A small diagonal fold on the earlobe, first named for a physician who described it in 1973, has drifted for decades between curiosity and clinical hope. Whether it quietly reflects the state of the heart's arteries, or merely the slow passage of years that shapes both ears and vessels alike, remains unsettled. Its story is a reminder of how readily the body offers visible hints, and how carefully we must read them before they are allowed to speak for the heart.
Earlobe Crease and Heart Risk: What Frank's Sign Can and Cannot Reveal About Heart Attack and Stroke
A small fold of skin, a decades-old question about the heart
Mark
Why does a crease in an earlobe get taken seriously at all?
Mimi
Because of the pattern in observational studies. One report in the American Journal of Medicine found it in more than 70 percent of patients undergoing angiography, and other work links it to heart attack, stroke and peripheral vascular disease.
Mark
Is there a proposed reason it would be connected?
Mimi
Yes. Some researchers think the crease reflects changes in connective tissue and tiny blood vessels, possibly a drop in elastin and collagen, which also support artery walls.
Luke
Worth saying that's a hypothesis. The source doesn't show the mechanism has been demonstrated.
Mark
And the age problem?
Mimi
Both creases and heart disease become more common as people get older. So the crease may just be tracking age.
Luke
Right, and the piece doesn't say whether studies adjusted for age. We can't tell if the link survives that. Also, that 70-plus percent figure comes from one cited report, without details on who the comparison group was.
Mark
So should someone with a crease worry?
Mimi
Clinicians say not to treat it as a diagnosis. But if you have other risk factors, or no recent heart checkup, talk to your provider about an ECG, cholesterol panel or blood pressure check.
Luke
And the sign doesn't predict anything for an individual yet. The reporting supports caution, not a prediction.

- A faint diagonal line across the earlobe has become a question mark over heart health.
- Observational studies report the crease more often in people with diagnosed heart disease, unsettling a quiet assumption about harmless skin.
- Researchers test whether shared changes in elastin and collagen link the ear to the arteries, while critics argue age explains both.
- Clinicians urge that the crease not be used as a diagnosis, and that anyone with other risk factors book simple checks like ECG, cholesterol and blood pressure tests.
A small diagonal fold on the earlobe, first named for a physician who described it in 1973, has drifted for decades between curiosity and clinical hope. Whether it quietly reflects the state of the heart's arteries, or merely the slow passage of years that shapes both ears and vessels alike, remains unsettled. Its story is a reminder of how readily the body offers visible hints, and how carefully we must read them before they are allowed to speak for the heart.
A diagonal line runs across the earlobe, angled at roughly 45 degrees, and it can appear on one ear or both. In 1973, the American physician Dr Sanders T. Frank described it, and it has carried his name ever since. For decades, people have asked whether this small fold of skin says anything about the heart.
Some scientists suspect a shared story between ear and artery. A decline in elastin and collagen, the proteins that keep blood vessels strong, might show up both in the earlobe and in the arteries that feed the heart. If so, the crease could hint at a greater risk of atherosclerosis, and with it heart attack or stroke.
Several observational studies have found the crease more often in people with heart disease, and one report noted it in more than 70 percent of patients undergoing angiography. Yet the evidence is far from settled. Because earlobe creases and heart disease both grow more common with age, the crease may simply travel alongside the illness rather than cause it.
Clinicians therefore advise against treating a lone crease as a diagnosis. It deserves attention mainly when other risk factors are present, such as high blood pressure, smoking, obesity, diabetes or family history. For anyone who notices it and has not had a recent check, the sensible step is a conversation with a healthcare provider and simple tests: an ECG, a cholesterol panel and a blood pressure reading. Those remain a far clearer guide to the heart than an earlobe.
A diagonal line runs across the earlobe, slanting at roughly 45 degrees from near the tragus down toward the lower outer edge. It can appear on one ear or both. In 1973, an American physician, Dr Sanders T. Frank, described it, and the feature has carried his name ever since: Frank's sign.
The question that has followed it for decades is whether this small fold of skin says anything about the heart. Researchers have looked for a link between the crease and coronary artery disease, the condition in which the vessels that supply the heart with blood become narrowed or blocked. The crease is not thought to come from injury, and it does not depend on how a person sleeps.
One proposed explanation concerns connective tissue and small-vessel circulation. The idea is that what happens in the earlobe may mirror what happens in the arteries. Some scientists point to a decline in elastin and collagen, the proteins that help keep blood vessels strong. If that decline is shared between ear and artery, people with the crease might be more prone to atherosclerosis, the hardening of the arteries, and so to heart attack or stroke.
Several observational studies have found the crease more often in people with diagnosed heart disease. One report in the American Journal of Medicine put the figure at more than 70 percent among patients undergoing angiography, the test used to look at the heart's arteries. Other studies have tied the sign to a higher likelihood of heart attack, stroke and peripheral vascular disease.
The evidence is not unanimous. Some research suggests the crease is mainly a marker of age. Earlobe creases become more common as people get older, and so does heart disease, which makes it hard to say whether the crease carries risk of its own or simply travels alongside it. The sign is more frequent in older people, partly because of natural changes in the skin, though it also turns up in younger people, which has fed questions about links to wider health conditions.
For that reason, cardiologists and other clinicians caution against treating a lone crease as a diagnosis. They suggest it be taken as a possible pointer, deserving more attention when other risk factors are present: high blood pressure, smoking, obesity, diabetes, or a family history of cardiovascular disease.
For someone who notices the crease and has not had their heart health checked recently, the practical advice is to raise it with a healthcare provider. The tests involved are simple and noninvasive: an ECG, a cholesterol panel, a blood pressure check. Together they give a clearer picture of cardiovascular risk than an earlobe can.
The sign remains a point of debate in medicine. It is not a definitive indicator of heart attack or stroke, but it can serve as a prompt toward further examination, particularly alongside other risk factors. Regular check-ups, healthy habits and timely care remain the more reliable protection.
