Understanding Pericarditis: Symptoms, Causes, Diagnosis, and Treatment

What is Pericarditis?

Pericarditis is swelling or irritation of the pericardium. The pericardium is a thin, two-layered sac that surrounds your heart. This condition can cause sharp chest pain. Often, the pain gets worse when you breathe in or lie down. Although pericarditis can be mild, it sometimes leads to serious problems. According to the Centers for Disease Control and Prevention (CDC), pericarditis affects people of all ages. However, it is most common in adults between 20 and 50 years old.

Common Symptoms of Pericarditis

Pericarditis symptoms can vary. Some people have mild discomfort, while others feel severe pain. For example, you may notice:

  • Sharp, stabbing chest pain, often behind the breastbone
  • Pain that worsens when lying down or taking deep breaths
  • Pain that improves when sitting up or leaning forward
  • Shortness of breath, especially when reclining
  • Low-grade fever
  • Fatigue or weakness
  • Heart palpitations (feeling like your heart is racing)
  • Sometimes, symptoms may be mild and easy to miss. Therefore, it is important to pay attention to any new or unusual chest pain.

    Causes and Risk Factors

    There are many possible pericarditis causes. Most often, a viral infection triggers the condition. However, other causes include:

  • Bacterial or fungal infections
  • Heart attack or recent heart surgery
  • Autoimmune diseases, such as lupus or rheumatoid arthritis
  • Injury to the chest
  • Cancer near the heart
  • Certain medications
  • Some people have a higher risk. For instance, those with weakened immune systems or recent chest injuries are more likely to develop pericarditis. Additionally, men between 20 and 50 years old are at greater risk.

    How Pericarditis is Diagnosed

    Doctors use several steps to make a pericarditis diagnosis. First, they ask about your symptoms and medical history. Next, they perform a physical exam. Often, doctors listen for a special sound called a “pericardial rub” with a stethoscope. This sound can help confirm pericarditis.

    To be sure, your doctor may order tests, such as:

  • Electrocardiogram (ECG) to check your heart’s electrical activity
  • Chest X-ray to look for fluid around the heart
  • Echocardiogram (heart ultrasound) to see the pericardium
  • Blood tests to find signs of infection or inflammation
  • These tests help rule out other causes of chest pain, such as a heart attack.

    Treatment Options for Pericarditis

    Pericarditis treatment depends on the cause and severity. Most cases improve with simple care. For example, doctors may recommend:

  • Rest and avoiding strenuous activity
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen
  • Colchicine to reduce swelling and prevent recurrence
  • Corticosteroids for severe or persistent cases
  • In rare cases, fluid may build up around the heart. This is called pericardial effusion. If this happens, doctors may need to drain the fluid. According to the World Health Organization (WHO), most people recover fully with proper treatment.

    Lifestyle Tips and Prevention

    While you cannot always prevent pericarditis, some steps may lower your risk. For instance:

  • Wash your hands often to avoid infections
  • Manage chronic illnesses, such as diabetes or autoimmune diseases
  • Follow your doctor’s advice after heart surgery or injury
  • Take medications as prescribed
  • Additionally, staying healthy and active can support your heart. However, always check with your doctor before starting new activities if you have heart problems.

    When to See a Doctor

    Sometimes, chest pain can signal a serious problem. Therefore, seek medical help right away if you have:

  • Severe or sudden chest pain
  • Shortness of breath
  • Fainting or dizziness
  • Swelling in your legs or abdomen
  • Early diagnosis and treatment can prevent complications. If you suspect pericarditis or have ongoing chest pain, do not wait to get help.

    Consult a cardiologist for personalized advice if you suspect pericarditis or experience chest pain.
