Abstract:
BACKGROUND:Antiplatelet therapy is required after drug-eluting stent (DES) implantation, but bleeding events occur unexpectedly. We aimed to assess whether bleeding event predictors after 2nd generation DES (2nd DES) implantation differed by time after implantation. METHODS:We studied 1912 consecutive patients who underwent successful 2nd DES implantation (70±10 years, 72% male). Bleeding events were recorded as early (≤1 year) and late (>1 year). Major bleeding events were defined as a composite of type 5, 3, and 2 bleeding in the Bleeding Academic Research Consortium criteria. Predictors were assessed using a Cox proportional hazard model. RESULTS:Bleeding event rates were 3.3%, 5.1%, and 6.7% at 1, 2, and 3 years, respectively, with the highest 1-year rate in year 1 (p<0.001). Cause and severity of bleeding events were similar between early and late bleeding events. Prior history of gastrointestinal bleeding, non-steroidal anti-inflammatory drug use, and triple antithrombotic therapy [adjusted risk ratio (RR): 3.68, 3.21, 4.57, respectively; p<0.01] were independent predictors of early bleeding events. Age >80 years and severe renal dysfunction (adjusted RR: 2.27, 2.02, respectively; p<0.01) were independent predictors of late bleeding events. Survival rate was significantly lower in patients with bleeding events compared with patients without bleeding events (82.4% vs 90.1%; p<0.001). CONCLUSION:Frequency and predictors of bleeding events after 2nd DES implantation differ by time after implantation. Treatment strategies corresponding to individual patients are required.
