Vulnerable Plaque: A Review of Current Concepts in Pathophysiology and Imaging

Advances in our understanding of the natural history and biology of atherosclerotic vascular disease led to the concept of a vulnerable plaque (VP), which is predisposed toward more rapid progression and acute coronary events. With newer technologies, we now have at our disposal high-quality imaging studies, both invasive and noninvasive, which promise in identifying plaque characteristics that make it more vulnerable. Upcoming trials aim to evaluate the utility of imaging VP in predicting clinical events. We discuss the role of VP imaging in managing atherosclerotic vascular disease.
