Pericarditis can be attributed to several factors, including viral, bacterial, fungal and other infections. Other possible causes of pericarditis include heart attack or heart surgery, other medical conditions, injuries and medications.
Pericarditis can be acute, meaning it happens suddenly and typically doesn’t last long. Or the condition may be "chronic," meaning that it develops over time and may take longer to treat.
Both types of pericarditis can disrupt your heart’s normal function. In rare cases, pericarditis can have very serious consequences, possibly leading to abnormal heart rhythm and death.
