Spotting a peculiar pattern on your skin might be more than skin-deep; it could hint at underlying cardiovascular issues. Health experts caution that a “net-like” appearance on the skin may be an indicator of tissue and organ damage due to clogged arteries.

While chest pain is a widely recognized symptom of heart problems, many other warning signs are not as apparent and can easily slip under the radar. These often manifest in unexpected places, such as the skin, which can offer subtle clues about your heart health.

According to the American Academy of Dermatology (AAD), one specific skin pattern could be a red flag for heart trouble. This pattern, characterized by a bluish or purple “net-like” appearance, may suggest an obstructed artery. The condition, known as livedo reticularis, is thought to result from spasms in blood vessels or disrupted circulation near the skin’s surface.

Despite its alarming appearance, this skin condition is usually benign and can be triggered by factors such as cold weather or certain medications. The AAD notes, “Some people notice this pattern on their skin when they are cold. Once their skin warms up, the pattern tends to fade away.”

More often than not, however, it proves harmless and is linked to various triggers, including cold temperatures or particular medicines.

The AAD explains: “Some people see this pattern on their skin when they feel chilly. When their skin warms up, this pattern disappears.

“It’s also possible to see this pattern when taking certain medications. If one of these is causing the net-like pattern, it’s usually nothing to worry about.”

However, it may indicate something far more concerning. “This netlike pattern can also be a sign of a disease called cholesterol embolisation syndrome, which occurs when small arteries become blocked,” the AAD says.

“The blockage can lead to damaged tissues and organs, so it’s important to see a doctor to find out whether you have an undiagnosed disease.”

The Mayo Clinic, in the US, adds that you should speak to your doctor if:

• The discoloured, mottled skin doesn’t go away with warming
• You have discoloured, mottled skin along with other symptoms that concern you
• Painful lumps develop in the affected skin
• Sores develop in the affected skin
• You also have a condition that affects the blood flow in your limbs
• Your skin symptoms are new and you have a connective tissue disease

The clinic also warned that a related condition, which looks similar, called livedo racemosa, may be caused by a “serious” underlying condition.

Other warning signs of heart disease include:

• Chest pain
• Pain, weakness or numb legs and/or arms
• Breathlessness
• Very fast or slow heartbeat, or palpitations
• Feeling dizzy, lightheaded or faint
• Fatigue
• Swollen limbs

If you experience any concerning symptoms, you should speak to your GP.
