I'm not sure exactly what it is that you're asking. I'm sure there are many people that have had very good results with stents. Unfortunately, I ain't one of them. I had 3 stents installed in 2-03. By mid May, all 3 were blocked 90% or more, so I had triple bypass surgery. In July and August, 2 of the 3 bypass grafts were starting to block, so they installed stents in them. Since then, I've had no problems. The first 3 stents were of the unmedicated kind, and the last 2 were drug eluting. If you got the coated stents, it ups the chance for success quite a bit. I think the restenosis rate goes from about 30% for plain stents to about 5% for the medicated ones.
All you can do is control what factors you can (diet, drugs, exercise, smoking, etc), and hope for the best. Gotta figure there's a pretty good chance that you'll be in the 95% with no problems.
I really don't know how representative my case is among all heart events. I'm pretty convinced that I was not treated correctly from the get-go. Seems to me that stenting originally probably was an overreaction. Should have been drugs and lifestyle changes and see how it goes. Bypass may still have been needed, but maybe not. Even when the original 3 stents blocked, there was no attempt to clear them--just bypass surgery. We'll never know I guess. I just hate to use up the treatment of last resort before getting to the point of last resort.
Hope everything goes well for you. Try to not worry too much about it. If something does need a redo or something, you'll know it. Symptoms should be very similar to what you had before. Don't take chances with it though--if you think you got a problem, get help. Don't put it off.
I guess I haven't brightened your day too much, huh?? Just don't be overly concerned about the stents. At least not until you have something to be concerned about--you'll probably be good as new for a long, long time.
