- FIGURE 1.
99mTc-MIBI SPECT and FDG PET images of patient with MI. (A) Perfusion–metabolism MM at apex, anterior, septal, and inferoposterior walls (arrows) before revascularization. (B) After CABG, perfusion defects of segments improved significantly and size of left ventricle decreased. EF increased from 30% to 42%. ST = stress; RE = rest.

99mTc-MIBI SPECT (A) and FDG PET (B) images of patient with MI show perfusion–metabolism M in inferoposterior wall (arrows) before revascularization. (C) After CABG, perfusion defects did not improve and EF did not change (38% vs. 39%).

Changes of EF (%) and EDD (mm) at baseline (Pre), 3 mo (Pos1), and 6 mo (Pos2) after revascularization in groups A1 and B1.

Cumulative cardiac event-free survival curves of groups A1 and A2 (A) and groups B1 and B2 (B). RVS = revascularization; Med = medical therapy.
