摘　　要：目的:探讨用单光子发射型计算机断层(single photon emission computedtomography,SPECT)心肌灌注显像,评估心肌梗死(AMI)经冠脉介入治疗(PCI)后的心肌灌注疗效。方法:采用99mTc-tetrofosmin(P53)SPECT心肌灌注显像对54例行PCI治疗的AMI患者评估心肌灌注情况,并追踪记录6个月内心脏事件发生率。结果:SPECT显示无复流组22例,有复流组32例,两组心肌梗死患者近期预后差异有统计学意义(P<0.05)。无复流组不良事件发生率较有复流组有增加趋势;另外,急诊PCI组的预后明显好于择期PCI组,差异有统计学意义(P<0.05)。结论:SPECT心肌灌注显像可对AMI患者梗死相关血管(IRA)再通治疗疗效进行可靠的无创性评价。Objective： To investigate the role of single photon emission computed tomography （SPECT） myocardial perfusion imaging system in evaluation of the myocardial perfusion results in the AMI patients taking emergency PCI treatment. Methods： The 99mTc-tetrofosmin （p53） SPECT myocardial perfusion imaging system was used to evaluate the myocardial perfusion results in 54 AMI patients taking the PCI treatment and the incidence of cardiac events was recorded during the 6 months period. Results： The SPECT imaging showed that the difference in the immediate prognosis in the no-reflow group （22 cases） and reflow group （32 cases） was statistically significant （P〈0.05）. There was an increasing trend in the cardiac events occurrence in the NR group rather than the no-NR group. In addition, the prognosis in the emergency PCI group was much better than that in the date-selection PCI group and the difference was statistically significant （p〈0.05）. Conclusion： The SPECT myocardial perfusion imaging system can provide non-traumatic evaluation for the re-clearance treatment of the infarction-related artery in the AMI patients..
