Five hundred fifty‐eight patients presenting with stable angina pectoris and 3‐vessel disease were assigned to and compared among tertiles according to RE and clinical outcomes. The primary end point was the major adverse cardiovascular event (MACE), a composite of cardiac death, nonfatal myocardial infarction (MI), and any repeat revascularization.</p> </sec> <sec id="clc22309-sec-0004" sec-type="section"> <title>Results</title> <p id="clc22309-para-0003">The median follow‐up period was 56.9 months (interquartile range, 52.1–63.6). The incidence of MACE increased significantly as RE increased (13.3%, 31.4%, and 44.1%, log‐rank <italic>P</italic> < 0.001). The same tendency was observed in occurrences of target‐vessel failure (TVF) (a composite of cardiac death, MI, or target‐vessel revascularization) (8.8%, 20.3%, and 28.4%, log‐rank <italic>P</italic> < 0.001), repeat revascularization (11.8%, 26.2%, and 35.6%, log‐rank <italic>P</italic> < 0.001), and MI (1.1%, 2.9%, and 12.6%, log‐rank <italic>P</italic> < 0.001).
