Hello. Welcome to HCM and thank you for your question. I understand your concern.
Stent occlusion (total blockage) and intra-stent stenosis (narrowing within the implanted stent) are two very well-known situations. The highest probability of the latter to happen occurs within 6 or 12 months after
implantation, depending whether it is a bare metal stent or a drug eluting stent. A stent found patent 10 years after implantation has a very low, negligable probability of blocking. The treadmill, back in 2010, was mildly positive, probably because of the new stenoses that were developed in your coronary arteries, throughout years. The therapy looks fine and appropriate to me. If the symptoms, such as
angina,
shortness of breath,
fatigue, develop, then this means that the new stenoses, not found on 2000, have made progress and narrowed the coronary arteries further more. If this is the case, you should consult your cardiologist about having another coronary angiogram and the possibility of another stent in another
artery which is producing the symptoms. If you do are symptom-free, then adhere to your therapy and a cardiac
stress test twice a year is a reasonable approach.
I hope I was of help. Take care.
Kind regards,
Dr. Meriton
