冠心病患者颈动脉超声检测的临床意义

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120例入选对象分为对照组,稳定性心绞痛(SA)组,不稳定性心绞痛(UA)组,急性心肌梗死(AMI)组,每组30例,分别给予超声检测颈动脉内-中膜厚度(IMT),同时测定3组冠脉造影结果:正常组21例,单支病变组18例,多支病变组29例。结果冠心病患者IMT较正常对照组有显著增厚(P<0.01),且冠脉造影正常组与单支、多支病变组间亦存在显著性差异(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。

Clinical significance of carotid arteries ultrasonography for diagnosing coronary heart disease

Objective To observe the clinical significance of carotid arteries ultrasonography for diagnosing coronary heart disease through analyzing the relationship between carotid arteries atherosclerosis and coronary heart disease.Methods A hundred and twenty subjects were divided into control group(n=30),stable angina group(n=30),unstsble angina group(n=30)and acute myocardial infarction group(n=30).Carotid artery intima-media thickness(IMT)was measured by ultrasound.The level of IMT in different groups was compared.Simultaneously,the result of carotid arteries ultrasound was compared with that of coronary arteriography.Results Compared with control group,patients with coronary heart disease were found to have significantly increased carotid IMT and the IMT in the patients with acute coronary syndrome was greater than in those with stable angina(P< 0.01).Further,IMT level in patients with single-branch-lesion and poly-branch-lesion was higher than in control group(P< 0.05).Conclusions Detecting carotid atherosclerosis by ultrasonography has definite clinical significance for predicting coronary heart disease.
