Abstract:
This study was designed to define the role of computed tomography coronary
angiography (CTA) in the diagnosis of patients with chest pain and suspected to
have coronary artery disease (CAD) by measuring the calcium scoring in the
coronary arteries (CAC) and correlate the results with the (CTA) findings and
coronary arteries plaque types. A 101 patients (59 male, 42 female; mean age,
58.98 years) underwent (CTA). Quantitative coronary angiography calcium
scoring (Agatston) was measured in right coronary artery (RCA), left anterior
descending artery (LAD), left circumflex coronary artery (LCFX). The main
finding of this study was; Plaque types were calcified in 29.7%, non-calcified in
10.9%, mixed in 8.9% and soft plaque in 1.0%. (CTA) findings were mild,
moderate and severe atherosclerosis, coronary arteries stenosis, total occlusion and
pericarditis. A significant relationship was noticed between the calcium scoring
values and the (CTA) findings in both (LAD) and (RCA) at p value˂0.05, with no
significant relation between the plaque type and calcium scoring Agatston values
in (RCA) and (LCFX) was identified.
Finally (CAC) offers identifying the patients intended to have cardiac events,
diagnosis of coronary arteries lesions and characterizing the plaque pattern .It is
believable that measurements of calcium score will provide an acknowledged
analytical radiological tool for the diagnoses of (CAD).
