Abstract |

Coronary artery disease (CAD) is the important cause
of death in the world. The aim of the study was to
determine the diagnostic role of 64 multi-slice
computed tomography (MSCT) in the detection of
(CAD). A total of 31 patients (22 Males, 9 Females),
their mean age is 49.4±12.2 years old ranged from
(29-83 years) suspected to have coronary artery
disease undergoing MSCT angiography were included.
Gated coronary, Post-processing techniques were
carried out to assess the presence of coronary
artery disease. CAD was present in coronary artery
in 16 patients (51%). All right coronary artery,
second diagonal branch, first Marginal branch, Left
anterior descending, circumflex and first diagonal
branch were affected, with maximum calcified plaques
act 35.7%, non-calcified plaques 41.7%, mixed plaques
66.6%, diffuse disease 23% and stenosis 33.3%. In
Cardiac Structure Morphology changes were seen in
(50%) of the patients. The average coronary artery
calcification score (CAC) was 266.9 Agatston ranged
from 0-1552. (44%) of the patients had an Agatston
score ≤ 10, (31%) ≤ 400 and (19%) ≤ 1000 and (6%) ≥
1000 Agatston. CAC is significant at P values
0.05 and 0.01 in the presence of stenosis, diffused
diseases, mixed plaques and calcified plaques. The
correlation is not significant between the
morphological changes detected and the calcium score
values, the presence of stenosis and diffused
diseases. The study corroborates that 64-slice MSCT
is a reliable, non-invasive, appropriate tool for
diagnosing patients with CAD.
