● Pre-treatment with aspirin and a P2Y12 antagonist has been a class I recommendation and common practice for the treatment of NSTE-ACS

● However, no trial has ever randomized patients presenting with NSTE-ACS, invasively managed, to pre-treatment with clopidogrel, prasugrel or ticagrelor vs. no pre-treatment.

Conclusions

● In NSTE-ACS patients managed invasively within 48 hours of admission, pre-treatment with prasugrel does not reduce major ischemic events through 30 days but increases major bleeding complications.

● The results are consistent among patients undergoing PCI supporting treatment with prasugrel once the coronary anatomy has been defined.

● No subgroup appears to have a favorable risk/benefit ratio of pre-treatment.

● Reappraisal of routine pre-treatment strategies in NSTE-ACS is needed.

Pre-specified clinical 2° endpoints

• Composite of death, MI, stent thrombosis, stroke or urgent revascularization at 30 days

• Definite stent thrombosis at 30 days

• Thrombotic bailout with GPIIb/IIIa inhibitors

Safety objectives

• Bleeding (excluding CABG related events)

– TIMI, STEEPLE, GUSTO, ISTH and BARC definitions

– Within first 48h and during 30 days of treatment

• Other safety events within 30 days of study treatment

Major adverse CV events up to 30 days

Definite stent thrombosis up to 10 days

Definite stent thrombosis up to 30 days

Clinical endpoints at 30 days

Conclusion

La administración prehospitalaria de Ticagrelor previo a la ICP en pacientes con SCACEST es segura pero no mejora la reperfusión. Sin embargo reduce el riesgo de trombosis de stent psot ICP
