Ear lobe crease and coronary artery disease. 1,000 patients and review of the literature

Abstract

One thousand unselected patients admitted to large urban medical centers were examined for the presence of a diagonal ear lobe crease and evaluated for the presence of coronary artery disease. A high degree of correlation between the two was seen, using both clinical and angiographic criteria for the diagnosis of coronary artery disease. The association between the ear lobe crease and coronary artery disease was independent of patient age. Prospective analysis of single risk factors in 112 consecutive patients subjected to coronary cineangiography revealed that demonstrable coronary artery disease was correlated only with the ear lobe crease and with previous acute myocardial infarction (although less strongly with the latter). These conclusions are consistent with those of the world's literature, which also finds a strong correlation between coronary artery disease and the ear lobe crease, with the exception of Oriental patients, native American Indian patients, and children with Beckwith's syndrome.
