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).
