to delineate the relative effects on left ventricular function of the site , extent and nature of the abnormal left ventricular segmental contraction ( dyssynergy ) and thereby determine the mechanism by which anterior myocardial infarction results in greater depression of left ventricular performance than does inferior infarction , 43 patients with remote myocardial infarction of similar extent ( average 38 percent of left ventricular systolic perimeter ) and associated hypokinesia or dyskinesia confined to either the anterior or inferior wall were compared ;
