Otey,
I had a 72 year old friend at work back in 1990 that went through a very similar situation as you. He was getting tired easily, so he went in and they found 4 blocked arteries, and an anuerysm in his aorta. He had to have open heart surgery first so he could make it through the one later for the anuerysm. He had the heart surgery, then 5 months later they did the second one. He just died recently at the ripe age of 88 years old, and the years in between were healthy and happy. If not for the heart symptoms, he surely would not have gotten a chance at those 17 years. You'll sure be in my prayers.
