目的 探讨颈动脉粥样硬化与冠心病之间的关系。方法 采用高频超声对 72例因急性心肌梗死、心绞痛及胸痛待查而入院接受冠状动脉造影的病人进行颈动脉检查 ,根据冠状动脉造影结果分为正常冠状动脉组(A组 )和冠状动脉病变组 (分别为单支病变组B1、双支病变组B2、三支病变组B3) ,采用高频超声探测双侧颈总动脉、颈内动脉及颈外动脉 ,计算颈动脉斑块积分 ,测量血管后壁内中膜厚度 (IMT)及颈动脉内血流频谱Vmax。结果 冠状动脉病变组的IMT值明显高于冠状动脉正常组 (P <0 0 5 ) ,冠状动脉三支病变组的IMT值高于单支和双支病变组 (P<0 0 5 ) ,提示颈动脉的病变与冠状动脉病变之间有良好的相关性 (r=0 4 5 ,P <0 0 5 ) ,且外周动脉粥样硬化的程度与冠状动脉病变的程度密切相关。结论 通过对颈动脉的超声检测 ,可以早期发现冠状动脉的病变 ,并可初步预测冠状动脉病变的程度
Objective To investigate the relationship between carotid atherosclerosis and coronary heart disease. Methods 72 cases of patients admitted to hospital for coronary angiography due to acute myocardial infarction, angina pectoris and chest pain were examined by high frequency ultrasound. According to coronary angiography results, they were divided into normal coronary artery group (A group) and coronary artery lesion (B1, T2, B3, B3). The bilateral common carotid artery, internal carotid artery and external carotid artery were detected by high frequency ultrasound, and the carotid artery plaque score was calculated. Intima-media thickness (IMT) and carotid artery blood flow Vmax. Results The IMT of coronary artery disease group was significantly higher than that of normal coronary artery group (P <0.05). The IMT value of three coronary artery disease group was higher than that of single and double vessel disease group (P <0.05), suggesting There was a good correlation between carotid artery lesion and coronary artery lesion (r = 0 45, P 0 05), and the degree of peripheral atherosclerosis was closely related to the degree of coronary lesion. Conclusion Through the detection of carotid artery ultrasound, early detection of coronary lesions, and can be a preliminary prediction of the extent of coronary lesions
