为观察急性心肌梗塞（ＡＭＩ）早期静脉溶栓的疗效，应用静态９９ｍＴｃ甲氧基异丁基异腈心肌断层显像，对２２例ＡＭＩ病人进行了观察。结果显示，９例溶栓再通病人由溶栓前平均９１±３３分降至３７±２２分（ｔ＝４０８５，Ｐ＜００１）。溶栓后２０个缺损节段中６个恢复正常，１０个明显改善。而这些节段为ＥＣＧ检查所示的梗塞部位。未溶栓组２次心肌显像变化不大。因此，静息心肌显像可观察ＡＭＩ病人溶栓前后心肌缺血有无改善，也可为判断冠状动脉再通提供影像学基础，具有一定的应用前景。
To observe the effect of early intravenous thrombolysis in patients with acute myocardial infarction (AMI), 22 AMI patients were observed with static 99mTc-methoxyisobutylisonitrile myocardial tomography. The results showed that 9 cases of thrombolytic recanalization from an average of 91 ± 33 before thrombolysis to 3 7 ± 2 2 points (t = 4 085, P <0 01). Six of 20 defect segments returned to normal after thrombolysis and 10 were significantly improved. These segments are the infarct sites shown by the ECG. No myocardial thrombolysis 2 myocardial imaging little change. Therefore, resting myocardial imaging can be observed before and after thrombolytic therapy in AMI patients with or without improvement of myocardial ischemia, coronary artery recanalization can also provide imaging basis, with a certain application prospects.
