Wow, I am so sorry to read of your outcome from the bypass and I am sure you are very anxious right now but I think you have a right to be.
When clogged plaque narrows an artery that feeds the heart, the body responds by trying to bulk up tiny blood vessels in the heart. As these so-called collateral vessels grow more muscular and interconnected, they begin to reroute some of the blood flow around the blockage.
I think the good news is that 2 of the grafts worked well and the stents are in place on the 2 that failed. I know this may soaund trite but take things easy, and try not to get frustrated.
My prayers go out to you as my sister had bypass surgery at 78 years old.
