I don't want to be overly mean, but just look at the statistics. Those cases are far and few between. I have myself CPRed more than 50 people in my previous career. For all I know not a single one was able to walk out of the hospital - and the majority was declared dead on the scene.
YMMV based mainly on country (and hence willingness / ability of the general population to deliver quality CPR)
In most cases, when the patient "survives" this means that he is disabled (can not eat, can not walk, can not stand, can not do anything)
