Eligible patients will be randomized in a 1:1 ratio to either an experimental strategy consisting of intravascular ultrasound-guided implantation of a polymer-free drug-coated stent followed by one month of DAPT and subsequent single antiplatelet therapy, or a control strategy consisting of angiography-guided implantation of contemporary drug-eluting stents followed by standard 12-month DAPT.The primary hypothesis is that the experimental strategy will reduce the incidence of net adverse clinical events, defined as a composite of ischemic and bleeding outcomes, compared with conventional PCI and prolonged DAPT. Participants will be followed for 12 months after the index procedure.', 'detailedDescription': 'This study is a prospective, multicenter, randomized controlled trial designed to evaluate an optimized revascularization and antiplatelet therapy strategy in patients with acute coronary syndrome (ACS) who present with both moderate-to-high ischemic risk and high bleeding risk.Eligible patients aged 18 years or older who meet Academic Research Consortium-High Bleeding Risk criteria and have an OPT-CAD score of 90 or higher will be randomized in a 1:1 ratio to an experimental group or a control group. Patients in the experimental group will undergo intravascular ultrasound-guided PCI with implantation of a polymer-free drug-coated coronary stent, followed by one month of dual antiplatelet therapy consisting of aspirin and a P2Y12 inhibitor, and subsequent single antiplatelet therapy. Patients in the control group will undergo angiography-guided PCI with implantation of contemporary drug-eluting stents and receive standard dual antiplatelet therapy for 12 months.Clinical follow-up will be conducted at discharge and at 30 days, 6 months, and 12 months after the index procedure. Clinical data collected during follow-up will include ischemic events, bleeding events, antiplatelet therapy use, and adverse events.The primary endpoint is the incidence of net adverse clinical events at 12 months, defined as a composite of ischemic and bleeding outcomes, including cardiac death, myocardial infarction, ischemic stroke, definite stent thrombosis, clinically driven target vessel revascularization, or bleeding events classified according to the Bleeding Academic Research Consortium criteria. Secondary endpoints include clinically relevant bleeding and ischemic outcomes.Study data will be collected using a centralized electronic data capture system with predefined data validation rules and audit trails. Data quality will be ensured through investigator training, standardized operating procedures, automated range and consistency checks, and regular site monitoring with source data verification against source documents. A predefined data dictionary will describe all registry variables, including definitions, coding information, and clinically relevant ranges where applicable. Missing data will be addressed according to a prespecified statistical analysis plan.The planned sample size is 468 participants, providing adequate statistical power to detect differences in the primary endpoint using an intention-to-treat analytical approach.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False,
