The possibility is suggested that cardiac aneurysms are formed when an infarcted region of the ventricular wall becomes elastically unstable and "blows out". The consequence of such a blowout could be a large saccular aneurysm or even cardiac rupture. We use a nonlinear stress-strain relation capable of describing both the passive and active myocardial wall to examine this possibility in terms of large-deformation membrane theory. Ventricular infarcts made of a material having physical properties like rubber would be expected to blow out, but those made of passive myocardium would not.
有一种可能性被提出，即当心室壁的梗死区域变得弹性不稳定并“膨出”时，心脏动脉瘤就会形成。这种膨出的后果可能是一个大的囊状动脉瘤，甚至是心脏破裂。我们使用一种能够描述被动和主动心肌壁的非线性应力-应变关系，根据大变形膜理论来研究这种可能性。由具有类似橡胶物理特性的材料制成的心室梗死区域预计会膨出，但由被动心肌制成的则不会。
