Figure 1 The percentage of patients with a normal and abnormal stress echocardiogram with normal or abnormal (ischemic, fixed, or mixed) wall motion for each category of left atrial volume index (LAVI). None of the patients with LAVI 28 ml/m2 had a positive stress echocardiogram (i.e., new wall motion abnormality), but three had a fixed wall motion abnormality localized to the inferior wall.

Figure 2 Mean ± SD left atrial volume index (LAVI) according to different wall motion abnormality (WMA) results. Left atrial volume index is significantly different between normal and any WMA (new, fixed, or mixed). An atrial volume >28 ml/m2 is associated with escalating cardiovascular risk, including risk of ischemic heart disease.
