摘要
目的通过应用彩色多普勒超声诊断仪分析心绞痛患者颈动脉病变的特点,探讨其诊断冠心病的临床价值。方法选择行冠状动脉造影的心绞痛患者85例,根据冠脉造影结果分为0支病变组,1支病变组及多支病变组。测量颈总及颈内动脉后壁的内膜内表面到中膜外表面的距离(IMT),同时注意观察动脉粥样硬化斑块的位置、数量及斑块性质等。结果颈动脉分叉处IMT值各组间均有显著性差异。颈内动脉IMT值在0支病变组与1支病变组间没有显著性差异,但两者均与多支病变组有显著性差异。颈动脉粥样硬化斑块积分各组间均有显著性差异。冠状动脉积分与颈动脉分叉处IMT值及冠状动脉积分与颈动脉硬化斑块积分之间均呈显著性相关。结论通过超声检查观察颈动脉粥样硬化病变的程度可预测冠状动脉病变的情况,对疑有冠心病的患者具有较好的筛选及预测价值。
