[|Human|] I have question regarding a stent which was put in 10 years ago. What is the best way to detect if the stent is still working properly. My doctor has ordered a Stress Test, but said the large medical centers might have a better way of detecting this. My blood pressure is normal, but I have felt a little pressure in my chest. Of course, this pressure could be the result of a pulled muscle, but I don t know how to know the exact cause. The pressure is not a problem at this moment. Thanks so much for your help! HGE
[|AI|]  Hi, Coronary angiography would be the gold standard. However, by angiography, the incidence of restenosis is significantly higher than clinical restenosis because many patients have mild restenosis that does not result in a recurrence of symptoms. Coronary CT angiography (CTA) with dose modulation is a non-invasive alternative. Hope I have answered your query. Let me know if I can assist you further.
