SMART Exercise

for Peripheral Arterial Disease

Supervised exercise therapy (SET), consisting of treadmill exercise conducted three times weekly at a center while supervised by healthcare personnel, is first line therapy for people disabled by lower extremity peripheral artery disease (PAD). However, travelling three times/week to a center for SET is burdensome. Compared to SET, home-based exercise is more accessible and less burdensome. Yet, evidence-based guidelines recommend SET over home-based exercise for PAD. Walking exercise is first line therapy to improve walking distance for PAD, but it does not eliminate ischemic leg symptoms in most people with PAD. The investigators' work and that of others showed that nitrate-rich beetroot juice, which increases plasma nitrite, limb perfusion, and skeletal muscle function, significantly improved exercise tolerance and reduced non-response to exercise in people with and without PAD. The investigators will use a 2 x 2 factorial design to address two major barriers to achieving benefits from exercise therapy for PAD: First, guideline recommendations for supervised exercise therapy (SET) as first line therapy for PAD. Second, the inability of exercise therapy to eliminate PAD-related disability in most people with PAD. Participants will be randomized to one of four groups for 12 weeks: Supervised treadmill exercise + nitrate rich beetroot juice; supervised treadmill exercise + placebo, home-based walking exercise + nitrate rich beetroot juice, home-based walking exercise + placebo.

Exercise and Beetroot Juice

for Peripheral Arterial Disease

Lower extremity revascularization combined with supervised exercise significantly improves walking performance compared to revascularization alone in people who have PAD without limb threatening ischemia. However, supervised exercise is inaccessible or burdensome for most PAD patients. Investigators hypothesize that home-based exercise combined with lower extremity revascularization will significantly improve walking performance compared to revascularization alone in patients with PAD undergoing revascularization for disabling PAD. Investigators further hypothesize that inorganic nitrate, a major source of nitric oxide (NO) abundant in beetroot juice, will improve walking performance after lower extremity revascularization, compared to placebo. In preclinical models, NO inhibits inflammation, neointimal hyperplasia, thrombosis, and vascular smooth muscle cell migration at sites of revascularization. NO increases angiogenesis and perfusion, repairs skeletal muscle damaged by ischemia, and stimulates mitochondrial activity. In a randomized clinical trial with a 2 x 2 factorial design, the trial will test the following two primary hypotheses in 386 patients randomized within three months of a successful lower extremity revascularization for disabling PAD: First, that home-based exercise combined with lower extremity revascularization will improve six-minute walk distance more than revascularization alone at 6-month follow-up (Primary Aim #1). Second, that nitrate-rich beetroot juice combined with lower extremity revascularization will improve six-minute walk, compared to placebo combined with revascularization at 6-month follow-up (Primary Aim #2).

Fisetin

for PAD

The investigators propose a pilot randomized trial to gather preliminary data to test the hypothesis that Fisetin will reduce abundance of senescent cells in blood, skeletal muscle, and both subcutaneous and inter muscular adipose tissue and improve 6-minute walk distance in 34 people with peripheral artery disease (PAD). the investigators will determine whether greater declines in abundance of cells with senescent markers are associated with greater improvement in 6-minute walk distance in people with peripheral artery disease. In exploratory analyses, the investigators will assess whether Fisetin reduces interleukin-6 (IL-6) and novel senescent markers in adipose tissue, muscle, and/or blood.
