颈动脉内-中膜厚度与冠心病的相关性

目的探讨颈动脉内中膜厚度(IMT)及斑块与冠状动脉造影(CAG)的相关性.方法研究对象经CAG分为冠心病组和非冠心病组,超声观察颈动脉IMT及有无斑块形成,与CAG结果对照.结果非冠心病组、冠心病不同分支病变组患者颈动脉IMT及斑块指数和冠状动脉疾病记分随CAG严重程度的增加显著增加(P<0.05～0.01),颈动脉IMT冠状动脉疾病记分呈正相关(r=0.726,P＜0.01).与颈动脉IMT及斑块指数对冠心病诊断有较高的敏感性、特异性、粗一致性和Kappa值.结论颈动脉超声是冠心病诊断的一项重要的辅助检查手段.

Relationship between carotid artery intima-media thickness and coronary artery disease in patients

Objective To observe the relationship between carotid artery intima-media thickness (IMT) and coronary arteriography (CAG). Methods The subjects were divided by CAG into two groups as coronary artery disease and normal group. Carotid artery IMT and the balk of the plaques were examined by ultrasound. The result of carotid artery ultrasound was compared with that of CAG. Results Carotid artery IMT and the plaques index were increased with the aggravation of the coronary disease(P< 0.05 or < 0.01). Carotid artery IMT was closely associated with coronary disease score(r= 0.726,P< 0.01). Carotid artery IMT and the plaques index have a significant predicting sensitivity, specifity and Kappa.Conclusion Carotid arteries ultrasoungraphy is an important method to the diagnosis of coronary artery disease and the window of observation of atherosclerosis.
