Dual Antiplatelet Therapy Tailored on the Extent of Platelet Inhibition

Summary

The purpose of this study is to evaluate the efficacy (reduction of major ischemic events at 6 and 12 months of follow-up) of a tailored clopidogrel therapy in patients with UA/NSTEMI undergoing PCI with stent implantation and wiht a documented residual platelet reactivity assessed by a point of care system (VerifyNow P2Y12).
