Abstract
Endothelial dysfunction and platelet activation are cornerstones in the pathogenesis of atherothrombosis, leading to vasoconstriction, thrombus formation, and inflammation. Smoking is a major cardiovascular risk factor. The mechanisms promoting atherothrombosis in smokers primarily include increased oxidative stress that enhances proatherogenic processes such as low density lipoprotein oxidation and inactivation of endothelium derived nitric oxide. Platelets contribute both to acute coronary syndromes and to the progression of atherothrombosis. Both active and passive cigarette smoking has consistently been shown to induce endothelial dysfunction. Therefore, smokers serve as an ideal model to study the beneficial vascular effects of antioxidant strategies such as dark chocolate.1Keywords
