Atherosclerosis is associated with a number of structural and functional changes in the arterial wall. Endothelial dysfunction, oxidised-LDL accumulation, increased concentrations of macrophages, neutrophils and T-cells as well as smooth muscle cell migration are some of the most relevant changes that take place during atherogenesis and coronary artery disease progression. It has been shown that the presence of a space-occupying plaque is commonly associated with the expansion of the arterial wall (vessel remodelling).1 The mechanisms responsible for this phenomenon are speculative.
1. Positive and negative vessel remodelling
The majority of coronary artery atheromatous plaques are eccentric and tend to grow towards the adventitia before encroaching upon the lumen of the artery. This was shown initially by Glagov et al.1 in a pioneering study, which demonstrated thatleft main coronary
