Figure 3. Regional maximum principal strain magnitude and angles during LV remodeling.
Maximum principal strain magnitude (E1Mag) is altered in all regions as the ventricle remodels. Infarct (INF) experiences the greatest change in E1Mag, decreasing at 1-wk then increasing at 4-wks. Maximum principal strain angles (E1θRC, E1θRL, E1θCL) where unchanged in the remote region. Infarct and borderzone (BZ) angles rotated away from the radial direction to a more circumferential-longitudinal direction indicating stretch. (+ p<0.05 vs baseline, ‡ p<0.05 vs 1wk, *p<0.05 vs REM, • <0.05 vs BZ)
