摘要Although the incidence of coronary stent fracture (SF)is relatively rare,the increasing amount of patients undergoing percutaneous coronary intervention (PC1)indicates more cases of SF.The incidence of sirolimus-eluting stent (SES) fracture is reported in 0.89％ to 4.4％ of patients at 6 to 12 months follow-up angiography post-PCl.1,2 Recently,SF has been recognized as a complication that may result in thrombosis,perforation,restenosis,and migration of the stent resulting in morbidity and mortality.Here we describe a rare case presented with ST-elevation myocardial infarction (STEMI),which was caused by very late stent thrombosis due to SES fracture,in order to help the physicians ensure rapid recognition and treatment of this urgent situation.
