Brief Summary:
The purpose of this study is to determine whether carnosine (a food ingredient found in chicken and red meat) supplementation (2 g) for 6 months in participants with non-claudication and claudication peripheral arterial disease (PAD) improves walking ability. Previous studies with heart failure patients have shown that carnosine supplementation increases walking capacity in these patients.
Detailed Description:
The objective of this double-blinded longitudinal study is to determine whether carnosine supplementation (2 g) for 6 months in participants with non-claudication and claudication peripheral arterial disease (PAD) improves walking ability. In this pilot study we will enroll 144 participants that will be divided into placebo (n=72) and carnosine groups (n=72). We will measure the distance covered on the 6-minute walk test (6-MWT) and the pain free walking capacity on the treadmill before and after the placebo or carnosine supplementation. We will measure ankle branchial index (ABI) and blood flow by magnetic resonance imaging (MRI) before and after the carnosine and placebo supplementation. In addition, we will measure carnosine by 1HMRS (Proton magnetic resonance spectroscopy), perform, global metabolomics and proteomics in the skeletal muscle, a comprehensive lipid and metabolic profile of blood, uptake of carnosine in red blood cells (RBCs), and measure carnosine aldehyde conjugates in the urine before and after 6 months of carnosine and placebo supplementation. Following completion of the study, we will follow the participants for another 3 months and examine the durability of carnosine supplementation.
