Double jeopardy: balance between bleeding and stent thrombosis with prolonged dual antiplatelet therapy after drug-eluting stent implantation.

Prolonged dual antiplatelet therapy with aspirin and clopidogrel is mandatory after drug-eluting stent (DES) implantation because of potential increase risk of stent thrombosis compared to bare-metal stents. As more DES are being implanted, many of these patients will undergo non-cardiac surgery whilst on antiplatelet therapy. The optimal management of perioperative antiplatelet therapy is not well established. The risk of excessive bleeding associated with antiplatelet therapy needs to be balanced against the risk of stent thrombosis with interruption of antiplatelet therapy on a case-to-case basis.
