Cardiovascular disease remains the UK's leading cause of death, accounting for around a quarter of all fatalities annually. While many recognise typical symptoms like chest pain, experts now highlight a lesser-known warning sign that may appear on the skin.
The American Academy of Dermatology (AAD) has identified a blue or purple 'net-like' pattern on the skin, medically termed livedo reticularis, as a potential indicator of blocked arteries. This condition, often harmless when triggered by cold or certain medications, can sometimes signal cholesterol embolization syndrome, where small arteries become blocked, leading to tissue and organ damage.
According to the AAD, the pattern usually disappears when the skin warms up if caused by temperature. However, if persistent, it warrants medical attention to rule out underlying disease. The Mayo Clinic advises consulting a doctor if the pattern appears suddenly or is accompanied by other symptoms.
With nearly 18 million deaths globally each year from cardiovascular disease, early detection is crucial. UK health bodies encourage awareness of such obscure signs to improve survival rates.
