Trial Outcomes & Findings for Different LD of Ticagrelor for Antiplatelet Effect in Patients With Non-ST-segment Elevation ACS Undergoing PCI (NCT NCT01962428)

NCT ID: NCT01962428

Last Updated: 2016-11-09

Results Overview

Vasodilator-stimulated phosphoprotein(VASP) phosphorylation, a measure of P2Y12 receptor reactivity, was determined by flow cytometry with the use of the Platelet VASP-FCM Kit (Stago, France)and recorded as the platelet reactivity index (PRI).
