【摘要】 目的　探讨冠心病患者胸主动脉粥样硬化病变程度。方法　应用经食管超声心动图观察６８例行冠脉造影患者的胸主动脉，比较冠状动脉狭窄程度不同时的胸主动脉粥样硬化病变。结果　４２ 例阳性者胸主动脉粥样化多呈Ⅱ、Ⅲ级，２６ 例阴性者多为０ 、Ⅰ级，两组差异显著（ χ２ ＝ ３５ ．４９ ， Ｐ ＜ ０ ．００１） ，且多支冠脉病变者胸主动脉粥样化和硬化病变均较单支者严重（ Ｐ ＜ ０ ．０１ ，０ ．００１） 。结论　胸主动脉可作为反映冠状动脉粥样硬化的良好体表窗口。经食管超声心动图能同时检测胸主动脉粥样硬化的形态学和功能改变，为临床提供胸主动脉粥样硬化的全面信息。更多还原

【Abstract】 Objective To investigate the thoracic aortic athe rosclerotic lesions in coronary artery disease(CAD).Methods Sixty eight patients who had selected coronary angiography for suspected CAD were executed by transesophageal echocardiography.Results The atheromatic lesions in 42 patients with CAD were grade Ⅱ、Ⅲ,while in 26 patients without CAD were grade 0、Ⅰ mostly,the difference was significance.Furthermore,the atherosclerotic lesions of thoracic aorta was more severe in multi vessles group than that in single vessle groups.Conclusions The thoracic aortic atherosclerotic lesions could reflect the degree of coronary atherosclerotic lesions.TEE could supply the full aspectual information of thoracic atherosclerosis to meet the clinical needs.更多还原
