BACKGROUND: The aim of this study was to determine the association between carotid intima-media thickness (IMT) and newly developed 10-year atherosclerotic cardiovascular disease (ASCVD) risk score. METHODS: Participants were 201 Korean adults who underwent carotid ultrasonography at the Health Promotion Center of the Eulji General Hospital. We obtained information about medical history and lifestyle, and conducted laboratory tests. Carotid IMT by B-mode ultrasonography was measured. Carotid injury was considered present when the maximum carotid IMT was > or =0.9 mm or when arteriosclerotic plaques were detected. The 10-year ASCVD risk score was calculated using the 2013 American College of Cardiology/American Heart Association guidelines. RESULTS: Men had higher 10-year ASCVD risk score than did women (mean+/-standard deviation: 7.15+/-6.04 vs. 2.53+/-3.67, respectively; P<0.001). Ten-year ASCVD risk was significantly correlated with right maximum carotid IMT (r=0.307), left maximum carotid IMT (r=0.230), right mean carotid IMT (r=0.322), and left mean carotid IMT (r=0.264). The group with high 10-year ASCVD risk were at even higher risk of carotid injury than were the group with low 10-year ASCVD risk (odds ratio, 2.201; 95% confidence interval, 1.162-4.1706; P=0.019). Only 10-year ASCVD risk score was significantly associated with carotid injury (odds ratio, 4.104; 95% confidence interval, 1.570-10.729). Variables that were not included in the 10-year ASCVD risk score were not significantly associated with carotid injury. CONCLUSION: The findings of this study suggest that 10-year ASCVD risk score is associated with carotid injury.
