Sometimes researchers find interesting ancillary information when trying to find answers to the most puzzling health problems. In the past few years, many of these unusual findings have been linked to the risk of heart disease in individuals.

Earlobe crease

from

This sounds incredible and interesting, but more than twenty scientific studies conducted over the past few decades have examined the relationship between earlobe creases and increased risk of heart disease. Perhaps the most famous of these studies was published in 1991. Researchers at the University of Chicago tracked more than 100 subjects for 10 years and found that individuals with diagonal creases on the earlobe had significantly more heart disease or death. Heart disease associated with people without such creases. Researchers in Chicago are not alone.

Swedish researchers conducted more than 500 autopsy tests on patients with cardiac arrest or heart disease and found that earlobe creases were a "positive predictor" for more than 68% of subjects they examined. More than 80% of subjects under the age of 40 who died of coronary artery disease had earlobe folds. A Turkish study has shown that earlobe wrinkles are a more serious risk factor for heart disease than family history, diabetes and even smoking. At the Montreal Heart Institute, researchers reviewed nearly 350 patients admitted to the hospital. Among them, 91% of patients with lobe folds had heart disease, while only 61% of patients without wrinkles had heart disease. Irish scientists studied nearly 250 patients and found that more than 71% of participants' earlobe creases were signs of heart disease.

All of these studies seem to support what statisticians call low sensitivity – high specificity. This means that people without earlobe creases may not be immune from heart disease, but people with earlobe creases are more likely to develop cardiovascular disease at some point in their lives. Although this evidence appears to provide strong evidence for the relationship between earlobe creases and cardiovascular disease, it must be noted that many similar studies have not found such a link. There is no medical consensus on whether earlobe creases are important indicators of heart disease or the susceptibility of individuals to them. Most experts believe that wrinkles increase with age and the risk of cardiovascular disease increases.

However, earlobe folds are certainly not the only unusual risk factor for heart disease.

Leg length

from

In 2004, British researchers at the University of Bristol announced that they had found evidence to support the relationship between female leg length and risk of heart disease. Among the 4,000 participants, the shortest leg had the highest risk of heart disease. For every four centimetres of the specified baseline leg length, the risk is reduced by 16%. Even after leading to traditional heart disease such as higher cholesterol, weight, age, smoking and lung dysfunction, leg length is still a strong indicator of risk.

Ring finger length

from

Researchers at the University of Liverpool in the United Kingdom have found that men with short ring finger have lower testosterone levels, which increases their risk of early heart attack. Liverpool's study measured the participant's index and ring finger and then separated the length. In subjects with measurements greater than 1.0, testosterone levels were found to be significantly lower than subjects whose measurements decreased with smaller measurements. Low testosterone levels are associated with earlier heart attacks.

Male pattern baldness

from

In a study of more than 22,000 male doctors, the researchers found that patients with alopecia are more likely to have a heart attack 10% higher than non-bald patients, and more patients with alopecia or crown baldness. The risk of heart disease is 23% to 40%. A study conducted by researchers at the University of Arizona in 2007 confirmed that baldness did increase the risk of heart disease, but concluded that hair loss itself is not a reliable indicator of risk.

Bad breath

from

Bad breath is only one of the side effects caused by advanced gum disease, and studies have shown that antibodies produced by individuals with this disease increase the risk of heart disease by 100%. In fact, one study even reported that treating gum disease can reverse the thickening of the carotid artery.

Clean skin

from

A study in the United Kingdom is generally considered to be a positive feature, and the discovery of transparent skin may be a life-threatening disease. Among the 11,000 men who participated in the study, adolescent acne patients were 30% less likely to die of cardiovascular disease or heart disease in middle age and later.

Faded mucus

from

A recent study published in the journal Biochemistry showed a link between cardiovascular disease and green mucus. Discoloration is caused by an enzyme called myeloperoxidase in the body that fights bacteria by producing acids that can damage tissues and cause thickening of asthma, arthritis and arterial walls.

earwax

from

There are two different types of earwax: dry and moist. Individuals produce only one or the other within their sphere of life, and the type of earwax appears to be a hereditary trait. A Japanese study in 1966 found that people who produce dry earwax have an increased risk of arterial thickening than those who produce wet earwax. Since then no other studies have confirmed these findings – later peer review actually concluded that the results should be suspected. However, when people consider all other strange indicators of heart disease, the earwax produced by one person is certainly no more strange than any other potential risk factor.

Cardiovascular disease is a serious, life-threatening disease that must not be taken lightly. However, these unusual risk factors will certainly increase the frivolity of the dialogue.
