[|Human|] I had 2 stent put in my main heart artery in January.  I am scared to death it may not last. I can find nothing on the internet to give me any hope.  1 artery is fully clogged and the other 2 are badly clogged.I am 73 years old and wonder if a complete by pass is and able to be in my future?
[|AI|]  Hello and thank you for using Chat Doctor. I carefully read your question and I totally understand your concern. It is very difficult to give an opinion just by this short story. But I will try to explain you something. It is quite known in cardiology that stent stenosis might happen. This risk is higher during the first 6 months and then decreases. But there are other possibilities after a stent re-stenosis like angioplasty with balloon, stent-intra stent implantation that mean that you might implant a stent into the obstructed stent, always depending on the type of your first stent and the characteristic of the stenosis. And the last option when the other are not possible is by-pass surgery that you all ready know. So, yes...if your three arteries have problems and your stents get stenosis you might end to bypass surgery. If this is technically possible or not depends on the characteristics of your coronary arteries and the positions of stenosis. The risk of bypass surgery depends on your age, your heart function and other organs functions. But you should not worry. You do have possibilities to go quite well. There are a lot of possibilities today with a good chronic medical treatment, angioplasty and by pas' surgery. Wish I was helpful. Best regards.
