Abstract

Vulnerable plaques are characterized by the presence of a large lipid pool, which is separated from the lumen by a thin fibrous cap, often infiltrated by macro phages [Schaar-04]. Rupture of this fibrous cap is generally regarded as one of the main underlying causes of cardiovascular events [Fa!k-95]. Rupture occurs when the stresses in the cap of the plaque exceed the strength of the cap [Lee-93]. The composition of the plaque plays a crucial role in the rupture process: it determines how blood pressure is translated into stresses in the wall, and composition also determines the strength of the tissue [Loree-94, Holzapfel-05].
