Background: We evaluated the severity of coronary artery disease and clinical characteristics according to coronary calcium score detected by dual source CT (DSCT). Methods: Patients who were undertaken coronary CT angiography (CTA) using DSCT from Nov 2007 to Jun 2008 were divided into 3 groups according to Agatston score: Group I, ≥400 (n=67); Group II, 100-400 (n=91); Group III, <100 (n=98). Results: Patients in the higher Agatston score group were older and more frequently male. The incidence of risk factors was higher and coronary lesions were more severe in the higher calcium score groups (Table). The Agatston score was positively correlated with diseased vessel number on both CTA (r=0.445, p=0.01) and CAG (r=0.376, p=0.01). Conclusion: Patients with higher coronary calcium score measured by DSCT had more severe coronary disease as well as higher incidence of cardiovascular risk factors.
