My husband has had atherosclerotic heart disease and PAD for 28 years. He has lost a leg, and had triple bi pass, need quad but not parts, two blocked again.  He has great pain when walking very short distance in both legs.  Has had two strokes.  He looks ashen. Cardiologist wants us to see 3 different dr. to treat, sleep apnea, legs, and dizziness. Kidney function 50% No one will give me a straight answer on life expectancy, what to expect. No one dr. treats whole disease. Help
No one will give you a straight answer because there isn't one. When you add up the problems described an expected survival might be quite short. On the other hand, you would have gotten the same answer 28 years ago when his problem was first discovered. When problems become multiple and complex, our guesses get too fuzzy to give you an honest answer. Your cardiologists' advice seems quite sound. Even treating sleep apnea. It seems so minor but may have a profound impact.
