摘要 目的评价超声检测颈动脉结构的改变与冠状动脉病变及其严重程度和心血管病危险因素的关系。方法根据冠状动脉造影结果,将76例临床怀疑或已确诊为冠心病的患者分为冠心病组(58例)和正常对照组(18例),用高分辨率超声检测所有患者的双侧颈动脉(CCA)内径、内膜-中膜厚度(IMT)、斑块及其数量,计算颈动脉几何形状改变。结果颈动脉斑块发生率、内径、IMT、颈动脉半径和IMT的比值(R/IMT)均和年龄增长显著相关。结论超声检测的颈动脉结构与弹性特征改变与年龄增长显著相关。超声检测的CCA斑块、IMT可较准确的预测冠心病危险性。超声检测的CCA结构及弹性特征的变化可与预测冠脉病变的严重程度,但预测价值不高。
