When you think about heart health, you probably think about blood pressure, cholesterol levels, exercise, and eating a balanced diet. Your skin may not be the first thing that comes to mind. However, your skin, nails, blood vessels, and heart are more connected than you might realize.
In some cases, changes in your skin can offer clues about underlying health concerns, including certain cardiovascular conditions. Yellowish deposits around the eyes, unusual bumps on the skin, changes in the nails, and certain inflammatory skin conditions are examples of things that you may want to take a closer look at.
As a medical and cosmetic dermatology practice, as well as a skin cancer center, our practitioners evaluate changes in the skin every day. While most skin concerns are not signs of heart disease, some findings can provide clues about an individual’s overall health. Recognizing these changes can help determine when a conversation with your primary care provider or another medical specialist may be beneficial.
It is important to remember that a skin change does not automatically mean you have heart disease. Many of the following symptoms have several possible causes, and some occur in people who have no underlying cardiovascular problems. However, understanding the potential connections between your skin and your heart can help you make informed decisions about your health.
Understanding the Connection Between Skin and Heart Health
Your cardiovascular system circulates blood throughout your body, delivering oxygen and nutrients to your tissues. When a condition affects circulation, cholesterol levels, blood vessels, or the body’s inflammatory response, it can sometimes produce visible changes in the skin.
For example, certain cholesterol deposits can appear as yellowish patches or bumps. Circulation problems can contribute to swelling and skin discoloration in the lower legs. Chronic inflammatory conditions, such as psoriasis, are also associated with an increased risk of cardiovascular disease.
These inferences are not a substitute for medical screening, and they cannot diagnose heart disease on their own. Instead, they are potential clues that may help healthcare providers determine whether further evaluation is appropriate.
Here are five skin and nail changes worth knowing about.
1. Skin Discoloration and Irritation Related to Circulation Problems
Changes in the skin around your ankles and lower legs can sometimes be associated with circulation problems. One example is stasis dermatitis, a type of eczema that develops when blood does not flow efficiently back toward the heart through the veins in the legs.
When blood pools in the lower legs, increased pressure in the veins can cause fluid to accumulate in surrounding tissues. Over time, this can contribute to inflammation and visible skin changes.
Symptoms of stasis dermatitis may include:
- Redness or brownish discoloration of the lower legs
- Dry, itchy, or irritated skin
- Swelling around the ankles
- Scaly patches or thickened skin
- In more advanced cases, open sores or ulcers
Although stasis dermatitis is associated with circulation problems, it is not necessarily a sign of heart disease. Chronic vein insufficiency, in which the veins have difficulty moving blood back toward the heart, is a common cause. Other medical conditions, including heart failure, can also contribute to fluid buildup and swelling.
This is just one example of how a condition affecting circulation can eventually affect the skin. A dermatologist can evaluate persistent skin discoloration, itching, or irritation in the lower legs and help determine whether it may be related to an underlying vein problem or another skin condition.
If you experience unexplained or persistent swelling in your legs, feet, or ankles, contact your primary care provider for evaluation. Seek prompt medical attention if swelling develops suddenly in one leg, particularly if it is accompanied by pain, warmth, or redness.
2. Yellowish Patches Around the Eyes
Have you noticed yellowish patches or raised areas near the inner corners of your eyelids? These may be xanthelasma, a type of cholesterol-rich deposit that develops beneath the skin.
Xanthelasma typically appears as soft, yellowish patches around the eyelids. They are generally painless and may gradually become more noticeable over time.
These deposits can sometimes be associated with elevated cholesterol or other irregularities in blood lipid levels. High cholesterol is a known risk factor for atherosclerosis, a condition where plaque builds up inside the arteries and can increase the risk of heart attack and stroke.
However, not everyone with xanthelasma has high cholesterol, and people with normal cholesterol levels can develop these deposits, too. Their presence does not automatically mean someone has heart disease.
If you notice new yellowish patches around your eyes, consider discussing them with your dermatologist or primary care provider. Depending on your medical history and other risk factors, your provider may recommend a cholesterol screening or additional evaluation.
Identifying and managing abnormal cholesterol levels can help reduce cardiovascular risk, even when there are no noticeable symptoms.
3. Sudden Clusters of Yellow or Orange Bumps
Another onset that may be associated with abnormal cholesterol or triglyceride levels is a condition called eruptive xanthomas.
Unlike xanthelasma, which typically appears around the eyelids, eruptive xanthomas often develop as multiple small, yellowish-orange bumps on areas such as the elbows, knees, buttocks, arms, or legs. They may appear relatively suddenly and sometimes resemble acne or other common skin conditions.
These bumps consist of lipid deposits in the skin and can occur when triglyceride levels in the blood become extremely elevated. Abnormal lipid levels can contribute to cardiovascular risk, depending on the underlying cause and the person’s overall health. Because eruptive xanthomas can be a visible sign of a significant metabolic problem, they warrant medical evaluation.
A dermatologist can examine the bumps and help determine whether they are consistent with xanthomas or another skin condition. If eruptive xanthomas are suspected, prompt medical evaluation and blood testing are important. Treatment focuses on addressing the underlying lipid abnormality rather than simply treating the bumps on the skin.
4. Changes in the Nails or Fingertips
Your nails can often provide clues about your overall health. Certain changes, including unusual curvature of the nails, swelling of the fingertips, or unexplained dark lines beneath the nails, may justify a visit to your dermatologist.
One example is nail clubbing, where the fingertips become enlarged and the nails curve more noticeably around the tips of the fingers. Clubbing can be associated with several medical conditions, including certain lung diseases and, in some cases, heart disease or infections affecting the heart.
Another finding is a splinter hemorrhage, which appears as a narrow reddish-brown or black line beneath a nail. These lines often result from minor trauma, even when the injury is not remembered. Occasionally, however, they may be associated with an underlying infection of the inner lining of the heart or its valves.
Neither nail clubbing nor a splinter hemorrhage is specific to heart disease. Their significance depends on the person’s medical history, other symptoms, and what is found during a skin exam.
If you notice new nail changes that cannot be explained by an injury, discuss them with your healthcare provider. This is especially important if they occur alongside fever, unusual fatigue, or other unusual symptoms. A medical evaluation can help determine whether further testing is necessary.
5. Psoriasis’ Connection to Cardiovascular Health
Psoriasis is a chronic inflammatory condition that causes skin cells to build up more quickly than usual, resulting in raised, red or discolored, scaly patches. These patches commonly develop on the scalp, elbows, knees, and other areas of the body.
Although psoriasis primarily affects the skin, its effects are not always limited to the skin’s surface. Research has found an association between psoriasis, particularly more severe disease, and an increased risk of cardiovascular conditions.
Psoriasis involves immune-system activity and inflammation. Researchers believe that chronic systemic inflammation may contribute to cardiovascular risk, alongside other factors that may be more common among people with psoriasis, such as high blood pressure, diabetes, obesity, and abnormal cholesterol levels.
Having psoriasis does not mean that you will develop heart disease. However, it is a reason to take a comprehensive approach to your health rather than focusing only on visible skin symptoms.
Managing psoriasis with an appropriate treatment plan can help control the skin condition and its associated inflammation. It is also important to maintain regular primary care visits, monitor cardiovascular risk factors, and discuss whether cholesterol, blood pressure, blood sugar, or other screening tests are appropriate for you.
If you have psoriasis, your dermatologist can help manage your skin symptoms and coordinate with your primary care provider when appropriate to support your overall health.
Do Skin Changes Mean You Have Heart Disease?
Not necessarily. Many skin changes have common, non-cardiac explanations, and even findings associated with cardiovascular conditions may occur in people who do not have heart disease.
For example, yellowish deposits around the eyes can occur in people with normal cholesterol levels. Nail changes may result from everyday injuries, and lower-leg discoloration may be related to vein problems rather than a heart condition. Psoriasis is associated with increased cardiovascular risk, but it does not mean that heart disease is inevitable.
At the same time, some cardiovascular conditions develop without visible skin changes.
The goal is not to assume the worst when you notice something different about your skin. Instead, pay attention to persistent, unexplained, or unusual changes and seek an appropriate medical evaluation when needed.
Routine preventive care remains essential. Regular checkups, recommended cholesterol screenings, blood pressure monitoring, appropriate testing for diabetes, physical activity, a balanced diet, and avoiding tobacco can all play important roles in cardiovascular health.
When Should You Seek Medical Attention?
If you notice a new or persistent skin or nail change, a dermatologist can help evaluate it and determine whether further assessment is appropriate. Depending on the results, your next step may be a dermatology appointment, a visit with your primary care provider, or additional testing.
Consider contacting a healthcare professional if you notice:
- New yellowish deposits around your eyes or unusual clusters of yellow-orange bumps
- Persistent skin discoloration, itching, or irritation around your lower legs or ankles
- New nail changes without an obvious explanation
- Psoriasis or another chronic inflammatory skin condition and questions about your cardiovascular risk
Know the signs of a medical emergency. Chest pain or pressure, severe or sudden shortness of breath, or other symptoms that may indicate a heart attack require immediate medical attention. Call 911 if you suspect a heart attack. Do not wait for a dermatology appointment or assume that a skin change explains these symptoms.
Taking Care of Your Skin and Your Overall Health
Your skin is an important part of your body’s overall health, and sometimes it can provide clues that require a more extensive look. While we as dermatologists primarily evaluate conditions affecting the skin, hair, and nails, recognizing certain findings can help identify when a patient may benefit from additional medical evaluation.
The key is to avoid jumping to conclusions. A skin change does not automatically indicate heart disease, but persistent or unusual symptoms should not be ignored.
