颈动脉粥样硬化与缺血性心肌病的相关性研究

目的:探讨颈动脉超声显像对缺血性心肌病(ICM)预测价值。方法:应用B型超声血管探头检查经选择性冠状动脉造影的89例心脏扩大或心功能减低患者双侧颈动脉内膜—中层厚度(IMT),比较缺血性心肌病组和非缺血性心肌病(non-ICM)组IMT差异。结果:89例患者中,53例(61.6%)为ICM,36例(41.9%)为non-ICM。ICM患者中,IMT>1.0 mm者50例(94.3%);non-ICM患者中,IMT>1.0 mm者6例(16.7%)。ICM组与non-ICM组患者的颈动脉IMT比较差异有统计学意义(P<0.05)。比较颈动脉粥样硬化(内膜—中层厚度IMT>1.0 mm)判断缺血性心肌病的敏感性和特异性分别为94.3%、83.3%。结论:颈动脉超声是一种简单、可行的鉴别缺血性和非缺血性心肌病的方法。颈动脉粥样硬化(CAS)对ICM是一项有价值的超声预测指标。

Correlation of carotid atherosclerosis and ischemic cardiomyopathys

Objective： To explore predictive value of carotid ultrosound imaging in diagnosis of ischemic cardiomyopathy（ICM）.Methods： A total of 89 patients with cardiac dilatation or cardiac insufficiency were examined by caritid ultrosonography and coronary angiography.Bilateral carotidartery intima-media thickness（IMT） was compared between ICM group and non-ICM group.Results： There were 50 patients with carotid IMT 1.0 mm in ICM group（94.3%,50/53）,and 6 patients in non-ICM（16.7%,6/36）.There was significant difference between the ICM group and the non-ICM group.The sensitivity for the diagnosis of ICM was 94.3% and the specificity was 83.3%.Conclusiona： Caritid ultrosonography is a useful means to identify ICM and non-ICM.Carotid atherosclerosis is a valuable echocardiography marker for diagnosis of ICM.
