연구 개요

Comparison of the incidence of major cardiovascular events between the combination of percutaneous intervention and optimal drug therapy and the optimal drug therapy alone in patients with chronic coronary syndrome. * Main RCT (Randomized Clinical Trial): Patients with chronic coronary syndrome enrolled in the study will be randomized in a 1:1 ratio to either 1) PCI(Percutaneous Coronary Intervention) plus optimal medical therapy or 2) optimal medical therapy alone, with clinical outcomes assessed during follow-up. (2,301 participants) * Nested RCT: An embedded randomized supplementary study was conducted on a subset (220 participants) of the total subjects. In patients who have decided to use beta-blockers for the control of angina, additional 1:1 randomization evaluates the efficacy of carvedilol sustained-release (SR) and immediate-release (IR) formulations. Both formulations are targeted for use up to the maximal tolerated dose, taking into account patient symptoms.
