English-Hanzi/When part of the inner layer of the coronary artery becomes hard

When part of the inner layer of the coronary artery becomes hard, coronary heart disease occurs. When suffering from coronary hardening, the inner layer of the coronary artery becomes harder and harder, and builds up calcium, fatty lipids and abnormal inflammatory cells to form a plaque. 当冠状动脉内层的一部分变硬时，就会发生冠心病。 当患有冠状动脉硬化时，冠状动脉的内层变得越来越硬，并积聚钙，多脂脂质和异常的炎症细胞以形成斑块。
