N/A The coronary collateral vessels have revealed their significance in terms of reduction of infarct size, preservation left ventricular function, and prevention of left ventricular aneurysm in patients with myocardial infarction. The purpose of this study were to evaluated the relation between collateral circulation and 99mTc-MIBI Heart SPECT in patient with acute myocardial infarction and their clinical significance. The fifty six MI patients with antegrade TIMI perfusion grade 0 and 1 were studied. The pat#ients #were classified into two groups; Group I inclueded 30 patients with grade 2, 3 Collateral flow. Group II inclueded 26 patients with grade 0, 1 Collateral flow. Collateral filling were graded from 0 to 3; 0- none, 1- Filling of side branch only, 2- Partial filling of the epicardial segment, 3- Complete filling of epicardial segment. Clinical variables, left ventricular function, 99mTc-MIBI Heart SPECT were analyzed with angiographic finding. Results were following: 1) Collateral visualization was found to be greater in patient with invoivement of right coronary artery (RCA). The callateral development site of infarct related artery was RCA 15 cases, left anterior descending artery (LAD) 10 cases, left circumflex artery (LCX) 5 cases, and the collateral circulation from LAD to RCA was 13 cases (40.6%). 2) There was a tendency to be decreased in peak CK activity with group I . 3) The presence of good collateral channels was more frequently 99mTc-MIBI reversible perfusion defect (83.4% vs 15.3%, p<0.05). 4) No differences af left ventrieular end diastolic volume (LVEDV), left ventricular end systolic volume (LVESV), ejection fraction (EF) were noted between group I and group II. The presence of good collateral channels did affect the frequency of occurrence of 99mTc-MlBI reversible perfusion defect.

N/A Among 64 patients with acute myocardial infarction who underwent coronary angiogrphy, 7 patients (10.9%)showed normal coronary artery. Six patients were men and 1 patient was female. The mean age of patients were 31.1±3.9 years. Among the risk factors of coronary heart disease, smoking was most probable factor in patients with acute myocardial infarction with normal coronary angiography. Tc-99m-MIBI heart SPECT performed 5 of 7 patients and showed that it could be used in diagnosis, localization, extent of infarct area in patients with acute myocardial infarction with normal coronary angiography. But follow up Tc-99m-MIBI heart SPECT study will be needed to define the ability of myocardial viability in this patients.
