冠状动脉狭窄与猝死关系分析

目的：分析冠状动脉狭窄与猝死关系。方法：对2005~2009年内蒙古医学院法医系接收的66例尸检病理资料进行分析。结果：猝死案例以30~50岁男性为主,有39例。无明显诱因猝死23例,有明显诱因猝死28例。冠状动脉粥样硬化Ⅰ~Ⅱ级狭窄者23例,Ⅱ~Ⅲ级狭窄者19例,Ⅲ~Ⅳ级狭窄者24例。其中左前降支狭窄最多,其次为右冠状动脉、左旋支。陈旧性心肌梗死（OMI）27例,急性心肌梗塞（AMI）14例,OMI和AMI混合存在15例。结论：猝死中冠状动脉狭窄占有很大比例,存在狭窄者大部分都有不同程度的心肌梗死。所以平素健康人群也需要预防冠状动脉粥样硬化狭窄,高危人群应做检查（如超声心动图、MDCT、冠状动脉造影）,排除冠状动脉狭窄,避免意外的发生。

Analysis of the Relationship Between Coronary Artery Stenosis and Sudden Death

Objective：To Analysis the relationship between coronary artery stenosis and sudden death.Method：Analysis of Autopsy pathological material of 66 cases from Inner Mongolia between 2005 and 2009.Result：There are 39 cases in the Sudden death cases with 30～50 year-old male primarily.There are 23 cases in no obvious incentives sudden death,28 cases in obvious incentives sudden death,and 23 cases in coronary atherosclerosis stenosis Ⅰ～Ⅱ level,19 cases in coronary atherosclerosis stenosis Ⅱ～Ⅲ level,24 cases in coronary atherosclerosis stenosis Ⅲ～Ⅳ level.Among all of those the left anterior descending anterior branch stenosis at most,then the right coronary artery and levorotatory teams.And there are 27 cases in old myocardial infarction,14 cases in acute myocardial infarction,15 cases in OMI and AMI mixed exist.Conclusion：Sudden death in coronary artery stenosis hold of a very large proportion,and most of the existing stenosis had different degrees of myocardial infarction.Therefore,healthy people also need to prevent coronary atherosclerotic stenosis,while,high-risk groups should do check（such as Echocardiography,MDCT,coronary angiography） to exclude coronary artery stenosis,and to avoid the accident happened.
