Current Primary Outcome Measures  ICMJE
 (submitted: October 21, 2010)
  • 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. [ Time Frame: 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. [ Time Frame: During 6 h at visit 3 ]
Original Primary Outcome Measures  ICMJE Same as current
Change History
Current Secondary Outcome Measures  ICMJE
 (submitted: October 21, 2010)
  • 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. [ Time Frame: 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. [ Time Frame: During 6h at visit 2 ]
