  Purpose

To test the vasoactive and anti-inflammatory effects of prasugrel in patients with acute coronary syndrome endothelial function -as a surrogate parameter of NO bioavailability- and different markers of inflammation, oxidative stress and platelet activation will be assessed in patients with unstable angina.

Platelet Inhibition
Drug: Prasugrel or Clopidogrel
Phase 3

Study Type: Interventional

Primary Outcome Measures:
  • Assessment of endothelial function (FMD) via high-resolution ultrasound (Sonoline G50, 12 MHz linear array transducer, Siemens, Germany) by experienced sonographer [ Time Frame: baseline and after 3 months ] [ Designated as safety issue: No ]
    The primary endpoint is the change of endothelial function given in % from baseline to 3 months after therapy with prasugrel versus clopidogrel.
