| 摘 要： | 目的:探讨门控核素心肌灌注显像(G-MPI)对冠状动脉(冠脉)支架再狭窄的诊断价值.方法:65例冠脉支架术后3个月以上的患者行两日法负荷/静息99Tcm-甲氧基异丁基异腈(MIBI) G-MPI,所有患者的G-MPI与冠脉造影(CAG)均在同期的1个月内完成,其中先做CAG检查的患者未进行再次血运重建术.以CAG为标准,分析G-MPI诊断冠脉支架再狭窄的价值.结果:65例患者的88支冠脉共置入105枚支架,随访CAG发现38.5%(25/65)的患者出现支架再狭窄,发生再狭窄的支架数为29.5%(31/105);根据典型症状诊断支架再狭窄的敏感性、特异性和准确性分别为64.0%、22.5%、38.5%;心电图运动平板试验(ETT)诊断支架再狭窄的敏感性、特异性、准确性分别为41.2%、71.9%、61.2%;G-MPI诊断支架再狭窄的敏感性、特异性、准确性分别为92.9%、86.7%、88 6%,其准确性明显优于ETT(χ2=14.173,P<0.001)和症状(χ2=42.781,P<0.001).结论:G-MPI诊断冠脉支架术后再狭窄具有良好的价值.

| Abstract: | Objective:To investigate the value of gated myocardial perfusion imaging for evaluating stent restenosis following coronary stent implantation.Method:Sixty-five patients of CAD with stent implantation were envolled to assess restenosis and all patients underwent stress/rest 99Tcm-MIBI G-MPI within more than 3 months after PCI.Coronary angiography(CAG) was performed within 1 month before or after G-MPI test and target lesion revascularization were not performed if CAG was performed before G-MPI.The results o... |
