Key result
Diagonal ear-lobe crease is linked to acute myocardial infarction as a prevalent coronary risk factor.
Why the study?
The study examined the prevalence and implications of the diagonal ear-lobe crease as a coronary risk factor alongside hypertension, diabetes mellitus, and smoking habits in patients with acute myocardial infarction.
Observational (n=531)
No
Reveals that a diagonal ear-lobe crease frequently occurs in acute myocardial infarction, suggesting its utility as an easily identifiable visual coronary risk factor.
THE diagonal ear-lobe crease described below appears more commonly in patients with coronary heart disease and should be regarded as a coronary risk factor. Although other risk factors may be present in the same patient, this crease is easily noticed and serves to identify this high-risk group.MethodDuring a three-year period from July, 1970, through June, 1973, 531 patients with acute myocardial infarction were observed in a coronary-care unit.Questionnaires were completed at the time of admission concerning the presence or absence of the diagonal ear crease, hypertension, diabetes mellitus and smoking habits. The ear crease was judged to . . .
