摘要 目的探讨冠心病患者颈动脉内膜中层厚度(IMT)及斑块超声改变的特点及其关系。方法127例临床诊断为冠心病的患者,经冠脉造影检查后分为2组:冠心病组86例,非冠心病组(对照组)41例,用高分辨率超声心动图分别测量两组双侧颈总动脉的IMT及斑块情况,探讨两组患者的颈总动脉IMT及斑块发生率与冠状动脉受累支数及程度的关系。结果①冠心病组的平均颈总动脉IMT及斑块发生率显著高于非冠心病组(P<0.01),多支病变组高于单支病变组(P<0.05)。②平均颈总动脉IMT与冠心病患者冠状动脉狭窄程度无显著相关(r=0.164,P>0.05),冠心病患者中有斑块者的冠状动脉狭窄程度显著重于无斑块者(P<0.05),斑块积分与冠状动脉狭窄程度呈正相关关系(r=0.448,P<0.01)。③斑块的发生对判断冠心病的敏感性为52.3%,特异性90.2%。结论超声测量颈总动脉IMT,斑块可靠、易测,可间接判断冠心病的有无及其病变范围和严重程度。
