How fantastic that you discovered the blockage and had it corrected - and a year later - look at you! This has made my day. I was on a ride in the Napa Valley in August and a friend of mine was on a tandem with her husband. Long story short, we came upon an ambulance - and it was my friend's husband. He had a heart attack on the road. Lucky for him, a cardiac surgeon was riding behind them and also a nurse - they revived him with CPR after 25 - 35 minutes of working. A helicopter was brought in and he had 2 more heart attacks before reaching the hospital. He had major blockage and wasn't aware of it. He was released from the hospital 4 days later and was walking the neighborhood within a weeks time. So hooray for medical advancement and good luck with your continued progress. Bekki
