What is pericarditis?
Pericarditis is swelling and irritation of the pericardium, which is the sac that surrounds your heart.
Pericarditis usually doesn't cause serious problems. Most people get better in 7 to 10 days. When there are problems, they may include:
- A buildup of fluid in the pericardial sac (pericardial effusion).
- Sudden pressure on the heart and sudden difficulty pumping enough blood (called cardiac tamponade). This can be caused by the weight and pressure of the fluid buildup if it happens quickly.
- Constrictive pericarditis, in which the sac around the heart gets thick and stiff. This makes it harder for the heart to pump blood.
