颈动脉实时三维超声在冠心病危险评估中的应用价值(1)
【摘要】 目的：探讨实时三维超声技术于颈动脉粥样硬化评估及间接对冠心病的病变程度的评估中的应用价值。方法：将100例疑似冠心病患者分为冠心病组和对照组(非冠心病组)，均行冠脉造影检查，并进行颈动脉二维彩色多普勒超声和实时三维超声检查判断颈动脉斑块类型，分析其与冠状动脉病变支数、冠脉狭窄程度的关系，分析实时三维超声检查在冠心病危险评估中的作用。结果：两组颈动脉斑块比较差异有统计学意义(P<0.05)，且随着冠状动脉病变累及支数的增加，斑块检出率明显增加；多支病变组与单支病变组的颈动脉斑块比较差异有统计学意义(P<0.05)，病变支数越多者，颈动脉斑块发生率越高；且斑块多为软斑块、含有软斑块为主的混合性斑块。实时三维超声对软斑和混合斑检出率在单支病变组及多支病变组与二维超声比较差异均有统计学意义(P<0.05)。因此颈动脉粥样斑块的存在可以预诊冠状动脉粥样硬化的存在，颈动脉粥样硬化与冠状动脉粥样硬化呈明显的相关性。对软斑、混合斑的检出率及斑块表面溃疡检出率方面实时三维与二维超声比较差异有统计学意义(P<0.05)。实时三维超声对颈动脉斑块表面有无溃疡检测优于二维超声。结论：颈动脉实时三维超声检查，可间接评估冠状动脉粥样硬化程度，有效预测患者发生心血管不良事件的几率。

【Abstract】 Objective：To probe the value of using real-time three-dimensional ultrasonography for the evaluation of carotid atherosclerosis and the degree of coronary stenosis of patients with coronary heart disease.Method：A total of 100 patients were suspected coronary heart disease after had being diagnosed by coronary angiography(CAG).They were divided into two groups.All of these patients undertook carotid artery color doppler ultrasonography(2D) and real-time three-dimensional ultrasonography (3D)within CAG diagnosis，and carotid artery plaques were evaluated.The dependability between carotid atherosclerosis and coronary atherosclerotic heart disease were studied.Result：There was statistical significant difference between coronary heart disease group and control carotid plaques group(P<0.05).The plaque detection rate raised significantly as coronary artery lesions involving the count increased.Also statistical difference was existed between patients between single-branch and multi-branches coronary artery disease(P<0.05).As coronary atherosclerosis progressed，carotid plaques also become more and more.And lots of plaques were soft plaques and mixed plaques.Statistical difference existed between 3D and 2D in single-branch or multi-branches coronary artery disease and superficial ulcer of soft and mixed plaques detection rate(P<0.05).There was significant positive linear correlation between carotid atherosclerosis and coronary atherosclerosis(P<0.05).The superficial ulcer of plaques detection rate of 3D diagnosis was much better than of 2D diagnosis.Conclusion：Using real-time three-dimensional ultrasonography for the evaluation of carotid atherosclerosis， the degree of coronary stenosis patients with coronary heart disease can be evalued.Major adverse cardiovascular events is effectively predicted.
