Testing Responsiveness to Platelet Inhibition on Chronic Antiplatelet Treatment For Acute Coronary Syndromes Trial

Summary

This study investigates whether a platelet function testing guided approach with a short-term (1 week) prasugrel treatment and a switch over to clopidogrel treatment in adequate responders to clopidogrel is non-inferior regarding the combined incidence of bleeding and thrombotic complications to a 12 month standard treatment with prasugrel in acute coronary syndrome (ACS) patients treated with percutaneous coronary intervention (PCI).
