When Can You Claim for Medical Negligence?

If you’ve had a delayed pericarditis diagnosis after being told it was heartburn, you may be eligible to claim compensation for medical negligence. Pericarditis is an inflammation of the lining surrounding the heart. When diagnosed promptly, most people recover with rest, medication, and monitoring. But when pericarditis is mistaken for something minor, such as heartburn, the delay in diagnosis may potentially cause serious harm.

If you were repeatedly told your symptoms were heartburn, only to later discover you had pericarditis, our guide below explains when a delayed diagnosis becomes medical negligence, what evidence you may need and your next step.

 

Why Pericarditis Is Often Delayed or Mistaken for Heartburn

Pericarditis can present with symptoms that overlap with gastrointestinal issues. According to the British Heart Foundation, early signs may include:

 

• Sharp or stabbing chest pain
• Typically felt onn the lefthand side of the chest
• Pain that worsens when lying down, coughing or taking a deep breath
• Pain that improves when sitting forward
• Fever
• Feeling light-headed or sick

On the other hand, heartburn typically causes burning discomfort behind the breastbone, bloating, coughing, hiccups, or a sour taste. But when chest pain is not investigated thoroughly, clinicians may assume a digestive cause and treat the patient for heartburn or acid reflux instead.

A delayed diagnosis can potentially happen when:

 

• Symptoms appear mild or intermittent
• A GP or A&E clinician attributes chest pain to heartburn without further testing
• Initial tests are not carried out
• The patient is repeatedly reassured that symptoms are “nothing serious”
• Follow‑up appointments are delayed or missed
• The patient is not referred to cardiology when symptoms persist

Unfortunately, a delay in diagnosis can allow inflammation to worsen, leading to complications such as pericardial effusion or cardiac tamponade, both of which require urgent treatment.

 

When Is a Delayed Diagnosis of Pericarditis Considered Clinical Negligence?

Not every delay in diagnosis amounts to negligence. This is because medicine is complex, and symptoms can overlap. However, in England and Wales, a delayed diagnosis may be considered clinical negligence when the care you received fell below the standard expected of a reasonably competent medical professional.

Therefore, a delayed diagnosis of pericarditis may be negligent if:

 1.Your Symptoms Were Repeatedly Dismissed as Heartburn

If you reported chest pain, difficulty breathing, fever, or pain that worsened when lying down, clinicians should consider cardiac causes. Reassuring you without proper assessment may breach the duty of care.

 

2. You Were Treated for Heartburn Without Appropriate Investigation

Chest pain should trigger tests such as:

 

• ECG
• Blood tests for inflammatory markers
• Troponin tests
• Chest X‑ray
• Echocardiogram

 

3.You Were Not Given Safety‑Net Advice

If you were told your symptoms were heartburn but not advised to return if they worsened, this may fall below acceptable standards, especially when symptoms were atypical for acid reflux.

 

4. There Was an Unreasonable Delay in Referral

If your GP or A&E clinician did not refer you for urgent cardiac assessment despite ongoing symptoms, this may also constitute negligence.

 

5. The Delay Caused You Harm

To claim compensation, it’s vital that you can show that the delay led to avoidable injury. If an earlier diagnosis would have prevented the harm, you may have grounds for a claim. This could include harm such as:

 

• Worsening inflammation
• Prolonged pain
• Hospitalisation
• Development of pericardial effusion
• Cardiac tamponade
• Long‑term cardiac complications

 

How Delayed Diagnosis Can Affect Your Health

A delay in diagnosing pericarditis can significantly worsen the condition. The longer inflammation continues untreated, the greater the risk of complications. Such consequences may impact work, daily life and even long-term health. Patients may experience:

 

• Severe chest pain
• Difficulty breathing
• Fatigue
• Recurrent episodes of pericarditis
• Need for hospital admission
• Long‑term scarring of the pericardium
• Ongoing cardiac monitoring or treatment

 

What Evidence Helps Prove a Delayed Diagnosis Claim?

Strong evidence forms the basis of any clinical negligence claim. Your solicitor will help gather all the necessary documents which typically includes:

 

1. Medical Records

These are crucial to show what symptoms you reported, what examinations were carried out, and how your condition was initially diagnosed. They also reveal whether clinicians considered cardiac causes or dismissed them prematurely.

 

2. Test Results

ECGs, blood tests, X‑rays, and echocardiograms help demonstrate how your condition progressed and whether earlier testing would have identified pericarditis sooner.

 

3. Timeline of Events

A clear timeline helps establish when and how the delay occurred. This includes:

 

• When symptoms began
• When you sought medical help
• What advice you received
• How long you were treated for heartburn
• When the correct diagnosis was finally made
• How your condition changed over time

 

4. Evidence of Harm

This may include:

 

• Hospital admission records
• Notes on complications
• Treatment plans
• Medication history
• Reports from cardiologists

 

5. Witness Statements

Your own account and statements from family members who observed your symptoms will help to show how the delay affected your day-to-day life.

 

6. Independent Medical Expert Opinion

A specialist cardiologist will review your case and provide an expert report explaining whether the delay in diagnosis fell below acceptable standards and how this caused your injury. Your solicitor will be able to arrange this consultation.

 

How to Make a Claim for Delayed Diagnosis of Pericarditis in England and Wales

If you believe your pericarditis was diagnosed late because medical professionals initially treated you for heartburn, the claims process typically involves:

 

Initial Consultation

We partner with medical negligence solicitors who offer a free consultation to assess whether your case meets the legal criteria for negligence.

Gathering Evidence

Your solicitor obtains medical records, test results, and witness statements.

Expert Medical Opinion

A cardiology expert evaluates whether the delay was negligent and whether it caused your harm.

Letter of Claim

Your solicitor sends a formal claim to the responsible NHS Trust or private healthcare provider.

Negotiation

Most claims settle without going to court. Your solicitor negotiates compensation based on your pain, suffering, financial losses, and future care needs.

Settlement or Court Proceedings

If the other party disputes liability, your solicitor may advise you to take the case to court.

 

Note: There is generally a three-year time limit from the date of the negligent treatment, or from the date you first became aware you had suffered harm caused by negligent treatment. Therefore, it’s advisable to contact an experienced medical negligence solicitor as soon as possible.

 

FAQs: Why You Should Consult a Medical Negligence Solicitor for Delayed Pericarditis Diagnosis

Why can’t I handle the claim myself?

Does consulting a solicitor improve my chances of settlement?
