Understanding Myocarditis
Myocarditis is an inflammation of the heart muscle. It can range from mild and temporary to severe, but most people recover fully with the right care. Treatment focuses on resting the heart, managing inflammation, and supporting heart function.
What Is Myocarditis?
Myocarditis happens when the heart muscle becomes inflamed, often after an infection such as a cold or a flu‑like illness. The inflammation may weaken the heart’s ability to pump blood, leading to symptoms like:
- Chest pain or pressure
- Shortness of breath
- Heart palpitations
- Extreme tiredness or fainting
Common Causes
- Viral infections (most common)
- Certain bacteria, parasites, or toxins
- Reactions to medications or drugs
- Autoimmune diseases that attack the heart
Diagnosis
Doctors diagnose myocarditis using:
- Electrocardiogram (ECG)
- Blood tests for heart damage
- Echocardiogram (ultrasound of the heart)
- Cardiac MRI to confirm inflammation
- Occasionally, a small heart tissue biopsy
Treatment and Self‑Care
- Rest: Avoid strenuous physical activity for several months.
- Monitoring: Hospital observation may be needed early on to track heart rhythm and blood pressure.
- Pain relief: Simple painkillers may help, but anti‑inflammatory drugs are used cautiously.
Medications
- Heart support: ACE inhibitors, beta‑blockers, and diuretics can reduce strain on the heart.
- Arrhythmia control: Medicines or temporary devices may help regulate heartbeat.
- Severe cases: Mechanical support devices like ECMO or temporary heart pumps may be used until recovery.
Treating the Cause
- Antibiotics for bacterial infections.
- Immune‑suppressing medication for autoimmune myocarditis (after tests confirm the cause).
- Treatment for toxins or other triggers if found.
Long‑Term Outlook
Most patients recover completely within weeks or months, though some may develop lasting heart weakness. Follow‑up scans and cardiology visits are essential to check heart recovery. Exercise should be resumed gradually, only after medical clearance.
Seek medical help immediately if you experience new chest pain, shortness of breath, or palpitations—especially after an infection.
