1What Is Pericarditis?
Pericarditis is an inflammatory condition of the pericardium, which is a thin sac with two layers surrounding the heart. It contains a small amount of fluid in between to prevent friction during each heartbeat. When inflammation occurs, it would lead to chest pain. Pericarditis is typically an acute illness that occurs unexpectedly and might last for several days to several weeks. In most cases, the condition can resolve on its own, but treatments are needed to reduce the duration and prevent recurrences. [1]
