Duration of dual antiplatelet therapy after drug-eluting stent implantation is still an important issue awaiting a definite answer. A 50-year-old male patient was admitted with acute-onset chest pain and was diagnosed to have acute anterior myocardial infarction due to very late stent thrombosis. He had a 38-month history of two sirolimus-eluting stent implantation in the proximal left anterior descending (LAD) coronary artery. He had been on warfarin along with clopidogrel 75 mg/day until he decided to cease clopidogrel before a minor dental procedure 10 days before. Findings of physical examination and laboratory tests were normal except for an INR value of 4.4. After a loading dose of 300 mg clopidogrel, he was immediately taken to the catheterization laboratory. Angiography of the left system showed total occlusion of the proximal LAD with a thrombus at the level of the proximal stent. He was successfully revascularized without any complication and was discharged free of symptoms.
