目的分别分析心外膜脂肪 (epicardial adipose tissue，EAT)、心周脂肪(Pericardial adipose tissue, PAT)与冠状动脉粥样硬化之间的关系， 比较其优劣。方法 对104例受检者进行 CTA检查，在钙化积分图像基础上测量 心外膜脂肪和心周脂肪体积，分析两者 之间的关系及各自与冠状动脉粥样硬化 间的关系。结果 EAT体积与PAT体积具 有显著相关性(r=0.877,P<0.01)；两 者与冠状动脉粥样硬化Gensini积分间 均具有相关性(P<0.05)；2支、3支冠 脉病变的EAT、PAT体积大于单支病变 (P<0.05)，2支、3支之间差异无统计学 意义(P>0.05)；ROC曲线提示两者对冠状 动脉粥样硬化的诊断价值相仿。结论 EAT 体积与PAT体积显著相关，对冠状动脉粥 样硬化均具有一定的诊断价值。

Objective To analyze the relationship between epicardial adipose tissue (EAT) and pericardial adipose tissue (PAT) with coronary atherosclerosis. Methods 104 participants were given CTA inspection. EAT and PAT were measured according to the images of calcification score, and the relationships between them as well as between coronary atherosclerosis with EAT and PAT were analyzed. Results There was a significant correlation between EAT volume and PAT volume; they had a certain relationship with Gensini scores - the scores of coronary atherosclerosis; in patients with two or three branches of coronary artery lesions, the EAT and PAT volumes were larger than that in patients with single lesion, and there was no statistically significant difference between the two and three branches; ROC curve suggested that the diagnostic values of EAT and CAT on coronary atherosclerosis were similar. Conclusion EAT volume is significantly associated with PAT volume, and both of them have a certain diagnosis value to the diagnosis of coronary atherosclerosis.
