老年冠心病患者颈动脉内-中膜厚度的超声测定（附60例报告）

目的通过分析颈动脉内-中膜厚度与老年冠心病的关系,探讨颈动脉超声在老年冠心病诊断中的临床意义。方法将60例入选的老年冠心病患者分为稳定型心绞痛（SA）组,不稳定型心绞痛（UA）组,急性心肌梗死（AMI）组,每组20例,并设立对照组20例,分别给予超声检测颈动脉内-中膜厚度（IMT）,进行分析比较。同时对48例老年冠心病患者进行冠脉造影检查,根据造影结果分为正常组11例,单支病变组16例,多支病变组21例,比较不同组间IMT水平的差异。结果老年冠心病患者颈动脉IMT较正常对照组有显著增厚（P〈0.01）,且在冠心病不同严重程度组中颈动脉IMT也存在一定的差异。对冠脉造影正常组与单支病变、多支病变组间IMT进行比较,结果也存在统计学差异（P〈0.05）。结论通过颈动脉超声测定颈动脉IMT水平,对老年冠心病的预测具有一定的临床意义。

Ultrasonic measurements of carotid intima-media thickness in senile patients with coronary heart disease: a report of 60 cases

Objective To evaluate the clinical significance of carotid ultrasonography for diagnosing coronary heart disease（CHD） in senile patients through analyzing the relationship between carotid intima-media thickness and CHD in senile patients. Methods Sixty senile patients with CHD were divided into stable angina group（n=20） ,unstsble angina group（n=20） ,and acute myocardial infarction group（n=20） . Twenty healthy subjects were taken as normal control. Carotid intima-media thickness（IMT） was measured by ultrasound. The values of IMT in different groups were compared each other. Simultaneously,the ultrasonic results of carotid arteries were compared with those of coronary arteriography. Results Compared with control group,patients with CHD were found to have significantly increased carotid IMT and the IMT in the patients with acute coronary syndrome was greater than that in the patients with stable angina（P 0.01） . Further,IMT values in patients with single-branch-lesion and poly-branch-lesion were greater than those in control group（P 0.05） . Conclusion Detecting carotid IMT by ultrasonography has certain clinical significance for predicting CHD in senile patients.
