Acute pericarditis is more common than chronic pericarditis, and can occur as a complication of infections, immunologic conditions, or heart attack.
The classic sign of pericarditis is a friction rub. Other signs include diffuse ST-elevation and PR-depression on ECG (all leads); cardiac tamponade (pulsus paradoxus with hypotension), and congestive heart failure (elevated jugular venous pressure with peripheral edema).
Since the mid-19th Century, retrospective diagnosis of pericarditis has been made upon the finding of adhesions of the pericardium.
Fibrinous pericarditis is an exudative inflammation. The pericardium is infiltrated by the fibrinous exudate. This consists of fibrin strands and leukocytes. Fibrin describes an amorphous, eosinophilic (pink) network. Leukocytes (mainly neutrophils) are found within the fibrin deposits and intrapericardic. Vascular congestion is also present. The myocardium has no changes. Sometimes referred to as having "Bread and Butter Appearance". Photo at: Atlas of Pathology
