• Note (General): type:Thesis; Background:The association between unfavorable post-stent optical coherence tomography (OCT) findings and subsequent stent thrombosis (ST) remains unclear. This study investigated the ST-related characteristics of post-stent OCT findings at index percutaneous coronary intervention (PCI).Methods and Results:Fifteen patients with ST onset after OCT-guided PCI (ST group) were retrospectively enrolled. Post-stent OCT findings in the ST group were compared with those in 70 consecutive patients (reference group) without acute coronary syndrome onset for at least 5 years after OCT-guided PCI. The incidence of acute myocardial infarction (AMI) was higher in the ST than reference group (60.0% vs. 17.1%, respectively; P=0.0005). The incidence of incomplete stent apposition (93.3% vs. 55.7%; P=0.0064), irregular protrusion (IP; 93.3% vs. 62.8%; P=0.0214), and thrombus (93.3% vs. 51.4%; P=0.0028) was significantly higher in the ST than reference group. The maximum median (interquartile range) IP arc was significantly larger in the ST than reference group (265° [217°–360°] vs. 128° [81.4°–212°], respectively; P<0.0001). In AMI patients, the incidence of a maximum IP arc >180° was significantly higher in the ST than reference group (100% vs. 58.3%, respectively; P=0.0265).Conclusions:IP with a large arc was a significant feature on post-stent OCT in patients with ST.; 博士（医学）・甲第868号・令和5年3月15日; © 2021, THE JAPANESE CIRCULATION SOCIETYThis article is licensed under a Creative Commons [Attribution-NonCommercial-NoDerivatives 4.0 International] license.; identifier:Circulation journal Vol.85 No.6 p.857-866 (2021 May); identifier:13469843; identifier:http://ginmu.naramed-u.ac.jp/dspace/handle/10564/4100; identifier:Circulation journal, 85(6): 857-866
