1. Objective: To evaluate the value of coronary artery calcification(CAC) detected with digital fluoroscopy in diagnosis of coronary artery disease (CAD). 目的：评价数字荧光透视检出冠状动脉钙化（CAC）对诊断冠心病的价值。

3. Left circumflex originated from the right coronary artery, single right coronary, and two separate coronaries originated from the right coronary sinus were the main variations. 回旋支发自右冠状动脉、单支右冠状动脉、右冠状窦内两支冠状动脉比较多见。
4. Coronary artery vasospasm can cause a transient, abrupt, marked decrease in the diameter of an epicardial coronary artery. 冠状动脉血管痉挛能造成一个暂时的，突然的，显著的心外冠状动脉内径的减少。
5. The coronary arteriogram disclosed patent coronary artery with slight intraluminal haziness in the proximal left anterior descending artery. 在病况稳定后进行冠状动脉摄影，结果显示冠状动脉是畅通的。只有在左前降枝近端有轻微管内血栓。
