Reproducibility of wall motion score and its correlation with left ventricular ejection fraction in patients with acute myocardial infarction

Am J Cardiol. 1996 Oct 1;78(7):855-8. doi: 10.1016/s0002-9149(96)00440-7.


The inter- and intraobserver variability, as well as the relation to left ventricular (LV) function indexes, of LV wall motion score calculated using the 16- and 11-segment models of LV segmentation were assessed in 105 patients with acute myocardial infarction who were examined at 36 +/- 7 hours from onset of symptoms. In these patients, the use of the 16-segment model of LV segmentation portends to a significantly higher inter- and intraobserver reproducibility of segmental wall motion score than the use of the 11-segment model. In addition, wall motion score assessed with the more detailed 16-segment model of LV segmentation showed a significantly higher correlation with LV ejection fraction than the wall motion score assessed using the 11-segment model.
