OBJECTIVES: This study sought to evaluate the incidence of @entity397 ( @entity397 ), @entity2681 ( @entity2681 ), and calcified nodule (CN) using optical coherence tomography (OCT) in @entity1 with @entity583 ( @entity583 ); to compare detailed morphologic plaque characteristics of @entity397 , @entity2681 , and CN with optical coherence tomography and intravascular ultrasound; and to compare the post-procedure outcomes among @entity397 , @entity2681 , and CN. BACKGROUND: The incidence and detailed morphologic characteristics of @entity397 , @entity2681 , and CN in @entity583 @entity1 and their outcome after percutaneous coronary intervention (PCI) are unknown. METHODS: A total of 112 @entity583 @entity1 who underwent PCI within 12 h from symptom onset were included. Both optical coherence tomography and intravascular ultrasound were performed following aspiration thrombectomy. RESULTS: The incidence of @entity397 , @entity2681 , and CN was 64.3%, 26.8%, and 8.0%, respectively. @entity2681 and CN, compared with @entity397 , had more @entity82 (p  < 0.001 and p  < 0.001) and less thin-cap @entity1856 (p  < 0.001 and p  < 0.001) as well as smaller plaque burden (p  = 0.003 and p  = 0.001) and remodeling index (p  = 0.003 and p  < 0.001). @entity2681 had greater plaque eccentricity index than @entity397 and CN (p  < 0.001 and p  < 0.001). CN had greater calcified arc and shallower @entity460 than @entity397 (p  < 0.001 and p  < 0.001) or @entity2681 (p  < 0.001 and p  < 0.001). More than one-half of CN had negative remodeling. @entity2681 had a lower incidence of no-reflow phenomenon after PCI than @entity397 (p  = 0.011). CONCLUSIONS: @entity2681 was the underlying mechanism in one-fourth of @entity583 . @entity2681 was characterized by @entity82 . CN was characterized by superficial large @entity460 and negative remodeling. @entity2681 was associated with less @entity16 after PCI.
