Abnormalities of regional systolic function are important complications of acute or chronic coronary artery disease. The extent and severity of these abnormalities are powerful predictors of subsequent clinical course.'-3 By virtue of its noninvasive nature, safety, portability, and ease of repetition, two-dimensional echocardiography (2DE) is, in theory, an ideal technique for studying systolic function following acute MI. Several studies have confirmed that qualitative analysis of 2D echocardiograms can identify regional contraction abn~rmalitiesl-~ and when used in a semiquantitative manner by experienced observers, provides important short-term prognostic information in patients with acute MI.'-396 In those surviving the acute phase of the infarction, predischarge semiquantitative 2DE predicts oneto two-year outcomes as Division of the LV into standardized segments," standard nomenclature for degree of asynergy," and other conventions promote a unified approach and allow interstudy comparisons. In general, when newer 2DE equipment is used, reproducibility of qualitative review of echocardiograms for identifying regional wall motion abnormalities (RWMA)'r5v6 compares favorably with previously reported results with qualitative angiography.'2*13 But qualitative and semiquantitative wall motion analyses are inferior to quantitative methods because of poorer reproducibility of results even when trained observers are used.".'3 Identifying diography.
