Bless your heart. All of us are going to face something like this eventually. I'm 78 and my AAA is 4.2 I talked to my cardiologist about the wisdom of having surgery in my 80s. He was as reassuring as he could be. He said new techniques are being developed all the time. By the time I get to 5, there may be a completely new protocol. A lot depends on your health in other respects. The first thing to do is quit smoking. That's the first thing my cardiologist said he tells all his patients. I haven't smoked since I was in my 20s. Do you really want to exhange your life for a cigarette? Get good medical advice, think of your family and friends, be brave. The hardest thing is to be brave, but it's what we all need to do. Good luck. Keep us posted.
