Coronary stents have been improved in materials, design, coating and antiproliferative drugs in many aspects, but at present, coronary stents still have long-term chronic inflammatory reaction and new atherosclerosis, leading to coronary vasomotor dysfunction, thrombosis and restenosis. In order to address the limitations of current coronary stents, the latest preclinical and clinical studies have evaluated the feasibility of novel bioabsorbable metal stents, including novel bioabsorbable alloys and novel bioabsorbable metal coatings. The purpose of this article is to summarize the latest research results on coronary bioabsorbable metal stents and provide a reference for the clinical application.
