冠状动脉粥样硬化性心脏病(简称冠心病)的基本问题是粥样硬化病变使冠状动脉管腔狭窄导致的心肌缺血。然而心肌缺血往往与冠状动脉病变程度不呈平行关系,冠状动脉管腔较畅通者也可发生明显心肌缺血,提示心肌缺血可由于血管痉挛引起,血管痉挛最常发生在冠状动脉有粥样斑块的部位,它对冠心病临床表现、病程和预后的影响及其治疗的特殊性。目前已引起广泛的重视。
Coronary atherosclerotic heart disease (referred to as coronary heart disease) is the basic problem of atherosclerosis coronary artery stenosis caused by myocardial ischemia. However, myocardial ischemia is often not parallel with the severity of coronary artery disease, coronary artery lumen relatively unobstructed can also be significant myocardial ischemia, suggesting that myocardial ischemia can be caused by vasospasm, vasospasm most often occurs in the coronary artery porridge The plaque site, its clinical manifestations of coronary heart disease, duration and prognosis and the special treatment. At present, it has aroused widespread attention.
