Predictors of target lesion revascularization and documented stent thrombosis beyond 30 days after sirolimus-eluting stent implantation: retrospective analysis in consecutive 1,070 angiographic follow-up lesions.

Background: Outcomes after sirolimus-eluting stent (SES: Cypher) implantation remained to be elucidated in Japan.

Methods And Results: Among 1,070 consecutive angiographic follow-up lesions, 99 lesions underwent target lesion revascularization (TLR) with in-stent restenosis (ISR). Retrospective estimation by multivariate analysis including 50 variables showed that the ostiums of right coronary and left circumflex arteries, hemodialysis, calcification, non-direct stenting, ISR of SES, and non-eccentric lesion were the predictors of TLR.
