Heart disease is one of the leading causes of death worldwide, yet some cardiovascular problems can develop for years without obvious symptoms. That’s why recognizing potential warning signs and keeping up with routine health checks are so important.
Sometimes, your body offers clues that something deserves attention. You might notice a yellow patch near your eyelid, unexplained changes in your legs, or swelling around your ankles. Certain findings have been associated with cardiovascular risk factors, although they can also have entirely different causes.
Here’s the important thing to remember: a physical sign does not automatically mean you have heart disease, and having no visible warning signs does not guarantee that your heart is healthy.
In this article, we’ll explore seven signs worth knowing, explain what they may indicate, and discuss when to seek medical advice. We’ll also cover the symptoms that should never be ignored.
1. Frank’s Sign: A Diagonal Crease on the Earlobe

Have you ever noticed a diagonal crease running across an earlobe?
Known as Frank’s sign, this fold typically extends diagonally from near the ear opening toward the lower edge of the earlobe.
Researchers have investigated a possible association between this crease and coronary artery disease, a condition in which plaque builds up inside the arteries supplying blood to the heart.
Some studies have reported an association between earlobe creases and cardiovascular disease. However, the evidence is not conclusive enough for the crease to serve as a reliable diagnostic test.
Age, genetics, and other factors can influence the appearance of earlobes, too.
What Should You Do?
If you notice a diagonal earlobe crease, there’s no need to panic.
Instead, pay attention to established cardiovascular risk factors, including:
- High blood pressure
- Elevated LDL cholesterol
- Diabetes
- Smoking
- Physical inactivity
- A family history of early heart disease
A healthcare professional can help determine whether you need blood pressure monitoring, cholesterol testing, or additional assessment based on your overall health.
The takeaway: An earlobe crease is not proof of blocked arteries. Your overall risk factors and medical history are much more useful when assessing your heart health.
2. Unexplained Hair Loss on Your Legs
Have you noticed that the hair on your lower legs seems thinner than it used to be?
Changes in leg hair growth can happen with age, but unexplained thinning may sometimes accompany peripheral artery disease (PAD).
PAD develops when arteries supplying the legs become narrowed, commonly because of atherosclerosis—the buildup of plaque inside artery walls. Reduced blood flow can affect the tissues in your feet and legs, sometimes contributing to changes in the skin and hair.
However, hair loss alone cannot diagnose poor circulation. Genetics, hormonal changes, aging, and skin conditions may also play a role.
