Abstract

We did Tc-99m sestamibi myocardial perfusion SPECT in 36 patients with acute myocardial infarction when they arrived at the emergency room. And we compared myocardial perfusion images with ECG findings. Then we obtained the follows. The myocardial infarction by the obstruction of left coronary descending artery and right coronary artery showed a good concordance in the diagnosis and infarction site between myocardial perfusion images and ECG findings. The 7 patients with myocardial infarction by a left circumflex coronary artery showed a perfusion defect in the lateral wall in myocardial perfusion SPECT images. But 4 patients of them showed ST segment elevation, 2 patients showed ST depression and 1 patient showed normal ECG findings. The diagnostic sensitivity of Tc-99m sestamibi myocardial perfusion SPECT was 100% by a qualified analysis. The perfusion defect site in the myocardial perfusion SPECT were con-responded with the infarct related coronary artery in 31 patients which was diagnosed by coronary angiograpy. The size of perfusion defect in the polar map was 31¡¾18%(M¡¾SD), in the myocardial infarction with left anterior descending coronary arery obstruction, 31¡¾13% (M¡¾SD) in the myocardial infarction with right coronary artery obstruction and 25¡¾5.9%(M¡¾SD) in the myocardial infarction on with left circumflex coronary artery obstruction. We concluded that emergency myocardial perfusion SPECT images are useful in the diagnose of myocardial infarction and it's very useful when we are difficult to diagnose with ECG like as lateral wall infarction or left bundle branch block.
