Hunting for the Off-Target Properties of Ticagrelor on Endothelial Function in Humans (HI-TECH)

Summary

The purpose of this randomized, cross-over study, is to ascertain if ticagrelor, but not prasugrel or clopidogrel, is associated to an improved endothelial function as assessed with peripheral arterial tonometry and markers of endothelial function measurement in post-ACS patients.
