Purpose

The aim of the study is to show the implication of platelets in vasodilation using in vivo and in vitro analysis and to compare the effects of placebo, aspirin and Clopidogrel in this interaction platelets/vessels.

The effects of 7 days of each treatment will be compared in healthy subjects and patients with arteriopathy.
