Abstract
A study was conducted on the effects of vitamin C and cigarette smoking on endothelium-dependent vasodilation. Measurements were made of lumen diameter and flow velocity of the brachial arteries at rest, during reactive hyperemia and after sublingual nitroglycerin. The results indicate that endothelium-dependent vasodilation in the brachial arteries is impaired in smokers, which can be improved by vitamin C administration.
