Stent thrombosis (ST) is a catastrophic complication that frequently presents as an acute myocardial infarction and/or death. The most recently accepted definition established by the Academic Research Consortium classifies ST as: early (occurring within 30 days), late (30 days to 1 year) or very late (after 1 year). Very late ST has been reported following drug-eluting stent implantation with rates up to 0.6% per year and has been attributed to delayed strut endothelialization. However, very late ST is unusual after bare-metal stent (BMS) implantation. We report two cases of patients presenting with ST-elevation myocardial infarction due to very late ST 6 and 8 years after BMS implantation.
支架内血栓形成(ST)是一种灾难性并发症,常表现为急性心肌梗死和/或死亡。学术研究联盟最近采用的定义将ST分为:早期(30天内发生)、晚期(30天至1年)或极晚期(1年后)。药物洗脱支架植入术后已报道极晚期ST的发生率高达每年0.6%,并归因于支架小梁内皮化延迟。然而,裸金属支架(BMS)植入术后极晚期ST并不常见。我们报告了2例患者,在BMS植入术后6年和8年因极晚期ST出现ST段抬高型心肌梗死。
