Have you ever noticed a distinct mark or crease on your earlobe? While it might seem harmless, this subtle feature could actually be more significant than you think. Sometimes, our bodies give us small hints about bigger health issues, and a diagonal crease on the earlobe could be one of them. This mark, known as Frank’s sign, might be an indicator of poor cardiovascular health. Surprised? You’re not alone. Most people don’t associate their earlobes with heart health, but this visible sign may hold valuable clues about potential risks. Let’s dive into what this crease means, how it’s connected to heart conditions, and why you should pay attention to it.
What Is Frank’s Sign? The Story Behind the Earlobe Crease
In 1973, a researcher named Sanders T. Frank made a fascinating discovery: a diagonal crease on the earlobe could be linked to heart health. This unique feature is now referred to as Frank’s sign or Diagonal Earlobe Crease (DELC). It appears as a line or fold that stretches diagonally from the tragus (the small bump in front of the ear canal) toward the lower edge of the earlobe.
- The Science of the Crease: Frank’s sign is believed to result from the loss of elastic fibers within the skin, which causes a visible fold. While it might seem like a simple skin change, researchers have found intriguing connections between this crease and various cardiovascular conditions, including coronary artery disease (CAD) and atrial fibrillation (AF), which is characterized by an irregular heartbeat.
- Not Just an Aging Feature: While the presence of this crease becomes more common with age, it’s not just a normal sign of aging. Its appearance, particularly in younger people, has raised questions about its relationship with cardiovascular risk.
How Is the Earlobe Crease Linked to Heart Health?
The idea that a visible mark on the ear could signal issues inside the heart may seem far-fetched, but research supports a potential connection.
- Studies Linking DELC to Heart Disease: One study conducted in 2022 found that among 50 patients who suffered fatal heart attacks, 78% had the distinct diagonal earlobe crease. This prompted further exploration into whether DELC could be a visible predictor of heart disease.
- Deep Creases Indicate Higher Risk: According to a study published in 2024, individuals with deeper and longer diagonal earlobe creases were at a significantly higher risk of cardiovascular events. The study concluded that DELC is “independently associated with higher cardiovascular risk,” meaning it could be a valuable marker in assessing someone’s overall heart health.
While these findings don’t mean that everyone with an earlobe crease has heart problems, they do suggest that the crease might be more than just a superficial mark.
Atrial Fibrillation and Earlobe Crease: What’s the Connection?
The presence of a diagonal earlobe crease has also been linked to a higher risk of atrial fibrillation (AF), a condition characterized by an irregular and often rapid heart rate. AF is associated with an increased risk of stroke, heart failure, and other heart-related complications.
- Coronary Artery Disease and DELC: In patients with coronary artery disease (CAD), those who also had DELC were found to have a significantly higher risk of developing atrial fibrillation compared to those without the crease. This suggests that DELC could serve as a useful predictor of AF in people already diagnosed with CAD.
- Predicting Major Cardiac Events: Research published in the Journal of Clinical Medicine also found that the presence of DELC could predict major adverse cardiac events (MACE), such as heart attacks or sudden cardiac death, in patients with known heart disease.
Although the exact mechanism linking DELC to atrial fibrillation remains unclear, researchers speculate that the underlying changes in blood vessel health, elasticity, and circulation could contribute to both the formation of DELC and the development of AF.
Why You Shouldn’t Ignore an Earlobe Crease
While an earlobe crease might seem like a minor cosmetic issue, its potential connection to heart health warrants attention.
- Visible Indicator of Vascular Health: According to Tim Chico, Professor of Cardiovascular Medicine at the University of Sheffield, cardiovascular disease impacts not only the heart but also all blood vessels throughout the body. Therefore, visible changes, like DELC, could be a sign of vascular aging or compromised blood flow, which might reflect broader cardiovascular risks.
- Early Warning Sign: While having DELC alone isn’t a definitive diagnosis of heart disease, it could serve as an early warning sign, especially when combined with other risk factors such as high cholesterol, hypertension, or smoking. Being aware of DELC could prompt individuals to take proactive steps toward heart health, such as scheduling regular check-ups and monitoring blood pressure and cholesterol levels.
How to Lower Your Risk if You Notice Frank’s Sign
Noticing a diagonal crease on your earlobe shouldn’t cause panic, but it should encourage you to take your cardiovascular health seriously. Here are some steps to consider if you have DELC or other heart disease risk factors:
- Get a Full Heart Check-Up: If you have DELC and a family history of heart disease, it’s wise to consult a healthcare professional. They may recommend a comprehensive cardiovascular assessment, including blood tests, an EKG, and possibly a stress test, to evaluate your heart function.
- Adopt a Heart-Healthy Lifestyle: According to Professor Chico, the standard advice for reducing heart disease risk applies to those with DELC as well. Quitting smoking, maintaining a healthy weight, eating a balanced diet, and getting regular exercise can significantly lower the risk of heart-related issues.
- Monitor Blood Pressure and Cholesterol: Regularly checking blood pressure and cholesterol levels is essential for everyone, especially those with visible risk markers like DELC. Early detection and management of hypertension and high cholesterol can prevent more serious cardiovascular events down the line.
- Stay Informed: As research continues to explore the relationship between DELC and heart health, staying informed about new findings is crucial. Keeping up with medical news and research updates can help you make informed decisions about your health.
Why the Earlobe Crease’s Cause Remains a Mystery

Despite numerous studies, the exact reason why DELC develops in individuals with cardiovascular conditions is still not fully understood. While it is clear that there is a correlation, the nature of this relationship is complex.
- Speculations and Theories: Some researchers believe that changes in collagen and elastin, proteins responsible for skin elasticity, could be linked to changes in blood vessel walls as well. Since blood vessel health is critical to heart function, these changes could manifest as DELC. However, more research is needed to confirm this hypothesis.
- No Clear Genetic Link: Currently, there is no established genetic link between DELC and heart disease, which adds to the mystery. Some studies have suggested that lifestyle factors, such as smoking and obesity, could contribute to both DELC formation and cardiovascular risk, but again, further research is needed.
Conclusion: What Your Earlobe Might Be Telling You About Your Heart
While it may seem surprising, a small diagonal crease on your earlobe could be a sign of deeper cardiovascular issues. Known as Frank’s sign, this visible feature has been linked to conditions like coronary artery disease and atrial fibrillation. While it’s not a definitive diagnosis, it’s certainly a potential warning signal. If you notice DELC, consider discussing it with a healthcare professional to assess your overall heart health. Ultimately, paying attention to even the smallest changes can make a big difference in preventing serious heart conditions. Prioritize a heart-healthy lifestyle, stay informed, and remember—sometimes, your body communicates in unexpected ways.
