Testing a new way to predict critical limb ischemia
Part of Heart & circulation clinical trials.
This trial uses a Doppler ultrasound to measure blood flow speed in your leg arteries to see if it can better predict a severe form of peripheral artery disease called critical limb ischemia. You may qualify if you have known artery disease in your leg and are already scheduled for a toe blood pressure test.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You are being seen at a vascular medicine clinic for a leg artery ultrasound.
- You will also have a blood pressure measurement taken at your toe.
- You have known artery disease in your leg, shown by a low ankle blood pressure (≤0.90) or low toe blood pressure (≤0.70).
- You are not scheduled for leg surgery for artery disease at this time.
- You have not had a foot amputation that would prevent toe blood pressure readings.

This study measures how blood flows through your foot using ultrasound to see if it can predict serious problems with your leg or heart in people with severe circulation problems. The goal is to find a simple test that helps doctors decide the best treatment for you.
This trial tests an experimental drug for people with critical limb ischemia, a serious condition where not enough blood reaches the legs. It aims to see if the drug can help with pain or healing of leg ulcers without the need for surgery.
This study follows adults with very poor blood flow to the foot or leg (with wounds or severe pain) who are having a revascularization procedure to improve circulation. It may help doctors understand outcomes after treatment and improve care for people with critical limb ischemia.
This trial is testing a new way to check for blocked arteries in people with diabetes who have foot ulcers. The goal is to see if this test can help doctors diagnose blood flow problems more accurately.
This trial tests a new camera that uses light to check blood flow in your legs. It compares the camera's results to standard tests like ABI and Doppler ultrasound to see if it works as well.
This study registers people with severely blocked leg arteries below the knee, causing pain or wounds that are limited to the toes or forefoot. Doctors will use a special tool to measure toe pressure and guide treatment to open the blocked arteries and save the limb.
