Prise en charge des AI/NSTEMI
• Stratification du risque
• Traitement anti-ischémique : β-bloquant, dérivés nitrés et antagonistes calciques
• Traitement antiagrégant plaquettaire adapté selon le risque initial
- Aspirine + clopidogrel chez tous les patients dans la mesure où il n’y a pas de contre-indication
- Anti-GPIIb/IIIa pour les patients à risque intermédiaire ou à haut risque
• Traitement anticoagulant recommandé chez tous les patients en association au traitement antiagrégant plaquettaire
• Revascularisation pour les patients à risque intermédiaire ou à haut risque (délai d’intervention selon sévérité initiale)

Background
Glycoprotein IIb/IIIa inhibitors (GPI) may improve the results of primary PCI in acute STEMI
Pretreatment with a 300mg loading dose of clopidogrel improved the outcome of patients undergoing PCI in the setting of the CLARITY trial
A higher, 600mg loading dose of clopidogrel further enhances and accelerates platelet inhibition

Conclusion
In patients with acute STEMI undergoing
primary PCI after pre-treatment with a 600mg
loading dose of clopidogrel, the additional use
of abciximab is not associated with further
reduction in infarct size

PLATO study design
6–12 months treatment
PCI = percutaneous coronary intervention; CV = cardiovascular; PI = principal investigator
NSTEMI ACS (moderate-to-high risk) STEMI (if primary PCI) (N=18,624)Clopidogrel-treated or -naive; randomized <24 hours of index event
At randomization, 13,408 (72%) of patients were specified by the Investigator: intent for invasive strategy
Primary endpoint: CV death + MI + Stroke Primary safety endpoint: Total major bleeding
Clopidogrel (n=6,676)If pre-treated, no additional loading dose;if naive, standard 300 mg loading dose,
then 75 mg qd maintenance;(additional 300 mg allowed pre-PCI)
Ticagrelor (n=6,732)180 mg loading dose, then
90 mg bid maintenance;(additional 90 mg pre-PCI)

Conclusion 1
Anti platelets agents.
Rapid and profound anti platelet inhibition is mandatory Oral +/- Parenteral
New Drugs
Anti thrombin agents
We need to look for drugs with maximum efficacy and …..safety.
![Page 64: Recent advances in anti platelet therapy in ACS](https://reader031.vdocuments.us/reader031/viewer/2022013004/568144d6550346895db1a19d/html5/thumbnails/64.jpg)
64
Is It « Aspirin Prasugrel, Bivalirudin », the future very best association in PPCI??
What about Cangrelor associated to Enox or Biva.
More Trials need to be done to give the real place of theses new drugs in the ACS
Conclusion 2
