To the Editor: The ear-lobe crease has been demonstrated to be significantly associated with coronary-artery disease in specific populations.1 Patterns of hair growth have previously been suspected as possible risk factors for coronary-artery disease.2,3 We investigated both the ear-lobe crease and ear-canal hair — the presence of one or more terminal hairs growing on the tragus or antitragus or from the external acoustic meatus (Fig. 1) — in 43 men and 20 women (36 to 76 years of age; mean, 56.3) who underwent coronary cineangiography. Coronary-artery disease was defined as a 50 percent or greater luminal narrowing of one.
