冠状动脉粥样硬化性心脏病,简称冠心病。主要病变是冠状动脉内膜脂质沉着,局部结缔组织增生,纤维化或钙化,形成粥样硬化斑块,造成管壁增厚,管腔狭窄或阻塞。当体力活动或情绪激动时,心脏搏动次数增多,收缩力增强,心室张力增高,而此时由于冠状动脉狭窄供血量不能相应增多以满足心肌氧的需要,从而出现心肌缺血。病人表现为胸憋、胸痛、心绞痛等症状。 Coronary atherosclerotic heart disease, referred to as coronary heart disease. The main lesion is coronary intimal lipid deposition, local connective tissue hyperplasia, fibrosis or calcification, the formation of atherosclerotic plaque, resulting in thickening of the wall, stenosis or obstruction. When physical activity or emotional, cardiac beats increased, contractility increased, increased ventricular tension, but this time due to coronary artery stenosis can not be a corresponding increase in blood supply to meet the needs of myocardial oxygen, resulting in myocardial ischemia. Patients showed chest choke, chest pain, angina and other symptoms.
