Soon after MI (day 1 post-MI), PO and LRT rabbit hearts tend to fail during ex vivo inflation testing at similar rates in similar locations, primarily the infarct core and the borderzone. By day 3 post-MI, LRT hearts have gained an improved resistance to failure and failure did not occur in the infarct or borderzone regions. Conversely, PO samples exhibited the largest rate of rupture in the understudied borderzone. Circles corresponding to the infarct, border, and elsewhere in the heart are not drawn to scale. Data replotted from Connelly et al. (1992)
