Sulfasalazine and Endothelial Function
Study Details
Study Description
Brief Summary
Experimental studies suggest that systemic inflammation leads to endothelial dysfunction and atherosclerosis. This study will examine the effects of the anti-inflammatory drug sulfasalazine on endothelial function in patients with coronary artery disease. Subjects will be treated with sulfasalazine or to placebo for six weeks. After a two-week rest period, subjects will cross over to the alternative treatment. Endothelium-dependent flow-mediated dilation of the brachial artery will be studied before and after each drug. We hypothesize that anti-inflammatory therapy will reverse endothelial dysfunction in patients with coronary artery disease.
