中文摘要：

目的探讨心外膜脂肪组织（EAT）与颈总动脉内中膜厚度（CIMT）、冠心病的相关性，进一步分析EAT预测冠心病的意义。方法入选确诊冠心病需行冠脉造影住院患者160例（其中非冠心病86例，冠心病74例），入院后10d内彩超检测EAT厚度、CIMT厚度，分析EAT厚度与CIMT厚度、冠心病的相关性。结果相关性分析显示，EAT厚度与CIMT有较好的相关性（r=0．79，P〈0．001）；冠心病组EAT、CIMT较非冠心病组明显高[（8．65±1．45）vs（6．30±1．53）mm；（1．17±0．21）VS（0．83±0．19）mm；均P〈0．01）]；CIMT≥0．92mm预测冠一tL,病的敏感度、特异度、Youden指数分别为0．81、0．78、0．59，EAT≥7．24mm预测冠心病的敏感度、特异度分别为0．84、0．80、0．64。结论超声检测EAT和CIMT可作为冠心病的预测指标。‘

英文摘要：

Objective To explore the correlation among epicardial adipose tissue （EAT） , carotid artery intima medial thickeness （CIMT） and coronary heart disease（CAD） , further analyze the significance of EAT to predict CAD. Methods 160 hospitalized patients with CAD underwent coronary angiography were consecutive selected, including 86 cases with non-CAD, 74 cases with CAD, within admis- sion 10 d, the EAT and CIMT thicknesses were measured by color Doppler ultrasound. Results Correlation analysis showed,EAT thickness had good eorrelation with CIMT （ r = O. 79 ;P 〈 0. 001 ）. Compared with those of non-CAD group, EAT, CIMT of CAD group were significant- ly higher（ （8.65 ± 1.45） vs. （6. 30 ± 1.53） mm; （ 1.17 ±0. 21 ） vs. （0. 83 ±0. 19） ram, P 〈0. 0017. For patients with coronary artery stenosis 〉 50%, the sensitivity, specificity and Youden index of CIMT ≥ 0. 92 mm were 0. 81,0. 78,0. 59, respectively; the sensitivity, spe- cificity and Youden index of EAT ≥ 7.24 mm were 0. 84,0. 80,0, 64, respectively. Conclusions Color Doppler detection of EAT and CI MT may have the Potential to be a oredictor of risk factors for CAD and arteriosclerosis.
