In short
The pericardium is a membrane or sac that surrounds the heart, holding it in place and helping it work properly. Problems with this membrane include pericarditis, which is an inflammation of the sac, pericardial effusion, which is a buildup of fluid, and cardiac tamponade, a serious condition where fluid buildup causes heart function problems. Symptoms of pericardial problems include chest pain, rapid heartbeat, and difficulty breathing, while fever is a common symptom of acute pericarditis.

Codes
Description
The pericardium is a membrane, or sac, that surrounds your heart. It holds the heart in place and helps it work properly. Problems with the pericardium include:
- Pericarditis - an inflammation of the sac. It can be from a virus or other infection, a heart attack, heart surgery, other medical conditions, injuries, and certain medicines.
- Pericardial effusion - the buildup of fluid in the sac
- Cardiac tamponade - a serious problem in which buildup of fluid in the sac causes problems with the function of the heart
Symptoms of pericardial problems include chest pain, rapid heartbeat, and difficulty breathing. Fever is a common symptom of acute pericarditis. Your doctor may use a physical exam, imaging tests, and heart tests to make a diagnosis. Treatment depends on the cause.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
