| Outline of Final Research Achievements |
We constructed comprehensive grading system for multicenter evaluation of neointimal coverage (NC) and plaque yellow color (YC) after stent. A total of 264 stents were observed by coronary angioscopy 1 year after PCI. Although the Max-NC grade was similar, the Min-NC grade was significantly higher and heterogeneity index was lower for 2nd-generation DES than for 1st-generation, and similar to BMS. DES. Both the YC grade and the incidence of thrombus with 1st-generation DES were lower than with 2nd-generation DES and BMS. These findings suggest favorable healing process after 2nd-generation DES that is comparable to BMS.
