Earlobe Creases as a Marker of the Risk for Coronary Atherosclerosis Before Angiography in Elderly and Non-elderly Patients

Background The close relationship between earlobe creases (ELC) and the presence of coronary artery disease (CAD) has been reported. In addition, this study aimed to determine associations between ELC and the presence, extent, and severity of coronary atherosclerosis assessed by coronary angiography in non-elderly and elderly patients. Methods We assessed 1,086 consecutive patients with suspected CAD by coronary angiography. We defined severe CAD as Gensini scores > 20. Multiple logistic regression analysis was adjusted for age, sex, hypertension, diabetes mellitus, smoking status, lipid profiles, and body mass index (BMI) to assess the presence or absence of CAD, multivessel disease, and severe CAD in elderly (age ≥ 60 years) and non-elderly (age < 60 years) patients. Results ELC was a significantly positive determinant of CAD (odds ratio (OR) = 3.074, p < 0.001), multivessel disease (OR = 3.101, p < 0.001), and severe CAD (OR = 2.823, p < 0.001) in all patients. ELC was also a predictor of CAD, multivessel disease, and severe CAD not only in patients aged ≥ 60 years (OR = 3.095, p < 0.001; OR = 3.071, p < 0.001; OR = 2.761, p < 0.001, respectively) but also in those aged < 60 years (OR = 2.749, p = 0.035; OR = 2.634, p = 0.038; OR = 2.766, p = 0.006, respectively). Conclusions ELC was independently associated with the presence of CAD, multivessel disease, and severe CAD in both elderly and non-elderly patients who were assessed by coronary angiography.
