摘要
目的：通过对颈动脉内中膜厚度（ IMT ）及颈动脉粥样硬化斑块的检测,探讨颈动脉粥样硬化病变的发生与冠心病的关系.方法：选择本院心血管内科住院拟诊冠心病患者120 例行颈动脉超声检查,并时记录颈动脉粥样硬化斑块的发生情况,并对发现的粥样硬化斑块根据其超声特征分为稳定型和不稳定型斑块.对各组病例的斑块发生率及不稳定型斑块发生率进行统计学分析.结果：冠心病（CAD） 组的斑块发生率明显高于非冠心病组（P〈0.05）,心肌梗死（MI）组的不稳定型斑块发生率明显高于非肌梗死组（P〈0.05）.结论：颈动脉粥样硬化斑块的发生与冠心病有明显相关性.颈动脉粥样硬化不稳定型斑块的存在与心肌梗死有相关性.
Objective： To investigate the relationship between carotid atherosclerotic on plaques on sonography and coronary artery disease （CAD）.Methods：Totally,120 patients with suspected coronary artery disease were divided into CAD group and control group according to the results of coronary angiography..The incidence rate of plaque was calculated and compared statistically.Results： The incidence rate of plaque in CAD group was signiflcandy higher than that in CON group （P〈0.05）.The incidence of unstable plaque was statistical different between the non-MI group and MI group（P〈0.05）.Conclusion ：The presence of carotid atherosclerotic plaques is related with the coronary artery disease.The unstable plaque on carotid sonography correlates with myocardial infarction.
