What is the life expectancy of a 69 year old male with only 20 percent heart function? In last six years he has had massive stroke (affected left side of body), quadruple bypass, has peripheral arterial disease, COPD, over weight, retains fluid, in and out of congestive heart failure, AFIB, type 2 diabetic and just this week had to have emergency surgery for pacemaker and defibrillator. I know the out look isn't good, just want a general idea as to what to expect.
