How serious is the risk of blood clots?

I think the biggest misconception is that when a stent is put in, that’s it’s going to clog up. Absolutely not true, that when a stent is put in that you have this really large risk of a problem. It turns out that it’s really only about 1 or 2 out of 100 patients that have a risk of clots, that if you take your medicine, the Clopidigril and the aspirin, you actually have a very low chance of that happening.
