I had a stint put in my LAD and within 6 months I fail the stress test. The doctor had me in the hospital for another ango. They thought the unthinkable, that my stint failed. Or my stint was block, and maybe having to put another one in behind it might help me.
When it was over I ask the doctor what did they find. They told me nothing. So I think that going back in might of help whatever the problem could of been resoved it self. I never really knew why?
So some doctors do believe sometimes that a stint might be bad. Just how many I don't know?
