Effects of Carnosine In Patients With Peripheral Arterial Disease Patients; Randomized Intervention Trial (CIPHER)
Shahid Baba
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.
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 fl…
