I can only answer the original question from an atheist's point of view by saying that when faced with impending death, I was willing to accept assistance from whatever sources presented an opportunity. For me this included welcoming prayers on my behalf by well-meaning persons of faith.
Therefore, I must assume that creationists and others who do not "believe" in science, stem cell research, etc., might welcome the unbridled application of such medical benefits as are available them in the face of death (the Great Equalizer).
Besides, I think it would be immoral to withhold the benefits of medical science from a patient simply based upon that patient's previously stated beliefs which in many cases are a lot of blarny in the first place.
