| Research Abstract |
To clarify the mechanism which is responsible for the plaquerupture, we investigated the expression of sodium/calcium ion exchanger and matrix metalloproteinase and the stress/strain distribution in the human carotid arterial wall. Activated macrophages in fibrous cap expressed sodium/calcium ion exchanger-1 and matrix metalloproteinases-2 and 9 in atherosclerotic plaques. Therefore, these cells may contribute to the thinning and disruption of fibrous cap in the plaque. In addition, the concentration of the maximal principal stress is likely to trigger the plaque rupture.
