Nonarrhythmic complications of acute myocardial infarction.

Complications of acute myocardial infarction can be categorized as nonarrhythmic or arrhythmic; the latter is discussed elsewhere. Patients are at risk for a number of potentially serious or fatal complications during or after the acute infarction phase. These include shock, left ventricular free wall rupture, rupture of the interventricular septum, papillary muscle rupture, ventricular pseudoaneurysm, and stroke. Right ventricular infarction, which is typically associated with inferior myocardial infarction, will also be discussed.
