earlobes are generally smooth regardless of size, color, shape and thickness. However, some people have a crease in your earlobe. This line of division of earlobe two also known as “Frank session”.
He was named after the man who first identified an important signal rather than a simple line on the skin.
In 1973, Sanford wrote a letter to Frank New England Journal of Medicine explained the possible relationship between a fold of the ear and heart disease as found by research.
ear fold and heart disease
Several other studies have been carried out later in the field, and most of them support Frank research. However, none of the studies has conclusively determined why heart disease is possibly related to the fold of the earlobe.
One theory includes the lack of blood flow to the ears leads to wrinkle formation lobe because if the blood can not get through the ears, is likely to be a blockage somewhere in the body.
Another theory says that the weakening of elastin fibers and collagen in the ears also indicates a similar weakening of the coronary arteries. The thing is the coronary arteries end in the ears which means that vascular disease in this part of the body points toward a vascular disease above the line.
According to a Japanese study, a diagonal groove (CCIP) is the result of cellular shortened telomeres, areas at the end of each DNA strand protect cells from damage. Short telomeres are often associated with metabolic syndrome. As the study, DACA is “ could be a useful surrogate marker for high-risk patients .”
A symptom observed
Even when no other symptoms, earlobe crease visible can indicate cardiovascular disease. In a study published in 2014, a man with hypertension, who had no symptoms of heart problems, except for the sample of Frank in both earlobes, went to an outpatient clinic. He was referred to evidence, which showed that his left main coronary artery was blocked 80% and 90% right was blocked. “ The patient underwent coronary bypass surgery 3 glasses and has since done well .”
Apart from the possible correlation between the signal of Frank and heart disease, the prevalence of DACA may also be cultural / regional party.
In a Japanese study, which revealed a strong correlation between the crease of the ear and heart disease, the prevalence among study subjects 1000 was lower than expected.
“ concludes that: the prevalence of CD [ear crease] in Japanese adults is very low compared with the results of previous studies in Europe and America, the prevalence of CD tends to increase with advancing age, but is not related to other risk factors for heart disease [coronary heart disease]a statistically significant association between the EC and heart disease seen from the multivariate analysis using clinical and angiographic criteria for the diagnosis of heart disease “.
Can earlobes Dar Other signs?
DACA may be an indicator of heart disease, but not in combination with other conditions. A study examining DACA as a reliable identifier of vascular disease in diabetic retinopathy and found it was not.
Therefore, a system of classification DACA was developed to show the severity of possible cardiovascular risk
- unilateral incomplete – less severe
- complete unilateral – moderate
- complete bilateral – more severe
However, it is important not to ignore this sign as early prevention is the best treatment for cardiovascular disease.
