The elderly represent a growing segment of the coronary population treated by dual antiplatelet therapy for percutaneous coronary intervention (PCI). These patients bear a higher risk of both ischemic events and bleeding complications than younger patients, with a subsequently higher rate of mortality.Recentprogress in antithrombotic treatment demonstrated the efficacy of adding a P2Y12 receptor antagonist to low-dose aspirin. Whether this benefit is also present in the elderly remains a debated issue due to the lack of specific data in this sub-population. The present study was realized to provide specific data on platelet response to clopidogrel, standard dose (75 mg) or prasugrel 5 mg in elderly patients (≥75 years old) whereas the superiority in PR response of the latter should allows the Prasugrel therapy in elderly patients with the better clinical efficacy and therapeutical safety already showed compared with Clopidogrel.

Further study details as provided by University of Roma La Sapienza:

Primary Outcome Measures:
  • superiority of prasugrel low dose [ Time Frame: 30 days ]
    The primary aim will be to investigate the antiplatelet effect of half dose of prasugrel (5 mg) versus standard dose of clopidogrel in patients with acute coronary syndrome and coronary diseases, treated with percutaneous coronary intervention and stent implantation.

Secondary Outcome Measures:
  • Bleeding [ Time Frame: 12 months ]
    Bleeding (major, minor, or minimal according to the TIMI study criteria)

  • major adverse cardiac events [ Time Frame: 12 months ]
    major adverse cardiac events (cardiovascular death, myocardial infarction, and stroke) will be evaluated during the all period of treatment.

Estimated Enrollment: 68
Study Start Date: March 2013
Estimated Study Completion Date: July 2013
Estimated Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
