Patient inclusion flowchart. From an initial cohort of 25,000 patients who underwent coronary revascularization at Asan Medical Center between January 2003 and December 2018, patients undergoing CABG were excluded, and only those with intervention before December 31, 2014 were included to ensure complete 5-year follow-up, resulting in 10,353 patients in the final analysis.
