I am so glad that I am not the one that has to say – who will get the heart. and if it were my love one I would want them to have it. .Morally, I think that you should treat everyone you can. But that's generally not possible, especially with organ transplants. So give the organs to people who need them to survive first, and of them you treat the most likely to survive. Not because that person is more deserving, but because it's more likely to do them good. This should be from a practical and medical sense rather from disapproval of their previous life-style .I do think that the smoker should be given mandatory councelling after the transplant to make them kick the habit.
The number of heart donors has reached a plateau despite an increasing number of potential recipients. More than 5000 cardiac transplants occur each year around the world, although it is estimated that up to 50,000 people are candidates for transplantation [1]. This critical organ shortage means that healthcare providers must strictly evaluate who should receive a heart transplant.
I have read that patients are stratified into low, medium, and high risk of death without transplant. The final decision is listing a patient for transplant is determined by an established cardiac transplant center In who gets a donor heart —and to ensure that donor hearts are distributed fairly, an organization known as UNOS (United Network for Organ Sharing) has created a system.
