Have you ever noticed a diagonal crease running across your earlobe? It might look like an ordinary wrinkle, especially as you get older. However, researchers have been studying a possible connection between this small physical feature and cardiovascular health for decades.
Known as Frank's sign, a diagonal earlobe crease has been associated in some studies with coronary artery disease, a condition in which the blood vessels supplying the heart become narrowed or blocked.
But does having this crease mean you have a heart problem? Can a simple look in the mirror reveal your risk of a heart attack?
The answer is more complicated than many headlines suggest.
Although some research has found an association between diagonal earlobe creases and cardiovascular disease, the evidence is not strong enough to use the crease alone to diagnose heart problems. Age-related skin changes and other factors may also contribute to its appearance.
Understanding what scientists have discovered—and what remains uncertain—can help you make informed decisions about your heart health without unnecessary worry.
1. What Is Frank's Sign?

Frank's sign is the name given to a diagonal fold or wrinkle that extends across the earlobe, often running at an angle from near the ear canal toward the lower edge of the ear.
It was described by physician Sanders T. Frank in 1973 after he observed the feature in patients with coronary artery disease.
The crease may appear on one earlobe or both. Some are shallow and subtle, while others are deeper and more noticeable.
Unlike a temporary mark caused by sleeping on your side, a typical diagonal earlobe crease is a persistent fold in the skin.
Researchers have investigated whether its presence might provide a visible clue to underlying cardiovascular changes.
However, Frank's sign is not an officially established diagnostic test for heart disease. A person can have an earlobe crease without coronary artery disease, and someone with significant heart disease may have no crease at all.
2. Why Is an Earlobe Crease Linked to Heart Health?
The proposed connection involves changes that may occur in the body's tissues as people age and develop cardiovascular risk factors.
Coronary artery disease commonly develops when fatty deposits, cholesterol, and other substances accumulate in artery walls. This process, known as atherosclerosis, can restrict blood flow to the heart.
The earlobe crease itself does not cause this process. Instead, researchers have explored whether it could sometimes reflect broader changes in the body's connective tissues, small blood vessels, or aging processes.
Several explanations have been proposed:
- Aging and skin changes: The skin loses elasticity as people get older, potentially contributing to persistent folds.
- Changes in connective tissue: Alterations in collagen and elastin have been proposed as possible contributors to the crease.
- Shared cardiovascular risk factors: Some people with an earlobe crease may also have factors associated with cardiovascular disease, such as smoking, high blood pressure, or diabetes.
These are possible explanations rather than a fully established mechanism.
Scientists have not demonstrated that the crease itself causes cardiovascular disease or that every crease reflects damage to the arteries.
3. What Does Scientific Research Actually Say?
Studies investigating Frank's sign have produced mixed results, although several have reported an association with coronary artery disease.
A systematic review published in 2021 examined 13 studies involving 3,951 patients. The researchers found considerable variation in the crease's ability to identify coronary artery disease, with sensitivity ranging from 26% to 90% and specificity ranging from 32% to 96%.
The review concluded that the crease's diagnostic accuracy was insufficient to establish or rule out coronary artery disease reliably. Its presence or absence should not determine medical management on its own. Read the systematic review in the Journal of Clinical Medicine.
Other research has reported more encouraging associations.
For example, an observational study published in The American Journal of Medicine in 2024 examined 1,050 adults in Spain. It found that participants with diagonal earlobe creases tended to have higher estimated cardiovascular risk scores. The association was more pronounced when creases were present on both earlobes or were deeper and longer. Read the study summary.
A systematic review and meta-analysis published in 2025 also reported an association between earlobe creases and coronary artery disease. However, an association does not establish that the crease is a reliable screening test for individuals in the general population. Read the review in the Journal of Laryngology & Otology.
What should you take away from these findings?
The evidence suggests that an earlobe crease may be associated with cardiovascular risk in some populations, but its usefulness as an individual warning sign remains limited.
It should not replace established assessments such as blood pressure measurement, cholesterol testing, diabetes screening, medical history, and evaluation of symptoms.
4. Does Having a Crease Mean You Have Heart Disease?
No. An earlobe crease does not automatically mean you have a heart condition.
Many people develop wrinkles and folds as part of normal aging. Others may have a diagonal crease without having clinically significant coronary artery disease.
Likewise, the absence of a crease does not guarantee that your heart and arteries are healthy.
This is an important distinction because cardiovascular disease can develop silently for years. High blood pressure and elevated cholesterol, for example, often produce no obvious symptoms.
Rather than treating an earlobe crease as a diagnosis, consider it—at most—a reason to reflect on your overall health and whether you are keeping up with recommended preventive care.
If you have concerns about your cardiovascular risk, a healthcare professional can assess your individual circumstances and recommend appropriate tests.
5. What Other Signs of Heart Disease Should You Know?
An earlobe crease is not a substitute for recognizing symptoms that may indicate a genuine cardiovascular problem.
Coronary artery disease can cause symptoms when the heart muscle does not receive enough oxygen-rich blood. Some people experience symptoms during physical activity, while others develop symptoms at rest.
Important warning signs include:
Chest discomfort
Pressure, squeezing, tightness, heaviness, or pain in the chest can be a sign of a heart problem.
The sensation may last several minutes, disappear and return, or occur during physical exertion.
Shortness of breath
Unusual breathlessness during everyday activities or at rest can sometimes indicate a cardiovascular problem, particularly when it occurs with chest discomfort or fatigue.
Pain or discomfort in other areas
Heart-related discomfort may spread to one or both arms, the shoulders, the back, the neck, the jaw, or the upper abdomen.
Unexplained fatigue
Some people experience unusual tiredness or reduced exercise tolerance, although fatigue has many possible causes and is not specific to heart disease.
Dizziness or fainting
These symptoms can have several explanations, but sudden fainting or dizziness accompanied by chest pain, breathing difficulties, or palpitations requires urgent assessment.
Seek emergency medical care if you experience possible heart attack symptoms, including chest pressure, shortness of breath, cold sweats, nausea, or discomfort spreading to the arm, back, neck, or jaw. Do not wait for an earlobe crease or any other visible sign to confirm that something is wrong.
Heart attacks do not always present with dramatic chest pain, and symptoms can vary between individuals.
6. What Should You Do If You Notice a Diagonal Earlobe Crease?
If you notice a crease while looking in the mirror, there is generally no need to panic.
The crease alone does not establish a diagnosis, and it does not automatically mean that you need specialized heart imaging or other invasive testing.
Instead, consider your overall cardiovascular health.
Check your blood pressure
High blood pressure is a major risk factor for heart disease and often has no noticeable symptoms.
Regular measurement can help identify elevated readings that need further evaluation.
Know your cholesterol levels
High levels of certain blood lipids, particularly LDL cholesterol, can contribute to atherosclerosis.
A healthcare professional can advise you on cholesterol testing and how often it should be repeated.
Consider diabetes screening when appropriate
Diabetes increases the risk of cardiovascular disease. Your age, medical history, symptoms, and other risk factors help determine whether testing is appropriate.
Review your family history
A history of early heart disease in close relatives may increase your cardiovascular risk. Share relevant family history with your healthcare professional.
Discuss your concerns with a clinician
If you have several cardiovascular risk factors or are worried about your heart health, arrange a routine appointment.
Your clinician can determine whether a formal cardiovascular risk assessment or additional testing is warranted. An earlobe crease by itself does not determine which tests you need.
7. How Can You Reduce Your Risk of Heart Disease?
Whether or not you have an earlobe crease, the most effective approach is to focus on cardiovascular risk factors that can be measured and managed.
Eat a balanced diet
Emphasize vegetables, fruit, whole grains, legumes, nuts, and other nutrient-rich foods. Choose healthier sources of fat and limit excessive sodium, added sugars, and heavily processed foods.
Stay physically active
Regular physical activity supports cardiovascular health, blood pressure management, and overall fitness.
Many adults can work toward at least 150 minutes of moderate-intensity aerobic activity per week, adjusted to their abilities and medical circumstances.
Avoid smoking
Smoking damages blood vessels and increases the risk of heart attack and stroke. Quitting can improve cardiovascular health, and healthcare professionals can offer support and treatment options.
Maintain a healthy weight when appropriate
Excess body weight can contribute to high blood pressure, diabetes, and other cardiovascular risk factors. Focus on sustainable habits rather than extreme diets.
Manage blood pressure, cholesterol, and blood sugar
Follow your healthcare professional's recommendations for screening, lifestyle changes, and medications when needed.
Prioritize sleep and stress management
Adequate sleep and healthy ways of managing stress support overall well-being. Persistent sleep problems or significant emotional distress may warrant professional advice.
These measures have a stronger foundation in cardiovascular prevention than relying on a physical feature such as an earlobe crease.
8. Can an Earlobe Crease Be Prevented or Removed?
There is no established method for preventing Frank's sign specifically, and removing the crease would not reduce cardiovascular risk.
The appearance of the earlobe may be influenced by age, genetics, skin structure, and other factors.
Moisturizers and gentle skin care can help maintain the skin's condition, but they have not been shown to prevent or reverse any proposed association between an earlobe crease and cardiovascular disease.
Cosmetic treatments may alter the appearance of a crease, but they do not treat the underlying processes responsible for coronary artery disease.
If your concern is heart health, focus on risk assessment and preventive care rather than trying to remove the visible fold.
Frequently Asked Questions
What does a diagonal crease in the earlobe mean?
A diagonal earlobe crease is a persistent fold in the skin known as Frank's sign. Research has linked it to cardiovascular disease in some populations, but it is not a reliable stand-alone diagnostic test.
Does Frank's sign mean a heart attack is coming?
No. The crease cannot predict when a heart attack will occur, and having one does not mean that a heart attack is inevitable.
Is a crease in both earlobes more concerning?
Some observational studies have reported stronger associations between cardiovascular risk and creases affecting both earlobes. However, this finding is not sufficient to diagnose heart disease or determine an individual's risk without a broader clinical assessment.
Can young people have an earlobe crease?
Yes. A crease can occur in younger people as well as older adults. Its presence does not establish cardiovascular disease, and its absence does not rule it out.
Should I see a cardiologist if I have Frank's sign?
Not necessarily. An earlobe crease alone does not automatically require a cardiology referral. Your symptoms, age, medical history, blood pressure, cholesterol, and other risk factors help determine whether further assessment is needed.
Can someone have heart disease without an earlobe crease?
Yes. Many people with cardiovascular disease do not have an earlobe crease. The feature is not sensitive or specific enough to exclude or confirm disease.
What is the most reliable way to check your heart health?
A healthcare professional can assess your cardiovascular risk using your medical and family history, blood pressure, cholesterol levels, diabetes status, smoking history, and other relevant factors. Additional tests may be recommended depending on your symptoms and risk profile.
Final Thoughts
That small diagonal crease in your earlobe may be more than a cosmetic feature, but its significance should not be exaggerated.
Research has identified associations between Frank's sign and cardiovascular risk, yet the available evidence does not support using the crease alone to diagnose heart disease or predict a heart attack.
If you notice the crease, use it as an opportunity to consider your overall health rather than a reason to assume something is wrong.
Know your blood pressure and cholesterol levels, follow appropriate screening recommendations, maintain healthy habits, and discuss your personal risk factors with a healthcare professional.
Most importantly, never ignore symptoms such as chest discomfort, unusual shortness of breath, or pain spreading to the arm or jaw simply because you do or do not have a visible earlobe crease.
When it comes to heart health, measurable risk factors, appropriate medical assessment, and early attention to symptoms matter far more than a single wrinkle.
