IMHO I would go ahead and take care of the colonoscopy. You don't want any polyps (if any) to become the bad type. I was taking statins + baby aspirin. Went for an angiogram since my LAD shows signs of blockage through the PET scan. Yes, I have 60%-70% block in its mid section and decided NO on the stent, just very aggressive health care management from now on. Two days later after the procedure I developed a blood clot in my vein (not artery) which was not caused by the catheterization but for the way the nurse put the patch on my leg (a lot of pressure so it burst if that makes sense). Now I am on blood thinners (Eliquis) so it "melts away" the vein blood clot for 90 days. I need to have my colonoscopy done as well and will have to stop the blood thinners 5 days before the colon procedure. Cardiologist will have to give be the green light for that because of possible internal bleeding (reason why on my next appointment the cardiologist is going to have to convince me that baby aspirin is absolutely necessary).
I am asymptomatic.
