- Creased earlobes and clubbed fingernails are linked to higher heart disease risk
- Other risks include halo around the iris and fatty bumps under the skin
In the West, where one in four people die of cardiovascular disease
, the importance of keeping the heart in good working order is hard to overstate. Sadly, the first sign many people have that their heart isn't in good working order is when they have a heart attack.
Although you can't see your heart beating in your chest -- not without specialist imaging technology, at least -- there are visible, external signs that can indicate if something is wrong with your heart, before you suffer from a life-changing -- or ending -- "cardiovascular event".
1. Creased earlobes
One such external indicator is diagonal creases on the earlobes -- known as Frank's sign
, named after Sanders Frank, an American doctor who first described the sign. Studies have shown that there is an association with the visible external crease on the earlobe and increased risk of atherosclerosis, a disease where plaque builds up inside your arteries.
Over 40 studies
have demonstrated an association between this feature of the ear and an increased risk of atherosclerosis. It is not clear what the cause of the association is, but some have postulated that it is to do with a shared embryological origin. Most recently, it has been seen that these creases are also implicated in cerebrovascular disease
-- disease of the blood vessels in the brain.
2. Fatty bumps
Another external indicator of heart issues is yellow, fatty bumps -- known clinically as "xanthomas" -- that can appear on the elbows, knees, buttocks or eyelids
. The bumps themselves are harmless, but they can be a sign of bigger problems.
Xanthomas are most commonly seen in people with a genetic disease called
