ABSTRACT
BACKGROUND:
Elderly patients display higher on clopidogrel platelet reactivity as compared with younger patients. Treatment with prasugrel 5mg has been shown to provide more predictable and homogenous antiplatelet effect, as compared with clopidogrel, suggesting the possibility of reducing ischemic events after an acute coronary syndrome (ACS) without increasing bleeding. STUDYDESIGN:
The Elderly-ACS 2 study is a multicenter, randomized, parallel-group, open-label trial designed to demonstrate the superiority of a strategy of dual antiplatelet treatment using a reduced 5-mg daily dose of prasugrel over a standard strategy with a daily clopidogrel dose of 75mg in patients older than 74years with ACS (either ST- or non-ST-elevation myocardial infarction) undergoing early percutaneous revascularization. The primary end point is the composite of all-cause mortality, myocardial reinfarction, disabling stroke, and rehospitalization for cardiovascular causes or bleeding within 1 year. Taking advantage of the planned size of 2,000 patients, the secondary objective is to assess the prognostic impact of selected prerandomization variables (age, sex, diabetic status, serum creatinine level, electrocardiogram changes, abnormal troponin levels, basal and residual SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery [SYNTAX] score).CONCLUSION:
The Elderly-ACS 2 study is a multicenter, randomized trial comparing a strategy of dual antiplatelet therapy with a reduced dose of prasugrel with a standard dose of clopidogrel in elderly patients with ACS undergoing percutaneous revascularization (the Elderly ACS 2 trial NCT01777503).
