초록

Despite the use of conventional dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI), the risk of adverse events remains high among patients with increased thrombotic risk. Until recently, the optimal antiplatelet strategy to balance the ischaemic and bleeding risks in patients who are undergoing complex high-risk PCI has been unclear. The TAILored Versus COnventional AntithRombotic StratEgy IntenDed for Complex HIgh-Risk PCI (TAILORED-CHIP) trial is an investigator-initiated, multicentre, prospective randomised trial to evaluate the efficacy and safety of a time-dependent tailored antiplatelet therapy with an early (<6 months post-PCI) escalation (low-dose ticagrelor at 60 mg twice daily plus aspirin) and a late (>6 months post-PCI) de-escalation (clopidogrel monotherapy) in patients undergoing complex high-risk PCI as compared with standard DAPT (clopidogrel plus aspirin for 12 months). Eligible patients had to have at least one high-risk anatomical or procedural feature or clinical characteristic associated with an increased risk of ischaemic or thrombotic events. The primary endpoint was the net clinical outcome, a composite of death from any cause, myocardial infarction, stroke, stent thrombosis, urgent revascularisation, or clinically relevant bleeding (Bleeding Academic Research Consortium type 2, 3, or 5) at 12 months after randomisation. (ClinicalTrials.gov: NCT03465644).
