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. |
