Coronary Artery Disease Clinical Trial
Official title:
Ticagrelor in Comparison to Prasugrel for Inhibition of Platelet Reactivity, in Patients With Acute Coronary Syndrome (ACS) Presenting Resistance to the Usual Clopidogrel Dose After PCI
This is a single-center, randomized, single-blind, investigator-initiated pharmacological study with a crossover design. Patients with acute coronary syndrome (ST-elevation myocardial infarction, non-ST elevation myocardial infarction, unstable angina) and presenting high on-clopidogrel platelet reactivity as assessed with the VerifyNow assay (platelet reactivity units PRU≥235) 24 hours post percutaneous coronary intervention (PCI), will be randomized after informed consent in a 1:1 ratio to either prasugrel 10mg/d or ticagrelor 90mg twice a day for 15 days. Platelet reactivity assessment will be performed at Day 15±2 days and then a crossover directly to the alternate treatment group for an additional 15 days period, without an intervening washout period will be carried out. Patients will return at Day 30±2 days for platelet reactivity assessment.
