Pericarditis Adult

Causes

The cause of pericarditis is often unknown. However, possible causes include:

• Viral, bacterial, or fungal infection
• Heart attack
• Inflammatory diseases such as rheumatoid arthritis or lupus
• Cancer that has spread from a tumor near the heart
• Kidney failure
• Injury or surgery affecting the chest, esophagus, or heart
• Radiation treatment
• Certain medications used to suppress the immune system

Risk Factors

Factors that increase your chance of getting pericarditis include:

• A weakened immune system that is not able to fight off infections and other diseases
• Any of the causes listed above

Symptoms

Chest pain is a common symptom of pericarditis, especially over the left side or center of the chest. It sometimes spreads to the neck and left shoulder. It is usually a sharp, stabbing pain. Deep breathing or lying down may worsen the pain. Sitting up may lessen it. Other symptoms may include:

• Shortness of breath
• Coughing
• Fever and chills
• Pain when swallowing
• Weakness and fatigue

Diagnosis

The doctor will ask about your symptoms and medical history. A physical exam will be done. A stethoscope will be used to listen for a grating or rubbing sound in your heart. If the condition is severe, there may be a crackle sound in your lungs. The following tests may be performed:

Images of your heart may need to be taken. This can be done with:

• Chest x-ray
• Electrocardiograph (ECG or EKG)
• Echocardiogram
• Heart or chest MRI or CT scan

Your bodily fluid may need to be tested. This can be done with:

• Blood tests
• Pericardiocentesis

Treatment

Treating pericarditis depends on the cause, if the cause is known. In many cases, when the cause is unknown or viral pericarditis is suspected, pain relievers and anti-inflammatory medications are given. In other cases, corticosteroids may be given. If the condition is caused by a bacterial infection, antibiotics are used.

If the fluid is seriously affecting the heart’s ability to pump, the fluid may need to be removed through pericardiocentesis, which is the same procedure used for testing. In rare cases, surgery may be performed.

Depending on the cause of the pericarditis, the illness can range from mild to life-threatening. Acute inflammatory pericarditis usually subsides with treatment within a few weeks or months. However, pericarditis caused by chronic inflammatory diseases, like lupus or rheumatoid arthritis, may last longer or tend to recur.

If you are diagnosed with pericarditis, follow your doctor’s instructions .

Prevention

There is no known way to prevent pericarditis.
