Pericarditis, a condition affecting the protective sac surrounding the heart, can cause significant discomfort and concern for those experiencing it. This inflammatory disorder of the pericardium, the thin membrane encasing the heart, can result in chest pain and other troubling symptoms. Understanding pericarditis is crucial for early detection and proper management, as it can have an impact on overall heart health and quality of life.
This article aims to shed light on the key aspects of pericarditis, including its common symptoms, underlying causes, and available treatment options. We’ll explore how healthcare providers diagnose this condition, discuss potential risk factors, and examine various approaches to manage and treat pericarditis. By delving into these topics, readers will gain valuable insights to better understand and address this heart-related issue.
Understanding Pericarditis
Pericarditis is an inflammation of the pericardium, the thin, two-layered, fluid-filled sac that surrounds the heart to hold it in place and help protect it from damage caused by infection and malignancy. The pericardium consists of two layers with a small amount of fluid between them, which reduces friction as the heart beats. When the layers become inflamed, they may rub against each other, causing chest pain, a common symptom of pericarditis.
Pericarditis can be acute, meaning it develops suddenly and typically doesn’t last long, or chronic, lasting for more than three months and requiring longer treatment. Both types of pericarditis have the potential to disrupt the heart’s normal function and, in rare cases, lead to serious consequences.
Types of Pericarditis
- Acute pericarditis: Symptoms last less than four to six weeks.
- Incessant pericarditis: Symptoms persist for more than four to six weeks but less than three months despite therapy.
- Chronic pericarditis: Symptoms last for more than three months.
- Recurrent pericarditis: Pericarditis develops for a second time after having no symptoms for at least four weeks.
Other classifications of pericarditis include:
- Infectious pericarditis: Develops as a result of viral, bacterial, fungal, or parasitic infection.
- Idiopathic pericarditis: Has no known cause.
- Traumatic pericarditis: Develops as a result of chest injury, such as after a car accident.
- Uremic pericarditis: Develops as a result of kidney failure.
- Malignant pericarditis: Develops as a result of cancer growth in the body.

Pericarditis vs. Myocarditis
While both pericarditis and myocarditis are types of inflammation affecting the heart, they involve different areas of the organ. Pericarditis is an inflammation of the pericardium, the lining around the heart, while myocarditis is an inflammation of the heart muscle itself (myocardium).
Most often, a virus causes both pericarditis and myocarditis. The two conditions can cause chest pain, but the pain associated with pericarditis usually improves when sitting up and leaning forward. In contrast, myocarditis typically causes fatigue and weakness.
Understanding the differences between pericarditis and myocarditis is crucial for accurate diagnosis and appropriate treatment. Healthcare providers use various diagnostic tools, such as physical examinations, imaging tests, and blood tests, to differentiate between the two conditions and determine the best course of action for each patient.
Symptoms and Diagnosis
The symptoms of pericarditis can vary from person to person, but they typically include sharp, stabbing chest pain that may worsen when lying down or taking deep breaths. The pain often improves when sitting up and leaning forward. Other common symptoms include a dry cough, trouble breathing when lying down, and a feeling of anxiety or fatigue. In some cases, individuals may experience fever, palpitations, or swelling in the legs, feet, and ankles.
To diagnose pericarditis, healthcare providers conduct a thorough examination and ask questions about the patient’s symptoms and medical history. They listen to the heart using a stethoscope to detect a specific sound called a pericardial rub, which occurs when the inflamed layers of the pericardium rub against each other. This sound is best heard along the lower left sternal border.
Common Symptoms
- Sharp, stabbing chest pain that worsens with deep breaths or when lying down
- Pain that improves when sitting up and leaning forward
- Pain that may radiate to the back, neck, or left shoulder
- Dry cough
- Trouble breathing when lying down
- Anxiety or fatigue
- Fever
- Palpitations
- Swelling in the legs, feet, and ankles (in severe cases)
Diagnostic Tests
To confirm the diagnosis of pericarditis and rule out other conditions with similar symptoms, healthcare providers may order several tests:
- Electrocardiogram (ECG): An ECG records the electrical signals in the heart and can show characteristic changes in pericarditis, such as widespread ST-segment elevation and PR-segment depression.
- Echocardiogram: This test uses sound waves to create images of the heart, allowing healthcare providers to assess the presence of pericardial effusion and evaluate heart function.
- Chest X-ray: A chest X-ray can show changes in the size and shape of the heart and detect the presence of fluid in the lungs.
- Blood tests: These tests check for signs of inflammation, infection, and heart damage. Common blood tests include complete blood count (CBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and cardiac enzymes like troponin.
- Cardiac computed tomography (CT) or magnetic resonance imaging (MRI): These advanced imaging techniques may be used to visualize the pericardium and surrounding structures in more detail, especially if the diagnosis is uncertain or complications are suspected.

Differential Diagnosis
Several conditions can present with symptoms similar to those of pericarditis, making it essential for healthcare providers to consider alternative diagnoses:
- Acute myocardial infarction (heart attack)
- Pleurisy (inflammation of the lung lining)
- Pneumonia
- Pulmonary embolism
- Costochondritis (inflammation of the cartilage connecting the ribs to the breastbone)
- Gastroesophageal reflux disease (GERD)
- Anxiety or panic disorders
By carefully evaluating the patient’s symptoms, physical examination findings, and test results, healthcare providers can accurately diagnose pericarditis and differentiate it from other conditions. This enables them to provide appropriate treatment and manage the condition effectively.
Causes and Risk Factors
Pericarditis can have various causes, both infectious and non-infectious in nature. In many cases, the exact cause remains unknown, leading to a diagnosis of idiopathic pericarditis. Understanding the potential causes and risk factors associated with this condition is crucial for accurate diagnosis and appropriate treatment.
Infectious Causes
Viral infections are the most common cause of pericarditis, with coxsackieviruses A and B, echovirus, adenoviruses, parvovirus B19, HIV, influenza, and herpes viruses like EBV and CMV being the primary culprits. Bacterial pericarditis is less frequent in developed countries but remains prevalent in developing nations, with tuberculosis being the most common cause, especially in HIV-positive patients. Other bacterial causes include Coxiella burnetii, Meningococcus, Pneumococcus, Staphylococcus, and Streptococcus. In rare cases, fungal organisms such as Histoplasma, Coccidioides, Candida, and Blastomyces, or parasitic species like Echinococcus and Toxoplasma can lead to pericarditis, particularly in immunocompromised individuals.
Non-Infectious Causes
Non-infectious causes of pericarditis are diverse and include malignancy, connective tissue diseases, metabolic disorders, trauma, and certain medications. Malignant pericarditis often results from metastatic disease, while connective tissue diseases such as systemic lupus erythematosus, rheumatoid arthritis, and Behçet’s disease can trigger pericardial inflammation. Metabolic conditions like uremia and myxedema, as well as chest injuries from accidents or surgery, can also cause pericarditis. Dressler syndrome, a delayed inflammatory response following a myocardial infarction, is another recognized cause. Additionally, certain medications, including procainamide, hydralazine, and checkpoint inhibitors used in cancer treatment, have been implicated in drug-induced pericarditis.
Risk Factors
Several factors can increase an individual’s risk of developing pericarditis:
- Age and gender: Pericarditis is more common in men and people assigned male at birth between the ages of 16 and 65.
- Recent viral infections: A history of recent viral infections, particularly those affecting the gastrointestinal system, can increase the risk of pericarditis.
- Autoimmune disorders: Individuals with autoimmune conditions such as lupus, rheumatoid arthritis, and scleroderma are at a higher risk of developing pericarditis.
- Kidney failure: Uremic pericarditis can occur as a complication of kidney failure.
- Cancer: Malignancies, especially those that have metastasized, can lead to malignant pericarditis.
- Cardiac procedures: Recent heart surgery, percutaneous interventions, or radiation therapy can increase the risk of pericarditis.
- Chest trauma: Blunt chest injuries from accidents or physical trauma can trigger pericardial inflammation.
Recognizing these risk factors and understanding the various causes of pericarditis is essential for healthcare providers to promptly diagnose and manage this condition effectively. By identifying the underlying etiology, targeted treatment strategies can be implemented to alleviate symptoms, prevent complications, and improve patient outcomes.
Treatment and Management
The treatment of pericarditis focuses on reducing pain and inflammation, addressing the underlying cause, and monitoring for potential complications. The specific approach depends on the type and severity of the condition, as well as the individual’s overall health.
Medications
- Non-steroidal anti-inflammatory drugs (NSAIDs): NSAIDs, such as ibuprofen and aspirin, are often the first line of treatment for pericarditis. These medications help reduce pain and inflammation. High-dose aspirin is commonly prescribed, and patients may need to take NSAIDs for several weeks.
- Corticosteroids: In cases where NSAIDs are ineffective or not well-tolerated, low to moderate doses of corticosteroids may be prescribed. However, steroids are associated with a higher risk of recurrence and are typically reserved for specific situations, such as autoimmune diseases or pregnancy.
- Antibiotics: If a bacterial infection is identified as the cause of pericarditis, appropriate antibiotic therapy will be initiated to target the specific pathogen.

Procedures
- Pericardiocentesis: When a significant amount of fluid accumulates in the pericardial space (pericardial effusion), a procedure called pericardiocentesis may be necessary. This involves inserting a needle or catheter into the chest wall to drain the excess fluid, relieving pressure on the heart.
- Pericardial window: In some cases, a surgical procedure known as a pericardial window may be performed to create an opening in the pericardium, allowing for ongoing drainage of the fluid.
- Pericardiectomy: For individuals with severe constrictive pericarditis, where the pericardium becomes thick and scarred, a pericardiectomy may be required. This surgical procedure involves removing part or all of the pericardium to restore normal heart function.
Lifestyle Changes
- Rest: During the acute phase of pericarditis, it is essential to get adequate rest and avoid strenuous physical activity until symptoms have resolved and the heart has returned to normal function.
- Gradual return to activity: Once symptoms have improved, individuals should work with their healthcare provider to develop a plan for gradually resuming physical activities and exercise.
- Monitoring: Regular follow-up appointments with a cardiologist are crucial to monitor the progress of treatment, assess for potential complications, and make necessary adjustments to the management plan.
It is important to note that the duration of treatment for pericarditis can vary depending on the underlying cause and the individual’s response to therapy. While acute pericarditis often resolves within a few weeks, chronic or recurrent cases may require longer-term management.
By working closely with a healthcare provider and adhering to the prescribed treatment plan, individuals with pericarditis can effectively manage their symptoms, reduce the risk of complications, and improve their overall quality of life.
