Heart attacks are serious medical emergencies that require immediate attention from a doctor. You could be at risk of a deadly heart attack – or myocardial infarction – if you suddenly notice this unusual mark when you take your socks off it could signal the dangerous condition.
What is peripheral edema?
Edema happens when your small blood vessels leak fluid into nearby tissues, explained WebMed.
The health site continued: “That extra fluid builds up which makes the tissue swell.
“It can happen almost anywhere in the body.
Peripheral edema usually affects the legs, feet and ankles, but it can also happen in the arms.
“It could be a sign of problems with your circulatory system, lymph nodes or kidneys.”
When the heart is weak or damaged it can’t pump blood efficiently.
Blood and fluid then back up into the legs and sometimes the lungs.
Most often, peripheral edema develops when excess fluid in your body is pulled into your legs by gravity. The edema is usually mild, temporary, and harmless.
However, peripheral edema can be a symptom of an underlying medical condition. If so, the edema is more severe and persistent, and there are usually other symptoms.
How to respond to a heart attack
According to the BHF, the first thing you must do is dial 999 immediately for an ambulance.
“Don’t worry if you’re not completely sure whether your symptoms are a heart attack, it’s really important that you seek medical attention regardless as quickly as possible,” explains the health body.
