Following a myocardial infarction (MI), patients are at risk for a variety of cardiac complications. Many complications are mechanical (eg, papillary muscle rupture, left ventricular wall rupture, or ventricular septal rupture) and are related to the extent of myocardial injury, while other post-MI complications are immunologic, inflammatory, or iatrogenic.
Three major types of pericardial complications can occur in patients following a myocardial infarction:
●Early infarct-associated pericarditis (often termed peri-infarction pericarditis)
●Pericardial effusion (with or without tamponade)
●Postcardiac injury (Dressler's) syndrome
