颈动脉彩色多普勒超声检查在冠心病早期筛查中的意义

目的 探讨颈动脉彩色多普勒超声检查在冠心病早期筛查中的意义.方法 选取2013年1月至2014年6月赣南医学院第一附属医院就诊的冠心病患者40例.所有患者均经冠状动脉造影证实冠状动脉有一支或多支病变.对照组随机选取本院同期体检健康者40例,对颈动脉进行彩色多普勒超声检查,测量并比较冠心病组与对照组的内,中膜厚度（IMT）及斑块情况.结果 冠心病组颈总动脉、颈动脉分叉处、颈外动脉起始处IMT值均大于对照组,差异均有统计学意义（1.35±0.24） mm比（0.72 ±0.13）mm,（1.61±0.31）mm比（0.76±0.17）mm,（1.18 ±0.21）mm比（0.70 ±0.12）mm,均P＜0.05];颈内动脉起始处IMT值和斑块积分亦大于对照组,差异有统计学意义（1.20 ±0.22）mm比（0.68 ±0.12）mm,（2.2±0.6）分比（0.6±0.2）分,均P＜0.01].结论 颈动脉IMT及斑块形成可以反映动脉粥样硬化,对预测冠心病有一定临床意义.

The significance of carotid ultrasound in the early screening of coronary heart disease

Objective To investigate the significance of carotid ultrasound in the early screening of coronary heart disease.Methods Totoally 40 patients with coronary heart disease from January 2013 to June 2014 were enrolled; all cases were excluded with hypertension,cerebral thrombosis,diabetes that could cause arteriosclerosis.All patients were confirmed by coronary angiography.Control group had 40 cases of healthy people ; carotid artery intima media thickness （IMT） and plaques by color ultrasonography were compared.Results The common carotid artery,the carotid artery bifurcation and external carotid artery IMT value had significant differences （1.35±0.24）mmvs（0.72±0.13）mm,（1.61 ±0.31）mmvs （0.76±0.17）mm,（1.18±0.21）mm vs （0.70 ± 0.12） mm,P 〈 0.05] ; there was statistical significance in carotid artery IMT value and plaque score difference （1.20 ±0.22）mm vs（0.68 ±0.12）mm,（2.2 ±0.6） scores vs （0.6 ±0.2） scores,P〈0.01].Conclusions Carotid IMT and plaque formation can reflect atherosclerosis and have certain clinical significance to predict coronary heart disease.
