颈动脉超声对冠心病的预测应用价值

The Application of Carotid Ultrasonography in Predication of Coronary Heart Diesease

目的探讨颈动脉内中膜厚度(IMT)及斑块与冠状动脉造影(CAG)结果的相关性,了解IMT和斑块在预测冠心病中的价值。方法129例经CAG分为冠心病组和非冠心病组,超声观察颈动脉IMT和有无斑块,与CAG对照。结果非冠心病组和冠心病组比较颈动脉IMT和斑块均存在显著性差异(P<0.05),颈动脉IMT对冠心病诊断有较高的敏感性和特异性。结论颈动脉超声可作为冠心病诊断的一项重要辅助检查手段。

Objective To investigate the relationshop between carotid artery intime-media thickness（IMT） and plaque with coronary heart disease（CHD）.Methods 129 patients with suspected CHD were divided into two groups with selected coronary angiography：Group CHD and Group NCHD（without CHD）.Group CHD was subdivded into three groups according to the coronary branches involved.The IMT and plaques of carotid arteries were measured in all patients with ultrasonography.Results The carotid artery IMT,plaque were higher statistically in Group CHD than those in Group NCHD.Conclusion Carotid artery IMT plaque were related to coronary heart disease significantly,which can be used to evaluate CHD and its severity.
