What Is Pericarditis?

Sudden, sharp chest pain is always alarming. While many people immediately think of a heart attack, there are other heart-related conditions that can cause chest pain too. One of them is pericarditis. So, what is pericarditis? It is inflammation of the pericardium, the thin, two-layered sac that surrounds and protects your heart.

Pericarditis is often mild and treatable, but its symptoms can look a lot like a heart attack, and it can sometimes lead to serious complications. That is why any new chest pain should be checked right away. Memorial Springs ER in Spring, TX, is open 24/7 with an EKG, imaging, and on-site lab testing to find the cause quickly.

Understanding Pericarditis and Its Types

The pericardium has two thin layers with a small amount of fluid between them. This fluid lets your heart move smoothly as it beats. When the pericardium becomes inflamed, the layers can rub against each other, causing sharp chest pain.

Pericarditis is classified by how long it lasts:

• Acute pericarditis: comes on suddenly and usually clears up within 4 to 6 weeks.
• Recurrent pericarditis: returns after a period without symptoms.
• Chronic pericarditis: lasts longer than three months.
• Constrictive pericarditis: a rare form where the pericardium becomes stiff and scarred, limiting how well the heart can fill with blood.

What Causes Pericarditis?

In many cases, doctors cannot find an exact cause. When a cause is found, it may include:

• Viral infections: the most common known cause, often after a cold, flu, or stomach virus.
• Bacterial or fungal infections: less common but more serious.
• Heart attack or heart surgery: inflammation can develop days or weeks afterward.
• Autoimmune diseases: conditions such as lupus or rheumatoid arthritis.
• Kidney failure: waste buildup in the blood can irritate the pericardium.
• Chest injury: trauma, such as from a car accident.
• Certain medicines and cancer treatments: some drugs and chest radiation can inflame the pericardium.

Symptoms of Pericarditis

The most common symptom is chest pain that:

• Feels sharp or stabbing, usually behind the breastbone or on the left side.
• Gets worse when you take a deep breath, cough, swallow, or lie flat.
• Feels better when you sit up and lean forward.
• May spread to your neck, shoulders, or back.

Other symptoms can include a low-grade fever, weakness, heart palpitations, shortness of breath when lying down, and swelling in the legs or abdomen.

Pericarditis vs. Heart Attack

Pericarditis and heart attacks can feel similar, and it is not safe to guess which one you have. Heart attack pain is more often described as pressure, squeezing, or heaviness, and it usually does not change with position or breathing. Pericarditis pain is typically sharp and changes when you move or breathe deeply.

Only medical testing can tell the difference. Our chest pain emergency room team can quickly run the tests needed to rule out a heart attack.

When to Go to the ER

Call 911 or go to the ER right away if you have:

• Chest pain that is new, severe, or does not go away.
• Chest pain with shortness of breath, sweating, nausea, or lightheadedness.
• Fainting or a very fast or irregular heartbeat.
• Swelling in your legs, feet, or belly along with trouble breathing.

Never drive yourself to the ER if you think you may be having a heart problem.

How Pericarditis Is Diagnosed

Doctors use several tools to diagnose pericarditis, including:

• Listening to your heart: a scratchy sound called a pericardial rub is a classic sign.
• Electrocardiogram (EKG): shows patterns linked to pericarditis.
• Chest X-ray: checks the size and shape of the heart.
• Echocardiogram: an ultrasound that shows fluid around the heart.
• Blood tests: check for inflammation, infection, and heart muscle damage.

Treatment and Recovery

Most people with acute pericarditis recover within a few weeks. Treatment often includes anti-inflammatory medicines such as ibuprofen or aspirin and a medicine called colchicine, which lowers the risk of the condition coming back. Rest is important, and athletes are usually told to avoid strenuous exercise for at least three months.

If you have ongoing heart symptoms or risk factors, follow-up cardiac care near me and regular checkups with your doctor or a cardiologist are important.

Possible Complications

• Cardiac tamponade: fluid builds up around the heart and presses on it, which is a medical emergency.
• Recurrent pericarditis: symptoms come back after treatment.
• Constrictive pericarditis: long-term scarring that limits heart function.

Frequently Asked Questions

Is Pericarditis Serious?

Most cases are mild and improve with treatment, but complications such as cardiac tamponade can be life-threatening. Prompt diagnosis is important, so get new chest pain checked right away.

Can Pericarditis Go Away on Its Own?

Mild cases may improve on their own, but treatment helps relieve pain faster and lowers the risk of recurrence. A doctor can confirm the cause and decide which medicines you need.

Can Stress Cause Pericarditis?

Stress does not directly cause pericarditis, but it can weaken your immune system and may play a role in flare-ups. Managing stress can support your recovery, though it does not replace medical treatment.

Can You Exercise With Pericarditis?

Not until your doctor says it is safe. Doctors usually recommend avoiding strenuous activity until symptoms and test results return to normal, and athletes may need to rest for at least three months.
