PURPOSE: The purpose of this study was to examine the relationship between the diagonal earlobe crease and the incidence of coronary artery disease.

PATIENTS AND METHODS: A descriptive, correlational, retrospective and concurrent approach was utilized in examining 61 patients, all with a cardiac catheterization within the last six months. All were examined for the presence of diagonal earlobe crease, presence of coronary artery disease, total blood cholesterol levels, age, sex, and past medical histories. Analyses included the Fischer's exact test, regression analysis, and multiple logistic regression analysis.

RESULTS: The mean age of all the subjects 70.3. Mean cholesterol level of all subjects= 199.68. A significant association between presence of earlobe creases and presence of coronary artery disease with P value <0.025. Gender (male) was the most predictive for the presence of CAD of the four covariates (including age, cholesterol, and ELC status), P<0.006. Earlobe status was the second most powerful predictor of CAD status, P=0.019. Neither age (P=0.40) nor cholesterol (P=0.16) were significant predictors of CAD status.
