Can the artery close after a stent is placed?

There's always a risk that narrowing can recur with heart disease; blockages can occur even with a stent. Regular metal stents have a drug coating that helps reduce the risk for another blockage, specifically over the first one to two years. Usually the narrowing that recurs in a stent is not from cholesterol plaque buildup, but from tissue growth that occurs because of the inflammation created by putting in a metal stent.
