Correlation Of Earlobe Creases And Sublingual Vein With Coronary Heart Disease

Objective:To observe the situation of earlobe fold and sublingual vein in patients undergoing coronary angiography,and to study the diagnostic value and significance of earlobe fold and sublingual vein in coronary heart disease.Methods:From January 2019 to January 2020,223 inpatients who were admitted to xinjiang uygur autonomous region hospital of traditional Chinese medicine for coronary angiography and met the inclusion criteria were selected.On the first day of admission,the earlobe creases and sublingual vein were observed and judged.The included patients were divided into two groups according to the examination results,CHD group（n=131）and non-chd group（n=92）.The coronary heart disease group was defined as coronary angiography with stenosis greater than or equal to 30%of the left main artery,or greater than or equal to 50%of any of the other major branches(see applied internal medicine^[1]),and the patient history was collected for statistical analysis.Results:There was correlation between earlobe fold and age,hypertension,degree of coronary stenosis,and the area under ROC curve was 0.735,the sensitivity was 84.0%,and the specificity was 63.0%.There was a correlation between the degree of earlobe fold and the degree of coronary stenosis and coronary Gensini score,as the degree of coronary artery disease increases,so does the degree of earlobe fold;Sublingual vein was positively correlated with age,hypertension and stenosis degree of coronary artery disease,and the area under ROC curve was 0.684,the sensitivity was46.6%%,and the specificity was 90.2%.The degree of sublingual collaterals is related to the degree of coronary stenosis and coronary Gensini score,as the degree of coronary artery disease increases,the degree of sublingual venation will also increase;The area under ROC curve of the combined diagnosis of the earlobe crease and sublingual vein was0.804,the sensitivity and the specificity were 84.0%and 63.0%,the difference between sublingual vein+earlobe crease sign and sublingual vein was statistically significant（?2=21.380,P=0.000）.The difference between sublingual vein+the earlobe crease sign and the eearlobe crease sign was statistically significant（?2=21.140,P=0.000）.The combined diagnosis of two signs is better than single sign.Conclusion:The earlobe crease sign and sublingual vein have certain diagnostic value for the diagnosis of coronary heart disease,which may be an effective clinical indication for the prediction of coronary heart disease;There is a correlation between the degree of coronary artery disease and earlobe crease sign and sublingual vein;The combined diagnosis of two signs is better than single sign.
