Warning signs can appear on your skin and nails, which is why your dermatologist may be the first doctor to notice that you have heart disease. If you know what to look for, you can also find warning signs of heart disease on your skin and nails. The following pictures show you what to look for.
Swelling in your feet and lower legs
What it may be telling you: Your heart isn’t working properly.
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.
Medical name: Edema (medical term for swelling)
Blue or purple color on your skin
What it may be telling you: You have a blockage in a blood vessel.
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’s 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.
Medical name: Cyanosis (refers to the bluish color on the skin)
