Well, first of all weight loss would be a great help to all of the issues he has as well as a low salt diet. There is also a
drug called carvedilol (
Coreg) that actually restructures the heart, it doesnt work for everyone but in my case a many others our hearts have returned to normal after having taken the meds for awhile. So have him talk to the Dr.s about that and see what they say. He should also be eligable for cardio rehab, which would be a good place to start for the exercise he needs.
