Documented subacute stent thrombosis within thirty days after stenting with sirolimus-eluting stent (Cypher®) for acute myocardial infarction -: A Japanese single center retrospective non-randomized study

Background The incidence of subacute stent thrombosis (SAT) within 30 days after stenting with a sirolimuseluting stent (Cypher (R)) for acute myocardial infarction (AMI) was retrospectively compared to that with bare-metal stents (BMS). Methods and Results Among 559 lesions in 558 consecutive AMI from April 2003 to February 2006, the incidence of documented SAT after Cypher (R) implantation (2/276 lesions, 0.72%) was almost the same as for BMS (2 cases, 0.71 %). Aspirin (81-100 mg/day) plus ticlopidine (200 mg/day) were administered continuously after admission in all 4 cases. Conclusion Documented SAT did not increase after stenting with Cypher (R) for AMI under aspirin plus ticlopidine.
