It is generally accepted within the medical community to stop Plavix after about a year after a DES implant. DES may be more vulnerable to clots than bare metal?! It is not necessary to be weaned off Plavix; I and many others have abruptly stopped without side effects. I continue with a baby aspirin daily for CAD.
There is a risk/benefit for the blood medication, and the doctor is in the best position to know and evaluate the risk of bleeding with the upcoming intervention...I believe diabetes is a major factor in any decision. We have to trust our doctors, if not worthy of trust change doctors. You should be alright so don't worry.
