interventional cardiology

What would indicate that catherization is desirable?
I have had two emergency catherizations and drug eluting stents were inserted in my RAC and D1. The last time a different brand of stenting was done. I was told that I had restenosis and the new stents were placed inside of the others.
I continue to have pressure pain in my chest and wonder what to do next?

A nuclear stress test would be of value to see if you have an area of lack of blood supply and to help understand your symptoms.
