Abstract Objective To study the appearance of coronary atherosclerosis in asymptomatic subjects on dual-source computed tomography angiography (CTA) and determine the morbidity prevalence of coronary atherosclerosis among asymptomatic people. Methods A total of 1970 asymptomatic subjects without prior history of CHD and diabetes underwent coronary CTA. The status of coronary atherosclerosis was described. The differences of luminal stenosis, number of involved branches, lesion involving left main artery, segment involvement were analyzed by CT. Results Of 1970 cases, there were 1245 (63.20%) with coronary atherosclerosis. There are 1069 (66.65%) with coronary atherosclerosis among 1603 males and 176(48.09%) among 367 females. In each age group, grade I was the highest incidence of vascular luminal stenosis(60.17％,54.00％;56.67％,52.33％). Gender and age were associated with the progress of atherosclerotic plaque. Conclusions CT angiography provides important information about luminal stenosis and plaque burden in one scan noninvasively and accurately. In asymptomatic non-diabetic population, the conventional risk factors are correlated with CT findings, but still limited in predicting luminal stenosis and plaque burden.
