CABG indicates coronary artery bypass surgery; HR, hazard ratio; MACCE, major adverse cardiac and cerebrovascular events – composite of death, stroke, myocardial infarction, and repeat revascularization; MACCE‐1, composite of death, stroke, and myocardial infarction; and PCI, percutaneous coronary intervention.
