急诊^(99m)Tc-MIBI心肌显像在不典型急性心肌梗塞诊断及溶栓治疗中的应用(附5例报告)

The application of emergency 99m Tc MIBI myocardial imaging in the diagnosis of atypical acute myocardial infarction and during the thrombolytic therapy (five case reports)

为探讨急诊９９ｍＴｃ甲氧基异丁基异腈（ＭＩＢＩ）心肌断层显像在不典型急性心肌梗塞（ＡＭＩ）诊断及溶栓治疗中的价值，对５例不典型ＡＭＩ患者静脉注射９９ｍＴｃＭＩＢＩ后２小时进行心肌断层显像。结果，５例患者均明确了诊断，其中２例在６小时内进行了溶栓治疗，通过第二次心肌显像，支持临床冠状动脉再通判断。因此，急诊９９ｍＴｃＭＩＢＩ心肌显像对不典型ＡＭＩ的诊断具有特殊的价值；同时，对判断溶栓疗效，估价预后也具有一定的意义。

PURPOSE Discussion the application of emergency 99m Tc MIBI myocardial imaging in the diagnosis of atypical AMI and during the thrombolytic therapy METHODS Myocardial imaging was performed at 2 hours after injection of 99m Tc MIBI RESULTS We performed emergency myocardial imaging in five atypical AMIs and confirmed the diagnosis in time Meanwhile, 2 of them proceeded thrombolytic therapy in due time Repeat myocardial imaging supported the recanalization of coronery artery CONCLUSIONS 99m Tc myocardial imaging has its special application for the diagnosis of atypical AMI Besides, it also has certain significance for the judgement of thrombolytic effect and its prognosis
