According to an investigation that was presented in the Congress of Cardiovascular Diseases organized by the Spanish Society of Cardiology (SEC) in 2014, the presence of a diagonal fold in the lobe of the ear is directly related to the condition of heart attack.

They have reached this conclusion after analyze 300 subjects to whom photographs of both ears were taken, classifying them according to the characteristics of the fold -bilaterality, inclination, length and depth-. Subsequently, the clinical history was studied to relate those who had a history of cardiovascular disease (infarction or stroke). Of the subjects studied, 31% presented the diagonal fold in the lobe.

Experts argue that the ear is, along with the nose, the only organ that grows throughout life, so when a person suffers arteriosclerotic disease also suffers small vascular lesions in various areas. In the case of these injuries on the ear, unequal growth originates encouraging the fold.


According to the experts who endorsed this study, those people who present the fold and have not been diagnosed with cardiovascular disease, it is recommended that a check be done, because it is very likely to be hypertensive, diabetic or hypercholesterolemic and, they may need treatment to control these risk factors and prevent future cardiac complications.
