I have this disease and have been turned down by vanderbilt and cleveland clinic for stents , but one doctor at another hospital said he could do stent?

Depends: Cardiologists all have different thresholds as to when they should to procedures; even if a procedure can be done doesn't necessarily mean that it _should_ be, if the risks outweigh the benefits. It is always useful to have a second opinion, and the key is to get appropriate informed consent; ask the new doctor why he's willing to do the stent where the others aren't.
