Myocarditis

21:55 - 4 May , 2021

Disease

What is Myocarditis?

It is a condition in which the myocardium or heart muscle becomes inflamed causing arrhythmias and a deficiency in the pumping of blood that can lead to the formation of clots and trigger a stroke or heart attack. There are several causes for the appearance of this anomaly, including:
  • Bacterial infections.
  • Fungal infections.
  • Parasites.
  • Viral infections.
Occasionally, myocarditis can result from a medication allergy, illicit drugs, exposure to certain chemicals, or the presence of other diseases such as lupus.

Symptoms

Symptoms vary depending on the cause that originates the myocarditis, but, in general, it includes:
  • Chest pain.
  • Edema in legs, feet, and ankles.
  • Trouble breathing.
  • Tiredness.
  • Arrhythmia.
If it is caused by a viral, bacterial, or fungal infection, the characteristic symptoms are:
  • Diarrhea.
  • Joint pain.
  • Headache.
  • Sore throat.
  • High fever.
Potential risks: Myocarditis usually goes away without sequelae, but it can sometimes seriously affect the heart, causing:
  • Stroke.
  • Arrhythmias.
  • Heart attack.
  • Heart failure.
  • Death.

Diagnosis and treatment

Once your doctor analyzes your symptoms and clinical history, they will perform a physical examination and request blood tests and diagnostic tests such as:
  • Echocardiogram.
  • Electrocardiogram.
  • Chest x-ray.
  • MRI.
  • Catheterization.
  • Heart muscle biopsy.
The treatment to be followed will depend on the cause of the condition and the severity of the symptoms. You may be prescribed painkillers, anti-inflammatories, cardiac drugs, and corticosteroids, but if you have severe myocarditis, you will require intensive treatment, which includes intravenous medications, a ventricular assist device to help pump blood back into your body, the implantation of a catheter, and in extreme cases, a heart transplant.
