Cardiac and heart disease claims

Suffering from a serious heart condition can be a worrying and stressful time for both you and your family. Discovering the medical care relating to any heart conditions you or a family member received was negligent – such as suffering a misdiagnosed heart attack – only adds to your distress.

In the UK, deaths from heart and circulatory diseases average one in every three minutes. The majority of heart disease diagnoses and cardiac operations are accurate and successful in the UK. However, there are instances where medical negligence causes or worsens the condition, which can have devastating effects. 

This can include the misdiagnosis, delayed diagnosis, inappropriate treatment and mismanagement of various heart and cardiac diseases. When this is the case, you may be able to claim for cardiac or heart failure compensation.

Common cardiac and heart disease conditions

There are many common cardiac and heart disease conditions that can be misdiagnosed. These include: 

If you’ve received negligent medical care, you may be able to bring a claim for heart failure compensation. This could be for the misdiagnosis or delayed diagnosis of your cardiac disease, or for the negligent treatment of your heart condition. 

Our specialist medical negligence teams in London and Manchester have extensive experience of bringing compensation claims against cardiac specialists. This includes surgeons and hospital doctors, as well as general practitioners, who have missed vital signs of heart disease, or have failed to refer their patients on for further cardiac investigations.

Misdiagnosed heart attack complications

If your heart condition is misdiagnosed, delayed or treated negligently, the long-term consequences for you and your family can be serious. The misinterpretation of heart disease can lead to someone experiencing pain, injury brain damage and death, in some cases.

Various factors can lead to a misdiagnosed heart attack, disease or other cardiac condition. Similar symptoms across a range of heart diseases and cardiac conditions can result in an incorrect diagnosis, followed by a prescription of the incorrect medication or a delay to the appropriate treatment. Other delays to treating heart and cardiac problems can be due to medical mistakes, incompetence and other circumstances.

How to make a cardiac and heart disease claim

To start your cardiac compensation claim, get in touch with our medical negligence team. Enjoy a free initial consultation, where one of our experts will listen to your claim, ask you relevant questions and assess if you have a strong case or not. They will then advise you on the best next steps to progress your heart claim.

To help support your claim, you will usually need to gather as much supporting evidence as possible related to your misdiagnosed heart attack, cardiac disease or other condition. This includes:

  • Medical records and documents related to your heart or cardiac diagnosis and treatment
  • Witness statements from medical professionals and/or loved ones – to assess your condition, symptoms and treatment at the time
  • Financial records to support any loss of earnings claims

What can I use cardiac and heart compensation for?

A delay to your heart surgery can result in a heart condition deteriorating to the extent that you’re unable to work and support your family. Negligence mistakes made during heart surgery can also leave you unable to continue with your career.

Any potential cardiovascular compensation claim will take into account your loss of earnings because of the negligence you have experienced. Whether you have suffered a heart attack misdiagnosis, mistreatment for high blood pressure or any other form of medical negligence related to heart and cardiac issues, compensation awarded can be used towards:

  • Loss of earnings through being unable to work during and after treatment
  • Additional medication and treatment costs
  • Long-term health effects and care costs
  • Specialist equipment – for example, if a misdiagnosed stroke leads to paralysis requiring the use of a wheelchair
  • Travel expenses to treatment and therapy appointments
  • Physical and emotional pain and suffering
  • Funeral costs

Can you claim PIP for heart failure?

There are a range of different disability benefits you can claim for heart failure dependent on the severity of your condition. Personal Independence Payment (PIP) is designed to help people with long-term ill health or disabilities with certain costs, which can include heart problems.

As a heart condition can affect your ability to work and look after yourself and your family, you may be entitled to claim some or all of the following benefits:

  • Universal credit
  • Statutory sick pay
  • Employment and support allowance
  • Healthcare travel costs
  • Free prescriptions


When you discuss any heart claims with one of our expert medical negligence solicitors, they will be able to advise you on any financial benefits you may qualify for.

Heart and cardiac compensation case studies

Heart attack misdiagnosis

Six-figure sum for a 12-year-old girl whose father died after Norfolk and Norwich University Hospital failed to realise he was having a heart attack. The 47-year-old father arrived at A&E displaying typical symptoms, but misdiagnosis meant he was not referred to the cardiology unit and tragically died two hours after walking into A&E.

£1.67 million compensation

A woman awarded £1.67 million after her heart infection was missed, which resulted in her suffering a stroke. She attended nine medical appointments in two months, where her heart infection was misdiagnosed several times and she had a stroke. Now she can no longer work and is reliant on carers.
