ABSTRACT
<p><b>OBJECTIVE</b>To describe the distribution characteristics of carotid atherosclerosis and to analyze its association with cardiovascular risk factors in middle-aged and elderly Chinese.</p><p><b>METHODS</b>In 2007, the second cross-sectional examination for cardiovascular risk factors and B-mode ultrasound imaging on carotid arteries were performed in a Chinese population consisting of 2681 subjects aged 43-81 years old from two cohorts participants of the People's Republic of China/United States of America collaborative study (USA-PRC study) and the Chinese multi-provincial cohort study (CMCS). The association of cardiovascular risk factors with intima-media thickening (ITM) and plaque of carotid arteries was analyzed.</p><p><b>RESULTS</b>(1) The mean intima-media thickening (Mean-IMT) of carotid artery was 0.68 mm, the maximal intima-media thickening (Max-IMT) was 1.07 mm. (2) The prevalence rate of carotid plaque was 60.3% in all subjects. As for the different sites of carotid arteries, the plaque prevalence rate at carotid bulb was 61.2% for male and 51.6% for female (chi2 = 23.44, P < 0.01), and at the internal carotid artery was 24.7% for male and 12.2% for female (chi2 = 69.57, P < 0.01), at the common carotid artery was 20.9% for male and 13.8% for female (chi2 = 23.18, P < 0.01). (3) After adjusting for age and other cardiovascular risk factors, the Mean-IMT and Max-IMT increased with elevated levels of systolic blood pressure, plasma glucose and low density lipoproteins cholesterol (LDL-C) (all P < 0.05). Hypertension, diabetes, smoking and high LDL-C (P < 0.05) were independent predict factors for the risk of carotid plaque.</p><p><b>CONCLUSION</b>The carotid atherosclerosis was common in middle and older age Chinese and was positively associated with classical cardiovascular disease risk factors.</p>
