冠脉痉挛可导致有或无重度粥样硬化性梗阻病人的心绞痛,尽管可能存在着其它机理,但按其病理生理研究,这种没有严重器质性狭窄的痉挛病人可归属于同一类型疾病,因其心肌缺血不是心肌氧需增加引起,而是血管舒缩功能障碍、冠脉血流减少所致。一般临床资料作者于1982年报道37例冠脉无重度狭窄因痉挛引起的心绞痛病人,男女之比为3:1,平均年龄52岁。休息时均有典型心绞痛发作,其中86％发生在夜间,46％有势力性心绞痛。86％抽
Coronary spasm can lead to angina pectoris in patients with or without severe atherosclerotic obstruction, although other mechanisms may exist, according to its pathophysiological study, this spasm-free patients with severe organic stenosis can belong to the same type of disease, Because of myocardial ischemia is not caused by increased myocardial oxygen demand, but vasomotor dysfunction, decreased coronary blood flow. General clinical data The author reported in 1982, 37 cases of severe coronary artery stenosis caused by cramps angina patients, male to female ratio of 3: 1, with an average age of 52 years. A typical episode of angina breaks at rest, with 86% occurring at night and 46% having exertional angina. 86% pumping
