According to coronary angiography results, they were categorized into the CHD (n=457) and non-CHD groups (n=249).Results: The trial demonstrated a significant positive relationship between DELC and CHD. Independent risk factors were sex, age, hypertension, diabetes mellitus, LP (a), Cys C, and DELC, whilst HDL-C was a protective factor, for CHD. Patients with-DELC were older than those in the without-DELC arm (P< 0.001) and had a higher proportion of males than females (61.6% vs 50.0%, P=0.026). After multifactorial correction, independent risk factors for CHD included DELC (OR=1.660, 95% CI:1.153 to 2.388, P=0.006), age (OR=1.024, 95% CI:1.002 to 1.045, P=0.030), gender (OR=1.702, 95% CI:1.141 to 2.539, P=0.009), hypertension (OR=1.744, 95% CI:1.226 to 2.482, P=0.002), diabetes mellitus (OR=2.113, 95% CI:1.404 to 3.179, P< 0.001), LP(a) (OR=1.010, 95% CI:1.003 to 1.017, P=0.005), Cys C (OR=3.549, 95% CI:1.605 to 7.846, P=0.002). The Hosmer and Lemeshow (H-L) test (P=0.818) suggests a high goodness of fit, and the area under the ROC curve was calculated to be 0.721 (95% CI:0.682 to 0.760, P< 0.001), which demonstrates that the model has a superior diagnostic value for CHD.Conclusion: DELC is an independent risk factor for CHD after adjusting for sex, age, hypertension, diabetes mellitus, smoking index, LP (a), Cys C, and HDL-C. Our model can be used clinically for assessing the risk of CHD.Keywords: coronary heart disease, diagonal earlobe crease, coronary angiography, model
