Ticagrelor De-escalation Strategy in AMI Patients

Summary

DAPT de-escalation strategies to reduce bleeding include de-escalation of DAPT intensity (downgrading from potent P2Y12 inhibitor at conventional doses to either clopidogrel or reduced-dose prasugrel) or abbreviation of DAPT duration. The EASTYLE trial will evaluate a hybrid DAPT de-escalation strategy (reduced-dose ticagrelor, followed by aspirin early discontinuation) in AMI patients, compared with a conventional DAPT strategy.
