The purpose of this study is to observe the prognosis of 200 patients with long lesions over 30 mm treated with a new-generation Cre8 stent that is polymer-free and releases fat-soluble ampilimus in the real world. In addition, in the case of inserting a 46mm very long stent through sub-analysis, we also want to check whether stent expansion is performed through OCT rather than IVUS.
