颈动脉高频超声探查预测高血脂患者冠状动脉病变

目的 :以颈动脉作为“窗口” ,探讨高血脂患者颈动脉粥样硬化斑块与其冠状动脉病变之间关系。方法 :5 3例高血脂患者据冠脉造影检查结果分为阳性组 (2 4例 )和阴性组 (2 9例 )。高频超声探查颈动脉 ,比较两组斑块阳性率、斑块分型、大小和分布。结果 :有冠脉病变的高血脂患者斑块阳性率显著高于阴性组 ,且以复合性斑块为主 ,阴性组以纤维性斑块为主 ,两组斑块大小也存在显著差异。结论 :颈动脉动脉粥样硬化可以反映冠状动脉粥样硬化的有无 ,可作为透视冠状动脉的一个“窗口”。高血脂患者的斑块大小和声像图分型对其冠脉病变有预测作用。

Carotid Artery High-frequency Ultrasound in the Prediction of Coronary Artery Disease In Hypercholesterolemic Patients

Objective To understand the association of carotid artery atheromatous sclerosis with coronary artery disease in hypercholesterolemic patients. Methods 53 hypercholesterolemic patients were divided according the coronary angiography into two groups:positive 24 cases and negative 29 cases.The positive rates,sizes and distribution of the sclerosis were analyzed and compared by high-frequency ultrasound. Results There were significant differences in the occurrence,the type and size of plaque area between the two groups. The sensitivity and the specificity of the coronary artery atherosclerosis by the plaque type were 88% and 62% separately. Conclusion Carotid artery atherosclerotic lesions can suggest the potential presence of coronary artery disease.
