Some will die; some won't.  

The only difference is who chooses; a governmental bureaucrat under DMAP in Oregon under Medicaid or an insurance bureaucrat under a different system.

In most instances, I suspect it would make absolutely no difference as to who makes the decision. 

The guy who blew out his lungs using tobacco or the drug abuser who picked up AIDS is not going to get a heart-lung transplant unless he is wealthy enough to pay for it himself.
