Inflammation plays an important role in the development of atherosclerosis. The initial site of damage is the endothelium and secondarily the rest of the vascular wall is involved. Hypotheses concerning the development of these lesions have introduced the concept of oxidative stress, ("an imbalance between oxidants and antioxidants in favor of the oxidants, potentially leading to damage") as having a key role in the development of atherosclerosis. Consequently, much interest has been focused on attenuating oxidative stress in order to minimize this damage.
