目的通过分析颈动脉粥样硬化与冠心病的关系探讨颈动脉超声对诊断冠心病的临床意义。方法将160例入选对象分为对照组,稳定型心绞痛(SA)组,不稳定型心绞痛(UA)组,急性心肌梗死(AMI)组,每组40例,应用颈动脉超声进行检测。结果冠心病组颈动脉内膜粗糙,多处斑块形成,内中膜厚度增加,内中膜厚度与腔内径比值大于0.1。两组比较差异有统计学意义(P<0.05)。160例中发现颈动脉斑块98例,冠心病组93例,对照组5例。冠心病组动脉斑块的检出率明显高于对照组(P<0.05)。结论颈动脉超声检测对冠心病的预测具有确切的临床意义。
Objective To investigate the clinical significance of carotid artery ultrasound in the diagnosis of coronary heart disease (CHD) by analyzing the relationship between carotid atherosclerosis and coronary heart disease. Methods Totally 160 subjects were divided into control group, SA group, UA group and AMI group. 40 patients in each group were examined by carotid ultrasonography. Results The carotid arteries in the CHD group were rough with multiple plaques and the thickness of the intima increased. The ratio of intima-media thickness to the luminal diameter was greater than 0.1. The difference between the two groups was statistically significant (P <0.05). In 160 cases, 98 cases of carotid artery plaque were found, 93 cases of coronary heart disease and 5 cases of control group. Coronary heart disease plaque detection rate was significantly higher than the control group (P <0.05). Conclusion Carotid artery ultrasound detection of coronary heart disease has a definite clinical significance.
