作者确信,在心肌缺血所致各种病理生理学表现中,冠状动脉血管运动起着重要作用。但作者并不认为冠状动脉痉挛是解释缺血性心脏病各种临床表现的唯一机制。图1是冠状动脉固定性狭窄和动力性狭窄促进心肌缺血发生的理论模式。图中考虑的四个因素是:(1)生理学特征(如冠脉血流量及心肌
The authors are convinced that coronary artery movement plays an important role in various pathophysiological manifestations caused by myocardial ischemia. However, the author does not believe that coronary artery spasm is the only explanation for the various clinical manifestations of ischemic heart disease. Figure 1 is a fixed pattern of coronary artery stenosis and dynamic stenosis promote myocardial ischemia in the theoretical model. The four factors considered in the figure are: (1) Physiological characteristics (such as coronary blood flow and myocardium
