Complications of acute myocardial infarction can be categorized as nonarrhy
thmic or arrhythmic; the latter is discussed elsewhere. Patients are at ris
k for a number of potentially serious or fatal complications during or afte
r the acute infarction phase. These include shock, left ventricular free wa
ll rupture, rupture of the interventricular septum, papillary muscle ruptur
e, ventricular pseudoaneurysm, and stroke. Right ventricular infarction, wh
ich is typically associated with inferior myocardial infarction, will also
be discussed.
