Interventions

Drug : Among patients with acute coronary syndrome (ACS) treated with drug-eluting stent (DES) implantation, the OPACT-P study will compare two groups: one group will receive dual antiplatelet therap
the other group will receive the same initial 1-month DAPT with aspirin 100 mg once daily and ticagrelor 90 mg twice daily, followed by a switch to aspirin 100 mg once daily and clopidogrel 75 mg once
