    Complex percutaneous coronary intervention (PCI) is increasingly performed but carries a higher risk of ischemic events, including stent thrombosis (ST).

  • 2

    Dual antiplatelet therapy (DAPT) is essential after PCI to mitigate thrombotic risks, with extended DAPT often used in complex PCI patients to prevent ST.

  • 3

    Current guidelines suggest varying DAPT durations based on hemorrhagic and ischemic risks, complicating treatment decisions for complex PCI patients.

  • 4

    This meta-analysis aims to evaluate the impact of DAPT duration on ischemic events in patients undergoing complex PCI, addressing a significant knowledge gap.

  • 5

    The study will assess primary outcomes like stent thrombosis and secondary outcomes including myocardial infarction and major bleeding in complex PCI patients.
