Myocarditis

Myocarditis is a severe condition, and it can lead to serious complications in some cases, but it’s usually treatable.

Myocarditis

Myocarditis occurs due to several reasons, and it causes weakness in the heart muscle, which affects its ability to pump blood throughout the body.

Causes and risk factors of myocarditis

• Viral infections, such as the ones that cause the common cold, COVID-19, and hepatitis B and C.
• Bacterial infections, such as the ones that cause Lyme disease and diphtheria.
• Fungal infections, such as yeast infections, Histoplasma, and molds like aspergillus.
• Parasites, such as toxoplasma and Trypanosoma cruzi.
• As a side effect of certain medications, such as some antibiotics, some cancer treatments, some anti-seizure medicines, and illegal drugs.
• Exposure to radiation and carbon monoxide.
• Certain conditions, such as lupus, giant cell arteritis, rheumatic fever, and Chagas disease.
• The risk of myocarditis increases due to the following factors: young adults, males, excessive alcohol consumption, dialysis, implanted heart devices, diabetes, HIV & AIDS, chest injuries, skin injuries, eating disorders, and end-stage kidney disease.

Symptoms of myocarditis

Myocarditis may not cause any symptoms in some cases. Common symptoms include:

• Shortness of breath.
• Chest pain.
• Heart palpitations.
• Heart arrhythmia.
• Tiredness and weakness.
• Lightheadedness.
• Swelling in the legs and feet.
• Loss of appetite.
• Flu-like symptoms.
• In children, myocarditis causes breathing problems, heart arrhythmia, chest pain, fever, and fainting.
• Severe myocarditis can lead to permanent damage in the heart and cause heart failure, heart attack, stroke, or sudden heart death.

Diagnosis of myocarditis

• Physical exam.
• Blood tests.
• Imaging tests.

Treatment of myocarditis

• Myocarditis often resolves on its own.
• Severe cases may need medications, medical devices like a pacemaker and a left ventricular assist device, or a heart transplant.
