Heart failure is when your heart can’t pump blood around your body as it should. Symptoms can start suddenly or slowly. Heart failure isn’t curable, but some treatments might help your symptoms and improve survival.
Heart failure doesn’t mean your heart has stopped working.
It’s when your heart can’t pump blood around your body properly — usually because it’s become stiffer or weaker. Symptoms can start suddenly or increase steadily over time. When symptoms have been going on for a longer period of time, this is known as chronic heart failure.
Being over 75, having heart disease, high blood pressure, or type 1 or type 2 diabetes increases your heart failure risk.
Common symptoms of heart failure are:
Less common symptoms include feeling dizzy, having a cough, or having a fast heartbeat.
If your symptoms are serious, or they happen suddenly, it’s best to call 999, so you can get help quickly.
Several different things can cause heart failure. But it often happens because of another health condition that’s causing your heart to pump less efficiently like:
Drinking too much alcohol or binge drinking can sometimes also lead to heart failure. That’s because it raises your blood pressure. It can also lead to heart failure by weakening your heart muscles in the long term (cardiomyopathy).
If you have symptoms that keep happening or are getting worse, you should see a GP. They might do tests to help diagnose the problem, like:
Heart failure can’t usually be cured, but some treatments might help slow your symptoms down and add years to your life, like:
If you’ve had a heart attack or have heart failure, you should speak to your GP or consultant before you start a new exercise routine.
Maintaining a healthy lifestyle can reduce your heart failure risk, like:
