Thanks for your question
Well which nuclear test did you get?
Anyways you need an angiography
done to directly observe the stents and coronaries.
If there is any significant restenosis
, you can get another stent placed over the site with drug eluting stent.
However, management for coronary artery
disease if highly individualized therefore you need to discuss the options with your cardiologist
Hope that answers your question
Keep in touch
