Figure 1 The change in left ventricular volume indexes between baseline and five months of follow-up measured with magnetic resonance imaging (MRI). The mean ejection fraction remained unchanged, but end-systolic and end-diastolic volume index decreased significantly.

Figure 2 Improvement in end-systolic volume index (ESVI) and ejection fraction (EF) was related to the extent of dysfunctional but viable myocardium before revascularization. No relationship was found for end-diastolic volume index (EDVI).

Figure 3 Improvement in segmental wall thickening (SWT) was related to the transmural extent of infarction assessed with magnetic resonance imaging (MRI) before revascularization. Solid bars = before revascularization; open bars = five months after revascularization.
