 Although drug-eluting stents have reduced rates of restenosis and late lumen loss compared with bare metal stents, late stent thrombosis LST, a life-threatening complication of this technology, has emerged as a major concern. Researches indicated incomplete neointimal coverage of stent struts as the most important morphometric predictor of LST. Pathological research showed stenting disruption of adjacent vulnerable plaques can precipitate LST, Meanwhile, thin-cap fibroatheromas TCFA as the most important predictor of Major Adverse Cardiovascular. Therefore, there is a hypothesis that TCFA may impair intimal healing which are prone to LST in vivo.
