Outcome Measures

Primary Outcomes (2)

  • Assess the effect of Ticagrelor compared to placebo on the adenosine induced coronary blood flow velocity response by estimating the change in area under the adenosine dose response curve before and after study drug.

    During 6 h at visit 2

  • Assess the effect of Ticagrelor compared to placebo on the adenosine induced coronary blood flow velocity response by estimating the change in area under the adenosine dose response curve before and after study drug.

    During 6 h at visit 3

Secondary Outcomes (3)

  • Effect of Ticagrelor compared to placebo on the adenosine induced coronary blood flow velocity by estimating the change in area under the adenosine dose response curve before and after infusion of theophylline.

    During 6 h at visit 2

  • Difference in basal blood flow (in the absence of adenosine) between Ticagrelor and placebo conditions before and after infusion of theophylline.

    During 6h at visit 2

  • Difference in basal blood flow (in the absence of adenosine) between Ticagrelor and placebo conditions before and after infusion of theophylline.

    During 6 h at visit 3
