Hi Barb! Sorry it took me so long to get back to you...
Here's a link for you or others that want more info on Toprol~it can cause some memory problems.

If you have an arterial blockage anywhere it would show up, even where the stent was placed, as a very limited amount of blood flow passing through the area. Sometimes further testing such as doing a heart cath is the best way "the gold standard test" to tell if they have any questions remaining re any blockages.
I'm feeling better, Barb, I hope you are, too!!
Hugs, Teri
