从尸检病例中取出植入时间>30天的人冠状动脉裸金属支架(BMS)和药物洗脱支架(DES),检查是否存在新生内膜动脉粥样硬化疾病。BMS植入后新生内膜动脉粥样硬化变化(新动脉粥样硬化)很少报告,通常发生在5年后。DES植入后新动脉粥样硬化的发生率尚未报道。检查了CVPath支架登记研究中所有可用病例(n=299例尸检),共包括406处病变(197例BMS,209例DES [103例西罗莫司洗脱支架(SES)和106例紫杉醇洗脱支架(PES)]),植入时间>30天。新生动脉粥样硬化被认为是新生内膜内充满脂质的泡沫状巨噬细胞簇,有或没有坏死核心形成。DES组的新动脉粥样硬化发生率(31%)显著高于BMS组(16%)(p<0.001)。DES中出现新动脉粥样硬化的支架植入时间中位数短于BMS(DES:420 [361-683]天,BMS:2160 [1800-2880]天,p<0.001)。以薄帽纤维粥样硬化或斑块破裂为特征的不稳定病变在BMS(n=7,4%)中的发生率高于DES(n=3,1%)(p=0.17),DES的植入持续时间(1.5±0.4年)相对短于BMS(6.1±1.5年)。通过多元逻辑回归确定的新动脉粥样硬化的独立决定因素包括年龄较小(p<0.001)、植入持续时间较长(p<0.001)、SES使用(p<0.001)、PES使用(p=0.001)和基础不稳定斑块(p=0.004)。新动脉粥样硬化在DES中是常见的发现,并且发生早于BMS。BMS和DES的新动脉粥样硬化的不稳定特征均被确定,后者的植入持续时间较短。新动脉粥样硬化的发展可能是另一种罕见的晚期血栓形成事件的促成因素。
Human coronary bare metal stents (BMS) and drug-eluting stents (DES) from autopsy cases with implant durations >30 days were examined for the presence of neointimal atherosclerotic disease. Neointimal atherosclerotic change (neoatherosclerosis) following BMS implantation is rarely reported and usually occurs beyond 5 years. The incidence of neoatherosclerosis following DES implantation has not been reported. All available cases from the CVPath stent registry (n=299 autopsies), which includes a total of 406 lesions (197 BMS, 209 DES [103 sirolimus-eluting stents (SES), and 106 paclitaxel-eluting stents (PES)]) with implant duration >30 days were examined. Neoatherosclerosis was recognized as clusters of lipid-laden foamy macrophages within the neointima with or without necrotic core formation. The incidence of neoatherosclerosis was significantly greater in DES (31%) than BMS (16%) lesions (p<0.001). The median stent duration with neoatherosclerosis was shorter in DES than BMS (DES; 420 [361–683], BMS; 2160 [1800–2880] days, p<0.001). Unstable lesions characterized as thin-cap fibroatheromas or plaque rupture were more frequent in BMS (n=7, 4%) than DES (n=3, 1%) (p=0.17), with relatively shorter implant durations for DES (1.5±0.4 years) compared to BMS (6.1±1.5 years). Independent determinants of neoatherosclerosis identified by multiple logistic regression included younger age (p<0.001), longer implant durations (p<0.001), SES usage (p<0.001), PES usage (p=0.001), and underlying unstable plaques (p=0.004). Neoatherosclerosis is a frequent finding in DES and occurs earlier than in BMS. Unstable features of neoatherosclerosis are identified for both BMS and DES with shorter implant durations for the latter. The development of neoatherosclerosis may be yet another rare contributing factor to late thrombotic events.
