Acute myocardial infarction occurs after a period of profound myocardial ischemia. Ischemia of this degree immediately produces a regional contraction abnormality, which is readily detectable by echocardiography before the onset of necrosis. Echocardiography has been used both experimentally and clinically as a guide to the functional extent of myocardial involvement in evolving infarction and hence provides an objective anatomic basis for electing therapeutic interventions and assessing a prognosis.
