Abstract

BACKGROUND
The aim of this study was to investigate the impact of ticagrelor monotherapy following 1-month dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) for bifurcation lesions.
METHODS
GLOBAL LEADERS was a randomized, superiority, all-comers trial comparing 1-month DAPT with ticagrelor and aspirin followed by 23-month ticagrelor monotherapy (experimental treatment) with standard 12-month DAPT followed by 12-month aspirin monotherapy (reference treatment) in patients treated with a biolimus A9-eluting stent. The primary endpoint was a composite of all-cause death or new Q-wave myocardial infarction (MI) at 2 years.
RESULTS
Among the 15,845 patients included in this subgroup analysis, 2,498 patients (15.8%) underwent PCI for at least one bifurcation lesion. The incidence of the primary endpoint was similar between the bifurcation and nonbifurcation groups (4.7 vs. 4.0%, p = .083). The experimental treatment had no significant effect on the primary endpoint according to the presence/absence of a bifurcation lesion (bifurcation: hazard ratio [HR]: 0.74, 95% confidence interval [CI]: 0.51-1.07; nonbifurcation: HR: 0.90, 95% CI: 0.76-1.07, p for interaction = .343), but was associated with significant reduction in definite or probable stent thrombosis (p for interaction = .022) and significant excess of stroke (p for interaction = .018) when compared with the reference treatment.
CONCLUSIONS
After PCI for bifurcation lesions using 1-month of DAPT followed by ticagrelor monotherapy for 23 months did not demonstrate explicit benefit regarding all-cause death or new Q-wave MI as in the overall trial.
