[The diagonal ear lobe crease for evaluating coronary risk]

Abstract

Though the predictive value of a diagonal earlobe crease (ELC) concerning coronary heart disease (CHD) is assessed controversially and seems to be influenced by age and ethnic origin, the ELC is mainly regarded as a reliable and valid sign of CHD. 670 patients, the greatest collective so far undergoing coronary angiography, were investigated prospectively with respect to the correlation between ELC and a hemodynamically relevant CHD (coronary diameter stenosis > 70%). In presence of ELC, CHD was observed in 55.0%, in its absence in 55.9% (One-vessel-disease (1-VD) 25.8% vs 26.7%, 2-VD 14.5% vs 14.4%, > 2-VD 14.8% vs 14.8%; n.s.). ELC itself was dependent on age (p < 0.000009), overweight (body mass index (BMI) > 25 kg/m2, p < 0.034) and hyperuricemia (> 7.0 mg%; p < 0.05), but not influenced by sex and other coronary risk factors such as smoking, diabetes, hypercholesterinemia and hyperlipoidemia, physical in-activity and family history of CHD. Actual just as former smoking and male sex are associated positively to CHD, whereas diabetes, hypercholesterinemia and hyperlipoidemia seem to predict a two-or multivessel disease: this emphasizes the validity of our data.

Conclusion: The ear-lobe crease is associated with age and overweight, but does not predict a hemodynamically relevant coronary heart disease.
