up to 6 hours after the treatment; pharmacokynetic evaluation (dosage of the active prasugrel metabolite) in patients of the prasugrel group (chewed tablets compared to whole tablets); evaluation of adverse clinical events in all patients and evaluation of alterations (extension of myocardial and microvascular damage) to cardiac magnetic resonance in patients who will provide consent to participate in this sub-study. |
Valutare l’inibizione dell’aggregazione piastrinica fino a 6 ore dopo il trattamento; valutazione farmacocinetica (dosaggio del metabolita attivo del prasugrel) nei pazienti del gruppo prasugrel (compresse masticate rispetto a compresse intere); valutazione degli eventi clinici avversi in tutti i pazienti e valutazione delle alterazioni (estensione del danno miocardico e microvascolare) alla risonanza magnetica cardiaca nei pazienti che forniranno il consenso a partecipare a tale sottostudio |
