Brief summary

The objective of this study is to compare reduced-dose prasugrel and standard dose clopidogrel in patients older than 74 years with ACS, including non-ST-elevation (NSTEACS) and ST-elevation (STEMI) patients, undergoing early PCI. The primary endpoint of the trial will be the one-year composite of (all-cause)death, myocardial infarction, stroke and re-hospitalization due to cardiovascular reasons or bleeding.

Inclusion criteria

\- Patients \>74 years of age hospitalized for an ACS, with or without STE, with an onset of symptoms during the previous 72 hours, and candidates to an early PCI. * STEMI patients may be randomized upon first diagnosis, provided they do not meet any

Exclusion criteria

. STEMI patients should not exceed 50 percent of the global population of the study * Eligible NSTEACS patients may be randomized after coronary angiography. To be eligible, NSTEACS patients must have at least one of the following characteristics: * elevated troponin levels; * diabetes mellitus; * prior MI; * at least one new ischemic episode while on standard treatment during the index hospitalization; * ACS due to stent thrombosis.
