The Effects of Omega-3 Fatty Acids Supplementation on Endothelial Function and Inflammation - Full Text View

Purpose

The hypothesis being tested is that in patients with stable claudication and documented PAD, omega-3 supplementation for 1 month will lead to improvement in endothelial function as measured by flow-mediated, brachial artery vasodilation (FMD), as well as improvement in the vascular inflammatory profile as measured by a panel of established circulating inflammatory biomarkers.
