Near-Infrared Diffuse Correlation Spectroscopy to Better Define the Pathophysiology of Peripheral Artery Disease
The University of Texas at Arlington
Summary
The goal of this study is to better understand how blood flows and how oxygen is utilized in the lower limbs of people who suffer from peripheral artery disease. This study will also assess how these factors affect treatment outcomes. Specific aims include: Aim 1: Utilize BB-NIR-DCS to differentiate PAD patients experiencing primary oxygen delivery limitations from those suffering from mitochondrial dysfunction. Aim 2: Test the efficacy of BB-NIR-DCS at predicting individual responses to vascular intervention.
Description
Subjects that do not have peripheral artery disease will complete the study procedures up to two times (baseline and follow-up at 1-2 months). Subjects diagnosed with peripheral artery disease may be asked to complete the study procedures up to 4 separate times (baseline, follow-up at 1-2 weeks, 1-2 months, and 4-6 months). The investigators will work with them to schedule each visit. All participants will provide informed consent prior to participating in the study. The screening procedures will include collecting information about health history, age, sex, race/ethnicity, height, weight, a…
