SMART PAD Trial Summary

This trial will address two barriers to exercise therapy in people with PAD to improve walking distance, reduce disability, and increase exercise tolerance. Participants will do either supervised treadmill exercise or home-based walking exercise with or without nitrate-rich beetroot juice.

Who is the study for?
This trial is for individuals over 50 with Peripheral Arterial Disease (PAD), evidenced by specific tests. They must not have severe limb ischemia, amputations, or be wheelchair-bound. Participants should not already be highly active or have major health issues like end-stage kidney disease, recent surgeries, certain cancers, unstable angina, or dementia.Check my eligibility
What is being tested?
The study compares four approaches to improve walking in PAD: supervised treadmill exercise with beetroot juice; the same exercise with a placebo; home-based walking with beetroot juice; and home-based walking with a placebo. The goal is to find out which combination is most effective for reducing PAD-related disability.See study design
What are the potential side effects?
Potential side effects may include reactions to beetroot juice such as stomach upset or allergic reactions. Exercise might cause muscle soreness or exacerbate symptoms of PAD temporarily.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What is the current enrollment of this trial?

"This clinical trial requires 210 qualified participants. These patients can be sourced from the University of Chicago in Minneapolis, Minnesota and the University of Virginia in Charlottesville, Virginia."

Answered by AI

What detrimental effects can arise from executing a treadmill routine with nitrate rich beetroot juice?

"The safety of supervised treadmill exercise combined with nitrate rich beetroot juice was rated a 3 due to the multiple rounds of data that supports its efficacy and protective benefits."

Answered by AI

Are participants still being sought to join this medical experiment?

"The most recent information from clinicaltrials.gov indicates that the trial is actively seeking patients, having first been published on September 8th 2023 and being updated as recently as September 7th of that same year."
