Diagonal earlobe crease and coronary artery disease risk – Tips from Other Journals
Controversy exists as to whether the presence of a diagonal crease on the earlobe is associated with an increased risk of coronary artery disease. To evaluate this posibility, Elliott and Karrison performed a prospective observational study.
A total of 108 hospitalized patient were included in the study. Each patient was assigned to one of four groups according to the presence or absence of coronary artery disease and the presence or absence of a diagonal crease on the earlobe. The demographic characteristics of each of the cohorts were similar. Each group consisted of 14 men and 13 women. Mean age at entry into the study was 63 years. Eight to 10 years to follow-up information was subsequently obtained regarding the dates and causes of death.
Fifty-eight of the 108 patients died during the follow-up period. The patients with earlobe creases had a significantly poorer survival rate than those without earlobe creases, whether or not they had documented coronary artery disease at enrollment in the study. Patients with earlobe creases also had a significantly higher cardiac mortality rate and a higher number of cardiac events, including nonfatal myocardial infarction and coronary artery bypass graft.
The study findings suggest that persons with a diagonal crease on the earlobe may be at increased risk of cardiac mortality. The authors recommned that these persons be cautioned to control or to eliminate risk factors, such as smoking, hypertension and obesity.
