耳垂皱纹与冠心病的临床相关性研究

Clinical Study of Relationship Between Ear Lobe Crease and Coronary Artery Disease

目的 :探讨冠心病病人耳垂皱纹对冠心病的预测价值。方法 :分析 82例接受冠状动脉造影术病人耳垂皱纹的深浅及性别等与冠心病 (一支或以上冠状动脉管腔内径狭窄≥5 0 % )发生的相关性。结果 :耳垂皱纹诊断冠心病的敏感性和特异性分别为 80 .7%和68.0 % ;阳性预测值及阴性预测值分别为 85 .2 %和 60 .7%。在女性病人中其特异性高于男性 (P <0 .0 5 ) ,双侧耳垂皱纹显著的冠心病病人几乎存在前降支病变。结论 :耳垂皱纹与冠心病的发生相关 ,可考虑作为临床诊断冠心病的一个佐证。

Objective:To determine whether ear lobe crease(ELC) had an important predictive value in diagnosis of coronary artery disease(CAD), CAD was considered significant if the diameter was reduced to less than 50%. Methods:Parameters of ELC and the findings of coronary arteriographies were analyzed in 82 patients. Results:The sensitivity and specificity for CAD were 80.7%、68.0% respectively by ELC. The specificity of female was higher than that of male(P<0.05). Meanwhile, the deep groove in bilateral ear lobe strongly revealed that the left anterior descending(LAD) artery pathological changes. Conclusion:Ear lobe crease(ELC) had relation to coronary artery disease(CAD) and it could be a eidence in clinical diagnosis.
