Pericarditis is a condition in which the sac surrounding your heart, called the pericardium, becomes swollen and inflamed. You can develop this condition after having a heart attack. Your risk is higher if you’ve had other heart attacks, a serious chest injury, or open-heart surgery. Pericarditis can be treated, but there’s a chance that it could return. It can be life threatening when left untreated.
After a heart attack, your immune system tries to fix the resulting damage to your heart tissue. In cases of pericarditis, instead of repairing this damage, your body’s immune response causes inflammation in the layers of tissue that surround your heart. The exact reason why this happens isn’t known. This condition occurs in about 10 percent of people who have heart attacks, according to American Medical Association Guide to Preventing and Treating Heart Disease (Lipsky, et al., 2008).
One type of pericarditis occurs within two to five days following a heart attack. The other type, known as Dressler’s syndrome, occurs weeks or months after you’ve had a heart attack. Both types are believed to occur as a result of your body’s attempt to repair itself.
How soon after a heart attack that your symptoms start will depend on which type of pericarditis you have.
One of the most common symptoms of pericarditis is chest pain. It might feel like a sharp pain or you may feel tightness in your chest. The pain might be worse when you’re inhaling or lying down. It might also disappear when you move to an upright position. You might feel the pain spread to your neck, back, shoulders, or abdomen. You should call your doctor if you have pain that lasts longer than a few minutes.
Other symptoms include:
Untreated pericarditis can lead to serious complications.
This condition occurs when fluids build up inside your pericardium, increasing the pressure on your heart and making it harder for the heart to pump blood. Cardiac tamponade is rare but can be life threatening. It requires immediate medical treatment.
This condition occurs when your pericardium becomes too thick or is covered by scars due to chronic inflammation or multiple cases of pericarditis. It makes it more difficult for your heart to pump blood. This condition is rare and can be life threatening when left untreated.
This chronic condition occurs when your heart is unable to pump the right amount of blood to the rest of your body. This causes fluids to build up in other parts of your body, including your liver, lungs, arms, legs, and gastrointestinal tract. This condition can be controlled with medicine and lifestyle changes in most cases.
Your doctor will listen to your heart with a stethoscope. A scratchy or rubbing sound could indicate inflammation. A heartbeat that sounds distant is often associated with a fluid buildup. This occurs more often with Dressler’s syndrome.
Other tests might include:
Treatment of pericarditis is done to decrease inflammation and manage pain and other symptoms.
Over-the-counter pain relievers, such as aspirin, ibuprofen, and naproxen are often used to treat pericarditis.
Prescription drugs, such as colchicine and corticosteroids, are used when over-the-counter drugs aren’t effective. Colchicine reduces inflammation and is sometimes used for persistent or recurring pericarditis. However, it can cause kidney or liver damage in people with certain health issues. Corticosteroids also reduce inflammation, but they’re only prescribed if other drugs don’t work. They can cause severe side effects and make it harder for heart tissue to heal.
You might need to have excess fluid drained if you have a more severe case of Dressler’s syndrome. This procedure, known as pericardiocentesis, is done by inserting a needle or thin tube into your chest to drain the fluid.
You might need to have your pericardium surgically removed if it’s scarred or thick enough to prevent your heart from functioning normally. This procedure is called a pericardiectomy.
You can reduce your chances of having a heart attack by adopting a heart-healthy lifestyle and treating conditions that are associated with a higher heart attack risk. This helps lower your risk of developing coronary heart disease, which is a leading cause of heart attacks.
A diet that’s good for your heart includes plenty of fruits and vegetables. You should also eat whole grains, lean meats, and low-fat dairy products. Avoid eating foods that are high in saturated fat, sodium, cholesterol, added sugars, and trans fat.
Being physically active helps keep your heart healthy and helps you lose excess weight. If you don’t exercise on a regular basis or if you have certain health conditions, such as heart disease, ask your doctor to recommend a safe exercise routine.
If you’re obese or overweight, losing excess body fat can lower your risk of having a heart attack. Ask your doctor for advice on controlling your weight through diet and exercise.
Take steps to quit smoking as soon as possible. Smoking is associated with a higher risk of having a heart attack. You should also limit your exposure to secondhand smoke.
Conditions such as diabetes, high blood pressure, and high cholesterol can raise your heart attack risk. Follow your doctor’s recommendations for treating these conditions.
