<s>[INST] i had a heart attack at 37 years old, 40years old and have atleast 6 stints in my heart,. i again have been having chest pain. i just went for a nuclear stess test on tuesday. am i at high risk of needing a bypass soon? i am very scared [/INST] Hello, First, there is a need of getting an Angiography done to evaluate that all the stents are patent or not. If they are patent then things can be evaluated on a regular basis and if they are getting occluded then treatment will be on urgent basis.  The bypass will be required or not that can be decided only after Angiography results. Hope I have answered your query. Let me know if I can assist you further.  </s>
