Antiplatelet therapy after coronary artery bypass surgery: five year follow-up of randomised DACAB trial
Authors' conclusion
Treatment with ticagrelor dual antiplatelet therapy for one year after surgery reduced the risk of major adverse cardiovascular events at five years after coronary artery bypass grafting compared with aspirin monotherapy or ticagrelor monotherapy.
