title: Post-Myocardial Infarction Pericarditis.
abstract: Post-myocardial infarction pericarditis occurs in approximately 5% to 6% of patients who receive thrombolytic agents. It should be suspected in any patient with pleuropericardial pain. A pericardial friction rub may or may not be present. Differentiation of pericarditis from recurrent angina may be difficult, but a careful history and evaluation of serial electrocardiograms can help distinguish the two entities. Dressler's syndrome, pericarditis that occurs at least 1 week following myocardial infarction, is now exceedingly rare. Most cases of pericarditis have a benign course; however, because pericarditis is associated with larger infarcts, overall long-term mortality rate is increased. Rare complications include hemopericardium, cardiac tamponade, and constrictive pericarditis. Therapy is directed toward relief of pain, which usually responds well to nonsteroidal anti- inflammatory agents (eg, aspirin or ibuprofen).
