My husband recently survived a heart attack - 99% blockage in the widowmaker. The medical experts say it s a miracle he survived. His MRI is fine, but his heart pumping rate is 32, and 50 is good number. This is 3 months after the tragic event. His doctor says that 25-30% of his heart is dead. Will he ever resume normal activites - work, etc. He seems to be tired all of the time. His primary goal is to return to work which is a very physically demanding job with long hours. Will that happen?
