摘　　要：目的探讨心外膜脂肪厚度与升主动脉内径是否存在相关性,并分析心外膜脂肪厚度是否为升主动脉扩张的独立影响因素。方法通过经胸超声心动图测量90例患者的升主动脉内径和心外膜脂肪厚度,包括升主动脉内径正常组45例和升主动脉扩张组45例,运用统计学方法分析心外膜脂肪厚度升主动脉内径的相关关系。结果升主动脉扩张组心外膜脂肪厚度(5.6±0.9)mm与升主动脉内径正常组(4.5±0.6)mm比较存在显著统计学差异(P<0.01)。心外膜脂肪厚度与升主动脉内径存在强相关性(r=0.512,P<0.01)。多元线性回归分析显示EAT和年龄是升主动脉扩张的独立影响因素。结论心外膜脂肪增厚是升主动脉扩张的独立影响因素,经胸超声心动图测量心外膜脂肪厚度可以作为升主动脉扩张的新的评价指标,为临床治疗提供新的模式。Objective To investigate whether epicardial adipose tissue（EAT）thickness is correlated with ascending aortic diameter（AAD）and EAT thickness is an independent risk factor for ascending aortic dilatation.Methods There were total 90 patients,inclnding 45 of normal ascending aortic diameter（NAD）group and 45 of dilated ascending aortic（DAA）group.All patients were evaluated by transthoracic echocardiography with measurement of EAT thickness and AAD.Results EAT thickness was significantly higher in DAA group（5.6±0.9）mm compared to NAD group（4.5±0.6）mm.There was strong correlation between EAT thickness and ascending aortic diameter（r=0.512,P〈0.01）.In multiple linear regression analysis,EAT thickness and age were independently correlated to ascending aortic dilatation.Conclusion EAT thickness is an independent risk factor for ascending aortic dilatation.
