Ear lobe creases and heart disease.

In 50 patients with coronary heart disease (CHD) and 38 controls, comparative data on age, sex, serum cholesterol level, hypertension, obesity, diabetes, smoking habits, and ear-lobe creases were analyzed statistically. After adjustment for age differences, the factors which chiefly distinguished the two groups were the incidences of smoking, obesity, diabetes, and ear-lobe creases. Of these, the ear-lobe crease seemed to be correlated best with CHD, and may prove to be a useful diagnostic sign.
