Depending on the timing of presentation and duration, pericarditis is divided into "acute" and "chronic" forms. Clinically, acute pericarditis presents within 6 weeks of the disease onset; subacute pericarditis presents within 6 weeks to 6 months of the disease onset; and chronic pericarditis manifests after 6 months of the disease onset.[[Acute pericarditis]] is more common than chronic pericarditis, and often occurs as a complication of viral infections, immunologic conditions, or as a result of a [[heart attack]] ([[myocardial infarction]]). Chronic pericarditis is less common, which may manifest as scarring of the pericardium a condition known as [[constrictive pericarditis]]. | |||

Overview
Pericarditis may:
- Present as part of a generalized disease
- Present as an isolated disease
- Present as part of a disease that affects nearby organs
- Present as part of multiple diseases
Classification
Pericarditis can be classified according to the composition of the inflammatory exudate or the composition of the fluid that accumulates around the heart.[1]
Types include:
Acute Versus Chronic Pericarditis
Depending on the timing of presentation and duration, pericarditis is divided into "acute" and "chronic" forms. Clinically, acute pericarditis presents within 6 weeks of the disease onset; subacute pericarditis presents within 6 weeks to 6 months of the disease onset; and chronic pericarditis manifests after 6 months of the disease onset.Acute pericarditis is more common than chronic pericarditis, and often occurs as a complication of viral infections, immunologic conditions, or as a result of a heart attack (myocardial infarction). Chronic pericarditis is less common, which may manifest as scarring of the pericardium a condition known as constrictive pericarditis.
