颈动脉超声在诊断冠心病合并2型糖尿病中的应用价值

目的探讨颈动脉超声在冠心病合并2型糖尿病中的应用价值。方法将研究对象分为合并2型糖尿病和不合并2型糖尿病的冠心病组，超声观察颈动脉血流参数、内中膜厚度（IMT）及斑块指数（PI），并与冠状动脉造影结果对照。结果与单纯冠心病患者相比，合并2型糖尿病的冠心病患者颈动脉内径和血管阻力指数均增加（P〈0.05），IMT及PI随冠状动脉造影病变程度的增加而显著增加（P〈0．05）。结论颈动脉超声可以间接判断冠心病合并2型糖尿病患者冠状动脉血管病变的严重程度，可作为诊断合并2型糖尿病的冠心病的一项辅助检查方法。

Carotid artery ultrasonography in the diagnosis of coronary heart disease with type 2 diabetes mellitus:analysis of 203 cases

Objective To study the practical value of carotid artery ultrasonography in coronary heart disease （CHD） with type 2 diabetes mellitus. Methods The subjects were divided into coronary heart disease with and without diabetes mellitus groups. Carotid artery blood-stream parameters , intima-media thickness （IMT） and plaque index （PI） were examined by ultrasound. The results of carotid artery ultrasonography were compared with those of coronary angiography. Results Compared with simple CHD patients without type 2 diabetes mellitus, CHD patients with type 2 diabetes mellitus had larger carotid inner-diameter and vessel resistance（P〈0.05） , and its carotid artery IMT and PI were increased with the aggravation of coronary disease（P〈0.05）. Conclusion Carotid artery ultrasonography could be used as an adjuvant method for the diagnosis of coronary heart disease with type 2 diabetes mellitus.
