What the trial is, and whether it could suit you

Coronary angiography-guided percutaneous coronary intervention (PCI) remains the standard treatment strategy for patients with coronary artery disease; however, suboptimal post-PCI physiological outcomes remain common and are associated with adverse cardiovascular prognosis. Quantitative Flow Ratio (QFR)-based virtual stenting technology enables simulation of post-intervention coronary physiology before PCI and may facilitate individualized optimization of stent implantation strategies. This multicenter, prospective, randomized controlled trial aims to evaluate whether preprocedural physiological optimization of PCI using coronary imaging-physiology fusion-based virtual stenting technology improves clinical outcomes compared with conventional angiography-guided PCI. Eligible patients undergoing PCI for coronary artery disease will be randomized in a 1:1 ratio to either virtual stenting-

📋 Eligibility rules (as published)
Inclusion Criteria: * Age ≥18 years. * Diagnosis of coronary artery disease requiring percutaneous coronary intervention (PCI) according to current clinical practice. * Presence of at least one target coronary lesion considered suitable for PCI and evaluable by angiography-derived Quantitative Flow Ratio (QFR). * Ability to undergo coronary angiography and PCI. Provision of written informed consent before study participation. Exclusion Criteria: * Contraindications to PCI or inability to undergo coronary intervention. Severe renal dysfunction or other conditions making angiographic procedures unsuitable. * High bleeding risk judged by investigators. * Inability to complete follow-up or comply with study procedures. * Life expectancy less than 1 year due to non-cardiovascular comorbidities. * Participation in another interventional clinical trial that may interfere with study outcomes. * Coronary anatomy unsuitable for QFR-based virtual stenting analysis. * Any condition judged by investigators to make study participation inappropriate.
