Blinding And Interventions
multivessel coronary-artery disease
For the PCI group, angiographic and physiological complete revascularization of target vessels was mandated, and intravascular imaging encouraged. For multivessel coronary-artery disease, all vessels were treated during the index procedure. The placebo group remained sedated, without any further intervention, for at least 15 minutes after randomization.There was no transfer of information regarding the study group assignment to blinded recovery staff. All subsequent medical caregivers were blinded to treatment allocation. The operator and research staff present during the randomization procedure had no further patient contact. Each patient and the recovery team underwent a test of blinding prior to discharge. Patients were discharged with standardized discharge documentation and dual antiplatelet medication on the day of randomization unless otherwise clinically indicated. Details of the blinding framework
