Thanks everyone for sharing your experiences and your encouraging words.
To answer some questions, I was under treatment for high blood pressure and lipids for probably the last 20-25 years. They were under control with medication. Also I was at a good weight(150). I started regular aerobic exercise about 10 years ago with jogging and, later, cycling. I was feeling very fit - no chest pain, no shortness of breath. However, I was a smoker up to about the age of 40 and probably not that active.
The heart attack was totally unexpected. I was out for a planned 30 mile ride, something I did several times a month. At first I though maybe I was pushing a little too hard getting chest pains and breathless and all, but I had all of the classic symptoms.
I don't yet know the specifics of the damage. I guess I was hoping I'd be closer to where I was before the attack. The stress test was a bit of a shocker.
Although I feel pretty good physically, I do have a lot of anxiety. I'm no stranger to that but it is there and something I need to deal with to feel better.
Again, thank you all for your comments.
