The process tending to focus on the sub endocardium.

趋向于集中于心内膜下的过程。

'It was a very simple case of endocarditis'.

“这是一个非的心内膜炎病例”。

Therefore the classic finding with angina is subendocardial ischemia, meaning less oxygen is reaching the region just under the endocardium.

因此心绞痛的典型发现就是心内膜下缺血，即到达心内膜下的氧减少。

In this case, eosinophils accumulate in the endocardial layer of the heart tissue, causing inflammation and endocardial fibrosis, making it stiffer and again less compliant.

在这类病例中，嗜酸性聚集在心脏组织的心内膜，导致炎症和心内膜纤维化，让其更加僵硬、顺应性更差。

Ischemia in the areas supplied by the partially occluded vessel illustrated here in the lateral wall of the left ventricle is primarily targeted on the sub endocardial aspect of the affected region.

左心室侧壁部分闭塞血管供应区的缺血主要是针对受影响区的心内膜下。

Whatever the case, the heart needs blood, and if we look at the heart wall, there's three layers—the outermost layer, the epicardium, then the myocardium in the middle, and the endocardium inside the heart.

无论什么情况下，心肌都需要供血，我们学习心壁时知道，心壁有3：最外的心外膜、中的心肌，以及心脏内的心内膜。
