57. 什么是冠心病？

答：冠心病是冠状动脉粥样硬化、狭窄、阻塞、或因此合并痉挛以及血栓形成，造成管腔阻塞引起冠状动脉供血不足、心肌缺血或梗塞的一种心脏病。虽少数年轻患者硬化不严重，但也可以发病。

有些老年人硬化性狭窄虽较严重，可并不一定都有临床表现，因此机理复杂，涉及问题多，有待进一步研究。

What Is Coronary Heart Disease?

Heart disease is caused by narrowing of the coronary arteries that feed the heart. Like any muscle, the heart needs a constant supply of oxygen and nutrients, which are carried to it by the blood in the coronary arteries. When the coronary arteries become narrowed or clogged by cholesterol and fat deposits--a process called atherosclerosis--and cannot supply enough blood to the heart, the result is coronary heart disease (CHD). If not enough oxygen-carrying blood reaches the heart, you may experience chest pain called angina. If the blood supply to a portion of the heart is completely cut off by total blockage of a coronary artery, the result is a heart attack. This is usually due to a sudden closure from a blood clot forming on top of a previous narrowing.
