Key Takeaways
Pericarditis is inflammation of the thin membrane surrounding the heart called the pericardium
Chest pain that worsens with breathing or lying down is the most common symptom
Most cases are caused by viral infections and heal on their own with proper treatment
Anti-inflammatory medications like NSAIDs are the main treatment for most patients
While usually not serious, some cases can lead to complications that require immediate care
Overview
Pericarditis is an inflammation of the pericardium, the thin, two-layered membrane that surrounds your heart. Think of it like a protective sac that normally contains a small amount of fluid to help your heart move smoothly as it beats. When this membrane becomes inflamed, it can cause sharp chest pain and other uncomfortable symptoms.
This condition affects people of all ages, but it's most common in men between 20 and 50 years old. About 5 out of every 100,000 people develop pericarditis each year. While the chest pain can be scary and intense, most cases are not life-threatening and respond well to treatment.
The good news is that pericarditis often resolves within a few weeks with proper care. However, it's important to get medical attention because the symptoms can be similar to a heart attack. Understanding the signs and getting the right diagnosis helps ensure you receive appropriate treatment and avoid complications.
Doctors diagnose pericarditis by considering your symptoms, physical exam, ECG, echocardiogram, and sometimes blood tests or other imaging. No single test confirms every case. Treatment is usually straightforward and focuses on reducing swelling and pain. Most people recover completely and don't have long-term problems from pericarditis.
Symptoms & Signs
Pericarditis symptoms can develop suddenly or gradually over time. The severity and type of symptoms can vary from person to person, but chest pain is almost always present.
Primary Symptoms
Sharp, stabbing chest pain that may spread to your left shoulder and neck
Pain that worsens when taking deep breaths, coughing, or lying flat
Pain that improves when sitting up and leaning forward
Shortness of breath especially when lying down
Low-grade fever and general feeling of being unwell
Rapid or irregular heartbeat that you may notice as palpitations
Fatigue and weakness that affects your daily activities
Dry cough that may persist for several days
When to Seek Care
Seek urgent medical evaluation for new, unexplained, or persistent chest pain, especially if it occurs with shortness of breath, fainting, sweating, nausea, or fever. Call 911 for severe chest pain, trouble breathing, or fainting. Since pericarditis symptoms can mimic those of a heart attack, it's better to be safe and get evaluated promptly.
Some people describe the pain as feeling like someone is squeezing their chest or sitting on their heart. The pain may come and go or stay constant throughout the day. Keeping track of when your symptoms happen and what makes them better or worse helps your doctor understand your condition.

Causes & Risk Factors
Understanding what causes pericarditis can help you recognize your risk and take steps to prevent it when possible.
Age
Most common in men aged 20-50, but can occur at any age
Recent Illness
Having a recent viral or bacterial infection increases risk
Autoimmune Conditions
Lupus, rheumatoid arthritis, and similar conditions raise risk
Cancer Treatment
Radiation therapy to the chest area can cause pericarditis
Heart Surgery
Recent cardiac procedures may trigger inflammation
Kidney Disease
Advanced kidney disease can lead to uremic pericarditis

Diagnosis
Getting an accurate diagnosis of pericarditis requires a thorough evaluation by a healthcare provider. The process typically involves reviewing your symptoms, medical history, and performing specific tests.
Medical History & Physical Examination
Your doctor will ask detailed questions about your chest pain, including when it started, what makes it better or worse, and any recent illnesses you've had. They'll listen to your heart with a stethoscope, checking for a pericardial friction rub - a scratchy sound that occurs when the inflamed layers of the pericardium rub against each other.
During the physical exam, your doctor will also check for signs of fluid buildup around the heart and assess your overall cardiovascular health. They may ask about recent travel, chest injuries, and family history of heart disease.
Diagnostic Testing
Electrocardiogram (ECG) to check for characteristic changes in heart rhythm and electrical activity
Echocardiogram to look for fluid around the heart and assess heart function
Chest X-ray to rule out other causes of chest pain and check heart size
Blood tests to check for signs of infection, inflammation, and heart damage markers
CT or MRI scan in complex cases to get detailed images of the heart and pericardium

Treatment Options
The main goals of pericarditis treatment are to reduce inflammation, relieve pain, and prevent complications. Most people respond well to medication and can manage their condition at home.
Conservative Treatments
Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen to reduce inflammation and pain
Colchicine an anti-inflammatory medication that helps prevent recurrent episodes
Rest and activity modification to avoid straining the heart while it heals
Your healthcare team may suggest additional comfort measures for pain, based on your symptoms and medical history.
Advanced Treatments
Corticosteroids when NSAIDs and colchicine aren't effective or well-tolerated
Pericardiocentesis a procedure to drain excess fluid if cardiac tamponade develops
Pericardiectomy surgical removal of the pericardium in severe, chronic cases
For patients with other underlying conditions, treatment may need to be adjusted to account for these factors.
Most doctors start with NSAIDs like ibuprofen because they work well and have fewer side effects than other options. You may need to take these medications for several weeks to fully reduce the inflammation. Your doctor will monitor your progress and adjust your treatment plan if needed.
Living with the Condition
Managing pericarditis involves making some temporary lifestyle adjustments while your body heals. Most people can return to normal activities within a few weeks.
Daily Management Strategies
Take your medications as prescribed, even if you start feeling better. Keep a symptom diary to track your progress and identify any patterns or triggers. Get plenty of rest and avoid strenuous activities until your doctor clears you. Stay hydrated and eat a heart-healthy diet rich in fruits, vegetables, and whole grains.
Talk to your family and friends about what you're going through so they can support you during recovery. Let them know when you need help with household tasks or daily activities. It's okay to ask for help, and resting properly is one of the most important parts of healing.
Exercise & Movement
During the acute phase, avoid intense exercise and heavy lifting. Ask your doctor what activity is safe for you during recovery. As you recover, gradually increase your activity level under your doctor's guidance. As you recover, gradually increase your activity level under your doctor's guidance. Most people can return to full activity, including sports, once the inflammation resolves completely.
Your doctor will tell you when it's safe to start exercising again, which is usually after a few weeks of rest. Don't rush back to your normal routine too quickly, as this can cause symptoms to return. Be patient with yourself and celebrate small steps forward in your recovery.
Prevention
While you can't prevent all cases of pericarditis, especially those caused by viral infections, there are steps you can take to reduce your risk.
Practice good hygiene by washing your hands frequently to prevent viral and bacterial infections
Get recommended vaccinations, including annual flu shots, to reduce infection risk
Avoid smoking, which can worsen inflammation and harm overall heart health
Manage underlying autoimmune conditions with proper medical care and medication adherence
Seek prompt treatment for respiratory infections and other illnesses that could spread to the pericardium
Follow safety precautions to avoid chest injuries during sports and other activities
Staying healthy overall is the best way to prevent pericarditis caused by infections. Keep your immune system strong by getting enough sleep, eating nutritious food, and managing stress. If you have an autoimmune disease, taking your medications correctly helps prevent pericarditis from developing.
Protect yourself during sports and physical activities by wearing appropriate safety gear when needed. If you've had pericarditis before, let your doctor know if you start having similar symptoms. Seek medical care for infections when symptoms are severe, persistent, or concerning, and follow your clinician's treatment advice.
Frequently Asked Questions
Can pericarditis come back?
Yes, pericarditis can recur in about 15-30% of patients, usually within the first few months after the initial episode.
Most people feel significantly better within 1-2 weeks of starting treatment, with complete recovery typically occurring within 2-6 weeks. However, some people may need several months to fully recover, especially if complications develop.
Pericarditis itself is not contagious, but the underlying viral infection that caused it might be. If you have pericarditis due to a viral infection, you should take precautions to avoid spreading the virus to others.
You should avoid intense exercise and competitive sports during the acute phase of pericarditis. Light activities like walking are usually safe, but always check with your doctor before resuming any exercise routine.
While both can cause chest pain, pericarditis pain typically worsens with breathing and improves when sitting up and leaning forward. Heart attack pain is usually more constant and may be accompanied by nausea, sweating, and arm pain. However, since the symptoms can overlap, it's important to seek medical evaluation for any chest pain.
