O xidative stress has long been associated with a wide range of cardiovascular risk factors and likely contributes to the progression of cardiovascular diseases in animal models and in humans. Numerous lines of evidence indicate that pathways of oxidative and nitrative stress can contribute to cardiovascular disease via multiple mechanisms, such as through formation of atherogenic lipoproteins,...
