Abstract |
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. |
