When can I start exercising again after an angioplasty for blood vessel blockage?

1-2 weeks. The main reason for delaying exercise is to permit the groin to heal. The procedure usually inserts a needle and catheter through an artery in the groin. After removing the catheter, if the artery is not sealed completely, exercise with a lot of groin bending may start bleeding from the artery that had been entered. It doesn't happen often, but when it does surgical repair might be needed.
