Quick answer
What is Myocarditis?
Myocarditis is inflammation of the heart muscle (the myocardium), most commonly caused by a viral infection, though it can also result from other infections, immune reactions, certain medicines or toxins. The inflammation can affect how well the heart pumps and its electrical activity.
- How it is treated: Treatment depends on the cause and severity.
- Self-care: Resting and avoiding strenuous exercise while the heart recovers (as advised), attending follow-up, and gradually returning to activity on medical guidance are important.
- When to seek help: See a doctor about chest discomfort, breathlessness or palpitations, especially after a viral illness.
What it is
Myocarditis is inflammation of the heart muscle (the myocardium), most commonly caused by a viral infection, though it can also result from other infections, immune reactions, certain medicines or toxins. The inflammation can affect how well the heart pumps and its electrical activity. Symptoms vary widely: some people have mild, flu-like illness with chest discomfort, while others develop chest pain, breathlessness, palpitations, tiredness or, in more severe cases, signs of heart failure or dangerous rhythm problems. It can affect people of any age, including young, previously healthy people. Because chest pain and breathlessness have serious causes, it is assessed promptly, using tests such as an ECG, blood tests, and heart scans.
How it is treated
Treatment depends on the cause and severity. Many mild cases improve with rest and supportive care as the inflammation settles, with avoidance of strenuous exercise for a period to let the heart recover. More significant myocarditis is treated in hospital, with medicines to support the heart's pumping and treat any heart failure or rhythm problems, and monitoring for complications; severe cases occasionally need intensive support. Where a specific cause is found (such as an immune condition), it is treated. Most people recover well, though some are left with lasting effects on the heart, so follow-up is arranged. Care is guided by a cardiology team, and returning to exercise is done gradually on medical advice.

Lifestyle and self-care
Resting and avoiding strenuous exercise while the heart recovers (as advised), attending follow-up, and gradually returning to activity on medical guidance are important. Reporting worsening symptoms promptly helps catch complications early.
When to get help
When to see a doctor
See a doctor about chest discomfort, breathlessness or palpitations, especially after a viral illness. Call 999 for severe chest pain, severe breathlessness, fainting, or a very fast or irregular heartbeat with feeling unwell.
