REPRODUCIBILITY OF WALL-MOTION SCORE AND ITS CORRELATION WITH LEFT-VENTRICULAR EJECTION FRACTION IN PATIENTS WITH ACUTE MYOCARDIAL-INFARCTION

The inter- and intraobserver variability, as well as the relation to l eft ventricular (LV) function indexes, of LV wall motion score calcula ted using the 16- and 11-segment models of LV segmentation were assess ed in 105 patients with acute myocardial infarction who were examined at 36 +/- 7 hours from onset of symptoms. In these patients, the use o f the 16-segment model of LV segmentation portends to a significantly higher inter- and intraobserver reproducibility of segmental wall moti on score than the use of the 11-segment model, In addition, wall motio n score assessed with the more detailed 16-segment model of LV segment ation showed a significantly higher correlation with LV ejection fract ion than the wall motion score assessed using the 11-segment model.
