摘要 目的应用门控心肌灌注显像(GMPI)评估急性心肌梗死(AM I)患者介入治疗前后心肌血流灌注及心功能的变化。方法 30例经典型临床表现、特征心电图及实验室检查确诊为AM I的患者,首先完成静态门控心肌断层显像检查,然后行经皮冠脉介入治疗。根据GMPI所测静息左室射血分数(LVEF)分为:A组EF≥50%,15例;B组EF<50%,15例。在行介入治疗8 w后复查静态GMPI检查。结果 30例患者EDV、ESV及MASS在介入治疗8 w后明显降低。EF和CO介入治疗8 w后明显提高(P<0.01)。GMPI对单支、双支、三支病变检出的阳性率分别为83.3%(10/12)、90%(9/10)、87.5%(7/8)。A组介入治疗前后灌注减低节段的改善数明显高于B组(P<0.05)。结论 GMPI对AM I患者心肌血流灌注及心功能的评价具有重要的临床价值;AM I心功能正常组与心功能异常组比较,介入治疗后心肌血流灌注及心功能明显改善。
