Outcomes
Primary Outcome Measures
Assessment of endothelial function (FMD) via high-resolution ultrasound (Sonoline G50, 12 MHz linear array transducer, Siemens, Germany) by experienced sonographer
The primary endpoint is the change of endothelial function given in % from baseline to 3 months after therapy with prasugrel versus clopidogrel.

5. Study Description
Brief Summary
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.
Detailed Description
Trial Objectives 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.
Trial Design Single center, double blind, double-dummy, randomized, parallel trial.
Endpoints
Primary Endpoint Assessment of endothelial function (FMD) via high-resolution ultrasound (Sonoline G50, 12 MHz linear array transducer, Siemens, Germany) by experienced sonographer.
Secondary Endpoints
Non-invasive assessment of microvascular perfusion and oxygen saturation by laser Doppler perfusion imaging and tissue spectrometry (O2C, Lea Medizintechnik, Giessen, Germany)
Determination of leukocyte activity: plasma MPO levels (ELISA), plasma elastase levels (ELISA)
Assessment of platelet activity: plasma levels of sCD40 ligand (ELISA), RANTES (ELISA)
Measurement of different oxidative stress markers: hsCRP (ELISA), CD40 ligand (ELISA), carbonylated proteins (ELISA), urinary 8-iso-PGF2α (gas chromatography mass spectrometry)
Determination of platelet-leukocyte aggregates by fluorescent activated cell sorter (FACS)
Assessment of platelet function (PADA-test)
