NCT01641510

Brief Summary

The investigators hypothesize that reduced loading dose of prasugrel followed by reduced maintenance dose of prasugrel in acute coronary syndrome patients with CYP2C19 polymorphism undergoing percutaneous coronary intervention might exhibit lower platelet reactivity 24 hours and 30 days later which is associated with major adverse cardiovascular events.
