Myocarditis can go away on its own. In other cases, treatment is needed, and it can take time to resolve.
In general, treatments aim to:
- Help reduce the swelling in the heart muscle
- Ease any symptoms (for example, chest discomfort or palpitations or other related heart rhythm issues)
- Improve the heart’s pumping ability
- Treat the root cause of the myocarditis – for example, an infection or an autoimmune disease
Treatments may include:
- Heart medicines to ease the workload on the heart
- Diuretics to help the body get rid of excess fluid
- Corticosteroids to reduce inflammation in the body or other targeted medicines to suppress the immune system, such as azathioprine
- Antibiotics to fight infection caused by bacteria
- Healthy lifestyle choices, including limiting salt (sodium) intake and getting plenty of rest
- Usually avoiding strenuous physical activity for a period of time, often 3-6 months
If the inflammation of the heart muscle disrupts the way the heart beats (its rhythm), a pacemaker or implantable cardioverter defibrillator (ICD) may be needed.
Staying up-to-date with recommended vaccines is important. For example, remember to get those that protect against the flu, rubella and COVID-19.
