2.5. Study Outcomes
acute gain, restenosis, MLD
ACUTE MYOCARDIAL INFARCTION, CARDIAC DEATH, SECONDARY, MLD, CARDIAC EVENTS, RESTENOSIS
The primary outcome was late lumen loss (LLL) of the MV and SB. The secondary outcomes were minimum lumen diameter (MLD) and acute gain and restenosis. In this study, we divided the SB into two parts for separate analysis. These parts were the “ostium,” which is about 3–5 mm from the beginning of the SB and the “shaft,” which is about 3–5 mm away from the ostium part. In terms of in-hospital and long-term clinical outcomes; we focused on major adverse cardiac events (MACEs: acute myocardial infarction, cardiac death, target vessel revascularization).
