The mortality benefit seen with the newer more potent oral P2Y12 inhibitors prasugrel and ticagrelor over clopidogrel is dependent on the underlying risk: A class effect as suggested by a meta-regression analysis

In the ACS patients studied, we found a mortality benefit with the two newer oral P2Y12 inhibitors prasugrel and ticagrelor when compared with clopidogrel, which increases progressively as the underlying risk of death increases. This appears to be a class effect for these two newer agents.
