Coronary media shows a very reduced capacity to add after birth new rows of smooth muscle cells to the preexisting ones, in contrast to the media of other organ arteries. This medial deficiency is compensated by a rapid and diffuse intimal thickening which acts as an atherogenic factor. In addition the prevalence of longitudinally arranged smooth muscle cells in many segments of the coronary bed suggests that these segments react in a different manner to nervous stimuli, catecholamines and drugs.
与其他器官动脉的中膜相比，冠状动脉中膜在出生后向已有的平滑肌细胞添加新的平滑肌细胞行的能力非常有限。这种中膜缺陷通过快速且弥漫性的内膜增厚得到代偿，而内膜增厚是一种致动脉粥样硬化因素。此外，冠状动脉床许多节段中纵向排列的平滑肌细胞的普遍存在表明，这些节段对神经刺激、儿茶酚胺和药物的反应方式不同。
