颈动脉内膜—中层厚度的超声评价与冠心病相关性研究

The Investigation of Correlation Between the Carotid Artery's Intima-Media Thickness and Coronary Arteriosclerotic Heart Disease by Ultrasonic Diagnosis

目的观察颈动脉内膜-中层厚度(intima-media thickness,IMT)和冠状动脉粥样硬化性心脏病(coronaryarteriosclerotic heart disease,CAD)的关系。方法将65例患者根据冠状动脉造影结果分为对照组与冠心病组。并测量这些患者的IMT及斑块的形态。结果CAD各组颈动脉的IMT、斑块发生率与对照组相比明显增高,(P<0.05);多支病变组颈动脉的IMT、钙化斑块发生率明显高于单支病变组,(P<0.05);颈动脉IMT值与CAD具有明显相关性。结论在CAD患者及具有其危险因素人群中,进行颈动脉的IMT高频超声检查,可间接反映冠状动脉情况,并且有助于对冠脉狭窄程度作出判断,可成为早期诊断CAD的间接指标。

Objective To study the correlation between carotid artery＇s intima- media thickness and coronary arteriosclerotic heart disease. Methods 65 patients were divided into two groups according to the results of angiography. The examination was per- formed by using a GEVV3 device and the intima - media thickness was measured. Results Carotid artery＇s IMT and the incidence of mottling in CAD groups were significantly higher than that in normal groups （ P 〈 0. 05 ）, carotid artery＇s IMT and the incidence of Cal- cification mottling in multi - vessel disease groups were significantly higher than that in single vessel disease groups （ P 〈 0. 05 ）. Posi- tively statistical significance was obtained in the correlation between the carotid artery＇s IMT and CAD. Conclusions Inpatients with CAD and persons with CAD risk factors, examined in carotid using high -frequency ultrasound, the method is very useful in the de- tection of the presence of coronary, atherosclerosis and in the juguement of the extent. It can be a surrogate for diagnosing CAD in earlier period.
