While prolonged DAPT confers thrombotic risk reduction, it invariably increases bleeding complications, which are themselves associated with adverse prognostic implications. This dilemma has prompted the exploration of de-escalation strategies—gradual tapering of antiplatelet intensity or duration—as a means of optimising patient outcomes. Currently, the concept of DAPT de-escalation refers to the strategy of discontinuing aspirin after a short period of dual antiplatelet therapy after PCI, leaving patients on monotherapy with a potent P2Y12 inhibitor—typically ticagrelor, as supported by available evidence. The rationale behind this approach is to maximise ischaemic protection during the initial months after PCI, when the thrombotic risk is highest, while simultaneously mitigating the bleeding risk, which remains relatively constant and is directly associated with DAPT duration.
