  • Pooled analysis of 3 prospective studies (XIENCE Short DAPT Program)
  • international
  • sex-subgroup analysis
  • propensity score stratification

Authors' conclusion

Among patients at HBR undergoing PCI with everolimus-eluting stents, 1- and 3-month DAPT was associated with similar risk for ischemic events irrespective of sex. In both women and men, 1-month DAPT resulted in less clinically relevant bleeding, although the bleeding risk difference was not significant after propensity score stratification.
