心梗膨出是急性梗塞带的局部扩张和变薄。这种心腔形态改变的机理可能有如下几种:梗塞带变薄可由下列因素引起:1),细胞破裂,2)细胞间隙减少,3)心肌细胞伸长,4)心肌细胞束的滑动,使横跨心室壁的心肌细胞分布减少。为了确定这种心肌壁变 Myocardial infarction is a local expansion and thinning of the acute infarct zone. This mechanism of cardiac morphological changes may be the following: thinning of the infarct zone can be caused by the following factors: 1), cell rupture, 2) reduction of intercellular space, 3) myocardial cell elongation, 4) myocardial cell bundle slip, Reduce the distribution of myocardial cells across the ventricular wall. In order to determine this myocardial wall change
