高频超声探查颈动脉预测冠状动脉病变

目的以颈动脉为窗口，探讨颈动脉与冠状动脉硬化间关系。方法用高频超声探查冠状动脉多支病变组，一支病变组与对照组的颈动脉内中膜厚度值(IMT)，斑块分级。结果三组IMT值及斑块分级存在显著差异。以斑块存在为预测冠脉病变的阳性指标，敏感性为83％，持异性为77％。1ogistic回归分析发现斑块为预测冠状动脉粥样硬化性。0脏病(CAHD)的最有效的阳性指标。结论高频超声探查颈动脉可预测冠状动脉病变的存在及严重程度。

Predicting the Coronary Artery Disease Risk Using the Carotid Artery Ultrasonography

Objective To define the relationship between the carotid artery and the coronary artery using the carotid ultrasonography. Methods The intimal media thickness (IMT) value and grade of plaque in carotid artery were measured by high frequency ultrasound in patients of control group and coronary artery disease group. Results There were significant differences of carotid artery IMT value and the grade of plaque among the control, one vessel stenosis and multi vessel stenosis groups. The sensitivity and specificity predicting the coronary artery atherosclerosis risk by the carotid plaque were 88% and 62%. Among all the clinical coronary atherosclerosis artery disease risk factors, carotidplaque was the most predictive. Conclusion Carotid artery atherosclerotic lesions can predict the existence and severity of the coronary artery atherosclerosis. [
