This study is a 3-month, prospective, randomized controlled clinical trial designed to address the efficacy of the DASH dietary program combined with a home-based exercise program, quantified by a step activity monitor, to improve exercise and vascular outcome measures in patients with PAD.
This study seeks to (1) compare the changes in 6-minute walk distance (6MWD) and physical function quality of life in patients with peripheral artery disease (PAD) following a combined intervention of the dietary approaches to stop hypertension (DASH) dietary program plus a home-based exercise program, and following a home-based exercise program alone; and (2) compare the changes in microvascular function and inflammation in patients following the combined DASH diet and home-based exercise program, and the home-based exercise program alone. The investigators hypothesize that the combined DASH…
Inclusion Criteria: 1. History of claudication, 2. Presence of PAD, defined by meeting at least one of the following criteria (ABI at rest \< 0.90, or \> 20% decrease in ABI following a heel-rise exercise test in patients with a normal ABI at rest (\> 0.90), or history of peripheral revascularization. Exclusion Criteria: 1. absence of PAD, defined by meeting all of the following 3 criteria (ABI at rest \> 0.90), \< 20% decrease in ABI following a heel-rise exercise test, and no history of peripheral revascularization, 2. non-compressible vessels (ABI \> 1.40), 3. rest pain due to PAD (Fonta…
The DASH dietary program consists of a diet emphasizing foods rich in fruits, vegetables, whole grains, and low-fat dairy, in which patients record daily servings of fruits and vegetables. The home-based exercise program consists of intermittent walking to moderate claudication pain 3 times per week for 3 months in a home-based setting.
The home-based exercise program consists of intermittent walking to moderate claudication pain 3 times per week for 3 months in a home-based setting.
