Ischemia Clinical Trial
Official title:
A Randomized, Double-blind, Placebo-controlled, Parallel Group Study to Assess the Effect of Atorvastatin Treatment for 14 Days in Combination With an Acute Dose of Ticagrelor on Ischemia Reperfusion Induced Endothelial Dysfunction of the Forearm Vasculature in Healthy Male Subjects

To test the effect of atorvastatin or placebo in combination with ticagrelor on ACh-induced vasodilatation of the forearm resistance vasculature as assessed by forearm blood flow (FBF) measurement before and 10 min after a 20 min forearm ischemia. The area under the dose-effect curve (AUC) of different ACh doses will be calculated and compared between treatment groups (atorvastatin + ticagrelor vs. placebo + ticagrelor) and different time points (pre-ischemia vs. post-ischemia).
