Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • Inhibition of the P2Y12 Receptor at 2 Hours After Loading Doses of Ticagrelor and Clopidogrel as Measured by P2Y12 Reaction Units (PRU) From VerifyNow™ [ Time Frame: 2 hours after the loading dose ]
    Participants with low (<150) baseline PRU values were excluded.

Secondary Outcome Measures:
  • Inhibition of the P2Y12 Receptor at 0.5 Hours, End of PCI, and 8 Hours After Loading Doses of Ticagrelor and Clopidogrel as Measured by PRU From VerifyNow™ [ Time Frame: 0.5 hours, end of PCI, and 8 hours after the loading dose ]
    Participants with low (<150) baseline PRU values were excluded.

Enrollment: 343
Study Start Date: July 2012
Study Completion Date: June 2014
Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
