Heart Failure

What is heart failure?

Heart failure describes the condition where the heart muscle has become weakened and is unable to pump blood around your body as efficiently as before.
The severity and causes of heart failure mean that it’s unlikely to be completely cured but careful monitoring, medication and communication with your healthcare team can help you effectively manage the condition and live longer.
Heart failure occurs as a result of a number of conditions, the most common being:

What are the symptoms of heart failure?

Heart failure can present in many different ways but typical symptoms of heart failure are:

If you have any of these symptoms, please contact your doctor.

May’s Story

May has been living with heart failure since 2013 after suffering a series of major heart attacks. She says: “I knew I had to get to hospital. It wasn’t a case of we’ll go in the morning. I had to, because I just couldn’t breathe.”

How is heart failure diagnosed?

To diagnose heart failure, your doctor will discuss your symptoms with you and do some initial tests. These may include:

  • Checking your pulse
  • Measuring your blood pressure
  • Taking blood tests and a urine sample to test kidney, liver, and thyroid function as well as check for diabetes and anaemia
  • Take a chest x-ray to identify potential signs of heart failure and any other possible causes

If you doctor thinks that you may have heart failure, they’ll likely require further tests to confirm or exclude the diagnosis.
These include:

  • An electrocardiogram (ECG) which measures the activity of your heart and detects a previous heart attack
  • A B-type natriuretic peptides (BNP) test – a blood test that measures the levels of B-type natriuretic peptide in your blood. If you have unstable heart failure, the level of BNP will be increased.
  • An echocardiogram – an ultrasound of your heart. During this, a recorder is put on your chest and sound waves are passed through your chest to your heart. The recorder monitors the sound waves and provides information on the size of your heart, how well your heart muscle is working and how well your heart valves are working.

How is heart failure treated?

Heart failure treatment will relieve your symptoms and make your heart stronger to improve your quality of life.
There are many different treatment options available and your doctor will discuss considerations with you. These include medication, implanted devices, and surgery.
Your treatment will be decided based on the severity of your condition, your symptoms, other conditions you may have and the potential side effects that you may face.

Staying healthy following a heart failure diagnosis

When faced with a diagnosis such as heart failure, it is completely natural and understandable to feel worried and isolated. We recommend that while you come to terms with your condition and treatment plan, you have somebody with you at home for a few days or at least on the other end of the phone.
Make sure that you are taking the steps to look after yourself as much as possible. Cut down on salt, limit your alcohol intake, eat a healthy, balanced diet and control your blood pressure. Make sure that every day you’re staying active and mentally healthy – getting outside for a walk is great for your physical and mental wellbeing.
Stay in touch with your doctor and let them know if you notice any new or worsening symptoms. If you are suffering with side effects, speak to your doctor about alternative treatments or options to make you more comfortable.
If you are feeling anxious, stressed, frustrated or scared, know that you are not alone. A heart failure diagnosis can be massively disruptive and it’s understandable to struggle to come to terms with it. Try to not bottle up your feelings and speak to somebody you trust.
