摘　　要：目的:分析冠心病患者颈动脉粥样硬化(CAS)病变高频超声体表标识表现。方法:连续选择521例接受冠状动脉造影的住院患者,造影后同时进行颈部动脉体表血管彩色多普勒超声检查。结果:521例入选对象中,冠状动脉正常者81例(对照组),确诊冠心病患者440例,其中轻度狭窄组36例、中度狭窄组90例和重度狭窄组314例。冠心病各组的内膜-中层厚度(IMT)、IMT增厚率、斑块总面积和斑块发生率均明显高于对照组,冠心病中、重度狭窄组的IMT和斑块总面积也显著多于轻度狭窄组(P<0.05～0.01)。冠心病各组各种斑块明显多于对照组(P<0.05～0.01),中及重度狭窄组软斑、硬斑数显著多于轻度狭窄组(P均<0.05)。在CAS超声分级比较中,冠心病各组狭窄超声级别均明显多于对照组,同时重度狭窄组C、D级例数明显多于后者(P<0.05～0.01)。结论:冠心病患者颈部动脉病灶超声体表标识可作为冠状动脉粥样硬化严重程度的间接判定指标。Objective： To analyze the surface marking of carotid atherosclerosis （GAS） in patients with coronary heart disease. Methods： A total of 521 cases of consecutive patients were chosen to check the coronary angiography, and the vascular surface of carotid was examine with color Doppler ultrasound. Results： In 521 cases, 81 cases were with normal coronary arteries （control group）, 440 patients were confirmed with coronary artery disease, of which 36 cases were mild stenosis group, 90 cases were moderate stenosis and 314 cases severe stenosis （group）. The intima-media thickness （IMT）, intima-media thickening rate, plaque area and plaque incident rate of carotid in each CHD group were significantly higher than those of control group, the IMT and plaque area in CHD patients with moderate stenosis and severe stenosis were also much more than those of mild stenosis group （P〈0. 05-〈0.01）. The various kinds pathological change in each CHD group were significantly higher than those of control group （P〈0. 05-〈0. 01）, and soft plaque, hard plaque in CHD patients with moderate stenosis and severe stenosis were also much more than those of mild stenosis group （P〈0. 05）. The classifications of CAS in each CHD group were significantly higher than those of control group, and the numbers of C class and D class in CHD patients with moderate stenosis and severe stenosis were more than those of mild stenosis group （P〈0. 05-〈0. 01）. Conclusion.. The carotid ultrasound mark in coronary heart patients can be used as indirect indicators of coronary artery atherosclerosis.
