PRIMARY outcome

Timeframe: 2 hours after the loading dose

Population: Pharmacodynamic (PD) Analysis Set (N=93; 46 on ticagrelor, 47 on clopidogrel) - included all participants with PD data and without a major protocol deviation thought to significantly affect the PD of ticagrelor or clopidogrel. Participants in the PD Analysis Set with low (\<150) baseline PRU values were excluded from the analyses.

Participants with low (\<150) baseline PRU values were excluded.
