Abstract
Abstract Aims This subgroup analysis of the ENTRUST-AF PCI trial (ClinicalTrials.gov Identifier: NCT02866175; Date of registration: August 2016) evaluated type of AF, and CHA 2 DS 2 -VASc score parameters as predictors for clinical outcome. Methods Patients were randomly assigned after percutaneous coronary intervention (PCI) to either edoxaban (60 mg/30 mg once daily [OD]; n = 751) plus a P2Y 12 inhibitor for 12 months or a vitamin K antagonist [VKA] ( n = 755) plus a P2Y 12 inhibitor and aspirin (100 mg OD, for 1–12 months). The primary outcome was a composite of major/clinically relevant non-major bleeding (CRNM) within 12 months. The composite efficacy endpoint consisted of cardiovascular death, stroke, systemic embolic events, myocardial infarction (MI), and definite stent thrombosis. Results Major/CRNM bleeding event rates were 20.7%/year and 25.6%/year with edoxaban and warfarin, respectively (HR [95% CI]: 0.83 [0.654–1.047]). The event rates of composite outcome were 7.26%/year and 6.86%/year, respectively (HR [95% CI]): 1.06 [0.711–1.587]), and of overall net clinical benefit were 12.48%/year and 12.80%/year, respectively (HR [(95% CI]: 0.99 [(0.730; 1.343]). Increasing CHA 2 DS 2 -VASc score was associated with increased rates of all outcomes. CHA 2 DS 2 -VASc score ≥ 5 was a marker for stent thrombosis. Paroxysmal AF was associated with a higher occurrence of MI (4.87% versus 2.01%, p = 0.0024). Conclusion After PCI in AF patients, increasing CHA 2 DS 2 -VASc score was associated with increased bleeding rates and CHA 2 DS 2 -VASc score (≥ 5) predicted the occurrence of stent thrombosis. Paroxysmal AF was associated with MI. These findings may have important clinical implications in AF patients.
