Quality of CT in Diagnoses Atherosclerosis

Talal Mohammed A Al Amrani ^[2] | Hassan A Elazeem Gad ^[5]

Abstract: Introduction: The primary endpoint of this study was to determine Quality of CT In diagnoses atherosclerosis. Secondary endpoints were to evaluate the risk factors and determine the predictors of PVA. Methods: The presence of atherosclerotic disease was assessed using ultrasonographic vascular examination in 20 asymptomatic patients. All patients with presence of stenosis over 55 % and moderate-to-severe cardiovascular risk profile underwent CCTA to identify atherosclerotic. Results: Among 20 participants, 5 patients had no evidence of atherosclerotic plaque while 15 patients had atherosclerotic plaque. Of 15 patients with atherosclerotic plaque, 10 patients had single vessel disease, 3 patients had double vessel disease and 2 patients had triple vessel disease; and among these patients, those who also presented with stenosis over 55 % underwent CCTA. Coronary stenoses found included normal (6 %), haemodynamically insignificant lesions (30 %), significant lesions (25 %) and total artery occlusion (3 %). Based on the coronary vessel involved, they were categorised as single coronary disease (41.0 %), double coronary disease (42.0 %) and triple coronary disease (17.0 %). CACS was significantly higher in patients with double vessel disease or triple vessel disease when compared to those with single vessel disease. Conclusion: Our study confirmed not only the high sensitivity of CCTA for highlighting CAD but also its negative predictive value for excluding the presence of coronary stenosis or ischaemia. Good correlation was found between PVA and CACS, and the risk factors for PVA were confirmed.
