My father has had a heart attack.  When the doctoc came in he told us only 20% of his heart is functioning normally.  50% of his heart was severely damaged by the heart atttack.  They have done several test on his heart.  A heart Cath which showed blockages all over, a nuclear dye test to show viability of the remaining heart muscle. One doctor has told him he is not a candidate for surgery.  He is seeking a second opinion today.  Can you help me with some questions to ask this new doctor?
Viability test is the correct approach. If there is negative viability test then their is no is for surgery. It will not benefit him.
