Heart attacks occur when the blood supply to the heart is suddenly interrupted, and the leading cause of this is coronary heart disease (CHD). CHD is a condition in which the major blood vessels that supply the heart with blood become clogged with deposits of cholesterol. Recognising the symptoms of heart disease can help in the prevention of a heart attack developing, and one sign to look out for is blue toe syndrome.
“Without treatment, the lack of oxygen can cause the skin and underlying tissue to eventually die.”
The medical name for blue toe syndrome is cyanosis.
Blue or purple colouring may also appear in other areas of the body if a person has heart disease.
A blue or purple net-like pattern on the skin could be talking you have a blocked artery.
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 netlike pattern, it’s usually nothing to worry about.
“This netlike pattern can also be a sign of a disease called cholesterol embolisation syndrome, which occurs when small arteries become blocked.
