Pericarditis is an inflammation of the pericardium, which is the thin sac that surrounds the heart. It can be caused by infections, autoimmune disorders, or other underlying conditions. Symptoms of pericarditis include fever and chest pain that worsens with deep breathing but improves with sitting up and leaning forward.

There is also pericardial effusion, which refers to the accumulation of excess fluid in the pericardium. Pericardial effusion can be caused by a variety of conditions, including pericarditis, heart attack, autoimmune disorders, and cancer. Symptoms of the pericardial effusion may include chest pain, difficulty breathing, and fatigue.
