Results
In patients with signs of viable myocardium (group 1) volume of perfusion defect was substantially smaller than in patients with nonviable myocardium (groups 2 and 3): 1 cm3 (0.4—2.4) vs.
7.3 cm3 (5.3—10.0) and 6.3 cm3(5.0—15.0),
respectively,
p<0.001 (table 1).
LVESV and LVEDV were significantly higher and the EF is lower In the Group 1 than in the other Groups (table 1).
Patients of Group 1 more often were female (p=0.04),
had inferior MI (p<0.001),
and spontaneous reperfusion (p<0.001) compared with Groups 2 and 3.
During the 12-month period LVEDV significantly decreased in Group 1 and increased in Group 2,
LVESV significantly decreased in Group 1 and increased in Groups 2 and 3,
LV EF significantly increased in Group 1, but there was no significant increase in Groups 2 and 3 (Figure 4-6).
After 12 months LV remodeling was registered in 19.3% of patients (fig.4),
all had signs of nonviable myocardium in >3 LV segments.
In patients with perfusion defect ≥10 cm3 probability of development of LV remodeling exceeded 50%.
