目的本文就男性冠心病患者耳折与冠状动脉影像学特点的相关性进行研究。方法选择某院2008年10月到2011年10月收治的因胸痛行冠脉造影的男性患者166例,年龄45~79岁,平均年龄56.32岁。根据造影结果分为冠心病组和非冠心病组。根据耳折程度,将患者分为两组,一组耳折组、一组非耳折组。目测法判断耳折程度。结果①冠心病组耳折积分高于非冠心病组(t=-5.51,P﹤0.01)。②耳折组的冠脉病变积分高于非耳折组(t=-4.78,P﹤0.01)。③直线回归分析,耳折与冠脉病变积分之间有直线关系,随耳折程度加重,病变积分增加。直线相关分析显示病变积分耳折积分呈正相关(r=0.37,P﹤0.01)。④多元分析:冠脉病变积分与年龄、耳折积分呈正相关(t=4.11,P﹤0.01;t=4.39,P﹤0.01)。⑤耳折与冠脉造影在诊断男性冠心病时有正向一致性(Kappa=0.51)。耳折判断男性冠心病的敏感性为83.33%,特异性78.26%,阳性似然比3.83,阴性似然比0.21。结论男性冠心病患者随耳折程度加重,冠脉病变程度加重;耳折对男性冠心病有一定的预测价值。
Aims This study was conducted to investigate the correlation between auditory stenosis and coronary angiography in male patients with coronary heart disease. Methods A total of 166 male patients undergoing coronary angiography for chest pain from October 2008 to October 2011 were enrolled in this study. They ranged in age from 45 to 79 years with a mean age of 56.32 years. According to angiography results were divided into coronary heart disease group and non-coronary heart disease group. According to the degree of ear fracture, the patients were divided into two groups, a group of ear fracture group, a group of non-ear fracture group. Visual method to determine the degree of ear damage. Results ① Coronary heart disease group ear crest score higher than non-coronary heart disease group (t = -5.51, P <0.01). ② The score of coronary lesion in the ear tip group was higher than that in the non-ear tip group (t = -4.78, P <0.01). ③ linear regression analysis, ear and coronary artery disease has a linear relationship between points, with the severity of the ear, the lesion score increased. Linear correlation analysis showed that the ear score of lesion score was positively correlated (r = 0.37, P <0.01). ④ Multivariate analysis: Coronary disease score was positively correlated with age and ear score (t = 4.11, P <0.01; t = 4.39, P <0.01). ⑤ ear and coronary angiography in the diagnosis of coronary heart disease have a positive consistency (Kappa = 0.51). Sensitivity to judgment of coronary heart disease was 83.33%, specificity was 78.26%, positive likelihood ratio was 3.83, negative likelihood ratio was 0.21. Conclusion The severity of coronary artery disease in male patients with coronary heart disease aggravates with the degree of ear fracture, and the degree of coronary artery lesion in male patients with coronary artery disease has some predictive value.
