目的评价左冠状动脉回旋支急性闭塞超急期心电图特征及演变规律。
Objective To evaluate the character and variation of ECG during the acute phase of obliteration in circumflex branch of left coronary artery.
结论MSCT能用于检测急性心肌梗死，同时能发现造成急性心肌梗死的冠状动脉狭窄或闭塞。
Conclusions MSCT can be used to assess acute myocardial infarctions and infarct-related coronary artery stenosis or occlusion.
血栓形成在急性冠状动脉血管闭塞中起关键作用。
Thrombosis plays an important role in acute coronary obstruction.
无急性闭塞而需急诊行冠状动脉旁路移植术及急性心肌梗死发生。
No abrupt coronary closure, emergency bypass surgery and acute myocardial infarction occurred.
当心肌梗塞或心绞痛时，在急性或亚急性闭塞动脉中，PCI可以恢复冠状动脉血流量（或冠脉灌注）。
The procedure restores coronary arterial flow (or coronary perfusion) in an acutely or sub-acutely occluded artery during acute myocardial infarction or unstable angina.
结论肌钙蛋白升高的非ST段抬高型急性冠状动脉综合征患者冠状动脉造影特点为血栓发生率高、狭窄较重、血管闭塞率高、血流较慢、心肌组织灌注不良者多。
Conclusions The angiographic features in patients with NSTE-ACS are of higher incidence of thrombus, tighter percent stenoses, higher rate of vesse1 occlusion and closed microvasculature.
