Am Heart J 2011;161:650-656 NEJM 2013;369:999-1010 Clinical questions and rationale of the study To answer the question: IN NSTEMI patients, does having good inhibition of P2Y12 mediated platelet activation and aggregation prior to the start of PCI reduce the incidence of ischemic events compared to administration of a fast acting inhibitor (prasugrel) on the table?” Potential benefits of pretreatment: Prevention of ischemic events in NSTEMI patients while waiting for the PCI, during and after PCI. Potential risks of pretreatment: Bleeding risks need to be considered when starting platelet inhibition in NSTEMI patients before the coronary anatomy is known (eg, the patient will not be a candidate for PCI- medical management or CABG).

NEJM 2013; epub Sept 1 Overall Conclusions In NSTEMI patients managed invasively within 48 hours of randomization, pre-treatment with prasugrel does not reduce major ischemic events up to 30 days and increases major bleeding complications. The efficacy and safety results are consistent among patients undergoing PCI No subgroup appears to have a favorable risk/benefit ratio with pre-treatment. Considerations Overall Conclusions (L. Oltrona) in intermediate risk NSTEMI patients early invasively managed (median 4.3 hrs post randomisation) pre-treatment with 30 mg of prasugrel (+ 30 mg at the time of PCI) does not reduce major ischemic events up to 30 days but increases major bleeding complications. ( The efficacy and safety results are consistent among patients undergoing PCI. No subgroup appears to have a favorable risk/benefit ratio with pre-treatment) Drug failure or strategy failure ?
