For most people this may sound unbelievable, but scientists say that the latest studies have shown that there is link between ear canal hair and heart attacks.
In fact, the roots of this study go back to 1973. The New England Journal of Medicine published a study conducted by Dr. Sanders T. Frank and his team. In the article, experts explain that have identified diagonal earlobe crease which was nicknamed “Frank’s Sign” as an indicator of coronary artery disease (CAD). It is important to explain that CAD occurs as a result of plague buildup inside the human arteries and that restricts normal blood flow.
This study actually was starting point for the scientists and few years later, in 1984 group of New York doctors published an article in the New England Journal of Medicine. In that article they proposed the same theory that the ear canal hair is strongly linked to coronary artery disease. The study included 43 men and 20 women, and 90% of the participants had diagonal earlobe crease (DELC) and in same time ear canal hair experienced cardiac failure.
Scientists, including Richard F. Wagner of Boston University Medical School explain that it was long – term exposure to androgen. Androgen is the most important male hormone right after testosterone, and it led to clot formation in the arteries due to excessive production of red blood cells.
In addition to that, in 1989, the Indian Heart Journal published an abstract which actually summarizes all results of a study investigating the link between earlobe creases, ear hair and coronary artery disease. This particular study involved 215 Indian patients. The authors say: “A significant difference was also observed between men with and without CAD in the presence of ear-canal hair with age matched group”. Moreover, the experts found that ear hair prevalence advanced with age.
In June 2006, Edston published a study in the American Journal of Forensic Medical Pathology. Edston scrutinized incredible 520 autopsies in terms of BMI, spleen weight, cause of death, ear hair, earlobe crease, baldness, thickness of abdominal fat and various other characteristics.
“It was found that ELC (earlobe crease) was strongly correlated with CAD in both men and women (P < 0.0001) but with sudden cardiac death (SCD) only in men (P < 0.04)” he explained.
It is important to mention that some scientists believe that testosterone supplements are major cause for ear canal hair and heart attacks, while many other think that this is a typical characteristic of the aging process. They also consider that people die from a heart attack which is result of age or obesity, not because they simply have hair in their ear canal.
