What will happen to me?

Everyone is different, and it's difficult to say what will happen to you. Your symptoms may reduce on their own, they may stay the same, or they may gradually get worse.

If you have peripheral arterial disease you're more likely to have a heart attack or a
 
 
 
 
 
stroke
You have a stroke when the blood supply to a part of your brain is cut off. This damages your brain and can cause symptoms like weakness or numbness on one side of your body. You may also find it hard to speak if you've had a stroke.

  • Over a period of five years, 1 in 5 people with pain in their calf when they exercise have a heart attack or a stroke.
  • People with peripheral arterial disease are two to three times more likely to die than people who don't have this condition.
  • About 3 in 10 people with peripheral arterial disease die within five years of having the disease diagnosed. About 7 in 10 die after 15 years. Mostly, people die because of
     
     
     
     
     
    heart disease
    You get heart disease when your heart isn't able to pump blood as well as it should. This can happen for a variety of reasons.
