Based on a numerous studies conducted by scientists, a sudden appearance of hair in the ears might be associated with hearth disease.
The beginning of this research dates back to 1973 when Dr. Frank Sanders and his team published a study in the “New England Journal of Medicine”.
They discovered ear crease, which is now called “Frank’s sign” in his honor that indicates coronary artery disease. This kind of disease occurs when there is congestion of the arteries.
Another team in 1984 was guided by the same theory. Their research included 43 men and 20 women who had ear crease and hair and suffered from a heart attack.One of the scientists, Richard Wagner claimed that long-term exposure to androgen-caused clots in the arteries as a result of surplus production of red blood cells.
Later in 1989, another test was conducted that inspected the relationship between the ruts on the ear cups and coronary diseases. It included 215 patients and came to a conclusion that the disease progresses with age.
Scientists discovered a significant difference between men who have hair in their ears and those who haven’t.
After analyzing 500 autopsies they found out that most of the patients had problems with the spleen, obesity, baldness, hair in the ears, the ear creases etc.
Ear creases are associated with heart disease in both men and women, although the majority of sudden deaths were related to men. Some experts point out to testosterone supplements that men generally use as one of the main culprits for the problems with coronary disease.
