摘要
采用口服硝酸甘油酯(NTG)与静态^(99m)Tc-MIBI心肌灌注断层显像相结合的定量方法,对64例急性心肌梗塞病人进行了存活心肌的测定。静态心肌显像有44.3％(170/384)的节段灌注异常,口含NTG后有57.1％(97/170)的节段心肌灌注得到改善。其中14例接受PTCA的病人,于PTCA前静态显像有27个灌注缺损节段,口服NTG后有51.9％(14/27)的缺损节段得到改善,PTCA后有48.1％(13/27)的缺损节段得到改善。表明本法对心梗后存活心肌的判断是正确的。
To assess myocardial viability of patients with acute myocardial infarction (AMI), 64 patients were studied using nitroglcerin (NTG) interventional 99mTc-MIBI myocardial tomography. Out of 170 segments with hypoperfusion in rest SPECT, 97 segments (57.1%) had improvement of perfusion after oral NTG. In 14 patients who had PTCA, out of 14 segments with an improved perfusion during NTG imaging, 13 segments had improvement after PTCA with an accuracy of 88.9%. In conclusion C SPECT combined with oral NTG imaging may be a useful approach to predicting myocardial viability.
