[Acute myocardial infarction due to late stent thrombosis seventeen months after stent implantation: a case report].
A 59-year-old man with acute myocardial infarction underwent successful stent implantation for proximal left anterior descending coronary artery occlusion. Antiplatelet therapy with 100 mg aspirin/day and 200 mg cilostazol/day was started after stenting and continued for 4 weeks. There was no cardiac event during the 1 year follow-up period. Follow-up coronary angiography at 12 months after stenting revealed no in-stent restenosis. The patient was admitted 17 months later due to sudden onset of severe chest pain. Electrocardiography revealed ST segment elevation in leads V1-V4. Emergency coronary angiography disclosed obstruction of the proximal left anterior descending coronary artery with thrombus. Intracoronary aspiration thrombectomy was successful. We describe a patient with acute myocardial infarction who had late stent thrombosis 17 months after stent implantation.
