Objectives It is unclear whether an individual carotid arterial wall thickness is correlated with cardiovascular risk factors like carotid intima-media thickness (IMT). We assessed the correlation of individual arterial wall (intima (IT), media (MT), and IMT) thickness of carotid artery with cardiovascular risk factors in patients with coronary atherosclerosis. Methods Study subjects consisted of 984 consecutive patients (533 males (54.2%), mean 59.9짹11.4 years old) who underwent coronary angiography. Each arterial wall thickness (IT, MT, IMT) of the carotid artery was measured using high-resolution ultrasound and B-mode ultrasound processing. Results Mean carotid IMT, IT and MT were 0.74짹0.12mm, 0.34짹0.03mm and 0.45짹0.10mm, respectively. Carotid IMT was correlated with age (r=0.29, p<0.001), fasting blood sugar (FBS) (r=0.13, p=0.001), total cholesterol (r=0.12, p=0.002) and LDL-cholesterol (r=0.17, p<0.001). IT was correlated with age (r=0.20, p<0.001). MT was correlated with age (0.17, p<0.001), FBS (r=0.11, p=0.014), total cholesterol (r=0.15, p<0.001) and LDL-cholesterol (r=0.22, p<0.001). IMT, IT, and MT was thicker in patients with hypertension (0.77짹0.13mm vs. 0.73짹0.12mm, 0.34짹0.03mm vs. 0.33짹0.03mm and 0.48짹0.10mm vs. 0.44짹0.09mm, p<0.001, p=0.028 and p<0.001, respectively) and diabetes mellitus (0.75짹0.12mm vs. 0.73짹0.12mm, 0.34짹0.03mm vs. 0.33짹0.03mm and 0.46짹0.10mm vs. 0.44짹0.10mm, p=0.002, p=0.003 and p<0.014, respectively). On multivariated analysis, IMT was correlated with age (棺=0.018, p<0.001), hypertension (棺=0.019, p=0.042) and LDL-cholesterol (棺=0.001, p<0.001), IT was correlated with age (棺=0.001, p<0.001) and MT was correlated with age (棺=0.001, p=0.001) and LDL-cholesterol (棺=0.001, p<0.001). Conclusions This study showed that IMT and MT were correlated with cardiovascular risk factors including age, fasting blood sugar, total cholesterol and LDL cholesterol, whereas IT was only correlated with age.
