Heart disease warning as three signs in the feet could indicate deadly illness

Three easy-to-spot symptoms on your feet could be a sign of a life-threatening condition. The signs, which can prove painful, may indicate cardiovascular disease - a leading cause of death in the UK.

Cardiovascular disease, which claims nearly 18 million lives globally each year, encompasses a range of conditions affecting the heart and circulatory system, such as heart failure, coronary heart disease, and strokes.

While some symptoms like chest pain are more well-known, others are less obvious and may appear in unlikely areas, including the feet.

According to the , there are three key warning signs of cardiovascular issues to look out for on your feet and toes.

These include painful lumps on the toes, swelling, and blue toes.

Painful lumps on the toes

Painful lumps on the toes are known as Osler nodes, which can also affect the fingers. The AAD explains: "If you have a heart infection known as infective endocarditis, these painful lumps can develop in your fingers, toes, or both places.

"The lumps can last for a few hours to several days. While the lumps go away on their own, patients need treatment for the infection. Because this infection is caused by bacteria, antibiotics can often treat it. Sometimes, surgery is also necessary."

Swelling in your feet

Swelling in your feet, medically known as oedema, could be a red flag that "your heart isn't working properly". When heart disease is present, it can cause fluid to accumulate not just in the feet but also in the ankles and legs.

The AAD has clarified: "Many diseases of the heart cause fluid to build up in your feet and lower legs. As the fluid builds up, you may see swelling, which can extend as far as the upper legs and groin."

According to the NHS, this type of swelling tends to be "better in the morning and get worse later in the day".

Blue toes

Blue toes might signal a serious health concern, indicating a blockage in a blood vessel. The AAD notes: "When you're extremely cold, your skin can turn blue (or purple).

"If an area of your skin is blue (or purple) when you're warm, that can be a sign your blood isn't getting enough oxygen. The patient in this photo has a condition known as blue toe syndrome, which happens when one or more blood vessels are blocked.

"Without treatment, the lack of oxygen can cause the skin and underlying tissue to eventually die." This condition is medically referred to as cyanosis.

The NHS lists common indicators of heart disease, including:

• Chest pain (angina)
• Shortness of breath
• Pain in your neck, shoulders, jaw or arms
• Feeling faint
• Feeling sick (nausea).

Should any symptoms arise, it's advised to consult with your GP. In cases of sudden or very severe symptoms, call 999 for an ambulance or head straight to your nearest A&E department.
