Coronary and Carotid Arterial Calcification: The Relativity and Risk Factors / 实用放射学杂志

ABSTRACT

Objective To determine the correlation between coronary artery calcium score (CACS) and carotid calcification, and their risk factors. Methods 162 cases underwent coronary and carotid pre-contrast CT scan with dual-source CT scanner within 2 weeks. The reconstructed parameters were the same. The calcifications of coronary and carotid arteriae were quantified by calculating the Agatston score. The main risk factors such as age, sex, hypertension, total cholesterol, low-density-lipoprotein cholesterol (LDL), high-density-lipoprotein cholesterol (HDL), diabetes, smoking and coronary heart disease history were recorded. The CACS and carotid calcium scores were comparatively analyzed using Spearman's correlative analysis. The relativity between the risk factors and CACS scores, carotid calcium scores. Results In 162 subjects, there was positive relativity between CACS and carotid cal-cium score(r=0.690, P<0.01). Logistic regression analysis showed that CACS were of relativity with age, diabetes, total cholesterol and LDL cholesterol,otherwise, carotid calcium scores only with age and diabetes. Conclusion There is significant correlation be-tween CACS and carotid calcium score, but their risk factors are not same.
