[|Human|] My father was just rejected for kidney transplant as he is diabetic and on dialysis. The rejection was due to his heart being too weak at 35 percent function; he had congestive heart failure last year. He is 78 years old, but seems strong to me. What would be average expectations?
[|AI|]  Hello, for a person to undergo renal transplant, they patient should be fit for the surgery to undergo. For that his diabetes should be well controlled, if hypertension is there then the BP should be well controlled. As for his heart condition where you specified his EF is only 35%, it is quite low. In surgery some time bleeding can occur in which state the patient undergoing surgery should have a heart strong enough to handle the blood loss and decreasing volume. As your fathers EF is only 35%, his heart won't be in condition to handle any situation occurring during surgery. So even if he appears to be fit to you, seeing his heart condition it will be inadvisable for him to undergo the transplant.
