STARTREC: Simplifying Technologies for peripheral ARTerial disease RECognition

Principal Investigator: Mr Matt Bown
Start Date: April 2014

Peripheral arterial disease (PAD) affects one in five people between the ages of 55 and 75 years. Despite advances in medical care and technology, PAD remains a worldwide problem. Current bedside diagnosis of PAD relies on the Ankle Brachial Pressure Index (ABPI), which is often used in combination with a walk test. However, current tests may underdiagnose patients who are elderly, who have diabetes, or who have chronic kidney failure. Furthermore, the ABPI is rarely used for PAD diagnosis by General Practitioners (GPs), as it is time consuming and problematic in patients with walking difficulties. There is a need for a more effective diagnosis of PAD, and technological advancements may play a key role in meeting this need.

Inspired by the ‘Medical Tricorder’ of the popular Star Trek series, the STRATREC study aims to identify novel technologies to help diagnose patients with PAD more accurately and reliably. Patients with PAD symptoms of all severities will be studied using novel technologies, and compared to the ABPI. At follow-up, patients’ disease progression or improvement will be assessed against these diagnostic tests. Technologies to be studied will include Near Infrared Spectroscopy (NIRS), Laser-based technology, Transcutaneous oximetry, Thermometry, Smart phone technology and Automated ABPI devices. We hope to identify technologies that are able to diagnose PAD or predict its outcome more reliably by the end of this study.
