Hello everyone, I suffered a heart attack a number of years ago. I had 3 stents and ultimately had open heart. I felt great for about 3 years and starting going down hill eversince. I have the same symtoms as before the open heart. I went for a cardiac cath (dye test) yesterday to see what the problem was. Turns out the by pass is in great shape but the blood flow is not using it. It is still trying to use the artery that was by-passed. That artery is closed 75%. My question is:

According to my doctor the is only treat with an increase in meds.

Has anyone ever heard of this?
