A relationship was examined between the development of myocardial ischemia in patients with coronary heart disease before coronary ventriculography and the status of coronary vessels, coronary reserve, myocardial contractility, and the autonomic nervous system. Before coronary ventriculography, myocardial ischemia was found to occur in the patients when there was a marked activation in the sympathetic portion of the autonomic nervous system and a clear-cut decrease in coronary reserve. The occurrence of myocardial ischemia in the patients before coronary ventriculography contributed to decreased left ventricular myocardial contractility and increased the cardiodepressive effects of a contrast agent.
研究了冠心病患者在冠状动脉造影前心肌缺血的发生与冠状动脉血管状况、冠状动脉储备、心肌收缩力和自主神经系统之间的关系。在冠状动脉造影前，发现当自主神经系统的交感部分明显激活且冠状动脉储备明显降低时，患者会发生心肌缺血。患者在冠状动脉造影前发生心肌缺血会导致左心室心肌收缩力下降，并增强造影剂的心脏抑制作用。
