Ischemia because defeicency of nutrients

Hypoxia is inadequate oxygen supply at the cellular (or, better, mitochondrial) level. By contrast, ischaemia is a lack of blood supply to a cell/tissue/organ/etc. Let’s assume, for simplicity, that patient A’s cells are exposed to total hypoxia (i.e. anoxia - absolutely no oxygen), whereas patient B’s cells are exposed to total ischaemia. Which is worse?
As it turns out, patient B is in considerably more trouble, all other things being equal.
