The aim of this study was to evaluate the frequency, predictors and the clinical outcome of stent thrombosis after DES implantation and bare metal stent (BMS) implantation in Asian races.
A total of 14,577 consecutive patients who underwent successful DES implantation (8,809 patients, 62% of the lesion with Sirolimus–eluting stent: SES, 38% of the lesion with Paclitaxel–eluting stent: PES) and BMS implantation (5,768 patients) were included in this study. We evaluate the frequency, predictor of stent thrombosis.
At a mean follow–up of 78.5±29.9 months in DES and 81.8±26.4 months in BMS. The cumulative incidence of stent thrombosis were subacute stent thrombosis (SAT): 0.5% with DES and 0.6% with BMS, late stent thrombosis (LAST): 0.18% with DES and 0.1% with BMS, very late stent thrombosis (VLAST): 0.18% per year with DES and no BMS. Independent predictors of stent thrombosis are bifurcation lesion (OR=1.90, 95% CI: 1.83 to 24.24, p=0.01) and ejection fraction (OR=0.90, 95% CI: 0.86 to 0.94, p=0.03). Only 0.2 % of the patients were died because of the myocardial infarction after stent thrombosis in both groups.
The incidence of stent thrombosis in Asian races is relatively low (0.5 % with DES and 0.6% with BMS of SAT, 0.18% increase per year with DES of late stent thrombosis) at mean follow–up to 7 years. Particular attention will need to be directed to this complication when the patients have bifurcation lesions or low ejection fraction.
