Despite having MVO, IMH was absent in ten patients in our study. We postulate that, for some patients in the MVO(+)/IMH(−) group, the ischaemic threshold for IMH may not have been reached yet. This could explain the discrepancy between the predicted IMH values and the negative findings at CMR. Lending support to this concept was the finding that all measured parameters, including MVO size, were in between the average values of the two other groups. It is therefore likely that the groups reflect a gradation of the severity of ischaemic damage.
