      ], dual antiplatelet therapy (DAPT) consisting of aspirin and an oral P2Y12 inhibitor has represented the standard of care for acute coronary syndrome (ACS) or PCI patients due to the greater ischemic protection compared with aspirin alone. Current guidelines recommend 6 or 12 months as default DAPT durations in patients with CCS or ACS undergoing PCI, respectively [
