Objective To evaluate the characteristics of myocardial perfusion and therapeutic effect of acute myocardial infarction using first pass perfusion MR imaging.
目的：通过MR灌注成像评价急性梗死心肌组织血流灌注特点。
Objective:To evaluate the characteristics of myocardial perfusion using first pass perfusion MR imaging.
无再流现象是指冠状动脉闭塞，血流中断后重新恢复血流，却无心肌组织的有效灌注的现象。
No reflow phenomenon refers to non-effective perfusion in myocardium when the flow regains after flow blockage resulting from coronary artery occlusion.
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.
