Your body constantly alerts you to the possibility of a heart attack. Doctors say that most of us don't listen to it, though. In the days or hours preceding a cardiac event, some people have early symptoms of the illness, which may be far less evident than you may think.
 
Early detection of heart attack symptoms can save your life or the life of a loved one.
 
Your dermatologist may be the first to identify heart problems in you since warning signals might show up on your skin and nails. Your skin and nails can also be indicators of disease if you know what to look for.

Blue or Purple Color
 
The intense cold causes your skin to turn blue or purple. Blue toe syndrome, which occurs when one or more blood vessels are stopped, is caused by inadequate oxygen intake, according to doctors. Without treatment, the illness, often referred to as cyanosis, results in the death of the skin and underlying tissue.

Blue or purple net-like pattern

There have been a few occasions when you felt cold and noticed a net-like pattern on your skin that was either blue or purple.  This pattern goes away when the skin gets warmer.  When taking specific drugs, this pattern may also be observed.  Usually, there is no reason to be concerned if one of these is the source of the netlike pattern.
 
A condition called cholesterol embolization syndrome, which happens when small arteries become clogged, may also be indicated by this net-like pattern. It is crucial to consult a physician to determine whether you have an undiscovered illness because the obstruction may result in harm to your tissues and organs.

Yellow-orange, waxy growths on skin

You can have cholesterol deposits beneath your skin if you see yellowish-orange growths on it. These deposits can show up in a variety of places, such as the backs of your lower thighs, the corners of your eyes, or the lines on your palms, despite the fact that they are painless.
 
Consult your physician if you observe these growths on any part of your skin. You could require a medical test, such as a cholesterol test.  Treatment is necessary for unhealthy cholesterol levels in order to avoid potentially fatal heart disease.  Controlling your cholesterol levels may also aid in the removal of skin growths.

Finger clubbing

Your fingers may be inflamed, and your nails may start to bend from one end, which could indicate lung issues, heart trouble, or an infection. For many, these symptoms are innocuous.
 
However, it is best to check out if you might have a medical condition, such as lung disease or a heart problem, if your fingers and nails look like this.

Waxy bumps on your skin

Protein deposits in your heart or another organ may be indicated by waxy pimples on your skin. Anywhere on the skin, the waxy lumps are a sign of an organ, such your heart, having an abnormal protein buildup. It is difficult for the heart to function correctly if protein accumulates in it.
