超声检测冠状动脉三支病变者颈动脉硬化

目的：应用超声检测冠心病冠状动脉三支病变者（三支病变）颈动脉斑块及左心功能，方法：选择经冠状动脉造影确诊为冠状动脉三支病变者52例，超声检测其左，右颈动脉及左心功能的变化。结果：斑块位于左侧颈动脉91处，右侧颈动脉78处，32．5％位于颈动脉前壁，67．5％位于后壁。心功能对照组与三支组比较P＜0．01。结论：三支病变者颈动脉班块以硬斑多见，颈动脉分叉处多分，冠脉与颈动脉病变相关密切，心功能已有损害。

Ultrasound Detection of Arteria Cervicalis Plaque and Left Heart Function in 3 - Branch- Lesion Coronary Heart Disease

Objective To detect the arteria cervicalis plaque and left heart function by ultrasound in 3-branch-lesion coronary heart disease.Methods Changes of the left heart function and bilateral arteria cervicalis were derected by ultrasound in 52 cases of socalled 3-branch-lesion coronary heart disease diagnosed by coronarography.Results There are 91 plaques in the left arteria cervicalis,and 78 Plagnes in the right arteria cervicalis 32.5% of which locates at the front wall of arteria cervicalis,and 67.5% locates at the back wall.The comparision between the changes of heart function in controlled group and the 3-branch-lesion coronary heart disease group is significanl.( P <0.01).Conclusions Hard plaque and BIF are often seen in the arteria cervicalis plaque in 3-branch-lesion coronary heart disease.There is close relation ship between coronary artery and the lesions of arteria cervicalis.The heart function has been damaged.
