Predicting Plaque Growth Using Blood Flow Stress Markers: A Proof-of-Concept Study

Sponsor: Queen Mary University of London

Summary

Coronary artery disease occurs when fatty deposits (plaques) build up inside the arteries that supply blood to the heart. Some plaques remain stable, while others continue to grow or become more likely to rupture, which can lead to a heart attack. Identifying plaques that are at higher risk of progression could help doctors provide earlier and more personalized treatment. The purpose of this study is to determine whether combining information about blood flow within the coronary arteries with information about a person's biological response to blood flow can improve prediction of plaque growth. Participants undergoing treatment for coronary artery disease will have a specialized heart scan to assess blood flow patterns around plaques in their coronary arteries. Researchers will also collect blood samples to study cells that line blood vessels and investigate how these cells respond to blood flow forces. The study will follow participants over time to determine whether plaques are more likely to progress in individuals who show a stronger biological response to abnormal blood flow. The findings may help researchers develop new ways to identify patients at higher risk of future heart problems and support the development of more personalized approaches to prevention and treatment of coronary artery disease.
