Discontinuation of antiplatelet agent group
In this group, antiplatelet monotherapy will be discontinued at the time of randomization. Randomization will be performed at 1 year from the index procedure using DCB angioplasty, standard duration of DAPT (1-3 months), and maintenance of antiplatelet monotherapy at least 1 year from the index procedure in patients with HBR and chronic coronary syndrome. In patients who are still under DAPT at 1 year from index DCB angioplasty, all antiplatelet agents will be discontinued after randomization.
