Strathclyde Open Access research that creates ripples...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of research papers by University of Strathclyde researchers, including by Strathclyde physicists involved in observing gravitational waves and black hole mergers as part of the Laser Interferometer Gravitational-Wave Observatory (LIGO) - but also other internationally significant research from the Department of Physics. Discover why Strathclyde's physics research is making ripples...

Strathprints also exposes world leading research from the Faculties of Science, Engineering, Humanities & Social Sciences, and from the Strathclyde Business School.

Abstract

Fatty deposits formed on arterial walls lead to atherosclerosis but it is the interplay between these deposits and the vessel walls which governs the growth of plaque formation. Cells in the vessel walls trigger the body's defenses and through a series of mechanisms lead to the promotion of plaque growth. Crucially however the vast majority of acute coronary syndromes such as, myocardial infarction, and sudden ischaemic cardiac death is caused by atherosclerotic plaque rupture and not from a stenosis growing and blocking the blood flow. Although the stress caused by the blood flow does play a role in plaque rupture, it has been found that the degree of stenosis is a relatively minor factor in predicting which plaques are most prone to rupture. In fact, atherosclerotic plaques expand into the vessel wall during much of their existence and this can make their detection problematic.
