Key result
Multislice computed tomographic angiography detected plaques in 70 coronary vessels, most commonly the LAD (41.4%), among 50 patients with chest pain or suspected coronary artery disease.
Why the study?
Multislice computed tomographic angiography has been increasingly used to detect coronary artery atherosclerosis, but its accuracy required evaluation.
Does multislice computed tomographic angiography accurately assess coronary artery atherosclerosis in patients with chest pain or suspected coronary artery disease?

Does multislice computed tomographic angiography accurately assess coronary artery atherosclerosis in patients with chest pain or suspected coronary artery disease?
Multislice computed tomography is a valuable, non-invasive method for evaluating coronary artery atherosclerosis and plaque distribution in patients with suspected CAD.
Supports non-invasive plaque evaluation in suspected CAD; leaves open validation of accuracy versus invasive angiography.
Background: Multislice computed tomographic angiography (MCTA) has been increasingly used to detect and diagnose coronary artery atherosclerosis (CAD) due to the small size and tortuous, continuous courses of the coronary arteries, which are closely related to the cardiac chambers. Objective: This study aimed to evaluate the accuracy of MCTA in assessing coronary artery atherosclerosis. Patients and Methods: Fifty patients attending our university hospital with chest pain or suspected coronary artery disease were scheduled for an elective evaluation of coronary artery atherosclerosis. The evaluation was performed using MCTA, and the coronary artery calcium score (CACS) was analyzed and quantified. Results: Of the 50 patients (35 males and 15 females, with a mean age of 56 years) who reported recent onset of chest pain, 15 patients (30%) had normal coronary computed tomographic angiography (CTCA), 15 patients (30%) had non-significant CAD, and 4 patients (8%) had dense coronary calcification. Additionally, 15 patients (30%) had a CACS of 0, with 3 (20%) of these patients showing non-significant CAD, and 12 patients (80%) having normal CTCA. Among the ten patients with a CACS of 1-99, 3 (30%) had significant CAD. Among 20 patients with a CACS of 100-399, 12 (60%) had significant CAD, and one patient with a CACS of 400-999 had substantial CAD. Plaques were detected in 70 coronary vessels, with the left anterior descending (LAD) artery being the most commonly affected (29/70, 41.4%), followed by the right coronary artery (RCA) at 28.5% (20/70), the left circumflex artery (LCx) at 17% (12/70), and the left main (LM) artery at 2.8% (2/70). Conclusion: Multislice computed tomography is a valuable, non-invasive method for evaluating coronary artery atherosclerosis.
