冠状动脉病(冠脉病)在美国是威胁健康的首位疾病,患病人数达2亿。冠脉病有三种类型的表现:稳定型心绞痛(SAP)、不稳定型心绞痛(UAP)和急性心肌梗死(AMI)。发病机理和治疗原则 SAP:发作前总是有一定的应激,使心肌需要过多的O_2。冠脉狭窄的成分在早期是脂质沉积。在美国发生年龄较早,从士兵尸检发现18~20岁即可存在,但形成狭窄要经过多年。血管痉挛可造成心绞痛,尤其在部分年轻女性冠脉正常,甚至在痉挛基础上发生心梗。动脉硬化斑块的核心是胆固醇等脂质,外面裹
Coronary artery disease (coronary artery disease) is the first health-threatening disease in the United States, affecting 200 million people. There are three types of coronary artery disease manifestations: stable angina (SAP), unstable angina (UAP) and acute myocardial infarction (AMI). Pathogenesis and treatment of SAP: always have a certain stress before the attack, so that the myocardium need too much O_2. The components of coronary stenosis are lipid deposits in the early stages. Occurred in the United States earlier, from the soldiers found that 18 to 20 years old autopsy can exist, but the formation of narrow to go through for many years. Vasospasm can cause angina pectoris, especially in some young women with normal coronary arteries and myocardial infarction, even on the basis of spasticity. The core of atherosclerotic plaque is cholesterol and other lipid, wrapped outside
