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.
