Prasugrel vs Clopidogrel for Acute Coronary Syndromes without Revascularization TRILOGY ACS Roe MT et al. N Engl J Med 2012 ; 367:

Méthodes Objectif Comparaison de 2 AAP, le prasugrel et le clopidogrel, en association avec l’aspirine (100 mg/j) pour le traitement des syndrome coronaires aigus ST- traités médicalement (non revascularisés) Etude Étude prospective, randomisée, double insu, multicentrique, internationale. Critères d’inclusion Syndrome coronaire aigu sans sous décalage de ST TRILOGY ACS Roe MT et al. N Engl J Med 2012 ; 367:

Schéma de l’étude Critère principal de jugement Mortalité CV, IDM, AVC à 30 mois (<75ans) SCA ST- non revascularisé (n = 9326) < 75 ans = 7243 ≥ 75 ans = 2083 R Prasugrel * + Aspirine 100mg/jour Clopidogrel 75mg/jour + Aspirine 100mg/jour Suivi médian : 17 mois * Selon âge et poids : 10 mg (< 75 ans + ≥ 60 kg) 5 mg (≥ 75 ans ou < 75 ans + < 60 kg) TRILOGY ACS Roe MT et al.

Conclusion Après 2,5 ans de suivi pour les patients de moins de 75 ans traités exclusivement de façon médicale à l’occasion d’un SCA ST-, le prasugrel n’apporte pas de bénéfice supplémentaire par rappoprt au clopidogrel. L’utilisation du prasugrel ne s’accompagne pas d’un surcroît statistiquement significatif d’hémorragies. TRILOGY ACS Roe MT et al. N Engl J Med 2012 ; 367:
